Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
74 words
A tank part for connection to a header part to form a heat exchanger manifold, which tank part comprises an elongate generally channel-shaped member and at least one partition member fitted in the channel to extend transversely there accross, wherein the tank part is provided with inwardly deformed regions on opposite sides of the or each partition member in the longitudinal direction of the tank part to retain the or each partition in position.
Claim 2
Dependent Claim
24 words
A tank part according to claim 1 wherein the inwardly deformed regions comprise inwardly protruding dimples formed in the wall of the tank part.
Claim 3
Dependent Claim
19 words
A tank part according to claim 2 wherein two pairs of dimples are provided for the or each partition.
Claim 4
Dependent Claim
61 words
A tank part according to claim 1 or 2 wherein the channel member has longitudinal edge regions which are provided with upstanding portions at the location of the or each partition, regions of these upstanding portions constituting tabs which are bent inwardly on the opposite sides of the or each partition in order to hold an upper region thereof in position.
Claim 5
Dependent Claim
32 words
A tank part according to claim 4 wherein the upstanding portions comprise substantially rectangular tabs, corner regions of which are inwardly bent over on the opposite sides of the or each partition.
Claim 6
Dependent Claim
76 words
A tank part according to claim 4 wherein each upstanding portion is provided with a finger-like upward extension of the upstanding portion, constituting the tab which is bent inwardly towards the opposite tank edge region, substantially parallel to the plane of the partition, and wherein the finger-like tab at one edge region is disposed on one side of the partition with that of the opposite tank edge region disposed on the opposite side of the partition.
Claim 7
Dependent Claim
54 words
A heat exchanger manifold comprising elongate generally channel-shaped tank and header parts joined to form a tubular manifold body, and at least one transverse partition member fitted therein, wherein the tank part is provided with inwardly deformed regions on opposite sides, in the longitudinal direction of the manifold, of the or each partition member.
Claim 8
Dependent Claim
28 words
A heat exchanger manifold according to claim 7, wherein the inwardly deformed regions comprise two pairs of inwardly protruding dimples formed in the wall of the tank part.
Claim 9
Dependent Claim
56 words
A heat exchanger manifold according to claim 8, wherein the tank part has longitudinal edge regions which are provided with upstanding portions at the location of the or each partition, and regions constituting tabs bent inwardly from these upstanding portions on opposite sides of the or each partition to hold an upper region thereof in position.
Claim 10
Dependent Claim
78 words
A heat exchanger comprising at least one tubular manifold comprising separate tank and header parts joined along longitudinal edges thereof, said header part defining a plurality of apertures therein; a plurality of heat exchange tubes each extending through a respective aperture to communicate internally with the manifold; and at least one partition member disposed transversely in the manifold; wherein the tank part is provided with inwardly extending deformed regions on opposite sides of the or each partition member.
Claim 11
Dependent Claim
27 words
A heat exchanger according to claim 10, wherein the inwardly deformed regions comprise two pairs of inwardly protruding dimples formed in the wall of the tank part.
Claim 12
Dependent Claim
53 words
A heat exchanger according to claim 11, wherein the tank part has longitudinal edge regions which are provided with upstanding portions at the location of the or each partition, and tabs bent inwardly from these upstanding portions on opposite sides of the or each partition to hold an upper region thereof in position.
Claim 13
Independent Claim
82 words
A method of assembly of a tank part for a heat exchanger manifold of the type comprising separate tank and header parts joined to form a tubular manifold, comprising the steps of: a) providing a generally channel-shaped tank part and at least one partition member; b) fitting the or each partition member into the channel to extend transversely across the channel; and c) inwardly deforming the tank part on opposite sides of the or each partition member to retain this in position.
Claim 14
Dependent Claim
28 words
A method according to claim 13, wherein in step c) a punch tool directed at the outside of the tank part is employed to form inwardly protruding dimples.
Claim 15
Dependent Claim
40 words
A method according to claim 13 wherein the tank part is provided with portions upstanding from the longitudinal edges thereof, and in step c) regions of these upstanding portions are bent inwardly on opposite sides of the or each partition.
