Shortly, for thermal shock test chamber, 2 zone, there is a basket inside of the thermal shock test chamber transfer from cold zone to hot zone, and vice versa. The basket should transfer to another zone within 15 seconds, the temperature in each zone should be recovered within 5 minutes.
For a thermal shock test chamber, it is used to test the capability of material structure or composite materials to withstand the continuous environmental changes between extremely high and low temperature during a short time, and therefore understand the chemical changes or physical damages caused by expansion and contraction in the shortest possible time.
In order to achieve quick temperature change, the refrigeration system must to very powerful. So normally, the thermal shock test chamber in big size.
Sometimes, considering the shipment problem, we have to build the chamber in horizontal type. But, what’s the internal structure of a 2 zone thermal shock test chamber?
Normally, the basket will be with wheels for transfer movement, the transfer will be driven by an air cylinder, that is the reason normally the compressed air is required for installation of a thermal shock test chamber. Different environmental chamber manufacturers have their own design, for our design, the structures as below:
