Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a coolant connection device and energy storage system. Background Technology
[0002] Currently, all containerized batteries require a coolant connection to cool them and prevent thermal runaway. However, in marine applications, the batteries are prone to movement, making it difficult to align the coolant interface between the battery and the container during docking.

[0013] In conjunction with the first aspect, in one possible implementation, the coolant connection device further includes a cooling base, the cooling base being provided with a refrigerant output interface and a refrigerant recovery interface, the refrigerant output interface being connected to the first pipe, the refrigerant output interface being connected to the second pipe, and the refrigerant output interface and the refrigerant recovery interface being spaced apart.
[0014] In conjunction with the first aspect, in one possible implementation, the coolant connection device further includes a cooling tank, which is independently disposed and fixedly connected to the cooling base; or, the cooling tank and the cooling base are connected to form an integral structure.
[0015] Secondly, this utility model provides an energy storage system, including a device to be cooled and a coolant connection device as described above, wherein the coolant connection device is used to dissipate heat from the device to be cooled.
[0016] In conjunction with the second aspect, in one possible implementation, the device to be cooled is configured as a container battery, which contains a battery cluster and cooling pipes. The cooling pipes are connected between the refrigerant inlet connector and the refrigerant outlet connector and are thermally connected to the battery cluster.
[0017] The coolant connection device and energy storage system provided by this utility model are based on a first diameter difference between the inner diameter of the first pipe connecting to the refrigerant inlet connector and the outer diameter of the refrigerant inlet connector. The first diameter difference is greater than the amount of swaying of the device to be cooled relative to the cooling contact device. A second diameter difference is configured between the inner diameter of the first pipe connecting to the refrigerant outlet connector and the outer diameter of the refrigerant outlet connector. The second diameter difference is greater than the amount of swaying of the device to be cooled relative to the cooling contact device. Thus, the first pipe and the second pipe can allow for swaying displacement deviation, thereby improving the success rate and assembly efficiency of the connection between the device to be cooled and the coolant connection device under swaying conditions. The coolant connection device has a simple structure, reducing production and maintenance costs. Attached Figure Description

[0023] The following description of various embodiments of the present invention is based on the accompanying drawings.
[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" means that the components are connected to each other and their relative positional relationship remains unchanged after connection.

The term "integral molding" means that during the formation of one of a plurality of components, that component is connected to the other components without requiring further processing (such as bonding, welding, snap-fit connection, screw connection) to connect the two components together. The directional terms mentioned in the embodiments of this utility model, such as "top," "bottom," "inner," "outer," and "side," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.
[0025] Please see Figure 1 , Figure 1 This is a first exploded view of the energy storage system 1000 provided in the first embodiment of this utility model. The energy storage system 1000 includes a device to be cooled 100 and a coolant connection device 200. The coolant connection device 200 is used to dissipate heat from the device to be cooled 100, so that the cooling device can dissipate the heat of the device to be cooled 100 in a timely manner, thereby improving the service life of the device to be cooled 100.
[0026] For example, in this embodiment, the device to be cooled 100 is configured as a container battery. The container battery contains battery clusters 110 and cooling pipes 120. The cooling pipes 120 connect the refrigerant inlet connector 102 and the refrigerant outlet connector 103, and are thermally connected to the battery clusters 110. The cooling pipes 120 can quickly dissipate the heat generated by the battery clusters 110 to the outside through the flowing refrigerant, thereby improving the service life of the battery clusters 110. Of course, in some embodiments, the device to be cooled 100 can also be a cabinet battery, a box battery, or other energy storage devices with larger volume, higher energy density, and multiple battery packs. The refrigerant may include, but is not limited to, fluid substances such as water and oil.
[0027] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement of the cooling device 100 and the coolant connection device 200, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1This illustration only shows the structure of the energy storage system 1000 in an embodiment of the present invention and does not constitute a specific limitation on the energy storage system 1000. In other embodiments of the present invention, the energy storage system 1000 may include more than Figure 1 The energy storage system 1000 may include more or fewer components, or combinations of certain components, or different components, and may also include, but is not limited to, a refrigerant supply device, a temperature detector, etc.
