[0002] Phase change thermal energy storage refers to a technology that utilizes the absorption or release of heat by a substance during a phase change process. Its working principle is based on the solid, liquid, and gas phase changes of a substance. When the ambient temperature is higher than the phase change temperature, the material absorbs heat and changes from a solid state to a liquid or gaseous state. Conversely, it releases heat and returns to a solid or liquid state, thereby maintaining the ambient temperature at a suitable level.

[0003] According to announcement number CN222298590U, a phase change heat storage device for a heating unit is disclosed. This technology discloses "a heat exchanger and a heat storage cylinder, the top of the heat exchanger is connected to a connecting pipe, the end of the connecting pipe away from the heat exchanger is connected to the top of the heat storage cylinder, a sealing cap is threaded to the left side of the heat storage cylinder, a cleaning mechanism is provided in the inner cavity of the heat storage cylinder, a fixing mechanism is provided on the surface of the cleaning mechanism, and a conveying mechanism is provided on the right side of the heat storage cylinder. This utility model, by setting up a heat exchanger, a heat storage cylinder and a connecting pipe, can convey and store hot air.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figure 1 As shown:

[0024] A phase change heat storage device for a heating unit includes a phase change box 1.

[0025] In this implementation plan: The existing announcement number CN222298590U discloses a phase change thermal storage device for a heating unit, which adopts the same technical means as the prior art. These technical means will not be described in detail here. For details on the improvement of the prior art, please refer to the following disclosure. In order to solve the technical problems existing in the prior art, such as the "lacking a structure to stabilize the main body during use and installation of the device, the device may be displaced by external forces during long-term use, which will affect the external pipe structure and internal components, thus hindering its normal use" in combination with the use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, a left support 2 and a stabilizing rod 3 are added on the basis.

[0026] Furthermore:

[0027] like Figure 1 - Figure 5 As shown:

[0028] In conjunction with the above, it also includes a left support leg 2, a stabilizing rod 3, a lifting plate 4, a positioning plate 5, a spring 6, a right support leg 7, and a connecting hole 8, all located on one side of the phase change box 1. The left support leg 2 and the right support leg 7 are integrally formed on one side of the phase change box 1, and the surface of the right support leg 7 is provided with a connecting hole 8. The stabilizing rod 3, which is slidably connected to the lifting plate 4, is also fixedly installed on one side of the phase change box 1. The surface of the stabilizing rod 3 is also fitted with two springs 6, which are respectively fixedly connected to the surface of the phase change box 1 and the surface of the lifting plate 4. One end of the lifting plate 4 is also integrally formed with a positioning plate 5, which is slidably connected to the right support leg 7 and the connecting hole 8.

[0029] In this implementation scheme: when it is necessary to connect the various phase change boxes 1, the first phase change box 1 can be placed at the installation point first. Then, the other phase change box 1 can be lifted by lifting the lifting plate 4. At this time, the lifting plate 4 will slide with the stabilizing rod 3 and drive the positioning plate 5 to lift, and compress the spring 6 located above the lifting plate 4. At this time, the position of the phase change box 1 will be lifted. Then, the phase change box 1 in the lifted state can be placed near the first phase change box 1, and the positioning plate 5 on the surface of the lifted phase change box 1 should be aligned with the connection hole 8 opened on the side of the bottom phase change box 1. Then, the phase change box 1 can be moved horizontally. The positioning plate 5 will slide into the connection hole 8 under the action of the phase change box 1. Finally, the phase change box 1 can be lowered. At this time, the positioning plate 5 and the lifting plate 4 will slide along the connection hole 8 opened on the surface of the right support 7, and the spring 6 will also extend and reset, and assist the lifting plate 4 and the positioning plate 5 in resetting. At this time, the positioning plate 5 will fall to the bottom of the connection hole 8. At this time, the connection between the two phase change boxes 1 is completed, which can make the heating unit more stable.

[0030] Furthermore:

[0031] In an optional embodiment, a rectangular groove is formed on the surface of the left support leg 2, and the position of the groove matches the position of the two lifting plates 4.

[0032] In this embodiment, the groove on the surface of the left support leg 2 allows the lifting plate 4 to slide stably along the left support leg 2, enabling it to drive the positioning plate 5 into the interior of the connecting hole 8 and form a stable connection.

[0033] Furthermore:

[0034] In an optional embodiment, the connection between the stabilizer bar 3 and the lifting plate 4 has a through hole on the surface of the lifting plate 4 that matches the stabilizer bar 3.

[0035] In this embodiment, the through hole on the surface of the stabilizer bar 3 allows it to slide along the lifting plate 4 and compress the spring 6. Then, the spring 6 can rebound to press down and reset the lifting plate 4 and the positioning plate 5.

[0036] Furthermore:

[0037] In an optional embodiment, the lifting plate 4 and the positioning plate 5 are in the shape of a "T".

[0038] In this embodiment, the "T"-shaped lifting plate 4 and positioning plate 5 can form a stable connection with the connecting hole 8, preventing the positioning plate 5 from separating from the connecting hole 8.

[0039] Furthermore:

[0040] In an optional embodiment, the right support leg 7 and the left support leg 2 are symmetrically arranged at the bottom of the phase change box 1.

[0041] In this embodiment, the left support leg 2 and the right support leg 7 symmetrically arranged at the bottom of the phase change box 1 can provide support for the phase change box 1 while ensuring that the lifting plate 4 and the positioning plate 5 can slide along their surfaces, thereby achieving the purpose of connecting the phase change box 1 and the phase change box 1.

[0042] Furthermore:

[0043] In an optional embodiment, the connecting hole 8 is T-shaped, and the upper width of the connecting hole 8 is the same as the width of the positioning plate 5, while the lower width of the connecting hole 8 is the same as the width of the lifting plate 4.

[0044] In this embodiment, the connecting hole 8, which matches the size of the lifting plate 4 and the positioning plate 5, can form a connection between the phase change box 1 and the positioning plate 5 when the phase change box 1 is lifted, and lower it along the connecting hole 8. Thus, the connection between the lifting plate 4 and the connecting hole 8 can stabilize the phase change box 1 and the connection between the phase change boxes 1.

[0045] The working principle and usage process of this utility model are as follows: When it is necessary to connect the various phase change boxes 1, the first phase change box 1 can be placed at the installation point first. Then, the other phase change box 1 can be lifted by lifting the lifting plate 4. At this time, the lifting plate 4 will slide with the stabilizing rod 3, thereby lifting the positioning plate 5 and compressing the spring 6 located above the lifting plate 4. At this time, the position of the phase change box 1 will be lifted. Then, the phase change box 1 in the lifted state can be placed near the first phase change box 1, and the surface of the phase change box 1 in the lifted state will be set with The positioning plate 5 is aligned with the connection hole 8 on the side of the bottom phase change box 1. Then the phase change box 1 can be moved horizontally. The positioning plate 5 will slide into the connection hole 8 under the action of the phase change box 1. Finally, the phase change box 1 can be lowered. At this time, the positioning plate 5 and the lifting plate 4 will slide along the connection hole 8 on the surface of the right support leg 7. The spring 6 will also extend and reset, and assist the lifting plate 4 and the positioning plate 5 in resetting. At this time, the positioning plate 5 will fall to the bottom of the connection hole 8. At this time, the connection between the two phase change boxes 1 is completed, which can make the heating unit more stable.

[0046] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
