Problems solved by technology

In addition, traditional experiments use water-cooling or air-cooling for cooling, and the thermal resistance of the cold side is separated by the separation method to obtain the heat transfer coefficient of the hot side. This method will introduce the error of the measurement of the cold side and the calculation error of the separation method into the heat si...

Abstract

A capability tester based on exchanger fin cell belongs to energy sources and chemical industry technology field. The test equipment makes up by oil pressure ductwork, constant temperature oil melt, test part, heat preservation water tank and data test/ collection system. Test fin, test frame, first and second red-copper base plants, first and second film heating plants, first and second adiabatic frames, first and second adiabatic plants, first and second sealed pillows, clamp, oil intake pipe, oil outlet pipe, thermocouple, intake platinum resistance, outlet platinum resistance, first and second leading press pipes, press intake sensor, press outlet sensor and digital power dial make up into the test part. The test part reduces the heat balance error by inside the heat preservation water tank and uses the electric power to offer quantity of heat. It adopts mono-layer fin as the test object to avoid the test error of the asymmetry of the matter in the exchanger with high test precision, simple manipulate and low cost.

Description

Technical field [0001] The invention relates to a test device, in particular to a performance test device based on a heat exchanger fin unit, and belongs to the technical field of energy and chemical engineering. Background technique [0002] There are many manufacturers of heat exchangers at home and abroad, and the measurement of heat exchange and resistance of heat exchangers is a relatively common test method. The traditional test is to study the integral heat exchanger composed of multi-layer heat exchange units, and measure the flow and heat transfer characteristics of the enhanced heat transfer surface by water cooling or air cooling. This test method is more common, but it also brings some disadvantages. Take a plate-fin engine oil cooler as an example. The heat exchanger is formed by brazing multiple layers of chips. The engine oil flows through each layer of the chip of the cooler, and the cooling water flows through the outside of the chip in the reverse direction to e...
