Description

Technical Field

[0001] This application relates to the field of ice and heat storage technology, and in particular to an automatic variable-volume integrated ice and heat storage container device and its variable-volume method. Background Technology

[0002] In the field of ice and heat storage technology, ice and heat storage containers are key equipment. Traditional ice and heat storage containers experience a phase change (water freezing) during operation, causing the medium's volume to expand by approximately 10%, leading to container deformation and potential damage. Therefore, there is an urgent need for a container device and corresponding capacity adjustment method that can automatically adapt to volume changes, improving the safety of ice and heat storage. Summary of the Invention

[0003] To address the problem of traditional ice storage and heat storage systems being unable to integrate, this invention provides an automatic variable-volume integrated ice storage and heat storage container device, comprising:

[0004] Container housings, telescopic bags, and expandable containers;

[0005] The container body is a hollow structure with an opening at the top;

[0006] The telescopic bag is a sealed structure with a preset internal space, filled with antifreeze, and is laid inside the container body, attached to the bottom and side walls of the container body.

[0007] The expandable container has a pre-set space inside, which is connected to the interior of the telescopic bag.

[0008] In one possible implementation, the expandable container is located directly above the telescopic bag.

[0009] In one possible implementation, the expandable container includes: a container shell and a telescopic container package;

[0010] The container shell is hollow inside;

[0011] The telescopic container is disposed inside the container shell and communicates with the telescopic bag, and the telescopic container is a telescopic structure.

[0012] In one possible implementation, the cross-section of the container body is rectangular or circular;

[0013] The telescopic pack includes: a first telescopic pack, a second telescopic pack, a third telescopic pack, a fourth telescopic pack, and a fifth telescopic pack;

[0014] The first, second, third, fourth, and fifth telescopic bags each have a preset space inside, suitable for being filled with antifreeze;

[0015] The first telescopic bag is laid on the bottom wall of the container body and is internally connected to the expansion container;

[0016] The second, third, fourth, and fifth telescopic bags are sequentially laid on the side wall of the container body, and their interiors are connected to the expansion container.

[0017] In one possible implementation, the first, second, third, fourth, and fifth telescopic packets are all sheet-like structures.

[0018] One possible implementation also includes: flexible fiber rope;

[0019] The flexible fiber rope passes through the telescopic bag, fastens it to both sides, and the two ends of the flexible fiber rope are sealed to the telescopic bag, separating the internal space of the telescopic bag.

[0020] In one possible implementation, there are multiple flexible fibers arranged in an array on the telescopic bag.

[0021] One possible implementation also includes: connecting pipes;

[0022] The two ends of the connecting pipe are respectively connected to the telescopic bag and the expansion container.

[0023] One possible implementation also includes: an energy transmission device;

[0024] The energy delivery device is connected to the container body and delivers energy from the container body.

[0025] A variable-capacity method, using the aforementioned automated variable-capacity integrated ice and heat storage container equipment, includes the following steps:

[0026] The interior of the container is filled with tap water.

[0027] The interior of the container is cooled to below zero by an energy transfer device, and the interior of the container is filled with water ice.

[0028] The antifreeze inside the telescopic bag is squeezed into the interior of the expansion container.

[0029] The beneficial effects of the automatic variable-volume integrated ice and heat storage container equipment in this application embodiment are as follows: Automatic volume adjustment is achieved by utilizing the compression and flow of antifreeze within the expansion pack during the phase change of the medium inside the container. When the water inside the container freezes and expands, the expansion pack is compressed, and the antifreeze flows into the expansion container, thereby releasing the expansion force inside the container and preventing container rupture and damage. This improves the safety and reliability of the equipment and achieves integrated ice and heat storage. When the ice inside the container transforms into water due to temperature increase, its volume shrinks, and the antifreeze in the expansion container flows back to the expansion pack under its own gravity. This cycle repeats, and through the squeezing out and reflux of the antifreeze in the compression pack, the automatic variable-volume function is achieved. The container body does not deform due to the phase change of the medium inside the container, ensuring the safety and reliability of the equipment and realizing the integrated ice and heat storage function of the container.

