[0002] Battery modules used in new energy vehicles can usually be cooled by air or liquid, of which liquid cooling has a higher heat dissipation efficiency. There are many ways to cool the battery by liquid cooling, such as arranging liquid cooling pipes, arranging liquid cooling plates, or immersing the entire battery module in a liquid cooling medium. Among them, immersion cooling has the significant advantage of fast heat dissipation rate.

[0003] However, immersion cooling still has some defects. For example, it is impossible to adjust the local parts of the battery module in real time during cooling, resulting in some parts of the battery module having high temperatures and some parts having low temperatures. This temperature difference will affect the normal use of the battery module and may cause safety risks in severe cases. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0082] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0083] The terms "comprises," "comprising," or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0085] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0086] In recent years, new energy vehicle models on the market have become increasingly intelligent and cost-effective. For example, the battery module is immersed in a liquid cooling medium for cooling. The heat dissipation method of the battery module is changed from solid indirect heat conduction to liquid convection, which can significantly improve the heat dissipation efficiency.

[0087] However, immersion cooling still has some defects. For example, it is impossible to adjust the local parts of the battery module in real time during cooling, resulting in some parts of the battery module having high temperatures and some parts having low temperatures. This temperature difference may cause the battery module to bulge or deform, which may cause safety risks in severe cases.

[0088] Based on the above problems, an embodiment of the present invention provides an immersion liquid cooling box that can solve the above problems, which will be described in detail below.

[0089] Please refer to Figure 1 and Figure 2 The immersion liquid cooling box includes: an outer shell 1, a partition 2 and an adjusting device 7. The partition 2 is arranged inside the outer shell 1. The partition 2 and the outer shell 1 enclose a first chamber 10 and a second chamber 11. The first chamber 10 and the second chamber 11 are both connected to the external liquid cooling medium. The partition 2 is provided with a plurality of through holes 20, and the plurality of through holes 20 can connect the first chamber 10 and the second chamber 11; the liquid cooling medium can flow between the first chamber 10 and the second chamber 11 through the through holes 20. When the battery module 6 is installed in the second chamber 11, the flow cross-sectional area of ​​the through hole 20 can be adjusted by the adjusting device 7 to change the flow rate of the liquid cooling medium in the second chamber 11, thereby changing the local temperature of the battery module 6 in the second chamber 11 and improving the uniformity of the temperature of each local part of the battery module 6.

[0090] In embodiment A, the outer shell 1 can be a box with one side open and the other sides closed. A cover plate 5 is provided on the open side of the box, and the cover plate 5 is detachably sealed and connected to the box. A partition plate 2 is arranged inside the box, and a through hole 20 is opened on the partition plate 2. The partition plate 2, the box and the cover plate 5 together divide the internal space of the box into a first chamber 10 and a second chamber 11. The through hole 20 penetrates the first chamber 10 and the second chamber 11.

[0091] At the same time, the first chamber 10 and the second chamber 11 are both connected to the outside of the box body. For example, a hole or groove is opened on the box body or the cover plate 5, and a liquid-cooling medium input pipe and a liquid-cooling medium output pipe are installed through the hole or groove. One end of the liquid-cooling medium input pipe or the liquid-cooling medium output pipe is sealed with the box body or the cover plate 5, and the other end of the liquid-cooling medium input pipe or the liquid-cooling medium output pipe is connected to a liquid-cooling medium input mechanism or a liquid-cooling medium recovery mechanism. The liquid-cooling medium input mechanism inputs the liquid-cooling medium into the first chamber 10 or the second chamber 11 through the liquid-cooling medium input pipe, and the liquid-cooling medium flows from the through hole 20 to the second chamber 11 or the first chamber 10, so that the first chamber 10 and the second chamber 11 are filled with liquid-cooling medium, and then the liquid-cooling medium cools the battery module 6 in the second chamber 11, and the liquid-cooling medium in the first chamber 10 can flow from another hole or groove on the box body or the cover plate 5 to the liquid-cooling medium output pipe, and then flow back to the liquid-cooling medium recovery mechanism, thereby forming a circulation loop.

[0092] Of course, in embodiment A, a seepage plate 3 may be provided on one side of the opening, and in this case, the cover plate 5 may not be provided. The seepage plate 3 is provided with a liquid inlet hole 30 and a liquid outlet hole 31, one end of the liquid inlet hole 30 is connected to the first chamber 10, and the other end of the liquid inlet hole 30 is connected to the liquid cooling medium input pipe, which is also connected to the liquid cooling medium input mechanism; similarly, one end of the liquid outlet hole 31 is connected to the second chamber 11, and the other end of the liquid outlet hole 31 is connected to the liquid cooling medium output pipe, which is also connected to the liquid cooling medium recovery mechanism.

