Aluminum Refrigerant Distributors are made from 6061-T6 aluminum, and suitable for brazing.
Aluminum brazing requires close temperature control because of the narrow range of melting points between the filler metals and the base metal.
Aluminum Alloy 6061
Changzhou City, China
A method and system are described for a refrigerant distributor, and for attaching the distributor tubes to an evaporator coil.
A short tube can be inserted into the bell end of a tube and the hell end can be crimped around the short tube to lock it into place. The short tube preferably has a bead or widened shaft around which to crimp the bell.
The disclosure is particularly beneficial for aluminum-based components because aluminum is more susceptible to blockages or leaking due to problems from brazing.
