[0002] The heat dissipation module is a modular component designed for the heat dissipation needs of electronic equipment. It is mainly used to transfer the heat generated inside the device to the external environment to keep the device running within a suitable temperature range. The heat dissipation module usually contains components such as heat sinks, heat pipes, fans, etc., and achieves efficient heat transfer and heat dissipation through reasonable design combinations. The heat dissipation module is mainly composed of a heat dissipation base, heat pipes, heat dissipation fins and fans. The heat dissipation base is close to electronic components, such as the CPU or GPU, and is responsible for receiving the heat generated by the components; the heat pipe conducts the heat from the heat dissipation base to the heat dissipation fins; and the fan helps the heat dissipation fins release heat by forcing air flow to ensure that the device temperature is controlled within a safe range.

When dust removal is required, the operator must remove the entire heat dissipation module from the heat source, then remove the fins from the fan, clean and dust them separately, and then reinstall them on the heat dissipation fan. The operation is cumbersome, and frequent disassembly and assembly can easily cause structural damage to the heat dissipation module. Therefore, the heat dissipation module in the prior art lacks a convenient dust prevention method, which affects the product market reputation and needs to be improved urgently.