[0093] In Example B, reference Figures 3 to 6 The outer shell 1 is surrounded by plates to form a closed annular belt, with openings on both sides. A cover plate 5 is provided at one opening, and the cover plate 5 is sealed and connected to the outer shell 1 . A seepage plate 3 is arranged at the other opening. The partition 2 is a U-shaped plate, and one side of the U-shaped plate opening is connected to the inner wall of the outer shell 1. The outer shell 1, the partition 2 and the cover plate 5 and the seepage plate 3 are together enclosed to form a first chamber 10 and a second chamber 11. The battery module 6 is installed in the second chamber 11. The seepage plate 3 is provided with a plurality of liquid inlet holes 30 and a plurality of liquid outlet holes 31. One end of the liquid inlet hole 30 is connected to the first chamber 10, and the other end of the liquid inlet hole 30 is connected to the liquid cooling medium input pipe, and the liquid cooling medium input pipe inputs the liquid cooling medium. One end of the liquid outlet hole 31 is connected to the second chamber 11, and the other end of the liquid outlet hole 31 is connected to the liquid cooling medium output pipe for outputting the liquid cooling medium. The liquid cooling medium enters the first chamber 10 from the liquid inlet hole 30 of the seepage plate 3, then enters the second chamber 11 from the through hole 20, and is then discharged from the second chamber 11 through the liquid outlet hole 31.

[0094] Of course, the liquid inlet hole 30 on the seepage plate 3 can also be connected to the second chamber 11, and the liquid outlet hole 31 can be connected to the first chamber 10. At this time, the flow direction of the liquid cooling medium is opposite to the aforementioned flow direction.

[0095] It should be noted that there are multiple through holes 20 on the partition 2, and the multiple through holes 20 can be evenly arranged in rows or rows at equal intervals, or can be arranged according to the actual heat generation of the battery module 6 during operation, with the through holes 20 densely arranged near the parts of the battery module 6 that generate more heat, and the through holes 20 sparsely arranged in other parts that generate less heat.

[0096] It should be noted that the through hole 20 on the partition 2 is close to one side of the cover plate 5, and the height of the through hole 20 from the seepage plate 3 is generally greater than the height of the battery module 6. This arrangement can ensure that the liquid cooling medium can completely submerge the battery module 6 to ensure the cooling effect.

[0097] refer to Figures 7 to 9 In order to make the overall liquid cooling box more concise, a flow channel plate 4 is arranged below the seepage plate 3. The liquid cooling medium is transported through the flow channel plate 4, which can save the connection of the liquid cooling medium input pipe to the liquid inlet hole 30 and the connection of the liquid cooling medium output pipe to the liquid outlet hole 31.

[0098] Specifically, the flow channel plate 4 is provided with a liquid inlet channel 40 and a liquid outlet channel 41. The liquid inlet channel 40 surrounds the outer circle of the flow channel plate 4, and the liquid outlet channel 41 is distributed in the middle of the flow channel plate 4. The liquid inlet channel 40 and the liquid outlet channel 41 are isolated from each other. The multiple liquid inlet holes 30 on the seepage plate 3 are also distributed around the outer circle, and the multiple liquid outlet holes 31 are distributed on the inner side of the seepage plate 3. The seepage plate 3 covers the flow channel plate 4, so that the multiple liquid inlet holes 30 are connected to the liquid inlet channel 40, and the multiple liquid outlet holes 31 are connected to the liquid outlet channel 41.

[0099] The seepage plate 3 is also provided with a liquid inlet pipe joint hole 32 and a liquid outlet pipe joint hole 33, the liquid inlet pipe joint hole 32 is connected to the liquid inlet flow channel 40, the liquid outlet pipe joint hole 33 is connected to the liquid outlet flow channel 41, the liquid inlet pipe joint hole 32 is connected to the liquid inlet pipe joint 34, the liquid outlet pipe joint hole 33 is connected to the liquid outlet pipe joint 35, and is connected to the external liquid cooling medium input pipe through the liquid inlet pipe joint 34, and is connected to the external liquid cooling medium output pipe through the liquid outlet pipe joint 35. The liquid inlet pipe joint 34 and the liquid outlet pipe joint 35 can be welded and fixed on the seepage plate 3, or can be threadedly connected to the seepage plate 3.

[0100] In embodiment B, the liquid outlet flow channel 41 includes multiple liquid outlet flow channels 41, which are distributed in parallel, each liquid outlet flow channel 41 corresponds to a column of liquid outlet holes 31 on the seepage plate 3, and the multiple liquid outlet flow channels 41 finally collect the liquid cooling medium to the liquid outlet pipe joint hole 33 for discharge.

[0101] It should be noted that the size and shape of the seepage plate 3 and the flow channel plate 4 are adapted to each other, and the joint portion of the seepage plate 3 and the flow channel plate 4 is sealed to prevent the liquid cooling medium in the liquid inlet channel 40 from mixing with the liquid cooling medium in the liquid outlet channel 41.

