Description

Technical Field

[0001] This application belongs to the technical field of energy storage devices, and more specifically, relates to a container housing and an energy storage container. Background Art

[0002] Energy storage containers are generally used to store chemical batteries. Chemical batteries are relatively sensitive to temperature changes. Excessive low temperature will damage the batteries, and excessive high temperature or large temperature rise within a short period of time will cause risks such as battery thermal runaway. The temperature consistency of chemical batteries affects the performance and service life of the entire energy storage system. In related technologies, ventilation is usually used for heat dissipation when the temperature of chemical batteries is too high, and heat insulation is usually used for heat preservation when the temperature of chemical batteries is too low. The heat insulation method usually involves evacuating the interlayer inside the housing of the energy storage container to reduce the air concentration, thereby reducing heat exchange. However, due to the large temperature difference between day and night in high-altitude areas, ventilation is required when the external space temperature is too high during the day; heat insulation is required when the external space temperature is too low at night, resulting in frequent evacuation of the housing of the energy storage container, which in turn causes the housing of the energy storage container to sink inward, and then causes the inner and outer interlayers of the housing of the energy storage container to fit together to form a cold bridge, resulting in a significant reduction in the heat insulation effect. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a container housing and an energy storage container to solve the technical problem in the prior art that the housing of the energy storage container is prone to sink inward due to frequent evacuation.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] Provide a container housing, including: an outer wall, having an arc-shaped structure; an inner wall, having an arc-shaped structure; the arc-shaped structure of the inner wall has an opening facing the outer wall, and the arc-shaped structure of the outer wall has an opening facing the inner wall; a first connecting member, one end fixedly connected to one end of the outer wall facing the inner wall, and the other end fixedly connected to one end of the inner wall facing the outer wall; the first connecting member is a heat insulation structure; a second connecting member, one end fixedly connected to the other end of the outer wall facing the inner wall, and the other end fixedly connected to the other end of the inner wall facing the outer wall; the second connecting member is a heat insulation structure; the outer wall, the inner wall, the first connecting member, and the second connecting member jointly enclose a ring structure.

[0006] In one embodiment, it further includes: a support structure, connected to the ring structure for restricting the ring structure from sinking inward; the support structure is a heat insulation structure.

[0007] In one embodiment, the support structure includes: a central member disposed in the middle of the annular structure, the central member being a heat insulation structure; a support member having one end connected to the annular structure and the other end connected to the central member, configured to limit the annular structure from denting towards the central member; the support member being a heat conduction structure.

[0008] In one embodiment, the support member includes: a first support member having one end connected to the outer wall and the other end connected to the central member, configured to limit the outer wall from approaching the central member; the first support member being a heat conduction structure.

[0009] In one embodiment, the support member includes: a second support member having one end connected to the inner wall and the other end connected to the central member, configured to limit the inner wall from approaching the central member; the second support member being a heat conduction structure.

[0010] In one embodiment, the support member further includes: a third support member having one end connected to the first connecting member and the other end connected to the central member, configured to limit the first connecting member from approaching the central member.

[0011] In one embodiment, the support member further includes: a fourth support member having one end connected to the second connecting member and the other end connected to the central member, configured to limit the second connecting member from approaching the central member.

[0012] In one embodiment, a plurality of the annular structures are provided and are connected in sequence; the first connecting member and the adjacent second connecting member are fixedly connected, and the second connecting member and the adjacent first connecting member are fixedly connected.

[0013] In one embodiment, the first connecting member and the adjacent second connecting member are an integrally formed structure.

[0014] There is also provided an energy storage container, including: an energy storage assembly; the above-mentioned container housing, and the energy storage assembly is installed inside the container housing.

[0015] The beneficial effects of the container housing and the energy storage container provided in this application are as follows:

[0016] The container housing provided by this application includes: an outer wall, an inner wall, a first connecting member, and a second connecting member. The outer wall has an arc-shaped structure, and the inner wall also has an arc-shaped structure. The opening of the arc-shaped structure of the inner wall faces the outer wall, and the opening of the arc-shaped structure of the outer wall faces the inner wall, that is, the inner wall and the outer wall are arranged opposite to each other; one end of the first connecting member is fixedly connected to one end of the outer wall facing the inner wall, and the other end of the first connecting member is connected to one end of the inner wall facing the outer wall; one end of the second connecting member is fixedly connected to the other end of the outer wall facing the inner wall, and the other end of the second connecting member is connected to the other end of the inner wall facing the outer wall; the outer wall, the inner wall, the first connecting member, and the second connecting member jointly enclose a ring structure, and both the first connecting member and the second connecting member are heat-insulating structures.

