An electronic device including a sealed enclosure, the electronic components arranged inside the sealed enclosure and including high-loss high-temperature components, a main heat sink including ribs, wherein the high-loss high-temperature components are attached to the main heat sink and the ribs of the main heat sink are arranged outside the enclosure, a cavity formed inside the enclosure and divided into a plurality of channel-like sections, the channel-like sections configured for providing air flow guidance inside the enclosure and being interconnected at their ends, wherein at least one channel-like section contains the electronic components and at least one other channel-like section contains an air-to-air heat exchanger extending from inside the sealed enclosure to outside of the sealed enclosure, wherein the electronic components inside the at least one channel like section are adapted to be cooled by air flow inside the sealed enclosure.

Electronic device with waterproof enclosure

The subject of the invention is an electric power switchgear, an insulating radiator, and a method for installing the radiator in an electric power switchgear, and in particular in a medium or high voltage switchgear. The electric power switchgear comprising working elements placed in the housing and connected with busbars and branches, and cooled with air, is characterized in that it contains at least one insulating radiator made of thermoplastic material of increased thermal conductivity &#x3bb;&#x2267;2 W/mK, which is placed in the electric field of the switchgear and which is connected by a non-permanent fastening to at least one busbar or/and at least one branch. The insulating radiator designed for the switchgear is an injection molding including a base plate to whose top face a system of heat evacuating elements of identical or diverse shape is attached, and to its side surfaces elastic assembly catches are fixed.
