[0024] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0025] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0026] Energy storage unit embodiment 1

[0027] See also Figure 1 and Figure 2 The present embodiment provides an energy storage unit 1, comprising an energy storage body 11 and at least one support 12. The energy storage body 11 is columnar, and has an inner cavity for containing phase change material. The support 12 is fixed to the energy storage body 11, and has a bottom plate 121, and the bottom plate 121 is parallel to the central axis L of the energy storage body 11. When the energy storage unit 1 of the present embodiment is applied to the container field, generally a plurality of them are arranged in the container, and the energy storage units 1 are usually filled with foaming material 4.

[0028] When installing the energy storage unit 1 of this embodiment, it is only necessary to orient the support 12 toward the area to be installed and to fit the bottom plate 121 to the installation surface. When the bottom plate 121 is placed on the installation surface, the energy storage body 11 can maintain a stable placement in the installation area, and there is no need to use fixing tape to tie multiple energy storage units 1. Compared with the existing energy storage tube, the energy storage unit 1 of this embodiment is more convenient to install and fix, which not only saves installation and fixing materials, but also effectively improves production efficiency.

[0029] See also Figure 1 The energy storage body 11 of this embodiment includes a main body 111, a sealing part 112 and a bottle mouth 113. The sealing part 112 is fixedly connected to one end of the main body 111, and the bottle mouth 113 is fixedly connected to the other end of the main body 111.

[0030] In this embodiment, the main body 111 is cylindrical, that is, the cross section of the main body 111 is circular. In other preferred embodiments, the cross section of the main body 111 may also be square, oval, or other shapes. The main body 111 with a circular cross section has a higher strength and is easier to process and manufacture.

[0031] The bottle mouth 113 of this embodiment is formed by extending outward from the end of the main body 111, and the bottle mouth 113 has an opening, and a sealing cover 114 is provided at the opening. The energy storage phase change material can be injected into the inner cavity of the energy storage body 11 through the opening of the bottle mouth 113, and the sealing cover 114 is used to seal the entire energy storage body 11. Further, the sealing part 112 is hemispherical, and the sealing part 112 is made of PE plastic. The finished sealing part 112 is fixed to the end of the main body 111 by gluing or hot-melt connection.

[0032] like Figure 1 and Figure 2 As shown, a support 12 is provided in the energy storage unit 1 of this embodiment. In the support 12 of this embodiment, both ends of the bottom plate 121 in the width direction exceed the outside of the energy storage body 11. When multiple energy storage units 1 are arranged and installed, the opposite end surfaces of the bottom plates 121 in two adjacent energy storage units 1 are abutted against each other, so that there is a gap between the two adjacent energy storage bodies 11. The gap between the two adjacent energy storage bodies 11 can ensure the fluidity of the foaming material 4 between the energy storage units 1 and ensure uniform foaming.

[0033] Preferably, the bottom plate 121 of this embodiment is connected to the energy storage body 11 through a support plate 122 to ensure the stability of the structure of the support 12 itself and the connection strength between the bottom plate 121 and the energy storage body 11. Specifically, the support plate 122 is perpendicular to the bottom plate 121, the cross section of the support 12 is T-shaped, and one end of the support plate 122 away from the bottom plate 121 is fixedly connected to the outer surface of the energy storage unit 1.

[0034] In this embodiment, the support plate 122 is vertically arranged on the outer surface of the main body 111 of the energy storage unit 1. Preferably, the support 12 of this embodiment is integrally formed with the main body 111. This arrangement simplifies the manufacturing process of the energy storage unit 1 while ensuring the stability of the connection between the support 12 and the energy storage body 11.

[0035] Furthermore, in this embodiment, the bottom plate 121 and the support plate 122 both extend along the length direction of the energy storage body 11, that is, both ends of the bottom plate 121 and the support plate 122 in the length direction are close to both ends of the main body 111. This arrangement can ensure that when the energy storage unit 1 is placed, it has a large contact area with the external environment (such as: the side plate, end plate, bottom frame, etc. of the container), and effectively ensures the stability of the energy storage unit 1 during installation.

[0036] It should be noted that in some other preferred embodiments, the support 12 may be provided in plurality, wherein the length of the support 12 is less than the length of the energy storage body 11, and the plurality of supports 12 are arranged at intervals along the length direction of the energy storage body 11, which can also ensure that the energy storage unit 1 is stably placed.

[0037] When the energy storage unit 1 of this embodiment is used in the container field, the energy storage unit 1 can be set in the wall 2 of the container, or arranged between the bottom frame and the floor 3 of the container. The wall 2 can be the side wall of the container or the end wall of the container; the floor 3 can be a T-floor or other types of floors.

[0038] When the energy storage unit 1 of this embodiment is applied to the container wall 2, refer to Figure 3 The wall 2 of the container includes an inner wall 21 and an outer wall 22, and the energy storage unit 1 is arranged between the inner wall 21 and the outer wall 22. The energy storage unit 1 is provided in plurality, and the plurality of energy storage units 1 are continuously arranged in the wall 2 along the length / width direction of the wall 2. When the plurality of energy storage units 1 are arranged along the length direction of the wall 2, the central axis L of the energy storage body 11 is parallel to the width direction of the wall 2; when the plurality of energy storage units 1 are arranged along the width direction of the wall 2, the central axis L of the energy storage body 11 is parallel to the length direction of the wall 2.

