The thermal shock test chamber is mainly used in the metal, plastic, rubber, electronics and other materials industries. It is used to test the structure of materials or composite materials, and tolerate the degree of transient high temperature and extremely low temperature in an instant. Chemical changes or physical damage caused by thermal expansion and contraction in the shortest time; The rapid temperature change test chamber is a temperature change with a temperature change rate generally greater than 5 ° C. The test chamber is widely used for high and low temperature stress screening in aviation, electronics, instrumentation, electrical and electronic products, medicines, materials, parts and complete machines. Low-temperature storage, constant temperature, and other adaptive tests; in order to analyze and evaluate the performance and behavior under the environmental conditions in the test. The rapid test chamber consists of a test chamber, a refrigeration system, a temperature control system, an air conditioning system, and a safety protection device. Temperature changes are also divided into average rate of change and rate of change of uniform rate; High and low temperature test chamber (or constant temperature and humidity test chamber), mainly used in industrial products, such as: aerospace, electronic and electrical, automotive motorcycles, ship weapons, colleges and other industries, by creating high temperature and low temperature environment in the work room, thus Perform high and low temperature weather resistance tests. So, what is the difference between the three? 1. Although the same is true for testing the performance of products at high and low temperatures, the time it takes for temperature changes is different. Usually, the conventional high and low temperature test chamber is heated at 3 degrees per minute and is cooled by 1 degree per minute. However, the thermal shock test chamber quickly completes the conversion from high temperature to normal temperature or normal temperature to low temperature within a few seconds, thereby achieving the product. A more cruel test. The rapid temperature change is a temperature change test between the two. 2. The prices of high and low temperature test chambers, thermal shock test chambers and rapid temperature change test chambers are also different. Different performances and different prices are relatively higher than the price of thermal shock test chambers. The price of the rapid temperature change test chamber is also much higher than that of the high and low temperature test chamber. If the temperature change is straight, then the price is comparable to the thermal shock test chamber. When the temperature change rate reaches 10 °C or more, and the change is straight. The price is also higher than the thermal shock test chamber of the same volume studio. 3. The appearance is also different. The high and low temperature test chamber and the rapid temperature change test chamber are generally one box type, that is, one working chamber, which is above the equipment. The thermal shock test chamber is also divided into three boxes and two boxes, with a high greenhouse, a low greenhouse or a conversion room. 4. Generality. It can be seen from the above analysis that the rapid temperature change test chamber can replace the high and low temperature test chamber, but the high and low temperature test chamber cannot replace the rapid temperature change test chamber. Of course, the thermal shock test chamber can not replace the other two, because the temperature change of the high and low temperature test chamber and the rapid temperature change test chamber is a gradual process, and the thermal shock test chamber is a process of sudden temperature change, for products or materials. The temperature effects are different. With the simple introduction of the three products through the test, the user can compare and choose the right product when purchasing the equipment. It is the basic principle to purchase the product to meet the test requirements. Otherwise, the high utilization and low utilization is a waste of equipment.
