MICROPUMP AND SEMICONDUCTOR DEVICE USING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a micropump autonomously operating without supply of electric energy from the outside. <P>SOLUTION: This micropump includes: a high temperature side member located on a heat source side; a low temperature side member located on a heat radiation side; an intermediate layer located between the high temperature side member and the low temperature side member; and a chamber forming a part of a flow passage between the intermediate layer and the low temperature side member. The intermediate layer includes: a diaphragm; and displacement means for displacing the diaphragm by heat absorption from the high temperature side member and heat radiation from the low temperature side member. The diaphragm displaces between a first position before displacement and a second position in contact with the low temperature side member by the displacement to take in fluid into the chamber and discharge fluid from the chamber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
