Description

Technical Field

[0001] The present application relates to a heat exchange component and a heat exchange system, which are suitable for heat exchange in different environments. Background Art

[0002] In the prior art, one way to exchange heat in different environments, such as indoors and outdoors, is to install floor heating, by burying heat exchange tubes in the floor or wall of a building, and using on-site pouring or laying methods during construction. The disadvantage of this method is that it requires on-site construction, especially on-site concrete pouring, which requires curing time, resulting in a longer construction period and inability to achieve rapid construction. On the other hand, the heat exchange tubes in the prior art are usually large in diameter, but such large-diameter tubes have a smaller specific surface area, resulting in poor heat dissipation efficiency. Therefore, either the number or length of the heat exchange tubes needs to be increased, or fins need to be added to the outside of the heat exchange tubes, which will undoubtedly lead to increased costs and increased construction complexity.

[0003] Therefore, there is a need in the prior art for a heat exchange assembly that can meet the heat exchange requirements while maximizing the speed of construction and reducing the number of heat exchange tubes. Utility Model Content

[0004] This application provides a heat exchange assembly and heat exchange system. By installing heat exchange tubes within the heat exchange assembly, heat from the tubes can be transferred to the panel, thereby forming a large heat exchange surface, improving heat exchange efficiency and reducing the number of heat exchange tubes. Furthermore, the heat exchange assembly can be modularized, allowing for prefabrication and on-site assembly, thereby improving construction efficiency.

[0005] The present application relates to a heat exchange assembly, comprising a shell and a heat exchange tube that conduct heat to each other. A positioning structure is provided inside or on the shell, and the heat exchange tube is arranged inside or on the shell through the positioning structure.

[0006] In which, the interior of the shell may also be provided with energy storage material; the positioning structure may be integrally formed with the shell, or the positioning structure and the shell may be formed separately; the positioning structure may be a mounting hole or a slot structure or a close-fitting structure; reinforcing ribs may be arranged at intervals in the internal cavity of the shell; the exterior of the shell may also be provided with a thermal isolation structure, which may include a cavity structure arranged on the outer surface of the shell; the interior of the shell may also be provided with a pipe rack for supporting and positioning the heat exchange tubes so that the heat exchange tubes are in close contact with the shell; the heat exchange tubes may be arranged in sections in the positioning structure of the shell, and the heat exchange tubes may be connected by connectors.

[0007] The present application also relates to a heat exchange system, comprising the heat exchange assembly as described above.

[0008] The heat exchange assembly and heat exchange system according to this application have the following technical advantages:

[0009] (1) The heat exchange assembly of the present application can realize modular prefabrication and on-site module assembly, which can not only improve production efficiency but also greatly improve on-site installation efficiency;

[0010] (2) The present application provides a shell and a heat exchange tube that can conduct heat to each other, and arranges the heat exchange tube inside or on the shell through a positioning structure, so that efficient heat transfer can be achieved between the shell and the heat exchange tube. This not only solves the assembly and positioning problems of the heat exchange tube, but also allows the heat in the heat exchange tube to be quickly released through the shell;

[0011] (3) By filling the shell of the heat exchange component with energy storage material, the present application not only improves its strength so that it can be used as a ground heat exchange plate, a ground decorative plate or other load-bearing plate, but also allows it to operate and store heat during off-peak periods, thereby reducing the economic cost of operation during peak periods and saving expenses.

[0022] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0023] like Figure 1 As shown, a heat exchange component according to the present application is shown, including a shell 1, at least one cavity is provided inside the shell 1, and a plurality of heat exchange tubes are also provided inside the shell 1. The heat exchange component of the present application is preferably made into a modular structure, for example, it can be in the form of a heat exchange plate. The heat exchange components are interconnected by connecting parts to form a whole, for example, they can be seamlessly spliced ​​with each other in the form of heat exchange plates to form a wall or floor or decorative panel. The heat exchange tubes 2 on the heat exchange component can be connected in series, in parallel, or a combination of the two. In order to make the heat exchange component have an energy storage function, energy storage material 4 can be filled in the cavity, such as Figure 1 shown.

[0024] The shell 1 of the heat exchange component is made of a material with good heat dissipation performance, which can be plastic or metal. It is preferred to use commonly used aluminum alloy profiles, which are not only high in strength but also have good heat dissipation performance. The heat exchange tubes can be attached to or embedded in the shell 1. Figure 2-3 In the embodiment shown in FIG6, the housing 1 may be provided with a positioning structure 11 for arranging the heat exchange tube. The positioning structure 11 may be as follows: Figure 2 Mounting holes shown in or Figure 3 The slot structure described in the above may also be as follows Figure 6 The close-contact structure shown in the figure is a close-contact structure. The positioning structure forms good and close contact with the heat exchange tube 2 so as to transfer the heat in the heat exchange tube 2 to the shell 1. As needed, the heat exchange tube 2 can be arranged on one side or both sides of the shell 1. Reinforcement ribs 12 are arranged at intervals in the cavity of the shell 1, so that the entire shell has strength and rigidity, and can also divide the cavity into a plurality of independent sub-cavities. The positioning structure 11 on the shell 1 can be integrally formed with the reinforcement rib 12, or it can be a split structure. In an alternative embodiment, no positioning structure may be provided, but the heat exchange tube 2 may be positioned inside the shell 1 by the energy storage material 4. In this case, the structure will be simpler, and the heat exchange tube 2 only needs to be arranged inside the shell together with the energy storage material 4.

