Abstract
A heat exchanger and a method for manufacturing a heat exchanger, the heat exchanger comprising: a first plurality of layers, each of the first plurality of layers including: a corrugated sheet comprising a series of regular corrugations across its width for flow of liquid therethrough, the series of corrugations having a predetermined period; and a de-congealing channel for flow of liquid across the width of the corrugated sheet in parallel with the corrugations, the de-congealing channel formed at least in part by two adjacent corrugations, that are separated by greater than the predetermined period.
Claims15
A heat exchanger comprising:
- a first plurality of layers, each of the first plurality of layers including:
- a corrugated sheet comprising a series of regular corrugations across its width for flow of liquid therethrough, the series of corrugations having a predetermined period;
- and
- a de-congealing channel for flow of liquid across the width of the corrugated sheet in parallel with the corrugations, the de-congealing channel formed at least in part by two adjacent corrugations that are separated by greater than the predetermined period.
A method of manufacturing a heat exchanger, comprising:
- forming a layer of the heat exchanger by stamping a series of regular corrugations with a predetermined period into a metal sheet, and skipping a corrugation stamping step so as to create a space between two adjacent corrugations which are thus separated by greater than the predetermined period, and thereby create at least a part of a de-congealing channel.
