Abstract
A method for forming a heat exchanger plate includes: securing a wave form metallic sheet to a heat exchanger plate substrate, the substrate comprising a first face and a second face opposite the first face, the securing of the wave form metallic sheet being to the first face; and removing peaks of the sheet.
Claims22
A method for forming a heat exchanger plate, the method comprising:
- securing a wave form metallic sheet having a plurality of waves to a heat exchanger plate substrate, the substrate comprising a first face and a second face opposite the first face, the securing of the wave form metallic sheet being of troughs of the wave form to the first face;
- and
- after the securing, cutting off peaks of the wave form metallic sheet to create pairs of fins, each fin extending to a free distal end and the fins of each pair joined by an intact trough of the wave form metallic sheet.
A method for forming a heat exchanger plate from a substrate and a metallic corrugation, wherein:
- the substrate comprises:
- a first face and a second face opposite the first face;
- at least one first port and at least one second port;
- and
- at least one passageway along a flowpath between the at least one first port and the at least one second port;
- the metallic corrugation comprises:
- a plurality of peaks and a plurality of troughs;
- and
- the method comprises:
- securing the troughs of the metallic corrugation to the substrate first face;
- and
- after the securing, cutting the peaks off the metallic corrugation to leave pairs of fins,
- wherein for each pair the fins are connected by the associated trough and each fin extends to a respective free distal end.
