Structural characteristics
Cabinet structure	Inner box material: 304# stainless steel, 1.0mm thick Outer box material: Cold plate, painted, 1.2mm thick Insulation material: Polyurethane foam + glass fiber, 100mm thick
Door	Single door explosion-proof handle
Air conditioning duct	Built-in high temperature zone, low temperature zone air room, circulating air duct and stainless steel circulating fan. Through the switching of the damper, heat and cold are evenly blown out from the inside of the air duct, and the temperature stored in the high temperature tank and low temperature tank is dissipated to the test space, thereby achieving rapid temperature alternation and uniform indoor temperature distribution.
Test lead hole	A 50mm Φ test hole is drilled and fitted with appropriate insulation components and a dedicated sealing plug.

Cooling water tower	Water circulation heat dissipation, flow rate 8 tons/hour
Transportation method	Complete machine transportation
Test material rack	2 pieces of stainless steel SUS #304 grid-type storage racks (load-bearing capacity ≤ 20kg/piece)
How it works	The pre-cooling area, pre-heating area and test area are independent of each other. The three boxes can be switched through the air door without moving the test product. When the room temperature is impacted, the ambient temperature is introduced into the test space through the blower to remove the heat or cold in the test space. At the same time, the air doors of the high and low temperature slots are closed. When the low temperature is impacted, the air doors of the high and normal temperature slots are closed, and the low temperature slot is connected to the test box, and the pre-stored cold energy is instantly introduced into the test box. When the high temperature is impacted, the air doors of the low and normal temperature slots are closed, and the high temperature slot is connected to the test box, and the pre-stored heat is instantly introduced into the test box. Thus, the purpose of rapid temperature alternation is achieved.
