Abstract

A heat dissipation system includes a housing, a circulator and a cooler. The housing has at least one surface made of heat-conductive metal to contact with a heat source. The housing includes a recess with a passage formed on the bottom to contain cooling liquid and an inlet and an outlet connected to the recess. Two pipes are provided to connected between the inlet and the outlet and the cooler, respectively. The circulator is installed in the recess to circulate the flowing of the cooling liquid. As such, heat generated from the heat source is directly conducted to the housing and takes away by the cooling liquid circulated by the circulator to the cooler.

Claims (14)

1. A heat dissipation system for conducting and dissipating heat generated by a heat source, comprising:

a housing with at least one surface made of heat-conductive metal contacted with the heat source, including a recess with a passage formed on the bottom to contain cooling liquid and an inlet and an outlet connected to the recess; and

a circulator installed in the recess to circulate the flowing of the cooling liquid;

a lid covered on the top of the housing and a sealing ring disposed between the lid and the sealing ring to fit the circulator inside the housing;

a cooler having a main body formed by a plurality stacked fins, an inlet tube and an outlet tube, two pipes respectively connected between the inlet and the outlet tube, and the outlet and the inlet tube so that under operation of the circulator, warmer cooling liquid in the housing flowing into the inlet tube through the outlet is cooled down via heat exchange of the fins to provide cooler cooling liquid flowing out from the outlet tube to the housing through the inlet.

2. The system as claimed in claim 1 , wherein the housing has a bottom surface contacted with the heat source.

3. The system as claimed in claim 1 , wherein the surface is made of copper or aluminum.

4. The system as claimed in claim 1 , wherein the passage includes a plurality of apertures.

5. The system as claimed in claim 1 , wherein the passage includes a plurality of protruded columns.

6. The system as claimed in claim 1 , wherein the passage includes a plurality of vortex slots.

7. The system as claimed in claim 1 , wherein the circulator includes a rotator component, a retainer component and a stator component.

8. The system as claimed in claim 7 , wherein the rotator component includes a magnetic pole and an impeller, and the stator component includes a circuit board, a coil and a core.

9. The system as claimed in claim 8 , wherein the impeller is located right above the passage.

10. The system as claimed in claim 1 , further comprising a fan mounted to the main body at the side of the stacked fins.
