Title (EN) LOW THERMAL RESISTANCE POWER MODULE ASSEMBLY
(FR) ENSEMBLE DE MODULE DE PUISSANCE DE RESISTANCE THERMIQUE FAIBLE
Abstract:
(EN) A power module assembly (400) with low thermal resistance and enhanced heat dissipation to a cooling medium. The assembly includes a heat sink or spreader plate (410) with passageways or openings (414) for coolant that extend through the plate from a lower surface (411) to an upper surface (412). A circuit substrate (420) is provided and positioned on the spreader plate (410) to cover the coolant passageways. The circuit substrate (420) includes a bonding layer (422) configured to extend about the periphery of each of the coolant passageways and is made up of a substantially nonporous material. The bonding layer (422) may be solder material which bonds to the upper surface (412) of the plate to provide a continuous seal around the upper edge of each opening (414) in the plate. The assembly includes power modules (430) mounted on the circuit substrate (420) on a surface opposite the bonding layer (422). The power modules (430) are positioned over or proximal to the coolant passageways.
(FR) L'invention concerne un ensemble de module de puissance (400) à résistance thermique faible et dissipation de chaleur améliorée vers un agent de refroidissement. L'invention comprend un dissipateur thermique ou une plaque de répartition (410) avec des passages ou des ouvertures (414) pour le caloporteur qui s'étendent à travers la plaque à partir d'une surface inférieure (411) vers une surface supérieure (412). Un substrat de circuit (420) est fourni et placé sur la plaque de répartition (410) afin de recouvrir les passages du caloporteur. Le substrat de circuit (420) comprend une couche de liaison (422) conçue de manière à s'étendre sur la périphérie de chacun des passages de caloporteur et fabriquée à partir d'une matière sensiblement non poreuse. La couche de liaison (422) peut consister en une matière soudée qui lie la surface supérieure (412) de la plaque afin de fournir un joint continu autour du bord supérieur de chaque ouverture (414) dans la plaque. L'ensemble comprend des modules de puissance (430) montés sur le substrat de circuit (420) sur une surface opposée de la couche de liaison (422). Les modules de puissance (430) sont positionnés sur ou à proximité des passages de caloporteur.
