How does a plate heat exchanger work?

The plate heat exchanger is just one method of transferring heat between two fluids, and are especially useful for heat transfer between two liquids. Examine the plate heat exchanger shown in Figure 1.

Why are the gaskets on a heat exchanger marked?

Because the gaskets guide flow through the heat exchanger, it is essential they be installed in the correct order. For this reason, gaskets are often fitted with markings so that operators can check each plate is installed in the correct order throughout the entire plate stack.

How does the hot medium enter the heat exchanger?

The hot medium enters the heat exchanger through the hot medium inlet. Gaskets direct the hot medium as it flows through the heat exchanger. Each plate has an alternating gasket pattern. The hot medium flows into the space between a pair of plates, but does not flow into the space between the next pair of plates because the gaskets prevent this.

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 principle of plate heat exchanger?

A heat exchanger follows the equalisation principle. 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. Heat is always transferred from a hot medium to a cold medium.

How does the hot medium enter the heat exchanger?

The hot medium enters the heat exchanger through the hot medium inlet. Gaskets direct the hot medium as it flows through the heat exchanger. Each plate has an alternating gasket pattern. The hot medium flows into the space between a pair of plates, but does not flow into the space between the next pair of plates because the gaskets prevent this.

Where do the bolts go on a heat exchanger?

The tightening bolts fit in some grooves on the side of the unit and they’ll run the entire length of the heat exchanger. The bolts tighten onto these bars and compress all of the plates and gaskets together forming a water tight seal. Wedged between the end plates are the gaskets and heat transfer plates.

What is the flow pattern of a heat exchanger?

The flowing mediums thus have a hot, cold, hot, cold, flow pattern, as they flow through the heat exchanger. Both flowing mediums are completely separated from each other by the gaskets and plates, they do not mix. Due to the close proximity of the flowing mediums, heat is exchanged between them.
