What is Heat Exchanger – Galaxy Process?


Heat exchangers are a staple in today's devices. They did not exist except in the simplest devices. They also found use in large-scale industries and services in the world today. They are basically devices in some machinery and equipment which enables it to heat transfer from one medium to another. They facilitate heat transfer efficiency from one object to another.

The use of heat exchangers:
One example of this is radioactive in cars or air conditioners. What usually happens is that the heat source is transferred water that will cool the engine through the exchanges. Exchangers transfer the heat from the water to the air, leaving the engine cooler.

It is widely used for heating purposes of air conditioning and refrigeration so. Heavy industries that also use this technology include electric power generation, chemical and petrochemical plants, oil refineries and petrol stations, natural gas processors, sanitation and water treatment.

Types of flow Heat exchangers:
It can be classified into two types, mainly according to their flow arrangement. This is a parallel flow heat exchanger counter-flow.
Exchanger of parallel flow involves two means going in the exchanges during the same side of the device. For example, two fluids enter the exchanger on the same side and travel parallel to each other on the whole process.
Counter flow heat exchanger, on the other hand, it is the opposite of the first operation. Here, the fluid will enter the device from different ends meet each other and to the process of heat exchange. Many of these use this flow because it is proven to be more effective than the two operations because it can transfer more heat from the heating medium to another. In this setting, the means to travel to each other and then are processed by a heat exchanger.

Traditionally, it has been exchanger is designed in a way that is maximized space between two fluid exchanger while minimizing resistance to the flow of trade at the same time. Additional fins installed in either direction, where the intervention fluids can also strengthen these exchanges. These fins in addition to the surface area of ​​the exchangers while also helping to control the flow of fluids during the exchange process.

The temperature during the heat exchange process:
Depending on the size of the exchanger and the temperature varies during the exchange process. The temperature also varies according to the position of the machine. But many of the industries in which the Heat Exchanger Manufacturer in India is almost always used their own definition of average temperatures.
This heat is usually defined in terms of the difference in the temperature record average or LMTD. Although sometimes the temperature is still difficult to determine through LMTD method, in this case, it is then used method of National Taiwan University.

Types of Heat Exchanger:
There are several types of heat exchangers used today. These exchanges include the shell tube, and plate heat exchangers, adiabatic wheel, plate fin, and exchanges fluid, dynamic scraped surface, and exchanges phase change, coil air HVAC, and exchanges spiral exchangers direct connection.
