Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to an anti-corrosion heat dissipation sheet. Background Art

[0002] A radiator is a heat dissipation device used to quickly dissipate heat from a heat source. The heat sink is the main heat dissipation component of the radiator. The heat dissipation efficiency can be effectively improved by installing multiple heat sinks in the radiator. Most of the existing heat sinks are made of metal. In some relatively humid working environments, they are more susceptible to moisture corrosion, which greatly reduces the practical life of the radiator. At the same time, it will increase the failure rate of the radiator and cause other electronic components to burn out due to excessive temperatures. Therefore, improvements are needed.
