Abstract: This document describes a cooling device for cooling a heatsink having a plurality of cooling fins provided on a heatsink base. The cooling device includes a centrifugal fan having a fan inlet and a fan outlet, a support for mounting the fan above the heatsink, and a baffle locatable between the support and the heatsink base. The baffle defines an inlet pathway for feeding air between the cooling fins over the heatsink base to the fan inlet and an outlet pathway for expelling air from the fan outlet.

Abstract: An electronic system is described that comprises a first board and a first processing unit, wherein the first processing unit comprises a first semiconductor chip arranged on a first surface of the first board; a first cooling unit facing the first surface of the first board and configured to cool the first semiconductor chip; at least one further board and a second processing unit, wherein the second processing unit comprises a further semiconductor chip arranged on a first surface of the at least one further board; and a second cooling unit facing the first surface of the at least one further board and configured to cool the further semiconductor chip. The first board and the at least one further board are spaced apart from each other. The first cooling unit is a passive cooling unit, and the second cooling unit is an active cooling unit.

Abstract: The present disclosure relates to a cooling system for cooling an electronic component, the cooling system comprising a heat sink with a cooling channel for guiding a liquid. The heat sink comprises an external surface comprising at least one opening which partially exposes the cooling channel. The electronic component is mounted to the external surface such that the electronic component covers the opening. A sealing material is arranged between the electronic component and the external surface for at least partially sealing the electronic component against the liquid. The present disclosure further relates to a method for assembling a cooling system, the method comprising: forming at least one opening through an external surface of a heat sink; dispensing a sealing material in a liquid state over the external surface around the at least one opening for forming a molding; and pressing the electronic component onto the molding.

Abstract: An electronic device for a vehicle includes a metal tubular casing extending longitudinally and opening at its two ends, and a wall having a curved profile with cooling fins on its outer surface. The electronic device includes an assembly of printed circuit boards comprising a first plurality of printed circuit boards that include heat-generating electronic components. The printed circuit boards of the assembly are connected together by flexible conductive elements. The device further comprises a first heat sink arranged inside the tubular casing comprising a curved wall generally extending parallel to the curved wall of the tubular casing. The first plurality of printed circuit boards is interposed between the curved inner surface of the wall of the casing and the curved wall of the first heat sink so heat is dissipated through the first heat sink and through the curved wall equipped with cooling fins of the tubular casing.
