Component testing device capable of rapidly cooling by cold air and cold flow

The invention discloses a cold air and cold flow rapid cooling component testing device which comprises a refrigerating unit and a testing area, a testing frame is arranged in the testing area, a plurality of testing plates and a cover shell are arranged on the testing frame, the testing plates are connected with testing signal plates, a moving assembly is arranged on the cover shell, and the moving assembly is connected with the testing signal plates. The moving assembly is arranged on the testing frame, and the moving assembly drives the housing to be located above the testing plate; and the refrigerating unit is connected with the housing through a low-temperature hose. The device outputs low-temperature airflow, uniformly blows air to a product on a test board, enables the surface of the product on the tested board to change drastically, completes a corresponding low-temperature test, can blow air to a plurality of components in one platform and perform a low-temperature test, and compared with a traditio
