Abstract: The invention relates to a cooling device for a printed circuit board, comprising a printed circuit board equipped with at least one face or first face and at least one heat sink (9) brazed to said at least one face of the printed circuit, in which said at least one heat sink (9) can be disposed in a flow of coolant. The invention is suitable for motor vehicles.

Abstract: The invention relates to a ventilation device (1) for a ventilation unit of a motor vehicle passenger compartment, comprising: an impeller (4) that generates an air flow (11, 12) and can be driven by an electric motor; and a printed circuit board (15) having secured thereto at least one electronic component (19) that can release calories. The printed circuit board (15) comprises at least one through-hole (18) provided in a part (21) of the printed circuit board (15). The ventilation device (1) is configured such that the air flow (11, 12) generated by the impeller (4) moves along said part (21) of the printed circuit board (15).

Abstract: The present invention concerns a thermal management and connection device for a battery module (1) consisting of cells (3) juxtaposed in parallel and connected to each other in series, each cell (3) comprising a positive terminal (4) and a negative terminal (4), said battery module (1) further comprising a heat exchange plate (10) comprising an inlet (12A) and an outlet (12B) for a heat-transfer fluid, positioned between the terminals (4), and a non-conductive connection plate (20) comprising holes (22) for the passage of the terminals (4) and means (6) for connecting said terminals (4) two by two with each other, the connection plate (20) being a printed circuit comprising conductor tracks (60).

Abstract: The present invention relates to a power supply module (100) for an electrical device (10), in particular using direct current, the power supply module (100) including a capacitor-input filter (120) arranged in parallel on the electrical device (10). The power supply module (100) comprises a means (130, 200) for detecting the discharge current (Icc) supplied by the capacitor-input filter (120) following a short-circuit in the power supply module (100). The invention can be used the power supply circuits of automobile electrical devices, in particular the motors of an electric fan unit for creating an air flow in heating, ventilation and/or air-conditioning systems.
