A heat exchanger () includes an inlet connector () having a flat joint surface () and an outlet connector () having a flat joint surface (). The heat exchanger () also includes a round tube (). The round tube () includes an inlet aperture (), an outlet aperture () and flat surfaces () adjacent each of the inlet aperture () and the outlet aperture (). The flat joint surface () of the inlet connector () is coupled to the flat surface () adjacent the inlet aperture () and the flat joint surface () of the outlet connector () is coupled to the flat surface () adjacent the outlet connector ().

Heat exchanger

A tube interface () includes a first tube () and a second tube (). The first tube () has an oblong opening () exhibiting a first major dimension (), and the second tube () has an oblong end () exhibiting a second major dimension (). The oblong end () of the second tube () is inserted into the oblong opening () so that the second major dimension () is aligned with the first major dimension (). The second tube () is turned in the oblong opening () to move the second major dimension () out of alignment with the first major dimension () of the oblong opening () to secure the second tube () to the first tube () prior to brazing.

A heat exchanger evaluation system () includes a refrigeration subsystem () and a platform () in communication with the subsystem () for attachment of a heat exchanger (). The system, () further includes a thermal imaging camera () and a monitor (). A method () entails routing a fluid () through the heat exchanger () via the refrigeration subsystem (). The camera () detects the temperature variation across the heat exchanger () as the fluid () flows through the heat exchanger, and provides successive thermal images representing the temperature variation responsive to the flow of the fluid (). The thermal images are utilized to determine an efficacy of the flow through the heat exchanger (). In particular, a determination can be made as to whether the flow deviates from a pre-determined flow path () of the fluid () through the heat exchanger.

A receiver () for a condenser system () includes a body () in fluid communication with a header () of the condenser system (). A first cap () is coupled to an end () of the body () and has a saddle portion () coupled to the header (). The receiver () further includes a tube section () coupled to a second end () of the body. A second cap () is removably interconnected with the tube section () following insertion of a service cartridge () into the body (). The service cartridge () includes a substantially-rigid tubular member () having rib members () radially extending from an outer surface () of the tubular member (). Covers (), each having openings (), are coupled to opposing ends of the tubular member (). The service cartridge () includes multiple features for drying, filtering, and/or leak detection.

Receiver and service cartridge for a condenser system

A receiver () in a condenser system () includes a body () in fluid communication with a header () of the condenser system (). A service cartridge () is insertable into an interior cavity () of the body (). The service cartridge () includes a substantially-rigid tubular member (). Covers (), each having openings (), are coupled to opposing ends of the tubular member (). A spindle () is non-detachably coupled to each of the first cover () and a cap (). The cap () is configured for threaded attachment to a service end of the body () of the receiver (). Refrigerant 150 is received by the tubular member () via the first openings (), and is discharged from the tubular member () via the second openings (). The service cartridge () includes multiple features for drying, filtering, and/or leak detection.

Service cartridge for a receiver in a condenser system

A condenser system ( ) includes a first header ( ), a second header ( ), and parallel tubes ( ) extending between the headers ( ). A receiver ( ), affixed to the second header ( ), is in fluid communication with the second header ( ). The receiver includes a body ( ), a first cap ( ) coupled to the body ( ), and a second cap ( ) coupled to the body. The condenser system ( ) is subjected to a one-shot brazing process that nondetachably couples the receiver ( ) to the second header ( ), and concurrently nondetachably couples the first and second caps ( ) to the receiver body ( ). A desiccant system ( ) and/or filter ( ) may be optionally installed into the receiver ( ) prior to brazing.

A receiver dryer mounting bracket ( ) for a condenser system ( ) includes a body ( ) and an arm ( ) coupled to and extending from the body ( ). The body ( ) has an opening ( ) and seat sections ( ) positioned at opposing ends of a length of the opening ( ). Flanges ( ) on inlet and outlet pipes ( ) of the condenser system ( ) are seated in the seat sections ( ). An arcuate crimp section ( ) of the body ( ) is compressed to secure the inlet and outlet pipes ( ) in respective ones of the seat sections ( ) to form a pipe assembly ( ). The pipe assembly ( ) is coupled to a header ( ) of the condenser system ( ) prior to furnace brazing, and a receiver dryer ( ) is subsequently mounted to the bracket ( ).
