Claim 9

A heat exchange assembly as set forth in claim 7 wherein said pipe means and said at least one projection portion are formed integrally with each other in the form of an extrusion.

Claim 10

A heat exchange assembly as set forth in claim 1 wherein said carrier member is a plate member having a bent edge portion forming a connecting flange configuration which has a multiplicity of said openings thereby being adapted to secure said carrier plate member to at least one other adjacent carrier plate member.

Claim 11

A heat exchange assembly as set forth in claim 1 wherein said one of the carrier member and the securing means provided with said openings is harder than said other of the carrier member and the securing means adapted to be connected thereto.

Claim 12

A heat exchange assembly as set forth in claim 1 wherein at least one of said carrier member and said securing means comprises a material selected from aluminium, aluminium alloy, copper and copper alloy.

Claim 13

A heat exchange arrangement comprising a heat exchange assembly as set forth in claim 1 and further comprising support means adapted to support and mount said heat exchange assembly, said support means being secured to said heat exchange assembly by means of an arrangement of said openings.

Claim 14

A heat exchange assembly as set forth in claim 1, wherein the other of said carrier member and the securing means is formed from a material selected from aluminum, aluminum alloy, copper and copper alloy, said one of the carrier member and the securing means provided with said openings being formed of a harder material.

Claim 15

In a heat exchange assembly comprising a metal carrier means, a pipe means for carrying a heat exchange medium, the pipe means being supported by the carrier means, and metallic holding means for holding said pipe means to said carrier means, the improvement that comprises connecting the carrier means and the holding means together by a configuration comprising a plurality of openings in at least one of said carrier means and said holding means of the assembly, each said opening having an edge portion of jagged configuration projecting substantially normal to the adjacent surface of the component in which said openings are formed, the jagged edges of the openings being at least partially embedded in the material of at least one other of said carrier means and said holding means and material of said at least one other of said carrier means and said holding means being engaged in said openings in a rivet head-like anchoring configuration.

Claim 16

In a heat exchange assembly comprising a metal carrier means, a pipe means for carrying a heat exchange medium, the pipe means being supported by the carrier means, and metallic holding means for holding said pipe means to said carrier means, the improvement that comprises connecting the carrier means and the holding means together by a configuration comprising a plurality of openings in at least one of said carrier means and said holding means of the assembly, each said opening having an edge portion of jagged configuration projecting substantially normal to the adjacent surface of the component in which said openings are formed, the jagged edges of the openings being at least partially embedded in the material of at least one other of said carrier means and said holding means and material of said at least one other of said carrier means and said holding means being engaged in said openings in a rivet head-like anchoring configuration.

Claim 17

An assembly as set forth in claim 14 wherein said openings are provided in the carrier means.

Claim 18

An assembly as set forth in claim 14 wherein said openings are provided in the holding means.

Claim 19

An assembly as set forth in claim 14 wherein said holding means includes a portion integral with said pipe means and projecting laterally therefrom over at least a part of the length of said pipe means.

Claim 20

An assembly as set forth in claim 14 which includes an insert strip disposed between the carrier means and the holding means, the insert strip, carrier means and holding means being connected together by respective arrangements of said openings.

Claim 21

An assembly as set forth in claim 14, wherein the other of said carrier means and said holding means is formed from a material selected from aluminum, aluminum alloy, copper and copper alloy, said one of the carrier means and the holding means provided with said openings being formed of a harder material.

Claim 22

In a heat exchange assembly comprising a metallic carrier means; a pipe means for carrying a heat exchange medium; a metal auxiliary holding plate, the pipe means being supported between the carrier means and the auxiliary holding plate; and metallic holding means for holding said auxiliary holding plate to said carrier means, said holding means comprising an insert strip formed from a material harder than the materials forming the carrier means and auxiliary holding plate, said insert strip having jagged-edge openings pressed out of alternate sides thereof, each said opening having an edge portion of jagged configuration projecting substantially normal to the adjacent surface of the insert strip, the jagged edges of the openings being at least partially embedded in the materials of the carrier means and auxiliary holding plate, said materials being engaged in said openings in a rivet head-like anchoring configuration to thereby secure said carrier means and auxiliary holding plate to said insert strip.

Claim 23

In a heat exchange assembly comprising a metallic carrier means; a pipe means for carrying a heat exchange medium; a metal auxiliary holding plate, the pipe means being supported between the carrier means and the auxiliary holding plate; and metallic holding means for holding said auxiliary holding plate to said carrier means, said holding means comprising an insert strip formed from a material harder than the materials forming the carrier means and auxiliary holding plate, said insert strip having jagged-edge openings pressed out of alternate sides thereof, each said opening having an edge portion of jagged configuration projecting substantially normal to the adjacent surface of the insert strip, the jagged edges of the openings being at least partially embedded in the materials of the carrier means and auxiliary holding plate, said materials being engaged in said openings in a rivet head-like anchoring configuration to thereby secure said carrier means and auxiliary holding plate to said insert strip.
