Box Structure

The main body of the temperature, humidity, and vibration three comprehensive testing machine: the main body shell is made of high-quality A3 steel plate and has been spray treated, and the inner liner is made of SUS high-grade stainless steel mirror panel insulation medium, which is ultra-fine glass wool;
Loop mode: ToppartCentrifugal fan blades for air supply, bottom return air;
Double layer high tensile sealing strips with high temperature resistance are used between the door and the box to ensure the sealing of the testing area;
Using non reactive door handles makes operation easier;
The bottom of the machine is made of high-quality materialsfirmFixed PU activity wheel;
The observation window is made of multi-layer insulated tempered glass, with a laminated conductive film on the inner side (allowing for clear observation of the test process);
The lead hole (on the left side of the machine) can be used for external testing of power or signal lines (diameter 50mm);
Under the studiosquareEquipped with guide rails for moving the vibration table body in and out (when not conducting vibration tests);
The connection seal between the vibration table and the lower part of the studio adopts multiple layersringInterphase plug-in connection between oxygen resin and high-temperature resistant silicone rubber (for sealing);
Heating system selectionuseFin type stainless steel heater, with a heating core made of far-infrared nickel complex gold wire;
Two systems are independently controlled and do not interfere with each other;
Supply air circulation system Xiangming motor (low noise), multi wing centrifugal wind turbine, single cycle.

refrigeration system

The temperature, humidity, and vibration three comprehensive test mechanism refrigeration machine adopts the original French "Taikang" fully enclosed compressor;
The refrigeration system adopts unit or binary low temperaturewarmCircuit system design;
American "Ai Gao" drycrossFilter, Taiwan's "Guanya" oil separator, Italy's "Castello" solenoid valve;
Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, and ensuring even temperature and humidity distribution in the testing area;
The design of air circulation for air outlet and return, with wind pressure and speed meeting the testing standards, andapproveQuickly stabilize the temperature and humidity at the moment of opening the door;
Heating, cooling, and humidificationsystemComplete independence can improve efficiency, reduce testing costs, extend lifespan, and decrease failure rates.