[0025] like Figure 4 As shown, in the case of single-sided heat exchange of the heat exchange tube, a thermal isolation structure may be provided to prevent heat loss caused by heat conduction to the non-exposed surface through the reinforcing ribs 12 on the shell 1. Figure 4The illustrated thermal isolation structure includes a cavity structure 14 disposed on the outer surface of the housing 1. This cavity structure 14 enhances thermal insulation performance. Furthermore, the cavity structure 14 can be sealed, and a vacuum can be created within the cavity structure 14 to further enhance the thermal insulation effect. Preferably, the reinforcing ribs 15 of the cavity structure 14 are staggered from the reinforcing ribs 12 of the housing 1. By increasing the distance between the reinforcing ribs 15, the number of ribs 15 can be reduced while preventing heat loss through conduction.

[0026] like Figure 5 As shown, in one embodiment, the heat exchange tubes 2 can be arranged in sections within the positioning structure of the housing 1. The heat exchange tubes 1 are then connected together via connectors 21 to form a door-sealed heat exchange pipeline, with the heat exchange medium flowing into and out of the pipeline at its ends, respectively. Alternatively, the connectors 21 may be omitted, and the heat exchange tubes 2 can be directly assembled and fixed to the housing 1, which can improve production efficiency and enhance the sealing reliability of the heat exchange pipeline.

[0027] like Figure 6 As shown, a pipe rack 22 can be added to support and position the heat exchange tube 2, so that the heat exchange tube 2 and the shell 1 are in close contact to form good heat conduction. In order to reduce the gap between the heat exchange tube 2 and the positioning structure 11 and increase the heat transfer resistance, a thermal conductive adhesive, such as thermal conductive polyester, can be applied to the heat exchange tube 2 to reduce the heat transfer resistance. Figure 7 As shown, in order to facilitate the splicing of the heat exchange plates and integrate them with the building structure, preferably, the length of the heat exchange tube 2 does not exceed the size range of the shell 1. The positioning structure 11 on the shell 1 can be partially removed at the end of the shell to free up the preset space structure of the heat exchange tube 2, so that the heat exchange tube 2 is completely preset within the range of the shell. Figure 10 As shown, the energy storage material 4 can also be directly made into the shape of the tube rack 22, and the shape of the energy storage material 4 can be directly used to expand and position the heat exchange tube 2, or the heat exchange tube 2 can be in close contact with the shell.

[0028] Preferably, the heat exchange assembly of the present application can be made into a decorative plate, and multiple decorative plates can be spliced ​​together by the joint 3. Figure 8 As shown, the joint 3 can be designed with an assembly structure that fits with the shell 1, and the joint 3 is further fixed to the wall by metal nails. In order to further save the cost of use, the decorative plate can be made to have an energy storage function, such as Figure 9 As shown, energy storage material 4 can be filled into the cavity of the housing 1. By operating during off-peak hours, the energy released by the heat exchange tube 2 is stored in the energy storage material 4. During peak hours, the energy storage material 4 releases the stored energy, reducing the heat exchange time of the heat exchange medium during peak hours, thereby achieving energy efficiency.

[0029] The present application also relates to a heat exchange system, including the heat exchange assembly described above. The present application does not improve any part other than the heat exchange assembly, so the existing technology can be used and will not be described in detail.

[0030] The heat exchange medium of the present application can be hot water or cold water to achieve heating and cooling within the building; it can also be low-pressure or medium-pressure steam. The heat exchange medium can also be a refrigerant, and the heat exchange pipes are further connected to an air source heat exchange unit, which realizes heat exchange between the inside and outside of the space through the air source unit. For example, when the building needs to be heated, the decorative panels installed on the outside of the building can exchange heat with the air outside the building, absorb the heat from the air outside the building, and transfer it to the decorative panels inside the building through the unit. They then exchange heat with the air inside the building to provide heat, making the building warmer. When the building needs to be cooled, the decorative panels installed on the outside of the building can exchange heat with the air outside the building, absorb the coldness from the air outside the building, and transfer it to the decorative panels inside the building through the unit. They then exchange heat with the air inside the building to provide coldness, making the building cooler. The heat exchange component of the present application can be laid on the wall, floor or ceiling, and can bear weight or be stepped on within the building. A protective layer can also be laid on the heat exchange component to increase its service life.
