Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] See Figure 1-4As shown, this embodiment provides a high-efficiency liquid cooling structure, including: a battery housing 100; a plurality of battery modules 110, which are evenly arranged in the horizontal and vertical directions; a fixing component disposed on the outside of the battery modules 110; a connecting component disposed between two fixing components, with both ends of the connecting component connected to two adjacent fixing components respectively; a first liquid cooling component disposed on the outside of the fixing components; and a second liquid cooling component disposed between two adjacent rows of battery modules 110.

[0043] It is understood that the high-efficiency liquid cooling structure provided in this embodiment achieves efficient heat dissipation for the battery module 110 by setting up a battery housing 100, a battery module 110, a fixing component, a connecting component, a first liquid cooling component, and a second liquid cooling component. The fixing component not only stabilizes the position of the battery module 110 but also provides a foundation for the installation of the liquid cooling component. The connecting component further strengthens the connection between the fixing components, improving the stability of the entire heat dissipation structure. The first liquid cooling component effectively dissipates heat from the side of the battery module 110 through a spirally arranged first liquid cooling pipe 141 on the side of the second frame 122 and a snap-fit ​​design with the groove 12211. Simultaneously, the series design of the first liquid cooling pipes 141 allows the coolant to circulate among multiple battery modules 110, improving heat dissipation efficiency. The second liquid cooling component dissipates heat from the top and bottom of the battery module 110 through a liquid cooling plate 151 disposed between two adjacent rows of battery modules 110, and a second liquid cooling pipe 152 and a third liquid cooling pipe 153 arranged vertically. This design not only increases the heat dissipation area but also allows the coolant to circulate throughout the battery pack, further improving heat dissipation efficiency.

[0044] Specifically, the fixing component includes: a first frame 121, which is sleeved on the outside of the battery module 110; and a second frame 122, which is disposed on the outside of the first frame 121. The first frame 121 and the second frame 122 are connected by a connecting rod 123. Both the first frame 121 and the second frame 122 are hollow frames.

[0045] Understandably, the hollow design of the first frame 121 and the second frame 122 not only reduces the weight of the entire heat dissipation structure but also provides space for the internal liquid cooling pipes. The first frame 121 is made of high-strength, lightweight materials, such as aluminum alloy, ensuring the stability and durability of the fixing components.

[0046] Specifically, the second frame 122 includes: two rectangular frames, each pair of rectangular frames forming a group, and each group of rectangular frames being arranged opposite each other in the vertical direction; four first vertical rods 1221, which are arranged vertically at the four corners of each group of rectangular frames, and the two ends of each first vertical rod 1221 are connected to each group of rectangular frames respectively; wherein, the cross-section of the first vertical rod 1221 is L-shaped.

[0047] Understandably, the L-shaped first vertical bar 1221 design not only enhances the structural strength of the second frame 122 but also provides support for the spiral arrangement of the first liquid cooling pipe 141. The combination of each set of rectangular frames and the four first vertical bars 1221 forms a stable frame system, effectively fixing the position of the battery module 110 and preventing displacement or vibration during operation. Furthermore, the L-shaped first vertical bar 1221 can also form a good fit with the first liquid cooling pipe 141, ensuring smooth flow of coolant within the pipe and further improving heat dissipation efficiency.

[0048] Specifically, each first vertical rod 1221 has several grooves 12211 along the vertical direction.

[0049] Specifically, the connecting components include: a plurality of horizontal bars 131, each horizontal bar 131 being arranged horizontally between two adjacent first vertical bars 1221, and the two ends of each first vertical bar 1221 being fixedly connected to the two adjacent first vertical bars 1221; and a plurality of second vertical bars 132, each second vertical bar 132 being arranged vertically between two adjacent rectangular frames, and the two ends of each second vertical bar 132 being connected to the two adjacent rectangular frames.

