Heat sinks are usually made of copper or aluminum. Copper is used because it has many desirable properties for thermal efficiency and durable heat exchangers. Copper is an excellent conductor of heat, this means that copper's high thermal conductivity allows heat to pass through it quickly. Copper stack fin heat sink have excellent heat sink characteristics. Copper's thermal conductivity is approximately twice of aluminum. Copper stack fin heat sink have excellent heat transfer and lightweight.

Copper stacked fin heat sinks are formed by pressing single and multiple pieces together with using high pressure. This copper heat sink formed by press-fitting enables a cooling structure with both top and bottom base plates for mounting power devices. When using this technique, no interface material is required for assembly, and it has the advantage of low development costs and a high degree of flexibility in forming heat sinks of different widths and structures, making it highly versatile. This technology has been widely used for the cooling of high-power devices such as power inverters and transformers, generators, etc...

We can design copper heat sink and run simulation based on customer's requirement, to save the development cost and time.
