Problems solved by technology
[0004] The existing air duct test devices for coolers and heaters have the following problems: 1. The air duct is simple, the length is short, and the cross-sectional area of the connecting section changes greatly, which increases the unevenness of air flow and flow resistance, and the design and manufacture are difficult. There are defects; 2: The test device is open, and the waste heat of the air after the test cannot be recycled. Sometimes the air temperature after the test is still relatively high, and direct discharge causes environmental pollution and waste of resources; 3: The overall accuracy of the measurement system is low

Description
technical field [0001] The invention belongs to the technical field of thermal performance testing devices, relates to a testing device for air cooling and heating equipment, and particularly relates to a fully enclosed testing device for thermal performance of an air cooler and an air heater. Background technique [0002] At present, large-scale projects such as nuclear power, wind power, military industry, atomic energy, and aerospace are developing rapidly, and the above large-scale projects all have coolers and heaters. The coolers are used for heat dissipation, and the heaters are used for heating. , The performance of heat exchange directly affects the quality of the above large-scale projects. Therefore, strict performance testing must be carried out before the installation and use of coolers and heaters. [0003] Existing air coolers and air heaters have only small or open systems, which in turn include an air inlet section, a heating section, a front measurement sec...
