Laser welded finned tube radiator is a very good energy-saving and environmental protection mechanical equipment, which can be used again in all aspects of mechanical energy that would have been wasted. Laser welded finned tube radiator is a member of the heat exchanger family. Today's website will explain some basic principles and characteristics of laser welded finned tube radiator, It has a better feeling and application for the laser welded fin tube radiator
Laser welded finned tube radiator is generally composed of clapboard, plate fin, sealing and drainage plate. A sandwich composed of plate fin type, drainage method sheet and seal is placed between two adjacent partitions, which is called emergency exit. The sandwich is stacked according to different ways of fluid dynamics, and the fiber is welded as a whole to form a plate bundle. The plate bundle is an important part of the laser welded finned tube radiator, plus the indispensable stainless steel head, connection and sealing Fulcrum and so on formed the laser welding fin tube radiator.
From the basic principle of heat conduction, the laser welded finned tube radiator is still a shoulder arm heat exchanger. Its main feature is that it has an extended secondary heat conduction surface (plate fin type), so the whole process of heat conduction can be carried out not only on the primary heat conduction surface (partition), but also on the secondary heat conduction surface. The calorific value of the chemicals on the high-temperature side is not only poured into the chemicals on the low-temperature side once, but also transferred along the height direction of the plate fin surface, that is, along the height direction of the plate fin type, there is a partition plate poured into the calorific value, and then this kind of calorific value is widely known to the chemicals on the low-temperature side.
Because the height of the plate fin is much higher than the thickness of the plate fin, the whole process of heat conduction along the height of the plate fin is similar to that of the uniform long thin guide rod. In this case, the thermal conductivity of plate fin type can not be ignored. The temperature of the two sides of the plate fin type is greater than that of the partition plate. With the convective heat release between the plate fin type and the chemical substance, the temperature decreases until the temperature of the chemical substance in the middle of the plate fin type.

1.The results show that the heat conduction efficiency is high, and the plate fin structure has a large heat conduction index due to the continuous cracking of the boundary layer due to the oscillation of fluid dynamics; In addition, because the baffle and plate fin type are too thin and have high thermal conductivity, the promotion of laser welding fin tube radiator can ensure high efficiency.
2.Compact because the laser welded fin tube radiator has extended secondary surface, the apparent density can be guaranteed to be 1000 m2 / m3.
3.The reason for its lightness is that it is compact and commonly used in the production and processing of aluminum profiles. Nowadays, steel, copper, fiber materials and so on have been produced in batches for a long time.
4.Strong adaptability,Laser welded finned tube radiators can be used: all kinds of heat conduction in the middle of fluid dynamics and phase change heat transfer which cause lumped state change. According to the reasonable layout and composition of the flow passage, different heat conduction conditions such as counter flow, cross flow, multi-core flow and multi-pass flow can be integrated. According to the control module connected, series, series parallel circuit composition can consider the heat conduction of large, medium and small mechanical equipment. In industrial production, it can be finalized and mass produced to control the cost and expand the exchangeability according to LEGO assembly structure.
5.The production process is demanding and the whole process is complex. It is easy to block, not resistant to corrosion, and difficult to remove and repair, so it is only used in clean, clean, anti-corrosion, not easy to scale, not easy to deposit and not easy to block sites of heat transfer chemicals.
The above is for you to explain the basic principles and characteristics of the laser welding fin tube radiator, hope to help you, in the future you buy laser welding fin tube radiator to save a lot of time.
