摘要:
The invention relates to a power semiconductor module comprising a plurality of power semiconductors that are fixed to a first side of a printed circuit board (26), and a cooling device that acts by means of a coolant, on a second side of the printed circuit board (26), opposite the first side, the cooling device comprising a plurality of cells through which the coolant is guided. The aim of the invention is to minimise the risk of failure of one such power semiconductor module. To this end, a non-cooled region (d, e, f) is arranged between at least two cells.

A cooling device comprising a heat-conducting cooling plate on the side of the electronic power components to be cooled and a platelike cooling fluid distributing device. The distributing device has cooling fluid outlets on the side facing the cooling plate, said outlets being arranged at a distance from and pointing towards the cooling plate. The distributing device also comprises at least one drain outlet for the cooling fluid. The cooling device comprises a first plate in which outlets and a plurality of drain outlets are evenly distributed and a second plate and a third plate which are superimposed, wherein two plates define a feed channel that is connected to all outlets and a drain channel that is connected to all drain outlets.

The invention provides a fluid cooling system comprising a heat exchanger with an outer wall forming a chamber with an inlet and an outlet for circulating a heat exchange medium in the chamber. The chamber has an opening towards the component which is to be cooled, and to protect the component, the opening is closed by a flexible wall which is attached to the outer wall. To protect the cover and the component against overload, the flexible wall is attached to an inner wall inside the chamber. The cooling system could be applied to electronic systems, e.g. for cooling a DCB substrate or similar electronic components.

A liquid-cooled power semiconductor unit has components to be cooled arranged on the upper side of a plate. The bottom side of the plate is cooled by liquid, which is guided along the plate by means of a distributing element, and the liquid inlet and the liquid outlet of the distributing element are preferably arranged perpendicular to the plate. The distributing element is divided into cells, where each cell has a liquid inlet and a liquid outlet perpendicular to the cooled plate, and the distributing element has multiple cells along the plate.
