Multi-medium combined heat exchanger test bed

Abstract

The invention provides a multi-medium combined heat exchanger test bed. The multi-medium combined heat exchanger test bed comprises an intercooler test bed, and a water / oil heat exchanger test bed, wherein the intercooler test bed comprises an air heating system, an air circulation system, an intercooler test bed wind tunnel system, a specimen, a measurement instrument and pipelines; the water / oil heat exchanger test bed comprises a water circulation system, an oil circulation system, a heat supply system, a water / oil heat exchanger test bed wind tunnel system, a specimen, a measurement instrument and pipelines; and the intercooler test bed and the water / oil heat exchanger test bed are connected with each other through the pipeline and are controlled by a monitoring system. The multi-medium combined heat exchanger test bed can meet the requirement for performance testing of various types of heat exchangers, and can improve the single test mode of the original parts to the synchronous comprehensive test mode of the parts and the system, thereby further improving the design strength and the design level of heat radiation systems for the military special vehicles, other vehicles and engineering machines.

Description

technical field [0001] The invention relates to a heat exchanger test bench, in particular to a multi-media combined heat exchanger test bench. Background technique [0002] The heat dissipation of the vehicle system is an important indicator to measure its advanced nature, because each component and system of the vehicle has an optimal operating temperature range, and the performance indicators of the components can be guaranteed within this temperature range. At present, the research and development of the vehicle system has entered the development stage of self-development and independent innovation. Due to the lack of real vehicle test conditions and the complexity of the vehicle working environment, there is a serious lack of effective real vehicle test data. The test period is long and the data can be obtained. The reproducibility is poor, and it is impossible to provide accurate and effective real vehicle test data to the engineering design department, which seriously...

AI Technical Summary

Problems solved by technology

Domestic test benches for heat transfer performance and resistance performance of heat dissipation systems can only provide bench tests for a single heat dissipation component, such as independent tests of water radiators, oil radiators, and air-to-air coolers, etc., which can no longer meet the increasingly diverse needs. The development trend of heat exchangers, especially the performance test of compound heat exchangers

For heat exchangers with different structures and principles, separate test benches are established, which not only causes waste of equipment and energy, but also fails to solve the comprehensive test of the radiator cooling system that simulates the working conditions of real vehicles.
