Abstract

A micro pump device with liquid tank comprises a liquid tank being made of transparent material; and a micro pump having an inlet positioned in center of the liquid tank and the micro pump locating the side of said liquid tank. And, the liquid tank further includes a first inlet, a second inlet and a vent hole. The pump device provides a cooling system for micro electric device and a liquid tank could provide a closed tank of cooling system.

Claims

1. A micro pump device with a liquid tank for cooling heat generating electrical circuit components comprising:

a liquid tank being made of transparent material;

a supporting structure being located about the horizontal center of the liquid tank; and

a micro pump having an inlet supported by the supporting structure and positioned in the center of said liquid tank,

where in said liquid tank further includes a first inlet, a second inlet and a vent hole for venting gas.

2. The micro pump device claimed in claim 1, wherein the supporting structure comprises a wall.
