Title: Evaporation cooler
Inventor: SUGITO HAJIME
IPC: H01L23/427
Filed: 2002-02-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide an evaporation cooler which realizes high efficiency of an evaporating part with low cost.  <P>SOLUTION: A first intermediate plate 5C is adjacent to a heat receiving plate 5A and a second intermediate plate 5D is adjacent to the first intermediate plate 5C. The slit width of an opening part (a first opening part 5a) of the first intermediate plate 5C is larger than the slit width of an opening part (a second opening part 5b) of the second intermediate plate 5D. As a result, when the second intermediate plate 5D is superposed on the first intermediate plate 5C, a tunnel structure (L2>L3) is formed wherein the opening dimension L3 (the opening dimension of the second opening part 5b) of a communicating part which communicates the first opening part 5a with the second opening part 5b becomes shorter than the length L2 (the opening dimension of the first opening part 5a) of a tunnel part. As a result, since evaporation heat transfer is promoted by the increase of bubble foaming points at which refrigerant is evaporated and the formation of a thin liquid film, can be even a heating element having a large heat generating density effectively cooled.  <P>COPYRIGHT: (C)2003,JPO
