热介质加热装置及具备该装置的车辆用空调装置
摘要：
本发明的目的在于，提供一种热介质加热装置及具备该装置的车辆用空调装置，其能够尽量减小热介质加热装置的高度方向尺寸而实现小型化，并且提高在控制基板上连接线束类时的操作性。一种热介质加热装置（10），将多个扁平换热管（21）和多组PTC加热器（26）层叠多层而构成的热交换元件（20）紧固固定于具备热介质的出/入口通路（15、16）的壳体（11）内，其中，在壳体（11）的设有热介质出/入口通路（15、16）的一面的相同面侧的外表面设有电源用HV线束及控制用LV线束（44）的连接部（48、49），并且在壳体（11）的设有连接部（48、49）的一面的相同面侧的内部设置有控制向PTC加热器（26）的通电的控制基板（33）。
摘要（英）：

The invention aims to provide a heat medium heating device and a vehicle air conditioner including the same which can reduce the hight size of the heat medium heating device as much as possible to realizing miniaturization, and improve the operability of connecting wire bundles on a control substrate. In a heat medium heating device 10 in which a heat exchange element 20 formed by stacking multiple flat heat exchange tubes 21 and multiple pairs of PTC heaters 26 in multiple layers is fastened and fixed into a casing 11 including heat medium outlet and inlet paths 15 and 16, connection portions 48 and 49 between a power supply HV harness and a control LV harness 44 are provided on an outer surface on one surface side where the heat medium outlet and inlet paths 15 and 16 of the casing 11 are provided, and a control substrate 33 that controls energization to the PTC heaters 26 is disposed on an inside on the same side as a surface on which the connection portions 48 and 49 of the casing 11 is provided.
