Description

Technical Field

[0001] The utility model relates to the technical field of temperature change test boxes, in particular to a rapid temperature change test box. Background Art

[0002] Rapid temperature change test chamber is suitable for aerospace products, information electronic instruments, materials, electrical, electronic products, various electronic components to test the performance indicators of products under the condition of rapid temperature change. The high and low refrigeration cycles of the rapid temperature change test chamber adopt the reverse Carroll cycle, which consists of two isothermal processes and two adiabatic processes. The refrigerant is adiabatically compressed to a higher pressure by the compressor, consuming work to increase the exhaust temperature. After that, the refrigerant isothermally exchanges heat with the surrounding medium through the condenser, and transfers heat to the surrounding medium. The refrigerant then expands adiabatically through the valve to do work, and the refrigerant temperature decreases. Finally, the refrigerant absorbs heat from the object with a higher temperature isothermally through the evaporator, so that the temperature of the cooled object decreases. This cycle repeats itself to achieve the purpose of cooling.

[0003] The existing temperature change test chamber is large in size, has many precision instruments inside, and is heavy. During the loading and unloading process, it is mainly assisted by other large mobile equipment such as cranes or forklifts to move it to the ground, and then the pulleys at the bottom of the temperature change test chamber are used to move it in a plane. During the movement process, it is mainly moved by human push or pull. Due to the heavy weight of the temperature change test chamber, it is easy to roll over and collapse during the process by relying on the bottom pulley and manual push or pull. In addition, equipment such as plug-ins cannot enter the interior of the building, and the plane movement stability of the temperature change test chamber is difficult to guarantee. It is necessary to design a rapid temperature change test chamber to solve the above-mentioned problems. Utility Model Content
