[ detailed description ] of the utility model
In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1 to 4, a stainless steel heat exchange tube comprises a tube body 1, wherein a pattern part 2 is arranged on the inner side of the tube body 1, the pattern part 2 comprises a plurality of diamond-shaped bulges 21, the diamond-shaped bulges 21 are arranged at intervals and uniformly distributed on the inner wall of the tube body 1, and the diamond-shaped bulges 21 are staggered up and down so as to form a net-shaped heat dissipation groove 22 for heat exchange on the inner wall of the tube body 1.
In this embodiment, the inner wall of the pipe body 1 is provided with the pattern part 2, wherein the pattern part 2 is formed by arranging a plurality of diamond-shaped protrusions 21, since the diamond-shaped protrusions 21 are arranged at intervals, the gaps between the diamond-shaped protrusions 21 are mutually communicated to form the heat dissipation grooves 22 for heat exchange, and when water flows through the heat dissipation grooves 22, since the diamond-shaped protrusions 21 are uniformly distributed in the inner wall of the pipe body 1, that is, the side surfaces of a plurality of diamond-shaped protrusions 21 are increased at the same time, the contact area for heat exchange is increased, and the heat exchange efficiency of the pipe body and the water flow is improved, that is, the heat dissipation efficiency of the pipe body is improved.
Preferably, the plurality of diamond-shaped protrusions 21 in the pattern part 2 are arranged, so that a series of regularly and closely arranged heat dissipation grooves 22 are formed on the inner wall of the pipe body 1, and the heat dissipation grooves can increase the contact area between water flow and the inner wall of the pipe body during heat exchange, thereby improving the heat transfer efficiency, and the layout and design of the diamond-shaped protrusions 21 in the pattern part 2 are beneficial to reducing the resistance loss of water flow while increasing the contact area. The interval arrangement and the regular arrangement between the diamond-shaped bulges 21 enable the water flow to flow on the inner wall of the pipe body more smoothly, and reduce the energy loss caused by resistance loss.
Further, the diamond-shaped protrusions 21 on the same plane are sequentially arranged along the circumferential direction of the pipe body 1 to form an annular layer 23, and the annular layer 23 is provided with a plurality of diamond-shaped protrusions, and the diamond-shaped protrusions are sequentially arranged along the axial direction of the pipe body 1 to form the pattern portion 2.
In this embodiment, by the arrangement of the annular layer 23, the plurality of diamond-shaped protrusions 21 on the same plane are arranged along the circumferential direction of the pipe body, and the plurality of diamond-shaped protrusions 21 on the same plane are arranged along the circumferential direction of the pipe body 1, so that heat is uniformly distributed on the inner wall of the pipe body 1; this uniform heat distribution helps to avoid heat accumulation and localized overheating phenomena, maintaining the stability of the overall heat dissipation effect.
Further, in the two adjacent annular layers 23, an a layer and a b layer are respectively provided, and the diamond-shaped protrusions 21 of the a layer and the diamond-shaped protrusions 21 of the b layer are staggered.
In this embodiment, the staggered arrangement is on the one hand such that the diamond-shaped protrusions of the a-layer and the diamond-shaped protrusions of the b-layer form a more complex texture when water flows through. The complex texture increases the contact area between the inner wall of the pipe body and the water flow, further improves the heat exchange efficiency, and on the other hand, the heat in the pipe body is more uniformly distributed on different layers. In this way, heat can be more efficiently transferred from the a-layer to the b-layer and then dissipated to the outside environment. The layered transmission and heat dissipation mode is beneficial to avoiding heat accumulation and overheating on a certain layer, the overall heat dissipation performance is improved, meanwhile, the flow of water flow on the inner wall of the pipe body is more complex due to the staggered diamond-shaped protrusions, more turbulence and vortex are formed, and the heat loss in the pipeline is reduced.
Further, the diamond-shaped protrusions 21 of the a layer are x, a gap between two adjacent diamond-shaped protrusions 21 of the a layer is a0, the diamond-shaped protrusions 21 of the b layer is y, and a gap between two adjacent diamond-shaped protrusions 21 of the b layer is b0, wherein each x is arranged corresponding to one b0, and each y is arranged corresponding to one a 0.
In this embodiment, it is explained how to stagger, preferably, the acute angle of x is on the same straight line as the midpoint of b0, and the acute angle of y is on the same straight line as the midpoint of a0, to accomplish equidistant placement between each x and y.
Further, the distance of the gap between adjacent x and y is 0.25±0.2mm.
In this embodiment, the gap between the adjacent x and y corresponds to a portion of the heat sink 22, and the total contact area of the gap is reduced too large, so that the water flow is difficult to pass through the heat sink 22 with too small a gap, and the distance between the gaps further optimizes the heat exchange performance.
Further, the distance between the obtuse angles of adjacent x and y is 0.8±0.1mm.
In this embodiment, the distance of this interval is further optimized for heat exchange performance, as in the principle described above.
Further, the annular layers 23 are equidistantly arranged, and the diamond-shaped protrusions 21 in the annular layers 23 are equidistantly arranged.
In this embodiment, the equidistant arrangement ensures that the gaps between the annular layers and between the diamond-shaped protrusions are the same in size, so that heat can be uniformly distributed on the inner wall of the pipe body.
Further, the height of the diamond-shaped protrusions 21 is 0.3±0.1mm.
In this embodiment, the height will directly affect the contact area between the pipe body and the water flow, but should not be too high, otherwise, the normal passing of the water flow will be affected, and the diamond-shaped protrusions 21 in this height section can obtain the best heat dissipation effect.
Further, the distance between the acute angles of two adjacent diamond-shaped protrusions 21 is 0.92±0.05mm, so as to obtain the best heat dissipation effect.
Further, the side length of the bottom surface of the diamond-shaped protrusion 21 is 0.64±0.2mm, so as to obtain the best heat dissipation effect.
The working principle of the utility model is as follows:
the inner wall of the pipe body 1 is provided with a pattern part 2, wherein the pattern part 2 is formed by arranging a plurality of diamond-shaped bulges 21, the diamond-shaped bulges 21 are arranged at intervals, and gaps among the diamond-shaped bulges 21 are communicated with each other to form a heat dissipation groove 22 for heat exchange, when water flows through the heat dissipation groove 22, the diamond-shaped bulges 21 are uniformly distributed in the inner wall of the pipe body 1, namely, the side surfaces of a plurality of diamond-shaped bulges 21 are increased, so that the contact area for heat exchange is increased, the heat exchange efficiency of the pipe body and the water flow is improved, namely, the heat dissipation efficiency of the pipe body is improved
