Electronic control unit with integrated cooling module
First Claim
1. A electronic control unit comprising:
- a cooling module having a first plate and second plate, the first plate contacting the second plate to define at least one fluid channel therebetween;
a substrate configured to define an interior region and having an electronic component mounted to the substrate, such that the electronic component faces the interior region; and
a cooling fluid within the fluid channel, the cooling fluid having a temperature below an operating temperature of the electronic component, wherein the cooling module is positioned within the interior region, such that heat generated by the electronic component is convectively transferred to the cooling module.

Abstract
An electronic control unit (20) comprising a cooling module (36) having at least one fluid channel (32) therein, a substrate (50) configured to define an interior region (52) and having an electronic component (54) mounted thereto, such that the electronic component (54) faces the interior region (52), and a cooling fluid (34) within the fluid channel (32), the cooling fluid (34) having a temperature below an operating temperature of the electronic component (54), wherein the cooling module (36) is positioned within the interior region (52), such that the heat generated by the electronic component (54) is convectively transferred to the cooling module (36). By integrating the cooling module (36) with the substrate (50) and by positioning the cooling module (36) in the interior region (52), the cooling module (36) is able to convectively cool the substrate (50).
