Where are liquid to liquid heat exchangers used?

They are commonly used for healthcare diagnostics & treatment as well as industrial applications. The system consists of a pump to circulate coolant, a liquid heat exchanger to dissipate heat, and a liquid circuit to transfer coolant from the heat source to the liquid cooling system.

What is a water to water heat exchanger?

Water to water heat exchangers transfer heat energy from one liquid to another without bringing the two liquids into direct contact in a similar method as air to air heat exchangers.

How does a liquid to liquid heat exchanger differ from a radiator?

Commonly, heat exchangers are thought of as liquid-to-liquid devices only. But a heat exchanger is any device that transfers heat from one fluid to another. Some equipment depend on air-to-liquid heat exchangers. From the radiator, the hot coolant flows into the tube side of the radiator (heat exchanger).

What is process fluid in heat exchanger?

On the liquid side of these heat exchangers, the common fluids are water, a water-glycol solution, steam, or a refrigerant. For heating coils, hot water and steam are the most common, and this heated fluid is supplied by boilers, for example. For cooling coils, chilled water and refrigerant are most common.

How are heat exchangers made?

Generally, they are built with a flat plate design or a shell and tube design. Air, liquids, or steam flow through a network of heat conducting tubes or cavities lined with heat conducting plates. Plate heat exchangers come in two basic configurations—flat plate heat exchangers or plate and frame heat exchangers.

What size water to water heat exchanger do I need?

Many customers ask, “how do you know what size plate exchanger to install in your domestic hot water tank?” A simple rule of thumb is 2 to 3 people in one house will determine a 10 plate. A 10 plate heat exchange is enough for 2 and 3 people.
