Miniature pump for liquid cooling system

摘要

A miniature pump in accordance with the present invention comprises a pump casing ( 1 ) and a liquid circulating unit ( 2 ) received in the pump casing. The pump casing defines an enclosed space ( 15 ) for storing liquid therein. A spacing plate ( 12 ) is arranged in the pump casing to divide the enclosed space into a first chamber ( 16 ) and a second chamber. The spacing plate defines a through opening ( 122 ) at a center portion thereof to make the first and second chambers communicate with each other. An inlet ( 104 ) and an outlet ( 110 ) are formed on the pump casing respectively communicating with the first and second chambers. The liquid circulating unit is mounted in the second chamber for circulating the liquid in a liquid cooling system.
