Diseño, Construcción y Pruebas de un Intercambiador de Calor de Carcasa y Tubos para Laboratorio de Térmicas de la Facultad de Mecánica.

Abstract

A Heat Case –Pipe BEU Exchanger has been designed and constructed, according to the TEMA norms, where the involved fluids are steam in the pipes and water in the case. This equipment is designed to form part of the Thermal Lab at the Mechanics Faculty. The design has been divided into three phases: Thermal Design, Hydraulic Design and Mechanical Design. In the Thermal Design the case diameter and the diameter, number and length of the pipes were determined. In the Hydraulic Design the pressure equipment fall was calculated. Finally, in the Mechanical Design the thicknesses and materials of each exchanger part were established. The equipment consists of a digital gauge which provides simultaneously temperature data at the entrance and exit both of the steam and the water; moreover it has a linking option with a computer which through the use of the LabView program displays temperature behavior curves and all the values measured in a database formed automatically are obtained in an Excel calculus sheet. A Lab guide has been written consisting of Annexes which will serve as a support in the elaboration of the students as a consultation source.