[0102] also, Fig. 9 The forms of the liquid inlet channel 40 and the liquid outlet channel 41 shown are only examples. In other embodiments, the liquid inlet channel 40 and the liquid outlet channel 41 may also be in other forms.

[0103] The cross-sectional shapes of the liquid inlet channel 40 and the liquid outlet channel 41 can be trapezoidal, rectangular, semicircular, inverted arched, or other shapes.

[0104] The depths of the liquid inlet channel 40 and the liquid outlet channel 41 should be kept consistent as much as possible, which is conducive to the uniform flow of the liquid cooling medium.

[0105] In Embodiment A and Embodiment B, the battery module 6 is installed in the second chamber 11 . In other embodiments, the battery module 6 may also be installed in the first chamber 10 .

[0106] In the embodiments A and B, the number of the battery module 6 is one. In other embodiments, the number of the battery module 6 may also be multiple.

[0107] The arrangement of the first chamber 10 and the second chamber 11 may be various. In other embodiments, the arrangement of the first chamber 10 and the second chamber 11 may be different from Figure 4 Other forms shown.

[0108] In Embodiment A and Embodiment B, the outer shell 1 and the partition 2 may be made of metal materials, such as aluminum, aluminum alloy, copper, titanium alloy, etc., or may be made of plastic materials or other materials, without limitation.

[0109] In Embodiment A and Embodiment B, a regulating device 7 is provided at each through hole 20 of the partition 2, and the flow cross-sectional area of ​​the through hole 20 is adjusted by the regulating device 7, thereby regulating the local flow of the liquid cooling medium.

[0110] The following is an exemplary description of the adjusting device 7. When using the various adjusting devices 7 exemplified below, one or more of them can be selected and arranged at the through hole 20. Of course, the various adjusting devices 7 exemplified below are only used as exemplary descriptions and are not used to limit the form of the adjusting device 7.

[0111] The embodiment of the present invention further provides a regulating device 7, comprising: an intercepting member 70 and a driving member 71, wherein the driving member 71 is used to drive the intercepting member 70 to move, and the intercepting member 70 can be used to block the through hole 20, thereby adjusting the flow cross-sectional area of ​​the through hole 20. When the intercepting member 70 blocks the through hole 20, it can block part of it or block it completely, and the intercepting member 70 can also move to a position where the through hole 20 can completely connect the first chamber 10 and the second chamber 11.

[0112] Preferably, the intercepting member 70 may be a plate, a block, or a rod. When the intercepting member 70 is a rod, the intercepting member 70 may be disposed in the through hole 20; in this embodiment, the intercepting member 70 is a flat plate disposed on the side wall of the partition 2; of course, when the intercepting member 70 is a block, the intercepting member 70 may be disposed in the through hole 20 or on the side wall of the partition 2.

[0113] The driving member 71 can be any one of a motor, a cylinder, an oil cylinder, and an expansion pack. When any one of the motor, the cylinder, and the oil cylinder is used, a temperature sensor can be used to be arranged near each through hole 20, and the temperature sensor is indirectly connected to the cylinder, the motor, and the oil cylinder for communication, and the measured temperature data is summarized and analyzed, and finally a cylinder, a motor, and an oil cylinder at a certain location are instructed to work, drive the interception member 70 to move, or block the through hole 20 to reduce the flow cross-sectional area of ​​the through hole 20, or move away from the through hole 20 to increase the flow cross-sectional area of ​​the through hole 20.

[0114] In the following embodiments, the driving members 71 are all expansion packs, which have the characteristics of thermal expansion and contraction or thermal contraction and cold expansion. The temperature change of the liquid cooling medium near the local part of the battery module 6 causes the expansion or contraction of the expansion pack, thereby automatically adjusting the flow of the liquid cooling medium in the local part. Moreover, the use of the expansion pack does not require the additional arrangement of other auxiliary components, saving manufacturing costs.

[0115] In the following embodiments, the expansion packs all have the property of thermal expansion and contraction. Specifically, the expansion packs are plastic bags with expandable substances such as hydrogen encapsulated inside. The expandable substances may also be solid substances, liquid substances or other gases.

[0116] The adjustment device 7 is explained in more detail below.

[0118] refer to Figures 10 to 13 The adjusting device 7 comprises an intercepting member 70, a driving member 71, an end cover 72 and a resilient member 73. The end cover 72 is connected to the partition plate 2 by screws, bolts or welding. The driving member 71 of this embodiment is an expansion bag, and the intercepting member 70 is a sliding plate.

