[0037] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0038] Reference will be made below to Figures 1 - 5 Describe the heat exchange device 100 according to the first aspect embodiment of the present utility model.

[0039] As Figures 1 - 5 shown, the heat exchange device 100 according to the first aspect embodiment of the present utility model includes: a heat exchange component 10, and the heat exchange component 10 includes: a first heat exchange tube 11 and a second heat exchange tube 12.

[0040] The number of the first heat exchange tubes 11 is multiple. The multiple first heat exchange tubes 11 extend along a first direction and are spaced apart in a second direction and are connected in sequence. The first heat exchange tube 11 includes two main tubes 111 and multiple branch tubes 112. The two main tubes 111 are spaced apart in the first direction. The multiple branch tubes 112 are connected in parallel between the two main tubes 111. The first direction intersects with the second direction; the second heat exchange tube 12 is connected between two adjacent first heat exchange tubes 11.

[0041] The number of the first heat exchange tubes 11 is multiple. For example, the number of the first heat exchange tubes 11 can be two, three, four, five, six or more. The multiple first heat exchange tubes 11 are arranged at intervals in the second direction and are connected in sequence. Further, the multiple first heat exchange tubes 11 are parallel to each other and arranged at equal intervals in the second direction. The first heat exchange tube 11 includes two main tubes 111 and multiple branch tubes 112. The multiple branch tubes 112 are arranged between the two main tubes 111. The multiple branch tubes 112 are connected in parallel between the two main tubes 111. Both the main tube 111 and the branch tube 112 extend along the first direction. The number of the branch tubes 112 in one first heat exchange tube 11 can be multiple. For example, the number of the branch tubes 112 in one first heat exchange tube 11 can be two, three, four, five, six or more. Further, one ends of the multiple branch tubes 112 intersect with each other in the first direction and are connected to one end of one main tube 111, and the other ends of the multiple branch tubes 112 intersect with each other in the first direction and are connected to one end of the other main tube 111. Further, the two main tubes 111 and the multiple branch tubes 112 in one first heat exchange tube 11 can be manufactured by an integral molding method.

[0042] The second heat exchange tube 12 is connected between two adjacent first heat exchange tubes 11. For example, one end of the second heat exchange tube 12 is connected to one first heat exchange tube 11, and the other end of the second heat exchange tube 12 is connected to another first heat exchange tube 11. The two aforementioned first heat exchange tubes 11 are connected through the aforementioned second heat exchange tube 12. Further, the materials of the first heat exchange tube 11 and the second heat exchange tube 12 can both adopt aluminum alloy. Aluminum alloy has good heat conduction performance. At the same time, it has the advantages of high strength, light weight, low cost, easy processing, corrosion resistance and recyclability.

[0043] It should be noted that in a specific example, the first direction is the direction where the X-axis of the space rectangular coordinate system is located, and the second direction is the direction where the Y-axis of the space rectangular coordinate system is located.

[0044] In this embodiment, when the heat exchange device 100 works, the refrigerant flows into the heat exchange device 100 and sequentially flows through the multiple first heat exchange tubes 11 and the second heat exchange tubes 12. When the refrigerant flows in one first heat exchange tube 11, the refrigerant flows from one of the main tubes 111 to the multiple branch tubes 112 and performs a dispersed flow in the multiple branch tubes 112, thereby completing the flow heat exchange work of the refrigerant in the multiple branch tubes 112 of one first heat exchange tube 11, and thus effectively increasing the contact area between the refrigerant per unit volume and the heat exchange device 100. Then, the refrigerant in the multiple branch tubes 112 converges into the other main tube 111, and thus, the convergence work of the refrigerant is completed.

