Patent ID: 7269971

Claim:
An electrohydrodynamic (EHD) evaporator device, comprising: an evaporator being a case having a plurality of openings thereon and a metal tube therein being filled with a working fluid; an insulation seat disposed at a refrigerant inlet/outlet or a refrigerant transition so as to avoid electric arc caused by a high voltage when an insufficient insulation is existed between electrodes from occurring; an insulated support member used to fix an electrode and isolate the electrode and metal tube; a voltage applicable insulator comprising a voltage applicable insulator and inputtable by a high voltage; and one or more electrodes disposed in the working fluid and capable of generating an electric field, wherein the working fluid is filled in the metal tube of the evaporator and the electrode is disposed in the working fluid and fixed with the insulated support member and connected to the insulation seat of the voltage applicable insulator at one end, the voltage applicable insulator being installed at an opening of the evaporator case so as to be connected to a high voltage power supplying device.
