FIXING STRUCTURE AND FIXING METHOD OF CIRCUIT BOARD WITH EMBEDDED ELECTRONIC PARTS TO COOLER
First Claim
1. A fixing structure comprising:
- a cooler including a plurality of fixing parts arranged in a first direction, each of the fixing parts defining a refrigerant passage therein through which refrigerant flows; and
a circuit board fixed to the cooler, the circuit board including a wiring part, a plurality of electronic parts electrically connected to the wiring part, and an insulating base material containing resin and embedding the wiring part and the electronic parts therein, the insulating base material including embedding portions in which the electronic parts are embedded and a bent portion having flexibility between the embedding portions, whereinthe bent portion is opposed to an end portion of one of the fixing parts, the end portion being located at an end of the one with respect to a second direction perpendicular to the first direction, andeach of the embedding portions is held by adjacent two fixing parts such that opposite surfaces of the embedding portion are closely in contact with the adjacent two fixing parts.

Abstract
In a fixing structure of a circuit board to a cooler, the circuit board includes a wiring part, electronic parts electrically connected to the wiring part and an insulating base material embedding the wiring part and the electronic parts therein. The insulating base material includes embedding portions in which the electronic parts are embedded and a bent portion having flexibility between the embedding portions. The cooler has fixing parts arranged in a first direction. The circuit board is fixed to the cooler while bending the bent portion. The bent portion is opposed to an end portion of one of the fixing parts, and each of the embedding portions is held between adjacent two fixing parts such that opposite surfaces of the embedding portion are closely in contact with surfaces of the adjacent two fixing parts.

17. A fixing method for fixing a circuit board to a cooler, the circuit board including a wiring part, a plurality of electronic parts electrically connected to the wiring part and an insulating base material embedding the wiring part and the electronic parts therein, the insulating base material including embedding portions embedding the electronic parts therein and a flexible portion between the embedding portions, the cooler including a plurality of fixing parts arranged in a first direction and defining a refrigerant passage therein through which refrigerant flows,
the fixing method comprising: -
arranging the circuit board to the cooler while bending the flexible portion such that each of the embedding portions is disposed between adjacent two fixing parts and the flexible portion is opposed to an end portion of one of the fixing parts, the end portion being at an end of the one with respect to a second direction perpendicular to the first direction; and applying pressure to the cooler in a direction parallel to the first direction such that opposite surfaces of each of the embedding portions are brought into contact with the adjacent two fixing parts and the embedding portion is held by the adjacent two fixing parts - View Dependent Claims (18)
