Description

Technical Field

[0001] This application relates to the technical field of mounting brackets for constant temperature systems, and in particular to a support bracket and ventilation structure for radiant heating and cooling coils. Background Technology

[0002] Radiant heating and cooling systems are a comfortable and energy-efficient way to regulate the indoor environment. They provide heat or cooling to the room primarily through radiant heat transfer via pipes embedded in the building structure (such as ceilings, floors, or walls). In this system, the support frame used to support and fix these pipes is a crucial component. It not only needs to reliably fix the coils to reduce their displacement or loosening, but also needs to consider the compatibility of the system's thermal performance with the building structure.

[0003] The structure of commercially available radiant heating and cooling systems includes an insulation layer, a coil layer, and a heat dissipation layer. The insulation layer is located on the side closest to the building. The coil layer typically consists of coil support frames and coils, with the support frames often being simple metal or plastic brackets directly fixed to the insulation layer. The heat dissipation layer is laid on top of the coil layer. Currently, there are two ways to connect the insulation layer to the building: one is the ground type, where the insulation layer is laid directly on the ground; the other is the ceiling type, where the insulation layer is connected to the building ceiling by installing joists or a ceiling frame, and then a decorative layer or plaster layer is installed on the coil layer.

[0004] However, the aforementioned existing technologies have obvious drawbacks. The ground-mounted structure allows the support frame to be directly connected to the ground insulation layer, and the coil is in close contact with the insulation layer. This close contact structure hinders airflow behind the coil, which is not conducive to the exchange of heat between the air and the back of the coil, resulting in energy waste. Although the keel or ceiling frame of the ceiling-mounted structure can form a channel with the building ceiling, this channel is a closed channel, and due to the insulation layer, it still hinders airflow behind the coil. Utility Model Content

[0005] This application provides a radiant heating and cooling coil support frame and ventilation structure, which can at least partially solve the above-mentioned technical problems.

[0006] Firstly, the radiant heating and cooling coil support frame provided in this application adopts the following technical solution: A radiant heating and cooling coil support frame includes: Support plate, one side is used to support the coil; Multiple support members are provided and located on one side of the support plate to connect the entire support frame to the building installation surface and to form a ventilation channel between the support plate and the installation surface. Multiple coiling components are provided and located on the other side of the support plate for fixing and coiling the pipe.

[0007] By adopting the above technical solution, during installation, the support components are first fixed to the building installation surface such as the ceiling or wall. Due to the support of the support components, the support plate and the installation surface are naturally separated, forming a continuous ventilation cavity. Subsequently, the pipes (coils) of the radiant heating and cooling system are coiled and fixed to multiple coiled components on the other side of the support plate according to the design path. The ventilation cavity formed by the support components and the installation surface facilitates air contact with the back of the coil for heat exchange, significantly improving the system's energy efficiency. In the environment where the five constant systems are used, this air flow channel can be used to connect to an external fresh air unit. The existence of the ventilation cavity allows fresh air to pass through, blowing the air with heat or cold in the ventilation cavity into the room, shortening the temperature difference between the fresh air temperature and the indoor temperature, and fundamentally reducing the risk of condensation and mold growth on the walls.

[0008] Optionally, the cross-section of the coiled component is set to be circular.

[0009] By adopting the above technical solution, when the pipe is coiled, the pipe comes into contact with the coiled part with a circular cross-section. The circular cross-section has no sharp corners, and the contact area with the outer wall of the pipe is large and the pressure is small. This can effectively reduce the scratches, wear or flattening of the pipe due to stress concentration during installation or use, extend the service life of the pipe, and at the same time reduce the situation where the flow rate of the flattened pipe is reduced. The smooth surface makes the pipe easier to slide and position during coiling, reducing installation resistance.

[0010] Optionally, the coiled part is in the form of a hollow ring.

[0011] By adopting the above technical solutions, the hollow structure reduces the amount of materials used, lowers production costs and the weight of the entire support frame while ensuring sufficient structural strength, making it easier to transport and install; it also facilitates the filling of concrete or decorative layers, reduces the surface layer thickness, and facilitates heat exchange with the indoor environment.

[0012] Optionally, the support member is spaced apart from the edge of the support plate.

[0013] By adopting the above technical solution, the stress point (the connection of the support component) is moved from the edge to the inside of the plate, which improves the stress distribution of the support plate and enhances the structural stability and durability.

[0014] Optionally, the edge of the support plate is provided with a connector, and a snap-fit ​​groove is formed on the adjacent support plate, the snap-fit ​​groove and the connector being clearance-fitted.

