Abstract
Description
Technical Field
[0001] This utility model relates to the field of capillary network technology, specifically to a capillary fixing structure for a capillary network. Background Technology
[0002] Capillary networks, as a highly efficient heat exchange terminal device, are widely used in building HVAC, indoor temperature control, and other fields. Their core structure lies in the stable connection between the capillary tubes and the main pipe. The reliability of the fixing structure directly determines the heat exchange efficiency, sealing performance, and service life of the network. Currently, common capillary fixing methods in the industry often employ a single welding point or simple clamps. The former is prone to cracking due to stress concentration at the connection between the main pipe and the capillary tube, while the latter is difficult to adapt to the deformation caused by long-term hot and cold cycles, easily leading to loosening and sealing failure.
[0003] With the expansion of capillary network application scenarios, the demand for multi-capillary array layout is increasing. The existing fixed structure lacks a coordinated reinforcement design for the connection points of adjacent capillary tubes, resulting in insufficient overall structural stability of the array network. During installation and use, uneven stress can easily lead to damage at local connection points, which not only increases maintenance costs but also limits the application and promotion of capillary networks under large-span and high-load conditions. Utility Model Content
[0004] The purpose of this invention is to provide a capillary fixing structure for a capillary network to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a capillary fixing structure for a capillary network, which is disposed on a main pipe for fixing capillary tubes, comprising:
[0006] A welding tab is provided at the connection between the main tube and the capillary tube, the welding tab strengthening the connection between the main tube and the capillary tube;
[0007] The welding pieces are at least two in number and arranged in a linear array;
[0008] A connecting plate is provided on the welding piece, the connecting plate being used to connect two adjacent welding pieces;
[0009] The welded piece is also provided with reinforcing posts, which are used to strengthen the connection between the welded piece and the capillary.
[0010] Preferably, each of the welded pieces is connected to a reinforcing pile.
[0011] Preferably, each of the welding pieces is connected to a first connecting plate and a second connecting plate;

[0016] Preferably, the fixing structure is used to fix the output end, and the welding piece is provided at both ends of the output end.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The capillary fixing structure of this capillary network, through at least two linear arrayed welded plates in conjunction with reinforcing piles, effectively enhances the connection strength at the connection between the main pipe and the capillary, avoiding the cracking or loosening problems that are prone to occur with a single fixing method; the connecting plate enables the coordinated fixing of adjacent welded plates, and the circumferential array arrangement of the first and second connecting plates further disperses stress and improves the overall structural stability of the arrayed capillary. It not only adapts to the array arrangement requirements of multiple capillary tubes, but also adapts to long-term hot and cold cycles and high-load conditions, reducing maintenance costs and extending the service life of the capillary network.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-2This utility model provides a technical solution: a capillary fixing structure for a capillary network, which is disposed on a main pipe 1 for fixing capillary 2. The main pipe 1 and the capillary 2 are connected, and there are at least two capillary 2 arranged in a horizontal array, including:
[0023] A welding piece 3 is provided at the connection between the main tube 1 and the capillary tube 2. The welding piece 3 is used to initially connect the main tube 1 and the capillary tube 2. The connection method between the welding piece 3 and the main tube 1 is welding. It is mainly used to expand the connection area between the capillary tube 2 and the main tube 1, thereby achieving the effect of strengthening the connection between the main tube 1 and the capillary tube 2. The capillary tube 2 includes a connecting end 21 and an output end 22. The connecting end 21 is inserted into the main tube 1 to ensure that the main tube 1 and the capillary tube 2 are connected. The output end 22 is connected to the connecting end 21. A fixing structure is used to fix the output end 22. Welding pieces 3 are provided at both ends of the output end 22. The welding pieces 3 are set on the connecting end 21. The two ends of the output end 22 are respectively provided with the connecting end 21.
[0024] First, the connecting end 21 of the capillary tube 2 is inserted into the main tube 1 to achieve communication between the main tube 1 and the capillary tube 2. Then, the welding piece 3 is connected to the connecting end 21 of the main tube 1 and the capillary tube 2 by welding. The welding piece 3 is used to expand the connection area between the capillary tube 2 and the main tube 1, completing the initial connection between the two and enhancing the connection strength. Since the two ends of the output end 22 of the capillary tube 2 are respectively provided with connecting ends 21, and each connecting end 21 is provided with a welding piece 3, after the welding pieces 3 at both ends are connected to the corresponding main tube 1 by the above welding method, the output end 22 can be stably fixed by the fixed structure, while ensuring the reliability of the communication between the main tube 1 and the capillary tube 2.
