Test device for engine thermal management system

Abstract

The invention discloses a test device for an engine thermal management system. The test device comprises an engine, an engine thermal management system, a plurality of sensors, an air channel, a cooling fluid pipeline, an air pipeline, a thermal management system motor driving device, data acquisition equipment and an engine test rack. By the test device, the performance of the engine thermal management system can be tested, the engine is loaded by using a dynamometer to provide actual working conditions for the thermal management system, the air channel, a windward fan, and an intercooler, a heat radiator and a fan which are arranged on an adjustable bracket are used for simulating cooling and heat transferring conditions inside a power cabin, operating characteristics such as flow, pressure and the like of all accessories of the engine thermal management system are measured by using the high-accuracy data acquisition equipment, and the heat exchange capacity of the heat radiator and the intercooler and the influence of the thermal management system on the performance of the engine can be quantitatively analyzed, so that the performance of the thermal management system can be comprehensively evaluated. By the test method, an important test basis is provided for product development of the thermal management system.

Description

technical field [0001] The invention relates to an engine thermal management test device, in particular to an engine thermal management system test device. Background technique [0002] With the continuous improvement of modern engine performance, the heat load of the engine is getting higher and higher, and the traditional cooling system has been difficult to meet the increasingly stringent engine power, economy and emission requirements. The traditional cooling system often uses mechanically driven fans, water pumps and paraffin thermostats, which are prone to overheating under extreme conditions and overcooling under partial loads. The cooling system is inefficient, high energy consumption, and seriously affects the engine. emissions and fuel consumption. In this context, the concept of thermal management is proposed, that is, from the point of view of system integration and overall, the relationship between heat, engine and even the whole vehicle is considered as a ...

AI Technical Summary

Problems solved by technology

The engine cooling system designed by this design method is inefficient and expensive, and consumes a lot of time and capital costs

Although the current development of computer technology has greatly shortened the research and development cycle, the simulation accuracy of the model still needs to be improved, and the calculation method needs to be optimized, which cannot fundamentally replace the role of the test.

Although the actual vehicle test is effective, it takes a long time. Due to the limitation of the actual vehicle environment, it is difficult to obtain complete test data to analyze and improve the design scheme. Only experience can be used to roughly match the cooling system.

However, the wind tunnel test method used in foreign countries requires huge investment.
