초록 ▼

A heat exchanger and method of making same is disclosed. The heat exchanger is particularly useful for cooling automotive engine oil or transmission fluid, the exchanger being located inside the radiator or other part of the engine cooling system. The heat exchanger is made from a plurality of stacked plates formed of cladded metal, the plates being assembled into face-to-face pairs, each pair having a turbulizer located therein. The plates also have outwardly disposed dimples which are in contact when the plates are arranged back-to-back. The turbulizer is thicker than the spacing between the assembled plates prior to brazing the assembly, and a portion of the peripheral edges of the turbulizer is deformed or crimpled during assembly.

A heat exchanger comprising: a plurality of stacked plates arranged in face-to-face pairs, each of said face-to-face pairs including first and second plates, the first plate having a planar central portion, a raised peripheral edge portion located above and in a plane parallel to the central portion, a transition portion between the central and edge portions, and opposed end bosses located below and in a plane parallel to the central portion; the second plate of each face-to-face pair having a peripheral edge portion joined to said first plate peripheral edge portion, a central portion spaced from the first plate central portion, a transition portion between the central and edge portions, and opposed end bosses located above and in a plane parallel to the second plate central portion; the first and second plate central portions having opposed cladding layers formed thereon; a planar expanded metal turbulizer located between the first and second plates of each face-to-face plate pair, the thickness of the turbulizer being generally equal to the distance between the first and second plate central portions without the cladding layers; the first and second plate central portions having a plurality of spaced-apart, outwardly disposed dimples formed therein, the dimples extending equidistant with the end bosses; the first plate of one plate pair being located back-to-back with the second plate of an adjacent plate pair, the respective dimples and end bosses being joined together; and each plate pair defining inlet and outlet openings for the flow of fluid through the plate pair past the turbulizer. A heat exchanger comprising: a plurality of stacked plates arranged in face-to-face pairs, each of said face-to-face pairs including first and second plates, the first plate having a planar central portion, a raised peripheral edge portion located above and in a plane parallel to the central portion, a transition portion between the central and edge portions, and opposed end bosses located below and in a plane parallel to the central portion; the second plate of each face-to-face plate pair having a peripheral edge portion adapted to mate with first plate peripheral edge portion, a central portion spaced from the first plate central portion, a transition portion between the central and edge portions, and opposed end bosses located above and in a plane parallel to the second plate central portion; a planar turbulizer located between the first and second plates of each face-to-face plate pair, the thickness of the turbulizer being generally equal to the distance between the first and second plate central portions; the first and second plate central portions having a plurality of spaced-apart, outwardly disposed dimples formed therein, the dimples extending equidistant with the end bosses; the first plate of one plate pair being located back-to-back with the second plate of an adjacent plate pair, the respective dimples and end bosses being joined together; each plate pair defining inlet and outlet openings for the flow of fluid through the plate pair past a turbulizer; and the peripheral edge portions of each plate pair being joined together by a process comprising the steps of: arranging the plates of each plate pair with a hollow space therebetween; inserting the turbulizer into said hollow space, the turbulizer being of such thickness that the mating peripheral edge portions are spaced apart; heating and partially melting the plate pair while said mating peripheral edge portions are still spaced apart; and compressing the turbulizer by pressing the plate pair together thereby melting the turbulizer into said central portions drawing the mating peripheral edge portions together.
