Title:

FIN-TUBE HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE USING SAME

Document Type and Number:

WIPO Patent Application WO/2013/161193

Kind Code:

A1

Abstract:

This fin-tube heat exchanger is provided with: a plurality of fins (1) for passing an air current (100), the fins (1) having cut-and-raised parts (4); and a plurality of heat transfer pipes (2) inside which a fluid flows, the heat transfer pipes (2) penetrating through the plurality of fins (1). The cut-and-raised parts (4) are provided only on the downstream side of the air current (100) from a center of the closest heat transfer pipe (2), and are formed so as to be inclined with respect to the air current (100). The heat flux is therefore made uniform, water that is deposited on the fins (1) is smoothly channeled downward by the cut-and-raised parts (4), frost formation on the fins (1) can be minimized and drainage properties can be enhanced, and excellent heat transfer performance is obtained.