[0045] After the refrigerant converges in another main pipe 111, it flows towards the second heat exchange pipe 12. In the second heat exchange pipe 12, the refrigerant can complete the mixing work, thus avoiding the phenomenon of uneven temperature of the refrigerant in the second heat exchange pipe 12, and further effectively improving the heat exchange effect of the heat exchange device 100. After the refrigerant completes the mixing work in the second heat exchange pipe 12, it flows to the next first heat exchange pipe 11 to complete further heat exchange work. The refrigerant continuously flows in multiple first heat exchange pipes 11 and second heat exchange pipes 12 for heat exchange work. Finally, after the refrigerant completes the heat exchange work, it flows out of the heat exchange device 100. In addition, the first heat exchange pipe 11 and the second heat exchange pipe 12 have a simple structure and a small volume. The multiple first heat exchange pipes 11 extend along the first direction and are arranged at intervals in the second direction and are connected in sequence, thereby being able to simplify the structural configuration of the heat exchange device 100 and save installation space.

[0046] It should be noted that the refrigerant, also known as the refrigerating agent, can complete the thermodynamic cycle work of gasification and heat absorption or condensation and heat release in the heat exchange device 100, thereby completing the transfer of heat and achieving the purpose of refrigeration or heating.

[0047] According to the heat exchange device 100 of the embodiment of the present invention, by arranging a plurality of first heat exchange pipes 11 and second heat exchange pipes 12 connected between two adjacent first heat exchange pipes 11 in the heat exchange device 100, and setting the first heat exchange pipe 11 to include a plurality of branch pipes 112 arranged in parallel, the contact area of the refrigerant per unit volume with the heat exchange device 100 can be effectively increased and the refrigerant can be fully mixed, thereby effectively increasing the heat exchange area of the heat exchange device 100, and further effectively improving the heat exchange efficiency of the heat exchange device 100. In addition, the heat exchange device 100 has a simple structure and a small volume, can effectively save the installation space, and improve the assembly efficiency.

[0048] In an embodiment of the present invention, as Figure 2 and Figure 3 shown, the multiple branch pipes 112 of the first heat exchange pipe 11 are arranged in the third direction, and the third direction intersects the first direction and the second direction pairwise.

[0049] For example, the multiple branch pipes 112 of the first heat exchange pipe 11 are arranged at intervals in the third direction. Further, the multiple branch pipes 112 of the first heat exchange pipe 11 can be arranged at equal intervals in the third direction. The multiple branch pipes 112 can be parallel to each other and the cross-sectional areas of the multiple branch pipes 112 are the same. It should be noted that in a specific example, the third direction is the direction where the Z-axis of the spatial rectangular coordinate system is located.

[0050] In this embodiment, by arranging a plurality of branch pipes 112 of the first heat exchange pipe 11 in the third direction, it is possible to ensure that when the refrigerant flows through the plurality of branch pipes 112 of the first heat exchange pipe 11, each branch pipe 112 can be filled simultaneously, so that the refrigerant can flow dispersedly and evenly in the plurality of branch pipes 112, thereby effectively improving the heat exchange efficiency. In addition, the structure of the heat exchange member 10 can be made more compact.

[0051] In one embodiment of the present utility model, as Figures 2 - 4 shown, the second heat exchange pipe 12 is a U-shaped bent pipe that opens towards a plurality of first heat exchange pipes 11 in the first direction. For example, the second heat exchange pipe 12 is a U-shaped bent pipe, and the opening at one end of the U-shaped bent pipe faces the main pipe 111 of one first heat exchange pipe 11 and is connected to the main pipe 111, and the opening at the other end of the U-shaped bent pipe faces the main pipe 111 of another first heat exchange pipe 11 and is connected to the main pipe 111.

[0052] In this embodiment, by setting the second heat exchange pipe 12 as a U-shaped bent pipe that opens towards a plurality of first heat exchange pipes 11 in the first direction, it is possible to effectively increase the contact area between the refrigerant and the second heat exchange pipe 12. At the same time, it can change the flow direction of the refrigerant to adapt to the installation space. Compared with a pipeline connected linearly, the number of joints can be reduced, thereby effectively reducing the risk of refrigerant leakage and effectively reducing the accessories required for installation and disassembly.

[0053] In one embodiment of the present utility model, as Figures 2 - 4 shown, the first heat exchange pipe 11 and the second heat exchange pipe 12 are detachably connected. For example, one end of the main pipe 111 of the first heat exchange pipe 11 is detachably connected to one end of the second heat exchange pipe 12.

