Abstract:
1. A heating circuit and an electronics assembly for use in a vehicle comprising: an external housing having outer walls and an internal wall dividing the external housing into an electronics cavity and a non-electronics cavity; a heat generating electronics assembly located in the electronics cavity adjacent to the internal wall; a control electronics assembly located in the electronics cavity adjacent to the heat generating electronics assembly, the control electronics portion configured to control the heat generating electronics assembly; and an internal heat shield extending between and shielding the control electronics assembly from the heat generating electronics assembly, the internal heat shield being made of a thermally conductive material and having a contact portion attached to at least one of the internal wall and the outer walls, whereby heat absorbed by the internal heat shield from the heat generating electronics assembly is transmitted to at least one of the internal wall and the outer walls.
