With the continuous increase of power of electronic components such as CPU (Central Processing Unit ), GPU (Graphics Processing Unit, graphics processor), PCH (Platform Controller Hub, integrated south bridge), the problem of heat dissipation is more and more emphasized, especially in notebook computers. In order to efficiently carry away the heat generated by the system in a limited space, a heat dissipation module consisting of heat dissipation fins, heat pipes and fans is mainly used for heat dissipation in the industry at present. The heat conduction path of this embodiment is: heat generated by electronic components such as a CPU is conducted to the radiating fins through the heat pipe, and then air flow generated by the fan and the radiating fins are subjected to heat exchange so as to take away the heat transferred to the radiating fins.
