Application Of Gasket PLATE HEAT EXCHANGER
Author:
Heat exchanger is an essential device used in complex engineering systems related to heat
transfer processes in many industrial applications. Plate Heat Exchanger ( PHE ) is an important part of a condensing or evaporating system. Among many of factors which should concentrate on, the heat transfer and pressure drop is most important part during sizing and rating the performance of PHE. Due to the complex corrugated surface design flow is highly turbulent.
This makes design of plate heat exchanger using empirical correlations to deviate from actual. Sometimes flow medium cannot distribute uniformly which affects the performance of plate heat exchanger. The optimization problem is formulated as the minimization of the heat transfer area, subject to constraints on the number of channels, pressure drop, flow velocity and thermal effectiveness, as well as the exchanger thermal and hydraulic model. Nowadays PHE widely use in different industries such as chemical, food and pharmaceutical process and refrigeration. However in present work PHE applied in the dairy milk pasteurizer plant model. Milk is pasteurized for killing the bacteria and preserving milk for long time.

The natural laws of physics always allow the driving energy in a system to flow until equilibrium is reached. Heat leaves the warmer body or the hottest fluid, as long as there is a temperaturedifference, and will be transferred to the cold medium.
A heat exchanger follows this principle in its Endeavour to reach equalization. With a plate type heat exchanger, the heat penetrates the surface, which separates the hot medium from the cold one very easily. It is therefore possible to heat or cool fluids or gases which have minimal energy levels.
The theory of heat transfer from one media to another, or from one fluid to another is determined by several basic rules.
• Heat will always be transferred from a hot medium to a cold medium.
• There must always be a temperature difference between the media.
The heat lost by the hot medium is equal to the amount of heat gained by the cold medium, except for losses to the surroundings.
