Description

Technical Field

[0001] This utility model relates to the field of indoor heat exchange system technology, specifically a platform that achieves dual-mode heat exchange through perforation. Background Technology

[0002] From north to south, underfloor heating is now quite common. The installation process has remained largely unchanged over the years: leveling the floor, laying insulation boards, laying the heating pipes, and connecting the manifold and return valve – basically the same. As for the heat source, there are many types, including ground source heat pumps, air source heat pumps, municipal heating, and gas-fired boilers, all of which can meet heating needs.

[0003] Underfloor heating systems on the market, whether water-based or electric, all use a single heat exchange mode – radiant heat exchange. Radiant heat exchange is relatively slow, and it usually takes several hours for the heat exchange space to reach the set temperature. Currently, there are no underfloor heating products on the market that use convection heat exchange.

[0004] Patent CN223005074U discloses a dual-mode heat exchange system combining thermal radiation and thermal convection. This system features a dual-pipeline structure, but both pipelines are circular hollow tubes, resulting in only line contact and a small heat transfer area. This leads to low efficiency in transferring energy from the water medium to the transported air, resulting in overall low heat exchange efficiency and unsatisfactory heat exchange effects. Furthermore, the dual-pipeline system is complex to construct and difficult to install. Patent CN222278796U discloses a ventilation system based on a perforated plate structure. This system utilizes a substrate platform to construct the ventilation system, solving the problem of complex end-pipelines and representing a practical solution. Utility Model Content

[0005] The purpose of this invention is to provide a platform for dual-mode heat exchange through perforation, addressing the shortcomings of existing technologies. This is achieved by installing perforation components within a pipe trench and creating perforations in the trench. A water supply pipeline is placed on the upper side of the perforation components, while the lower and periphery of the components are perforated plates. These perforations serve as air supply channels, replacing traditional ducts. The heat or cold energy of the water medium in the water supply pipeline is carried away by the circulating air in the air supply channels and transported to the heat exchange space. By increasing the heat transfer area between the water supply pipeline and the transported air through the perforation components, the platform and the heat exchange space can simultaneously achieve radiative and convective heat exchange, improving overall heat exchange efficiency and solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A platform for dual-mode heat exchange via perforation includes a substrate platform disposed within a heat exchange space. The substrate platform has an upward-facing pipe groove for installing a water supply pipeline. The water supply pipeline is arranged in an S-shape within the heat exchange space, corresponding to the S-shaped pipe groove. The straight section of the pipe groove penetrates the substrate platform axially. The pipe groove is provided with an upward-facing perforation component. The water supply pipeline is installed within the perforation component. After the opening of the pipe groove is sealed by the perforation component, an air supply channel penetrating the substrate platform axially is formed within the pipe groove.

[0007] Furthermore, the perforating element has multiple parts and is respectively arranged in the straight section of the pipe groove. The perforating element penetrates the base plate platform axially. The perforating element has a wire groove at the bending section of the pipe groove. The straight section of the water supply pipeline is installed in the perforating element, and the bending of the water supply pipeline is achieved through the wire groove on the adjacent perforating element.

[0008] Furthermore, the hole-making component includes an upward-facing mounting groove and a connecting plate connected to the opening of the pipe groove, with the water supply pipeline installed inside the mounting groove.

[0009] Furthermore, the mounting groove is a U-shaped structure that matches the water supply pipeline.

[0010] Furthermore, the mounting groove is suspended within the pipe groove.

[0011] Furthermore, the opening of the pipe groove is provided with an interface for suspending the mounting groove within the pipe groove.

[0012] Furthermore, the interface is a flange structure.

[0013] Furthermore, a heat dissipation component is provided on the outside of the mounting slot.

[0014] Furthermore, the heat sink has a U-shaped structure.

[0015] Furthermore, the heat sink has a finned structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention alters the cross-sectional structure of a substrate platform by installing a perforating element within the pipe groove. It transforms an open pipe groove into an installation groove for water pipelines and several perforated air channels, eliminating the need for ductwork and retaining only the water pipeline. This optimizes the pipeline structure and increases the contact area between the water pipeline and the perforating element, expanding the heat transfer area and facilitating heat exchange between the gas in the water pipeline and the air channels. This allows the gas in the air channels to carry away more energy from the water medium in the water pipeline, enabling the substrate platform to simultaneously achieve efficient dual-mode heat exchange—radiation and convection—improving the overall heat exchange efficiency within the heat exchange space. Furthermore, the lower part of the perforating element is a heat sink, which further increases the conduction heat exchange area between the water pipeline and the air in the air channels, allowing the airflow to contact the perforating element as much as possible and carry away more energy. In addition, integrating radiative and convective heat transfer onto the same substrate reduces the additional space required for indoor use. The overall structure is simple and ingenious, making it easy to manufacture, install, and construct, and significantly reducing product costs. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0022] For easier understanding, please refer to Figures 1 to 8 This embodiment provides a platform for dual-mode heat exchange through perforation, including a substrate platform 1 disposed below the ground of the heat exchange space. An S-shaped (serpentine) tube groove 11 with its opening facing upwards is formed on the substrate platform 1. The straight section of the S-shaped tube groove 11 penetrates the substrate platform 1 on both axial sides. A perforation element 2 made of a highly thermally conductive material is overlapped above the tube groove 11; preferably, the perforation element 2 is made of aluminum alloy. The opening of the perforation element 2 faces upwards, and by sealing the opening above the tube groove 11, a perforated air supply channel 6 is formed within the tube groove 11, penetrating both axial sides of the substrate platform 1. A water supply pipeline 3 is S-shaped and tightly fitted within the perforation element 2 above the S-shaped tube groove 11.

