Abstract
A heating circuit and an electronics assembly for use in a vehicle includes 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 is located in the electronics cavity adjacent to the internal wall. A control electronics assembly is located in the electronics cavity adjacent to the heat generating electronics assembly, with the control electronics portion controlling the heat generating electronics assembly; and an internal heat shield extending between and shielding the control electronics assembly from the heat generating electronics assembly, with the internal heat shield being made of a thermally conductive material and having a contact portion attached to the internal wall, whereby heat absorbed by the internal heat shield transmitted to the internal wall.
