Specification of Cold Forged Heat Sink

Description

Cold forged heat sinks are ideal for casting complex shapes with excellent thermal conductivity. The cold forging process can achieve almost perfect straightness, with more heat sinks per square millimeter. The shape of cold forging pin fin heat sink includes plate-fin heat sink, round pin heat sink and oval fin heat sink. The manufacture of forged heat sinks is very suitable for the use of copper, because copper heat sinks can be formed without high temperature and can cause minimal damage. The manufacture of cold forged heat sinks can usually include secondary machining operations, such as holes, chamfering, and steps to reduce unnecessary waste.

Heat sink manufacturers have widely used cold forging technology in the production of light source heat sinks and LED heat sinks. Winshare is one of the few companies that used cold forging to produce heat sinks in the early days. We have accumulated rich experience in cold forging technology. In addition to producing heat sinks for typical light sources, Winshare has also gained experience in manufacturing high-power cold forged heat sinks. We have solved problems such as the low thermal conductivity of die-cast microchannels and the higher cost of processing microchannels. We have applied cold forging heat sinks to cooling solutions, including high-voltage inverters, wind power converters and motor controllers.

1.About the cold forging heat sink

A Forged heatsink is manufactured using a modification of this process called cold forging. Cold forging uses high pressure and low temperature to ensure that no air bubbles, or other impurities are trapped in the material. This improves the thermal properties of the heatsink, and increases the density of the material.

Cold forging uses high pressure and low temperature to ensure that no air bubbles, or other impurities are trapped in the material. This improves the thermal properties of the heatsink, and increases the density of the material. Radian Thermal Products utilizes special open die tooling and intense pressure to produces high precision heatsinks with high aspect ratios. A Forged heatsink is typically manufactured one part at a time, and can be can be made from AL 6063 or C1100. Aspect ratio up to 35:1 are feasible, and no draft angles required on fins. Fins can be round, elliptical, straight or any combination on the same part.

The cold forging process is to forge the product at room temperature. The product has high shape and dimensional accuracy, good internal density, high strength of the workpiece, smooth surface, few processing procedures, and is convenient for mass production.
Cold forged heat sinks are widely used for heat dissipation of LED lamps. The shapes of cold forged heat sink include plate pin fin heat sinks, round pin heatsinks and oval fin heat sinks. Using cold forging heatsink will reduce the overall weight and volume of LED lamps to achieve The purpose of reducing the overall cost is to make the product more competitive!

2.The advantage of cold forging heat sink

The cold forged heat sink is widely used in the heat dissipation of LED lamps and has the following advantages:
(1) The price of cold forging die is not high, which can effectively control the cost;
(2) High production capacity, suitable for mass production;
(3) The mold production cycle is relatively short, usually 10 to 15 days;
(4) One-time molding, the heat dissipation performance of cold forging heatsink is consistent with the heat dissipation performance of the material, and the post-processing procedures are few and simple.
(5)The major advantages of cold forging are close dimensional tolerances, good surface finish quality, and the use of lower cost materials to obtain the required strength by work hardening without requiring heat treatment.

Note

Cold forged heat sink
An added benefit of this process is that a forged heatsink of the same design can be manufactured with different heights using only one set of forging die. When working with high aspect ratio, or dense fins a forged heatsink has no thermal interface between the fins/pins, and the base which will provide better performance compared with stamped-fin or bonded-fin heat sinks. Heat distribution can be further improved in aluminum heatsinks by embedding a copper inserts into the base during the forging. As this process is fairly expensive, for small volumes it may be worth exploring extrusion with a cross cut to produce square pins. For larger volumes die cast is a good alternative.
Fodor has gained experiences in the manufacturing techniques for high power cold forged heat sink. We have resolved the problems such as the low thermal conductivity of die-casting micro-channels and higher costs for machining micro-channels. We have already applied cold forging heatsink to cooling solutions including high-voltage inverters, wind power converters, and electric motor controllers.
