<p><P>PROBLEM TO BE SOLVED: To provide a heat absorption structure for an outdoor device capable of efficiently cooling the inside of an outdoor housing by absorbing an incident amount of heat using the phase change of phase change materials. <P>SOLUTION: A device arrangement region 15 where an electronic device 3 is arranged, a passage region 18 positioned along an external plate 13, and a heat absorption region 16 positioned vertically above the device arrangement region 15 and the passage region 18 and having a PCM member 4 in which a phase change material is sealed are disposed. By forming a circulation route through which gas circulates the passage region 18, the heat absorption region 16 and the device arrangement region 15, the gas inside the passage region 18 heated by an incident amount of heat flows into the heat absorption region 16 where the gas is heat absorbed and cooled using the phase change of the phase change material, then the gas thus cooled flows into the device arrangement region 15. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
