System for testing heat transfer and resistance characteristics of large-size generating equipment heat exchanger

Abstract

The invention relates to a system for testing heat transfer and resistance characteristics of a large-size generating equipment heat exchanger. The system comprises a straight flow type air duct system, a circulating water system and a circulating oil system. The straight flow type air duct system inhales air, after heating, flow mixing and rectification, the air flows into the air cooling device; after heat exchange through an air cooling device tester, hot water is inputted by a water pump to a cooling tower for cooling, the cooled water is heated by an air heater to realize water temperature required by a test and then flows into a heat exchanger tester to form a temperature-controllable circulating water system; oil in an oil tank is heated, the heated oil flows into the heat exchanger tester, the oil after heat exchange flows into an oil storage tank to form the circulating oil system; the circulating water system and the circulating oil system respectively realize closed circulating and are used for testing heat transfer coefficients and resistance characteristics of the heat exchanger. The test system can test heat transfer and flow resistance characteristics of the air cooling device and an oil cooling device, can realize water cycle utilization and greatly saves resources.

Description
