Description

Technical Field

[0001] This utility model belongs to the field of capillary network technology, and in particular relates to a capillary network grid structure with good heat absorption effect. Background Technology

[0002] Insulated capillary networks are used in independent heat and humidity control air conditioning systems. Thin and flexible, these capillary networks act as radiant terminals, providing both heating and cooling. When cooling, the system needs to be used in conjunction with a fresh air system. The capillary network has a water distribution structure, characterized by a large heat exchange area, thin walls with good thermal conductivity, uniform heat exchange, and low hydraulic loss. The raw materials for making capillary networks are thermoplastic plastics such as PP-R and PE-RT, which can be thermoformed, are environmentally friendly, and also possess characteristics of high temperature resistance, high pressure resistance, and corrosion resistance.

[0003] Capillary networks are thin, flexible, and lightweight, making them easy to install, allowing for thin covering layers and large installation areas. As such, capillary networks are a highly efficient, ideal, and energy-saving heat exchanger, mainly used for constructing breathing air conditioning walls, capillary network boxes, house heating, and regulating day-night temperature differences in agricultural greenhouses.

[0004] In existing technologies, heat dissipation and absorption of capillaries can only occur through the capillary body itself. However, capillary networks are generally buried in the ground or walls, so their ability to influence ambient temperature needs to be conducted through the walls and ground, which results in poor heat absorption and dissipation effects of capillaries.

[0005] Therefore, we need to design a capillary grid structure with excellent heat absorption to solve these problems. Utility Model Content

[0006] The problem this invention aims to solve is to provide a capillary grid structure with excellent heat absorption effect.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A capillary grid structure with excellent heat absorption includes an inlet pipe and an outlet pipe. A plurality of capillary tubes are arranged between the inlet and outlet pipes, with both ends of each capillary tube connected to the inlet and outlet pipes respectively. Heat-absorbing components are detachably mounted on each capillary tube. Each heat-absorbing component includes an upper clamping plate and a lower clamping plate that are fitted together. Both the upper and lower clamping plates have a plurality of clamping grooves, which are positioned opposite each other and interlocked. The upper clamping plate has an mounting groove and a mounting hole. A heat-conducting element is rotatably mounted in the mounting groove. A push block is slidably mounted on the side wall of the mounting groove, with one end of the push block located in the mounting groove and the other end in the mounting hole. A pressure block is also mounted in the mounting hole, with its side wall slidably fitted to the push block. When the pressure block moves along the mounting hole, it pushes the push block to fit against the heat-conducting element.

[0009] Preferably, there are two mounting slots, which are symmetrically distributed along the mounting hole. Each of the two mounting slots has a plurality of storage slots on its opposite sidewalls, and the plurality of storage slots on the two mounting slots are alternately distributed.

[0010] This configuration, with its two symmetrically distributed mounting slots, provides stable rotation space for the heat-conducting components. The alternating distribution of the storage slots allows for the placement of more heat dissipation columns within a limited space, further increasing the heat dissipation area and improving heat dissipation efficiency. This design makes full use of space, resulting in a more compact structure.

[0011] Preferably, the heat-conducting component includes a rotating shaft and a plurality of heat dissipation columns. The rotating shaft is located in the mounting groove, and both ends of the rotating shaft are rotatably connected to the mounting groove. The plurality of heat dissipation columns are all fixedly connected to the rotating shaft, and the positions of the heat dissipation columns on the same rotating shaft correspond one-to-one with the positions of the storage slots on the mounting groove.

[0012] This design creates a rotatable heat-conducting component by combining the hinge and the heat sink. As the heat sink rotates, it increases the contact interface, enhancing heat conduction. The heat sinks and storage slots are paired one-to-one, allowing them to be stored away when not in use, reducing space requirements and facilitating transportation and storage.

[0013] Preferably, a support block is fixedly provided on the inner wall of the mounting groove, and the position of the support block is opposite to the position of the push block.

[0014] This configuration provides stable support to the push block, ensuring that the push block accurately contacts the heat-conducting component when pushed by the pressure block. This guarantees that heat can be effectively transferred from the heat-conducting component to the push block, and then to other heat dissipation structures, improving the reliability of heat conduction.

[0015] Preferably, both the upper clamping plate and the lower clamping plate are provided with a fixing hole, the fixing hole on the upper clamping plate is located inside the mounting hole and is coaxial with the mounting hole.

