[0002] High-temperature test chambers are essential testing equipment in the fields of aviation, automobiles, home appliances, scientific research, etc. They are used to test and determine the parameters and performance of electrical, electronic and other products and materials after high-temperature or constant-temperature testing. The air supply mechanism consists of a fan that can operate continuously at high temperatures and a special air duct, which makes the temperature in the workroom uniform, thereby enabling the performance of products to be tested in a specific temperature environment.

[0003] Chinese utility model patent announcement number: CN214794543U, discloses: a high-temperature test chamber air supply structure, the high-temperature test chamber air supply structure, the high-temperature test chamber air supply structure, by providing an air inlet mechanism, a top shell and an electric heating plate, etc. Before the device is used, the outside air enters the box above the partition through the air inlet plate, and the box can be sealed by closing the electric control valve. At this time, it is only necessary to turn on the electric heating plate and use the heat generated by the electric heating plate to transfer the heat to the annular heat conduction plates on the upper and lower sides of the partition, thereby heating the inside of the box. However, the high-temperature test chamber air supply structure is not convenient for controlling the wind speed and direction in the air inlet mechanism when supplying air, and the high-temperature test chamber air supply structure is not designed with a dust-proof structure and zoned air inlet, which easily leads to higher or lower temperatures in a single area, and has poor practicality.

[0019] 2. The air supply structure of the high-temperature test chamber can divide the inside of the high-temperature test chamber into three areas through the design of the partition. Combined with the design of the three air supply components, the fan and the wind wheel, air can be supplied to different areas according to actual usage to avoid high temperature in a single area and improve its practicality. When air supply is needed, the fan can be turned on first to drive the wind wheel to rotate.
