Wind tunnel structure for testing heat dissipation performance

The embodiment of the utility model discloses a wind tunnel structure for a heat dissipation performance test. The wind tunnel structure comprises a shell and a mounting panel, and the shell comprises an internal containing cavity, an air inlet and an air outlet so as to form a through-flow air channel simulating heat dissipation airflow; the installation panel is detachably arranged on one side of the air inlet of the shell, and the installation panel is provided with a through-flow hole and an installation interface which are respectively matched with a power device to be tested. Based on the characteristic that the mounting panel is detachably connected with the shell, the mounting panel corresponding to the to-be-tested power device can be selectively configured. Through the structural design of replacing the mounting panel, the scheme can be applied to heat dissipation performance tests of power devices of different models or specifications. The method has good compatibility and operability, and the over
