<p><P>PROBLEM TO BE SOLVED: To provide an electrical connection box having improved heat radiation performance. <P>SOLUTION: A wall surface of a case body 50 opposite to a circuit board 11 is recessed to the circuit board 11 side to form upper, lower and power supply connector fitting portions 36A, 36B and 36C, and thus, first, second and lower air flowing paths 47, 48 and 49 capable of vertically circulating air by utilizing the unevenness formed in a case 10. As the result, the air flowing into through an opening 23 of a fuse block 20 contacts a fuse 15 disposed inside the lower air flowing path 49, and moves upward by an chimney effect through the first and second air flowing paths 47, 48 from the lower air flowing path 49. The air is flown out from body side and cover side exhaust ports 45, 46, thereby exhausting heat generated from the fuse 15 to the outside of the case 10. As this result, the heat radiation performance of the electrical connection box can be improved. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