[0028] A coolant connection device 200 is used to connect to the device 100 to be cooled. The outer wall 101 of the device 100 to be cooled is provided with a refrigerant inlet connector 102 and a refrigerant outlet connector 103 communicating with the refrigerant inlet connector 102. The coolant connection device 200 includes a first pipe 20 and a second pipe 40. The first pipe 20 is used for pluggable connection to the refrigerant inlet connector 102. The second pipe 40 is arranged side-by-side with the first pipe 20 and is used for pluggable connection to the refrigerant outlet connector 103. Specifically, the inner diameter of the first pipe 20 at the end connecting to the refrigerant inlet connector 102 is configured with a first diameter difference from the outer diameter of the refrigerant inlet connector 102, which is greater than the amount of sway of the device 100 to be cooled relative to the cooling contact device. The inner diameter of the first pipe 20 at the end connecting to the refrigerant outlet connector 103 is configured with a second diameter difference from the outer diameter of the refrigerant outlet connector 103, which is also greater than the amount of sway of the device 100 to be cooled relative to the cooling contact device.
[0029] The coolant connection device 200 provided by this utility model is based on a first diameter difference between the inner diameter of one end of the first pipe 20 connected to the refrigerant inflow connector 102 and the outer diameter of the refrigerant inflow connector 102. The first diameter difference is greater than the amount of sway of the device to be cooled 100 relative to the cooling contact device. A second diameter difference is also configured between the inner diameter of one end of the refrigerant outflow connector 103 and the outer diameter of the refrigerant outflow connector 103. The second diameter difference is greater than the amount of sway of the device to be cooled 100 relative to the cooling contact device. Thus, the first pipe 20 and the second pipe 40 can allow for swaying displacement deviation, thereby improving the success rate and assembly efficiency of the connection between the device to be cooled 100 and the coolant connection device 200 under swaying conditions. The coolant connection device 200 has a simple structure, reducing production and maintenance costs.
[0030] At least a portion of the first conduit 20 and at least a portion of the second conduit 40 are both configured as telescopic conduits. The coolant connection device 200 also includes an elastic element 50. The elastic element 50 is fitted onto at least one of the first conduit 20 and the second conduit 40. When the first conduit 20 and the second conduit 40 are in sealing contact with the mounting outer wall 101, the elastic element 50 is in a compressed state and provides an elastic force to the first conduit 20 and the second conduit 40 in the direction from the coolant connection device 200 to the device to be cooled 100. Therefore, on the one hand, the elastic force of the elastic element 50 can tightly abut the first pipe 20 and the second pipe 40 against the side wall of the device to be cooled 100, thereby achieving a sealed connection between the device to be cooled 100 and the sealing element 60. This prevents the coolant from easily leaking at the connection between the device to be cooled 100 and the coolant connector 200, thus improving the safety of the device to be cooled 100. On the other hand, the telescopic pipe improves the flexibility of the first pipe 20 and the second pipe 40 to be connected to the refrigerant inlet connector 102 and the refrigerant outlet connector 103 respectively. The elastic element 50 provides a sealing clamping force for the sealing element 60. The coolant connector 200 has a simple structure, reducing production and maintenance costs.
[0031] In the first embodiment, both portions of the first pipe 20 and the second pipe 40 are configured as non-expandable pipes. It should be noted that a non-expandable pipe refers to a structure in which the extension length of the pipe does not change in the extension direction. For example, the extension length of the first pipe 20 does not change in the extension direction, and neither does the extension length of the second pipe 40. An expandable pipe refers to a structure in which the extension length of the pipe changes in the extension direction.
[0032] The first pipe 20 and the second pipe 40 are both flared in shape. Specifically, the radial cross-sectional areas of both the first pipe 20 and the second pipe 40 gradually increase along the direction from the coolant connector 200 to the device to be cooled 100. This allows the first pipe 20 and the second pipe 40 to tolerate swaying displacement deviations, thereby improving the success rate and assembly efficiency of the connection between the device to be cooled 100 and the coolant connector 200 under swaying conditions. The coolant connector 200 has a simple structure, reducing production and maintenance costs.
