<P>PROBLEM TO BE SOLVED: To sufficiently cool electronic components, regardless of the temperature of outdoor air, and reduce the energy required for cooling the electronic components in a cooling device for cooing electronic components of a power conditioner for a solar energy generation system. <P>SOLUTION: A heat accumulator (30), a heat sink (35), a heat pipe (40) and a heat insulation case (50) are provided at a cooling device (25). The heat accumulator (30) includes a latent heat storage agent (32) and is thermally connected to an electronic component (21) of a power conditioner. The heat sink (35) is disposed above the heat accumulator (30). The heat pipe (40) is thermally connected to the heat accumulator (30) at a lower end and to the heat sink (35) at an upper end. The heat accumulator (30) and the electronic component (21) are covered by a heat insulation case (50). Heat generated by the electronic component (21) at daytime is accumulated in the heat accumulator (30). The heat accumulated in the heat accumulator (30) is transferred to the heat sink (35) by the heat pipe (40) at nighttime to be discharged to the outdoor air. <P>COPYRIGHT: (C)2012,JPO&INPIT |
