How does a Cold Forged Heat Sink work?
- Heat Absorption: When your device is running at high speeds, it generates a lot of heat.
- GALLOP INNOTEK’s cold-forged heat sink absorbs heat quickly, preventing equipment from shutting down due to high temperatures.
- Heat Dissipation: GALLOP INNOTEK cold-forged heat sinks also efficiently dissipate heat away from the heat-generating element to keep the temperature of your equipment within normal limits.
Advantages of Cold Forged Heat Sink
Superior Thermal Conductivity: GALLOP INNOTEK cold-forged heat sinks are made from aluminum or copper. They are metals with very high thermal conductivity, and the cold forging maintains their excellent thermal conductivity.

Why Cold Forged Heat Sink？
- One-piece moulding: The GALLOP INNOTEK cold forging process can form high-quality one-piece heat sinks through strong stamping. Other processes, such as extrusion, require secondary processing to achieve three-dimensional one-piece moulding.
- No Heat Required: GALLOP INNOTEK cold-forged heat sinks do not require high-temperature heating. It is suitable for temperature-sensitive components. This also reduces energy losses and costs.
- Better quality: The GALLOP INNOTEK cold-forged heat sink provides superior hardness, surface finish, and dimensional accuracy. It also exhibits excellent heat transfer capabilities
- Lightweighting Requirements: GALLOP INNOTEK offers cold-forged heat sinks that minimize the weight of the heat sink while maintaining your heat dissipation needs, allowing you to use them for weight-restricted equipment.
- Tight Space Requirements: GALLOP INNOTEK’s cold-forged heat sink is also capable of creating complex cold-forged heat sinks with high precision, providing effective heat dissipation for small devices. Additionally, it is able to withstand vibration and shock, ensuring long-lasting durability.
Applications of Cold Forged Heat Sink
- Electronic Devices: Electronic devices such as mobile phones, tablets, and computers must be efficiently cooled to maintain proper operation. You can choose GALLOP INNOTEK’s cold forged heat sinks for excellent performance and durability.
- LED Lighting: High-power LED lighting and industrial lighting generate significant heat, which affects their brightness and lifespan. Using the GALLOP INNOTEK cold forged heat sink to solve this problem effectively.
- Automotive: For the automotive industry, GALLOP INNOTEK’s cold-forged heat sinks not only dissipate heat from the battery system and electronic control systems but also reliably cool the car’s lights.
- Telecommunications: GALLOP INNOTEK cold-forged heat sinks are used in telecommunication equipment to meet the stringent thermal requirements and ensure its 24/7 operation.
A cold forged heat sink is a passive radiator that provides efficient heat dissipation without the need for an external power source. It is made of high thermal conductivity materials such as aluminium and copper and relies on natural convection, radiation and conduction to quietly transfer heat away from the equipment and reduce its temperature.
Compared to extruded heat sinks, the one-piece design of cold forging maximises heat transfer efficiency. Die cast radiators can also be moulded in one piece and at a lower cost, making them a cost-effective option, but the mechanical properties of the heat sinks are not as good as those of cold forged. Cold forged heat sinks also offer very strong mechanical properties and a refined design.
