Description

[0001] The present invention belongs to the technical field of solid-state lithium batteries, in particular to a solid-state lithium battery with a heat dissipation structure. Background Art

[0002] Solid-state lithium batteries, due to their high energy density, superior safety, and long cycle life, are considered a core technology for electric vehicles and energy storage devices. However, they still face several key challenges in practical application, particularly heat dissipation. Solid-state lithium batteries generate significant heat during operation, especially under high-power charging and discharging conditions or in extreme environmental conditions. Uneven temperature distribution within the battery can lead to localized overheating, potentially causing thermal runaway, performance degradation, and even safety issues.

Currently, most of them are assembled into a shell, and the lithium batteries in the entire shell are cooled by air cooling or liquid cooling. However, this cooling method lacks specificity. If a lithium battery in the shell has an abnormally high temperature, it cannot be cooled quickly by the overall cooling method. At the same time, the heat dissipation efficiency of the remaining lithium batteries will be reduced, which will cause the lithium battery to be damaged due to being in a high temperature state for a long time.

[0034] like Figure 3-Figure 6 As shown, the air guide module includes: a first air inlet 21, the first air inlet 21 is arranged on the front side of the fixed shell 3, the front part of the fixed shell 3 is provided with two first air ducts 2101 distributed symmetrically on the left and right, the front part of the fixed shell 3 is provided with first air outlets 2102 distributed symmetrically on the left and right, the first air outlet 2102 is connected to the first air inlet 21 through the adjacent first air duct 2101, and the first air outlet 2102 is covered by the corresponding shielding plate 5; the second air outlet 22 is arranged on the rear side of the fixed shell 3, the rear part of the fixed shell 3 is provided with two second air ducts 2201 distributed symmetrically on the left and right, the rear part of the fixed shell 3 is provided with two second air inlets 2202 distributed symmetrically on the left and right, the second air inlet 2202 is connected to the adjacent second The air duct 2201 is connected to the second air outlet 22, and the second air inlet 2202 is covered by the corresponding baffle 5; a first air guide surface 2103 is provided at the connection point between the first air duct 2101 and the adjacent first air outlet 2102, and a second air guide surface 2203 is provided at the connection point between the second air duct 2201 and the adjacent second air inlet 2202. Both the first air guide surface 2103 and the second air guide surface 2203 are inclined surfaces. The first air guide surface 2103 is used to guide the wind in the adjacent first air duct 2101 to facilitate the discharge of wind from the corresponding first air outlet 2102, and the second air guide surface 2203 is used to guide the wind in the adjacent second air inlet 2202 to facilitate the wind to enter the corresponding second air duct 2201.

[0035] like Figure 3 、 Figure 4 and Figure 6-Figure 8 As shown, the driving mechanism includes: a mounting frame 31, which is fixed to the fixed shell 3, and the cross-section of the mounting frame 31 is L-shaped. The mounting frame 31 is fixed with two sliding shells 32 symmetrically distributed in the front and back; a first electromagnetic member 33, which is fixed between the symmetrically distributed sliding shells 32, and a magnetic member 34 is slidably connected in the sliding shell 32, and the magnetic member 34 is fixed to the corresponding baffle 5. The magnetic member 34 and the first electromagnetic member 33 are magnetically attracted to each other. After the first electromagnetic member 33 is energized, the first electromagnetic member 33 attracts the corresponding two magnetic members 34 through magnetic force, so that the two magnetic members 34 are close to each other. A first elastic member 35 is arranged between the magnetic member 34 and the adjacent sliding shell 32. The first elastic member 35 is a tension spring, which is used to drive the corresponding magnetic member 34 to reset.

