Description

Technical Field

[0001] The utility model relates to the technical field of LNG filling, and more specifically, to a control cabinet for an LNG filling station. Background Art

[0002] An LNG filling station is a facility used to provide fuel for vehicles powered by liquefied natural gas. An LNG filling station control cabinet is a device used to monitor and control the operation of the LNG filling station. These control cabinets typically include various sensors, instruments, and control devices used to monitor various parameters within the LNG filling station and automatically or manually control the filling station equipment.

[0003] After searching, the Chinese patent with application number CN202122173788.4 discloses an LNG filling station system control cabinet. The system control boxes in each LNG filling station are currently connected to ordinary distribution cabinets and do not have a good heat dissipation system. The internal electronic components are very easy to generate heat, affecting the use of the internal electronic components. When the temperature sensor detects that the temperature inside the cabinet is too high, the fan starts, and the air is extracted through the air inlet pipe group, and then discharged into the cooling pipe. The air passes through the cooling pipe and passes through the base. The water in the base cools the air, and then enters the cabinet to cool the cabinet, and then absorbs heat and discharges it out of the cabinet through the base. It is easy to use, effectively solves the high temperature problem, and effectively guarantees the use effect.

[0004] When the LNG filling station control cabinet needs to be inspected and maintained, the front door is usually opened for inspection. However, the control cabinet does not provide sufficient operating space after opening, making it difficult for maintenance personnel to conduct a comprehensive and detailed inspection of the interior, affecting the quality of maintenance. At the same time, the inspection is more troublesome, affecting the inspection and maintenance efficiency. Utility Model Content
