To provide a cooling structure of an electrical component capable of preventing dropping of dew condensation water to the electrical component.SOLUTION: A cooling structure of an electrical component includes a flow path partition plate 17 forming a flow path 16 of heat exchange medium A above an electrical component 11 housed in an enclosure 10, and separating the top face 10a of the enclosure 10 and the electrical component 11. One end of the electrical side flow path 16b on the underside of the flow path partition plate 17, of the flow path 16, is closed and the other end of the electrical side flow path 16b is opened, the heat exchange medium A circulating the flow path 16 flows from one of the outer wall side flow path 16a on the upper side of the flow path partition plate 17 or the electrical side flow path 16b, of the flow path 16, to the other, around the edge of the flow path partition plate 17, i.e., the other end of the electrical side flow path 16b. The flow path partition plate 17 is tilted so as to form a downward pitch from the other end toward the one end of the electrical side flow path 16b.SELECTED DRAWING: Figure 1
【課題】電装品への結露水の滴下を防止し得る電装品の冷却構造を提供する。【解決手段】筐体10内に収容した電装品11の上方に熱交換媒体Aの流路16を形成すると共に、筐体10の上面10aと電装品11との間を上下に隔てる流路仕切板17を備える。流路16のうち、流路仕切板17の下側にあたる電装側流路16bの一端を閉塞すると共に、該電装側流路16bの他端を開放し、流路16を流通する熱交換媒体Aは、流路16のうち流路仕切板17の上側にあたる外壁側流路16a又は電装側流路16bの一方から、電装側流路16bの他端にあたる流路仕切板17の縁を回り込んで外壁側流路16a又は電装側流路16bの他方へ流れ込むよう構成する。流路仕切板17は、電装側流路16bの他端側から一端側に向かって下り勾配をなすよう傾斜配置する。【選択図】図1
