[0024] The utility model will be further described below in combination with the drawings and examples.
[0025] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as generally understood by those skilled in the art to which the utility model belongs.
[0026] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form, and in addition, it should be understood that when the terms "comprise" and / or "include" are used in the specification, there is a feature, step, operation, device, component and / or their combination. It should be noted that the various embodiments in the utility model and the features in the examples can be combined with each other without conflict. The examples will be described in detail below in combination with the drawings.
[0027] Example 1
[0028] In one or more embodiments of the technical solutions disclosed, Figures 2 to 3 As shown in the figure, a phase change module 1, comprising a heat preservation shell, a refrigeration pipeline 1-1 is arranged through the heat preservation shell, the space outside the refrigeration pipeline 1-1 in the heat preservation shell is used for injecting phase change material 1-2, and the refrigeration pipeline 1-1 is used for providing a pipeline for circulating refrigerant flow; The refrigeration pipeline 1-1 is arranged in the heat preservation shell in a bow-shaped bending structure with the head connected to the tail.
[0029] In this embodiment, the structure of the refrigeration pipeline 1-1 is arranged in a bending structure, which can increase the heat exchange area and improve the efficiency of cold storage.
[0030] Optionally, the top of the heat preservation shell is provided with a liquid injection port 1-3, and the phase change material 1-2 can be injected into the cavity of the heat preservation shell through the liquid injection port 1-3; The phase change material 1-2 realizes cold storage and release through the change of state;
[0031] Further, a plurality of first temperature sensors are arranged in the heat preservation shell of the phase change module 1 for detecting the temperature of the phase change material in the phase change module 1.
[0032] Preferably, the positions of the first temperature sensor in the phase change module 1 can be spaced at equal intervals to achieve uniform placement of the first temperature sensor.
[0033] like Figure 3 The figure shown is an exploded view of the thermal insulation shell structure of the phase change module 1. The thermal insulation shell includes a first shell 1-4, a second shell 1-5, a sealing ring 1-6, and a cover plate 1-7. The first shell 1-4 and the second shell 1-5 are nested together. The outer side wall of the second shell 1-5 is adapted to the inner side wall of the first shell 1-4 to achieve a tight fit. The cover plate 1-7 presses the second shell 1-5 into the first shell 1-4 through the sealing ring 1-6.
[0034] Among them, the first shell 1-4 and the second shell 1-5 are quadrilateral shells with single-sided openings;
[0035] Optionally, the thermal insulation shell of phase change module 1 is made of thermal insulation material;
[0036] Optionally, the cooling pipes 1-1 within the phase change module 1 are made of copper or aluminum tubes, which are materials with high heat exchange efficiency.
[0037] In this embodiment, by setting a temperature sensor in the phase change module 1, the cold storage state can be determined, thereby determining whether it is necessary to provide cooling to the phase change module 1 and avoiding energy waste.
[0038] Specifically, the state of cold storage includes complete cold storage and incomplete cold storage; whether cold storage is complete is determined based on the type of phase change material and the temperature.
[0039] For example, if the phase change material is water, the cold storage temperature can be 0℃. If the temperature detected by each temperature sensor reaches 0℃ and remains stable, it indicates that cold storage is complete. If one or more of the first temperature sensors do not reach 0℃, it indicates that cold storage is not complete.
[0040] Example 2
[0041] In one or more of the technical solutions disclosed in the embodiments, such as Figures 1 to 7 As shown, a cold storage device for a communication base station includes: a cooling device, a heat absorption device, and a phase change module 1;
[0042] The refrigeration device and the heat absorption device are respectively connected to the phase change module 1 through valves to realize the cold storage and cold release of the phase change module 1;
[0043] In this embodiment, a phase change module 1 is provided, which can realize cold energy storage, thereby enabling cold storage when there is sufficient power or low electricity price. The stored cold energy can be released when the temperature is high or the electricity price is high, thereby improving the cooling effect and enabling the regulation of energy consumption of communication base stations.
[0044] One possible implementation method, such as Figure 1 As shown, the valves include a first three-way valve, a second three-way valve, a switching valve, and a throttling control valve; the first three-way valve and the second three-way valve are respectively connected to the pipes at both ends of the phase change module 1, and the first three-way valve and the second three-way valve are respectively connected to the refrigeration device and the heat absorption device delivery pipes to form a cold storage pipe and a cold release pipe; a switching valve is provided on the pipe connecting the second three-way valve and the phase change module 1, and a throttling control valve is provided on the pipe connecting the second three-way valve and the heat absorption device;
[0045] Further technical solutions include manual control of the valves or electric control via a control module, and control of the start-up and shutdown of the refrigeration and heat absorption devices via the control module. Existing technologies can be used to determine the specific control methods.
[0046] It should be noted that in the above scheme, setting up phase change module 1 can realize the use of cold storage when needed, and the flexibility of energy use regulation can be realized by setting up phase change module 1; among them, the control method of using phase change module to store cold when the electricity price is low or the electricity supply is sufficient is the existing technology, and this embodiment does not improve or limit it.
