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.
