Description
Technical Field
The utility model belongs to the technical field of radiating fin, especially, relate to a fin is used in air conditioning system heat transfer.
Background
In an air conditioning system, heat dissipation fins with heat dissipation pipe holes are installed outside a heat dissipation pipeline, the heat dissipation fins are generally made of materials such as aluminum plates with good heat conduction, and adjacent heat dissipation fins form an air channel and exchange heat with air through the fins. The early heat exchange fins are flat plates, so that when air passes through an air channel formed between adjacent heat exchange fins, the air temperature at the contact positions of the two sides of the air channel and the heat exchange fins is higher, while the air temperature at the middle part of the air channel is lower, which is not beneficial to heat exchange.
In order to solve the problems, the air windows are arranged at the positions, away from the radiating pipe holes, of the heat exchange fins, and in the air flowing process, the air windows block air, so that certain resistance exists in the air flowing process, and the air can also cause the mixing of cold air and hot air due to the blocking of the air windows, so that the heat exchange effect is further improved. However, due to the structure of the existing windshield, the existing radiating fins have the following defects: firstly, dust or impurities in the air are hung on the air window while the air window blocks the air, and the heat conductivity of the dust and the impurities is small, so that the heat exchange of the fins is influenced; secondly, the dust or sundries block the air duct, so that air cannot pass through the air duct, the heat dissipation effect is seriously affected, and the air duct needs to be cleaned regularly.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a fin for air conditioning system heat transfer that simple structure, heat transfer are effectual, be convenient for maintain.
In order to solve the above problem, the utility model relates to a technical scheme that fin adopts for air conditioning system heat transfer is: the fin comprises a fin body with a radiating pipe hole, wherein a plurality of curved surface bulges are arranged on the side surface of the fin body of the radiating pipe hole at intervals.
The additional technical characteristics are as follows:
the other side of the fin body corresponding to the curved surface bulge is a curved surface groove;
the curved surface bulge is in a spherical crown shape;
the ratio of the height to the width of the curved surface protrusion is 1: 5;
and an electric heating wire is arranged at the curved surface bulge on the fin body positioned at the lowest part.
The utility model provides a fin for air conditioning system heat transfer compares with prior art, has following advantage: firstly, the radiating pipe penetrates through the radiating pipe hole, the surface area of the fin is increased due to the plurality of curved surface bulges, the strength is enhanced, the surface of the fin is smooth, dust and impurities are not easy to hang, the radiating capacity is enhanced, when air circulates in the air channel, the air is collided with the curved surface bulges to cause mixing of cold air and hot air, and the heat exchange effect is better; secondly, because the other side of the fin body corresponding to the curved surface bulge is a curved surface groove, and the curved surface bulge and the curved surface groove are formed by stamping the fin body, the processing is convenient, and the combination of the curved surface bulge, the curved surface groove and the periphery is a smooth surface, so that dust and sundries are not easy to deposit; thirdly, because the curved surface bulge is in the shape of a spherical crown, the processing is convenient, the wind resistance is small, the air circulation is convenient, and the heat exchange efficiency is improved; fourthly, because the ratio of the height to the width of the curved surface bulge is 1:5, the heat exchange area is effectively increased, the wind resistance is low, and the air circulation is convenient; fifthly, because be located the below the curved surface protruding department on the fin body is provided with electric heating wire, when the temperature was lower winter, give the heating of fin body through electric heating wire, avoided the vapor in the air fin for the heat transfer to freeze, heat in the fin below in addition, passageway about forming between adjacent fin, the air density after the heating diminishes and rises along the passageway between the adjacent fin for all be difficult to freeze on the whole fin, it is more convenient to use.
Drawings
FIG. 1 is a schematic structural view of a heat exchange fin of an air conditioning system according to the present invention;
fig. 2 is a plan view of a heat exchanging fin for an air conditioning system.
Detailed Description
The structure and the using principle of the fin for heat exchange of the air conditioning system of the present invention will be further described in detail with reference to the accompanying drawings and the specific embodiments.
As shown in fig. 1 and fig. 2, the utility model relates to a structural schematic diagram of fin for air conditioning system heat transfer, the utility model relates to a fin for air conditioning system heat transfer is provided with a plurality of curved surface archs 3 including the fin body 2 that has heat dissipation tube hole 1 at the 2 side intervals of fin body of heat dissipation tube hole 1.
The cooling tube passes the radiating tube hole, and a plurality of curved surface archs 3 make the surface area increase of fin, and intensity reinforcing, fin surface are smooth, and dust and debris are difficult to be hung, and the heat-sinking capability reinforcing, when the air circulates in the wind channel, the air leads to the fact cold and hot air to mix through colliding with curved surface archs 3, and the heat transfer effect is better. And the curved surface protrusion 3 can also increase the strength of the fin body 2.
The other side of the fin body corresponding to the curved surface protrusion 3 is a curved surface groove 4, the curved surface protrusion 3 and the curved surface groove 4 are formed by stamping the fin body, the processing is convenient, and the smooth surfaces at the joint of the curved surface protrusion, the curved surface groove and the periphery are not easy to cause dust and sundry deposition.
The curved surface bulge 3 is in a spherical crown shape, so that the processing is convenient, the wind resistance is small, the air circulation is convenient, and the heat exchange efficiency is improved.
The ratio of the height to the width of the curved surface protrusions 3 is 1:5, so that the heat exchange area is effectively increased, the wind resistance is low, and the air circulation is facilitated.
The electric heating wire 5 is arranged at the curved surface bulge 3 on the fin body 2 located at the lowest position, when the temperature is lower in winter, the fin body 2 is heated through the electric heating wire 5, the phenomenon that water vapor in the air freezes on the fins for heat exchange is avoided, an upper channel and a lower channel are formed between adjacent fins when the water vapor is heated below the fins, the air density after heating is reduced, and the air density rises along the channels between the adjacent fins, so that the whole fins are not easy to freeze, and the use is more convenient.