[0041] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0042] like Figures 1-5 As shown, the automatic variable volume ice and heat storage integrated container equipment of this application embodiment includes: a container body 100, a telescopic bag 200, and an expansion container 300. The container body 100 is a hollow structure with an open top. The telescopic bag 200 is a sealed structure with a preset internal space, filled with antifreeze, and the telescopic bag 200 is laid inside the container body 100 and attached to the bottom wall and side wall of the container body 100. The expansion container 300 has a preset internal space and communicates with the interior of the telescopic bag 200.

[0043] In this specific embodiment, the antifreeze in the telescopic pack 200 is squeezed and flows during the phase change of the medium inside the container 100, achieving automatic volume adjustment. When the water inside the container 100 freezes and expands, the telescopic pack 200 is compressed, and the antifreeze flows into the expansion container 300, thereby releasing the pressure inside the container, preventing container rupture, improving the safety and reliability of the equipment, realizing integrated ice and heat storage, and improving space utilization. When the ice inside the container 100 turns into water due to heating, its volume shrinks, and the antifreeze in the expansion container 300 flows back to the telescopic pack by its own gravity. This cycle repeats, and through the squeezing out and reflux of the antifreeze in the compression pack 200, an automatic variable volume function is achieved. The container 100 will not deform due to the phase change of the medium inside the container, ensuring the safety and reliability of the equipment, and realizing the integrated ice and heat storage function of the container 100.

[0044] Specifically, the container body 100 is a hollow structure with an open top. This facilitates filling the container with water and subsequent operations, such as installing an energy transfer device. The container body 100 is sealed by having a lid on top, or by having an expansion container 300 installed on top of the container body 100 for sealing.

[0045] Antifreeze is characterized by its relatively stable volume change under temperature variations and its low freezing point, making it resistant to freezing. During ice storage, when the water inside the container freezes and expands, the antifreeze adapts to the volume change through its own compression and flow. The telescopic pack 200 fits snugly against the bottom and side walls of the container, making full use of the internal space and better integrating with the container structure to achieve automatic volume adjustment.

[0046] When the antifreeze in the telescopic pack 200 changes volume due to the expansion and compression caused by the freezing of water inside the tank, the antifreeze can flow between the telescopic pack 200 and the expansion container 300, thereby balancing the volume change of the entire system and preventing damage to the tank due to excessive internal pressure.

[0047] In one specific embodiment, the expansion container 300 is located directly above the telescopic bag 200, that is, the expansion container 300 and the telescopic bag 200 are arranged vertically, so that when there is liquid inside the expansion container, it can flow into the interior of the telescopic bag 200.

[0048] In this specific embodiment, the antifreeze in the expansion container 300 can flow more smoothly into the telescopic bag 200 under the help of gravity during the flow process, achieving automatic volume change. Specifically, after the tap water in the container body 100 is cooled to below zero by the energy transfer device, it will freeze and increase in volume, squeezing the antifreeze inside the telescopic bag 200. This causes the antifreeze to flow into the expansion container 300 above due to the compression. After the ice melts and releases its energy, its volume decreases. Under the action of gravity, the antifreeze in the expansion container 300 can automatically flow into the telescopic bag 200 below.

[0049] In one specific embodiment, the interior of the expandable telescopic container 300 has a telescopic structure.

[0050] In this specific embodiment, the expansion container 300 is a telescopic structure, capable of flexibly changing its volume according to the inflow or outflow of antifreeze, further enhancing the equipment's adaptability to volume changes. When a large amount of antifreeze flows into the expansion container 300, the interior of the telescopic container 300 can expand to accommodate more antifreeze; when the antifreeze flows back, the interior of the telescopic container 300 can contract to maintain the normal operating state of the equipment, making the entire volume adjustment system more flexible and efficient.

