The invention belongs to the technical field of electric heaters, and particularly relates to an automobile air conditioner PTC heater which comprises a shell and a plurality of PTC heating core bodies arranged in the shell, the PTC heating core bodies are located on the front side wall of the shell, an air inlet is formed in the rear side wall of the shell, a filter screen is fixedly installed in the air inlet, and the PTC heating core bodies are arranged in the shell. The two ends of the shell are fixedly connected with a tank body and a water storage box respectively, a water pump is fixed in the water storage box, and the output end of the water pump is fixedly connected with a water supply pipe penetrating through the water storage box. When the heater works, water in the water storage box is pumped into the tank body, when the heater is turned off, the water in the tank body flows back into the water storage box downwards, on one hand, heat on the PTC heating core body can be quickly adsorbed and brought out, and the situation that elements are damaged due to heat accumulation in the heater is avoided; on the other hand, after the water in the tank body is discharged, the scraper moves downwards to clean the filter screen, and it is guaranteed that the filter screen can continuously conduct follow-up airflow filtering work.
本发明属于电加热器技术领域,尤其涉及一种汽车空调PTC加热器,包括壳体和设于壳体内的多个PTC发热芯体,所述PTC发热芯体位于壳体的前侧壁,所述壳体的后侧壁开设有进风口,所述进风口内固定安装有滤网,所述壳体的两端分别分别固定连接有罐体和储水盒,所述储水盒内固定有水泵,所述水泵的输出端固定连接有贯穿储水盒的送水管。本发明在加热器工作时将储水盒内的水体泵入至罐体内,在加热器关闭时,罐体内的水体往下流回至储水盒内,一方面能快速将PTC发热芯体上的热量吸附带出,避免加热器内部热量堆积损坏元件,另一方面罐体内水体排出后刮板下移进行滤网的清理,保证了滤网能持续进行后续气流的过滤工作。
