Abstract
A heat exchanging coil that has at least one straight length of tube and at least one bend in the tube where fins are attached to the tube with unequal fin densities based upon tube orientation, and the fin density is different for straight lengths of tube than at bends in the tube.
Claims25
A coil for air-conditioning equipment, comprising:
- at least one tube having an outer wall surface, the at least one tube including at least one substantially straight section and at least one bend section;
- the at least one tube having a plurality of fins attached to the outer wall surface of the at least one tube;
- the fins being disposed in a spaced relationship from adjacent fins along the outer wall surface of the at least one tube;
- the fins disposed along the at least one straight section having a first fin density;
- the fins disposed along the bend section having a second fin density;
- and
- the first fin density is unequal to the second fin density.

A method of manufacturing a coil for use in air-conditioning equipment, comprising the steps of:
- providing at least one tube having an outer wall surface, the at least one tube to have at least one straight section and at least one bend section;
- attaching a first plurality of fins at a first fin density upon the outer wall surface of the at least one tube where the at least one straight section will be present;
- attaching a second plurality of fins at a second fin density upon the outer wall surface of the at least one tube where the at least one bend section will be present;
- and
- utilizing a first fin density that is unequal to the second fin density.