[0051] In another specific embodiment, the volume of the expansion container 300 is larger than the total volume of the antifreeze, which is sufficient to allow all the antifreeze to enter the interior of the expansion container 300.

[0052] In one specific embodiment, the container body 100 is rectangular, wherein the telescopic pack 200 includes: a first telescopic pack 210, a second telescopic pack 220, a third telescopic pack 230, a fourth telescopic pack 240, and a fifth telescopic pack 250. The first telescopic pack 210, the second telescopic pack 220, the third telescopic pack 230, the fourth telescopic pack 240, and the fifth telescopic pack 250 each have a preset space inside, suitable for filling with antifreeze. The first telescopic pack 210 is laid on the bottom wall of the container body 100 and its interior is connected to the expansion container 300. The second telescopic pack 220, the third telescopic pack 230, the fourth telescopic pack 240, and the fifth telescopic pack 250 are laid sequentially on the side walls of the container body 100 and their interiors are connected to the expansion container 300.

[0053] In this specific embodiment, the container body 100 adopts a rectangular structure, which is convenient to manufacture, has good stability, and is easy to combine and install with other equipment. Multiple expansion packs 200 are laid on the bottom and side walls of the container body, enabling comprehensive sensing and adaptation to changes in the internal volume of the container. The expansion packs 200 on the bottom and side walls work together to ensure a more uniform distribution of antifreeze, avoiding localized pressure concentration and improving the stability and ice / heat storage efficiency of the equipment.

[0054] Specifically, the container body 100 adopts a hollow rectangular or circular structure and can hold 0.1-10,000 tons of water. The top opening can be equipped with a sealable cover, or the expansion container 300 can be sealed at the opening. The first telescopic package 210, the second telescopic package 220, the third telescopic package 230, the fourth telescopic package 240, and the fifth telescopic package 250 are respectively attached to the bottom wall and each side wall of the container body 100. In addition, the first telescopic package 210 can cover the inner bottom wall of the container body 100, and the second telescopic package 220, the third telescopic package 230, the fourth telescopic package 240, and the fifth telescopic package 250 can respectively cover each side wall of the container body 100.

[0055] It should be noted that the internal volumes of the first telescopic pack 210, the second telescopic pack 220, the third telescopic pack 230, the fourth telescopic pack 240, the fifth telescopic pack 250, the telescopic container pack 320, and the container box 100 are calculated to ensure that the inner wall of the container box 100 will not be compressed when the container box 100 is filled with water and ice.

[0056] In one specific embodiment, the first telescopic bag 210, the second telescopic bag 220, the third telescopic bag 230, the fourth telescopic bag 240, and the fifth telescopic bag 250 are all sheet-like structures.

[0057] In this specific embodiment, the telescopic pack 200 has a sheet-like structure, which can be tightly attached to the bottom and side walls of the box, minimizing the space occupied by the telescopic pack 200 and improving the utilization rate of the internal space of the box. At the same time, the sheet-like structure of the telescopic pack 200 is easy to manufacture and lay, reducing the production cost of the equipment and improving production efficiency.

[0058] Specifically, when the first telescopic pack 210, the second telescopic pack 220, the third telescopic pack 230, the fourth telescopic pack 240 and the fifth telescopic pack 250 are sealed sheet-like structures with internal space, they are easy to lay and fix on the walls of each groove inside the container body 100.

[0059] In one specific embodiment, it further includes: a flexible fiber rope 500, which passes through the telescopic bag 200, fastens both sides of the telescopic bag 200, and the two ends of the flexible fiber rope 500 are sealed to the telescopic bag 200 to separate the internal space of the telescopic bag 200.

[0060] In this specific embodiment, the flexible fiber rope 500 passes through the telescopic bag 200 and is fastened to both sides, separating the internal space of the telescopic bag 200 and guiding and limiting its deformation. This allows the telescopic bag 200 to deform in a predetermined direction and to a predetermined degree when compressed, preventing damage due to excessive deformation and improving its service life and operational reliability. Simultaneously, the separated internal space allows for more orderly flow of antifreeze within the telescopic bag 200, improving the volume regulation effect.

