The Function of the High and Low Temperature and Low Pressure Test Chamber

The low-pressure testing within the high and low temperature low-pressure test chamber is a crucial part of product testing. Low-pressure testing can simulate environments with low atmospheric pressure, such as high altitudes, and is used to test and evaluate the performance and reliability of products. The following are the main roles of the low-pressure testing in the test chamber for product testing:

Thermal rise of heat dissipation products increases with the decrease in atmospheric pressure: Some heat-generating products in electrical and electronic devices consume a portion of electrical energy to convert it into heat, causing the product to heat up and rise in temperature. In low-pressure environments, as the atmospheric pressure decreases, the thermal rise of the heat dissipation products will increase, which may lead to phenomena such as reduced product performance or unstable operation.

2. The Impact of Low Pressure on Sealed Products: During low-pressure tests, the formation of pressure differences due to atmospheric pressure changes can affect sealed products. For sealed products, their shells will bear this force, potentially causing deformation of the shell and破裂 of the sealing parts, leading to product failure.

3. The Impact of Low Pressure on Electrical Performance: As altitude increases, air pressure decreases. However, under low-pressure conditions, local discharge phenomena often occur near electrodes with strong electric fields, known as corona. More severely, air gap breakdown may occur. This means the normal operation of the equipment is disrupted.

Therefore, low-pressure testing is crucial for evaluating a product's performance and reliability, as it aids designers in identifying and resolving potential issues, ensuring the product operates smoothly under various conditions.
