PROBLEM TO BE SOLVED: To provide a heat radiating structure which is hard to allow an electric part to be broken or burned out even if a foreign material enters a flow path of air for cooling the electric part.SOLUTION: A heat radiating structure 500 comprises: a first substrate 510; a second substrate 560 laminated so as to be opposed to the first substrate 510; an insulative covering sheet 520 covering the first substrate 510; an insulative lid provided between the covering sheet 520 and the second substrate 560 so that a ventilation passage S1 which allows air to circulate is formed on the covering sheet 520; conductive members 550A-550C extending between the first substrate 510 and the second substrate 560; and an insulative cylindrical part 540 surrounding the conductive members 550A-550C in the ventilation passage S1. The lid has an upper wall 535 covering a lower face of the second substrate 560. In the lid, an opening 533 for flowing air into the ventilation passage S1, and an opening 534 for flowing out air form the ventilation passage S1 to the outside are formed.SELECTED DRAWING: Figure 5
【課題】電気部品を冷却する空気の流路に異物が混入しても内部の電気部品の破損や焼損が生じにくい放熱構造を提供する。【解決手段】放熱構造500は、第1の基板510と、第1の基板510に対向するように積層される第2の基板560と、第1の基板510を覆う絶縁性の被覆シート520と、被覆シート520上に空気が流通可能な通気流路S1を形成するように被覆シート520と第2の基板560との間に設けられる絶縁性の蓋体と、第1の基板510と第2の基板560との間で延びる導電部材550A〜550Cと、通気流路S1内で導電部材550A〜550Cを包囲する絶縁性の筒状部540とを備える。蓋体は第2の基板560の下面を覆う上側壁535を有する。蓋体には、通気流路S1に空気を流入させる開口533と、通気流路S1から空気を外部に流出させる開口534とが形成される。【選択図】図5
