Heat Exchangers - Research Paper Example   At the center of the heat exchanger lies two plates that are pinned together by pressing them and welding them together. There is a module whose function is to carry fluids in and out of the whole system. This combination is very efficient in offering high operating temperatures, and high pressure a factor that is vital in the heat exchange process.   The heat exchanger is able to function well without any gaskets. This means that it is able to work under these extreme conditions without any risk of leaking the fluid during the heat exchange process. Normally different types of heat exchangers are combined to come up with a more effective, cost friendly and efficient unit of the heat exchanger and the plate and shell heat exchanger is just but one example. This means that the fluids enter at the opposite ends of the unit enabling them to flow into the center of the exchanger. As the fluids come close to each other, there is an exchange of heat between the fluids.   As the flu id passes through the exchanger it either lose or absorb heat due to latent heat.  According to the nature of the heat exchange process, plates and shell heat exchangers are classified as indirect contact heat exchangers. The exchange of heat takes place by direct mixing of hot and cold fluids allowing transfer of heat and mass to take place simultaneously in a direct contact heat exchanger and such a unit is applicable only where the two fluids are either harmless when in contact or are desirable.
