Since the heat exchange tubes are important heat exchange and pressure-bearing units for heat exchange, the improvement of the energy efficiency of the heat exchanger depends to a greater extent on the performance of the heat exchange tubes used. Therefore, the development of more efficient and more economical heat exchange tubes has become one of the key and hot research areas for major air-conditioning manufacturers.
[0003] During the heat transfer process, there is always a certain resistance when heat is transferred through the heat exchange tube, and this resistance is called the heat transfer resistance.

In the prior art, the heat exchange tube adopts a T-shaped boiling surface, and the saturated refrigerant liquid directly rushes from the surface of the heat exchange tube to the exposed nucleation sites, which will cause the nucleation points to fail and result in low heat exchange efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0031] According to an embodiment of the present utility model, a heat exchange structure is provided. Please refer to Figures 1 to 6, including: a substrate 1, with heat exchange fluids arranged on both sides of the substrate 1, and the substrate 1 is used for exchanging the heat of the heat exchange fluids on both sides; an overheating component 2, which is arranged on the substrate 1, and the overheating component 2 and the substrate 1 enclose an overheating gap 21; the overheating component 2 has an overheating part 22 for contacting the heat exchange fluid entering the overheating gap 21; an overheating groove 3, which is recessed on the outer surface of the substrate 1, and the overheating groove 3 has a first side wall 31 and a second side wall 32, and the distance between the first side wall 31 and the second side wall 32 gradually increases in the direction away from the outer surface of the substrate 1.
[0032] With the above settings, the heat exchange fluids on both sides of the substrate 1 transfer the heat on one side to the other side through the substrate 1. There is a certain overheating gap 21 between the overheating component 2 and the substrate 1. The heat exchange fluid on one side of the substrate 1 enters the overheating gap 21 through the overheating part 22, reducing the superheat required for the heat exchange fluid to evaporate, which is beneficial to the formation of evaporation bubbles. When the liquid on the surface of the heat exchange structure is heated above its saturation temperature, evaporation bubbles will form. As the size of the evaporation bubbles increases until the surface tension is overcome by the buoyancy and momentum forces, the evaporation bubbles detach from the surface of the heat exchange structure. The evaporation of the liquid, the continuous peeling of the heated liquid adjacent to the heat transfer surface, and the convective effect caused by the rising of the bubbles stirring the liquid pool can all improve the heat transfer rate on the surface of the heat exchange structure. After the heat exchange fluid enters the overheating gap 21, the overheating groove 3 strengthens the disturbance of the heat exchange fluid entering the overheating gap 21 while increasing the contact area between the heat exchange fluid and the substrate 1, improving the heat exchange efficiency of the heat exchange structure and solving the technical problem of low heat exchange efficiency of the heat exchange tube in the related technology.
[0033] Specifically, the heat exchange fluid includes a high-temperature fluid and a boiling medium.
[0034] In the heat exchange structure of this embodiment, refer to Figure 6 , the substrate 1 extends circumferentially to enclose a heat exchange cavity inside the substrate 1, and the overheating component 2 is arranged on the side of the substrate 1 away from the heat exchange cavity. In this way, the high-temperature fluid flows in the heat exchange cavity, and the boiling medium is outside the heat exchange cavity, and the two transfer heat through the substrate 1.
[0035] In the heat exchange structure of this embodiment, refer to Figure 1, the overheat component 2 includes: a connection part 23, the connection part 23 protrudes from the outer surface of the base body 1, and the connection part 23 extends in a direction away from the heat exchange cavity; the overheat part 22 is connected to one end of the connection part 23 away from the base body 1, the overheat part 22 extends along the axial direction of the heat exchange cavity, and the shortest distance between the overheat part 22 and the base body 1 gradually increases. In this way, there is an inclination angle between the overheat part 22 and the base body 1. After the boiling medium passes through the overheat part 22 and enters the overheat gap 21, the boiling medium can be superheated at the overheat part 22. When it enters the overheat gap 21, a relatively large heat flux is not required to make the boiling medium reach the initial boiling point, which is beneficial to the formation of evaporation bubbles.
[0036] In the heat exchange structure of this embodiment, refer to Figure 3 , one side of the overheat part 22 away from the base body 1 has a first overheat surface 221 in contact with the heat exchange fluid; a second overheat surface 222 in contact with the heat exchange fluid is arranged on the side of the overheat part 22 away from the first overheat surface 221. In this way, both the first overheat surface 221 and the second overheat surface 222 can be in contact with the boiling medium, so that the boiling medium can absorb heat more fully, so that the heat required for the boiling medium to boil after reaching the overheat gap 21 is less.
