The utility model relates to a pressing plate, a heater and an on-board air conditioner, belonging to the technical field of heaters. The pressing plate comprises a plate body and a pressing foot. The plate body is provided with an installation hole, the pressing foot is made of elastic material and is an arc structure, and the pressing foot is arranged on the plate body. The heater comprises a heating core body, an IGBT and the above-mentioned pressing plate, which can be detachably connected to the heating core body, and the pressing foot of the pressing plate holds the IGBT, and the IGBT is fixed to the heating core body under the pressing foot. Vehicle mounted air conditioning includes the above heater. The pressing plate can effectively improve the installation stability of IGBT by pressing and fixing IGBT with elastic pressing feet, and eliminate the adverse effects of processing errors of pressing plate, IGBT and core body on the installation and fixing of IGBT. This heater can effectively prevent IGBT from loosening and ensure its structural stability. The on-board air conditioner can effectively ensure the stable operation of the heater, thereby ensuring its normal work.

压板、加热器及车载空调
本技术涉及加热器
,具体而言,涉及一种压板、加热器及车载空调。
技术介绍
现有的车载空调中的加热器大多是通过PTC(PositiveTemperatureCoefficient,陶瓷片加热器)在高电压下(也有低电压的)发生热量,热量传递给车载系统冷却液,冷却液通过传统空调箱的加热器,以便空调吹风将冷却液热量带出来,使乘员仓加热。但是,对于纯电动汽车供热系统,由于缺少了发动机冷却水作为供热热源,电动汽车使用电能作为能源,因此电动汽车的供热方式有主要有:第一种电加热供热(风),即在HVAC(HeatingVentilationandAirConditioning,空气调节系统)风道中布置PTC加热器,该方案应用较为广泛,其特点为加热迅速,效率高,但这种方案导热高压电进入乘员仓内,且风热PTC在工作时,因周围都是塑料件因此出风常带有异味,导致客户抱怨;第二种为电加热供热(水),即在原有的空调系统基础上,在加热系统中增加高压水加热器,该方案安全可靠,效率高,出风无异味。水加热器中有IGBT(InsulatedGateBipolarTransi ...