[0119] A mounting groove 721 and a guide groove 722 are provided on one side of the end cover 72. The sliding plate, the expansion bag and the rebound member 73 are all accommodated in the mounting groove 721. A guide member 74 is provided in the guide groove 722. The guide member 74 is a pulley or a slider. The guide member 74 can slide along the guide groove 722. The guide member 74 is engaged with the sliding plate. When the sliding plate moves, it is guided by the guide member 74. The guide member 74 controls the moving direction of the sliding plate.

[0120] The end cap 72 is also provided with an opening slot 723, which is arranged opposite to the through hole 20, that is, the opening slot 723 can be partially or completely connected to the through hole 20. The opening slot 723 is located at the top of the end cap 72 and one side passes through the end cap 72. The opening slot 723 corresponds to the position of the through hole 20. The opening slot 723 and the through hole 20 are connected or blocked by the intercepting member 70. When the intercepting member 70 is removed for observation, the opening slot 723 and the through hole 20 are at least partially connected.

[0121] The expansion bag is arranged at the lower end of the sliding plate, and the rebound member 73 is arranged at the upper end of the sliding plate. A square hole can be provided on the sliding plate, and the square hole can movably connect the through hole 20 and the opening groove 723 . When the expansion pack expands due to heat, it pushes the sliding plate upward, so that the square hole on the sliding plate connects the opening groove 723 and the through hole 20. The distance that the expansion pack pushes the sliding plate upward due to expansion can control the flow cross-sectional area of ​​the square hole connecting the opening groove 723 and the through hole 20, thereby controlling the flow rate of the local liquid cooling medium. The higher the local temperature of the battery module 6, the higher the temperature of the liquid cooling medium there will be. The liquid cooling medium will transfer heat to the expansion pack. The more heat the expansion pack receives, the larger the expansion volume will be, so that the sliding plate is pushed upward until the square hole can completely connect the opening groove 723 and the through hole 20, so that the flow cross-sectional area is also larger, and the flow rate of the flowing liquid cooling medium is also larger, thereby achieving rapid cooling of the local area. When the local temperature has dropped, the expansion pack receives less heat from the liquid cooling medium near the battery module 6. Accordingly, the expansion pack shrinks, the sliding plate moves downward, and the flow cross-sectional area of ​​the square hole connecting the through hole 20 and the opening groove 723 is correspondingly reduced, thereby reducing the local liquid cooling medium flow rate to avoid the temperature being too low.

[0122] The thermal expansion and contraction characteristics of the expansion pack and the up and down movement of the sliding plate can be used to automatically adjust the temperature of each part of the battery module 6 without human intervention, which is efficient and convenient.

[0123] Of course, the square hole on the sliding plate can also be set as a slot shape, as long as the sliding plate can change the flow cross-sectional area of ​​the through hole 20 and the open slot 723 during the upward and downward movement.

[0124] During the upward movement of the sliding plate, the resilient member 73 is compressed. When the expansion pressure of the expansion bag decreases, the resilient member 73 returns to its original state to generate a rebound force. The combination of the gravity of the sliding plate and the rebound force of the resilient member 73 causes the sliding plate to move downward. The resilient member 73 in this embodiment is arranged across the opening groove 723, and the resilient member 73 does not block the through hole 20 when in contact with the partition 2. The resilient member 73 in this embodiment can be a rubber pad or made of other elastic materials.

[0125] In this embodiment, the resilient member 73 is fixed on the partition plate 2 . Of course, when the end cover 72 does not move, the resilient member 73 may also be directly fixed on the end cover 72 .

[0126] A heat conduction groove 724 is also provided on the end cover 72. The position of the heat conduction groove 724 corresponds to the position of the expansion pack. The heat conduction groove 724 is used to reduce the heat transfer distance between the expansion pack and the liquid-cooling medium in the second chamber 11, so that the expansion pack can more sensitively sense the temperature change of the liquid-cooling medium at a local position in the second chamber 11, and then sensitively adjust the flow rate of the liquid-cooling medium at that location.

[0129] Compared with the first embodiment, the difference of this embodiment is that the end cover 72 is changed in shape. In this embodiment, the upper part of the end cover 72 is cut off, so that the square hole on the sliding plate is completely exposed at room temperature, and the square hole can increase the flow rate of the liquid cooling medium when moving upward.

In this embodiment, a plurality of pin holes are still provided on the end cover 72, and the pin holes are the same as the pin holes in the third embodiment.

[0137] Compared with the third embodiment, the overall shape of the sliding plate in this embodiment is the same as that of the sliding plate in the third embodiment, but the sliding plate in this embodiment is provided with a plurality of transverse grooves, and the long sides of the square holes provided on the sliding plate in this embodiment are arranged in the transverse direction.

[0138] In this embodiment, the sliding plate is transversely arranged in the mounting groove 721 of the end cover 72, the expansion bag is embedded in the end groove of the sliding plate, and the rebound member 73 is arranged at the other end of the sliding plate.
