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. This software has thermal design calculations for shell and tube condensers, vertical/horizontal condensers. Gasketed Plate Heat Exchanger Design This software has a step by step thermal analysis and calculations for the design of Gasketed plate heat exchangers. Double Pipe Heat Exchanger Design

This project work is based on design and thermal analysis of double pipe heat exchanger. Double pipe Heat exchangers (often also referred to as вЂњdouble pipesвЂќ) are characterized by a construction form which imparts a U-shaped appearance to the heat exchanger. In its classical

Dec 21, 2014В В· In an Excel spreadsheet for thermal design of a double pipe heat exchanger, the heat exchanger equation can be used to calculate the required heat exchanger area for known or estimated values of the other three parameters, Q, U, and О”T lm. Each of those parameters will be discussed briefly in the next three sections. Convective heat transfer from the outer tube wall to the outside fluid. Heat exchangers are typically classified according to flow arrangement and type of construction. The simplest heat exchanger is one for which the hot and cold fluids move in the same or opposite directions in a concentric tube (or double-pipe) construction.

HEAT TRANSFER Mechanisms of Heat Transfer: (1) Conduction where Q is the amount of heat, Btu, transferred in time t, h k is the thermal conductivity, Btu/[h ft2 (oF/ft)] A is the area of heat transfer normal to heat flow, ft2 T is the temperature, oF x is the thickness of the conduction path, ft.
