Samsung patents air conditioner parts with fins that touch the tube

Samsung describes a heat exchanger design for air conditioners that uses flat tubes with fins on both sides. The filing details how specific parts of the top and bottom fins curve inward to physically touch the ends of the tube, creating a specific structural connection.

Why it mattersThis is a routine improvement to the internal components of cooling systems, likely aiming for better durability or heat transfer efficiency in standard appliances.

In the filing’s own words

An air conditioner includes a heat exchanger. The heat exchanger includes a tube having a flat tube form, and fins respectively provided on an upper surface and a lower surface of the tube. The fins include a plurality of ridges and a plurality of valleys alternately arranged along a longitudinal direction of the tube. A first fin provided on the upper surface of the tube includes a downwardly protruding portion that protrudes from a corresponding one of the plurality of valleys toward the lower surface of the tube and contacts one end of the tube in the flow direction of the fluid. A second fin provided on the lower surface of the tube includes an upwardly protruding portion that protrudes from a corresponding one of the plurality of ridges toward the upper surface of the tube and contacts the one end of the tube.

What exactly they claim (claim 1)

1. An air conditioner comprising: an outdoor heat exchanger; and an indoor heat exchanger, wherein at least one of the outdoor heat exchanger or the indoor heat exchanger includes: a first header into which a refrigerant for performing heat exchange with a fluid is introducible, a second header from which the refrigerant is discharged, a tube, having a flat tube form, into which the refrigerant in the first header is introduced such that the refrigerant flows through the tube to be discharged to the second header, wherein the tube has an upper surface which is parallel to a flow direction of the fluid and a lower surface opposite to the upper surface, a first fin on the upper surface of the tube and including: a plurality of ridges and a plurality of valleys alternately arranged along a longitudinal direction of the tube, and downwardly protruding portions that protrude from respectively corresponding valleys of the first fin toward the lower surface of the tube and that contact one end of the tube, and a second fin on the lower surface of the tube and including: a plurality of ridges and a plurality of valleys alternately arranged along the longitudinal direction of the tube, and upwardly protruding portions that protrude from respectively corresponding ridges of the second fin toward the upper surface of the tube and that contact the one end of the tube.