[0037] In the heat exchange structure of this embodiment, refer to Figure 3 , there is an overheat channel 223 between the first overheat surface 221 and the second overheat surface 222, and the overheat channel 223 is used for the heat exchange fluid to flow through. In this way, by controlling the distance between the first overheat surface 221 and the second overheat surface 222, the size of the opening entering the overheat gap 21 can be effectively controlled, so that the boiling medium entering the overheat gap 21 can better form evaporation bubbles.
[0038] In the heat exchange structure of this embodiment, refer to Figure 3 , an evaporation protrusion 25 is arranged on the connection part 23, the evaporation protrusion 25 extends along the axial direction of the heat exchange cavity in a direction away from the connection part 23, and the evaporation protrusion 25 and the base body 1 enclose an evaporation cavity 251, and the evaporation cavity 251 is communicated with the overheat gap 21. In this way, the evaporation protrusion 25 encloses a relatively closed evaporation cavity 251 in the overheat gap 21. While increasing the heat exchange area of the boiling medium, it provides the cavity structure required for the evaporation of the boiling medium and improves the heat exchange efficiency of the heat exchange structure.
[0039] In the heat exchange structure of this embodiment, refer to Figures 1 to 2, the heat exchange structure further includes an evaporation groove 4, which is recessed in the outer surface of the base body 1. The cross-sectional area of the evaporation groove 4 gradually decreases in the direction away from the superheat part 22, and the evaporation groove 4 communicates with the evaporation chamber 251. In this way, the evaporation groove 4 is arranged at the bottom of the superheat gap 21, increasing the heat exchange area between the base body 1 and the boiling medium. At the same time, the structure of the evaporation groove 4 is conducive to the superheating of the boiling medium, providing the superheat required for the formation of evaporation bubbles in the boiling medium.
[0040] Preferably, there are multiple evaporation grooves 4, and the multiple evaporation grooves 4 are arranged at intervals, which is conducive to the formation of vaporization nuclei required for the evaporation of the boiling medium.
[0041] In the heat exchange structure of this embodiment, refer to Figures 4 to 5 , the cross-sectional area of the connecting part 23 gradually decreases in the direction away from the heat exchange chamber; the cross-sectional area of the superheat part 22 gradually decreases in the direction away from the connecting part 23. In this way, the gap between two adjacent superheat parts 22 along the circumferential direction of the heat exchange chamber provides an inlet hole and a bubble escape hole for the boiling medium required for evaporation. There is a certain gap between two adjacent superheat components 2 along the circumferential direction of the heat exchange chamber, which can increase the heat exchange area between the superheat component 2 and the boiling medium, and at the same time provides a cavity structure required for the evaporation of the boiling medium to form bubbles, improving the heat exchange efficiency of the heat exchange structure.
[0042] Preferably, the gap between two adjacent superheat parts 22 along the circumferential direction of the heat exchange chamber is an inverted V shape; there is an inverted V-shaped gap between two adjacent superheat components 2 along the circumferential direction of the heat exchange chamber.
[0043] In the heat exchange structure of this embodiment, refer to Figure 5 , there are multiple superheat components 2, and the multiple superheat components 2 are arranged at intervals along the axial direction of the heat exchange chamber; and / or, the multiple superheat components 2 are arranged at intervals along the circumferential direction of the heat exchange chamber. In this way, multiple superheat parts 22 and the base body 1 enclose a superheat gap 21, and multiple evaporation protrusions 25 and the base body 1 enclose an evaporation chamber 251, providing conditions for the evaporation of the boiling medium and improving the heat exchange efficiency of the heat exchange structure.
[0044] In the heat exchange structure of this embodiment, refer to Figure 4 , on the side of the base body 1 away from the superheat component 2, there are heat exchange protrusions 5, and there are multiple heat exchange protrusions 5, and the multiple heat exchange protrusions 5 are arranged at intervals. In this way, the arrangement of the multiple heat exchange protrusions 5 can increase the contact area with the high-temperature fluid in the heat exchange chamber and improve the heat exchange efficiency.
[0045] Preferably, the multiple heat exchange protrusions 5 are arranged along the circumferential direction of the heat exchange chamber.
[0046] Embodiment 2:
[0047] This embodiment provides a heat exchanger, including the above heat exchange structure.