[0050] Understandably, the design of the horizontal bar 131 and the second vertical bar 132 not only enhances the connection strength between the fixing components but also provides additional support for the entire heat dissipation structure. The horizontal bar 131 connects two adjacent first vertical bars 1221 in the horizontal direction, effectively fixing the battery module 110 horizontally and preventing horizontal displacement during operation. The second vertical bar 132 connects two adjacent rectangular frames in the vertical direction, further enhancing the vertical stability of the entire heat dissipation structure. This design not only improves the overall stability of the heat dissipation structure but also helps maintain the stability and consistency of the battery module 110 during operation, thereby extending battery life and improving heat dissipation efficiency.

[0051] Specifically, the first liquid cooling assembly includes: a plurality of first liquid cooling pipes 141, each of which is spirally arranged in the vertical direction on the side of each second frame 122, and the first liquid cooling pipe 141 is engaged with the groove 12211. The first liquid cooling pipe 141 includes a first water inlet end 1411 and a first water outlet end 1412; wherein, in each row of battery modules 110, the first water outlet end 1412 of the current first liquid cooling pipe 141 is connected to the first water inlet end 1411 of the next first liquid cooling pipe 141.

[0052] Understandably, the spiral arrangement of the first liquid cooling pipe 141 not only increases the heat dissipation area but also makes the flow of coolant within the pipe more uniform, thereby improving heat dissipation efficiency. Each first liquid cooling pipe 141 is snapped into the second frame 122 via a groove 12211. This design not only simplifies the installation process but also ensures the stability of the first liquid cooling pipe 141 during operation. Furthermore, the series connection design between the first liquid cooling pipes 141 allows the coolant to circulate among multiple battery modules 110, further improving heat dissipation efficiency. The design of the first water inlet 1411 and the first water outlet 1412 facilitates the input and output of coolant, making the entire heat dissipation structure easier to maintain and manage.

[0053] Specifically, a heat-conducting layer 160 is provided between each first liquid cooling pipe 141 and each battery module 110.

[0054] Understandably, the thermally conductive layer 160 effectively improves the heat transfer efficiency between the battery module 110 and the first liquid cooling pipe 141. The thermally conductive layer 160 can be made of a material with high thermal conductivity, such as copper or aluminum, to ensure that heat can be quickly transferred from the battery module 110 to the first liquid cooling pipe 141. This design not only accelerates heat dissipation but also makes the heat dissipation structure more efficient and reliable.

[0055] Specifically, the second liquid cooling assembly includes: a liquid cooling plate 151, horizontally disposed between two adjacent rows of battery modules 110, with a second water inlet 1511 and a second water outlet 1512 respectively disposed at both ends of the liquid cooling plate 151; and a second liquid cooling pipe 152, vertically disposed inside the battery housing 100, located on the side of the second water inlet 1511 near the battery housing 100, with the top end of the second liquid cooling pipe 152 extending out of the battery housing 100 and the bottom end of the second liquid cooling pipe 152 closed; wherein, the second liquid cooling pipe 152... 52 is connected to the first water inlet 1411 and the second water inlet 1511 on the side near the battery box 100; the third liquid cooling pipe 153 is arranged vertically inside the battery box 100 and is located on the side of the second water outlet 1512 near the battery box 100, the bottom end of the third liquid cooling pipe 153 extends out of the battery box 100, and the top end of the second liquid cooling pipe 152 is closed; wherein, the third liquid cooling pipe 153 is connected to the first water outlet 1412 and the second water outlet 1512 on the other side near the battery box 100.

[0056] Understandably, the second liquid cooling assembly achieves comprehensive heat dissipation from the top and bottom of the two adjacent rows of battery modules 110. The liquid cooling plate 151 is horizontally positioned between the two adjacent rows of battery modules 110, directly absorbing the heat generated by the battery modules 110. The design of the second water inlet 1511 and the second water outlet 1512 facilitates the input and output of coolant. The second liquid cooling pipe 152 and the third liquid cooling pipe 153 are vertically positioned inside the battery housing 100, respectively connected to the second water inlet 1511 and the second water outlet 1512, forming a circulating flow path for the coolant within the battery pack. This design not only improves heat dissipation efficiency but also makes the entire heat dissipation structure more compact and efficient. Furthermore, the top and bottom ends of the second liquid cooling pipe 152 and the third liquid cooling pipe 153 extend out of the battery housing 100, facilitating connection and management with external cooling systems.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
