Heat management control system and method and device for controlling branch circulation loops

The invention provides a heat management control system and a method and device for controlling branch circulation loops. The heat management control system is applied to hybrid power assembly tests and comprises the device for controlling the branch circulation loops, a first water tank and a water pump, at least two branches are connected to a water outlet header pipe of the water pump, each branch is provided with a throttle valve and a heat-management-required device, and therefore one branch circulation loop is formed by the throttle valve on each branch, the heat-management-required device on the branch, the water pump on a master and the water tank on the master. In the heat management control system, the only one water pump can be allocated, the heat-management-required devices are connected to the branches of the water pump, and the multiple heat-management-required devices can be managed through the one heat management control system. Compared with the prior art, the integrated heat management control system has the advantage that the occupied area is saved. In addition, due to the fact that the heat management control system does not require multiple water pumps, the device cost is also saved.
