DETAILED DESCRIPTION

[0026] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model are described in detail below in combination with the drawings and examples.

[0027] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] In the description of the utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "alignment", "overlap", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features; in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0030] In order to meet the air conditioning demand of heating or cooling without increasing the laying cost, the embodiment provides a kind of Figure 1The multi-channel composite pipe shown comprises a pipe body 1, and is characterized in that it further comprises a central pipe 2 coaxial with the pipe body 1, and a plurality of axially extending arc-shaped partition plates 3 connected between the central pipe 2 and the pipe body 1; the arc-shaped partition plates 3 are uniformly arranged in the circumferential direction. The central pipe 2 and the pipe body 1 realize the transmission of fluids or media of two temperatures, such as the transmission of warm air in the central pipe 2 and the transmission of water or low-temperature gas of a lower temperature in the cavity between the pipe body 1 and the central pipe 2, so that cold air or cold water can be transmitted through the composite pipe for cooling in hot weather, and warm air can be supplied through the central pipe 2 in winter to meet different requirements. The arc-shaped partition plates 3 not only realize the mechanical connection of the central pipe 2 and the pipe body 1, but also further realize the separation of the cavity between the pipe body 1 and the central pipe 2. When the medium is intervened, the medium can be separated and guided, and a plurality of fine vortexes are formed in the transmitted medium, which has the effects of buffering and vortex stirring, is beneficial to the rapid transmission and uniform dissipation of energy, and can avoid the obstruction of bubbles or gas segments to the medium transmission, forms a flow or cutting of the bubbles, and is helpful to the smooth transmission of the medium.

[0031] By Figure 1 It can be seen that the arc-shaped partition plates 3 are at least two groups, each group comprising at least two arc-shaped partition plates; the two groups of arc-shaped partition plates 3 are arranged symmetrically with the pipe body radial as the axis of symmetry, and a first horn-shaped flow guide cavity 4 and a second horn-shaped flow guide cavity 5 which are gradually widened from the radial center and symmetrical (symmetrical about A-A in Figure 1 The two flow guide cavities have a self-center outward guiding function; the first flow guide cavity 6 and the second flow guide cavity 7 are formed in the group, and the flow directions of the two cavities are opposite and converging. The two cavities have a guiding property away from the first horn-shaped flow guide cavity and the second horn-shaped flow guide cavity, and then produce a collision and vortex effect at the critical point, and then shrink under the converging flow guide action of the first flow guide cavity 6 and the second flow guide cavity 7, and are extruded into the cavity, which is beneficial to the rapid transmission of the medium (mainly water or water vapor).

[0032] In order to facilitate the connection with the water supply pipe, the water inlet of the pipe body 1 and the central pipe 2 is provided with a connecting thread; in this way, the water supply pipe is threadedly connected with Figure 2 As shown in the drawings, the water supply pipe comprises Figure 2 An outer pipe 8 and an inner pipe 9 coaxial with the outer pipe 8, and the outer pipe 8 and the inner pipe 9 are connected by at least two connecting rib plates 10 extending in the axial direction and uniformly distributed in the circumferential direction; the water outlets of the outer pipe 8 and the inner pipe 9 are threadedly connected with the pipe body 1 and the central pipe 2 respectively, and of course, other sealing elements such as sealing rings, sealing sleeves, etc. can also be needed, which can be flexibly selected according to actual needs.

[0033] Figure 3 Then a floor heating integrated component containing the aforementioned multi-channel composite pipe is provided, and the laying efficiency can be further improved by the floor heating integrated component without laying one by one, and Figure 3As can be seen, the multi-channel heating pipe is individually assembled inside the radiator pipe 11 (if necessary, heat dissipation fins can be added to the outer wall of the radiator pipe or the pipe wall can be processed into a heat dissipation fin shape to further improve heat exchange efficiency). Multiple insertion slots 12 (see...) are provided on the two oppositely arranged axially extending vertical walls of the radiator pipe 11. Figure 3 ) and multiple insert pieces 13 evenly arranged along the axial direction (see Figure 4 The insertion slot 12 has a recess 14 on each of its opposite inner walls, and the insertion piece 13 has an arc-shaped protrusion 15 on each of its outer walls at both axial ends. The insertion piece 13 has at least one laterally extending notch 16 to provide space for the arc-shaped protrusion 15 when the insertion piece 13 is inserted into or removed from the insertion slot 12, thus allowing the arc-shaped protrusion 15 to insert into or remove from the recess 14, completing the insertion or removal of the insertion piece 13 from the insertion slot 12. Multiple heat dissipation pipes 11 are connected together to form an integrated underfloor heating system. Finally, if further reinforcement of the connection between the heat dissipation fins is required, commonly used clamps can be used.

[0034] It also provides Figure 4 The water supply assembly shown includes a housing 17 and a plurality of water supply pipes 18 installed in parallel within the housing 17. The outlet sections 19 of the water supply pipes 18 are threadedly connected to a multi-channel heating pipe 20 within a radiator pipe 11.

[0035] This water supply fitting allows for individual water supply to each composite pipe in the underfloor heating system, without affecting the others. If one composite pipe is damaged or leaks, that single pipe can be replaced. This is because the underfloor heating systems can be connected sequentially via connecting pipes (with the same structure as water supply pipe 18), making disassembly and assembly flexible and installation convenient.

[0036] It is worth emphasizing that the multi-channel composite pipe, underfloor heating integrated components, and connecting pipes provided in the above embodiments can also be used as a composite pipeline system for inlet and return water pipes. This allows for the continuous supply of hot water, mainly because the hot water in the central pipe and the return water in the cavity between the pipe body and the central pipe can conduct heat to each other, thereby cooling the overheated inlet water and heating the return water, ensuring that hot water at a suitable temperature can always be supplied. At the same time, only one composite pipe needs to be laid, eliminating the need for separate inlet and return water pipes as required by traditional technologies, which greatly reduces the laying cost.
