Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Embodiment one:
as shown in fig. 1-6:
a flying wing type fin comprises a radiating baseplate 1 and a flying wing type fin body 2, wherein the radiating baseplate 1 and the flying wing type fin body 2 are integrally formed, the flying wing type fin body 2 is corrugated, the flying wing type fin body 2 comprises a first fin 21 and a second fin 22, the first fin 21 and the second fin 22 are staggered to form a continuous wide space 8 and a narrow space 9, the top end of the second fin 22 is positioned at the narrow space 9 at the uppermost side, the bottom end of the first fin 21 is positioned at the narrow space 9 at the lowermost side, the upper side and the lower side of the radiating baseplate 1 are respectively provided with the first fin 21 and the second fin 22, the lengths of the first fin 21 and the second fin 22 at each side of the radiating baseplate 1 are different, the structure is a part of heat exchange, and the structure can be used as a part in any heat exchange device with a radiating fin structure, including but not limited to an air cooler and a wet cooling tower filler, the traditional heat exchange is generally carried out through a device with a radiating fin structure, on one hand, the traditional fins and the tubes inevitably have contact thermal resistance, so that the heat exchange efficiency is not high, on the other hand, the traditional fins basically only have the function of carrying out heat exchange with air, more dust is attached during use, the effect of heat exchange is influenced, the packing layer of the wet cooling tower is a key part of the wet cooling tower air cooler, a large amount of surface area is provided for increasing the contact area between water and air, a plurality of small holes or honeycomb structures are provided, the cooling efficiency of the wet cooling tower can be increased, the design is basically similar to that of the fins, the heat exchange is realized by increasing the contact area between the water and the air through the fins, the packing layer is the contact area between the water and the air, therefore, the combination of the two has certain advantages;
the flying wing type fin body 2 is made of elastic vibration material, for example, the material can be beryllium bronze, titanium bronze and copper-nickel-silicon-aluminum alloy, the beryllium bronze is tin-free bronze taking beryllium as a main alloy component, contains 1.7-2.5% of beryllium and a small amount of nickel, chromium, titanium and other elements, after quenching and aging treatment, the strength limit can reach 1250-1500 MPa, the level of the intermediate strength steel is approximate, the plasticity is good in a quenching state, various semi-finished products can be processed, the beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance, and also has good corrosion resistance, thermal conductivity and electrical conductivity; titanium bronze is an alloy appearing at the end of fifty years, and has the advantages of high strength (tensile strength of about 735-1373 MPa), hardness (hardness of about 250-400 HV), elasticity (Young's modulus of about 122.58E/GPa, elongation of about 8.0%) and good wear resistance, corrosion resistance, workability and weldability, as well as simple production process, abundant raw materials, low price and the like, which are the same as beryllium bronze; the copper-nickel-silicon-aluminum alloy has good elasticity, good conductivity, higher tensile strength, elastic limit and toughness, higher softening temperature, strong stress relaxation resistance, good processability, good welding and electroplating performances, high corrosion resistance and oxidation resistance, and rich and nontoxic raw materials.
According to the design of the scheme, heat exchange can be realized by increasing the heat radiating area, the air-cooling fin can be used as a filler in a cooling tower, the contact area between water and air can be increased, when the air-cooling fin is used as a radiator, the air flow speed is fixed when the air enters between the first fin 21 and the second fin 22, then when the air enters into the narrow space 9 after entering into the wide space 8, the air flow speed is increased, so that the air flow distribution is uneven when the air-cooling fin is in heat exchange with the first fin 21 and the second fin 22, the air flow distribution is greatly improved, the air flow distribution is uneven, and when the air flow distribution is uneven, the air-cooling fin body is enabled to enable dust to be more easily blown onto the surface of the air-cooling fin 2 by the wing body, and dust can be easily blown onto the surface of the air-cooling fin 2 by staggering the first fin 21 and the second fin 22;
it should be noted that, when the top end of the second fin 22 is located at the uppermost narrow portion space 9 and the bottom end of the first fin 21 is located at the lowermost narrow portion space 9, the ends of the first fin 21 and the second fin 22 can obtain better vibration, firstly, the corrugated arrangement of the first fin 21 and the second fin 22 gradually narrows toward the end, so that the airflow between the first fin 21 and the second fin 22 is unstable, the instability can cause vibration of the first fin 21 and the second fin 22, secondly, the extension lines of the ends of the first fin 21 and the second fin 22 point to each other, as shown in fig. 3, when the airflow flows out from the top of the first fin 21 and the second fin 22, the airflow is deflected upward to the right by the guiding action of the first fin 21, and the second tip 221 of the second fin 22 is deflected to the left, so that the airflow can be more violently impacted on the second tip 221; as shown in fig. 1, the same principle is adopted, and the first tips 211 on the lower side of the first fins 21 are also subjected to strong impact by the air flow.
