摘要： A fin-tube type heat exchanger has parallel heat transfer tubes and a stack of a plurality of plate fins mounted on the tubes. Heat exchange is conducted between a first fluid flowing through the tubes and a second fluid flowing through the stack across each of the fins. Each fin has flat tube-mounting portions spaced in the longitudinal direction of the fin and formed with tube-mounting holes and a louver section disposed between each adjacent pair of tube-mounting portions. The louver section has elongated slats extending longitudinally of the fin and having side edges each spaced from an adjacent side edge of an adjacent slat. The slats are classified into two groups in respect of the cross-sectional shape. The slats of one group have generally flat cross-sections to reduce the resistance of the fin to the flow of the second fluid through the stack and are disposed in planes offset from the plane of the tube-mounting portions. The slats of the other group have V-shaped or inverted V-shaped cross-sections to increase stiffness of the fin in the longitudinal direction thereof.
摘要翻译：翅片管型热交换器具有平行的传热管和安装在管上的多个板翅片的堆叠。在流过管的第一流体和跨过每个翅片流过堆叠的第二流体之间进行热交换。每个翅片具有在翅片的纵向间隔开的扁平管安装部分，并且形成有管安装孔和布置在每个相邻的一对管安装部分之间的百叶窗部分。百叶窗部分具有从翅片纵向延伸的细长板条，并且具有与相邻板条的相邻侧边缘间隔开的侧边缘。板条在横截面形状上分为两组。一组的板条具有大致平坦的横截面，以减小翅片对通过堆叠的第二流体的流动的阻力，并且设置在从管安装部分的平面偏移的平面中。另一组的板条具有V形或倒V形横截面，以增加翅片在其纵向上的刚度。

摘要： A heat exchanger, e.g. that used in an air-conditioner, having a plurality of spaced plate-fins with narrow distance in parallel and a plurality of heat transfer pipes passing through said fins, said fins being coated with an aqueous coating composition comprising 100 parts by weight of a resin composition for water paint in solids content, 5 to 95 parts by weight of a surface active agent and 5 to 65 parts by weight of synthetic silica and baked at a temperature of 120.degree. C. to 200.degree. C. for 10 to 40 minutes to give a coating film of 3 to 20 .mu.m, has excellent hardness and corrosion resistance without damaging hydrophilic properties.
