Abstract
An electric heating device includes at least two hollow profile elements which form a fluid channel for a fluid to be heated and, opposite the fluid channel, a heating chamber which is bounded by opposite contact surfaces against which at least one PTC element abuts in a heat-conducting manner. A scalable and easier to assemble electric heating device is achieved by connecting the hollow profile elements to one another by complementary form-fit segments.
Claims11
An electric heating device, comprising:
- at least two hollow profile elements which form a fluid channel for a fluid to be heated and which form a heating chamber which is bounded by opposite contact surfaces;
- at least one PTC element which abuts against at least one of the contact surfaces in a heat-conducting manner;
- and
- complementary form-fit segments which connect the hollow profile elements to one another such that the form-fit segments also provide a connection of the hollow profile elements in a first direction orthogonal to the contact surfaces.