[0047] Specifically, such as Figure 1 As shown, the left-side pipeline is the cold storage pipeline. When the first three-way valve and the second three-way valve are respectively connected to the left side of the diagram, the two ends of the refrigeration device are connected to the phase change module 1, and can store cold for the phase change module 1 through the refrigeration cycle; the two ends of the heat absorption device are connected to the phase change module 1, and can release cold for the phase change module 1 through the heat absorption cycle.
[0048] One feasible and specific configuration is that the cooling device is located outside the cabinet body, the heat absorption device is located inside the cabinet body, and the phase change module 1 is arranged on the inner side wall of the cabinet body.
[0049] The cabinet body is the cabinet in which the cold storage device of this embodiment is installed. In this embodiment, it can be the cabinet of a communication base station.
[0050] In some embodiments, multiple phase change modules 1 can be provided. Multiple phase change modules 1 are connected through external pipes 5 to form a parallel connection structure. They can be connected to the refrigeration device and the heat absorption device through valves respectively. The operation of other phase change modules 1 will not be affected after each phase change module 1 is cut off individually.
[0051] Furthermore, another feasible technical solution is to configure multiple phase change modules 1 in a series connection structure, and to set a controllable bypass pipe for each phase change module 1, so that when the corresponding phase change module 1 is cut off, bypass can be achieved through the bypass pipe.
[0052] In the above scheme, each phase change module 1 is connected in series through pipes to form a loop. This setting facilitates the delay of cold storage time and makes the cold release effect better. Each phase change module 1 is connected in series to form a cold storage and cold release loop.
[0053] In this embodiment, cold storage refers to the process of storing cold energy, and cold release refers to the process of releasing the stored cold energy.
[0054] Optionally, the heat-insulating shell of the phase change module 1 is made of heat-insulating material, and the cabinet of the communication base station cabinet is also made of heat-insulating material; through the double-layer heat insulation of the heat-insulating shell and the cabinet, the cold energy is delayed from dissipating to the outside of the cabinet.
[0055] In some embodiments, the heat absorption device is an evaporator 2, which is installed inside the communication base station cabinet. One end of the evaporator 2 is connected to one end of the pipe in the phase change module 1 through a first three-way valve, and the other end of the evaporator 2 is connected to the other end of the pipe in the phase change module 1 through a throttling control valve, a second three-way valve, and a switching valve.
[0056] In some embodiments, the control module may be a microcontroller or a PLC controller.
[0057] Furthermore, it also includes a second temperature sensor, which is located inside the cabinet body and is communicatively connected to the control module; the second temperature sensor transmits the collected temperature to the control module.
[0058] In the above scheme, when the first temperature sensor detects that the temperature inside the cabinet exceeds the preset value, the control module controls the throttling control valve to open and the throttling control valve to work. At this time, the main controller controls the throttling control valve according to different temperatures to adjust the refrigerant flow through the evaporator 2. The evaporator 2 evaporates the cold energy absorbed by the refrigerant into the interior of the cabinet body to cool the equipment inside the cabinet.
[0059] In some embodiments, the refrigeration device includes a compressor 3 and a condenser 4; the compressor 3 and the condenser 4 are installed outside the cabinet, one end of the compressor 3 is connected to the refrigeration pipe 1-1 in the phase change module 1, and the other end is connected to the condenser 4 through an external pipe 5, and the other end of the condenser is connected to the phase change module 1.
[0060] In the above scheme, when in use, the compressor 3 in the refrigeration device compresses the low-temperature, low-pressure gas into a high-temperature, high-pressure gas. After the high-temperature, high-pressure gas discharged by the compressor 3 enters the condenser 4, it absorbs the cold energy from the outside, thereby condensing the high-temperature, high-pressure gas into a low-temperature, high-pressure liquid. After the liquid in the condenser 4 enters the phase change module 1, the temperature in the phase change module 1 is reduced, thus realizing the storage of cold energy.
[0061] like Figures 3 to 5 The diagram shows the structure of the communication cabinet. The phase change module 1 is installed on the inner wall of the cabinet. Each phase change module 1 has a certain cooling capacity. The number of phase change modules 1 required for each cabinet is configured according to the cooling requirements of the cabinet. Multiple phase change modules 1 are connected through an interface.
[0062] In one specific example, to accommodate the internal components of the cabinet, the cabinet is configured with a frame structure, including a mounting frame 6 and a mounting bracket 7. The mounting bracket 7 can be located on the sides and rear of the cabinet. The mounting frame 6 provides mounting space for the phase change module 1, and the mounting frame 6 and the phase change module 1 can be fixed together with bolts.
[0063] The top of the cabinet is equipped with a mounting box, which contains a condenser 4 and a compressor 3. The side wall of the mounting box has several ventilation holes for heat dissipation. The bottom of the mounting box is equipped with an evaporator, and the corresponding pipes are equipped with on / off valves and throttling control valves.
[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
[0065] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
