How does a plate heat exchanger work?

How does a plate heat exchanger work?

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 are the types of plate heat exchanger?

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.

What are the 5 different types of heat exchangers?

Types of Heat Exchangers

  • Shell and tube heat exchangers.
  • Double pipe heat exchangers.
  • Plate heat exchangers.
  • Condensers, evaporators, and boilers.

Where is plate type heat exchanger used?

You’ll find gasket plate heat exchangers used in many HVAC applications to indirectly connect chillers, boilers and cooling towers to central plant systems. They’re also used for economiser circuits and heat recovery circuits to reduce the cooling load on the chillers.

Which is not a plate type heat exchanger?

Which of the following is not a Plate – Type heat exchanger? Explanation: Plate type heat exchangers can be classified as Gasketed, brazed and Welded (full or semi). Other categories are plate coils, spiral plate, etc. 3.

What is the main advantage of plate heat exchangers?

Efficiency – One of the biggest advantages of plate exchangers is the efficiency that accompanies their compact design. These heat exchangers are created with several corrugated plates on the frame of the equipment, essentially creating a design that uses the entire body during the heat transferring process.

How long does a plate heat exchanger last?

A typical heat exchanger should last for around 10 years in full working order.

What are the disadvantages of a plate type heat exchanger?


  • Initial cost is high since Titanium plates are expensive.
  • Finding leakage is difficult since pressure test is not as ease as tube coolers.
  • Bonding material between plates limits operating temperature of the cooler.
  • Pressure drop caused by plate cooler is higher than tube cooler.
