What is a heat exchanger?

A micro-channels plates for Heat exchanger is a device in which heat exchanges between the substance to heat and the carrier of heat or cold.

What does a heat exchanger do?

In a heat exchanger, also called a heat exchanger. Heat transfers and the two elements do not come into direct contact with each other, but guide past each other. This works with both liquid and gaseous substances. In order to work efficiently, heat exchangers require a large area.

With this technology, for example, condensing boilers can achieve a very high level of efficiency. The warm exhaust gases from the thermal bath of micro-channels plates for Heat exchanger use here to heat a heat-storing container. The pipe with return-flowing heating water runs through this tank.

The water has already heated before it reaches the thermal baths. This saves energy – and therefore costs.

Heat exchangers also use in heat pumps and solar systems. Ventilation systems use heat exchangers to recover heat from the exhaust air, for example in passive houses.

  • Substance to be heated: water, oil, chemicals, products (liquids)… in general
  • Heating agent: steam, heating oil, hot water.

Types of micro-channels plates for Heat exchanger

Direct heat exchanger:

  • Boiler feed water heating
  • Heating water tanks, intermediate liquids in the production process

Indirect heat exchanger:

Heat exchangers for heating: function and use

Heat exchangers are technical devices that transfer thermal energy from one substance to another. Irrespective of the respective state of aggregation (gaseous or liquid), the two media do not come into contact with one another. The micro-channels plates for Heat exchanger are part of every heating system and requires to heat water or air.

Structure and function of the heat exchanger

The task of a heat exchanger is to transfer thermal energy (heat) from one substance to another. This works quite simply with a pipe that conducts warm heating water through a drinking water storage tank. The heating water emits heat while its temperature drops.

At the same time, the drinking water absorbs thermal energy. It warms up and can then consume in the house.

How well the micro-channels plates for Heat exchanger works depends, among other things, on the material of the components. Metals that conduct well, such as copper, aluminum or stainless steel, are favorable. The heat exchanger surface (in the example the surface of the pipe) is also relevant. The larger this is, the more heat can transfer in the same time.

The direction of flow of the various media also has a major influence on the performance of the heat exchanger. The devices work best when heat donors and heat receivers flow past each other in opposite directions. Experts speak of counter flow heat exchangers.

In addition to these, there are also cross and direct current heat exchangers, which transfer less heat with otherwise the same parameters.

Different types of micro-channels plates for Heat exchanger

Depending on the structure of the heat exchanger, experts distinguish between different types of devices. In addition to the coiled-tube heat exchangers already described, heating technology mainly plate heat exchangers use.

These consist of numerous plates arranged one on top of the other, between which there are shallow channels. During operation, heat donors and heat receivers each flow through adjacent channels, with thermal energy transfer from the warmer to the cooler substance.

The heat exchangers are compact, efficient and available in a wide variety of performance ranges.

Air-to-water micro-channels plates for Heat exchanger are also used to extract heat from the air or to heat the air. Outside or room air flows through fine, water-carrying pipes (heating or cooling coils). When heating, these are flown through by hot heating water, which gives off heat to the passing air.

When cooling, cold water flows through the heat exchanger surfaces. The medium extracts energy from the air, causing its temperature to drop.

Selection and dimensioning for high efficiency

So that heat exchanger fulfills their task, they have to be suitable for the desired place of use. In addition to the right type, the right size of the heat transfer surfaces is also important.

The following applies: The more the micro-channels plates for Heat exchanger have to perform, the larger the transmission area must select. It is also important that materials and designs are suitable for the media used, their chemical composition and temperatures.

Applications of modern heat exchangers

Heat exchangers are used in a wide variety of areas. For example, they transfer the heat from a boiler to the heating water. They sit as so-called water pockets in chimneys or transfer thermal energy to a solar system on the heating water.

It is also typically used in water heaters or fresh water stations, in which heat exchangers transfer thermal energy from the heating water to the drinking water.

The components also help to reduce heating costs in modern micro-channels plates for Heat exchanger. Here they guide the combustion gases past the cold return water. The heating water absorbs energy that would otherwise disappear unused up the chimney.

The heat exchanger is also called "heat exchanger" in technical jargon. With its help, energy can transfer from one material to another (in technical jargon this is called "recuperation"). The special thing about this is that the bodies do not come into contact with each other. In this case, the heat transfers through a liquid or a gas.

Heat exchangers in heating technology

Indirect heat transfer is used in radiators, since the material flows separate by a heat-permeable wall (the material of the radiator). Micro-channels plates for Heat exchanger are used, for example, in households to heat service water or water for heating.

A gas boiler heats water with a gas flame. The thermal energy of the flame transfers to the water flowing through a heat exchanger. Heated and driven by the heating boiler, the water flows through the pipe system of the heating system and forms a circuit.

It runs via the so-called water inlet into the radiator, further via the water return and finally back into the thermal bath, where it heats up again.
