the addition of fins to such double pipe heat exchangers reduces the Nu sselt Number; however the corresponding heat transfer rate increases owing to the increase in the overall heat transfer per
A double-pipe heat exchanger is the simplest type of heat exchanger and can operate with co-current (Figure 1) or counter-current (Figure 2) flow.The design consists of a single small pipe (tube-side) inside of a larger one (shell-side).A co-current heat exchanger is most commonly used when you want the exiting streams to leave the exchanger Advantages Disadvantages Suited to high pressure applications.Limited to low heat duties requiring sur Standardization,simplifies maintenance, Flow pattern is strictly counterflow; th Flexibility,units can be added or remov As units are added on the possibility of Modular type construction.Jan 19 2021What is a double pipe heat exchanger - WeBBusterZAll About Double Pipe Heat Exchangers - What You Need ToThe double pipe heat exchanger is one of the easiest designs to fabricate,add on to,and repair thanks to its simple design.They have some unique advantages over some of the more complicated heat exchanger designs,as well as some important disadvantages,so this article will show buyers when they should and shouldnt consider uSpecifications,Selection Criteria,and ApplicationsSummaryThe double pipe heat exchanger,as seen above,is perhaps the simplest heat exchanger in industry.As a result,there are many,many options to choose from to buy,or they can be made customto fit the specific needs of the project.They are most useful for small-capacity applications where the total heat transfer surface area is < 500 square feet,as it is more cost-effective per unit-surface-area to use another design past this amount.When specifying a double-pipe heat exchanger for a project,consider the working fluiSee more on thomasnetDOUBLE-PIPE HEAT EXCHANGER - University of UtahAug 26,2002·The double-pipe heat exchanger is one of the simplest types of heat exchangers.It is called a double-pipe exchanger because one fluid flows inside a pipe and the other fluid flows between that pipe and another pipe that surrounds the first.This is a concentric tube construction.
