SINGLE ACTUATOR-OPERATED COOLING JET APPARATUS

摘要

Provided is a cooling spray device using a piezoelectric element, comprising an air spray body having a space part formed by coupling, to be airtight, upper and lower layer surfaces formed of resin and/or metal material and provided with a disc-type piezoelectric plate having the piezoelectric property to cross the space part, thereby dividing the space part into first and second chambers, wherein, at least one air pathway for connecting the space part to the outside so as to make air flow into or out from the space part is formed at one side of the air spray body, an air separation film formed by protruding towards the air pathway so as to separate air to be sucked in from air to be discharged is formed at one side of the piezoelectric plate.

1. A cooling jet apparatus using a piezoelectric element,
wherein the cooling jet apparatus comprises an air jet device 4 defining a space via sealing coupling of upper and lower walls 6 and 8 formed using a resin material and/or a metal material, a disk type piezoelectric plate 10a being installed across the space to divide the space into first and second chambers 14 and 16, wherein at least one air passage 12 is formed in one side of the air jet device 4 so as to communicate the space with an outside for introduction or discharge of air into or from the space, wherein an air division film 28 is formed at one side of the piezoelectric plate 10a so as to protrude from the air passage 12, and serves to separate air to be suctioned from air to be discharged, and wherein suction and discharge of air occur simultaneously as the first and second chambers 14 and 16 alternately expand and contract by bending displacement of the piezoelectric plate 10a, whereby a heat generating element is cooled via continuous jetting of the air by the air jet device 4.
