Abstract
A heat exchanger tubing includes at least a pair of tubes (1) that are connected to and separated by a connecting member (3). The connecting member (3) has a number of fin projections (7) extending at an angle from the member (3), each fin projection (7) having an opening (9) to allow air to pass through the member. The tubing is arranged between headers (21) of a heat exchanger (20) in an angled configuration so that the fins align with the air flow (A) passing across the tubing for enhanced heat exchange. The connecting member (3) can also be multivoid tubing (41), which has the fin projections for heat transfer or uses the passageways (49) in the multivoid tubing and fluid flowing through the channels for heat exchange.
Claims10
A tubing configuration for use in a heat exchanger comprising:
- at least two tubes, each tube having at least one channel therein for the passage of a heat exchange fluid;
- and
- a connecting member arranged between and connected to the two tubes, the connecting member being substantially parallel to the tubes and further comprising:
- a plurality of spaced apart fins, each extending at an angle from a surface of the connecting member;
- and
- a plurality of spaced apart openings extending through the connecting member, each spaced apart opening associated with one of the respective spaced apart fins,
- wherein each of said spaced apart fins are generally aligned such that the anticipated direction of the airflow through the heat exchanger passes through the substantially spaced apart openings.
The tubing arrangement of clam 1, wherein the plurality of the spaced apart fins and openings extend along the connecting member in a longitudinal direction, a lateral direction or a combination of both directions.
