Rapid change of temperature test box for aerospace products, electronic instruments, materials, electrical and electronic products, all kinds of electronic components to test the various performance indexes in the high and low temperature, or in hot and humid environment.
1, the rapid change of temperature test box body with CNC machine tool processing, beautiful appearance, and the use of no handle, easy to operate.
2, the bladder imported advanced stainless steel (SUS304) panels by the bravery of A3 cold rolled steel plate coating, increase the appearance and cleanliness.
3, the water tank is placed in the lower right part of the control box, and there is water automatic protection, more convenient operator to add water.
4, large observation window attached to the lamp to keep bright inside the box, and the use of heating body embedded toughened glass, at any time clear observation box condition.
5, the humidification system pipeline and control circuit board separately, can avoid because of humidification pipeline leakage fault, improve safety.
6, the water system piping circuit system is open, easy to maintain and repair.
7, the door and the box between the use of three layers of high temperature resistant sealing strip to ensure that the test area is closed.
8, on the left side of the box with a diameter of 50mm of the test cable hole, can be used to test the external power cord or signal line. (note the pore size or pore number shall be increased when ordering). The bottom of the machine adopts high quality fixed PU movable wheel.
Rapid change of temperature test box and compressor refrigeration system: in order to ensure the test box cooling rate and minimum temperature requirements, two cascade refrigeration system of the test box adopts a set of Taikang compressor component. Cascade refrigeration system comprises a high temperature refrigeration cycle and a low temperature refrigeration cycle, the connecting container for evaporative condenser, evaporator condenser is also to the role of the energy transfer, the studio heat energy to transmit through the two stage refrigeration system, to achieve the purpose of temperature. Refrigeration system design and application of energy regulation technology, an effective approach which can guarantee the normal operation of the refrigeration unit in the case and the energy consumption of the refrigeration system and refrigeration capacity effectively regulated, the refrigeration system operation cost and the failure rate dropped to more economic status.
Refrigerant: DUPONT company R404 (high temperature cycle), R23 (low temperature cycle)
Auxiliary parts: expansion valve (Danfoss), solenoid valve (Italy CASTEL);
Filter (Danfoss); oil separator (Taiwan crown pressure) and other refrigeration accessories are imported parts.
The high temperature and low temperature test box adopts the reverse cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant compressed to high pressure compressor power consumption by adiabatic, exhaust temperature, refrigerant through the condenser after isothermal and the surrounding medium for heat exchange, the heat to the surrounding medium. After the refrigerant through the valve adiabatic expansion work, then the refrigerant temperature decreases. Finally, the refrigerant absorbs the heat from the higher temperature object through the evaporator, which reduces the temperature of the object. This cycle continues to achieve the purpose of cooling
