Abstract:
1. An ultrasound scanner, comprising: an ultrasound probe with a housing having a surface enclosing an internal cavity; a printed circuit board (PCB) in the internal cavity of the housing that includes a plurality of semiconductor devices carried by the printed circuit board (PCB); and a heat distributor between the surface of the housing and the printed circuit board, the heat distributor being in thermal communication with both the semiconductor devices and the surface of the housing, wherein the heat distributor includes a laminated structure having at least two conductive layers including at least a first conductive layer that is thermally coupled to at least one heat producing semiconductor device, a second conductive layer that is thermally coupled to the surface of the housing and an insulative layer disposed between the first and second conductive layers, wherein the insulative layer includes a region that is more heat conductive than a surrounding region of the insulative layer and that is laterally offset from the heat producing semiconductor device to allow heat to flow from the first conductive layer to the second conductive layer of the laminated structure.
