HEATING DEVICE FOR A VEHICLE, AND METHOD OF COOLING AN ELECTRONIC CONTROL UNIT OF THE HEATING DEVICE
First Claim
1. A heating device for a vehicle, comprising:
- a flow path for a liquid heat transport medium;
an electric heating unit generating heat; and
a heat transfer unit discharging generated heat from the electric heating unit to the heat transport medium in a heating section of the flow path, wherein the heat transfer unit and the heat discharge body are single piece; and
a first electronic control unit controlling the heating unit, the control unit including a heat discharge body discharging waste heat from the control unit to the heat transport medium in a preheating section of the flow path upstream of the heating section.

Abstract
The invention relates to a heating device (10) for a vehicle, comprising: a flow path (14, 16, 20, 22, 24) for a liquid heat transfer agent; an electric heating device (34) for generating heat and for releasing generated heat to the heat transfer agent on a heating portion (20) of the flow path; and an electronic controller (26) for controlling a heat output of the heating device. The controller (26) is provided with a heat releasing body in order to release waste heat of the controller (26) to the heat transfer agent on a preheating portion (16) of the flow path upstream of the heating portion (20). The invention likewise relates to a method for cooling the controller.

15. A method of cooling an electronic control unit of a heating device-in a vehicle, wherein the heating device includes a flow path for a liquid heat transport medium, an electric heating unit discharging heating heat to the beat transport medium in a heating section of the flow path, and the electronic control unit controlling the heating unit, said method comprising:
discharging waste beat from the control unit to the heat transport medium, wherein the control unit is provided with a heat discharge body arranged on a preheating section of the flow path upstream of the heating section, and the heat transport medium flows past or around the heat discharge body to receive the waste heat discharged from the control unit.
