The high and low temperature test chamber is used for the reliability test of high and low temperature of industrial products. The components and materials of electronic products, automobile motorcycles, aerospace, marine weapons, colleges and universities, scientific research units and other related products are tested under high and low temperature conditions. What are the temperature ranges of the high and low temperature test chamber
At present, the range of foreign temperature test chambers is generally -73 ~ +177 ° C, or -70 ~ +180 ° C. Most domestic manufacturers are generally -70 ～ + 150 ℃, -60 ～ + 150 ℃, -40 ～ + 150 ℃. These temperature ranges can usually meet the needs of most domestic military and civilian product temperature tests, unless there are special needs, such as products installed near the engine and other heat sources, the upper temperature limit cannot be blindly increased.
Because the higher the upper limit temperature, the greater the temperature difference between the inside and the outside of the box, and the worse the uniformity of the flow field inside the box, and the smaller the available studio volume. On the other hand, the higher the upper limit temperature value, the higher the heat resistance requirements of the thermal insulation material (such as glass wool, etc.) in the tank wall interlayer, and the higher the sealability requirements of the box body, which increases the price of the high and low temperature test box.
