摘要: This heat exchanger is provided with refrigerant tubes (16a) in which (RF) that absorbs from air (AR) flows, and defrosting medium (43a) cooling water (WT) for supplying flows. Two fins (50) positioned on either side of a tube have protruding sections (50b) protrude toward the upstream flow (AR). The form gap (50d) enables melt produced by to tubes. can be alternatively an line. such manner as enable introduced sides section passage, even if end (50c) facing blocked lump frost.
