Embodiment Construction

[0042] In order to solve the problem of low accuracy of the thermal shock test of the radiator in the prior art, the embodiment of the present invention controls the ambient temperature of the radiator to the preset ambient temperature, and controls the heater to heat the coolant to The preset coolant temperature, according to the preset ambient temperature and the preset coolant temperature, controls the flow rate of the coolant flowing into the radiator, obtains the temperature of the radiator, and then according to the temperature of the radiator temperature, adjust the coolant flow into the radiator accordingly and determine whether to turn on the fan, then detect whether the radiator leaks, and determine the thermal shock resistance of the radiator according to the detection results. Since the cooling control of the radiator is realized through the fan and the ambient temperature, it is closer to the real working conditions that cause thermal shock than the method of direc...

Abstract

A radiator hot and cold shock-testing method, device and system are provided; the method comprises the following steps: controlling the ambient temperature, to where the radiator is located, to be ata preset ambient temperature, and controlling a heater to heat a cooling liquid up to a preset cooling liquid temperature; controlling the cooling liquid flow entering the radiator according to the preset ambient temperature and the preset cooling liquid temperature; obtaining the temperature of the radiator; correspondingly adjusting the cooling liquid flow entering the radiator according to theradiator temperature and determining whether to open a fan or not, wherein the relative relation between the fan and the radiator is same with the mounting relative positions on a vehicle, and the fanis used for diffusing the heat of the cooling liquid entering the radiator; detecting whether the radiator is leaking or not, and determining the hot and cold shock resistance property of the radiator according to the detection result. The method and device can improve the radiator hot and cold shock-testing accuracy.

Description

technical field [0001] The invention relates to the field of vehicle component testing, in particular to a thermal shock testing method, device and system for a radiator. Background technique [0002] The water tank, also known as the radiator, is an important component of the cooling circuit of the water-cooled engine. Due to the large specific heat capacity of water, the temperature of the cooling water does not rise much after absorbing the heat of the cylinder body, so the heat of the engine can form a liquid circuit through the cooling water, use water as a heat carrier to conduct heat, and then flow into the radiator through a fan The water dissipates heat and forms cooling water to flow into the cylinder block of the engine again, so as to avoid the excessive temperature of the engine. In the case of low water temperature such as winter, the circulation of water in the water tank can also be stopped to prevent the engine temperature from being too low. In some cases...
