Abstract
A heat exchanger including a perforated heat transmission element, a heat transmission enhancing device for producing a pressure difference between opposite surfaces of at least a portion of the perforated heat transmission element, and a main fluid flow guiding structure for guiding the fluid along the perforated heat transmission elements without substantial flow of the fluid through the perforations.
Claims28
A heat exchanger apparatus comprising:
- a heat transmission member having a plurality of through-holes, said heat transmission member extending in a direction of fluid flow and being corrugated in the direction of fluid flow in the form of alternating trapezoids to produce a pressure difference between opposite surfaces of each of plural portions of said heat transmitting member;
- and main flow guide means for guiding a main portion of said fluid flow such that it does not pass through said through-holes but flows along said heat transmitting member.
A heat exchanging apparatus comprising:
- a first heat transmission member having a plurality of through-holes formed therein, said heat transmission member extending in the direction of fluid flow and being corrugated in the direction of fluid flow in the form of alternating trapezoids to produce a pressure difference between opposite sides of one portion of said first heat transmission member;
- a second heat transmission member coupled thermally to said first heat transmission member, a temperature of said first heat transmission member being different from that of said second heat transmission member;
- and main fluid guide means for guiding a main flow of said fluid along said first heat transmission member while preventing said main flow from passing through said through-holes of said first heat transmission member.
A heat exchanging apparatus comprising:
- a first heat transmission member having a uniform distribution of a plurality of through-holes in at least one portion thereof, said heat transmission member extending in said direction of fluid flow;
- a second heat transmission member coupled thermally to said first heat transmission member, a temperature of said first heat transmission member being different from that of said second heat transmission member;
- heat transmission enhancing means for producing a pressure difference between opposite sides of one portion of said first heat transmission member;
- and main fluid guide means for guiding a main flow of said fluid along said first heat transmission member while preventing said main flow from passing through said through-holes of said first heat transmission member;
- and
- wherein said heat transmission enhancing means is provided by corrugating said first heat transmission member periodically in the direction of said fluid flow to form alternating trapezoids.

A heat exchanger apparatus, comprising:
- a heat transmission member extending in a direction of fluid flow;
- heat transmission enhancing means for producing a pressure difference between opposite surfaces of each of plural portions of said heat transmitting member, each of said plural portions of said heat transmitting member having a uniform distribution of a plurality of through-holes therein;
- and main flow guide means for guiding a main portion of said fluid flow such that it does not pass through said through-holes but flows along said heat transmitting member.
A heat exchanger apparatus, comprising:
- a heat transmission member having first, intermediate and second sections arranged along a direction of fluid flow, said second section having at least one perforation therein;
- and
- means for defining a first fluid path on a first side of said heat transmission member and a second fluid path on a second side of said heat transmission member, with the cross-sectional areas said first and second fluid paths having a first ratio along said first section of said heat transmission member, changing along said intermediate section of said heat transmission member and then having a second ratio along said second section of said heat transmission member, the length of said second section being substantially longer than said intermediate section.
