A double pipe heat exchanger is a heat exchanger that uses two pipes to exchange heat between two fluids. One pipe has hot fluid while the other pipe has cold fluid. This heat exchanger is also called a jacketed U-tube, jacketed tube, hairpin, and pipe-in-pipe heat exchanger.
12 Μαρ 2023 · A double-pipe heat exchanger known also as a hairpin-type exchanger (due to its U-shape bend resembling a hairpin) is made up of two concentric pipes [1]. The outer pipe (shell-side) is usually a bare pipe, and the inner pipe (tube-side) is either a bare pipe or more commonly a pipe with longitudinal fins, providing additional surface area for ...
2 Οκτ 2023 · The double pipe heat exchanger is one of the basic kinds of exchangers with a very flexible configuration. There are two types of counterflow or parallel flow for this type that are the basis of design and calculation for determining pipe size, length, and a number of bends.
A double pipe heat exchanger is one of the simplest types of heat exchangers used in various industries for heat transfer applications. As the name suggests, it consists of two pipes, one within the other. The inner pipe carries the hot fluid, while the outer pipe carries the colder fluid.
Double-pipe exchangers is the generic term covering a range of jacketed 'U' tube exchangers normally operating in countercurrent flow of two types: True Double Pipes: Single inner pipe formed into a removable 'U' or element, with either longitudinal fins or centralizing supports.
Learn how a double pipe heat exchanger works with worked examples for tube in tube or double pipe heat exchangers as well as appl...
5 Ιαν 2017 · One of the most simple and applicable heat exchangers is double pipe heat exchanger (DPHE) (Fig. 1). This kind of heat exchanger is widely used in chemical, food, oil and gas industries.
25 Μαΐ 2024 · The double pipe heat exchanger, also known as a hairpin or jacketed pipeline, is one of the simplest forms of heat exchangers. It is commonly used in industries for the transfer of heat energy between two fluids. This exchanger consists of two concentric pipes, one inside the other.
5 Ιαν 2017 · Double pipe heat exchangers are widely used in different industries due to simplicity. Geometry modifications have led to higher effectiveness in double pipe heat exchangers. Using nanofluids in double pipe heat exchangers has presented higher heat transfer rates.
In Process Ecology’s engineering design practice, we have sized several double-pipe heat exchangers, and below we share a step-by-step guide for the design of these units. Commonly in these types of calculations, you have a known fluid that is being cooled or heated.
