Embodiment Construction

[0038] In the following description, features and functions well known to those skilled in the art will not be described in detail.

[0039] figure 1 An electronic circuit board 2 is shown with a plurality of electronic power components mounted on a cooling plate 4 .

[0040] Here, the electronic power element refers to an element that can pass an alternating current or direct current of tens of amperes without being damaged. Typically it involves a switch capable of switching this current.

[0041] Here, the circuit board 2 has five power switches 6 to 10 . These power switches are implemented with IGBT transistors (Insulated Gate Bipolar Transistors). figure 1 The other electronic components shown are not necessary to understand the operation of the cold plate and therefore will not be described in detail here.

[0042] One side of the cooling plate 4 has a positioning plane 13 which removably receives four connections 14 to 17 for fluidly connecting the cooling plate 4 ...

Abstract

The board has a cold plate including a projection plate (42) between intake and evacuation holes (70, 72). Rectilinear nozzles (86-90) traverse the plate through and through by following a projection direction. Length of each nozzle along the direction is higher than / equal to width of the nozzle perpendicular to the direction for forming coolant e.g. water, jets (100-104) along the projection direction. The projection direction of each nozzle forms an angle (alpha) with respect to a direction perpendicular to a base plate (78), where the angle ranges between minus 30 to plus 30 degrees.

Description

technical field [0001] The invention relates to an electronic circuit board and a cooling plate for cooling the circuit board. Background technique [0002] There is an electronic circuit board which has: [0003] - at least one electronic power component with a base plate in direct contact with the heat-carrying fluid, [0004] - a cooling plate on which the base plate of the electronic power components is fastened in a heat-tight manner against the heat transfer fluid, the cooling plate having: [0005] at least one recess opening to the underside of the base plate of the electronic power component, [0006] an inlet hole for the heat transfer fluid to enter the recessed portion, and [0007] • A discharge hole through which the heat transfer fluid flows out of the recessed portion. [0008] For these electronic circuit boards, some plastic inserts are inserted into the recessed parts. Each insert has a plurality of channels that are fluidly connected to the access ho...
