- the expression "at least” is to understand that the support plates with at least one provided upended end and also with the metallic Frame of the housing can be coupled thermally conductive. In this case, then takes place a heat conduction both over the Mounting plate as well as the carrier plate. As far as the Support plate should also be support plate at the same time, what is quite possible, takes place solely on them, the heat dissipation. It is advantageous - for structural reasons - the Bracket plate divided into two mounting plates, one of which one for example the power supply and the other the control computer wearing.
- a two-sided LED display is advantageous one Support plate with the holder holding the power supply and the other support plate with the control computer haltering Bracket plate connected thermally conductive. This is done two-sided, uniform heat dissipation over the heat transferring parts within the housing that conduct heat coupled to the frame of the housing.
- the upstand of the ends of the support and / or the Carrier plate at the ends should be for a large Heat transfer surface of theseêtkanteten ends of the Metal frame worry. This is especially true when between the amongkanteten ends and the inside of the metal frame one thermally conductive paste or a thermally conductive gel to increase the Thermal conductivity is provided and the réellekanteten ends for example, pressed by appropriate screws - and thus without air gap - pulled against the inner surfaces of the frame sides become.
