Abstract

A liquid cooling device includes a casing (10), a liquid inlet port (18) and a liquid outlet port (19) in communication with the casing (10). The casing (10) includes a heat-absorbing base (11). The base (11) includes a porous layer interior of the casing (10).

Claims

1. A liquid cooling device comprising:

a casing comprising a heat-absorbing base, the base comprising a porous layer interior of the casing;

liquid accommodated in the casing;

an actuator,

pipes connecting the casing and the actuator,

a liquid inlet port which renders the liquid to enter the casing; and

a liquid outlet port which allows the liquid to leave the casing when actuated by the actuator.

2. The liquid cooling device of claim 1, wherein the layer is made of sintered metal powder.

3. The liquid cooling device of claim 1, wherein the layer is made of foaming metal.

4. The liquid cooling device of claim 1, further comprising a heat sink connected to the pipes.

5. A liquid cooling device for a heat-generating component, comprising:

a casing disposed next to said component, comprising a heat-absorbing base thermally contacting with said component for heat transmission from said component via said base, and a container used to receive cooling liquid therein;

a cooling liquid circulation system connected to said casing and in communication with said container for said cooling liquid so as to urge said cooling liquid flowing into said container for said heat transmission and out of said container for heat dissipation; and

at least one porous layer formed in said casing next to said base and in communication with said container so that liquid in said container is accessible and containable in said layer for said heat transmission.

6. The liquid cooling device of claim 5, wherein said layer is made of sintered metal powder and formed on a side of said base facing said container.

7. A method for cooling a heat-generating component, comprising the steps of

providing a casing having a cooling-liquid-receivable container and a heat-absorbing base disposed next to said container for thermally contacting with said component;

circulating cooling liquid between said casing and a radiator so that said cooling liquid absorbs heat from said component via said base in said container and dissipates said heat via said radiator, and

sucking said cooling liquid via a porous layer formed in said casing next to said base for enhancing heat absorption of said liquid in said container.

8. The method of claim 7, wherein said layer is made of sintered metal powder and formed on a side of said base facing said container.
