Abstract
The present invention relates to an electric fluid-heating device (1), in particular for a motor vehicle, comprising a housing having a first fluid-circulation chamber (21), at least one electric heating element (4) for heating the fluid in said first chamber (21), an electronic board (81) for controlling a current circulating in said electric heating element or elements (4), at least one thermal sensor. Said device is characterised in that the thermal sensor or sensors are positioned on the electronic board (81) and thermally connected to the first chamber (21) via a heat sink (9).
Claims7
An electric fluid heating device for a motor vehicle, the electric fluid heating device comprising:
- a housing comprising a first chamber configured to circulate a fluid and a separating wall;
- at least one electric heating element configured to heat the fluid in the first chamber;
- a controller comprising an electronic circuit board, wherein the controller is configured to control a current circulating in the at least one electric heating element;
- and
- at least one thermal sensor,
- wherein the at least one thermal sensor is positioned at the electronic circuit board arranged within the housing and thermally connected to the first chamber via a heat sink arranged within the housing,
- wherein the electronic circuit board is arranged in a second chamber of the housing, the second chamber being separated from the first chamber by the separating wall,
- wherein the heat sink comprises at least one column formed in the second chamber and extending from the separating wall, the at least one column being in contact with the electronic circuit board, and
- wherein the at least one column supports the electronic circuit board.
