[0002] With the rapid development of urbanization in my country, people's demand for cooling has increased, especially in the south, where the temperature difference is large, resulting in a rapid increase in the cooling load of buildings, which requires the units to increase the cooling capacity. On the other hand, when the system is in a period of low energy consumption, it is difficult to make rapid adjustments in time to follow the changes in external cooling and heating loads. In addition, the current electricity price tiering policy often has very low electricity prices during the night time when the load is low, and high electricity prices during the day time when the load is high. Therefore, how to solve the contradiction between the supply and demand of cooling and heating has become a key issue that needs to be solved urgently.

[0003] In the prior art, cold storage water tanks are usually used to store cold. However, in order to ensure the cold storage effect, such water tanks have a large overall volume, occupy a large floor space, and have a large overall weight, which leads to the problem of high transportation costs and installation labor costs of traditional water tanks.

[0004] Phase change materials as cold storage media have the advantages of large energy storage per unit volume and high cold storage density. Therefore, there is an urgent need for a device that uses phase change materials as a cold storage medium to solve the above-mentioned "three big and three high" problems of traditional water tanks.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Implementation Method 1

[0032] See also Figures 1 to 4 The utility model discloses an energy storage cold storage pipeline, including a tube body 10, a cold storage structure and a pair of plugs 40; the tube body 10 is a hollow structure; the cold storage structure includes a core rod support 20 and a plurality of phase change cores 30, the core rod support 20 has the same diameter as the inner diameter of the tube body 10, and the core rod support 20 is provided with a plurality of mounting holes 21, the core rod support 20 is arranged in the tube body 10 and abuts against the inner wall of the tube body 10; the phase change cores 30 are respectively inserted into the mounting holes 21 so that the phase change cores 30 are connected to the core rod support 20, and the extension direction of the phase change cores 30 is the same as the axial direction of the tube body 10; the plugs 40 are detachably arranged at both ends of the tube body 10 through threaded connection. It can be understood that threads are provided on the outer walls at both ends of the tube body 10, and threads are also provided on the inner walls of the bucket-shaped plug 40, and the plug 40 is fixed to both ends of the tube body 10 through threaded connection.

[0033] The utility model can more conveniently disassemble the cold storage structure by setting a cold storage structure in the tube body 10 and setting plugs 40 on both sides of the tube body 10, and a single person can quickly complete the installation of the energy storage cold storage pipeline. Secondly, the cold storage structure includes two core rod brackets 20 and several phase change cores 30. The diameter of the phase change core 30 is approximately equal to the diameter of the mounting hole 21. When the phase change core 30 passes through the mounting hole 21, the pressure of the wall of the mounting hole 21 on the phase change core 30 fixes the phase change core 30 on the core rod bracket 20. The diameter of the core rod bracket 20 is equal to the inner diameter of the tube body 10 to ensure that the core rod bracket 20 and the phase change core 30 will not be offset in the tube body 10. The phase change core 30 is made of solid phase change material. Multiple phase change cores 30 can store more cold per unit volume. In actual operation, water is injected into the tube body 10 through the plugs 40 at both ends, and the cold storage effect is achieved through water circulation. When the ambient temperature is low, the cold in the water is transferred to the phase change core 30, and the temperature of the phase change core 30 gradually decreases to achieve the purpose of cold storage; when the ambient temperature rises and the temperature of the water is greater than the phase change core 30, the device begins to feed back the stored cold to the water, and the temperature of the phase change core 30 rises as the water flows through, and the water temperature drops to achieve the purpose of cooling.

[0034] Specifically, in a traditional cold storage water tank, the cold storage capacity of 1 cubic meter of water is 5.85KW / h. By applying phase change materials as the cold storage medium, the cold storage capacity of a 1 cubic meter module composed of multiple energy storage cold storage pipes reaches 82.13KW / h, which can effectively improve the ratio of unit volume and cold storage capacity.

[0035] In a further embodiment, the mounting holes 21 are distributed in a circular shape around the center of the mandrel support 20.

[0036] In a further embodiment, the cross-sectional shape of the phase change core 30 is the same at all locations, and the cross-sectional shape is a centrally symmetrical figure. It is understandable that the cross-sectional shape of the phase change core 30 can be circular, polygonal, or square, and the outer contour line of the cross-sectional shape can be an arc or a straight line so that the phase change core 30 can be stuck in the mounting hole 21. There is no specific limitation on the cross-sectional shape of the phase change core 30.

[0037] like Figure 4 As shown, in a further embodiment, the mandrel holder 20 is further provided with a plurality of pressure relief holes 22, and the pressure relief holes 22 are arranged between the mounting holes 21. The diameter of the mounting hole 21 is 25mm to 35mm, and the diameter of the pressure relief hole 22 is 1mm to 10mm. It can be understood that since the mandrel holder 20 is placed in the tube body 10 perpendicular to the axis of the tube body 10, in order to avoid the mandrel holder 20 hindering the flow of water in the tube body 10 and to avoid the mandrel holder 20 from moving under the action of the water flow, pressure relief holes 22 and pressure relief grooves 23 are provided on the mandrel holder 20, so that the water flow can flow through the pressure relief holes 22 and the pressure relief grooves 23. Specifically, the pressure relief groove 23 is provided on the outer edge of the mandrel holder 20 and extends toward the center of the circle to form an arc-shaped groove to allow water to pass through. It should be noted that, Figure 3 and Figure 4 It can be seen that the size and position of the pressure relief hole 22 can be adjusted according to the situation, so the solution of setting the pressure relief hole 22 at other positions on the core rod support 20 is also within the protection scope of the present application.

[0038] In a further embodiment, the pipe body 10 is made of PE, PVC or PPR. Such a material is both light and heat-insulating, and compared with the metal box of a traditional water tank, it can effectively reduce the weight of the pipe body 10, making it easier to transport and install.

[0039] In a further embodiment, the phase change core 30 is made of one of POM, PA66, PPH, CPVC, and UPVC, and the phase change core 30 can be formed by injection molding, extrusion molding, vacuum forming, or mixed model splicing.

[0040] A further embodiment further comprises a sealing silicone pad, which is disposed between the plug 40 and the tube body 10 to seal the tube body 10 .

[0041] Implementation Method 2

[0042] The second aspect of this embodiment also proposes an energy storage cold storage module, including several energy storage cold storage pipes, mounting blocks and connecting pipelines as described above. The mounting block is provided with matching sockets and slots on the outside. The energy storage cold storage pipes are passed through and fixed in the mounting block. The mounting blocks are connected to each other through the sockets and slots so that all energy storage cold storage pipes are arranged in parallel in the same vertical direction, which effectively reduces the floor space of the energy storage cold storage module and is convenient for users to install and use. The connecting pipeline is connected to the plugs of all the energy storage cold storage pipes. When the water temperature flowing through the energy storage pipe is low, the temperature of the phase change core drops to play an energy storage role. When the ambient temperature rises, the water temperature rises, and the cold stored in the phase change core is released into the water flow. The number of energy storage cold storage pipes is set according to the actual needs of different housing types.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
