POWER SUPPLY APPARATUS
First Claim
1. A power supply apparatus for converting alternating current to direct current, comprising:
- a printed circuit board including a first region where an alternating current circuit component is mounted and a second region where a direct current circuit component is mounted, and having a longitudinal direction;
a first heat dissipation plate provided to stand in said first region on said printed circuit board; and
a second heat dissipation plate provided to stand in said second region on said printed circuit board,said first heat dissipation plate and said second heat dissipation plate each having a linear first straight portion and two second straight portions extending respectively from two ends of said first straight portion in respective directions opposite to each other as seen in a plan view, andat least a part of said first straight portion of said first heat dissipation plate and at least a part of said first straight portion of said second heat dissipation plate being opposite to each other, at least a part of one of said second straight portions of said first heat dissipation plate and at least a part of one of said second straight portions of said second heat dissipation plate being opposite to each other, and said second straight portions each being placed in said longitudinal direction of said printed circuit board.

Abstract
A power supply apparatus includes a printed circuit board having the longitudinal direction and including first and second regions where AC and DC circuit components are mounted respectively. A first heat dissipation plate and a second heat dissipation plate provided to stand respectively in the first and second regions each include, as seen in a plan view, a linear first straight portion and two second straight portions extending respectively from the two ends of the first straight portion in opposite directions respectively and in the longitudinal direction. Respective first straight portions of the first and second heat dissipation plates are opposite to each other, and one of the second straight portions of the first heat dissipation plate and one of the second straight portions of the second heat dissipation plate are partially opposite to each other.
