Abstract
An electronic control unit installed on a high temperature heat source or in its vicinity exhibits an improved heat dissipation ability within its installation environment. The electronic control unit has a chassis incorporating a printed circuit board where electronic devices are mounted. The outer surface of the chassis on the side of the high temperature heat source has a coating for lowering infrared absorption, while the outer surface of the chassis on the side away from the high temperature heat source has a coating for enhancing heat emissivity. Preferably, the inner surfaces of the chassis are subject to a surface treatment for increasing infrared absorption.
Claims17
An electronic control unit installed proximate to a high temperature heat source, the electronic control unit comprising:
- a chassis incorporating a circuit board where electronic devices are mounted, wherein
- an outer surface of said chassis on a side facing said high temperature heat source is subject to a surface treatment for decreasing an infrared absorption coefficient, and the outer surface of said chassis on a side facing away from said high temperature heat source is subject to a surface treatment for increasing a heat emissivity.
