Problems solved by technology

However, the current improvement schemes for the channel structure are basically based on the results of numerical simulations, and the actual observation of the flow field shape using the channel visualization device is rare, so the visualization of the flow field information in the channel of the PCHE channel structure cannot be realized

Description

technical field [0001] The invention belongs to the heat transfer field of heat exchanger internal flow field optimization, and relates to a flow field visualization device for a channel flow field of a printed circuit board heat exchanger. Background technique [0002] Heat exchangers are widely used in coal-fired power plants, nuclear reactors, electronic technology, aerospace, and automobiles. For heat exchange systems that require high temperature, high pressure, and large heat exchange area, the heat exchange efficiency of conventional shell-and-tube heat exchangers Low, need to occupy too much space and can not meet the design requirements. In 1985, the British Heatric Company proposed a compact heat exchanger design with excellent heat transfer performance and high efficiency - printed circuit board heat exchanger (PCHE). The heat exchanger can meet the requirements of high temperature, high pressure, less leakage, excellent heat transfer efficiency, and high heat tr...
