Description

Technical Field

[0001] This utility model relates to the field of ceramic heater technology, and more specifically, to a high-pressure liquid nano-ceramic electric heater for automobiles. Background Technology

[0002] New energy vehicles are the future trend of automotive development. Unlike traditional fuel vehicles, new energy vehicles do not have engines, which makes in-vehicle heating a problem. Ceramic heaters are high-efficiency heaters with uniform heat distribution and are made of metal alloys with excellent thermal conductivity, ensuring uniform surface temperature and eliminating hot and cold spots in the equipment.

[0003] Ceramic heaters are the best choice for hot air in new energy vehicles, especially in the north. In winter, the lack of heating in the car is a torment for the driver and passengers. Simple heaters have low heating efficiency and are not only complex in structure but also expensive.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A waterproof and breathable valve is located on the side of the housing. A temperature sensor is located inside the housing above the heating elements. Cover plates are provided on the top and one side of the housing.

[0008] Preferably, the heating element includes a ceramic tube, the end of which is provided with a flange, the flange is provided with a positioning element, the positioning element is provided with a sealing element for sealing, and the ceramic tube is provided with an electrode connected to the integrated controller.

[0009] Preferably, a temperature-sensitive substrate is fitted onto the outer surface of the ceramic tube, and a heating substrate is fitted onto the outer surface of the temperature-sensitive substrate.

[0010] Preferably, the circular tube is located on a stainless steel circular tube, and its two ends are provided with fixing plates for fixing, the fixing plates having a plum blossom shape structure.

[0011] Preferably, the housing is provided with a water channel to accommodate the heating element, and the top opening of the water channel is provided with a mounting hole that matches the second pressure block. The second pressure block is connected to the water channel by bolts.

[0012] Preferably, the top of the waterway has a blind hole for the temperature sensor to extend into, and the housing has reinforcing ribs.
