Abstract

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

IPC Classes  ?

• B29C 45/14 - Injection moulding, i.e. forcing the required volume of moulding material through a nozzle into a closed mouldApparatus therefor incorporating preformed parts or layers, e.g. injection moulding around inserts or for coating articles
• F24S 80/30 - Arrangements for connecting the fluid circuits of solar heat collectors with each other or with other components, e.g. pipe connectionsFluid distributing means, e.g. headers
• F24S 10/70 - Solar heat collectors using working fluids the working fluids being conveyed through tubular absorbing conduits
• F16L 37/113 - Couplings of the quick-acting type in which the connection between abutting or axially-overlapping ends is maintained by locking members using a rotary external sleeve or ring on one part the male part having lugs on its periphery penetrating into the corresponding slots provided in the female part
• F24S 20/67 - Solar heat collectors integrated in fixed constructions, e.g. in buildings in the form of roof constructions
• F24S 25/60 - Fixation means, e.g. fasteners, specially adapted for supporting solar heat collector modules
• F24S 80/70 - Sealing means
• F28F 9/18 - Arrangements for sealing elements into header boxes or end plates by permanent joints, e.g. by rolling by welding
• F24S 80/00 - Details, accessories or component parts of solar heat collectors not provided for in groups
• B29K 21/00 - Use of unspecified rubbers as moulding material
• B29L 31/18 - Heat-exchangers or parts thereof
