Description

Technical Field

[0001] The utility model belongs to the technical field of door panel waterproofing, in particular to a negative pressure-proof water guide groove of an air inlet door panel of a frequency conversion room. Background Art

[0002] Fracturing frequency conversion room usually adopts air cooling for system heat dissipation. In order to have sufficient heat dissipation power and protection, air inlet shutters are usually installed on the door panel side. Large transformers, inverters and other heating devices are installed inside the fracturing frequency conversion room. The air cooling system usually uses multiple high-power high-speed fans to dissipate the internal heat and discharge it from the upper air outlet of the room.

[0003] When the weather is bad and rain is pouring, the heat dissipation requirement requires a large air volume, which will cause a large negative pressure inside. This will cause rainwater to flow back into the filter from the slope of the air inlet louvers. After a long time, the filter cotton will be filled with water and drip from top to bottom, and then be brought into the room by the wind speed of the lower louvers. There is a hidden danger of water inflow and failure of high-power electrical appliances. To this end, we provide a negative pressure water guide groove for the air inlet door plate of the frequency conversion room to solve the above problems. Utility Model Content
