Abstract

A porous microchannel structure adopts a first casing and a second casing to form a water block. Water inlet and outlet pipes are extended from both ends of the first casing respectively. The second casing has a porous microchannel structure made by sintering a heat conducting powder and formed on an internal side of the second casing. The second casing has a contact surface on its external side for absorbing and conducting a heat source to the porous microchannel structure, such that a coolant can flow from the water inlet pipe into the water block. The porous microchannel structure produces turbulent flows to the coolant, so as to extend the staying time of the coolant in the water block, and allow the coolant to fully exchange heat with the porous microchannel structure and flow out from the water outlet pipe.

Claims

1. A method of manufacturing a water block, comprising the steps of:

preparing a first casing and a second casing;

pressing and shaping a powder;

putting a tooling at a predetermined position of a second casing;

putting the powder in the tooling;

sintering the powder into a porous microchannel structure; and

coupling the first casing and the second casing to form a water block body.

2. The method of claim 1, further comprising a step of adding a binder on the powder.

3. The method of claim 2, wherein the binder is one selected from stearic acid and wax.

4. The method of claim 1, wherein a shaping machine is used for pressing and shaping the powder.

5. The method of claim 1, wherein the powder is pressed and shaped in a shape selected from the collection of a circular shape, a square shape, and an irregular shape.

6. The method of claim 1, wherein the powder is pressed and shaped in a particle in a shape selected from the collection of a circular shape, a square shape, and an irregular shape.

7. The method of claim 1, wherein the first casing and the second casing are coupled by soldering, riveting, or binding.