[0048] Specifically, referring to Figure 6 , the enhanced evaporation tube for a falling film evaporator in a compression refrigeration unit mainly includes a heat exchange tube matrix 1. Among them, the matrix 1 is used to transfer the heat of the heat source on one side to the boiling medium on the other side. An overheating component 2 is arranged on the outer side of the matrix 1. The overheating component 2 and the matrix 1 are integrated. There is a certain overheating gap 21 between two adjacent overheating components 2 along the axial direction of the heat exchange tube. There are evaporation grooves 4 arranged at intervals at one end of two adjacent overheating components 2 close to the matrix 1 along the axial direction of the heat exchange tube. There is an inverted "Ω"-shaped overheating groove 3 between two adjacent evaporation grooves 4 in the circumferential direction. There are evaporation protrusions 25 and an inverted V-shaped gap between two adjacent overheating components 2 along the circumferential direction of the heat exchange tube. There are heat exchange protrusions 5 extending towards the inside of the tube inside the heat exchange tube, and the protrusions extend spirally towards both ends inside the tube. The protrusions are distributed in multiple heads inside the tube and can be evenly distributed or unevenly distributed.
[0049] The overheating component 2 and the matrix 1 are integrated. There is a certain overheating gap 21 between the two fins, and this gap is formed by extrusion molding. First, it increases the heat exchange area, and second, it provides the cavity structure required for evaporation. The overheating part 22 at the top of the overheating component 2 is of an inclined structure. When the refrigerant outside the tube enters the overheating gap 21, it will pass through the overheating part 22, and the refrigerant will be superheated on the overheating part 22. In this way, the superheat required during evaporation will be reduced, which is beneficial to the formation of evaporation bubbles.
[0050] Preferably, the overheating components 2 are evenly distributed along the axial direction of the heat exchange tube.
[0051] There is an inverted V-shaped gap between two adjacent overheating parts 22, which provides the inlet hole for the refrigerant required for evaporation and the bubble escape hole. And one end of the overheating part 22 obliquely covers the upper part of the adjacent overheating part 22, so that the refrigerant must pass through the overheating part 22 before entering the overheating gap 21. In this way, the superheat required during evaporation will be reduced, which is beneficial to the formation of evaporation bubbles.
[0052] An evaporation protrusion 25 is arranged between two adjacent connecting parts 23. The evaporation protrusion 25 extends towards both sides of the overheating component 2 ≤ the distance between two overheating components 2. In this way, an opening will be formed at the top of the evaporation cavity 251 for the entry of the refrigerant liquid and the escape of evaporation bubbles.
[0053] The evaporation protrusions 25 are evenly distributed in the circumferential direction.
[0054] Evaporation grooves 4 are formed at the bottom between the overheating components 2. This structure forms a certain depth towards the inside of the tube matrix 1, increasing the heat exchange area while being beneficial to the superheating of the refrigerant, providing the superheat required for the formation of evaporation bubbles, and being beneficial to the formation of the vaporization nuclei required for evaporation.
[0055] The tube has heat exchange protrusions 5 inside. The fluid inside the heat exchange tube is a single-phase fluid, generally water. The heat exchange protrusions 5 increase the disturbance of the fluid inside the tube and strengthen the heat exchange inside the tube. The heat exchange protrusions 5 are spirally distributed along the inside of the tube, and this protrusion structure is distributed in multiple heads in the circumferential direction.
[0056] The heat exchange structure of the present utility model is rolled by a special fin rolling mill, and the fin types inside and outside the tube are integrally formed. The specific processing process outside the tube is as follows:
[0057] First, a combined blade is used to process spiral fins on one side of the heat transfer tube substrate 1. At the same time, a special knurling tool is used to cut the spiral fins into multiple independent overheat components 2, and evaporation protrusions 25 are formed on both sides of the overheat components 2 by extrusion. Subsequently, an inclined rolling tool is used to roll the overheat components 2 into fin tops with bent fins, and a special tool is used to press concave bosses on the fins at the connecting part 23. Then, a forming tool is used to extrude an evaporation groove 4 between the two bosses, and a flat head tool is used to extrude to form an inverted "Ω" structure. Multiple threads are provided inside the substrate 1, and through the combined action of an external tube tool extrusion and an internal tube mold, multi-headed heat exchange protrusions 5 are formed inside the tube. The use of rolling and spinning technologies in processing does not increase the manufacturing materials of the heat transfer tube, which not only saves production costs but also increases the strength and heat transfer area of the heat transfer tube.
