Description

Technical Field

[0001] The present application relates to the field of thermal management technology for pure electric commercial vehicles, and in particular to a thermal management universal integrated module and a thermal management assembly. Background Art

[0002] The thermal management system of new energy vehicles must not only meet the heating and cooling needs of the passenger compartment, but also manage the temperature of the power battery, drive motor, and various controllers. There are many components to be cooled / heated and the required temperatures are different. The existing thermal management system has separate and independent arrangements for the electric drive battery water pump, heat exchanger, etc., and is connected through multiple valves and pipes to form a thermal management cycle.

[0003] With the development of thermal management technology, it is necessary to coordinate the heat transfer between the battery, electric drive, passenger compartment and the external environment and improve the efficiency of integrated thermal management. Technologies such as heat pump air conditioning and electric drive / battery waste heat utilization are applied. Existing technologies achieve waste heat utilization by adding multiple heat exchangers and valves and switching circuits, which further increases the number of parts and design and development costs.
