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
Advantages
Light weight(fin+tube=inner passages)
High efficient
Lower manufacturing cost
Disadvantages
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
Advantages
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\
Disadvantages
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
Thirdly-tank
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.