[0015] By adopting the above technical solution, when a large area of ​​coil needs to be laid, the connector of the first support plate can be inserted into the snap-fit ​​groove of the second support plate to complete the rapid splicing of the two plates. This allows individual support frames to be quickly assembled like building blocks, greatly improving the efficiency and installation accuracy of large-area construction. Through the gap fit between the connector and the snap-fit ​​groove, it can be ensured that multiple support plates remain on the same plane after splicing, thereby ensuring the flatness of the coil laying, which is beneficial to the uniformity of radiation effect, and can expand the joint, reducing the warping caused by thermal expansion.

[0016] Optionally, a positioning plate is provided at one end of the support plate where the snap-fit ​​groove is formed, and the positioning plate is disposed on the side wall of the support plate connecting support member.

[0017] By adopting the above technical solution, the positioning plate ensures the alignment of adjacent support plates in the vertical direction (relative to the mounting surface), reducing misalignment or unevenness after splicing; the positioning plate provides an additional contact support surface, which works together with the connector and snap-fit ​​groove to facilitate rough positioning installation, enhance the bending and torsional stiffness of the splicing node, and make the overall integrity better and more stable after multiple support frames are connected.

[0018] Optionally, the coiled component is provided with a plurality of limiting blocks, which are arranged along the circumference of the coiled component and are located on the side of the coiled component away from the support plate.

[0019] By adopting the above technical solution, when the pipe is pressed into the coiled part, the pipe will enter through the gap between the limiting blocks and be blocked by the limiting blocks below, reducing its upward ejection; the limiting blocks form a binding structure, which can effectively reduce the pipe from coming loose from the coiled part even when subjected to accidental external force pulling or system pressure fluctuations causing pulsation, greatly enhancing the reliability of fixation.

[0020] Optionally, the end of the limiting block near the support plate has an arc-shaped chamfer.

[0021] By adopting the above technical solution, the arc-shaped chamfer acts as a guide slope, allowing the pipe to be easily and smoothly inserted into the predetermined position, significantly reducing the installation difficulty and labor intensity; it also reduces the scraping or cutting of the outer wall of the pipe against the sharp edge of the limiting block when the pipe is pressed with force, further protecting the integrity of the pipe; and it increases the binding area of ​​the limiting block on the pipe, resulting in a more balanced force application.

[0022] Optionally, the support member is a support leg, and a reinforcing rib plate is connected between adjacent support legs.

[0023] By adopting the above technical solution, the reinforcing ribs connect the independent support legs into a stable frame structure, which greatly improves the overall rigidity and strength of the support frame when bearing the weight of the coil and pipeline medium, and reduces the deformation or swaying of the support legs; the stable frame structure can better suppress and disperse vibration, further improving the sound insulation and noise reduction effect.

[0024] Secondly, the ventilation structure provided in this application adopts the following technical solution: A ventilation structure includes multiple radiant heating and cooling coil support frames, which are spliced ​​together and installed on a building installation surface to form a ventilation channel with the installation surface. A concrete layer or decorative surface is provided on the side of the radiant heating and cooling coil support frame away from the construction surface, and a ventilation opening connecting to the room is opened on the support plate of any of the radiant heating and cooling coil support frames.

[0025] By adopting the above technical solution, an installation area is planned on the building's roof or wall, and multiple support frames are fixed by their support legs and connected into a whole using their splicing function. The support plates of all these support frames together form an "inner shell" parallel to the building surface, and the space between them and the building surface forms a continuous, large-scale ventilation channel. This spatial expansion and connection creates a powerful air convection channel, thereby greatly enhancing the overall heat insulation, anti-condensation, dehumidification, and heat dissipation effects at the macro level. It is suitable for large venues, factories, and other projects that require large-area radiant heating and cooling, ensuring the safety and dryness of the entire building structure.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The ventilation cavity formed by the support and the mounting surface cuts off the path of the coil directly contacting the building structure through the support plate, effectively reducing the direct conduction of cold / heat to the outside of the wall and significantly improving the system's energy efficiency; In the environment where the five constant systems are used, this air flow channel can be used to connect to the external fresh air unit. The presence of the ventilation cavity allows fresh air to pass through, blowing the air with heat or cold in the ventilation cavity into the room, shortening the temperature difference between the fresh air temperature and the indoor temperature, and fundamentally reducing the risk of condensation and mold on the walls; 2. Through the gap fit between the connector and the snap-fit ​​groove, it can be ensured that multiple support plates remain on the same plane after splicing, thereby ensuring the flatness of the coil laying, which is conducive to the uniformity of radiation effect, and can expand the joint, reducing the warping caused by thermal expansion. 3. The limiting block forms a binding structure, which can effectively reduce the pipe from coming loose from the coiled parts even when subjected to unexpected external force or system pressure fluctuations, greatly enhancing the reliability of the fixation.

