Abstract
A dog-bone type heat exchanger having a plurality of fin members for dissipating heat. Each of the plurality of fin members includes a pair of offset surfaces interconnected by a sloped interconnecting surface. The plurality of fins members may be spaced apart at a distance that is less than, equal to, or more than the offset distance between the pair of offset surfaces on each fin member, thereby maximizing the mixing of air flow and the conductive heat transfer of the heat exchanger through an impinging effect.
Claims3
A method of assembling a dog-bone type heat exchanger, said method comprising:
- providing a base member having a plurality of spaced support members coupled thereto forming support channels therebetween;
- providing a pair of fin members each having a first surface and a second surface interconnected by a first sloped interconnecting surface, a plane of said first surface being offset from a plane of said second surface, at least said first surface having a plurality of slots formed therethrough, each of said plurality of slots having a pair of generally circular portions and an intermediate portion;
- inserting each of said pair of fin members into said corresponding support channels formed in said base member and retaining each of said pair of fin members along only said interconnecting surface using only said support channel;
- providing a continuous tube having a plurality of reverse bends forming a plurality of parallel tube runs;
- and
- inserting each of said plurality of reverse bends through a corresponding one of said plurality of slots formed in said pair of fin members.
