[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 12 The heat exchange assembly shown includes a heat exchange tube 1 and a connector 2 connected to the surface of an object. The heat exchange tube 1 includes a heat exchange tube body 3 located outside the connector 2, a heat exchange tube inlet 4 connected to the heat exchange tube body 3 and for medium to enter, and a heat exchange tube outlet 5 connected to the heat exchange tube body 3 and for medium to discharge. The connector 2 is provided with a first connection layer on the side facing the heat exchange tube body 3. The utility model can reduce the occupied space of the heat exchange assembly by arranging a connector on the surface of an object, and the heat exchange tube is connected to the connector through the first connection layer. The heat exchange tube will not be shortened due to scale or water quality. At the same time, the connection method of the connector and the heat exchange tube is simple, which can effectively improve the assembly efficiency. The heat exchange tube exchanges heat with the surface of the object through the connector, further increasing the heat exchange area and effectively improving the heat exchange efficiency.

[0031] Optionally, in some embodiments, the heat exchange component can be used in a heating device, and the heat exchange tube can accelerate the preheating speed, and exchange heat with the high-temperature surface of the object during the movement of the low-temperature medium in the heat exchange tube, thereby further accelerating the temperature of the medium in the heat exchange tube.

[0032] Optionally, in some embodiments, the heat exchange component can be used in a refrigeration device, and the heat exchange tube can allow refrigerant to pass through. The refrigerant in the heat exchange tube takes away the high temperature on the surface of the object and performs heat exchange during the movement, which can speed up the cooling speed inside the object.

[0033] Specifically, for the coil-wrap heat exchange, it is generally connected to the outside of the container by welding so that the copper tube can be stably connected to the outside of the container, and the coil-wrap method is generally arranged in a spiral shape. When welding, it is not possible to form a contact point between every position of the copper tube and the surface of the container. Most of the copper tubes cannot contact the surface of the container, resulting in poor heat exchange efficiency. In addition, the design of the external coil-wrap needs to be processed and bent first and sleeved on the outside of the container. More coil-wrap volume needs to be reserved so that the copper tube can be connected to the surface of the container, resulting in more space being occupied, which indirectly leads to the need to increase the size of the overall equipment. The increase in the size and volume of the copper tube leads to increased costs. In addition, since the copper tube is welded to the outside of the container, when the copper tube leaks and needs to be replaced, it makes installation and disassembly complicated, increasing the difficulty and workload of maintenance.

[0034] The utility model first connects the heat exchange tube to the connecting piece through the first connecting layer, thereby improving the stability of the heat exchange tube. The shape of the heat exchange tube can be set as needed, and does not need to be set in a spiral shape on the connecting piece. The heat exchange tube does not need to be sleeved on the outside of the container, but only needs to be directly connected to the surface of the connecting piece, further reducing the space occupied by the heat exchange tube. Since the connecting piece is in contact with the surface of the object, the heat exchange tube exchanges heat with the surface of the object through the connecting piece, further increasing the heat exchange area and effectively improving the heat exchange efficiency. When the heat exchange tube leaks, the heat exchange tube can be directly disassembled for replacement, and then the heat exchange tube can be connected to the connecting piece through the first connecting layer, or the connecting piece can be directly replaced and then the connecting piece can be reconnected to the surface of the object.

[0035] Specifically, the expansion tube type heat exchange container requires special equipment to be manufactured, resulting in a relatively high manufacturing cost. The expansion tube type heat exchange container requires that the outer layer and the inner layer are made of different materials and have different expansion coefficients, and has high requirements for materials. The heat exchange process is achieved through the thermal expansion and contraction movement of the expansion tube, and relies on heat transfer between the tube wall and the medium, resulting in a relatively low thermal efficiency. Moreover, when scale or impurities exist in the inner or outer tube, it will cause maintenance difficulties and the entire heat exchange container needs to be replaced.

[0036] The manufacturing cost of the utility model is low, and the material requirements are lower than those of the expansion tube type heat exchange container. In addition, the heat transfer efficiency of the utility model is higher than that of the expansion tube type heat exchange container, and it is relatively more convenient to maintain and replace.