[0054] When the first heat exchange pipe 11 or the second heat exchange pipe 12 is damaged, the first heat exchange pipe 11 or the second heat exchange pipe 12 can be disassembled or replaced separately, which is convenient for maintenance and repair. In addition, the detachable connection between the first heat exchange pipe 11 and the second heat exchange pipe 12 can facilitate transportation, installation and on-site assembly, thereby reducing logistics and installation costs.

[0055] Therefore, by setting the first heat exchange pipe 11 and the second heat exchange pipe 12 to be detachably connected, the maintenance and repair costs can be effectively reduced. In addition, the logistics and installation costs can also be effectively reduced.

[0056] In one embodiment of the present utility model, as Figures 2 - 4As shown, the main pipe 111 of the first heat exchange pipe 11 is inserted into and threadedly connected to the second heat exchange pipe 12. For example, a threaded structure is provided on the outer wall surface of one end of the main pipe 111 of the first heat exchange pipe 11, and threaded structures are provided on the inner wall surfaces of both ends of the second heat exchange pipe 12. One end of the second heat exchange pipe 12 is inserted into and threadedly connected to one end of the main pipe 111 of a first heat exchange pipe 11, and the other end of the second heat exchange pipe 12 is inserted into and threadedly connected to one end of the main pipe 111 of another first heat exchange pipe 11.

[0057] Through the insertion, the main pipe 111 of the first heat exchange pipe 11 and the second heat exchange pipe 12 can be quickly aligned and preliminarily fixed, thereby enabling rapid assembly and disassembly. On the basis of the insertion, the threaded connection between the main pipe 111 of the first heat exchange pipe 11 and the second heat exchange pipe 12 can further reinforce the connection. The threaded connection provides a firm mechanical fixation, can withstand high pressures and temperature changes, and at the same time ensures the tightness of the connection and prevents refrigerant leakage.

[0058] Thus, by inserting and threadedly connecting the main pipe 111 of the first heat exchange pipe 11 and the second heat exchange pipe 12, the assembly efficiency and disassembly efficiency can be effectively improved. In addition, the stability and safety of the heat exchange device 100 can be effectively improved, thereby effectively ensuring the heat exchange effect of the heat exchange device 100.

[0059] In an embodiment of the present invention, as Figure 4 and Figure 5 shown, the heat exchange device 100 further includes a stirring member 20. The stirring member 20 is disposed inside the second heat exchange pipe 12, and the stirring member 20 is configured to be suitable for stirring the fluid inside the second heat exchange pipe 12.

[0060] For example, one stirring member 20 is provided inside each second heat exchange pipe 12, and the number of the stirring members 20 is the same as the number of the second heat exchange pipes 12. When the heat exchange device 100 operates, the stirring member 20 can stir the refrigerant inside the second heat exchange pipe 12, so that the refrigerant inside the second heat exchange pipe 12 is further mixed, avoiding local overheating or overcooling of the refrigerant.

[0061] Thus, by providing the stirring member 20 inside the second heat exchange pipe 12, the laminar flow state of the refrigerant can be effectively disrupted, so that the refrigerant inside the second heat exchange pipe 12 is fully mixed, thereby effectively ensuring the consistency and controllability of the heat exchange process and improving the heat exchange efficiency.

[0062] In an embodiment of the present invention, as Figure 4 and Figure 5As shown, the stirring member 20 includes a rotating shaft 21 and a plurality of blades 22. The rotating shaft 21 is rotatably disposed within the second heat exchange tube 12. The plurality of blades 22 are arranged at intervals along the circumference of the rotating shaft 21. One end of the blade 22 is connected to the rotating shaft 21 and the other end extends radially outward along the rotating shaft 21.

