To provide a structure capable of efficiently cooling a power transmission apparatus and a power reception apparatus that have coils arranged to be laminated.SOLUTION: A power reception apparatus 30 of a non-contact power feeding system 10 that feeds power in a non-contact manner, comprises: a plurality of power reception coils 36u, 36v and 36w; a cooling part 40 having a cooling surface 41; and a pedestal part 45 provided between the respective power reception coils 36u, 36v and 36w and the cooling surface 41 of the cooling part 40. The plurality of power reception coils 36u, 36v and 36w are laminated on the cooling surface 41 so as to be deviatedly disposed in a direction orthogonal to the lamination direction at a predetermined interval, and thus, each power reception coil 36u, 36v and 36w is provided with an opposed part 36c opposed to the cooling surface 41 of the cooling part 40 without interposing the other power reception coil. The pedestal part 45 has an uneven configuration so as to fill a space between the opposed part 36c of each power reception coil 36u, 36v, 36w and the cooling surface 41 of the cooling part 40.SELECTED DRAWING: Figure 3
【課題】積層配置されたコイルを有する送電機器及び受電機器を効率的に冷却する構造を提供することにある。【解決手段】非接触で給電を行う非接触給電システム10の受電機器30において、複数の受電コイル36u,36v,36wと、冷却面41を有する冷却部40と、各受電コイル36u,36v,36wと冷却部40の冷却面41との間に設けられた台座部45と、を備え、複数の受電コイル36u,36v,36wが、冷却面41上で積層されるとともに、積層方向と直交する直交方向に所定間隔でずらされて配置されることにより、各受電コイル36u,36v,36wには、他の受電コイルを介在させることなく冷却部40の冷却面41に対して対向する対向部36cがそれぞれ設けられており、台座部45は、各受電コイル36u,36v,36wの対向部36cと冷却部40の冷却面41との間を埋めるように、凹凸形状を有する。【選択図】 図3