[0017] In this application, the outer wall, the inner wall, the first connecting member, and the second connecting member jointly enclose a ring structure, and both the outer wall and the inner wall are arc-shaped structures. When a vacuum state exists between the outer wall and the inner wall, the outer wall and the inner wall will be subjected to the acting force of atmospheric pressure. When this acting force acts on the outer surfaces of the arc-shaped outer wall and inner wall, this acting force will be decomposed into a shear force along the radial direction and a pressure perpendicular to the radial direction. Since the outer wall, the inner wall, the first connecting member, and the second connecting member jointly form a ring structure, the pressure perpendicular to the radial direction will cause the above four to squeeze each other. For materials such as metal and concrete that can be used to make the outer wall and the inner wall, their ability to withstand pressure is much greater than their ability to withstand shear force. Therefore, the container housing provided by this application can maintain a stable shape in a vacuum state, and thus the outer wall and the inner wall cannot be directly connected to form a cold bridge; and both the first connecting member and the second connecting member are heat-insulating structures, and the outer wall and the inner wall cannot form a cold bridge through the first connecting member and the second connecting member.

[0018] In summary, the container housing provided by this application can maintain the stable shapes of the outer wall and the inner wall in a vacuum state, can prevent the formation of a cold bridge between the outer wall and the inner wall, and thus can effectively guarantee the heat-insulating effect of the overall structure.

[0029] Now, the container housing and the energy storage container provided by the embodiments of the present application will be described.

[0030] As Figure 1 、 Figure 2 and Figure 3 shown, the container housing 100 provided by the present application includes: an outer wall 110, an inner wall 120, a first connecting member 131, and a second connecting member 132.

[0031] The outer wall 110 has an arc-shaped structure. Specifically, the outer wall 110 can be a part of a spherical structure or a part of the side wall of a cylindrical structure; for the convenience of production and manufacturing, in this application, the case where the outer wall 110 is a part of the side wall of a cylindrical structure is taken as an example for illustration. Specifically, the outer wall 110 can be formed by a small part cut from the surface of a cylinder in a direction parallel to the axis, that is, the cross-sections of the outer surface and the inner surface of the outer wall 110 are both minor arcs.

[0032] The inner wall 120 has an arc-shaped structure. Specifically, the inner wall 120 can be a part of a spherical structure or a part of the side wall of a cylindrical structure; for the convenience of production and manufacturing, in this application, the case where the inner wall 120 is a part of the side wall of a cylindrical structure is taken as an example for illustration. Specifically, the inner wall 120 can be formed by a small part cut from the surface of a cylinder in a direction parallel to the axis, that is, the cross-sections of the outer surface and the inner surface of the inner wall 120 are both minor arcs.

[0033] The arc-shaped structure of the inner wall 120 opens towards the outer wall 110, and the arc-shaped structure of the outer wall 110 opens towards the inner wall 120. Specifically, the opening of the arc-shaped structure refers to the orientation of the concave side in the arc-shaped structure. That is, the inner wall 120 and the outer wall 110 are arranged oppositely.

[0034] One end of the first connecting member 131 is fixedly connected to one end of the outer wall 110 facing the inner wall 120. Specifically, the first connecting member 131 can be fixedly connected to the outer wall 110 by means such as welding and bonding, or can be fixedly connected to the outer wall 110 by structures such as snaps and screws. In a specific embodiment of this application, the first connecting member 131 is fixedly connected to the outer wall 110 by means of bonding to simplify the structure. The other end of the first connecting member 131 is fixedly connected to one end of the inner wall 120 facing the outer wall 110. Specifically, the first connecting member 131 can be fixedly connected to the inner wall 120 by means such as welding and bonding, or can be fixedly connected to the inner wall 120 by structures such as snaps and screws. In a specific embodiment of this application, the first connecting member 131 is fixedly connected to the inner wall 120 by means of bonding to simplify the structure.

[0035] The first connecting member 131 is a heat-insulating structure. By using the first connecting member 131, it is possible to prevent one end of the inner wall 120 and one end of the outer wall 110 from coming into direct contact, and prevent the formation of a cold bridge after their contact, thereby ensuring the heat preservation effect of the overall structure.

[0036] One end of the second connecting member 132 is fixedly connected to the other end of the outer wall 110 facing the inner wall 120. Specifically, the second connecting member 132 can be fixedly connected to the outer wall 110 by means such as welding and bonding, or can be fixedly connected to the outer wall 110 through structures such as snap fasteners and screws. In a specific embodiment of the present application, the second connecting member 132 is fixedly connected to the outer wall 110 by means of bonding to simplify the structure. The other end of the second connecting member 132 is fixedly connected to the other end of the inner wall 120 facing the outer wall 110. Specifically, the second connecting member 132 can be fixedly connected to the inner wall 120 by means such as welding and bonding, or can be fixedly connected to the inner wall 120 through structures such as snap fasteners and screws. In a specific embodiment of the present application, the second connecting member 132 is fixedly connected to the inner wall 120 by means of bonding to simplify the structure.

