[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] An energy-saving energy storage device (hereinafter referred to as the energy storage device) is mainly composed of a shell component 100, a heat collection component, and a heat exchange component. The shell component 100 defines a closed heat exchange interval 101. The energy storage device 403 is installed in the heat exchange interval 101, and the heat exchange interval 101 constitutes the installation interval for some components of the heat exchange component and the heat collection component. The shell component 100 is made of thermal insulation material (such as polyurethane) to reduce heat dissipation in the heat exchange interval 101 and improve the overall thermal insulation effect of the energy storage device.

[0035] In some embodiments, refer to Figure 1 The aforementioned heat collection assembly includes at least one container component 203 and a heat collection component 200. The container component 203 is assembled within the heat exchange interval 101 and contains a heat exchange liquid. The outer wall of the container component 203 is covered with an insulation board to improve the overall insulation effect of the energy storage device. Correspondingly, referring to… Figure 4The heat collection component 200 is assembled outside the housing component 100, i.e., outside the heat exchange zone 101. The heat collection component 200 is made of metal and can heat up under sunlight to collect heat. Preferably, the upper surface of the heat collection component 200 is coated with a black paint to improve its heating effect. For example, the top surface of the housing component 100 is provided with a groove to accommodate the heat collection component 200. Figure 1 Continuing with the description of the heat collection assembly, the aforementioned heat collection assembly also includes a heat conduction component. This heat conduction component is configured to transfer the heat from the heat collection component 200 to the heat exchange liquid, i.e., to realize heat transfer between the heat collection component 200 and the heat exchange liquid. In some examples, the heat conduction component includes at least one connecting rod 201 and a heat exchange plate 202. The connecting rod 201 is made of a thermally conductive material (such as a metal like copper) and is used to transfer the heat from the heat collection component 200 to the heat exchange plate. Specifically, one end of the connecting rod 201 is connected to the heat collection component 200, and the other end passes through the housing component 100 sequentially. The wall of the heat collector 200 and the container component 203 extends into the container component 203 and connects to the heat exchange plate 202. When the heat collector 200 is in a solar-irradiated environment, the temperature of the heat collector 200 rises and the heat is transferred to the heat exchange plate 202 through the connecting rod 201, thereby raising the temperature of the heat exchange liquid to store the heat. During periods of low ambient temperature (such as at night), the stored heat is transferred to the energy storage device 403 (described later) through the heat exchange component, so that the energy storage device 403 is not affected by the low temperature at night, ensuring the power storage effect of the energy storage device 403, and making the energy saving effect of the energy storage device 403 more ideal.

[0036] In some embodiments, refer to Figure 1 The aforementioned heat collection component 200 is a plate-shaped component. Correspondingly, the aforementioned connecting rods 201 are provided in multiple rectangular arrays, and the connecting rods 201 in different rows and / or columns have different extension lengths within the container component 203, so that the heat exchange liquid at different positions within the container component 203 can be heated synchronously. In other examples, the connecting rods 201 in the same column have equal extension lengths within the container component 203, that is, the aforementioned energy storage device has multiple connecting rods along the lateral direction (…). Figure 3 Multiple groups of connecting rods 201, spaced at intervals in the left-right direction, together form a matrix of connecting rods 201. For ease of description, refer to... Figure 2 and 3The connecting rod group 201 located in the middle of the matrix is ​​referred to as the first rod group 201a, and the connecting rod groups 201 located on both sides of the first rod group 201a are referred to as the second rod group 201b. In this example, the first rod group 201a is fixed on the shell component 100, and the second rod group 201b and the shell component 100 are connected by a sliding connection. That is, the extension length of the connecting rod 201 of the second rod group 201b in the container component 203 is adjustable. At the same time, the first rod group 201a, the second rod group 201b and the heat collection component 200 are all connected by a rotating connection (such as a hinge). At this time, the operator can rotate the heat collection component 200 to adjust the tilt angle of the heat collection component 200 (that is, the angle between the heat collection component 200 and the horizontal plane) so that the heat collection component 200 can rotate with the movement of the sun, thereby expanding the heat receiving area of ​​the heat collection component 200 and improving the heat collection efficiency of the heat collection component 200.

[0037] Reference Figure 1 and 5 The aforementioned heat exchange assembly includes a heat exchange tube body 300 and a drive component 301. A portion of the heat exchange tube body 300 is wound around the energy storage unit 403, and the two can be connected via a structure such as a slot. Both ends of the heat exchange tube body 300 extend into the container component 203, meaning that both ends of the heat exchange tube body 300 are connected to the container component 203, allowing the heat exchange liquid within the container component 203 to flow into and out of the heat exchange tube body 300, forming a heat exchange circuit. Correspondingly, the drive component 301 (such as a pump body) is configured as follows: The power source of the heat exchange circuit, namely the heat exchange liquid, can flow in the heat exchange circuit under the action of the driving component 301. Specifically, during periods of lower temperature (such as at night), the high-temperature heat exchange liquid in the container component 203 flows into the heat exchange tube body 300 under the action of the driving component 301, and exchanges heat with the energy storage device 403 in the section of the heat exchange tube body 300 that is in contact with the energy storage device 403, so that the energy storage device 403 is heated. After the heat exchange is cooled, the heat exchange liquid flows back into the container component 203 and enters the next heat exchange cycle.

[0038] In some embodiments, the container component 203 has at least one exchange port 401 on its side wall. The exchange port 401 can serve as the inlet and / or outlet of the container component 203 to allow the injection and discharge of heat exchange liquid within the container component 203, i.e., for replenishment or replacement of the heat exchange liquid. Corresponding to the exchange port 401, the energy storage device also includes at least one sealing component 400 (such as a valve). The sealing component 400 is installed based on the shell component 100 and seals the exchange port 401 on the container component 203 during the operation of the energy storage device to maintain the sealing of the shell component 100 and improve the overall operating efficiency of the device. In some examples, the sealing component 400 and the shell component 100 are configured with a threaded connection to facilitate the disassembly and assembly of the sealing component 400, thereby enabling the replenishment and replacement of the heat exchange liquid.

[0039] In some embodiments, the energy storage device further includes at least one separating component 402, which is disposed within the heat exchange zone 101 to separate the zone where the container component 203 is located from the zone where the energy storage is located, and constitutes a support carrier for the container component 203. Figure 1 The example shows a horizontally arranged partition 402 within the heat exchange zone 101. The heat exchange zone 101 is divided into upper and lower parts by this partition 402. The upper part is compatible with the specifications of the container component 203, while the lower part serves as the installation area for the energy storage device 403 and the heat collection assembly.

[0040] In some embodiments, the energy storage device further includes a support base 404 installed in the heat exchange zone 101, the support base 404 being configured to support the energy storage device 403.

[0041] When the aforementioned energy storage device is in operation, the heat collection component 200 can receive heat from the sun during the day and transfer the heat to the heat exchange plate 202 through the connecting rod 201. This allows the heat exchange plate 202 to heat the heat exchange liquid (such as water) inside the container component 203, maintaining a high temperature for the liquid. At night, when the temperature is lower, the drive component 301 pumps the high-temperature heat exchange liquid from the container component 203 into the heat exchange tube 300. This allows the high-temperature liquid to flow over the surface of the energy storage device 403 under the action of the heat exchange tube 300, providing heat to the energy storage device 403 and reducing the impact of low nighttime temperatures on the energy storage device 403. This ensures the energy storage effect of the energy storage device and makes the energy-saving effect of the energy storage device more ideal.