[0036] The working principle of a solid-state lithium battery with a heat dissipation structure in this embodiment is as follows:

[0037] During the use of the present lithium battery, the external air cooling circulation system and the temperature sensor on the cover plate 2 are turned on, so that the cold air enters the mounting base 1 from the air inlet pipe 101, and then the cold air moves backward. Taking the front row of fixed shells 3 as an example, the cold air enters the corresponding first air duct 2101 through the three first air inlets 21, thereby cooling the lithium batteries 4 in the fixed shell 3. The cold air is then discharged along the corresponding first air outlet 2102 and flows into the gap between the two adjacent fixed shells 3, and then continues to move backward. During this process, part of the cold air in the gap between the two adjacent fixed shells 3 enters the corresponding second air duct 2201 through the second air inlet 2202, thereby cooling the lithium batteries 4 in the fixed shell 3. The cold air is then discharged from the fixed shell 3 through the second air outlet 22 and flows into the gap between the two corresponding fixed shells 3 on the rear side. As the cold air moves backward, the above process is repeated and passes through each row of fixed shells 3 in turn, while cooling the adjacent lithium batteries 4.

[0038] In the process of using cold air to cool down all the lithium batteries 4, the temperature sensor on the cover plate 2 is always in working condition and constantly detects the temperature of the lithium batteries 4 in the corresponding area. When a temperature sensor detects that the temperature of a lithium battery 4 has risen abnormally, the fixed shell 3 in the middle of the front row is described as an example. At this time, the temperature sensor detects the abnormal temperature rise and transmits the signal to the two first electromagnetic parts 33, so that the two first electromagnetic parts 33 start working. The first electromagnetic parts 33 attract the corresponding two magnetic parts 34, so that the corresponding two magnetic parts 34 are close to each other. The magnetic parts 34 stretch the adjacent first elastic parts 35, and the magnetic parts 34 drive the corresponding baffle 5 to move.

[0039] During the movement of the baffle plate 5, the two baffle plates 5 located on the same side of the fixed shell 3 move toward each other, and gradually release the obstruction of the corresponding first air outlet 2102 and the corresponding second air inlet 2202, respectively, thereby increasing the flow area of ​​the first air outlet 2102 and the second air inlet 2202, and facilitating the entry and discharge of cold air. Since the total amount of cold air entering the mounting base 1 remains unchanged, the amount of cold air flowing through the first air outlet 2102 and the second air inlet 2202 increases. At this time, the focus is on cooling the lithium battery 4 in the middle of the front row, so that the temperature of the lithium battery 4 drops rapidly. During the process, the cooling operation of the remaining lithium batteries 4 will not be stopped.

[0040] After the temperature sensor detects that the temperature of the lithium battery 4 has dropped to a normal level, the two first electromagnetic members 33 are turned off. The first electromagnetic members 33 lose their magnetic attraction to the corresponding magnetic members 34. The magnetic members 34 move under the action of the adjacent first elastic members 35 and block the first air outlet 2102 (second air inlet 2202) again, so that the air volume flowing through the fixed housing 3 returns to the initial level. If the temperature of a lithium battery 4 rises again and exceeds the normal range, the above operation is repeated to focus on cooling the lithium battery 4.

[0041] Example 2

[0042] Based on Example 1, this embodiment mainly provides a method for accelerating the heat dissipation rate of the fixed shell 3 to improve the safety of the lithium battery 4.

[0043] like Figure 4 、 Figure 8 and Figure 9 As shown, all the first air ducts 2101 and all the second air ducts 2201 on the fixed shell 3 are fixedly connected with the first air guide 41, and all the first air ducts 2101 and all the second air ducts 2201 on the fixed shell 3 are slidably connected with the second air guide 42. The first air guide 41 and the corresponding second air guide 42 are a group. The number shown in the figure is seven groups. All the first air guides 41 and all the second air guides 42 are staggered. The opposite sides of the first air guide 41 and the second air guide 42 are A plurality of grooves are provided, which are semi-hexagonal, that is, there are two vertical sides and two inclined sides. The first air guide 41 and the second air guide 42 are used to guide the wind entering the corresponding first air duct 2101 and the corresponding second air duct 2201, extend the path of the wind flow, increase the contact time between the wind and the fixed shell 3, and improve the efficiency of heat dissipation for the lithium battery 4; in the initial state, the semi-hexagonal grooves on the first air guide 41 and the corresponding semi-hexagonal grooves on the second air guide 42 are staggered (such as Figure 8 The state is shown), and the vertical side of the upper half hexagonal groove of the second air guide member 42 is aligned with one of the inclined sides on the corresponding upper half hexagonal groove of the second air guide member 42.

