Abstract

The invention discloses a test device for verifying the cold and heat cycle performance of an engine radiator. The test device comprises a main loop and a control system, wherein the main loop is used for a test for the cold and heat cycle performance of the radiator, and the control system is used for controlling the operating condition of the whole device. The main loop comprises a hot water circulation loop and a cold water circulation loop, and the outlets of the cold water circulation loop and the hot water circulation loop are respectively connected with the inlet of the radiator. The outlet of the radiator is respectively connected with inlets of the cold water circulation loop and the hot water circulation loop, and the control system respectively controls and connects the cold water circulation loop and the hot water circulation loop. The test device has simple structure and low cost, and can fully detect the cold and heat cycle performance of the radiator. The test device is suitable for carrying out the test for the cold and heat cycle performance of any engine radiator.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a device for testing the performance of a vehicle engine radiator, in particular to a test device for verifying the cooling and heating cycle performance of the engine radiator. Background technique [0002] At present, the radiator assembly of an automobile engine is usually composed of flat tubes, fins, main boards, side plates, sealing rings, upper and lower water chambers, water discharge switches, and radiator covers. The radiator and engine water jacket are combined to form an airtight The container realizes the functions of water storage and heat dissipation of the radiator. Since the start and stop of the engine will cause the antifreeze inside the radiator to alternate between hot and cold cycles, and the above-mentioned components are made of aluminum, rubber and plastic, and the expansion coefficients of these materials are inconsistent. , will cause the loss of the crimping ...