[0033] Please refer to the following: Figure 1 and Figure 2 , Figure 2This is a first exploded view of the energy storage system 1000 provided in the second embodiment of this utility model. The structure of the energy storage system 1000 in the second embodiment is similar to that of the energy storage system 1000 in the first embodiment. The difference is that, in the second embodiment, both the first pipe 20 and the second pipe 40 are configured as telescopic pipes. Specifically, the first pipe 20 includes a first pipe section 21 and a second pipe section 22 connected to the end of the first pipe section 21 facing away from the cooling device 100. The second pipe 40 includes a third pipe section 41 and a fourth pipe section 42 connected to the end of the third pipe section 41 facing away from the cooling device 100. The first pipe section 21 and the third pipe section 41 are configured as telescopic pipes, while the second pipe section 22 and the fourth pipe section 42 are configured as rigid pipes, thereby facilitating the insertion and connection of the ends of the first pipe 20 and the second pipe 40 facing away from the cooling device 100 with the cold source equipment, improving the assembly efficiency and assembly yield of the first pipe 20 and the second pipe 40 with the cold source equipment. The telescopic pipe is a corrugated pipe. Of course, in some embodiments, the telescopic pipe can also be a stacked pipe. The elastic element 50 is configured as a spring. Of course, in some embodiments, the elastic element 50 may also be configured as a sheet.
[0034] The first pipe section 21 and the second pipe section 22 are configured with a non-equal diameter structure. The radial cross-sectional area of both the first pipe section 21 and the second pipe section 22 gradually increases along the direction from the coolant connector 200 to the device to be cooled 100. This allows the first pipe 20 and the second pipe 40 to tolerate swaying displacement deviations, thereby improving the success rate and assembly efficiency of the connection between the device to be cooled 100 and the coolant connector 200 under swaying conditions. The coolant connector 200 has a simple structure, reducing production and maintenance costs. The second pipe section 22 and the fourth pipe section 42 are configured with an equal diameter structure, improving the reliability and sealing of the connection between the coolant connector 200 and the device to be cooled 100.
[0035] Of course, in some embodiments, both the first pipe 20 and the second pipe 40 are configured as telescopic pipes. The structural configuration of the first pipe 20 and the second pipe 40 can be set according to actual conditions, and this embodiment of the utility model does not impose specific limitations.
[0036] Please refer to it again. Figure 1 and Figure 2The coolant connection device 200 also includes a sealing element 60, which is fixedly connected to one end of the first pipe 20 near the device to be cooled 100 and / or one end of the second pipe 40 near the device to be cooled 100. The sealing element 60 extends along the radial direction of the first pipe 20 and / or the second pipe 40 and abuts against the elastic element 50. Therefore, by extending the sealing element 60 along the radial direction of the first pipe 20 and abutting against the elastic element 50, the contact area between the sealing element 60 and the mounting sidewall is increased, improving the sealing capability between the sealing element 60 and the mounting sidewall. Exemplarily, in this embodiment, the sealing element 60 is fixedly connected to one end of the first pipe 20 near the device to be cooled 100 and one end of the second pipe 40 near the device to be cooled 100, thereby establishing a continuous, stable, and sealed channel between the two independent first pipes 20 and second pipes 40 to achieve safe, efficient, and leak-free refrigerant transmission. Of course, in some embodiments, the sealing element 60 may also be fixedly connected to either the first pipe 20 or the second pipe 40.
[0037] In this embodiment, for example, the seal 60 includes a sealing surface 601 for sealingly abutting against the mounting outer wall 101. The sealing surface 601 protrudes from the end face of the first pipe 20 facing the device 100 to be cooled and the end face of the second pipe 40 facing the device 100 to be cooled. The seal 60 is provided with a first through hole 602 and a second through hole 603. A refrigerant inlet connector 102 is sequentially and detachably inserted into the first through hole 602 and the first pipe 20. A refrigerant outlet connector 103 is sequentially and detachably inserted into the second through hole 603 and the second pipe 40. Thus, by protruding the seal 60 from the ends of the first pipe 20 and the second pipe 40, the structural strength of the seal 60 is improved, stress concentration is reduced, the flatness of the sealing surface 601 is enhanced, and the reliability of the sealing connection between the sealing surface 601 and the mounting outer wall 101 is improved.
[0038] Of course, in some embodiments, the sealing surface 601 is abutted and flush with the end face of the first pipe 20 facing the device 100 to be cooled and the end face of the second pipe 40 facing the device 100 to be cooled. The refrigerant inlet connector 102 is pluggably inserted into the first pipe 20. The refrigerant outlet connector 103 is pluggably inserted into the second pipe 40. This reduces the material used for the seal 60, saving costs and space.