[0025] There are at least two welding plates 3 arranged in a linear array. Each welding plate 3 is connected to a reinforcing pile 5. The reinforcing pile 5 is used to stabilize the connection between the capillary tube 2 and the welding plate 3. Together with the connection between the welding plate 3 and the main tube 1, the welding plate 3 and the reinforcing pile 5 effectively strengthen the connection between the main tube 1 and the capillary tube 2. This not only expands the connection area between the main tube 1 and the capillary tube 2, but also provides a first connecting plate 31 and a second connecting plate 32 connected to each welding plate 3. The first connecting plate 31 and the second connecting plate 32 form a cross shape and wrap around the reinforcing pile 5, effectively strengthening the connection between the reinforcing pile 5 and the welding plate 3. The first connecting plate 31 and the second connecting plate 32 are arranged in a circumferential array outside the reinforcing pile 5. The welding plate 3 is also provided with a reinforcing pile 5, which is used to strengthen the connection between the welding plate 3 and the capillary tube 2.
[0026] First, at least two welding plates 3 are connected to the connection end 21 of the main pipe 1 and the capillary tube 2 in a linear array by welding. The welding plates 3 expand the connection area between the two to achieve initial reinforcement. Then, reinforcing piles 5 are connected to each welding plate 3. The reinforcing piles 5 further stabilize the connection between the welding plate 3 and the capillary tube 2, and form a double reinforcement with the welding action between the welding plate 3 and the main pipe 1. At the same time, the first connecting plate 31 and the second connecting plate 32 on each welding plate 3 are wrapped around the outside of the reinforcing pile 5 in a cross shape and arranged in a circumferential array. This structure enhances the connection stability between the reinforcing pile 5 and the welding plate 3, and finally forms a multi-node collaborative reinforcement connection system to achieve a reliable connection between the main pipe 1 and the capillary tube 2.
[0027] A connecting plate 4 is provided on the welding piece 3. The connecting plate 4 is used to connect two adjacent welding pieces 3. The first connecting plate 31 located on two adjacent welding pieces 3 is connected by the connecting plate 4. After the welding of the welding pieces 3 in a linear array, the installation of the reinforcing pile 5, and the cross-wrapping reinforcement of the first connecting plate 31 and the second connecting plate 32 are completed, the first connecting plate 31 on two adjacent welding pieces 3 is connected by the connecting plate 4, so that the dispersed individual welding pieces 3 form a whole structure that is synergistically stressed. The single node stress is transformed into an array-type whole stress, which further improves the structural stability of the welding piece 3 array. Combined with the previous welding reinforcement, reinforcing pile 5 reinforcement and other structures, multi-dimensional synergistic reinforcement of the connection between the main pipe 1 and the capillary tube 2 is achieved, ensuring the reliability of the connection.
[0028] When using the capillary fixing structure of the capillary network, firstly, the connecting ends 21 of at least two capillary tubes 2 arranged in a horizontal array are respectively inserted into the corresponding main tube 1 to achieve communication between the main tube 1 and the capillary tubes 2. Since both ends of the output end 22 of the capillary tubes 2 are provided with connecting ends 21, at least two welding pieces 3 need to be connected between the main tube 1 and the connecting end 21 in a linear array at each connecting end 21 by welding. The welding pieces 3 are used to expand the connection area and complete the initial reinforcement. Then, reinforcing piles 5 are connected to each welding piece 3, and the welding of the welding pieces 3 to the main tube 1 forms a double reinforcement. The connection between the welded plate 3 and the capillary tube 2 is stabilized. At the same time, the first connecting plate 31 and the second connecting plate 32 on each welded plate 3 are arranged in a cross shape around the outside of the reinforcing pile 5 and in a circumferential array to enhance the connection stability between the reinforcing pile 5 and the welded plate 3. Finally, the first connecting plate 31 on two adjacent welded plates 3 are connected by the connecting plate 4, so that the dispersed welded plates 3 form a whole structure that is synergistically stressed, transforming the single-node stress into an array-type whole stress, forming a multi-dimensional synergistic reinforcement system, which not only achieves stable fixation of the output end 22, but also ensures the reliability of the connection between the main pipe 1 and the capillary tube 2.
