- Such heat exchangers as Power Module Coolers are in the preferential embodiment designed as Pin Fin Coolers for high power applications in Motor and Motion Control, Hybrid Electric Vehicles and other Power Module systems.
- Heat sinks are so-called extended surfaces that have been used to enhance cooling of heat dissipating surfaces. Such heat sinks have been fabricated in a number of designs. The designs are such as to decrease fluid flow impedance through the heat sink and thereby improve heat dissipation performance.
- the pin fin heat sink is of particular interest because it is one of the commonly used heat sinks.
- This invention relates to a cooling system having one or more inclined pin fins for an electric motor controller.
- An object of the present invention is to provide a high performance heat sink for liquid cooled applications with controlled force for de-routing the stream of coolant fluid flow by means of the inclined pin fin array, wherein the coolant fluid flow is selectively focused and guided to the first surface by pushing force of inclined pin fins.
- the invention is based on the insight that cooling fluid flow is selectively guided to the local heat sources by pushing force, rather than by the drag force.
- Advanced heat exchanger with integrated array of inclined pin fins includes a base, i.e. first surface having the plurality of pin fins, wherein at least one pin fin comprises a central passage, where coolant fluid flow is selectively focused, thus the speed of the fluid is rapidly increased.

- illustrated streamlines of redirected coolant fluid flow (R) are pressed toward to the first surface (1-FS) due to the intensive pushing force produced by inclined pin fins (2) with central apertures (2-CA).
- the coolant fluid channel within the main cavity of the heat sink is designed as channel with its flat first surface (1-FS), and sideway channel barrier (1-CB), wherein the plurality of inclined pin fins (2) in array arrangement are protruding from the first surface (1-FS). Said inclined pin fins (2) are protruding up to the top of the coolant fluid channel, where the height of the pin fins (2-H) is approximately the same as the height of the coolant fluid channel.
- the array of inclined pin fins (2) actually acts as an internal quasi perforated wall of the heat sinks main cavity, where individual inclined pin fin (2) with central aperture (2-CA) generates a positive force which forces the coolant fluid flow toward to the first surface (1-FS).
- the figures in this application do not show the power electronics elements, i.e. enclosure, heat sources, etc. Instead, the figures of this application shows only the heat sink in preferential embodiment as a segment of the power electronics cooling system or housing, where other elements, such as cover of the coolant channel are present, but not shown on figures of this patent application.
- each individual pin fin (2) comprises a central aperture (2-CA), where the main coolant fluid flow passes the pin fin (2) array quasi barrier, thus the force for de-routing the stream of the coolant fluid flow is generated by means of inclined pin fin (2) with central aperture (2-CA) within the array arrangement.
- the pin fin (2) in exposed embodiment is designed as crescent moon type pin base, which is inclined at inclination axis (2-A) in relation to the first surface axis (1-FSA). Furthermore, the pin fin (2) in exposed embodiment comprises a second, pin fin (2) extraction area which consequently generates a pin fin (2) central aperture (2-CA) in accordance to the central aperture axis angle (A-2CAA). It can be understood, that the shape, area and height of the pin fin (2) central aperture (2-CA) is defined with shape, position and angle of extraction tool, which corresponds and thus exactly defines the shape of the pin fin (2).
- an inclined pin fin (2) with central aperture (2-CA) further comprise a coolant fluid flow collector (2-FC), where the fluid flow is collected and directed toward central aperture (2-CA) of the pin fin (2) arrangement.
- the pin fin (2) array is composed of pin fins (2), where a side passage (2-SP) between two neighbored pin fins (2) generates additional drag force due to the fluid flow principle, well known as Coanda effect.
- a pin fin (2) array arrangement comprise a pin fin top angle (TA), which is defined by three neighbored pin fins (2) due to the pin fin array pitch (2-P) and pin fin array raster (2-R), as shown and defined on Figure 4.
- TA pin fin top angle

Consequently the passing by coolant fluid flow is forced to follow and hit the pin fin (2) array configuration which contributes to enhanced efficiency of the heat sink.
- the boundary pin fin (2) is actually designed as row of pin fins (2) integrated into the channel boundary wall (1-CB), thus the pattern of the boundary fin (2) is defined and dictated by the main, i.e. primary pattern of the pin fin (2) array, as shown and defined on Figure 4.

Abstract
L'invention porte sur un échangeur thermique haute performance amélioré avec un moyen d'agencement d'ailettes en forme de broches inclinées (2), qui est caractérisé par le fait que chaque ailette en forme de broche individuelle (2) comprend une ouverture centrale (2-CA), et présentant au moins deux jonctions adhérentes avec une première surface (1-FS), chaque ailette en forme de broche individuelle (2) comprenant en outre un collecteur de flux de fluide de refroidissement (2-FC), qui guide et contraint le flux principal de fluide de refroidissement à s'écouler en direction de la première surface (1-FS) de la plaque de base du dissipateur thermique (1). L'invention repose sur l'idée de guider sélectivement l'écoulement d'un flux de fluide de refroidissement vers les sources de chaleur locales au moyen d'ailettes en forme de broche inclinées (2) selon le principe d'une déviation et d'une réorientation de l'écoulement du flux de fluide de refroidissement, plutôt que selon le principe physique d'une force de traînée.
