Titanium Stainless Steel Shell And Tube Heat Exchanger
Titanium Stainless Steel Shell And Tube Heat Exchanger is the equipment that can transfer certain heat from the thermal
fluid to the cold fluid. It is the essential equipment to achieve
the heat exchange and transfer during the production process.
Tube heat exchanger is a high-efficiency heat exchanger suitable
for steam-steam, steam-liquid and liquid-liquid heat transfer.
Coolant dry evaporator
Cooling air dry evaporator (direct evaporative air cooler)
1. Dry tube shell falling film evaporator
Shell-and-tube dry evaporators are divided into straight tube type
and U-shaped tube type. Their common feature is that there are
multiple rounded baffles in the shell, the purpose is to increase
the flow of refrigerant outside the tube and enhance the heat
exchange effect.
The characteristics of the dry shell and tube falling film
evaporator are:
① It can ensure that the lubricating oil entering the refrigeration
system returns to the compressor smoothly;
② The required refrigerant charge is small, only 1/3 of the same
capacity flooded evaporator;
③ When used for cooling water, even if the evaporation temperature
reaches 0℃, there will be no icing accident;
④ The thermal expansion valve can be used for liquid supply, which
is more reliable than the liquid-filled float valve.
Shell-and-tube heat exchangers are also known as tube-and-tube heat
exchangers. The partition wall heat exchanger is a heat transfer
surface which is closed on the wall surface of the tube bundle in
the casing. The heat exchanger has a simple structure and reliable
operation, can be manufactured by various structural materials
(mainly metal materials), can be used under high temperature and
high pressure, and is the most widely used type at present.OEM

The evaporator is the cold output device in the refrigerator. The
refrigerant evaporates in the evaporator and absorbs the heat of
the low-temperature heat source medium (water or air) to achieve
the purpose of refrigeration.
The evaporator is divided into different cooling media: the
evaporator used to cool the air, and the evaporator used to cool
the liquid (water or other liquid refrigerants).
