Temperature control system and method for test bench

Abstract

The invention discloses a temperature control system and method for a test bench, which are used for controlling the temperature of a tested object on a test bench. The system comprises an internal circulation cooling liquid pipeline and an external circulation cooling liquid pipeline communicated with the internal circulation cooling liquid pipeline. The external circulation cooling liquid pipeline is composed of a basic circulation pipeline and a temperature regulation and control pipeline. A flow monitoring end and a pressure monitoring end are arranged on the basic circulation pipeline; a temperature monitoring end is arranged on the temperature regulation and control pipeline; an electric control unit is arranged in the temperature control system; and the electric control unit establishes flow regulation, pressure regulation and temperature regulation of the temperature control system through real-time monitoring of the flow monitoring end, the pressure monitoring end and the temperature monitoring end and issuing of corresponding regulation and control instructions. According to the temperature control system and method for the test bench, the control precision and the cooling and heating capacity of temperature control are improved, meanwhile, automatic liquid supplementing and liquid pumping of the system can be achieved, and the application range of temperature control is widened on the whole.

Description

technical field [0001] The invention belongs to the field of test benches for automobile engines, fuel cells and motors, and in particular relates to a temperature control system and method for test benches. Background technique [0002] In engine, motor and fuel cell assembly workshops or laboratories, in order to ensure that each unit can be qualified off the assembly line, it is necessary to test the tested parts after the assembly is completed. During the test process, heat is generated due to the movement of the tested object, so it is necessary to control the temperature of the tested object to prevent damage to the tested object during the test. At this time, a suitable temperature control device and temperature control method are required for the application Test bench. [0003] Although the previous temperature control devices have the function of temperature regulation, the use of temperature control devices is limited due to reasons such as low temperature contro...

AI Technical Summary

Problems solved by technology

[0003] Although the previous temperature control devices have the function of temperature regulation, the use of temperature control devices is limited due to reasons such as low temperature control accuracy, poor cooling and heating capabilities, and small temperature control range.

And it will indirectly affect various parameters of the test; at the same time, the previous temperature control device has limitations in the communication and flow control of the integrated alarm signal and the host computer
