Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature control cabinets, in particular to a constant temperature control cabinet used in a dust-free workshop. Background Art

[0002] The gas control cabinet is a switchgear, measuring instrument, protective electrical appliance and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or alarmed with the help of protective electrical appliances. Various parameters in operation can be displayed by measuring instruments, and certain electrical parameters can be adjusted. It can also prompt or send signals when deviating from the normal working state.

[0003] Authorization announcement number CN216532383U discloses a constant temperature control cabinet for a dust-free workshop. This patented technology, when the peak temperature can no longer meet the heat dissipation demand through the heat dissipation window, the temperature sensor senses that the temperature inside the control cabinet is too high, and the processor starts the hydraulic pump to drive the hydraulic telescopic rod to extend, thereby opening the top lifting baffle. At this time, the lifting baffle will drive the sliding rod to move upward inside the sliding sleeve, thereby driving the triangular plate through the through groove into the fixed sleeve to squeeze one end of the I-shaped sliding sleeve, so that the I-shaped sliding sleeve shrinks toward the inside of the fixed sleeve. At this time, the baffle is separated from the I-shaped sliding sleeve, opening the I-shaped The notch of the sliding sleeve, at this time, the external air enters the control cabinet through the I-shaped sliding sleeve and the fixed sleeve, and then dissipates the heat through the cooling fan at the upper end, forming a cycle, which greatly increases the circulating air intake and can keep the internal temperature of the control cabinet stable; however, in this scheme, the hydraulic pump is started to drive the hydraulic telescopic rod to extend, and the top lifting baffle is opened to remove the heat source from the cooling fan. When in use, heating is first performed and then cooling is performed. This method is cumbersome to operate and has a poor temperature control effect. The setting of the heat dissipation device should be mainly in the strong electric part, and there is a disadvantage of electromagnetic interference. Therefore, a constant temperature control cabinet for a dust-free workshop is needed to improve the above problems. Utility Model Content
