Mobile phase change heat transfer and flow performance test device

Abstract

The invention provides a mobile phase change heat transfer and flow performance test device, which consists of a multi-layer frame, a phase change medium loop, a test section, a cooling / heating medium loop and a control system. All components of the test device are all placed in the multi-layer frame by category, universal wheels are mounted at the bottom of the multi-layer frame, so that the test device can realize overall directional movement, the operation is convenient, and the structure is compact. By changing the test section, the test device provided by the invention can be applied to multiple types of heat transfer structures, is especially suitable for micro-channel phase change heat transfer performance test and visualized test, and has strong functionality. During visualized phase change test, the test device is externally connected to a high-speed photographic instrument for image acquisition. When the test device is applied to heat transfer performance testing, the measurement signals of multi-channel temperature, flow, pressure and other key parameters are automatically acquired, processed and analyzed by the control system, the test result is displayed through an operating console screen, and is accurate and visual, and the test process is efficient and intelligent.

Description

technical field [0001] The invention relates to a test device for phase change heat transfer and flow performance. Background technique [0002] The rapid development of industry has put forward higher and higher requirements for large-capacity equipment. The performance of heat exchange equipment directly affects the economic benefits of the equipment. In particular, engineering equipment in the aerospace field needs to use small-sized equipment due to limited space and power. , Lightweight compact heat exchanger. Research on enhanced heat transfer elements and high-efficiency heat exchange equipment can not only improve the comprehensive utilization of heat exchange system energy and reduce unnecessary energy consumption, but also a topic that must be solved in the development of modern industry. Using experimental methods to study the heat transfer performance of heat transfer elements and heat exchange equipment is very intuitive and has the most reference value. Howev...
