Automobile radiator pressure pulse test platform

Abstract

The invention discloses an automobile radiator pressure pulse test platform comprising a hydraulic pump station, a high temperature oil pump station, a test controller, an upper computer and a test platform body, wherein the test platform body comprises a hydraulic loading device and a high temperature oil loading device; the hydraulic pump station is connected with the hydraulic loading device to form a hydraulic loading mechanism; and the high temperature oil pump station is connected with the high temperature oil loading device to form a high temperature oil loading mechanism. With the adoption of the automobile radiator pressure pulse test platform, a fatigue performance test at the room temperature can be carried out on a radiator test piece, and a simulated condition fatigue test at high temperature can be carried out on radiators at the same time by additionally installing a heating device and utilizing servo hydraulic cylinders and drive hydraulic cylinders to realize single cylinder loading and multiple cylinder loading to the test piece. The automobile radiator pressure pulse test platform can be used for the fatigue test of the radiator test piece and can be also used for the fatigue test of parts such as an automobile heat exchanger, and function diversification is realized.

Description

technical field [0001] The invention relates to a pressure pulse test bench, in particular to a pressure pulse test bench for an automobile radiator. Background technique [0002] Car radiator, commonly known as car water tank, is an indispensable and important part of car engine cooling system. The car radiator consists of three parts: the radiator core for cooling, the water inlet chamber and the water outlet chamber. The coolant flows in the radiator core, and the air flows through the radiator core at a high speed. The coolant and the air exchange heat through the radiator core, so as to achieve the purpose of heat dissipation and cooling. [0003] The performance of the radiator directly affects the heat dissipation effect, power, economy and reliability of the car engine, and even the normal work and driving safety. The radiator is usually located at the windward part of the front end of the car, and the working conditions are harsh. It not only has to withstand wind...

Problems solved by technology

However, in the existing test devices for testing the fatigue characteristics of radiators, it is difficult to test the fatigue life of radiators in high-temperature environments, and it cannot truly reflect the state of radiators in actual working conditions. The test results are different from the performance of radiators in real working conditions. certain difference