[0016] This design facilitates the secure connection between the upper and lower clamping plates. The fixing holes on the upper clamping plate are located within the mounting holes and are coaxial, ensuring accurate positioning of the upper and lower clamping plates during installation and guaranteeing structural stability and assembly accuracy.

[0017] Preferably, the pressure block is frustum-shaped, and its maximum diameter is equal to that of the fixing hole. A countersunk hole is formed on the large-diameter end face of the pressure block, and a through hole is coaxially arranged in the countersunk hole. The diameter of the through hole does not exceed the diameter of the countersunk hole and is equal to the diameter of the fixing hole.

[0018] This design, with its frustum-shaped pressure block, allows for a gradual increase in contact area with the push block as it moves along the mounting hole, thus more effectively pushing the push block into contact with the heat-conducting component. The countersunk and through holes not only reduce the weight of the pressure block but also provide space for the installation of other components, facilitating the installation of fixing bolts, etc.

[0019] Preferably, the upper clamping plate, the lower clamping plate, and the heat-conducting component are all made of aluminum.

[0020] This design leverages the excellent thermal conductivity and low cost of aluminum. The upper and lower clamping plates, as well as the heat-conducting components, are all made of aluminum, enabling rapid heat transfer and improving the overall heat exchange efficiency of the heat-absorbing assembly. Simultaneously, aluminum's relatively light weight reduces the overall weight of the device.

[0021] Preferably, the inner walls of the clamping grooves on both the upper and lower clamping plates are coated with thermal conductive paste.

[0022] This design allows the thermal paste on the inner wall of the clamping groove to fill the tiny gaps between the capillary tube and the clamping groove, reducing thermal resistance and further improving heat transfer efficiency. This enables heat to be transferred more quickly from the capillary tube to the heat-absorbing component, improving the overall system's heat dissipation performance.

[0023] The advantages and positive effects of this utility model are:

[0024] This invention improves upon the traditional capillary network fixing device by using aluminum, which has good thermal conductivity, as the base material. Two interlocking clamps are incorporated to fix the capillary tubes between them, thus securing the capillary network. Thermal paste applied to the clamps enhances the heat transfer efficiency between the capillary tubes and the clamps, improving thermal conductivity. Furthermore, a thermally conductive component on the upper clamp extends from a storage groove on the upper clamp after rotation, increasing the heat exchange area and further improving thermal conductivity.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] Example: Figures 1-4 As shown, a capillary grid structure with good heat absorption effect includes an inlet pipe 1 and an outlet pipe 2. A plurality of capillary tubes 3 are arranged between the inlet pipe 1 and the outlet pipe 2. The two ends of the plurality of capillary tubes 3 are respectively connected to the inlet pipe 1 and the outlet pipe 2 to form a closed circulation channel. Heat absorption components are detachably arranged on the plurality of capillary tubes 3. The heat absorption components are fixed by forming an interference fit with the outer surface of the capillary tubes 3 through a tube clamping groove 17.

[0036] The heat absorption assembly includes an upper clamping plate 4 and a lower clamping plate 5 that are attached to each other. Both the upper clamping plate 4 and the lower clamping plate 5 are provided with several clamping grooves 17. The clamping grooves 17 on the upper clamping plate 4 and the lower clamping plate 5 are positioned opposite each other and are joined together. The diameter of the circular channel formed after joining is consistent with the outer diameter of the capillary tube 3, ensuring the shortest heat conduction path.

[0037] The upper clamping plate 4 is provided with a mounting groove 6 and a mounting hole 15. A heat-conducting component is rotatably mounted in the mounting groove 6. A dovetail groove is formed on the side wall of the mounting groove 6. A push block 14 is slidably mounted on the inner wall of the mounting groove 6. One end of the push block 14 is located in the mounting groove 6, and the other end is located in the mounting hole 15. A pressure block 10 is also provided in the mounting hole 15. The conical surface of the pressure block 10 slides and fits against the inclined surface of the push block 14. When the pressure block 10 moves axially along the mounting hole 15, the axial force is decomposed into a radial force by the inclined surface, pushing the push block 14 to move radially along the dovetail groove and fit against the heat-conducting component. In order to ensure that the pressure block 10 can move within the mounting hole 15, the height of the frustum does not exceed the depth of the mounting hole 15.