Detailed Implementation

[0029] The following combination Figures 1 to 3 This application will be described in further detail.

[0030] refer to Figure 1 and Figure 2 This embodiment provides a radiant heating and cooling coil support frame, the overall structure of which includes a support plate 100, support members 200, and coiling members 300. These components cooperate to form an easy-to-install and fully functional support system. One side of the support plate 100 directly supports the coils of the radiant heating and cooling system and is provided with multiple coiling members 300 for fixing and guiding the pipe routing. The support members 200 are located on the other side of the support plate 100 and are usually fixed to the building installation surface 800 (such as a ceiling or wall) by bolts or nails, maintaining a certain distance between the support plate 100 and the installation surface to form a continuous ventilation cavity. During installation, the support members 200 are first fixed to the building installation surface 800, and then the pipes are coiled around the coiling members 300 according to the designed path, ensuring that the pipes are firmly and evenly distributed.

[0031] In the specific structure, the support plate 100 is typically a plate-shaped component, and its size can be adjusted according to actual engineering needs, such as using a rectangular or square shape to cover a larger area. Multiple support members 200 are provided, evenly distributed on one side of the support plate 100, and the mounting points of the support members 200 are spaced a certain distance from the edge of the support plate 100. This design shifts the stress point from the edge to the interior of the plate, improving the stress distribution of the support plate 100 and enhancing its overall stability and durability. In this embodiment, the support member 200 is a support leg, cylindrical in shape, and its height can be adjusted as needed to control the size of the ventilation cavity and ensure smooth airflow.

[0032] The coiled component 300 is fixed to the other side of the support plate 100 and is usually arranged in an array to coil and fix the pipe; the coiled component 300 can be set as a polygonal, semi-arc or other structure.

[0033] In other embodiments, the cross-section of the coiled part 300 is set to be circular. This smooth shape has a large contact area with the outer wall of the pipe and low pressure, which can effectively reduce the damage or flattening of the pipe due to stress concentration during installation or use, and extend the service life of the pipe. At the same time, the smooth surface facilitates the sliding and positioning of the pipe and reduces installation resistance.

[0034] Furthermore, the coiled part 300 adopts a hollow structure, which reduces the amount of material used, lowers production costs and weight, and facilitates transportation and installation while ensuring sufficient structural strength. At the same time, the hollow design facilitates the filling of subsequent concrete or decorative layers, reduces the surface layer thickness, and optimizes heat exchange with the indoor environment.

[0035] To facilitate large-area construction, the edges of the support plate 100 are equipped with connectors 400, such as protruding latches or plugs. Adjacent support plates 100 have corresponding snap-fit ​​grooves 110. The snap-fit ​​grooves 110 and connectors 400 are fitted with a clearance fit, allowing for a 1mm-2mm gap within the groove. This enables quick and rough positioning and splicing of multiple support plates 100. When laying large-area coils, simply insert the connector 400 of one support plate 100 into the snap-fit ​​groove 110 of another to complete the splicing. This ensures that multiple support plates 100 remain on the same plane, guaranteeing the flatness of the coil laying and promoting uniform radiation. The clearance fit also acts as an expansion joint, reducing the risk of warping due to thermal expansion.

[0036] A positioning plate 500 is also provided at one end of the support plate 100 where the snap-fit ​​groove 110 is opened. The positioning plate 500 is located on the side wall of the support plate 100 connecting support member 200. It is used to align adjacent support plates 100 in the vertical direction, reduce misalignment or unevenness after splicing, and provide additional contact support surface to enhance the bending and torsional stiffness of the splicing node and make the overall structure more stable.

[0037] Multiple limiting blocks 600 are also provided on the coiled component 300. These limiting blocks 600 are evenly distributed around the circumference of the coiled component 300 and are located on the side of the coiled component 300 away from the support plate 100. When the pipe is pressed into the coiled component 300, the limiting blocks 600 form a binding structure, reducing the pipe from popping out or loosening. Even under external pulling force or system pressure fluctuations, the fixing reliability can be ensured. The end of the limiting block 600 near the support plate 100 has an arc-shaped chamfer 610, which acts as a guide ramp, allowing the pipe to be easily and smoothly inserted into the predetermined position, reducing the installation difficulty. At the same time, the arc-shaped chamfer 610 reduces the risk of scratching between the outer wall of the pipe and the edge of the limiting block 600, protecting the integrity of the pipe, and increasing the binding area for more balanced force application.

