[0033] In related technologies, existing energy storage and release systems involve setting up energy storage stations, energy storage stations, and energy consumption stations. During periods of low electricity prices, the system stores cold energy and stores energy through the energy storage stations. Then, during periods of higher electricity prices, the energy consumption stations release the energy. However, because the energy storage stations are connected to the energy storage stations and energy consumption stations via pipelines, they are inconvenient for users to carry and use outdoors.

[0034] Reference Figures 1 to 5The energy storage and release system according to the embodiment of the utility model, including energy storage station 100, energy consumption station 300 and energy storage station 200, energy storage station 100 is equipped with cold storage cavity 101, energy consumption station 300 is equipped with energy consumption cavity 301, energy storage station 200 is equipped with energy storage liquid, energy storage station 200 is detachably installed in cold storage cavity 101, or, energy storage station 200 is detachably installed in energy consumption cavity 301, so that energy storage and release system has energy storage state and energy release state, wherein, energy storage and release system is in energy storage state, energy storage station 200 is installed in cold storage cavity 101, and energy storage station 100 can cool energy storage liquid, and energy storage and release system is in energy release state, energy storage station 200 is installed in energy consumption cavity 301, and energy consumption station 300 can take the cold energy of energy consumption station 300, so that the traditional technical scheme that energy storage station 200 is connected between energy storage station 100 and energy consumption station 300 can be abandoned, energy storage station 200 can be taken out or installed alone, which is convenient for user to carry and transport and is convenient for user to use outdoors.

[0035] For example, in the time period of low electricity cost, the user can install the energy storage station 200 in the cold storage cavity 101, so that the energy storage station 100 cools the energy storage liquid in the energy storage station 200; when used outdoors, the user can take out the energy storage liquid from the cold storage cavity 101 and install the energy storage station 200 in the energy consumption cavity 301, so that the energy consumption station 300 can take the cold energy of the energy storage station 200. By adopting the detachable installation of the energy storage station 200, the energy storage and release system can be switched between the energy storage state and the energy release state, the traditional technical scheme that the energy storage station 200 is connected between the energy storage station 100 and the energy consumption station 300 can be abandoned, the energy storage station 200 can be taken out or installed alone, which is convenient for user to carry and transport and is convenient for user to use outdoors.

[0036] In some embodiments of the utility model, energy storage station 100 includes first shell 110, compressor 120, condenser 130 and evaporator 140, evaporator 140, compressor 120 and condenser 130 are sequentially connected, first shell 110 is equipped with the heat dissipation cavity 102 and cold storage cavity 101 of separate arrangement, compressor 120 and condenser 130 are located in heat dissipation cavity 102, and at least part of evaporator 140 is located in cold storage cavity 101, when energy storage and release system is in energy storage state, evaporator 140 cools energy storage liquid. After the start of compressor 120, the refrigerant circulates between evaporator 140, compressor 120 and condenser 130, and the refrigerant exchanges heat with the energy storage liquid in the cold storage cavity 101 through the evaporator 140, so that the temperature of the energy storage liquid is lowered, and the effect of energy transfer of the energy storage liquid is indirectly achieved, so that the refrigerant can drive the cold energy into the energy storage station 200 for storage.

[0037] It should be noted that the evaporator 140, the compressor 120 and the condenser 130 are connected in series through copper pipes to form a refrigeration circuit, and the refrigerant flows in the refrigeration circuit to make the evaporator 140 absorb heat and the condenser 130 generate heat, which will not be described in detail here.

[0038] In some embodiments of the utility model, the energy storage station 100 further comprises a first door body rotatably connected to the first shell 110, the cold storage cavity 101 has a first opening 103, and the first door body is used for opening or closing the first opening 103, and the energy storage station 200 is installed in or taken out of the cold storage cavity 101 through the first opening 103, which can facilitate the taking out or installation of the energy storage station 200.

[0039] For example, when the energy storage and release system switches from the energy release state to the energy storage state, the first door body is rotated to open the first opening 103, the energy storage station 200 can be installed in the cold storage cavity 101 through the first opening 103, the first door body is driven to close the first opening 103, so that the energy storage station 200 stores energy in the cold storage cavity 101, after the energy storage station 200 finishes storing energy, the first opening 103 is reopened to take out the energy storage station 200 from the cold storage cavity 101 and install the energy storage station 200 in the energy consumption cavity 301, so that the energy storage and release system switches from the energy storage state to the energy release state, and the first door body can facilitate the taking out or installation of the energy storage station 200.

[0040] As another implementation, the first door body can also be replaced by a drawer, and the drawer is slidably arranged in the cold storage cavity 101 through the first opening 103, which can also facilitate the taking out or installation of the energy storage station 200, which is not limited here.

[0041] In some embodiments of the utility model, the energy consumption station 300 has an energy consumption end, and when the energy storage and release system is in the energy release state, the cold energy of the energy storage liquid is taken by the energy consumption end, which can facilitate the energy consumption station 300 to take the cold energy of the energy storage liquid.

[0042] For example, the energy consumption end is provided with a connecting joint, and the energy storage liquid in the energy storage station 200 enters the energy consumption end through the connecting joint, which can facilitate the energy consumption station 300 to take the cold energy of the energy storage liquid.

[0043] In some embodiments of the utility model, the energy storage station 200 is detachably connected with the energy consumption end, which can facilitate the installation or disassembly of the energy storage station 200.