[0037] The second connecting member 132 is a heat-insulating structure. By using the second connecting member 132, it is possible to prevent the other ends of the inner wall 120 and the outer wall 110 from directly contacting each other, and prevent a cold bridge from being formed after their contact, thereby ensuring the heat preservation effect of the overall structure.

[0038] The outer wall 110, the inner wall 120, the first connecting member 131, and the second connecting member 132 jointly enclose a ring structure. A cavity is formed inside the ring structure. When the cavity is in a negative pressure state, the atmospheric pressure acts on the inner wall 120 and the outer wall 110. Since both the inner wall 120 and the outer wall 110 bulge outwards, the forces exerted by the atmospheric pressure on the inner wall 120 and the outer wall 110 will be decomposed into shear forces parallel to the radial direction and pressure forces perpendicular to the radial direction. The inner wall 120 and the outer wall 110 respectively bear the shear forces, while the pressure forces are borne by the first connecting member 131 and the second connecting member 132. Since part of the force is decomposed into pressure forces, the overall structure can withstand greater forces.

[0039] In this application, the outer wall 110, the inner wall 120, the first connecting member 131, and the second connecting member 132 jointly enclose a ring structure, and both the outer wall 110 and the inner wall 120 are arc-shaped structures. When a vacuum state exists between the outer wall 110 and the inner wall 120, the outer wall 110 and the inner wall 120 will be subjected to the acting force of atmospheric pressure. When this acting force acts on the outer surfaces of the arc-shaped outer wall 110 and inner wall 120, this acting force will be decomposed into a shear force along the radial direction and a pressure perpendicular to the radial direction. Since the outer wall 110, the inner wall 120, the first connecting member 131, and the second connecting member 132 jointly form a ring structure, the pressure perpendicular to the radial direction will cause the above four to squeeze each other. For materials such as metal and concrete that can be used to make the outer wall 110 and the inner wall 120, their ability to withstand pressure is much greater than their ability to withstand shear force. Therefore, the container housing 100 provided in this application can maintain a stable shape in a vacuum state, and further, the outer wall 110 and the inner wall 120 cannot be directly connected to form a cold bridge; and both the first connecting member 131 and the second connecting member 132 are heat-insulating structures, and the outer wall 110 and the inner wall 120 cannot form a cold bridge through the first connecting member 131 and the second connecting member 132.

[0040] In summary, the container housing 100 provided in this application can maintain the stable shapes of the outer wall 110 and the inner wall 120 in a vacuum state, can prevent a cold bridge from being formed between the outer wall 110 and the inner wall 120, and further can effectively guarantee the heat-insulating effect of the overall structure.

[0042] The support structure 140 is connected to the ring structure, and the support structure 140 is used to limit the inward depression of the ring structure. Specifically, one end of the support structure 140 abuts against one side of the ring structure, and the other end of the support structure 140 abuts against the other side of the ring structure to limit the inward depression of the ring structure. Specifically, the support structure 140 can be fixedly connected to the ring structure or can be axially slidably connected to the ring structure relative to the ring structure, as long as the support structure 140 can provide support for the ring structure to limit the inward depression of the ring structure.

[0043] In some embodiments of this application, the support structure 140 includes: a central member 141 and a support member 142.

[0044] The central member 141 is disposed in the middle of the ring structure. Specifically, the middle of the ring structure refers to the cavity formed between the ring structures, and the central member 141 does not abut against the side wall of the ring structure.

[0045] One end of the support member 142 is connected to the annular structure. Specifically, one end of the support member 142 can be fixedly connected to the annular structure, or can be rotatably connected or slidably connected, as long as the support member 142 can apply a radially outward support force to the annular structure. In a specific embodiment of the present application, one end of the support member 142 is fixedly connected to the annular structure to ensure that the support member 142 can work stably. The other end of the support member 142 is connected to the central member 141. Specifically, the other end of the support member 142 can be fixedly connected to the central member 141, or can be rotatably connected or slidably connected, as long as the support member 142 can transfer the force acting radially inward on the annular structure to the central member 141. In a specific embodiment of the present application, one end of the support member 142 is fixedly connected to the central member 141 to ensure that the support member 142 can work stably.

By using the central member 141, heat exchange between different support members 142 can be prevented, thereby preventing heat exchange between the inner wall 120 and the outer wall 110.

For example, the first support member 143 can be made of at least one of metals such as copper, iron, and aluminum. By using the first support member 143, heat exchange can be carried out with the outer wall 110, so as to accelerate the heat exchange efficiency when the container housing 100 needs to use air flow for heat exchange.