[0038] refer to Figure 3In addition, a reinforcing rib plate 700 is connected between adjacent support members 200. The reinforcing rib plate 700 connects the independent support members 200 into a stable frame structure, which improves the overall rigidity and strength of the support frame when bearing the weight of the coil and pipeline medium, reduces the deformation or swaying of the support member 200, and further suppresses and disperses vibration, thereby improving the sound insulation and noise reduction effect.

[0039] The working principle of this embodiment is as follows: When using this support frame, firstly, according to the design plan, the support member 200 is fixed to the building installation surface 800, so that the support plate 100 and the installation surface form a ventilation cavity; then, the pipe is coiled on the coiled member 300, and the pipe is fixed by the limiting block 600; for large areas, multiple support plates 100 are spliced ​​by the connector 400 and the snap-fit ​​groove 110 to ensure overall flatness. After installation, the ventilation cavity allows air circulation, removes moisture, reduces cold bridge effect and wall condensation, while the elastic structure of the support frame buffers vibration and reduces noise, and the ventilation channel 810 also promotes moisture dissipation and protects the building structure. The entire system is highly energy efficient, easy to install, and suitable for various radiant heating and cooling scenarios.

[0040] Furthermore, the ventilation cavity formed in this embodiment amplifies the airflow space, slows down the airflow velocity, reduces noise, and prolongs the contact time between the introduced fresh air and the coil, further shortening the temperature difference between the introduced fresh air and the indoor air, reducing the possibility of condensation. Because the airflow space is enlarged, the amount of air introduced into the room by the fresh air unit can be increased without introducing noise, so that the amount of fresh air is sufficient to drive the indoor air to form turbulence, thereby further shortening the indoor temperature fluctuation time, realizing the rapid recovery of the indoor temperature to the set temperature, and improving living comfort; and it also reduces the use of a large number of air ducts, reducing costs.

[0041] This embodiment also provides a ventilation structure based on the radiant heating and cooling coil support frame of Embodiment 1. It includes multiple support frames assembled together, forming a continuous ventilation channel 810 together with the building installation surface 800 (such as the ceiling or wall). Ventilation openings connecting to the interior are provided on the support plate 100 of any of the radiant heating and cooling coil support frames. Overall, the multiple support frames are fixed to the construction surface by their support members 200 and connected into a single unit using splicing functionality. The support plates 100 of all support frames together form an "inner shell" parallel to the construction surface, with a concrete layer or decorative surface typically provided on its upper side for covering and aesthetic purposes. This structure spatially enlarges the ventilation cavity, forming a powerful air convection channel, suitable for large venues, factories, and other projects requiring large-area radiant heating and cooling.

[0042] In practice, the installation area is first planned on the building's roof or wall surface. Multiple radiant heating and cooling coil support frames are then fixed using support members 200. The support members 200 are at the same height to ensure a uniform and continuous ventilation cavity between the support plate 100 and the construction surface. The support frames are joined together using connectors 400 and snap-fit ​​grooves 110 on the edges of the support plates 100: the connector 400 of one support plate 100 is inserted into the snap-fit ​​groove 110 of the adjacent support plate 100, allowing for quick connection using a gap fit. Simultaneously, positioning plates 500 are used for vertical alignment to reduce misalignment. After joining, all support plates 100 form a flat support surface to support the coils, while the space between the support plates 100 and the construction surface forms a large-scale, continuous ventilation channel 810. The coil is fixed to the coiled component 300. The circular cross-section and hollow design of the coiled component 300 facilitate pipe installation and subsequent covering layer construction. The limiting block 600 and the arc-shaped chamfer 610 ensure that the pipe is firmly fixed and easy to install. The reinforcing ribs 700 between adjacent support components 200 further enhance the overall stability and reduce structural deformation.

[0043] When using this ventilation structure, multiple support frames are first spliced ​​and fixed to the construction surface to form a ventilation channel 810, which connects to the interior through air outlets opened on the support plate 100. Then, the duct is coiled, and finally a concrete layer or decorative surface is installed above the support frames. The ventilation channel 810 allows free airflow, carrying away the air within the ventilation channel 810, thus preheating or precooling the incoming fresh air. Furthermore, the ventilation channel reduces the transmission of vibration from inter-floor walls, effectively isolating vibration and noise, ensuring a quiet and comfortable indoor environment. In the five-constant system, the ventilation channel 810 forms a channel for the entry of fresh air. The ventilation channel 810 facilitates heat exchange pretreatment of the introduced fresh air, reducing the temperature difference with the indoor air and lowering the possibility of condensation.

[0044] This design enhances overall insulation, condensation prevention, and dehumidification, making it particularly suitable for large-area applications and ensuring the safety and durability of building structures.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
