Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, and specifically relates to a control cabinet for a hydraulic solenoid valve that can automatically cool down. Background Technique

[0002] A control cabinet is assembled with switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. When operating normally, the circuit can be connected or disconnected by means of manual or automatic switches.

[0003] In a disclosed automatic control cabinet and method with efficient heat dissipation in the Chinese utility model patent application publication specification CN115241775A, electrical components are installed on the surface of a connecting plate through sleeves by connecting pieces, and then a water pump is started. The water pump uses a return pipe to extract the coolant inside the connecting plate and inject it into a chiller. The chiller cools the coolant and injects it back into the connecting plate through a connecting pipe to form a cycle. The electrical components in contact with the connecting plate can complete heat exchange when contacting the coolant, thereby achieving the effect of improving the heat dissipation efficiency of the electrical components and solving the problem that the heat dissipation method of the existing control cabinet is relatively single, generally by exchanging the internal and external airflows of the control cabinet through a cooling fan and dissipating heat from the components. When the external environmental temperature is relatively high, its heat dissipation effect is greatly affected. However, when the cooling fan used for auxiliary heat dissipation is in use, due to the lack of a dust-proof component at the ventilation structure, dust is adsorbed on the surface of the components during the exchange of internal and external airflows, which will cause the lifespan of the components to be shortened over time and urgently needs to be developed.