[0037] Specifically, the immersion heat exchanger is directly immersed in water and is easily affected by water quality. Especially in an environment with poor water quality, the surface of the immersion heat exchanger is prone to scaling and corrosion, resulting in reduced heat exchange efficiency. In addition, the heating uniformity of the immersion heat exchanger is poor, which will lead to a large temperature difference in the overall local position. The immersion heat exchanger immersed in water is relatively difficult to clean and maintain, and needs to be cleaned and descaled regularly, otherwise it will affect the service life and heating efficiency of the heat exchanger.

[0038] The utility model is not easily affected by water quality, and scale will not be generated on the surface of the heat exchange tube. Since the connecting piece is in contact with the surface of the object, the heat exchange tube exchanges heat with the surface of the object through the connecting piece, which further increases the heat exchange area and effectively improves the heat exchange efficiency. There is no need to frequently clean the heat exchange tube, which reduces the number of maintenance times and there is no need to worry about the problem of efficiency degradation.

[0039] Optionally, in some embodiments, the first connecting layer can be applied between the surface of the heat exchange tube and the connecting piece by an adhesive, and pressure is applied and waited for it to dry or solidify. A hot melt layer can also be formed by a hot melt method and pressure is applied to combine them together. Furthermore, the two can be combined by threaded connection or riveting. In addition, the heat exchange tube and the connecting piece can also be connected by welding.

[0040] In addition, the connector may be bonded to the container surface by an adhesive, or may be connected to the container surface by hot melting, threading, or riveting.

[0041] like Figures 1 to 6 In the heat exchange assembly shown, the connector 2 is an integral arrangement and is continuously formed along the circumference of the object, and its cross section is polygonal. Further, as a preferred embodiment of the utility model but not a limitation, the integrally arranged connector can provide stronger structural strength and rigidity, and can also better adapt to the surfaces of objects of different shapes and sizes, making it easier to install on various heat exchange containers. At the same time, due to its continuously surrounding structure, it can better withstand external stress and impact, and the design formed by continuously surrounding the circumference of the object also makes the connector more firm and reliable, not easy to loosen or fall off, and better improves the stability and reliability of the entire heat exchange assembly.

[0042] The shape of the polygonal cross-section can provide better stability and torsion resistance, allowing the connector to better withstand external forces. The polygonal cross-section design can also increase the contact area between the connector and the surface of the object, which not only enhances the adhesion between the connector and the object, improves the heat conduction efficiency and the heat exchange effect, but also makes the contact area between the connector and the heat exchange tube larger, allowing the heat exchange tube to better fit on the surface of the connector.

[0043] like Figures 7 to 12In the heat exchange assembly shown, there are multiple connectors 2, and the multiple connectors 2 are sequentially arranged along the outer circumference of the object. The shape formed by the multiple connectors 2 surrounding the object has a polygonal cross-section. Further, as a preferred embodiment of the utility model but not a limitation, as an improved heat exchange assembly, this embodiment provides higher flexibility and adaptability, and can be applied to the surfaces of objects of different sizes and shapes. The arrangement of multiple connectors can better disperse the pressure and vibration of the medium, and improve the stability and reliability of the entire heat exchange assembly. At the same time, the shape formed by the multiple connectors surrounding the object can better adapt to the outer circumference of the object, so that it can be more firmly fixed on the surface of the object.

[0044] Specifically, when the container is of a special shape, that is, the outer peripheral surface of the container is composed of multiple side surfaces of different shapes, if the connector is integrally formed, when the connector surrounds the surface of the container, due to the different shapes of each side surface, some connectors may not be able to fully fit on the side surface of the container with a smaller area. If the area of ​​the connector is too small, the side surface of the container with a larger area cannot be fitted with a connector of a suitable area, resulting in low thermal efficiency and inability to fully exchange heat, which will affect the heat exchange effect.

[0045] Optionally, in some embodiments, multiple connectors may be completely fitted onto the sides of the container of different sizes and shapes, respectively. In this case, the multiple connectors will fit as closely as possible to further keep the container surface completely covered by the connectors, thereby reducing heat loss.