By locating the tips of the second fins 22 at the uppermost narrow space 9, the bottom ends of the first fins 21 are located at the lowermost narrow space 9, and the tips of the first fins 21 and the second fins 22 are not in contact with any solid, so that better vibration of the tips of the first fins 21 and the second fins 22 can be achieved, since the tips of the second fins 22 are located at the uppermost narrow space 9, impact with the tips of the second fins 22 occurs when air accelerates through the narrow space 9, so that microscopic reciprocating vibration of the tips of the second fins 22 can be achieved, and the vibration frequency at the time of reciprocating vibration is related to the following parameters and factors:
1. modulus of elasticity of the material: the modulus of elasticity is a measure of the stiffness of a material that describes the ability of the material to deform under force, the higher the modulus of elasticity, the higher the vibration frequency of the material.
2. Density of material: the density of a material refers to the mass per unit volume, the higher the density, the lower the vibration frequency of the material.
3. Length of material: refers to the length of the part involved in vibration, and the longer the rod, the lower the vibration frequency.
4. Cross-sectional area of material: the cross-sectional area of the rod describes the thickness of the rod, the greater the cross-sectional area, the lower the vibration frequency of the rod;
it can be seen that, when the flying wing type fin body 2 is required to obtain a higher frequency, the thickness of the flying wing type fin body 2 needs to be reduced, in order to better trigger the vibration of the flying wing type fin body 2, the middle of the first fin 21 and the second fin 22 can be set to be thick, so that the flying wing type fin body 2 has good stability, the thicknesses of the first fin 21 and the second fin 22 towards two ends are gradually narrowed, the tail ends of the first fin 21 and the second fin 22 can be better triggered to vibrate, the top end of the second fin 22 is located at the uppermost narrow part space 9, the bottom end of the first fin 21 is located at the lowermost narrow part space 9, and therefore, the top end of the second fin 22 and the bottom end of the first fin 21 can be impacted by the part with increased airflow speed, and a better vibration effect is required, and the fact that only the tail end positions of the first fin 21 and the second fin 22 need to vibrate, and the whole vibration of the first fin 21 and the second fin 22 need not be performed is required to be described;
when the scheme is used as a filler in a wet cooling tower, the flying wing type fin body 2 vibrating at the tail end can better scatter large water drops, so that the contact area of water and air is increased, and further, better cooling of the water is realized, as the flying wing type fin body 2 is in corrugated arrangement, the large water drops can be necessarily contacted with the surfaces of the flying wing type fin bodies 2 when falling freely, cannot directly pass through a gap between the two flying wing type fin bodies 2, so that the water flows against the surfaces of the flying wing type fin bodies 2, the water has a larger contact area with the air, the flying wing type fin bodies 2 and the radiating substrate 1 can be arranged in an annular shape, a certain interval is arranged up and down, and the radiating substrate 1 and the flying wing type fin bodies 2 can be arranged in different diameter structures to be sleeved with each other, so that a better coverage area is obtained.
Further, the method comprises the steps of;
in an alternative embodiment, the first fin 21 and the second fin 22 are thick in the middle and gradually narrow in thickness toward both ends, and the narrower the vibration frequency is, the higher the vibration is triggered easily.
In an alternative embodiment, the lengths of the first fin 21 and the second fin 22 are different in the same direction.
In an alternative embodiment, the flying wing type fin body 2 is made of a material capable of elastically vibrating.
In an alternative embodiment, the heat dissipation substrate 1 and the flying wing type fin body 2 are made of materials with heat conductivity coefficient not less than 237.
In an alternative embodiment, the length of each of the first fins 21 and the second fins 22 is greater than the width of the heat dissipating substrate 1.
In an alternative embodiment, the heat dissipation substrate 1 is a tubular structure, and when used as a heat dissipation device for liquid in a pipeline, such as an evaporator, as shown in fig. 4, the heat dissipation substrate 1 is configured as a square tube, so that the liquid can flow inside the heat dissipation substrate 1.
In an alternative embodiment, the extension lines of the ends of the adjacent first fins 21 and second fins 22 are directed to each other to form a group, and the groups of the first fins 21 and the second fins 22 are arranged in equal interval succession.
In an alternative embodiment, the method of manufacturing the flying wing type fin body 2 includes the steps of:
s1: firstly, processing two side surfaces of a radiating substrate 1 into an flying wing type fin body 2 with gradually narrowed free ends in a shoveling processing mode;
s2: bending the flying wing type fin body 2 into a corrugated shape;
s3: cutting off the redundant upper excess material part 3 to form an intermediate part 23 of the flying wing type fin body 2;
s4: the excess first side remainder 4 and the second side remainder 5 are cut off.
In this embodiment: since the flying wing type fin body 2 is processed by a shoveling process, in order to eliminate contact thermal resistance, the flying wing type fin body 2 with gradually narrowed free ends is processed by the shoveling process on two side surfaces of the radiating base plate 1, the flying wing type fin body 2 is bent into a corrugated shape by an extrusion process, although the flying wing type fin body 2 has vibration elasticity, engineering materials and components are permanently deformed after being loaded beyond an elastic deformation range, then redundant upper residual material parts 3 are cut off by a cutting process to form a middle part 23 of the flying wing type fin body 2, the bending shape of the middle part 23 of the flying wing type fin body 2 is the same as the bending curvature of side parts 24, and finally redundant first side residual material parts 4 and second side residual material parts 5 are cut off, and only the radiating base plate 1 and the flying wing type fin body 2 are left.
