Which parameters of laser welding stainless steel finned tube have influence on heat dissipation?

-
What are the effects of some parameters in the finned tube on the heat dissipation? The following laser welded composite fin tube small braid will be analyzed and explained by Murphy experts , so that you can clearly understand.
1. Contact thermal resistance
If the contact thermal resistance is not good, the effect on heat dissipation will be more than 20%.
2. Fin tube height
If the height of the fins is increased, the heat dissipation area will be increased, thus increasing the heat dissipation. However, this can not be increased blindly, but also consider the rationality of size.

3.Fin tube spacing
If the fin spacing becomes smaller, the heat dissipation will be increased, but the smaller the fin spacing is, the better. If the fin spacing is too small, it will bring adverse effects. Therefore, it is generally quiet, with two tubes of 3-4mm, four tubes of 4-5mm and six tubes of 5-6mm.
4. Fin diameter
If the diameter of the fin increases, the heat dissipation will increase, but there are some disadvantages. If the fin height is relatively small and the fin distance is relatively small, then the pipe diameter should also consider the rationality.
5. Number of fin tubes
Increasing the number of fins can also improve the heat dissipation, but it will increase the cost and so on. Therefore, it is not very economical to consider from the economic aspect.

Everything you should know about U bend tube

  Murphy can make  U bend tube  in our factory according to customer requirements. The elbow is heat treated according to the customer’s requirements, and then hydrostatic pressure test and dye penetration test are performed as needed. U-shaped elbows are widely used in  heat exchanger  systems. Heat exchanger equipment based on stainless steel U bend tube plays an important role in the nuclear industry and petrochemical machinery manufacturing. U bend tube heat exchangers are specially designed for high temperature applications, especially steam condensing or hot oil systems. When the differential expansion makes the fixed tube-sheet heat exchanger unsuitable, and in some cases the floating head type (HPF) cannot be selected, the U bend tube heat exchanger will be selected. The surface of the finished U-shaped elbow should be free from scale and scratches after bending. Dimensional tolerance U-bend pipes are in accordance with relevant regulations of TEMA R.C.B. and ASTM A566 and ASTM

1. Metal material heat exchanger Common materials are carbon steel, alloy steel, copper and copper alloy, aluminum and aluminum alloy, titanium and titanium alloy. Because the thermal conductivity of metal material is large, the heat transfer efficiency of this kind of heat exchanger is high. 2. Non-metallic material heat exchanger Commonly used materials are graphite, glass, plastic, ceramics, etc. Because of the small thermal conductivity of nonmetallic materials, the heat transfer efficiency of this type of heat exchanger is low. Often used in corrosive systems. hashtag www.murphyfinnedtubes.com 1. Tube heat exchanger A heat exchanger that conducts heat through a tube wall. It can be divided into shell heat exchanger, coil heat exchanger, tube heat exchanger, fin heat exchanger and so on. 2. Plate heat exchanger A heat exchanger that conducts heat through a plate surface. According to the structural form of heat transfer plate can be divided into plate type, spiral plate

Spiral plate heat exchanger equipment quality problems.

Spiral plate heat exchanger equipment can be broken down, mostly because of quality problems. Compared with the heat transfer surface of other heat exchangers, the heat transfer surface of this heat exchanger is quite thin, that is, 0.5mm, and the allowable high corrosion degree is 0.05mm/ year. The material of common spiral plate heat exchanger equipment usually USES alloy material (304 or 316), 304 is the low cost of austenitic stainless steel, has the ability to resist corrosion to a certain range of organic matter, but the ability to resist hydrochloric acid and sulfuric acid is weak. Spiral plate heat exchanger equipment can be broken down, but also because of its own maintenance problems. Spiral plate heat exchanger equipment is an important component of heat exchange technology in process industrial equipment. The resilient gasket that seals between the various helical fins is a vulnerable part and also an easily aged part under natural conditions. Its service life has an impo