[0046] Optionally, in some other embodiments, multiple connectors are selected with uniform shapes and fit over part of the side surface of the container, and the connectors form more of an intermediate layer to facilitate the connection of the heat exchange tubes to the connectors. Such a setting can save costs and facilitate assembly.

[0047] Since the cross-sections of the multiple connectors are polygonal, a larger contact area and better stability can be provided. The polygonal cross-section design can also provide better torsion and bending resistance, further enhancing the strength and stability of the connector.

[0048] like Figures 1 to 12 In the heat exchange assembly shown, the connector 2 is made of one of plastic, stainless steel, aluminum, and copper. Further, as a preferred embodiment of the present invention but not a limitation, the connector design of different materials further enhances the applicability and flexibility of the heat exchange assembly, making it have a wider application prospect in various heat exchange applications.

[0049] For applications that require corrosion resistance, temperature resistance, and high pressure, stainless steel can be selected as the material for connectors, which can withstand heavy loads or in harsh environments; for applications that require light weight, corrosion resistance, and low price, plastic can be selected as the material for connectors; for applications that require light weight, good thermal conductivity, and strong plasticity, plastic can be selected as the material for connectors to accommodate complex shapes; for applications that require high thermal conductivity, copper can be selected as the material for connectors.

[0050] like Figures 1 to 12 In the heat exchange assembly shown, the heat exchange tube 1 is made of one of stainless steel, aluminum, and copper. Further, as a preferred embodiment of the utility model but not a limitation, the stainless steel heat exchange tube has excellent corrosion resistance and oxidation resistance, and is suitable for heat exchange applications in some corrosive media and severe temperatures. The aluminum heat exchange tube has good thermal conductivity and light weight, and is suitable for heat exchange applications under some low pressure and low temperature conditions. The copper heat exchange tube has good thermal conductivity and strength, and is suitable for occasions requiring efficient heat exchange.

[0051] like Figures 1 to 12 In the heat exchange assembly shown, the first connecting layer is a low-temperature resistant adhesive. Furthermore, as a preferred embodiment of the utility model but not a limitation, the adhesive is coated or applied to the surface of the connector, and then the connector and the heat exchange tube are pressed together. The adhesive can form an adhesive layer, so that an adhesive force is generated between the connector and the heat exchange tube, thereby achieving the purpose of connection, simplifying the installation process, and improving the installation efficiency. At the same time, the adhesive has good elasticity and can adapt to the dimensional errors of the heat exchange tube and the connector, further enhancing the reliability of the connection. The adhesive can provide strong adhesion and sealing, can resist the pressure and vibration of the medium, and prevent leakage or loosening at the connection. In addition, the adhesive also has good corrosion resistance and low temperature resistance, and can adapt to various harsh heat exchange environments.

[0052] like Figures 1 to 6 In the heat exchange assembly shown, the heat exchange tube 1 is coiled from the upper side to the lower side along the circumference of the connector 2. Furthermore, as a preferred embodiment of the utility model but not a limitation, the heat exchange tube is coiled from the upper side to the lower side along the circumference of the connector so that the heat exchange tube can be arranged more compactly around the connector, reducing the occupied space, making the entire heat exchange assembly more compact and lightweight, and achieving a tighter and more effective heat exchange, avoiding the problem of increased heat transfer distance caused by the occupied space of the winding tube heat exchanger, resulting in a slower heat transfer rate. By coiling the heat exchange tube along the circumference of the connector, this design can also increase the flow rate and pressure of the fluid in the heat exchange tube, improve the heat transfer effect and reduce the fluid resistance, further increase the surface area of ​​the heat exchange tube, and improve the heat exchange efficiency.

[0053] Optionally, in some embodiments, the heat exchange tube inlet and the heat exchange tube outlet are located on the same side.

[0054] Optionally, in some other embodiments, the heat exchange tube inlet and the heat exchange tube outlet are arranged opposite to each other.

[0055] like Figures 1 to 12 In the heat exchange assembly shown, the heat exchange tube body 3 is provided with a coiled end 31 connected to the connector 2, and a winding end 32, and a plurality of the coiled ends 31 and the winding end 32 are provided, and the winding end 32 is connected between two adjacent coiled ends 31. Further, as a preferred embodiment of the utility model but not a limitation, by tightly fixing the heat exchange tube on the connector and forming a continuous winding detail, the contact force between the heat exchange tube and the connector can be enhanced to ensure better heat transfer efficiency.

