System for testing heat-transfer performance of gas-water-oil heat interchanger

Abstract

The invention relates to a system for testing heat-transfer performance of a gas-water-oil heat interchanger, and is composed of a steady air system, a cold water system, a hot water system and a oil system. The steady air system: a voltage-stabilizing case output end is connected with inlets between the first steady air flow gauge and the first steady air pneumatic butterfly valve or the second flow gauge and the second steady air pneumatic butterfly valve and high-pressure centrifugal fan, wherein, steady air bypass electric control valve is connected between the inlet and the outlet of the high-pressure centrifugal fan; the hot water system: an expansion water tank, an electric heater water tank and an outlet are connected to the water pump, and water enters into the heat interchanger to be measured through the bypass of the electric three-way valve, the water flow gauge and the electromagnetic valve, thereby forming a closed loop system; the cold water system: compared with the hot water system, the system does not have an expansion water tank; the oil loop system is a open and close type circulating system: the outlets of the expansion fuel tank and the fuel-tank are connected to the oil pump, oil enters into the heat interchanger to be measured through the bypass of the electric three-way valve, the oil flow gauge and the electromagnetic valve, thereby forming a closed circulation for testing the heat exchange performance of the oil-water, oil-gas heat interchanger.

Description

technical field

[0001] The invention relates to a heat transfer performance test system of a heat exchanger, in particular to a device capable of simulating a heat transfer device to conduct a heat transfer performance test of heat exchanger air-water-oil under actual working conditions. Background technique

[0002] At present, to detect the heat transfer performance of gas-gas heat exchange equipment, the method of small sample test is usually used and the test is not simulated under the working conditions of the actual use of the heat exchange equipment. However, with the development of society, energy saving and consumption reduction, reduction Automobile exhaust pollution, etc., the heat transfer performance and resistance performance test requirements of the radiator tank and oil cooler in the locomotive often need to be tested under actual operating conditions. Therefore, a system that can Considering the flow, temperature, pressure, data acquisition and human interfe...
