下面换热器网的小编跟大家介绍浮动盘管换热器和U型管换热器的应用。
分析了浮动盘管换热器和U型管换热器的性能优缺点，并重点分析了浮动盘管换热器自动除垢功能和两种换热器在建筑热水系统中的应用，为使用方、设计方提供了选用的依据。
一、浮动盘管换热器 浮动盘管换热器是一种间接换热器。传热部分采用铜管，把传热管做成螺旋状浮动置于壳体内，所以称为浮动盘管。由于该换热器的传热管在壳体内水流过时可上下浮动高频振动，可使被加热水发生扰动，增强了传热效果。 浮动盘管主要分为沉浸式盘管换热器和喷淋式盘管换热器，其中沉浸式盘管换热器的盘管放在一个容器中，盘管和容器中各走一种流体进行热交换，为了使盘管充满液体，液体应从盘管下端送入，为了避免阻塞与水击，蒸汽宜从上方送入，在蒸汽冷凝的过程中使冷凝液积聚下端，如果需要的传热面大，可以将盘管相互呈同心圆状的并排排列。 1.浮动盘管换热器的优点 浮动盘管换热器采用纯铜浮动盘管和纯铜内胆，可防止“军团菌”的滋生。铜金属具备天然杀灭“军团菌”的作用，试验表明，大部分细菌在铜表面上不能存活，这也就是国外大部分宾馆，尤其是宾馆、医院的热水系统采用铜管、铜内胆的换热器原因之一。随着人们生活水平的提高，尤其是“非典”以后国家重视公共卫生安全，浮动盘管换热器无疑是更加卫生安全、技术成熟的设备。换热器的传热元件采用悬臂式浮动盘管结构。在加热过程中，由于盘管内蒸汽离心力的作用，使盘管产生一种高频浮动，促进被加热介质产生扰动，破坏了阻碍层流传热层滞留现象。同时由于盘管为悬臂自由端，胀缩自由，产生高频浮动，使碱性附着物自动脱离开管臂，形式自动脱垢的独有特性。
Heat exchanger network below small make up to introduce floating coil heat exchanger and the application of U tube heat exchanger.
Floating coil heat exchanger are analyzed and the U tube heat exchanger performance advantages and disadvantages, and focuses on analyzing the function of automatic removal of floating coil heat exchanger and the application of the two kinds of heat exchanger in building hot water system, for the use of the basis of a party, provided by the designer to choose.
A, floating coil heat exchanger Floating coil heat exchanger is a kind of indirect heat exchanger. Heat transfer part adopts copper pipe, the pipe made spiral floating in the casing, so called floating coil. Because of the heat exchanger of heat pipe in the shell may be floating up and down stream outdated within high frequency vibration, can make the heated water disturbance, to enhance the heat transfer effect. Floating coil is mainly divided into immersion coil heat exchanger and spray type plate heat exchanger, one of the immersion coil heat exchanger coil placed in a container, in the coil and the container go to heat a fluid, in order to make the coil tube filled with liquid, the liquid from the lower coil into, in order to avoid blocking and water hammer, the appropriate steam from above into, make the condensate to accumulate in the process of steam condensation bottom, if you need to heat transfer surface is big, can coil are arranged in a side by side of concentric rings to each other. 1. The advantages of floating coil heat exchanger Floating coil heat exchanger using pure copper floating coil and pure copper tank, can prevent the legionella bacteria breeding. Copper have natural kill legionella "role, the test shows that most of the bacteria can't survive on copper surface, which is most of the hotels abroad, especially in hotels, hospitals, hot water system using the copper pipe, copper tank heat exchanger. As people living standard rise, especially after "SARS" the state shall pay attention to public health security, floating coil heat exchanger is more health and safety equipment, mature technology. Heat exchanger heat transfer element USES the cantilevered floating coil structure. In the process of heating, due to the effect of coil steam centrifugal force, make the coil produces a high frequency of floating, promote the disturbance created by the heating medium, destroyed the block phenomenon of laminar flow heat transfer layer stranded. At the same time due to the coil for cantilever free end, swell-shrink freedom, produce high-frequency floating, alkaline attachments to automatically out of the open tube arm form unique characteristics of the automatic cleaning.
Heat exchanger network committed to the manufacture of heat exchanger, spiral plate heat exchanger, products of good quality and reasonable price, well received by customers in the industry, if you have any need to please contact us, we will give you the best solution!
