Title
(DE) KÜHLKÖRPER MIT EINER INTEGRIERTEN STROMSCHIENE
(EN) HEAT SINK WITH INTEGRATED BUS BAR
(FR) PUITS DE CHALEUR A BARRE OMNIBUS INTEGREE
Abstract
(EN)
The invention centers around a circuit board assembly (12) having a heat sink (30) with a buss bar (20) integrally formed therein. Preferably, the heat sink (30) is provided between two parallel, opposed circuit boards (14, 16). The buss bar (20) is provided between the two circuit boards and is in electrical contact with circuit modules (18) provided on both of the circuit boards (14, 16). The heat sink (30) effectively conveys heat away from the circuit board assembly (12) generated by current flowing through the several circuit modules (18) provided on the circuit boards (14, 16). Preferably, the buss bar (20) is electrically insulated from both the circuit boards (14, 16) and the heat sink (30) but electrically connected to the circuit modules (18) provided on the surfaces of the circuit boards (14, 16) by terminals (56, 58) protruding from the opposed surfaces of the buss bar (20).

(FR)
Cette invention concerne un ensemble de plaquettes de circuits (12) ayant un puits de chaleur (30) à barre omnibus intégrée (20). De préférence, le puits de chaleur (30) est disposé entre deux plaquettes de circuits opposées et parallèles (14, 16). La barre omnibus (20) est disposée entre les deux plaquettes de circuits et est en contact électrique avec des modules (18) de circuits situés sur les deux plaquettes de circuits (14, 16). Le puits de chaleur (30) dissipe efficacement la chaleur émanant de l'ensemble de plaquettes de circuits (12), chaleur produite par le passage du courant à travers plusieurs modules (18) de circuits des plaquettes de circuits (14, 16). De préférence, la barre omnibus (20) est électriquement isolée, d'une part, des plaquettes de circuits (14, 16) et d'autre part, du puits de chaleur (30) mais elle est reliée électriquement aux modules (18) de circuits se trouvant à la surface des plaquettes de circuits (14, 16) par des bornes (56, 58) formant saillie sur les faces opposées de la barre omnibus (20).
