Shell and Pipe Heat Exchanger

Shell pipe heat exchanger

Shell and pipe heat exchanger is a kind of high efficiency heat exchanger which is composed of high efficiency Ω style inner pipes and shell that has baffle plate. It has the advantages of shell & tube heat exchanger and plate heat exchanger. The shell is made of plastic(PA6) liner, foam material and steel outer shell.

Shell and pipe heat exchanger-feature

① Anti-freezing

Heat exchanging inner core has a structure of Ω, baffle plate all have the ability of elasticity, so it can anti-freezing.

② Anti-corrosion, long serve life

All surface connect with the water is made by plastic, so it has a better ability of anticorrosion, and can serve for a long time. What’s more the passage of water is large, and not easy to get blocked.

③ High efficiency

Inner pipe is small diameter high efficiency internal thread, and it has a special Ω structure, it can increasing turbulence flow and heat exchanging. HZSS engineers have been simulating and optimization for many times, it is compact and has good performance of heat transfer.


④ Refrigerant outlet and inlet is specially sealed, no leakage

Sealing components can resistant temperature from 200℃ to -20℃,and sealing covers are used for fixing, which makes the sealing reliable.

⑤ Filling with heat insulation material, decline heat leakage

The steel shell and the engineering plastic inner bladder are filled with foaming materials, which effectively reduce the heat loss of the heat exchanger. The user does not need to add insulation for the shell.


    For shell and pipe heat exchanger’s excellent ability of heat transfer and adaptation, it is widely used for:
  1. 1. water chiller evaporator
  2. 2. swimming pool heat pump condenser/evaporator
  3. 3. mariculture constant temperature evaporator and condenser
  4. 4. salt solution dehumidifier condenser and evaporator
