Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
A radiator for heater-fans, particularly for passenger car air-conditioning systems, comprising a metal radiating pack (10) and manifolds (11-12) of a plastics material, and wherein said radiating pack is provided with head plates (17-18) for retaining the ends of the pack tubes . (13), characterized in that each head plate (17-18) is provided with a frame (110-120) of a plastics material which engages in undercut relationship the plate and forms a retaining seat for a cover (111-121) which is caused to adhere, through a peripheral ridge (NP) thereof, to said frame, whereto it is connected in sealed relationship by means of a flush weld.
Claim 2
Dependent Claim
104 words
A radiator for heater-fans, particularly for passenger car air-conditioning systems, comprising a metal radiating pack (10) and manifolds (11-12) of a plastics material, and wherein said radiating pack is provided with head plates (17-18) for retaining the ends of the pack tubes . (13), characterized in that each head plate (17-18) is provided with a frame (110-120) of a plastics material which engages in undercut relationship the plate and forms a retaining seat for a cover (111-121) which is caused to adhere, through a peripheral ridge (NP) thereof, to said frame, whereto it is connected in sealed relationship by means of a flush weld.
Claim 3
Dependent Claim
44 words
A radiator according to Claim 1, wherein the frames (110-120) associated with each head plate (17-18) have an L-like section profile defined by a horizontal portion in engagement with the related plate and a vertical portion forming the retaining seat for the related cover.
Claim 4
Dependent Claim
63 words
A radiator according to Claims 1 and 2, characterized in that each head plate (17-18.) comprises, fitted onto the edge thereof, a peripheral U-like gasket (20) of an elastomeric material to one lip (201) whereof said plastics material frame (110-120) is caused to adhere and to the other lip (202) whereof the inner edge (B) of said cover (111-121) is caused to adhere.
Claim 5
Dependent Claim
49 words
A radiator according to the preceding Claims, wherein the depth of each cover (111-121) is selected to be slightly greater than the corresponding height of the frame (110-120) such that, following mutual connection by welding, said frame and cover deform the peripheral gasket (20) to provide a tight seal.
Claim 6
Dependent Claim
34 words
A radiator according to the preceding claims, wherein the surfaces of the frame (110-120) and covers (111-121) contacting the gasket (20) are provided with ridges adapted to deform said gasket for a tight seal.
Claim 7
Dependent Claim
63 words
A radiator according to the preceding claims, wherein the cover (111) of one manifold (11) is provided with connection fittings (23-24) and a septum (25) which seaparates and seals off two chambers (26-27) . respectively for delivering and recycling the fluid circulated through the radiating pack, and wherein the septum cooperates with a gasket (28) for the purpose of sealing off said chambers.
Claim 8
Dependent Claim
29 words
A radiator according to Claims 1 and 2, wherein between each head plate (17-18) and related plastics material frame (110-120) there is interposed an adhesive or sealing layer (SK).
Claim 9
Dependent Claim
32 words
A radiator according to Claims 1 and 2, wherein the peripheral portion of each head plate (17-18) is embedded by co-pressing in the horizontal portion of the related plastics material frame (110-120).
