一种高效率冷凝器 技术领域
本发明涉及冷凝器技术领域，具体为一种高效率冷凝器。
背景技术
冷凝器，为制冷系统的机件，属于换热器的一种，能把气体或蒸气转变成液体，将管子中的热量，以很快的方式，传到管子附近的空气中。冷凝器工作过程是个放热的过程，所以冷凝器温度都是较高的；发电厂要用许多冷凝器使涡轮机排出的蒸气得到冷凝。在冷冻厂中用冷凝器来冷凝氨和氟利昂之类的致冷蒸气。石油化学工业中用冷凝器使烃类及其他化学蒸气冷凝。在蒸馏过程中，把蒸气转变成液态的装置也称为冷凝器。所有的冷凝器都是把气体或蒸气的热量带走而运转的。制冷系统的高温高压氟里昂从压缩机出来后进入冷凝器中，向冷却介质释放出大量热量，被冷却液化。冷凝器按其冷却形式可分为三大类型：水冷式、风冷式、蒸发式及淋水式。
现有冷凝器重量大、热交换效率低、冷凝效果差，节能效果差。
