Aluminum assembly board for heat generating elements utilized in inverter for photovoltaic application, has lateral and open flow channels formed with slats or bars, which comprise guiding groove that is formed in anchored base

摘要

The board has lateral flow channels (5a) and open flow channels (5b), which are arranged at a rear portion of the board for guiding cooling air. The flow channels are formed with slats or bars (11), which are arranged at distance from each other. The slats or bars comprise a guiding groove (7), which is formed in an anchored base (12) of the board. The bars are connected to transverse webs (14) at an external end. The transverse webs are associated with each other in pairs and arranged above the base.
