Patent ID: 6995978

Claim:
An actively externally cooled housing ( 1 ) with at least one electronic component ( 2 , 3 ) having heat-dissipating capacity, comprising a ventilation inlet ( 4 ) located outside the housing ( 1 ), the ventilation inlet generating an airflow ( 5 , 6 , 7 ) that is guided through a lateral flow channel ( 8 ), the flow channel being located on any side wall ( 9 ) of the cooled housing ( 1 ) on which at least one electronic component ( 2 , 3 ) with heat-dissipating capacity is located, wherein the ventilation inlet ( 4 ) is located in a ventilation housing ( 11 ) that is located on the top side ( 13 ) of the active-cooled housing ( 1 ) and has a lateral air outlet that leads into the lateral flow channel ( 8 ), whereby an air intake occurs through only one air inlet opening ( 10 ) that is located on the underside of the ventilation housing ( 11 ) and which is essentially open vertically downward ( 12 ), so that the ventilation unit ( 4 ) is located in the ventilation housing ( 11 ) in such a manner that it is protected against impurities in the ambient air.
