Abstract

The invention relates to heat dissipation devices, in particular to a thin sheet type CPU heat dissipation device and a machining method thereof. The thin sheet type CPU heat dissipation device comprises a heat transmission and heat dissipation integrated device, wherein the heat transmission and heat dissipation integrated device is formed by stamping, and network channels are formed inside the heat transmission and heat dissipation integrated device. The network channels are filled with certain amount of heat transmission working media from technological filling ports and are sealed through welding. The heat dissipation device comprises a heat transmission substrate and a heat dissipation part, wherein the heat transmission substrate in contact with a CPU is of a protruding structure, and the portion outside the heat transmission substrate is the heat dissipation part. Mirror surface machining is carried out on the surface, in contact with the CUP, of the heat dissipation substrate. An efficient heat transmission technology is adopted in the thin sheet type CPU heat dissipation device and the manufacturing method thereof, heat generated by the CPU is made to be transmitted to a heat dissipation end fast, and the heat dissipation end carries out heat exchange with ambient air to ensure the normal work of the CPU.
