A double pipe heat exchanger is a sort of heat exchanger which includes concentric pipes parted through a mechanical closure. The name of this heat exchanger indicates that it makes use of pipes to exchange heat among fluids. One pipe has hot fluid whilst the opposite pipe has cold fluid. These two fluids do not mix with each other as they are separated by pipes. This heat exchanger is likewise known as a jacketed u-tube, jacketed tube, hairpin, and pipe-in-pipe heat exchanger.
The double pipe heat exchanger has a small pipe this is surrounded by some other huge pipes. One fluid glide withinside the small pipe, and the opposite fluid acts through the annulus among the 2 pipes. The internal wall of the small pipe is the heat switch surface. The complete warmness switch system takes vicinity withinside the huge tube. In this way, the internal pipe works as a conductive barrier. The outside facet consists of fluid gliding thru the tube facet or inside. This heat exchanger might also additionally have one pipe or a package deal of pipes (however decrease than 30 pipes). The huge pipe has decreased by 2 hundred mm in diameter. In a few conditions, the internal pipe has vertical fins to enhance the heat switch coefficient among operating fluids.
Double pipe heat exchangers are used for small heat switch areas (e.g., 14 m2). The collection connection to elevate the heat switch place wishes greater area and greater accessories, which results in a better strain loss. In addition, it isnâ??t always viable to boom the number of fluid passages on each side. This heat exchanger isnâ??t always exceptionally appropriate for grimy drinks due to the fact the grimy liquid will clog it, and the cleansing of this exchanger could be very hard. The essential benefit of the double pipe warmness exchanger is that it has a smooth operation and easy design.
Copper finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the external or internal surface of the heat exchange tube), so as to achieve the purpose of improving the heat exchange efficiency. The overall finned tube has no contact thermal resistance, good heat transfer performance, high strength, thermal and mechanical vibration, and good thermal expansion performance.
A Heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. Fi-Way is dedicated to deliver the requirement of customers as per their needs of different types of heat exchangers
