Abstract
A heat exchanger (10) in accordance with the invention includes first and second heat conductive, spaced apart plates (12 and 14) and a heat conductive sheet (16) disposed between the plates and having repeating ridges (18) in thermal contact with the plates with successive ridges facing a different one of the plates and sections (22) of the sheet between successive ridges being inclined with respect to the axis of fluid flow and containing at least one aperture (32, 34 and 38) extending between the opposed surfaces of the section for passing fluid flow through the at least one aperture when fluid flows along the axis of fluid flow with fluid flow through the at least one aperture of the plurality of sections producing jets of fluid contacting one of the plates.
Claims27
A heat exchanger comprising:
- first and second heat conductive spaced apart plates;
- a heat conductive sheet disposed between the plates and having repeating ridges in thermal contact with the plates with successive ridges facing a different one of the plates;
- and
- sections of the sheet disposed between successive ridges being inclined with respect to the axis of fluid flow and containing at least one aperture with the at least one aperture between opposed surfaces of the section passing fluid flow through the at least one aperture when fluid flows along the axis of fluid flow and with fluid flow through the at least one aperture of a plurality of the sections producing jets of fluid contacting one of the plates.
A heat exchanger comprising:
- first and second heat conductive spaced apart plates with one of the plates being selectible to exchange more heat than the other of the plates with fluid flowing through the heat exchanger by choosing a direction of fluid flow through the exchanger;
- a heat conductive sheet disposed between the plates and having repeating ridges in thermal contact with the plates with successive ridges facing a different one of the plates and sections of the sheet between successive ridges being inclined with respect to the axis of fluid flow and containing at least one aperture with the at least one aperture extending between opposed surfaces of the section for passing fluid flow through the at least one aperture when fluid flows along the axis of fluid flow with fluid flow through the at least one aperture of a plurality of sections producing jets of fluid contacting one of the plates;
- and
- means for controlling the direction of fluid flow along the fluid flow axis in a first direction or a second direction opposite to the first direction to select which of the first and second plates exchanges more heat.
