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.

Claims

1. A heat-radiating structure for quickly and effectively lowering high temperature of a CPU in a computer, comprising a radiating seat, at least one thermal pipe, a radiating member, and a cooling fan, said radiating seat including a central portion and cooling fins arranged at two sides of said central portion, channels and grooves being provided at two lateral ends and upper and lower ends, respectively, of said central portion to receive fastening means therein for fixedly connecting said radiating seat to a radiating block, said central portion being formed with at least one through hole for said at least one thermal pipe to extend one end thereinto, another end of said at least one thermal pipe being extended into and tightly connected to said radiating member, and said radiating member being provided at four corners with threaded holes, so that screws can be threaded through said threaded hole to firmly connect said cooling fan to said radiating member to provide enhanced cooling effect.

2. A heat-radiating structure for CPU as claimed in claim 1, wherein said at least one thermal pipe extended one end into said radiating seat is stamped to be closely fitted in said through hole of said central portion of said radiating seat.

3. A heat-radiating structure for CPU as claimed in claim 1, wherein said threaded holes are provided at said four corners on both side surfaces of said radiating member.

4. A heat-radiating structure for CPU as claimed in claim 1, wherein said radiating member with said cooling fan screwed thereto is adapted to be mounted in a computer housing near ventilation openings provided on the housing, so that heat produced by the CPU as well as other computer components can be radiated by said radiating member and sent out by said cooling fan at the same time to quickly and effectively cool the CPU.
