The invention has simple components, simple operation, low cost, little external interference and reliable test results.

Description

technical field [0001] The invention relates to the field of test devices, in particular to a convection cooling heat exchange test device. Background technique [0002] Various structural components used in aviation and aerospace must not only meet a certain rigidity and strength bearing function, but also meet a good heat dissipation function. The lattice structure is expected to meet the heat-proof and load-bearing functions of the specific structure of the aerospace vehicle at the same time. As a new type of structure in recent years, the research on the law of flow and heat transfer of lattice structure is very limited. Therefore, it is of great significance to provide a heat exchange device to study the heat exchange performance of different lattice structures. Convective cooling heat transfer is the most widely used heat transfer method. [0003] Currently, there are few simple and effective devices to study convective heat transfer. Some existing experimental dev...
