Publication number: 20070133173Abstract: A compact spray cooling module is presented, which comprises: a storage tank, a spray chamber, a nebulizer, and a media of liquid transportation ability. The storage tank is used for storing a cooling liquid, and the spray chamber is connected to a heat source. Moreover, there is a nebulizer lay on the spray chamber, whereas the nebulizer is comprised of a piezoelectric plate and a micro-nozzle plate. The micro-nozzle plate has a large number of micro-nozzle disposed on it. Furthermore, the media located between the storage tank and the spray chamber has the capability of transporting the cooling liquid from storage tank to spray chamber by capillary attraction for the purpose of nebulizing the cooling liquid. Taking advantage of the latent heat from liquid phase change, the nebulized cooling liquid sprayed to the bottom of the spraying chamber can dissipate the heat generated from the heat source rapidly.Type: ApplicationFiled: March 30, 2006Publication date: June 14, 2007Inventors: Chih-Min Hsiung, Chin-Horng Wang, Szu-Wei Tang, Chiung-I Lee
