1.What is the basic working principle of heat exchanger?
Heat exchanger functions by transferring heat from higher to lower temperatures. Heat can thus be transferred from the hot fluid to the cold fluid if a hot fluid and a cold fluid are separated by a heat-conducting surface. The operation of a heat exchanger is governed by thermodynamics.
2.What are the four main types of plate type heat exchangers?
A plate heat exchanger is a compact type of heat exchanger that uses a series of thin plates to transfer heat between two fluids. There are four main types of PHE: gasketed, brazed, welded, and semi-welded.
3.Why is plate heat exchanger most efficient?
This design lends itself to very high heat transfer efficiency due to large surface area – much higher than a shell and tube heat exchanger taking up similar space.
4.How does a heater exchanger work?
Heat exchangers, metal shells, and tubes work by transferring heat from one place to another. When a furnace burns natural gas or propane fuel, its exhaust/combustion by-products (also known as flue gas) enter and travel through the heat exchanger.
5.What are the applications of plate heat exchanger?
In the food and beverage industry, plate heat exchangers are used for pasteurization, sterilization, and cooling of products like milk, juices, and sauces. - They are also employed for heating or cooling water for various food processing applications.
