Huahai Technology has achieved the application of highly reliable semiconductor coolers in automotive pre-installed markets such as car climate-controlled seats (CCS), vehicle-mounted hot and cold cups, vehicle-mounted refrigerators, head-up displays (HUD), automotive battery thermal management, automotive radars, and temperature control for automotive cockpit chips. As a pioneer in thermoelectric technology, it possesses the qualification system and capabilities to match automobile manufacturers, striving to optimize the performance of in-vehicle components and provide users with a comfortable and intelligent cabin environment.With the development of 5G technology, the future of automobiles will usher in a fully intelligent era. Due to the limited space in automobiles and the reliance on only a 12V cigarette lighter socket as a power source, semiconductor thermoelectric devices, with their small size and low operating power, can be integrated into smart automobiles as intelligent hardware.
