What's the difference between tube fin&bar plate heat exchanger ?

With the wider application of heat exchanger in various industries, more and more people or companies are using it, they will face the problem of structure of heat exchangers.

So...what's the difference between tube fin&bar plate heat exchanger ?

Firstly-construction type

1.Tube fin heat exchanger


  • Light weight(fin+tube=inner passages)

  • High efficient

  • Lower manufacturing cost


  • Radiator core is thinner than the thickness of tank, with less heat dissipation area than bar&plate.

  • High possibility of leakage, not suitable for High Vibration or heavy duty working condition

  • Long developing time

2.Bar plate heat exchanger


  • Compact structure (External Bar+ Inner Bar + Inner Fin )

  • High Performance and longer using life

  • Higher Pressure Capability

  • Endure High Vibration Working Condition

  • No need tube modeling cost , can be customized in various sizes\


  • Compared with tube fin radiator, the radiator weight becomes larger and the cost increase

Secondly-brazing way

1.Tube fin heat exchanger

  • The workpiece is driven by stainless steel mesh belt to finish the welding process

  • Transmission through the belt, after preheating, heating , welding, cooling down.

  • All the process is protected by hydrogen, to keep the product is bright and not oxidized.

  • The welding process is to melt the filling material (solder) by heating the work piece(1200°C), to fill the gap between the base metal by capillary action, and to achieve the purpose of welding after cooling

  • Can not keep the high pressure and high temperature as long as the Vacuum Brazing Furnace

2.Bar plate heat exchanger

  • Vacuum Operating Working Condition

  • Maximum operating temperature 2400°C

  • The stepless optimization adjustment of heating original is carried out by SCR controller;

  • Extreme vacuum pressure can reach to x 1 x 10-7 mbar 

  • Automatic control of heat treatment process;

  • Temperature uniformity ±5℃ in effective space

  • Better energy saving and thermal performance, less than 1 x 10-4 leakage rate


1.Tube fin heat exchanger- could be assembled with plastic & aluminum tanks

As the default of weak capability against the high Cylinder shock and thermal shock, the tube fin heat exchangers mainly Used For auto Cooling, OEM vehicle manufacturers and after market usage.

2.Bar plate heat exchanger- only with aluminum tanks

More widely used than tube fin heat exchangers, especially for heavy duty and high pressure industry working application, like Railway, Electronic, Hydraulic & Lubricant System, Compressed Air & Gas, New Generation, Automotive and Various Industry Applications.
