What is the working principle of plate heat exchanger?
With a plate heat exchanger, heat cuts through the surface and separates the hot medium from the cold. Thus, heating and cooling fluids and gases use minimal energy levels. The theory of heat transfer between mediums and fluids happens when: Heat is always transferred from a hot medium to a cold medium.
What is the function of a heat exchanger?
Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact.
How does a plate and shell heat exchanger work?
Plate-and-shell exchangers combine the pressure and temperature capabilities of a cylindrical shell with the excellent heat transfer performance of a plate heat exchanger. The round plates ensure an even distribution of mechanical loads, without the stress concentrations that occur in the corners of rectangular plates.
Why is plate heat exchanger used?
The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. Welded, semi-welded and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required.
What is plate type heat exchanger?
A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.
What are the advantages of plate heat exchanger?
Advantages of Plate Heat Exchangers; A lower cost option wherever stainless steel is required. Higher operating pressure capabilities. Higher temperature capabilities. Ideal for small district heating, beverage cooling, food and pharmaceutical production and low duty oil cooling applications.
Where are plate heat exchangers used?
Some of the applications where this high efficiency is evident when using the Graham Brazed or Gasketed Plate Heat Exchangers are:
- Water heaters.
- Cooling tower isolation.
- Free cooling.
- Waste heat recovery.
- Heat pump isolation.
- Thermal (ice) storage systems.
Plate Heat Exchanger Working Principle. A plate exchanger consists of a series of parallel plates that are placed one above the other so as to allow the formation of a series of channels for fluids to flow between them. The space between two adjacent plates forms the channel in which the fluid flows.

How many in-out ports are there in a plate heat exchanger?
In standart plate heat exchangers, there are 4 in-out ports and two of them are for heater liquid and two of them for heated liquid. With special production, it is possible to produce heat exchangers which have more than one heater or heated liquids.
What is the difference between MIT plate and Standart plate heat exchangers?
In standart plate heat exchangers, there are 4 in-out ports and two of them are for heater liquid and two of them for heated liquid. With special production, it is possible to produce heat exchangers which have more than one heater or heated liquids. In MIT Plate Heat Exchangers, the flow is always diagonal.
