Electric heating device for heating fluids

An electric heating device for heating fluids, comprising:

• a housing having an upper housing part, a lower housing part and housing walls arranged on the upper and lower housing parts, the housing walls including two base walls wherein the upper housing part and the lower housing part each define one of the base walls;
• an inlet connection piece arranged at an inlet opening of the housing and an outlet connection piece arranged at an outlet opening of the housing;
• a flow path through which the fluid to be heated can flow and which is disposed inside the housing and leads from the inlet connection piece to the outlet connection piece;
• an electric heating unit attached to at least one of the housing walls outside of the flow path;
• wherein the flow path comprises an inlet chamber, an outlet chamber and at least two flow channels running side by side from the inlet chamber to the outlet chamber;
• wherein each of the at least two flow channels starts at the inlet chamber and ends at the outlet chamber;
• wherein at least one of the housing walls is a separating wall that separates two side-by-side channels of the at least two flow channels from one another wherein opposite sides of the separating wall defines a portion of each of the two side-by-side channels;
• wherein each of the at least two flow channels has an inlet section connected to the inlet chamber and defining an inlet flow direction and each of the at least two flow channels has an outlet section connected to the outlet chamber and defining an outlet flow direction and wherein each of the at least two flow channels are disposed between and partially defined by the base walls on the upper and lower housing parts;
• wherein the inlet connection piece is oriented in the inlet flow direction and/or the outlet connection piece is oriented in the outlet and wherein the housing walls arranged on the upper and lower housing parts define at least one gap between the housing walls permitting fluid leakage from one of the side-by-side fluid channels to the other side-by-side fluid channel.
