Abstract

The invention provides a system and method for performing thermal management on different temperature devices through a single cooling circulation system, and relates to the technical field of industrial device thermal management. The system comprises a high-temperature component, a low-temperature component, a water pump, thermostats, heat exchangers and a sensor, wherein the thermostats comprise a thermostat 1 and a thermostat 2, and the heat exchangers comprise a heat exchanger 1 and a heat exchanger 2. One water pump, two heat exchangers and two thermostats are adopted. The temperature needed by operation of a high-temperature component is reached as soon as possible in the starting stage through short circuit of the heat exchangers, the opening degree of the thermostats 1 is adjusted to reduce the flow of a loop 2 and increase the flow of a loop 1, and cooling water passes through the heat exchangers to deal with the situation that the water temperature of an outlet of the high-temperature component is high. When the flow of the loop 1 is increased, the flow of a loop 4 and the flow of a loop 5 are increased synchronously, so that heat dissipation of a low-temperature component is facilitated. In conclusion, flow adjustment and distribution of different pipelines are achieved, and then the heat stability of operation of two devices with different temperature grades under different working conditions is guaranteed.

Description

technical field [0001] The invention relates to the technical field of thermal management of industrial devices, in particular to a system and method for thermal management of devices with different temperatures by using a single cooling cycle system. Background technique [0002] In many industrial practices, thermal management is the key to maintaining the stable operation of equipment or product systems, such as lithium batteries, fuel cells, automobile engines, etc. In general, a cooling cycle system can only achieve a device or system that maintains a temperature level For thermal management systems with multiple temperature levels, it is generally necessary to set up multiple relatively independent cooling loops. Fuel cell systems are typical thermal management systems with two temperature levels. For low-temperature proton exchange The operating temperature of membrane fuel cells is generally above 60°C, most of them are at 70-90°C, and some work at above 100°C. For h...