[0044] For example, the energy storage station 200 is connected with the energy consumption end through a threaded cooperation mode, for example, the energy storage station 200 is provided with a liquid outlet joint, the energy consumption end is provided with a connecting joint, the liquid outlet joint is provided with an external thread, the connecting joint is provided with an internal thread, the external thread and the internal thread are threadedly cooperated, which is simple, convenient and fast, and can facilitate the installation or disassembly of the energy storage station 200.

[0045] With reference to Figure 5 In some embodiments of the present application, the energy consumption station 300 includes a second housing 310, a heat sink 320, and a blowing device 330. The energy consumption cavity 301 is located in the second housing 310, and the heat sink 320 and the blowing device 330 are both arranged in the second housing 310. The blowing device 330 is provided with an energy consumption end. The energy storage station 200 is connected to the heat sink 320, thereby realizing the process of cold energy release of the energy storage liquid in the energy release state through the heat sink 320. For example, when the energy storage and release system is in the energy release state, the energy storage liquid in the energy storage station 200 flows into the heat sink 320, and the blowing device 330 releases cold energy through the heat sink 320, thereby realizing the effective utilization of cold energy.

[0046] It can be understood that by designing the energy consumption station 300 including the heat sink 320 and the blowing device 330, when the energy storage and release system is in the energy release state, the energy storage station 200 is connected to the heat sink 320 through the pipeline, and the blowing device 330 is used to effectively release cold energy, which is convenient for carrying and outdoor use, so that the user can more flexibly utilize the cold energy of the energy storage and release system, and is especially suitable for scenes requiring portability and outdoor use.

[0047] In some embodiments of the present application, the energy storage station 200 includes a water tank and a liquid storage pipe. The liquid storage pipe is in communication with the inside of the water tank. When the energy storage and release system is in the energy release state, the liquid storage pipe is connected to the energy consumption end, and the energy storage liquid in the water tank flows to the energy consumption end through the liquid storage pipe.

[0048] It can be understood that the water tank of the energy storage station 200 is used to store the energy storage liquid, and the liquid storage pipe is used to connect the water tank and the pipeline. When the system is in the energy release state, the energy storage liquid flows into the pipeline through the liquid storage pipe, and then is supplied to the energy consumption station 300 for use, so that the transportation of the energy storage liquid is more efficient and convenient.

[0049] It should be noted that the water tank of the energy storage station 200 can be made of various materials, such as stainless steel, aluminum alloy, or other corrosion-resistant materials, to ensure the safe storage of the energy storage liquid. The liquid storage pipe can be designed as a flexible pipe or a rigid pipe, which is selected according to the specific application environment. In addition, the connection mode of the liquid storage pipe can be a quick connector or a threaded connection, so as to facilitate installation and disassembly.

[0050] It should be noted that the energy storage station 200 can be flexibly switched in different states, which is convenient for users to use the energy storage and release system in different scenes, improves the portability and use convenience of the energy storage system, and is especially suitable for energy management requirements in outdoor or mobile scenes.

[0051] In some embodiments of this utility model, the energy consumption station 300 further includes a second door body rotatably connected to the second housing 310. The energy consumption cavity 301 has a second opening 302. The second door body is used to open or close the second opening 302. The energy storage station 200 is installed in or taken out of the energy consumption cavity 301 through the second opening 302. The energy storage station 200 is installed in or taken out of the energy consumption cavity 301 through the second opening 302, which facilitates the removal or installation of the energy storage station 200.

[0052] For example, when the energy storage and release system switches from the energy storage state to the energy release state, the second door is rotated to open the second opening 302. The energy storage station 200 can be installed in the energy consumption chamber 301 through the second opening 302. The second door is then driven to close the second opening 302 so that the energy storage station 200 consumes energy in the energy consumption chamber 301. After the energy storage station 200 has finished consuming energy, the second opening 302 is reopened so that the energy storage station 200 can be taken out from the energy consumption chamber 301 and installed in the cold storage chamber 101, thus switching the energy storage and release system from the energy release state to the energy storage state. By setting the second door, it is easy to take out or install the energy storage station 200.

[0053] As another implementation, the second door can also be replaced by a drawer, which is slidably disposed in the energy dissipation cavity 301 through the second opening 302, and can also facilitate the removal or installation of the energy storage station 200, without limitation.

[0054] In some embodiments of this utility model, multiple energy-consuming chambers 301 are configured, arranged in an array with intervals, and correspondingly spaced cold storage chambers 101 are arranged at intervals. The cold storage chambers 101, energy-consuming chambers 301, and energy storage stations 200 correspond one-to-one, allowing the energy storage station 200 to switch between different chambers. This configuration not only improves the system's flexibility but also allows for adjustments based on actual needs, ensuring efficient energy storage and release processes. For example, when the energy storage and release system is in energy storage mode, the energy storage station 200 is installed in the cold storage chamber 101, and the energy storage mechanism cools the energy storage liquid; when the energy storage and release system is in energy release mode, the energy storage station 200 is installed in the energy-consuming chamber 301, and the energy-consuming station 300 draws on the cold energy from the energy storage station 200.

[0055] In some embodiments of this utility model, the energy storage station 100 and the energy consumption station 300 are separate structures, which makes it easier for users to carry and use the energy storage and dissipation system in different scenarios.

[0056] For example, the energy storage station 100 can be designed as a separate module, containing components such as a compressor 120, a condenser 130, and an evaporator 140, for storing cold energy during periods of low electricity costs. The energy consumption station 300 can be designed as another separate module, containing components such as a radiator 320 and a blower 330, for releasing energy during periods of high electricity costs. The energy storage station 100 and the energy consumption station 300 can be connected and disconnected via a detachable connection device, allowing users to choose whether to connect or disconnect as needed, thus achieving portability and flexibility.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
