PROBLEM TO BE SOLVED: To provide a small pump of a thin type that can be favorably applied to a cooling device for an electronic device such as a notebook personal computer that is becoming thinner and smaller. SOLUTION: This small pump comprises a diaphragm that is reciprocated and vibrated by a piezoelectric element and a case main body. An intake nozzle part and a discharge nozzle part are formed on an outside part of the case main body. The intake nozzle part is communicated with an intake part through an intake passage. The discharge nozzle part is communicated with a discharge part through a discharge passage. The intake nozzle part and the discharge nozzle part are disposed above the diaphragm at least partly. The intake passage and the discharge passage connected to the nozzle part are partly disposed above the diaphragm. COPYRIGHT: (C)2005,JPO&NCIPI |
