热介质加热装置及使用了该装置的车辆用空调装置
摘要：
一种热介质加热装置（10），具备：与PTC加热器（40）的两面密接且在内部形成有热介质流通路径（33、54）且彼此液密地接合的第一热介质流通箱（A）及第二热介质流通箱（B）；设置于例如第一热介质流通箱（A）且与热介质流通路径（33）相邻的电气部件冷却壁部（26）；及固定于该电气部件冷却壁部（26）的电气部件（23a），在电气部件冷却壁部（26）的热介质流通路径（33）侧的面上形成有位于电气部件（23a）的设置位置的正背面且向热介质流通路径（33）侧延伸的突出部（26a）。该突出部（26a）兼作为将电气部件（23a）紧固于电气部件冷却壁部（26）的紧固构件（25b）的紧固凸起。
摘要（英）：

The disclosed heat-medium heating device is provided with: a first heat-medium circulation box (A) and a second heat-medium circulation box (B) that are in close contact with two sides of a PTC heater (40), respectively, and are joined to each other in a liquid-tight manner; an electrical-component cooling wall section (26); and electrical components (23a) affixed to the electrical-component cooling wall section (26). Heat-medium circulation channels (33 and 54) are formed inside the first and second heat-medium circulation boxes (A and B). The electrical-component cooling wall section (26) is provided for example in the first heat-medium circulation box (A), adjacent to that heat-medium circulation channel (33). On the surface of the electrical-component cooling wall section (26) facing said heat-medium circulation channel (33), protrusions (26a) that extend into said heat-medium circulation channel (33) are formed at positions precisely opposite the positions where the electrical components (23a) are seated. Said protrusions (26a) also serve as fastening bosses for fastening members (25b) that fasten the electrical components (23a) to the electrical-component cooling wall section (26).
