Abstract: Disclosed is a heat-radiating structure for CPU mainly including a radiating seat, at least one thermal pipe, a radiating member, and a cooling fan. The radiating seat is connected to a radiating block attached to the CPU, so that heat produced by the CPU can be transmitted to the radiating seat via the radiating block. The at least one thermal pipe is connected at one end to the radiating seat and at the other end to the radiating member to enhance heat transmission from the radiating seat to the radiating member. The cooling fan is screwed to one side surface of the radiating member to speed dissipation of heat transmitted to the radiating member.