[0039] Furthermore, when the energy storage unit 1 is arranged in the wall 2, the bottom surface of the bottom plate 121 abuts against the inner wall of the inner wall 21 or the outer wall 22, and the top of the energy storage body 11 is tangent to the inner wall of the outer wall 22 or the inner wall 21. For two adjacent energy storage units 1, the opposite end surfaces of the bottom plates 121 of the two abut against each other, so that there is a gap between the two adjacent energy storage bodies 11 to facilitate the flow of the foaming material 4.

[0040] When the energy storage unit 1 of this embodiment is applied between the bottom frame and the floor 3 of the container, Figure 4 The energy storage unit 1 is provided in a plurality, and the plurality of energy storage units 1 are continuously arranged along the length direction of the floor 3, wherein the central axis of the energy storage body 11 is parallel to the width direction of the floor 3. Further, when the energy storage unit 1 is arranged between the base frame and the floor 3, the bottom surface of the bottom plate 121 abuts against the upper surface of the base frame, and the opposite end surfaces of the bottom plates 121 of two adjacent energy storage units 1 abut against each other.

[0041] Energy storage unit embodiment 2

[0042] The energy storage unit 1 of this embodiment is substantially the same as that of the embodiment 1, and the main difference is that: Figure 5 There are multiple supports 12 in the energy storage unit 1. In this embodiment, the energy storage unit 1 includes three supports 12, and the three supports 12 are arranged at intervals along the circumference of the energy storage body 11.

[0043] The structures of the energy storage body 11 and the support 12 in this embodiment are the same as those of the energy storage unit 1 in Embodiment 1, and will not be described in detail here. In this embodiment, the three supports 12 are respectively a support support 12a and two stop supports 12b. Among them, the two stop supports 12b are symmetrically arranged on both sides of the support support 12a, and the two stop supports 12b are respectively arranged at the two ends of the radial direction of the energy storage body 11.

[0044] When the energy storage unit 1 of this embodiment is used in the container field, the energy storage unit 1 can be arranged in the wall 2 of the container, or can be arranged between the bottom frame and the floor 3 of the container.

[0045] When the energy storage unit 1 of this embodiment is applied to the wall 2 of the container, refer to Figure 6 , multiple energy storage units 1 are continuously arranged along the length / width direction of the wall 2 between the outer wall 22 and the inner wall 21. When multiple energy storage units 1 are arranged along the length direction of the wall 2, the central axis L of the energy storage body 11 is parallel to the width direction of the wall 2; when multiple energy storage units 1 are arranged along the width direction of the wall 2, the central axis L of the energy storage body 11 is parallel to the length direction of the wall 2.

[0046] Furthermore, when the energy storage unit 1 of this embodiment is arranged in the wall 2, the bottom surface of the support bracket 12a abuts against the inner wall of the inner wall 21 or the outer wall 22, and the top of the energy storage body 11 is tangent to the inner wall of the outer wall 22 or the inner wall 21. For two adjacent energy storage units 1, the bottom plates 121 of the opposing stop brackets 12b of the two abut against each other, so that there is a gap between the two adjacent energy storage bodies 11 to facilitate the flow of the foaming material 4.

[0047] When the energy storage unit 1 of this embodiment is applied between the bottom frame and the bottom plate 121 of the container, a plurality of energy storage units 1 are provided, and the plurality of energy storage units 1 are arranged continuously along the length direction of the floor 3. The central axis of the energy storage body 11 is parallel to the width direction of the floor 3, the bottom surface of the support bracket 12a is in contact with the upper surface of the bottom frame, and the bottom plates 121 of the opposite stop brackets 12b of two adjacent energy storage units 1 are in contact with each other.

[0048] The present application also provides a thermal insulation / refrigerated container, which includes a wall 2, and the wall 2 includes an inner wall 21 and an outer wall 22. Among them, a plurality of the above-mentioned energy storage units 1 are arranged between the outer wall 22 and the inner wall 21. The plurality of energy storage units 1 are continuously arranged along the length / width direction of the wall 2, and the specific arrangement is described in detail in the energy storage unit embodiment 1 and the energy storage unit embodiment 2, which will not be repeated here.

[0049] In addition, the present application also provides a thermal insulation / refrigerated container, which includes a base frame and a floor 3 arranged above the base frame. Among them, a plurality of the above-mentioned energy storage units 1 are arranged between the base frame and the floor 3, and the plurality of energy storage units 1 are continuously arranged along the length direction of the floor 3. The specific arrangement is described in detail in the energy storage unit embodiment 1 and the energy storage unit embodiment 2, and will not be repeated here.

[0050] In summary, when installing the energy storage unit of the present application, it is only necessary to point the support toward the area to be installed so that the bottom plate fits the installation surface, and there is no need to use fixing tape for bundling. Compared with the existing energy storage tube, the energy storage unit is more convenient to install and fix. When the energy storage unit is used in an insulated / refrigerated container, it can not only save the cost of fixing tape, but also simplify the installation steps and improve the production efficiency of the insulated / refrigerated container. In addition, when multiple energy storage units are arranged in a container, the support can also ensure that there is a gap between two adjacent energy storage bodies for the flow of foaming materials, and there is no need to reserve a gap between the energy storage units during installation.
