We have become the preferred partner of many global leading companies in the field of high heat flux density cooling, jointly pushing the technological frontier. -
Q What is the working fluid inside the heat pipe? Is it safe?
A The working fluid inside the heat pipe is selected according to the operating temperature range, the most commonly used is water, in addition to methanol, acetone, ammonia, etc. These fluids are sealed inside the heat pipes and do not leak into the outside environment. The working fluid and manufacturing processes we use comply with environmental and safety standards, ensuring that the products are harmless to humans and the environment.

Q What are the significant differences in heat dissipation performance between cold forged heat sinks and extruded heat sinks?
A Cold forged heat sinks are usually better than extruded heat sinks in terms of heat dissipation performance. The main reason is that cold forging can achieve a fin structure with higher density and aspect ratio, greatly increasing the heat dissipation surface area; more importantly, the cold forging process allows the substrate and fins to be formed in one piece, fundamentally eliminating the interface thermal resistance and ensuring efficient and lossless heat transfer. Extruded heat sinks are limited in fin density and aspect ratio, and may have higher interface thermal resistance.
-
Q What is the difference between heat pipes and vapor chambers?
A Heat pipes are linear heat transfer elements primarily used to transfer heat from one point to another. The vapor chamber can be understood as a two-dimensional planarized heat pipe, which can quickly diffuse and homogenize heat across the entire surface, suitable for surface uniformity of high heat flux density chips, and provide stronger local heat dissipation capabilities.
-
Q What materials are mainly used in cold forged heat sinks? What are the advantages of these materials?
A Cold forged heat sinks mainly use high-purity aluminum (such as AL1050, AL1070) and copper. These materials have excellent thermal conductivity. Through the cold forging process, their grain structure is optimized, the thermal conductivity is further improved, and they also have good mechanical strength, which can meet the heat dissipation needs of high-power devices.
