Abstract

Official abstract text for this publication.

A heat radiating member and an electrical junction box are provided that have a simple configuration and are capable of quickly radiating heat generated by a semiconductor device. A support member, which receives heat from a substrate portion having a mounting face on which a semiconductor device is mounted, via an opposing plate portion opposing the mounting face, and radiates the received heat, includes a recessed portion formed in the opposing plate portion, at a position corresponding to the semiconductor device. The recessed portion has a wall thickness that is greater than that of another portion of the opposing plate portion.

First claim

Opening claim text (preview).

What is claimed is: 1. An electrical junction box comprising: a heat radiating member that receives heat from a substrate portion having a mounting face on which a semiconductor device is mounted, via an opposing plate portion opposing the mounting face, and radiates the received heat, the heat radiating member including: a recessed portion formed in the opposing plate portion, at a position corresponding to the semiconductor device, wherein the recessed portion has a wall thickness that is greater than that of another portion of the opposing plate portion; an accommodating portion configured to accommodate the substrate portion; and a heat conductive material interposed between the substrate portion and the opposing plate portion of the heat radiating member. 2. The electrical junction box as set forth in claim 1 , wherein a wall portion of the recessed portion excluding a bottom portion has a wall thickness that is greater than that of another portion of the opposing plate portion. 3. The electrical junction box as set forth in claim 1 , wherein an elongated wall portion of a wall portion of the recessed portion excluding a bottom portion, the elongated wall portion extending in a longitudinal direction of the recessed portion, has a wall thickness that is greater than that of another portion of the opposing plate portion. 4. The electrical junction box as set forth in claim 1 , further comprising: a radiation fin that is flush with an outer face of the elongated wall portion and is continuous with an end portion of the elongated wall portion.