[0061] Specifically, when the flexible fiber rope 500 passes through the telescopic bag 200, the two sides of the telescopic bag 200 at the passing position adhere to each other, forming a fastening point, which prevents the antifreeze from accumulating downwards due to gravity, greatly improving the stability of the telescopic bag 200 itself.

[0062] In one specific embodiment, there are multiple flexible fiber ropes 500 arranged in an array on the telescopic bag 200.

[0063] In this specific embodiment, multiple flexible fiber ropes 500 are arranged in an array on the telescopic bag 200, which can uniformly apply a fastening force to the telescopic bag 200, further improving the structural strength and stability of the telescopic bag 200. This arrangement avoids the problem of damage or excessive deformation of the telescopic bag 200 in local areas due to uneven force, ensuring that the telescopic bag 200 can maintain a good working condition during long-term use and improving the overall reliability of the equipment.

[0064] Specifically, multiple flexible fiber ropes 500 pass through the telescopic bag 200 at equal intervals in both the horizontal and vertical directions to form an array-like arrangement, evenly distributing the antifreeze inside the telescopic bag 200.

[0065] In one specific embodiment, it further includes: a connecting pipe 400, the two ends of which are respectively connected to the telescopic bag 200 and the expansion container 300.

[0066] In this specific embodiment, the connection pipe 400 ensures that the liquid between the expansion pack 200 and the expansion container 300 can flow smoothly, ensuring the transmission efficiency of antifreeze between the two and avoiding the problem of volume adjustment lag or failure caused by poor connection, making the operation of the entire device more stable and reliable.

[0067] Specifically, each telescopic package 200 is connected to multiple connecting pipes 400.

[0068] In one specific embodiment, the system further includes an energy delivery device connected to the container housing 100, which delivers cold air from inside the container housing 100. The energy delivery device enables efficient utilization of the cold air inside the container housing 100. The cold air generated during ice storage can be delivered to locations requiring refrigeration, such as air conditioning systems and cold storage facilities, through the energy delivery device. This improves the energy efficiency of the equipment, reduces energy waste, expands its application range, and enhances its practicality.

[0069] A variable-capacity method, using the aforementioned automated variable-capacity integrated ice and heat storage container equipment, includes the following steps:

[0070] S100, the interior of the container body 100 is filled with water;

[0071] In this specific step, water is injected into the container 100 through the top opening or pipe until the entire container is filled with tap water. The specific heat capacity of water is approximately 4.2 × 10⁻⁶. 3 J / kg·℃ means that for the same mass of substance, water absorbs or releases more heat when the temperature changes.

[0072] S200, the water inside the container 100 is cooled to below zero by an energy transfer device, causing the water to freeze.

[0073] In this specific step, the water inside the container 100 is cooled to below zero via an energy transfer device according to a certain ratio, causing the water to freeze.

[0074] S300, the antifreeze in the telescopic bag 200 is squeezed into the interior of the expansion container 300;

[0075] In this specific embodiment, during the freezing process of tap water, the water expands as it freezes, exerting a compressive force on the expandable packs 200 laid on the bottom and side walls of the enclosure. Since the expandable packs 200 are sealed structures filled with antifreeze, the antifreeze flows through the connecting pipe 400 into the container pack inside the expansion container 300 after being compressed. The container pack is expandable, expanding as the antifreeze flows in to accommodate more antifreeze, thus balancing the increased volume inside the enclosure due to water freezing and preventing excessive internal pressure. When cold energy needs to be released, the energy transfer device is activated, and a fan transports the cold energy inside the enclosure to the area requiring cooling through the transfer pipe, realizing the utilization of cold energy. During the heat storage process, the volume of the enclosure does not need to change when heat needs to be stored or released.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
