The utility model discloses a heat exchange tube and includes its evaporative condenser, the heat pipe is an ellipse, the short axis of the heat exchanger tube length is a, the heat exchange tube of long axis length is B, the heat pipe wall thickness is e, the range of a 10 15mm the range of B, 18 24mm, E in the range from 0.5 1.5m. The evaporative condenser includes a single coil, and the coil includes a plurality of heat transfer tubes. Compared with the conventional circular heat exchange tube, the elliptic heat exchanger tube of the utility model has better water film wrapping outside the heat exchange tube and higher heat exchange efficiency. Compared with the circular tube of the conventional evaporative condenser, the heat transfer area of the unit volume is increased, and the heat transfer efficiency is effectively improved. Moreover, the outer dimension of the evaporator condenser is reduced, and the box panel material is saved. At the same time, the unit power ratio is lower than the exhaust heat, and the energy consumption is reduced. The size of the evaporator condenser box is suitable for container transportation, which greatly reduces the transportation and installation cost.

换热管及包括其的蒸发式冷凝器
本技术涉及一种换热管,尤其涉及一种蒸发式冷凝器用的换热管以及包括该换热管的蒸发式冷凝器。
技术介绍
自20世纪80年代,我国开始引进蒸发式冷凝器,蒸发式冷凝器主要应用于冷库大型氨制冷系统,在其他领域应用较少。近30年来,随着蒸发冷凝技术的开发,各种新型蒸发式冷凝产品问世,蒸发式冷凝器在结构上发生了很大改变,在换热效率上相对其他水冷和空冷冷凝器也有了一定的优势,蒸发式冷凝器系列产品逐渐应用于中央空调、制药、化工、石油等诸多行业。相比其他冷却设备来说,由于地理位置的限制和我国水资源缺乏,目前蒸发式冷凝器设备在应用中占的比例并不是很高,主要集中于沿海地区,但是其高效换热的特点,使蒸发式冷凝器具有十分良好的应用前景。但是,由于蒸发式冷凝器的外形结构尺寸相对较大,不适合集装箱整体吊装和运输,因此,在生产企业生产检验合格后,需要将蒸发式冷凝器拆卸为几部分进行运输,到现场后再次进行安装施工。由此带来的运输成本较高,同时更重要的是,安排安装施工人员到现场成本较高,而且现场的施工由于空间的限制和现场设备的不充足,带来一系列安装施工的问题。这一问题一直是 ...
