A cabinet (100; 200) for housing electric/electronic components (110, 120) comprises:
- a first compartment (101; 201) housing components that require cooling in operation (110);
- a second compartment (102; 202) housing components that do not require cooling in operation (220); and
- a third compartment (103; 203) housing a heat exchanger (130) with an intake fan (131) extracting incoming air from the second compartment (102; 202) and a fan (133) injecting heat exchanger cooled air in the first compartment (101; 201). The second compartment (102; 202) of the cabinet (100; 200) further comprises:
- a pollution filter free air intake opening (241) configured to allow an incoming external air stream (150; 250) to enter the second compartment (102; 202); and
- a hit plate (151; 251, 252) positioned and oriented in the second compartment (102; 202) and configured to cause the incoming external air stream (150; 250) to slow down and deposit pollution particles on the hit plate (151; 251, 252). |
