Abstract
Disclosed is a heating plate for a flow heater having a substrate made of metal, a heating resistor arranged on one side of the substrate and fins arranged on an opposite side of the substrate. The fins are brazed to the substrate, made of corrugated sheet metal and provided with a series of cuts across ridges of the corrugated sheet metal. According to this disclosure, the ridges are compressed such that opposing surfaces on the inside of the ridges contact each other.
Claims13
A heating plate for a flow heater, comprising:
- a substrate made of metal;
- a heating resistor arranged on one side of the substrate and fins arranged on an opposite side of the substrate;
- wherein the fins are brazed to the substrate, made of corrugated sheet metal and provided with a series of cuts across ridges of the corrugated sheet metal;
- and
- wherein the ridges are compressed such that the fins are arranged at a distance that is larger than a thickness of the fins, said thickness measured at a position halfway between proximal and distal ends of the fins.
The heating plate according to claim 1, wherein the cuts have a width that is larger than half the thickness of the fins. 10 The heating plate according to claim 9, wherein the cuts have a width that is larger than the thickness of the fins and smaller than ten times the thickness of the fins.
