An apparatus formed by a roll bonding or extrusion process providing continuously tapered or continuously expanding roll bonded refrigerant and air conduits or incrementally sized extrudate refrigerant conduits to optimize internal heat flow throughout the refrigerant circuit. The air conduits are formed integrally with and adjacent to the refrigerant conduits. The air conduits are lanced forming a plurality of fin strips having a plurality of miniature strip fins with slits thereinbetween arranged perpendicular to the direction of air flow. Air circulates through the air conduit and slits, and around the fins and the refrigerant conduit to increase heat transfer between the air and the refrigerant. The apparatus can be utilized to provide a one piece composite refrigeration unit comprising a condenser, an evaporator, an umbilical circuit strip integrally connecting the condenser and the evaporator, wherein the umbilical strip includes a suction tube and a liquid line capillary metering tube.
A roll bonded integral tube and strip fin heat exchanger circuit comprising:
An extruded integral tube and strip fin heat exchanger circuit comprising an extrudate having at least one refrigerant conduit and at least one air conduit sharing at least one common interior sidewall, said air conduit being lanced forming at least two fin strips having a plurality of strip fins with slits thereinbetween, whereby air circulates through said air conduit and said slits, and around said fins and said refrigerant conduit to increase heat transfer between said air and said refrigerant conduit.
An extruded integral tube and strip fin heat exchanger circuit comprising an extrudate having at least one refrigerant conduit having a generally rectangular cross-sectional shape and at least one air conduit sharing at least one common interior sidewall, said air conduit being lanced forming at least two fin strips having a plurality of strip fins with slits thereinbetween, whereby air circulates through said air conduit and said slits, and around said fins and said refrigerant conduit to increase heat transfer between said air and said refrigerant conduit.
