  • Methods for and apparatuses of a circuit board cooling device
    Patent number: 12069795
    Abstract: Disclosed are aspects of apparatuses and methods of fitting a cooling device to a circuit board for cooling a high-power electronic component mounted on the circuit board. Cooling apparatuses, and arrangement thereof, are also described. The method provides the cooling device with a cooling surface having a cooling area for thermally connecting to a to-be-cooled surface of the electronic component. Fixing elements are provided for moving the cooling surface towards the circuit board. A distance position “d” of the to-be-cooled surface from the circuit board is determined, and on this basis spacer elements are selected to be interposed between the cooling device and the circuit board to limit the movement by the fixing elements to a position where the cooling area is in proximity to the to-be-cooled surface.
