3 The Aavid Thermalloy Advantage The Extrusion Process Aavid Thermalloy THE WIDEST SELECTION OF EXTRUDED HEAT SINK SHAPES IN THE INDUSTRY Why choose Aavid Thermalloy as your extrusion supplier? Aavid Thermalloy has over 5,000 extrusion dies available for use. Chances are very good that we have a shape that will suit your needs. Our easy to use "Extrusion Search Tool" on our Web Site at, will guide you in choosing from our most popular shapes. At Aavid Thermalloy, we have built a singular source, under one name, for all your thermal management needs. We dedicate our varied resources to provide you with the optimum cooling solution in the fastest possible time. Establishing an alliance with Aavid Thermalloy at the start of your project will bring this full spectrum of capabilities to your design team. We have manufacturing locations throughout Europe, Asia and North America totaling over m 2 of manufacturing space. Using our global footprint, we can deliver product where you need it, anywhere in the world. Every one of our manufacturing facilities has the ability to produce any level of extrusion design, regardless of complexity. THE AAVID THERMALLOY ADVANTAGE Ideally, working with an existing shape (Aavid Thermalloy has over 5,000 dies available.) is the least expensive option. However, if a custom shape is required, an extrusion die must be produced. Prices for a new die range between 800 and 3000 for most dies that fall within a 180 mm circle size. Prices vary for dies greater than a 180 mm circle size based on size and complexity. An aluminum billet (a round log of aluminum heated to about 480 C) is pushed through the "tool stack" to form the net shape. The tool stack normally involves: 1. a feeder plate to form the billet into a rough geometry of the net shape 2. the extrusion die which forms the net shape 3. a backer and/or bolster plate to support the die plate Extrusion is pushed in 6 to 30 m lengths, straightened and stretched. It is then cut to a length to suit the users needs. Aavid Thermalloy normally stocks product in 5 m sections, however custom lengths are widely used. Consideration of the final cut length of the finished product is taken into account when determining stick length to maximize the yield. There is normally an industry standard minimum number of kilograms involved in a typical "push" of extrusion. These minimums will range from about 225 kilograms to 1100 kilograms based on the shape, size and weight of the part. Aavid Thermalloy offers a variety of our most popular shapes (labeled "A" class and "B" class) at significantly smaller order minimums than the industry standard. We can do this because we have multiple users of the same net shapes. In many instances we will have the more popular extrusions in stock and ready for immediate delivery or use in fabricating your end product. We have our on hand inventory as well as the class listed on our web site,, for your convenience in choosing your desired material.

5 How to Use this Catalog Page Locator Number 1 Mechanical drawing illustrating cross section of an extrusion Dimensions are mm Base extrusion model and part number 0SY39 (400739) Extrusion weight kilograms per meter of length Thermal resistance Natural Convection Thermal resistance Forced Convection Wt: Kg/m : 0.83 C/W : 0.34 C/W HOW TO USE THIS CATALOG Perimeter See page 8 for extrusion class definitions S.A.: 921 mm 2 /mm KEY Kg/m = Weight per meter in kilograms ºC/W = Thermal resistance for a black anodized, 150 mm cut length S.A. = Perimeter in mm 2 /mm Thermal Resistance What does it mean? Thermal resistance is a value that defines the relative performance efficiency of a heat sink in terms of a temperature differential with respect to the power dissipated of ºC/W. In other words, the lower the thermal resistance, the better the performance. Since thermal performance is related to the total surface area (especially in natural convection), the lower the thermal resistance, the larger the heat sink. ºC/W What is this term? It is a relative performance measurement used for comparing and sizing extruded heat sinks. It allows a simplified value to make general comparisons between different shapes. Some qualifiers to consider when using this term: It is based on a uniform thermal load on the heat sink base. It assumes that there are some conductive losses in the part. If there are multiple heat sources or fully uniform heat loading, expect improved performance up to 20%. It is based on a 2 m/s air speed. Pleae refer to the air speed correction graphic on page 13. It is based on a 75ºC temp. sink-to-ambient differential. Please refer to the temperature correction graphic on page 13. It is based on a 150 mm cut length. Please refer to the length correction graphic on page 13 for other lengths. It is based on a black anodized finish. This is preferred for natural convection heat sinks. Expect a double digit percentage increase in thermal resistance if a plain finish is used. It is based on the heat sink oriented in the optimal position. In natural convection, performance is very dependent on the ease of air movement through the heat sink. Positioning the heat sink in other orientations can DOUBLE the thermal resistance.

10 Extrusion Class Definitions EXTRUSION CLASS DEFINITIONS General Information: Extrusions are available in standard bar lengths which are normally 5 m long sections, but length may vary for some shapes. Extrusions are unfinished and may be ordered with a black anodize or chromate finish when purchased cut to size. Part Class (Popularity Code) Based on current popularity, the part class gives an indication of how likely a part is to be in stock. Please visit for stock and classification details. Class A Popular extrusion used by multiple customers. Safety stock is set up on Aavid Thermalloy's system to try and keep some inventory on hand at all times (unless depleted by sudden demand). Re-order points are set up so that we normally have a flow of material within short lead times. Class B Moderately popular extrusion used by multiple customers. Strong likelihood of some material being available from stock or on backorder. When inventory is depleted we will re-order upon demand with minimal lead times and NO set up charges. Class C Low demand / low usage extrusion with few / one customer demand. About a 35% chance of material in stock at time of order. If material is not in stock at time of order, a set up charge will apply. Normal minimum run is generally 500 kg for less than 180 mm circle size, 1,000 kg for greater than 180 mm circle size.

