Heat exchangers

A heat exchanger comprising:

• a header:
• a tank;
• a plurality of tubes arranged to connect the header and the tank;
• a plurality of fins for interspacing the tubes, the fins extending along the length of the tubes, wherein the tubes comprise at least one outermost tube, the outermost tube having an outer edge and having a first fin on the outer edge;
• a sideplate extending between the header and the tank and having a web portion engaging the first fin, the sideplate having braze cladding on one face of the web portion;
• wherein the web portion has a thickness, and the sideplate has a flange of double said thickness, the flange extending beyond the web portion to form a fin support portion.

A heat exchanger comprising:

• a first manifold having a length and a transverse width;
• a second manifold;
• a heat exchanger core having a thickness less than said width, the core comprising a plurality of tubes and a plurality of fins, wherein the tubes comprise at least one outermost tube having an outer edge, the outermost tube having a first fin on the outer edge;
• a sideplate disposed between the manifolds and having a web portion having one face engaging the first fin, braze cladding being disposed on the one face, and wherein the sideplate has a first portion having a first width substantially equal to the core thickness and a second portion having a second width greater than the first width;
• wherein the web portion has a first thickness and the second portion of the sideplate has a flange of double said first thickness, the flange extending beyond the web portion to form a fin support portion.

A sideplate for a heat exchanger comprising:

• two inner side wall portions, each inner side wall portion having a first end and a second end;
• an elongate generally planar web portion extending between the first end of each inner side wall portion;
• and
• two outer side wall portions, each outer side wall portion extending from the second end of each inner side wall portions;
• wherein the inner side wall portions and the outer side wall portions are substantially parallel to each other, the inner side wall portions and the outer side wall portions extending substantially perpendicular to the web portion in a first direction, and at least one of the outer side wall portions extending perpendicular to the web portion in a second direction.

A heat exchanger comprising:

• a header;
• a tank;
• a plurality of tubes connecting the header and the tank, the plurality of tubes including at least one outermost tube having an outer edge with a first fin;
• a plurality of fins extending along the length of and interspacing the plurality of tubes;
• and
• a sideplate extending between the header and the tank, the sideplate having a web portion and a first flange, the web portion having a thickness and braze cladding on a first face that engages the first fin, the first flange having double said thickness and extending beyond the web portion to form a fin support portion.