[0023] Multiple perforating elements 2 are arranged overlappingly within the straight sections of the pipe groove 11. Each perforating element 2 penetrates the base plate platform 1 on both axial sides. A through-groove 24 is formed at the bend of the pipe groove 11 in each perforating element 2. The width of the through-groove 24 is greater than the total width of the bend of the pipe groove 11, facilitating the installation of the water supply pipeline 3. The straight sections of the water supply pipeline 3 are tightly fitted within the perforating elements 2, and bends are achieved through the through-groove 24 on adjacent perforating elements 2. This allows a single water supply pipeline 3 to be tightly fitted within multiple spaced-apart and side-by-side perforating elements 2 in an S-shaped path, facilitating manufacturing and installation.

[0024] The perforating component 2 includes an upward-facing mounting groove 21 and a connecting plate 22. The water supply pipeline 3 is installed in the mounting groove 21. Specifically, there are two connecting plates 22, extending outward from the horizontal sides of the opening of the mounting groove 21. The mounting groove 21 is connected to the opening of the pipe groove 11 through the connecting plates 22 on both sides. More specifically, the connecting plate 22 is detachably connected to the base plate platform 1. Preferably, the mounting groove 21 has a U-shaped structure that matches the water supply pipeline 3. On the one hand, this allows the water supply pipeline 3 to be tightly fitted and installed in the mounting groove 21. On the other hand, it makes the wall thickness of the perforating component 2 uniform and improves the heat conduction effect, that is, some of the heat of the medium water in the water supply pipeline 3 can be transferred to the continuously flowing gas in the air supply channel 6 more quickly. The mounting groove 21 is suspended within the pipe groove 11 by connecting plates 22 on both sides. That is, the total height of the perforating component 2 is less than the depth of the pipe groove 11. Furthermore, the opening of the pipe groove 11 is provided with an overlapping interface 12. The connecting plates 22 are fitted and installed above the overlapping interface 12. The mounting groove 21 is suspended within the pipe groove 11 through the cooperation of the connecting plates 22 and the overlapping interface. Even though the horizontal sides and lower part of the mounting groove 21 are spaced apart from the pipe groove 11 of the base plate platform 1 to form plate holes, the plate hole areas can all serve as air supply channels 6. A portion of the energy of the medium water in the water supply pipeline 3 can be simultaneously transferred from multiple directions on the horizontal sides and lower part to the continuously flowing gas in the air supply channels 6. Specifically, the overlapping interface 12 is a flange structure protruding into the pipe groove 11, improving the support effect on the perforating component 2. While ensuring that the horizontal sides of the mounting groove 21 are spaced apart from the pipe groove 11, it avoids structural deformation of the perforating component 2 due to downward pressure when installing the water supply pipeline 3. Furthermore, a heat sink 23 is provided on the outside of the mounting slot 21. The heat sink 23 can have various structural forms. In this embodiment, for example... Figure 4 As shown, the heat sink 23 has a U-shaped structure, meaning the perforation component 2 has a double U-shaped structure. The U-shaped mounting groove 21 at the top of the perforation component 2 replaces the pipe groove 11 of the substrate platform 1 as the mounting area for the water supply pipeline 3. The U-shaped heat sink 23 at the bottom of the perforation component 2 combines with the pipe groove 11 of the substrate platform 1 to form two axially penetrating holes in the substrate platform 1, increasing the contact area between the perforation component 2 and the air in the air supply channel 6, further improving the heat conduction effect, and enabling the gas continuously transported in the air supply channel 6 to carry away more heat. Figure 5As shown, the heat sink 23 can also be a finned structure.