[0056] Specifically, the coiled end used to increase the moving stroke can increase the length and heat exchange area of ​​the heat exchange tube and improve the heat exchange efficiency. At the same time, the arrangement of multiple coiled ends and winding ends can make the heat exchange tube more compactly arranged around the connector, reduce the occupied space, and make the entire heat exchange assembly more compact and lightweight. Since each winding end is connected between two adjacent coiled ends, the stability of the heat exchange tube can be increased to prevent it from loosening or falling off.

[0057] Optionally, in some embodiments, the heat exchange tube is a closed cross-section shape formed by continuous coiling. Such a configuration has a compact structure, and the heat exchange tube can completely cover every position of the container, thereby ensuring a good heat exchange effect. Since there is no breakpoint, the closed cross-sectional shape can withstand higher pressure and temperature, and the heat exchange tube has strong stability. The continuity of the cross-sectional shape makes the flow of the fluid in the heat exchange tube smoother, reducing the flow resistance.

[0058] Optionally, in some embodiments, the heat exchange tube is continuously coiled around the outer circumference of the container, the first section of the heat exchange tube and the tail section of the heat exchange tube are not connected, and a gap is left in the cross section formed by the coiling of the heat exchange tube. Such a setting can better adjust the position of the heat exchange tube inlet and the heat exchange tube outlet, so that the heat exchange tube inlet and the heat exchange tube outlet can better match the position of the refrigeration compressor, reduce the stroke of the non-heat exchange pipeline, and save the overall space. At the same time, the shape of the heat exchange tube can be better adjusted according to the different outer side shapes of the container. Leaving a gap can reduce or disperse the risk of stress concentration. In the continuously coiled heat exchange tube, stress concentration may occur due to expansion or contraction caused by temperature differences. Leaving a gap can reduce this stress, avoid damage and rupture, and prevent the heat exchange tube from detaching from the connector.

[0059] like Figures 1 to 12In the heat exchange assembly shown, the coiled end 31 is in one of the shapes of a straight line, a V-shape, a U-shape, a W-shape, a wavy shape, and a bow shape, and the winding end 32 is in one of the shapes of an L-shape, a V-shape, and an arc shape. Further, as a preferred embodiment of the utility model but not a limitation, this design increases the diversity of the shape and structure of the heat exchange tube, and a suitable shape can be selected according to actual needs to optimize the heat exchange effect and fluid flow characteristics. For example, for occasions where a larger heat exchange area is required, a wavy or bow-shaped coiled end can be selected to increase the curvature and heat exchange area of ​​the heat exchange tube; for occasions where the fluid resistance needs to be reduced, a straight-line coiled end can be selected to reduce the flow resistance of the fluid in the heat exchange tube. Specifically, when the container is a rectangular parallelepiped, the heat exchange tube can be continuously coiled in a straight line to form a square shape, or the heat exchange tube can be coiled along the circumference of the rectangular parallelepiped and then repeatedly coiled from top to bottom to form multiple square shapes, and coiled in a spiral shape.

[0060] For the wrap-around end, the L-shaped design may provide additional fixed support and is suitable for square containers. The V-shaped design may increase the stability of the connection and is suitable for situations where the angle between two adjacent side surfaces of the container is not a right angle. The arc shape may help reduce stress concentration and is suitable for situations where the container side is chamfered.

[0061] like Figures 1 to 12 The refrigeration device shown includes a tank body 6, the outer side of the tank body 6 is provided with the heat exchange assembly as described above, the side of the connector 2 facing away from the heat exchange tube body 3 is provided with a second connection layer, and the second connection layer is connected between the connector 2 and the tank body 6. Further, as a preferred embodiment of the utility model but not a limitation, the tank body is usually used to contain the refrigerated medium, and the heat exchange assembly transfers heat to the surface of the tank body through the coolant to achieve a refrigeration effect. Compared with the prior art, the arrangement of the heat exchange assembly on the tank body can not only reduce the problem of space occupied by the heat exchange assembly, but also prevent the heat exchange tube from being shortened due to scale or water quality. At the same time, the connection method of the connector and the heat exchange tube is simple, which can effectively improve the assembly efficiency. The heat exchange tube exchanges heat with the surface of the object through the connector, which further increases the heat exchange area and effectively improves the heat exchange efficiency.

