High-pressure water heating PTC (Positive Temperature Coefficient) assembly of automobile air conditioner

The utility model is applicable to the technical field of liquid heating PTC (Positive Temperature Coefficient) assemblies, and provides a high-pressure water heating PTC assembly of an automobile air conditioner, the internal space of a water heating chamber is divided into a closed flow channel by a plurality of heating grooves and baffles arranged at the bottom of a heating aluminum seat, and the closed flow channel is used for the flowing of cooling liquid; cooling liquid enters the flow channel through the water inlet and flows according to a cooling liquid path, heat released by the heating unit is absorbed in the flowing process, the cooling liquid flows out of the water outlet, the cooling liquid flows to a battery and a warm air core in a whole vehicle system, and heat energy needed by a whole vehicle is achieved. The performance efficiency of the PTC is effectively improved, the same heat exchange performance is realized by adopting fewer heating units, and the required performance indexes are achie