[0063] Specifically, the number of blades 22 of the stirring member 20 can be multiple. For example, the number of blades 22 of the stirring member 20 can be two, three, four, five, six or more. The plurality of blades 22 are arranged along the circumference of the rotating shaft 21 and are evenly spaced. One end of each blade 22 is fixed to the rotating shaft 21, and the other end of each blade 22 extends radially outward along the rotating shaft 21. Further, the materials of the rotating shaft 21 and the plurality of blades 22 can be made of aluminum alloy. Further, a rotating sleeve 23 can be provided between the rotating shaft 21 and the plurality of blades 22. The rotating sleeve 23 is sleeved outside the rotating shaft 21 and is fixedly connected to the rotating shaft 21. The plurality of blades 22 are arranged along the circumference of the rotating sleeve 23 and are evenly spaced.

[0064] When the stirring member 20 operates, the plurality of blades 22 rotate together with the rotating shaft 21. The blades 22 can generate strong vortex motion through rotation, thereby breaking the boundary layer of the refrigerant, reducing the thermal resistance, and making the heat transfer between the refrigerant and the wall surface of the second heat exchange tube 12 more effective. It should be noted that the boundary layer is a thin layer formed when the fluid approaches the solid surface, where the fluid velocity is low and the heat transfer efficiency is also low. Therefore, by stirring the refrigerant, the heat transfer efficiency can be further improved.

[0065] In this embodiment, by providing the rotating shaft 21 and the plurality of blades 22 in the stirring member 20, the performance of the stirring member 20 can be significantly improved, the stirring effect of the stirring member 20 on the refrigerant can be effectively enhanced, and thus the mixing effect of the refrigerant can be further optimized. In addition, it can also make the heat transfer between the refrigerant and the wall surface of the second heat exchange tube 12 more effective, thereby further improving the heat exchange efficiency.

[0066] In an embodiment of the present invention, as Figure 4 and Figure 5 shown, in the direction from the inside to the outside in the radial direction of the rotating shaft 21, the blade 22 extends along an arc convex on one side in the circumferential direction towards the rotating shaft 21. For example, the projection shape of the blade 22 in the direction perpendicular to the axial direction of the rotating shaft 21 is circular arc-shaped.

[0067] In this embodiment, by arranging the blade 22 to extend along an arc convex on one side in the circumferential direction towards the rotating shaft 21 in the direction from the inside to the outside in the radial direction of the rotating shaft 21, the flow of the refrigerant can be effectively guided, the friction and collision between the blade 22 and the refrigerant can be reduced, thereby effectively reducing the resistance of the refrigerant flow, and further effectively reducing the wear and noise of the blade 22.

[0068] In an embodiment of the present invention, asFigure 4 and Figure 5 As shown in Figure 5 , the stirring member 20 further includes a bracket 24. The bracket 24 is fixed to the inner wall of the second heat exchange tube 12. A shaft hole is formed on the bracket 24, and the rotating shaft 21 is rotatably fitted in the shaft hole. For example, the bracket 24 is fixedly connected to the inner wall of the second heat exchange tube 12, and the rotating shaft 21 is rotatably arranged in the shaft hole. Further, the number of the brackets 24 can be two, and the brackets 24 can be symmetrically arranged at both ends of the rotating shaft 21, and both ends of the rotating shaft 21 are respectively arranged in the shaft holes of the two brackets 24.

[0069] When the stirring member 20 works, the bracket 24 can bear the load acting in the radial and axial directions from the rotating shaft 21, so as to ensure that the rotating shaft 21 and the blades 22 will not have unnecessary offset or vibration during rotation, so that the stirring member 20 can work continuously and stably.

[0070] In this embodiment, by arranging the bracket 24 in the stirring member 20, the offset and vibration during the rotation of the rotating shaft 21 and the blades 22 can be effectively avoided, thereby effectively ensuring the stability and reliability of the stirring member 20.

[0071] In an embodiment of the present utility model, as Figure 4 and Figure 5 shown, the bracket 24 includes a supporting portion 241 and fixing rods 242. The supporting portion 241 is annular and defines a shaft hole inside. The number of the fixing rods 242 is multiple and they are arranged at intervals along the circumferential direction of the supporting portion 241. One ends of the multiple fixing rods 242 are connected to the supporting portion 241, and the other ends extend radially outward along the shaft hole to be connected to the inner wall of the second heat exchange tube 12.

