Description

Technical Field

[0001] The utility model belongs to the field of automobile oil cooler performance testing, in particular to an automobile oil cooler testing platform. Background Art

[0002] The oil cooler is a device that accelerates the heat dissipation of lubricating oil to keep it at a lower temperature. In high-performance, high-power reinforced engines, due to the large heat load, an oil cooler must be installed; the oil cooler is arranged in the lubricating oil circuit, and its working principle is the same as that of the radiator; Fig. 9 As shown, the structural principle of the oil cooler is demonstrated. By setting a low-temperature fluid channel and a high-temperature fluid channel in the shell, the high temperature in the high-temperature fluid channel is conducted through the heat exchange principle to achieve oil cooling.

[0003] The oil cooler needs to be tested before leaving the factory; in the prior art, water and high-temperature liquid are mainly passed through the product through a heating box, a cooling water tank and a pipeline pump. During the test, the temperature of the heating box and the cooling water tank is controlled, and the size of the opening of the ball valves of the hot pipeline and the cooling pipeline is manually opened to control the flow of each. The flow meter, temperature sensor and pressure sensor are used to read the corresponding data, and the flow rate of the product at different temperatures and pressures, the heat exchange rate and other product performance are calculated. The above scheme has the following disadvantages: (1) Manual placement of parts and manual opening and closing of pipeline valves to control the flow rate are inefficient; (2) Manual testing is labor-intensive and easily causes the risk of scalding; (3) Due to the heat loss of the pipeline and the large temperature fluctuation, the temperature time required for the test takes a long time to reach or is difficult to reach, and the test accuracy is low. Therefore, in response to the above problems, the present technical scheme provides an automotive oil cooler test bench. Utility Model Content