12 Extrusion Design Suggestions Extrusion Design Suggestions There are a number of design suggestions in the section below. Incorporating some/many of these design suggestions into your final product should allow you to come up with a more cost effective design. DESIGN SUGGESTIONS 60 Incorporate a "screw boss" into the design to save the cost of drilling a hole. You can use a thread-forming / self-tapping screw during assembly. Recommended opening of 60 degrees for ease of extrudability. Add an "ID" mark such as a small depression or ridge to a non-exposed surface/area of the extrusion design. This could serve as a guide to where holes should go, allow people to tell one side from another during machining or assembly or to differentiate material between two or more suppliers of the same shape. Incorporate bolt head channels for bolt heads or nuts to facilitate assembly. Other criteria for the design and selection of a heat sink should include: Base plate thickness Ease of manufacturing Fin height, spacing, thickness Dove-tails, interlocking or snap-fit joints can be designed to mate pieces together. Try designing a 2-piece extrusion as it may reduce the cost of secondary fabrication or it may be less costly to manufacture in terms of material and/or tooling costs. Orientation of fins Type of material Weight To save machining time, incorporate PC board slots or serrated extruded slots for threaded hardware into the extrusion design. Aavid Thermalloy Max Clip Semi-conductor power device Uniform Non-Uniform When locating a thru or tapped hole in the extrusion, make an effort to allow clearance on the other side or design such that the hole does not break through. If a thru or tapped holes falls into a fin or other feature on the opposite side, it makes it difficult to hold the integrity of the thread, the location of the hole and it also makes it difficult to remove burrs caused by the machining. Extruded rails for mounting clips saves assembly costs. When designing fins or other related features, attempt to keep the features as uniform in thickness as possible to allow for the extrusion to fill properly. Do not design heavy masses adjacent to smaller/narrow features. Adding a taper to a fin (thicker at base, thinner at tip) allows for easier extrudability.

Effects of Anodization on Radiational Heat Transfer Heat sinks cooled by natural convection may benefit from an anodized finish, but the added cost of the finish may not be justified when the part is used in forced convection cooling. Surface emissivity limits the amount of heat transfer due to radiational cooling. With 1.0 being perfect (black body), the emissivity of anodized aluminum is 0.85 and unfinished is Heat transfer due to radiation is proportional to the heat sink surface area exposed to its surroundings and to the temperature rise above ambient (in absolute K) raised to the 4th power (T sink-ambient) 4. In natural convention on small heat sinks with open fins, radiational heat transfer may be as much as 25% of the total. Relatively large extrusions and those used at low temperature rise, as in many high power applications, will only gain up to 10% by the addition of an anodized surface. With forced ventilation (using a fan) convective heat transfer is about 4 times higher than in natural convection. This changes the proportion of heat transfer due to radiation. An anodized finish will only add 4-8% to the overall cooling effect in forced air. This percentage again, depends on fin spacing and heat sink dimensions. The color of the anodized finish makes little impact on emissivity since most radiational heat loss occurs at wave lengths higher than visible light. As a rule of thumb, if anodization is not required for aesthetic or corrosion protection, we recommend it only for small, open finned heat sinks in natural convection.

15 Correction Considerations Temperature, Length and Air Speed 75ºC DELTA T THERMAL RESISTANCE vs (Ts - Ta) DELTA T = (HEAT SINK TEMP. -AMBIENT TEMP.)ºC TEMPERATURE CORRECTION FACTOR Both natural convection and radiation coefficients are related to the sink-to-ambient temperature difference. To evaluate the thermal performance of a heat sink for an application requiring a sink-toambient temperature rise other than 75 ºC, use the correction factor from the thermal resistance vs (Ts - Ta) graph shown. This factor must be used only for thermal resistance in natural convection. CORRECTION CONSIDERATIONS THERMAL RESISTANCE vs LENGTH LENGTH CORRECTION FACTOR EXTRUSION LENGTH mm Because the air heats up while circulating through the extrusion, the convection coefficient is not constant throughout the extrusion length. Therefore, the thermal resistance changes nonlinearly as the length changes. To calculate the correct thermal resistance for extrusion lengths other than the standard 150 mm length, multiply the given thermal resistance data by the appropriate factor taken from the thermal resistance vs length graph shown. The same correction factor must be used for thermal resistance in both natural convection and forced convection THERMAL RESISTANCE vs AIR SPEED AIR SPEED m/s AIR SPEED CORRECTION FACTOR The convection coefficient is also closely related to the air speed through the fins. Since evaluation of air speed through the fins is difficult to evaluate under normal circumstances, we show the thermal resistance of an extrusion in forced convection evaluated using a tunnel the same size as the extrusion. For a tunnel airflow other than 2 m/s, refer to the factor in the thermal resistance vs air speed graph shown. Use this factor to figure thermal resistance in forced convection.