[0039] For example, in this embodiment, the number of elastic elements 50 is set to one. The elastic element 50 is sleeved on the outside of the first pipe 20 and the second pipe 40. Thus, by providing an elastic element 50 on the outside of the first pipe 20 and the second pipe 40, on the one hand, the number of parts is reduced, the cost is lowered, and the structure is simplified; on the other hand, the elastic element 50 can form an integral part with the first pipe 20 and the second pipe 40, improving the bending resistance and pull-out resistance of the first pipe 20 and the second pipe 40.
[0040] Of course, in some embodiments, the number of elastic elements 50 is set to two, with one of the two elastic elements 50 sleeved on the outside of the first pipe 20 and the other of the two elastic elements 50 sleeved on the outside of the second pipe 40. Thus, by setting two elastic elements 50 respectively sleeved on the outside of the first pipe 20 and the second pipe 40, on the one hand, the manufacturing tolerances and thermal expansion and contraction of the first pipe 20 and the second pipe 40 can be independently compensated and absorbed, resulting in less interference between the first pipe 20 and the second pipe 40; on the other hand, the first pipe 20 and the second pipe 40 can be installed separately, improving the convenience and flexibility of installation and maintenance operations.
[0041] For example, in this embodiment, the seal 60 is configured as an integral structure with the first pipe 20 and the second pipe 40, thereby improving the stability and reliability of the connection between the seal 60 and the first pipe 20 and the second pipe 40, as well as improving assembly efficiency. At least one of the first pipe 20 and the second pipe 40 is configured as a heat-insulating structure; and / or, the seal 60 is configured as a heat-insulating structure to prevent heat exchange between the refrigerant flowing out of the first pipe 20 and the refrigerant flowing out of the second pipe 40, which would affect the heat dissipation effect of the device 100 to be cooled.
[0042] Of course, in some embodiments, the seal 60 is configured as a separate structure from the first pipe 20 and the second pipe 40 and is fixedly connected, thereby reducing the processing and manufacturing difficulty of the seal 60 and the first pipe 20 and the second pipe 40, and improving the convenience and flexibility of cleaning, replacement and maintenance operations.
[0043] For example, in this embodiment, the first pipe 20 and the second pipe 40 are arranged independently and fixedly connected by a sealing member 60. Therefore, by setting the first pipe 20 and the second pipe 40 to be arranged independently, the risk of heat interference from the first pipe 20 and the second pipe 40 is reduced, thereby improving the heat dissipation effect of the cooling device 100.
[0044] Of course, in some embodiments, the first pipe 20 and the second pipe 40 are configured as an integral structure, thereby reducing assembly steps, improving assembly efficiency, and improving the overall compactness of the coolant connection device 200.
[0045] Please refer to the following: Figure 2 and Figure 3 , Figure 3 This is an exploded view of the pure energy storage system 1000 provided in the second embodiment of this utility model. The structure of the energy storage system 1000 in the third embodiment is similar to that of the energy storage system 1000 in the first embodiment. The difference is that, in the third embodiment, the coolant connection device 200 further includes a telescopic sleeve 70. The telescopic sleeve 70 includes a first sleeve 71 and a second sleeve 72. One end of the first sleeve 71 is telescopically connected to the second sleeve 72, and the other end of the first sleeve 71 is fixedly connected to at least one of the first pipe 20 and the second pipe 40. Therefore, on the one hand, the telescopic sleeve 70 can conceal the first pipe 20, the second pipe 40 and the elastic element 50, improving the aesthetics of the coolant connection device 200, and preventing the seal 60 from shifting and leaking due to accidental contact with the first pipe 20, the second pipe 40 or the seal 60 by the operator; on the other hand, the first sleeve 71 is telescopic relative to the second sleeve 72, thereby improving the reliability and flexibility of the connection between the first pipe 20 and the second pipe 40 and the refrigerant inflow connector 102 and the refrigerant outflow connector 103, respectively.
