Abstract: A generator control unit (GCU) having thermal control includes a GCU housing having a first side and a second side. A printed wiring board (PWB) is within the GCU housing between the first side and the second side. The PWB includes a component side that faces a first side of the GCU housing. At least one through via is positioned through a thickness of the PWB. At least one boss is positioned on the component side of the PWB. The at least one boss extends from a component of the PWB to the first side of the GCU housing.

Abstract: An electronic control unit (20) comprising a cooling module (36) having at least one fluid channel (32) therein, a substrate (50) configured to define an interior region (52) and having an electronic component (54) mounted thereto, such that the electronic component (54) faces the interior region (52), and a cooling fluid (34) within the fluid channel (32), the cooling fluid (34) having a temperature below an operating temperature of the electronic component (54), wherein the cooling module (36) is positioned within the interior region (52), such that the heat generated by the electronic component (54) is convectively transferred to the cooling module (36). By integrating the cooling module (36) with the substrate (50) and by positioning the cooling module (36) in the interior region (52), the cooling module (36) is able to convectively cool the substrate (50).