[0062] Optionally, in some embodiments, the refrigeration equipment is provided with a condensing assembly and a compressor assembly, the inlet of the heat exchange tube is connected to the condensing assembly, and the outlet of the heat exchange tube is connected to the compressor assembly, and the refrigerant achieves heat transfer by moving in the evaporating tube.

[0063] Optionally, in some embodiments, a water inlet and a water outlet are provided on the tank body, and liquid can enter the tank body from the water inlet for refrigeration, and the refrigerated water is discharged from the water outlet.

[0064] Specifically, the second connection layer can play a role of fixing and sealing, can enhance the connection stability between the connector and the tank body, prevent the heat exchange component from falling off or loosening during operation, and improve the overall performance and stability of the refrigeration equipment. In addition, the second connection layer can be an adhesive so that the connector can be bonded to the surface of the container, the second connection layer can also be a hot melt layer, or the connector can be connected to the container surface by threaded connection or riveting, or the connector can be connected to the container surface by welding.

[0065] Further, as a preferred embodiment of the present invention but not limiting, in order to improve the connection effect of the second connection layer, the second connection layer is preferably a low-temperature resistant adhesive.

[0066] Further, as a preferred embodiment of the present invention but not limiting, the material used for the tank body is one of glass, metal or plastic. Optionally, in some embodiments, the tank body can be set to food-grade stainless steel, or it can be set to high-density polyethylene or polypropylene. The tank body made of food-grade stainless steel has the characteristics of corrosion resistance, temperature resistance, wear resistance and easy cleaning, and will not release harmful substances into the water. The tank body made of high-density polyethylene has good corrosion resistance and durability, while polypropylene has good temperature resistance and stability. In addition, the glass tank body is easy to clean, will not leave any residual odor, will not release or leak harmful substances, has high transparency, and can be used with drinking water equipment to create a unique appearance, thereby improving its ornamental value. Moreover, the glass tank body can be used with UV disinfection components to sterilize and disinfect the water in the tank body, thereby improving the safety of water use. In addition to choosing ordinary glass with good transparency and durability, in order to improve the durability of the tank body under different temperature conditions, you can also choose tempered glass with higher strength and impact resistance, or sodium borosilicate glass that can withstand high temperature differences and is not easily corroded by chemicals, or aluminum borosilicate glass with better temperature resistance and impact resistance.

[0067] Further, as a preferred embodiment of the present invention but not limitation, the tank body is a non-cylindrical body. Preferably, the tank body is a polygonal prism, and such an arrangement enables the heat exchange tube to be better fixed on the connector when the connector is connected to the surface of the tank body. Specifically, when the tank body is a rectangular parallelepiped, the connector surrounds the front, left, rear, and right four faces of the rectangular parallelepiped in sequence to connect the surface of the sub-rectangle. Since the surface of the rectangular parallelepiped is flat, it can provide more contact points and is relatively matched with the shape of the connector. In this case, the edge of the connector can be completely fitted with the edge of the rectangular parallelepiped, and the coverage area is relatively large. When the tank body is a cylinder, the connector surrounds the outer circumference of the cylinder and is connected to the surface of the cylinder. Due to the curvature of the cylinder, a large seam or gap will be generated between the connector and the cylinder, which will affect the tightness and stability of the connection. Although adhesives can be used to strengthen the bonding, the connection effect may be slightly inferior to that of the rectangular parallelepiped surface. Similarly, since the tank body is a cylinder, the shape formed by the connecting piece continuously surrounding the outer circumference of the tank body is a circle, which means that the heat exchange tube needs to be formed in a circular shape along the outer circumference of the connecting piece. Such a setting makes it impossible for the heat exchange tube to be stably connected to the outer circumference of the connecting piece.