[0025] The air supply channel 6 is connected to the air inlet assembly and the heat exchange space on both sides of the base plate platform 1. The air inlet assembly continuously supplies air into the air supply channel 6, and the air is eventually transported to the heat exchange space along the path of the air supply channel 6. Specifically, the air inlet end of the air supply channel 6 is connected to the air inlet assembly, and the air outlet end of the air supply channel 6 is connected to the heat exchange space. The water supply pipeline 3 is connected to the cold and heat source and the circulation pump, and circulates medium water under the ground in the heat exchange space. The cold and heat source contains medium water, and the circulation pump is used to provide power for the water supply pipeline 3 to circulate medium water. When the heat exchange space needs cooling, the water supply pipeline 3 circulates low-temperature cold water; when the heat exchange space needs heating, the water supply pipeline 3 circulates high-temperature hot water. The water supply pipeline 3 is regularly arranged in the heat exchange space according to the spatial structure of the heat exchange space. The cold and heat source, the circulation pump, and the water supply pipeline 3 are connected to form a closed heat radiation loop. Heat is transferred to the air in the heat exchange space through thermal radiation, causing the indoor temperature to rise or fall, ultimately achieving a cooling or heating effect within the space. The temperature of the medium water varies depending on the requirements of the heat exchange space, ranging from 7 to 18 degrees Celsius for the low-temperature state and from 30 to 45 degrees Celsius for the high-temperature state. While the water supply pipeline 3 circulates and transports the medium water, it transfers heat to the air in the heat exchange space through thermal radiation. At the same time, air is continuously supplied to the air inlet end of the air supply channel 6 through the air inlet assembly. Since the water supply pipeline 3 and the perforation component 2 are tightly fitted together, part of the heat in the medium water is transferred downwards and horizontally to both sides through the perforation component 2 to the continuously flowing gas in the air supply channel 6 through thermal radiation. The gas cools down or heats up after receiving the heat transfer and finally enters the heat exchange space from the air outlet end of the air supply channel 6. It transfers heat to the air in the heat exchange space through thermal convection, causing the indoor temperature in the heat exchange space to rise or fall. Another part of the heat in the medium water is transferred to the air in the heat exchange space through thermal radiation, causing the indoor temperature in the heat exchange space to rise or fall. That is, the heat transfer of the air in the heat exchange space is carried out simultaneously through the superposition of thermal radiation and thermal convection, which accelerates the cooling or heating rate of the air in the heat exchange space, shortens the heat exchange time required for the heat exchange space, and improves the user experience.

[0026] The air intake assembly includes an air source distributor 4 and a fan. The air source distributor 4 has a hollow structure with an air source distributor 4 inlet and multiple air source distributor 4 outlets. The fan is connected to the air supply channel 6 through the air source distributor 4. Specifically, the fan is connected to the air source distributor inlet, and the air source distributor 4 outlets are all horizontally oriented towards the air supply end of the air supply channel 6. Furthermore, the air source distributor outlet 41 is parallel and spaced apart from the air supply channel 6, that is, the air source distributor 4 is parallel and spaced apart from one axial side of the substrate platform 1. The air supply channel 6 is connected to the heat exchange space through a gas collector 5. The gas collector 5 has a hollow structure with a long strip-shaped gas collection inlet 51 and multiple arrayed through holes 52. The through holes 52 face into the heat exchange space and are connected to the heat exchange space. Furthermore, the gas collector 5 is parallel and spaced apart from the air supply channel 6, that is, the gas collector 5 is parallel and spaced apart from the other axial side of the substrate platform 1. When the fan is turned on, the pressure difference causes the gas to flow automatically in the same direction. The gas flows sequentially through the gas source distributor 4, the air delivery channel 6, and the gas collector 5 before finally being delivered to the heat exchange space for convection heat exchange. No other direct connection structure is required, simplifying the installation process and reducing installation and manufacturing costs. Furthermore, a valve is installed at the outlet of each gas source distributor 4. The valve is preferably an automatically controllable solenoid valve. The on / off state of the solenoid valve adjusts the gas flow at each outlet to a uniform state, ensuring that the airflow delivered to each air delivery channel 6 is as balanced as possible.

[0027] The air source distributor 4 is parallel to and spaced apart from the axial side of the base plate platform 1. Gas flows out at high pressure through the air source distributor 4. The space serves as a buffer and automatic equalization mechanism, ensuring that the air pressure entering the air inlet of the air supply channel 6 is as even as possible. Similarly, the gas collector 5 is parallel to and spaced apart from the air supply channel 6, buffering and automatically and evenly collecting the air from the outlet of the air supply channel 6 into the gas collector 5, ultimately ensuring that the air blown from each through-hole 52 into the heat exchange space is as even as possible. The spaced area is a necessary testing area before the installation of the air circulation system, a concealed project. Through the space, the air pressure and velocity parameters of the air supply duct are tested, as well as the air balance and velocity at the outlet of the air supply channel 6. These are the basic parameters for control and adjustment after the system is completed. After testing, the spaced area can be directly covered with a metal or plastic plate and fixed with screws.

[0028] In actual construction, the workers first lay a base plate platform 1 with S-shaped pipe grooves 11 in the heat exchange space. Then, a hole-making component 2 is installed on the straight section of each pipe groove 11. After that, the water supply pipeline 3 is installed tightly in the mounting groove 21 of the hole-making component 2 according to the S-shaped path. Then, the water supply pipeline 3 is connected to the cold and heat source and the circulation pump. Then, the air source distributor 4 and the gas collector 5 are fixed on both sides of the axial direction of the base plate platform 1, and the air source distributor 4 and the gas collector 5 are spaced apart from the base plate platform 1. Then, the air source distributor 4 is connected to the fan. After completion, the interval area can be covered with a metal plate or a plastic plate.

[0029] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any changes and modifications made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the scope of protection of the present invention.
