换热器用传热管以及使用了它的换热器
摘要：
本发明提供可提高水-制冷剂换热器的传热性能的换热器用传热管以及使用了它的换热器。本发明的换热器用传热管是作为构成换热器的水管来使用的波纹形状的传热管，在上述波纹管(10)的内表面上形成有螺旋状的内表面槽(2)，在设上述波纹形状的波纹槽(1)的深度为Hc、设波纹管外径为OD时，则满足0.04≤Hc/OD≤0.1的关系，在设上述内表面槽(2)的翅片高度为Hf、设管的最大内径为ID时，则满足0.022{30.7×(Hc/OD)+1.13}(-0.5)≤Hf/ID≤0.037的关系。
摘要（英）：

The invention provides a heat-transfer pipe for heat interchanger that improves heat transfer property of a water-refrigerant heat interchanger and the heat interchanger using the same. The heat interchanger of the invention is a undulatory one that forms water pipe of the heat interchanger. A spiral inner surface trough (2) is formed on inner surface of the sylphon bellowss (10); when orderingdepth of a corrugated trough (1) as Hc, maximal inner diameter of the sylphon bellowss as OD, a relationship 0.04 less than or equal to Hc/OD is met. When ordering fin height of the spiral inner surface trough (2) as Hf, maximal inner diameter of the sylphon bellowss as ID, a relationship 0.022{30.7*(Hc/OD)+1.13}(-0.5) less than or equal to Hf/ID less than or equal to 0.037 is met.
