What is the difference between the three-Cabinet-type and the hanging basket type of the thermal shock Test Chamber?

The thermal shock Test Chamber is used to test the structure and complex materials of products, which can cycle extremely high-low temperatures instantaneously. Can withstand the level, test chemical changes or physical damage caused by thermal expansion and contraction in a short period of time. Objects used include necessary test equipment for testing material structures or composites in the metal, plastic, rubber, electronics and other materials industries. Composite materials can be used as a basis or reference for product improvement.

There are two types of thermal shock Test Chambers , one is a three-Cabinet-type, and the other is a hanging basket type thermal shock Test Chamber. Some customers don't know which one to buy when purchasing this thermal shock Test Chamber. So is the Three-Chamber thermal shock Test Chamber better than the hanging basket thermal shock Test Chamber ? Actually, it's not better, the two have different testing procedures, and the end goal is the same.

From a stricter point of view, the temperature conversion of the hanging blue thermal shock Test Chamber is faster than that of the three-chamber Temperature Test Chamber, and the test conditions are more severe. However, the two are different. The hanging basket thermal shock Test Chamber is also a two-box thermal shock Test Chamber. The working principle of the two-box thermal shock testing machine: the test box generates a high-temperature environment (60°C~200°C) and a low-temperature environment (-10°C~-80°C) respectively through the heating system and the cooling system of the unit. According to the relevant requirements of the impact test, put the tested product into the load basket of the designated greenhouse, and when the two greenhouses reach the preset temperature and stabilize, the load basket is driven by the transmission mechanism to realize the test component in the basket between the high-low chambers. move. During the moving process, the high-low greenhouses are connected, and the components under test also enter another greenhouse from a high or low temperature state, so a large amount of cooling and heating loads will be brought in, and the unit must quickly return to the predetermined temperature of each greenhouse through the refrigeration system or heating system. When the temperature of the greenhouse where the component under test is located remains stable for a long time, the load basket is pulled in the opposite direction through the transmission mechanism, and the component under test is brought back to the original greenhouse. It must also quickly return to the predetermined temperature. Repeat the above operation to complete multiple temperature cycle shock tests. The advantage is that the high-low temperature impact temperature is fast, but the recovery speed is slow, and the low temperature area and the high temperature area need to be recooled during the second impact.

Three - box thermal shock Test Chamber, built-in pre-cooling area, pre-heating area and test area, these three areas are independent. The three boxes are switched by valve without moving the test product. When impacting at normal temperature, please use the blower to introduce the ambient temperature into the test space to eliminate heat or cool the test space, and close the damper of the high-low temperature storage tank; Connects to the Test Chamber and immediately introduces pre-stored cooling capacity into the Test Chamber. Close the low temperature and normal temperature storage tank dampers, connect the high temperature storage tank to the test box, and then immediately introduce the pre-stored heat into the test box. So as to achieve the purpose of rapid temperature change.
