[0029] The high accelerated life test apparatus 100 according to an embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the high accelerated life test apparatus 100 according to an embodiment of this application includes: a test chamber 10, a humidity control unit 20, and a pressure control unit 30.

[0031] Specifically, the experimental chamber 10 is equipped with an experimental cavity 11a, and a humidity control unit 20 is connected to the experimental cavity 11a. The humidity control unit 20 can controllably input gases with different humidity levels into the experimental cavity 11a. The pressure control unit 30 is connected to the experimental cavity 11a and is used to automatically control the pressure inside the experimental cavity 11a.

[0032] In other words, such as Figure 1As shown, the high-accelerated life testing apparatus 100 according to an embodiment of this application is mainly used for accelerated life testing of electronic products. The high-accelerated life testing apparatus 100 mainly includes a test chamber 10, a humidity control unit 20, and a pressure control unit 30.

The humidity control unit 20 and the pressure control unit 30 are respectively connected to the test cavity 11a. The humidity control unit 20 can controllably input gases of different humidity levels into the test cavity 11a. These gases include gases with 0% humidity (i.e., dry gas), low humidity gas, medium humidity gas, and high humidity gas. The pressure control unit 30 can automatically control the pressure within the test cavity 11a when adjusting the humidity, ensuring that the air pressure within the test cavity 11a does not change.

[0033] According to the high accelerated life test apparatus 100 of the application embodiment, when adjusting the humidity in the test chamber 11a, for example, when decreasing the humidity in the test chamber 11a, the humidity adjustment unit 20 can input dry gas into the test chamber 11a, and at the same time, the pressure control unit 30 will discharge the same amount of the original gas in the test chamber 11a as the input dry gas, thereby ensuring that the pressure in the test chamber 11a remains constant; correspondingly, when increasing the humidity in the test chamber 11a, the humidity adjustment unit 20 can input high humidity gas into the test chamber 11a, and at the same time, the pressure control unit 30 will discharge the same amount of the original gas in the test chamber 11a as the input high humidity gas, thereby ensuring that the pressure in the test chamber 11a remains constant.

[0034] Therefore, the high accelerated life test apparatus 100 provided in this embodiment, through the coordinated operation of the humidity adjustment unit 20 and the pressure control unit 30, can ensure that the pressure in the test chamber 11a remains constant during the humidity adjustment process, thereby effectively avoiding the interference of pressure fluctuations on the test results, and thus effectively improving the reliability and accuracy of the test results.

The second gas source can be a high-pressure gas cylinder, such as a high-pressure nitrogen cylinder, and the nitrogen can be high-purity nitrogen. The second gas source can supply dry gas to the pressure controller.
