How to achieve the best of both heat dissipation and waterproofing for chassis cabinets

We all know that chassis cabinets generate a certain amount of heat during operation. If the heat is not dissipated in time, it may cause the entire chassis cabinet equipment to malfunction. How can we achieve the best of both worlds when the chassis cabinet needs to have waterproof function while dissipating heat?
Many people think that to achieve waterproofing, good sealing is necessary. As long as it is fully sealed, there will be no problem. However, let's think about it. After sealing, can the chassis and cabinets still dissipate heat? The answer is definitely not possible, so sealing well may not necessarily be the best choice for waterproofing.

The waterproofing of outdoor chassis cabinets is basically the same as the building waterproofing structure we know, but the windows of the switches have louvers that slope downwards from the inside out! This design not only effectively solves the heat dissipation problem of equipment inside the chassis and cabinet, but also provides a good rainproof effect for such equipment! There will also be some small holes at the bottom, in case water enters the chassis and cabinet, it can be drained in time without causing damage to the equipment inside the chassis and cabinet due to moisture!
