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.
