Description

Technical Field

[0001] This utility model relates to the field of ceramic heater technology, and more specifically, to a modular structure integrating an MCH nano-ceramic heater with a compressor. 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] Pure resistance heating (PTC): Although it has a fast response and simple structure, it has low energy efficiency (COP≈1) and high energy consumption when operating at high power, which will lead to a significant reduction in range in electric vehicles. Pure heat pump (compressor): The heating efficiency drops sharply in low-temperature environments (such as below -10℃) (COP drops from 3.0 to below 1.5), and it requires complex defrosting logic, which affects stability; traditional PTC heaters and compressors are arranged independently, with complex piping and large refrigerant charges, resulting in large thermal inertia and response delay. The separate components occupy a lot of space, making it difficult to meet the layout requirements of compact equipment (such as electric vehicles).

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