[0046] The telescopic sleeve 70 is fitted onto the outside of the first pipe 20 and the second pipe 40. The second sleeve 72 is fitted onto the outside of the first sleeve 71 and is provided with a first snap-fit structure 81. The first snap-fit structure 81 is used for detachable connection with the second snap-fit structure 82 provided on the cooling device 100. When the first snap-fit structure 81 and the second snap-fit structure 82 are engaged, the elastic element 50 is in a compressed state. Therefore, on the one hand, the elastic force provided by the elastic element 50 can tightly abut the first pipe 20 and the second pipe 40 against the side wall of the device to be cooled 100, thereby achieving a sealed connection between the device to be cooled 100 and the sealing element 60. This prevents the coolant from easily leaking at the connection between the device to be cooled 100 and the coolant connector 200, thus improving the safety of the device to be cooled 100. On the other hand, the mutual cooperation and fixation of the first snap-fit structure 81 and the second snap-fit structure 82 can reduce the stability and reliability of the connection between the device to be cooled 100 and the coolant connector 200 under shaking conditions. Furthermore, the telescopic sleeve 70 improves the flexibility of the first pipe 20 and the second pipe 40 to be connected to the refrigerant inlet connector 102 and the refrigerant outlet connector 103 respectively. The elastic element 50 provides a sealing clamping force for the sealing element 60. The structure of the coolant connector 200 is simple, reducing production and maintenance costs.
[0047] For example, in this embodiment, one of the first snap-fit structure 81 and the second snap-fit structure 82 is configured as a hook, and the other of the first snap-fit structure 81 and the second snap-fit structure 82 is configured as a slot that can be detachably snapped into the hook. Of course, in some embodiments, one of the first snap-fit structure 81 and the second snap-fit structure 82 is configured as a buckle, and the other of the first snap-fit structure 81 and the second snap-fit structure 82 is configured as a hole that can be detachably snapped into the buckle.
[0048] Please refer to it again. Figure 2 and Figure 3 In some embodiments, the coolant connection device 200 further includes a cooling base 91. The cooling base 91 is provided with a refrigerant output interface 92 and a refrigerant recovery interface 93. In this embodiment, the refrigerant output interface 92 and the refrigerant recovery interface 93 of the coolant connection device 200 are connected to the refrigerant supply equipment to form a closed-loop internal circulation pipeline. The closed-loop circulation pipeline then transfers the internal circulation heat to the outside through a heat exchanger, thereby preventing refrigerant evaporation, reducing energy consumption, and improving the operational stability and reliability of the coolant connection device 200.
[0049] Of course, in some embodiments, the refrigerant output port 92 and refrigerant recovery port 93 of the coolant connection device 200 are connected to the refrigerant supply equipment to form an open external circulation pipeline. The pumping device pumps refrigerant from environments such as oceans, lakes, tap water, and rivers to the device 100 to be cooled through the open external circulation pipeline. The refrigerant absorbs the heat generated by the device 100 and is then pumped to cooling towers, spray tanks, or other cooling devices or environments. The refrigerant recovered in these cooling devices or pumped into the environment exchanges heat with the atmosphere through direct contact with the air. Thus, the open external circulation pipeline directly utilizes water from the environment for cooling, eliminating the need for an intermediate heat exchanger and saving on heat dissipation costs. It should be noted that the circulation pipeline configuration of the coolant connection device 200 can be set according to actual conditions, and this embodiment of the invention does not impose specific limitations.
[0050] The refrigerant output port 92 is connected to the first pipe 20. The refrigerant output port 92 is also connected to the second pipe 40. The refrigerant output port 92 and the refrigerant recovery port 93 are spaced apart. Therefore, by placing the refrigerant output port 92 and the refrigerant recovery port 93 on the cooling base 91 and spaced them apart, heat exchange between the refrigerant flowing out of the refrigerant output port 92 and the refrigerant returning to the refrigerant recovery port 93 is avoided, thus preventing any impact on the heat dissipation effect of the device 100 to be cooled.
[0051] For example, in this embodiment, the cooling box 94 and the cooling base 91 are connected to form an integral structure, thereby improving the reliability and stability of the connection between the cooling box and the cooling base 91 and improving assembly efficiency.
[0052] Of course, in some embodiments, the coolant connection device 200 also includes a cooling tank 94. The cooling tank 94 and 91 are independently set and fixedly connected, which facilitates the replacement, maintenance and cleaning of the cooling base 91 and the cooling tank 94, and reduces the processing and manufacturing difficulty of the cooling base 91 and the cooling tank 94.
[0053] The above description is merely a specific implementation of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