[0038] There are two mounting slots 6, which are symmetrically distributed along the mounting hole 15, forming a mirror structure centered on the mounting hole 15. Several storage slots 7 are provided on the opposite sidewalls of the two mounting slots 6, and the storage slots 7 on the two mounting slots 6 are alternately distributed, so that the heat dissipation columns 9 of the heat conduction components on both sides can form an alternating heat dissipation array during rotation.

[0039] The heat-conducting component includes a rotating shaft 8 and several heat dissipation columns 9. The rotating shaft 8 is located within the mounting groove 6, and both ends of the rotating shaft 8 are rotatably connected to the mounting groove 6 via bearings to ensure coaxiality during rotation. All heat dissipation columns 9 are fixedly connected to the rotating shaft 8, and the positions of the heat dissipation columns 9 on the same rotating shaft 8 correspond one-to-one with the positions of the receiving grooves 7 on the mounting groove 6. When a heat dissipation column 9 rotates to the position of the receiving groove 7, a 0.5mm gap is reserved between the outer surface of the heat dissipation column 9 and the inner wall of the receiving groove 7 to avoid interference.

[0040] A support block 13 is fixedly installed on the inner wall of the mounting groove 6. The position of the support block 13 is opposite to that of the push block 14. When the push block 14 is pushed by the pressure block 10, the support block 13 provides a reaction force support for the push block 14, forming a stable force system. Anti-slip teeth are provided on the contact surfaces of the support block 13 and the push block 14 to increase the coefficient of friction and prevent slippage.

[0041] Both the upper clamping plate 4 and the lower clamping plate 5 have through-holes 16. The fixing hole 16 on the upper clamping plate 4 is located inside the mounting hole 15 and is coaxial with the mounting hole 15. The fixing bolt passes through the fixing hole 16 and the through hole 12 and is threaded into the equipment base. When the bolt is tightened, the pressure block 10 moves down synchronously. The inner diameter of the fixing hole 16 is 0.2mm larger than the outer diameter of the bolt to ensure positioning accuracy during installation.

[0042] The pressure block 10 is frustum-shaped, with its maximum diameter transitioning to the inner diameter of the mounting hole 15. A countersunk hole 11 is formed on the large-diameter end face of the pressure block 10, and a through hole 12 is coaxially arranged within the countersunk hole 11. The diameter of the through hole 12 does not exceed the diameter of the countersunk hole 11 and is equal to the diameter of the fixing hole 16. The head of the fixing bolt is recessed into the countersunk hole 11 to ensure the end face of the pressure block 10 is flat. The angle between the generatrix of the conical surface of the pressure block 10 and the axis is preferably 45° to maximize force transmission efficiency.

[0043] The upper clamping plate 4, lower clamping plate 5, and heat-conducting components are all made of 6063 aluminum alloy with a thermal conductivity of not less than 200 W / (m・K). Their surfaces are anodized to form an oxide film with a thickness of not less than 10 μm, improving corrosion resistance. The mating surfaces of the upper clamping plate 4 and lower clamping plate 5 are milled to form a plane with a surface roughness Ra≤1.6 μm, ensuring a bonding rate of not less than 95%.

[0044] The inner walls of the clamping grooves 17 on both the upper clamping plate 4 and the lower clamping plate 5 are coated with thermal grease, preferably silicone grease, with a thermal resistance not exceeding 0.1℃・cm² / W. The coating thickness is controlled between 0.05-0.1mm to fill the microscopic gap between the clamping grooves 17 and the capillary tube 3, thereby reducing the contact thermal resistance.

[0045] The working process of this embodiment is as follows: When in use, first place the lower clamping plate 5 on one side of the capillary tube 3 mesh, and place the upper clamping plate 4 on the other side of the capillary tube 3 mesh, and then fasten them together. When fastening, ensure that the capillary tube 3 is located in the clamping groove 17. Then, rotate the heat-conducting columns on both sides of the mounting hole 15 out of the receiving groove 7 with the rotating shaft 8 as the center. Next, insert the bolt into the through hole 12 from the countersunk hole 11 on the pressure block 10. Then, the bolt will pass through the fixing hole 16 on the upper clamping plate 4 and the lower clamping plate 5 in sequence, and finally be nailed into the surface of the building structure. During this process, the bolt will push the pressure block 10 to move into the mounting hole 15 after being stressed. When the pressure block 10 moves, it will squeeze the push block 14, so that the push block 14 and the support block 13 cooperate with each other to squeeze the rotating shaft 8, preventing the rotating shaft 8 from rotating and causing the heat dissipation column 9 to shift and affect the heat dissipation effect.

[0046] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
