How to choose the right type of heat exchanger for your application?It always be a big problem for anybody who don’t understand the theory of heat exchangers. So, before you make the decision, you should find out this question : What is a heat exchanger ? As its name suggests, a heat exchanger is a tool that enables efficient temperature exchange between two materials , which are at different temperatures , within the heat exchanger. One side is called a heat source and the other is called a cold source. Different types of Heat exchangers: The exchange of temperature between different substances requires different types of heat exchangers. On the market , common types of heat exchanger are Shell-and-tube heat exchanger, heat exchanger with tank, immersed heat exchanger, box heat exchanger, plate heat exchanger. Shell-and-tube heat exchanger according to the arrangement of its tubes, can be divided into: coil heat exchanger, tube-in-line heat exchanger. Different heat exchanger for different Applications / Conditions : But under what conditions and what types of heat exchangers are suitable What factors should be considered in the selection of heat exchangers Let’s take a look at the scenarios we don’t use. 1. Fish tank refrigeration-titanium coil heat exchanger: fish are very sensitive to changes in water environment, especially water cleanliness and water temperature. In particular, the use of chillers/thermostats to control water temperature is very necessary for the cultivation of seafood and fish. For the small seafood pool thermostat, we generally choose titanium coil shell-and-tube heat exchanger, or directly use titanium immersion tube heat exchanger. Titanium has a good corrosion resistance, so in the sea water treatment applications are quite outstanding, but also very common, the normal service life of up to 5 years. If the use of copper or stainless steel pipe made of
