[0002] The high temperature ageing test box is mainly used for providing high temperature environment to satisfy the user to carry out ageing test to the product under high temperature environment. The high temperature ageing test box generates heat through the heater, heats the box, and brings the heat to the box through the internal air circulation system, so that the temperature distribution in the box is uniform.

[0003] In the current ageing test box, the high temperature airflow is circulated through the air blower. However, in the process of air flow circulation, the air blower is usually arranged in a circulating channel. In the process of working of the air blower, the air flow is sucked in and the flow rate of the air flow is increased through centrifugal force inside, so that the high-speed air flow is sprayed out of the outlet. However, since there is still a large space between the air blower and the channel, some air flow flows in the space. Therefore, the air flow conveying efficiency of the test box in the current technology is not high. Therefore, the ageing temperature in the test box cannot be guaranteed without increasing the power of the air blower. Only by increasing the power of the air blower can the flow of high temperature air flow be improved, and the temperature in the test box and the constant temperature can be maintained.

[0026] Specifically, as shown in Figures 1-4 The utility model discloses an example provides a high temperature ageing test chamber, be provided with air supply channel 210, return air channel 220 and pass through the air channel 230 in the test space 101 for the product to carry out high temperature ageing test, be provided with the partition 231 that the pass through the air channel 230 is divided into two mutually independent first section 232 and second section 233 in the pass through the air channel 230, wherein the air outlet of air blowing assembly 300 is set on the partition 231 and is towards first section 232, and the air inlet of air blowing assembly 300 is set in second section 233, so that in the process of air blowing assembly 300 air exchange, the air flow in second section 233 and return air channel 220 can be fully extracted and then is blown along the air outlet, and in the process, avoid the air flow to flow into air supply channel 210 without passing through air blowing assembly 300, thereby improve the efficiency of air supply, can improve the flow velocity of air flow, ensure that test space 101 can provide air flow with high temperature in time, thereby ensure that the temperature of test space 101 remains stable.
