US 2026/0274038 A1 · DEVICE COOLING SYSTEM AND THERMAL MANAGEMENT SYSTEM

Abstract

A device cooling system includes a vehicle-mounted device, a main controller, and a valve set. A liquid inlet pipe and a liquid outlet pipe are disposed on the vehicle-mounted device, the liquid inlet pipe communicates with the valve set, the valve set is connected to an electric drive liquid-cooling loop to form a first path, the valve set is connected to a battery liquid-cooling loop to form a second path, and the valve set is configured to switch a switch status to control to connect the first path or the second path. A temperature and humidity detection apparatus is disposed in the vehicle-mounted device. The main controller is configured to: obtain a dew point temperature based on a temperature and humidity that are detected by the temperature and humidity detection apparatus, and control, based on the dew point temperature, the valve set to switch the switch status.
