Abstract

The invention relates to a radiator test bench for simulating a highland high-altitude environment. The test bench comprises a high-altitude simulation cabin (1), a circulating system (9), and a measurement and control system (12). The high-altitude simulation cabin (1) is provided with a flow measurement device (2), a rectifier (3), a radiator (5), a heat exchanger assembly (11), a rectifier (7) and a fan assembly (9), wherein the front and back of the radiator (5) are respectively connected with a front wind chamber (4) and a rear wind chamber (8). The circulating system (9) comprises a radiator heat path circulating system (6) and a heat exchanger cold path circulating system (12). The measurement and control system (10) comprises a temperature sensor, a pressure sensor, and the flow measurement device (2). The test bench is advantageous in that the test bench can simulate the heat dissipation performance of a radiator in ground and highland high-altitude environments, reduces the air flow through the circulating system (9), reduces the energy consumption, enlarges the application range, and is high in practicality and universality.

Description

technical field [0001] The invention belongs to the field of radiator performance test devices and relates to other liquid test equipment. Background technique [0002] Radiators are widely used in aerospace, air-conditioning manufacturing, automobile manufacturing and other industries. The heat dissipation performance of the radiator is one of the main performances of the radiator. The heat dissipation performance of the radiator is usually obtained by wind tunnel test. At present, the wind tunnel test of the heat dissipation performance of the radiator has many deficiencies, such as the performance of the radiator that can only simulate the ground environment . Contents of the invention [0003] The purpose of the invention is to realize the simulation of heat dissipation performance of radiators in ground, plateau and high-altitude environments, utilize circulating air, reduce air flow, and save energy consumption. [0004] The technical solution of the present invent...
