Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] figure 1 and 2 Schematically shows a heat exchanger wind tunnel test system according to an embodiment of the present invention, including a wind-side circulation system and a water-side circulation system, both systems are provided with a tested heat exchanger 2 for installation The assembly section of the heat exchanger under test, so that the heat exchanger under test 2 can be connected to the two systems at the same time. Among them, the water side circulation system provides water circulation for the tested heat exchanger 2 to replace the refrigerant in the tested heat exchanger 2, and the air side circulation system provides the working conditions of the air side, and the heat exchange between water and air simulates the relationship between the refrigerant and the air. The heat exchange can realize the performance test of the heat exchanger. ...

Abstract

The invention discloses a wind tunnel test system for a heat exchanger. The system comprises a wind-side circulation system and a water-side circulation system, a tested heat exchanger can be connected into the wind-side circulation system and the water-side circulation system; the water-side circulation system comprises a water tank, a pump, a water-side tested heat exchanger assembly section, awater inlet temperature sensor arranged at a water inlet of the water-side tested heat exchanger assembly section, a water outlet temperature sensor arranged at a water outlet of the water-side testedheat exchanger assembly section, a liquid heater, a cooler and a flowmeter, wherein the water tank, the pump and the water-side tested heat exchanger assembly section are connected through pipes in sequence, and the water-side tested heat exchanger assembly section is connected with the water tank; the liquid heater and the cooler are arranged between the pump and the water inlet temperature sensor, and the flowmeter is connected with the water inlet or water outlet of the water-side tested heat exchanger assembly section and used for detecting the flow of the tested heat exchanger. Accordingto the wind tunnel test system, a refrigerating agent is not needed, compared with the prior art, refrigerating agent consumption is not needed, the safety requirements for the water-side circulationsystem are low, and the test temperature range is wider.

Description

technical field [0001] The invention relates to the field of heat exchanger testing. Background technique [0002] The current heat exchanger performance test system usually uses refrigerants for testing, and each test requires a large amount of refrigerant consumption, which is not energy-saving and environmentally friendly; secondly, when using certain flammable refrigerants for testing, the leakage prevention of the system And other safety requirements are high, which increases the cost of the system; thirdly, the temperature range measured by refrigerant is small, and it is usually unable to simulate low temperature or even sub-zero working conditions, and the working condition range is limited. Contents of the invention [0003] An object of the present invention is to provide a heat exchanger wind tunnel testing system to solve the above problems. [0004] According to one aspect of the present invention, a heat exchanger wind tunnel testing system is provided, comp...