[0068] like Figures 1 to 6 As shown, the implementation method of Example 1 is as follows:

[0069] A heat exchange assembly includes a heat exchange tube 1 and a connector 2 connected to a surface of an object, wherein the heat exchange tube 1 includes a heat exchange tube body 3 located outside the connector 2, a heat exchange tube inlet 4 connected to the heat exchange tube body 3 and for medium to enter, and a heat exchange tube outlet 5 connected to the heat exchange tube body 3 and for medium to discharge, and a first connection layer is provided on one side of the connector 2 facing the heat exchange tube body 3. The heat exchange tube inlet 4 and the heat exchange tube outlet 5 are arranged opposite to each other.

[0070] The utility model arranges a connector 2 on the surface of an object, and the heat exchange tube 1 is connected to the connector 2 through a first connecting layer, so that the space occupied by the heat exchange component can be reduced, and the heat exchange tube 1 will not be shortened due to scale or water quality. At the same time, the connection method between the connector 2 and the heat exchange tube 1 is simple, which can effectively improve the assembly efficiency. The heat exchange tube 1 exchanges heat with the surface of the object through the connector 2, which further increases the heat exchange area and effectively improves the heat exchange efficiency.

[0071] The connector 2 is integrally arranged and continuously formed along the circumference of the object, and its cross section is rectangular. The connector 2 is made of aluminum. The heat exchange tube 1 is made of copper. The first connecting layer is a low-temperature resistant adhesive.

[0072] The heat exchange tube 1 is coiled along the circumference of the connector 2 from top to bottom.

[0073] The heat exchange tube body 3 is provided with a coiling end 31 connected to the connector 2 and a winding end 32, and a plurality of the coiling ends 31 and the winding end 32 are provided, and the winding end 32 is connected between two adjacent coiling ends 31. The coiling end 31 is in a straight line shape, and the winding end 32 is in an arc shape.

[0074] like Figures 7 to 12 As shown, the implementation method of Example 2 is as follows:

[0075] The difference between Example 2 and Example 1 lies in the difference in the connector 2, and the heat exchange tube inlet 4 and the heat exchange tube outlet 5 are located on the same side. Specifically, there are multiple connectors 2, and the multiple connectors 2 are sequentially arranged along the outer circumference of the object. The shape formed by the multiple connectors 2 surrounding the object has a rectangular cross-section, the coiled end 31 is wavy, and the winding end 32 is arc-shaped.

[0076] The multiple connectors 2 are rectangular with uniform specifications. The connectors 2 fit and cover part of the side surface of the container. The connectors 2 form more of an intermediate layer to facilitate the connection of the heat exchange tubes 1 to the connectors 2. This arrangement can save costs and facilitate assembly.

[0077] Example 3

[0078] Example 3, based on Example 2, further has the following implementation mode, specifically, the refrigeration device includes a tank body 6, the tank body 6 is a rectangular parallelepiped, the outer side of the tank body 6 is provided with a heat exchange component as described in Example 2, the side of the connector 2 facing away from the heat exchange tube body 3 is provided with a second connection layer, and the second connection layer is connected between the connector 2 and the tank body 6. The second connection layer is an adhesive.

[0079] Example 4

[0080] The difference between Example 4 and Example 3 lies in the difference between the tank body 6 and the connecting piece 2. Specifically, the tank body 6 is of a special shape, that is, the outer peripheral surface of the tank body 6 is composed of a plurality of side surfaces of different shapes, and the plurality of connecting pieces 2 are of different shapes and can be completely fitted on the side surfaces of the tank body 6 of different sizes and shapes, respectively. The plurality of connecting pieces 2 will fit as closely as possible to further keep the surface of the tank body 6 completely covered by the connecting pieces, thereby reducing heat loss.

[0081] Example 5

[0082] Example 5, based on Example 2, also has the following implementation methods. Specifically, the heat exchange component can be used in a heating device. The heat exchange tube 1 can accelerate the preheating speed. During the movement of the low-temperature medium in the heat exchange tube 1, heat is exchanged with the high-temperature surface of the object, thereby further accelerating the temperature of the medium in the heat exchange tube 1.

[0083] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