[0072] The shape of the supporting portion 241 is annular and a shaft hole is formed inside. The number of the fixing rods 242 is multiple. For example, the number of the fixing rods 242 can be two, three, four, five, six or more. Further, the cross-sectional shape of the fixing rods 242 can be rectangular. The fixing rods 242 are evenly arranged at intervals along the circumferential direction of the annular supporting portion 241. One end of each fixing rod 242 is fixedly connected to the supporting portion 241, and the other end of each fixing rod 242 extends radially outward along the shaft hole to be fixedly connected to the inner wall of the second heat exchange tube 12. Further, the materials of the fixing rods 242 and the supporting portion 241 can be made of aluminum alloy.

[0073] In this embodiment, by arranging the annular supporting portion 241 and the multiple fixing rods 242 arranged at intervals along the circumferential direction of the supporting portion 241 in the bracket 24, the structural strength of the bracket 24 can be effectively improved, and the bracket 24 can be prevented from undergoing excessive deformation when bearing the forces transmitted by the rotating shaft 21 and the refrigerant, thereby effectively improving the supporting effect of the bracket 24.

[0074] In an embodiment of the present utility model, as Figure 1 andFigure 2 As shown in the figure, the heat exchange member 10 further includes a first inlet / outlet pipe 13 and a second inlet / outlet pipe 14, and the first inlet / outlet pipe 13 and the second inlet / outlet pipe 14 are respectively connected to both ends of a plurality of first heat exchange pipes 11.

[0075] For example, one end of the first inlet / outlet pipe 13 is connected to the main pipe 111 of a first heat exchange pipe 11. Further, the connection mode between one end of the first inlet / outlet pipe 13 and the main pipe 111 of a first heat exchange pipe 11 can adopt welding. For example, one end of the second inlet / outlet pipe 14 is connected to the main pipe 111 of another first heat exchange pipe 11. Further, the connection mode between one end of the second inlet / outlet pipe 14 and the main pipe 111 of another first heat exchange pipe 11 can adopt welding. Further, the materials of the first inlet / outlet pipe 13 and the second inlet / outlet pipe 14 can adopt aluminum alloy.

[0076] When the heat exchange device 100 works, the refrigerant enters the heat exchange device 100 from the first inlet / outlet pipe 13, flows through a plurality of first heat exchange pipes 11 and a plurality of second heat exchange pipes 12 from the first inlet / outlet pipe 13 to complete the heat exchange work, and then flows out of the heat exchange device 100 from the second inlet / outlet pipe 14.

[0077] In this embodiment, by providing the first inlet / outlet pipe 13 and the second inlet / outlet pipe 14 in the heat exchange member 10, an outlet and an inlet for the refrigerant to flow can be provided, so that the refrigerant can flow into and out of the heat exchange device 100 orderly, and further ensure the effective progress of the heat exchange work.

[0078] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the heat exchange device 100 further includes an installation frame 30. The installation frame 30 is rectangular ring-shaped and defines an installation space inside. A first through hole and a second through hole that penetrate the installation frame 30 along the thickness direction of the installation frame 30 are formed on the installation frame 30. The heat exchange member 10 is arranged in the installation space. One end of the first inlet / outlet pipe 13 penetrates through the first through hole, and one end of the second inlet / outlet pipe 14 penetrates through the second through hole. For example, the installation frame 30 has upper, lower, left and right side walls. Further, the first through hole is arranged at the upper position of the left side wall of the installation frame 30, and the second through hole is arranged at the lower position of the right side wall of the installation frame 30.

[0079] In this embodiment, by providing the installation frame 30 in the heat exchange device 100 and providing the first through hole and the second through hole on the installation frame 30, an installation space can be provided for the heat exchange member 10 and the first inlet / outlet pipe 13 and the second inlet / outlet pipe 14 can be effectively fixed, so that the heat exchange member 10 can be effectively protected and enclosed, and further the safety of the heat exchange device 100 can be effectively improved.

[0080] In an embodiment of the present utility model, as Figure 1As shown, the heat exchange device 100 further includes dust-proof plates. The number of dust-proof plates is two.
