CPU cooling device

The utility model discloses a CPU cooling device, and relates to the technical field of computers. The CPU cooling device comprises a CPU body, a heat conducting silica gel layer, a base, a first air guide pipe, a second air guide pipe, a cooling shell, a fan, an air outlet fan and cooling fins. The CPU radiating device is reasonable in structural design, novel and unique in model, easy to operate and convenient to use; as the heat conducting silica gel layer is arranged between the base and the CPU body, heat of a CPU can be effectively transmitted to the base, and the cooling effect is improved; the dual-air-guide-pipe design is adopted, so that the heat can be effectively transmitted out; the design of a fan and air outlet fan loop is adopted, so that the cooling effect is further improved.
