<p>PROBLEM TO BE SOLVED: To provide an electronic component unit that can efficiently radiate heat generated by an electronic component by dispersing it without making a high temperature part, and that has made it possible to miniaturize itself by not being provided with a heat sink.SOLUTION: In an electronic component unit 10, chassis 12 inside which an electronic component 11 to control a traffic signal is mounted is made of good thermal conductive material, the shape of the chassis 12 doubles as a radiator plate by forming it like a rectangular box inside which openings 15 provided at both ends in the longitudinal direction are connected, the electronic component 11 is fixed to an electronic component mounting surface 13b of a plate-shaped bracket 13, and a fixing surface 13c opposite to the electronic component mounting surface 13b is fixed to the chassis 12 by making it contact on the surface.</p> |
