Abstract
Description
Technical Field
[0001] This utility model relates to the field of PTC heater technology, and more specifically, to a warm air PTC heater with a vent valve mounting structure. Background Technology
[0002] As new energy vehicles represent a key direction for national industrial development, more and more OEMs and component manufacturers are participating, leading to fierce competition among different brands. With the initial consumer concerns about driving range and battery safety gradually resolved, higher demands are now being placed on other aspects such as comfort. Currently, new energy vehicles do not rely on engine coolant for heat generation like traditional vehicles; instead, air conditioning heating primarily depends on onboard PTC heaters. Taking a controlled air-heating PTC heater as an example, this type of heater is currently the most common in the market. Its working principle involves powering the PTC controller through the vehicle's high-voltage battery. The air-heating heater then controls its power output to regulate its heat generation. Existing air-heating heaters require the addition of a vent valve. Without a vent valve, the PTC controller housing will experience pressure differentials due to thermal expansion and contraction, potentially causing casing deformation or creating a sealed space within the PTC element, thus affecting its lifespan.
[0003] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
[0004] In view of the problems in related technologies, this utility model proposes a breather valve mounting structure for a warm air PTC heater to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] Therefore, the specific technical solution adopted by this utility model is as follows:
[0006] A breather valve mounting structure for a warm air PTC heater includes a PTC body and a controller assembly. The controller assembly is mounted on one side of the PTC body, and a breather valve is mounted on the side of the controller assembly. The breather valve is connected to the controller assembly through a limiting structure.
[0007] Preferably, the limiting structure includes a mounting hole located on the side of the controller assembly, the vent valve is provided with a screw for moving through the mounting hole, and the controller assembly is provided with a nut that is threadedly connected to the screw.
[0008] Preferably, a sealing ring is provided at the mounting hole and fitted onto the screw.
[0009] Preferably, a limiting groove for limiting the sealing ring is provided at the corner of the mounting hole.
[0010] Preferably, a protective cover is provided on one side of the controller assembly and fitted onto the vent valve.
[0011] The beneficial effects of this utility model are as follows: through the setting of the vent valve and the limiting structure, its special vent valve installation structure improves the installation efficiency, stability and consistency of the vent valve, and the addition of the limiting groove to the vent valve structure increases the waterproof stability of the vent valve.
