FREE FROST HEAT EXCAHANGER
ABSTRACT
A new concept has emerged in the field of zero - emission vehicles : the cryogenic automobile . The cryogenic automobile uses nitrogen , stored in liquid state , as its working fluid . The liquid nitrogen is pressurized , then vaporized in an economizer through which the exhaust from the expander runs in counter flow . The resulting gaseous nitrogen is superheated in an ambient temperature gas which is injected into a quasi “ isothermal expander to produce t ....etc

Introduction

A device designed to transfer heat between two physically separated fluids; generally consists of a cylindrical shell with longitudinal tubes; one fluid flows on the inside, the other on the outside.

Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. In double-pipe exchange ....etc

ABSTRACT
MICRO-SCALE REGENERATIVE HEAT EXCHANGER
A micro-scale regenerative heat exchanger has been designed, optimized and fabricated for use in a micro-Stirling device. Novel design and fabrication techniques enabled the minimization of axial heat conduction losses and pressure drop, while maximizing thermal regenerative performance. The fabricated prototype is comprised of ten separate assembled layers of alternating metal-dielectric composite. Each layer is offset to minimize conduction losses and maximize heat transfer by boundary layer ....etc

ABSTRACT
Tar column recoiled E4509 in the phenol plant of HOCL found failed in service un like any other exchanger s in phenol manufacturing process .Each failure very high cost to HOCL in terms of production loss due to down time for maintence and due to the loss of therminol liquid to the process .the loss due to each failure found to be nearly RS 1.5 chore >the cost of tube bundle in SS-316 is ....etc
