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

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of thermal management of hybrid electric vehicles, in particular to a thermal management control system and a branch circuit control method and device. Background technique [0002] In the existing hybrid powertrain bench test, the thermal management control systems of different devices that require thermal management (such as engines, motors, and other devices) are independent of each other, and are controlled by a separate set of independent thermal management systems. The system manages its heat, which requires a water tank and a water pump for each independent heat management control system. So-called thermal management not only cools the device, but also heats it up if necessary. [0003] The existing method of setting different thermal management control systems for different devices such as engines and motors needs to arrange multiple sets of thermal management control systems in one laboratory, and ...

Problems solved by technology

[0003] The existing method of setting different thermal management control systems for different devices such as engines and motors needs to arrange multiple sets of thermal management control systems in one laboratory, and the setting of multiple sets of thermal management control systems will take up more time. laboratory area

Moreover, since each thermal management control system needs to correspond to a water pump and a water tank, the equipment cost is relatively high
