一种铜合金材料的换热板片
摘要：
本发明提供了一种板式换热器中使用的换热板片，所述换热板片中设置至少一个分流部件，所述分流部件将流经换热板片的换热流体的流动路径分成至少两个分流流道，分流部件设置开口，使得所述的换热板片中的分程流道为串联结构，从而使换热流体在换热板片上形成S形流道；所述的换热板片采用铜合金材料，所述铜合金由铜、铁、锰、铈、镁、锡、银、铬及其他辅材加工而成，所述铜合金中各成分所占重量百分比分别为：铜71.2％～82.5％、铁3.3％～4.5％、锰1.1％～2.5％、铈0.35％～0.45％、镁0.77％～1.3％、锡0.028％～0.14％、银0.06％～0.09％、铬0.3％～0.9％，剩余为辅材。本发明的换热板片铜合金具有耐高温、导热系数高的特性，并且大大改善了抗变形能力和耐磨性。
摘要（英）：

The invention provides a heat exchange plate used in a plate heat exchanger. At least one flow dividing component is arranged in the heat exchange plate and used for dividing the flowing path of heat exchange fluid flowing through the heat exchange plate into at least two flow dividing flow channels, the flow dividing components are provided with openings so that the flow dividing flow channels in the heat exchange plate can be of a serial structure, and thus an S-shaped flow channel is formed by the heat exchange fluid on the heat exchange plate. By means of the heat exchange plate, the demand for different section areas of cold side fluid and hot side fluid is met, the assembling mode of single-side pipe connection is adopted for the plate heat exchanger formed by assembling plates, much installation and maintenance cost can be saved, meanwhile, the heat exchange efficiency is high, and the purposes of energy conservation and environmental friendliness are achieved.
