Abstract
Official abstract text for this publication.
A fin tube heat exchanger 1 according to the present invention includes fins 31 and a heat transfer tube 21 penetrating through the fins 31 . A region that is surrounded by line segments connecting among two reference points BP and two leading edge reference points BPF is defined as a reference region. A region that is included in the reference region and located between an upstream reference line LU and a downstream reference line LD is defined as a specific region. Each fin 31 is provided with a cut-and-raised portion 12 having, in the specific region, another leading edge different from a leading edge 31 f . The cut-and-raised portion is formed by cutting and raising a part of the fin 31.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fin tube heat exchanger comprising: a plurality of fins each having a linear leading edge, the fins being arranged parallel to each other at a specified interval to form flow passages for air; and a heat transfer tube through which a medium that exchanges heat with the air flows, the heat transfer tube penetrating through the fins, wherein when: a direction in which the fins are arranged is defined as a height direction; a direction parallel to t…