[0044] like Figure 6-Figure 9As shown, the fixed shell 3 is slidably connected to two drive frames 51 distributed symmetrically on the left and right. The drive frame 51 is composed of a U-shaped frame and a magnetic plate, and the magnetic plate is located on the lower side of the U-shaped frame. The drive frame 51 is fixedly connected to all the second air guide members 42 in the corresponding first air duct 2101 and the corresponding second air duct 2201. A second elastic member 52 is provided between the drive frame 51 and the fixed shell 3. The second elastic member 52 is a spring for driving the drive frame 51 to reset. A second electromagnetic member 53 is provided on the first electromagnetic member 33. The second electromagnetic member 53 and the magnetic plate of the corresponding drive frame 51 are magnetically attracted to each other. After the second electromagnetic member 53 is energized, the second electromagnetic member 53 drives the corresponding drive frame 51 to move by magnetic force, so that the drive frame 51 moves in the direction of the corresponding first electromagnetic member 33 and fits (as shown in FIG. Figure 9 shown).

[0045] The working principle of a solid-state lithium battery with a heat dissipation structure in this embodiment is as follows:

[0046] After the cold air enters the corresponding two first air ducts 2101 from the first air inlet 21, the cold air enters between the first air guide 41 and the corresponding second air guide 42, and passes through the semi-hexagonal grooves of the two in turn. During the process, the first air guide 41 and the corresponding second air guide 42 guide the cold air and make the cold air fully contact with the fixed shell 3, thereby improving the cooling effect of the lithium battery 4.

[0047] Based on the working principle of embodiment 1, when the front middle fixed shell 3 is cooled, the two second electromagnetic members 53 are turned on, and the second electromagnetic members 53 generate magnetic force and use the magnetic force to attract the corresponding driving frame 51, and the driving frame 51 moves closer to the corresponding second electromagnetic member 53. Figure 8 Taking the parts and directions shown in the figure as an example, the driving frame 51 moves to the left until it is in contact with the second electromagnetic member 53 (the second elastic member 52 accumulates force). During this process, the driving frame 51 drives all the second air guide members 42 thereon to move to the left, so that the vertical sides of the upper half hexagonal grooves of the second air guide members 42 are aligned with the top corners of the upper half hexagonal grooves of the corresponding first air guide members 41 (this state is shown in FIG. Figure 9 As shown), by driving all the second air guides 42 to move to the left, the distance between the vertical side of the upper half hexagonal groove of the first air guide 41 and the vertical side of the upper half hexagonal groove of the corresponding second air guide 42 is increased, reducing the obstruction to the cold air, facilitating the flow of cold air between the first air guide 41 and the corresponding second air guide 42, thereby quickly exchanging the cold air between the two, improving the cooling efficiency of the fixed shell 3, and then quickly cooling the lithium battery 4.

[0048] When the temperature of the lithium battery 4 returns to the appropriate range, the two second electromagnetic members 53 are turned off, thereby losing the attraction to the corresponding driving frame 51. The driving frame 51 is reset under the action of the adjacent second elastic member 52, and the driving frame 51 drives all the second air guide members 42 thereon to reset, so that the first air guide member 41 and the corresponding second air guide member 42 are restored to the initial state (as shown in FIG. Figure 8 shown).

[0049] Example 3

[0050] This embodiment is based on the second embodiment and is mainly aimed at reducing the heat dissipation of the lithium battery 4 when the lithium battery 4 is initially started during use in cold weather, and conserving the heat emitted by the lithium battery 4 so that the temperature of the lithium battery 4 quickly reaches the adapted temperature.

[0051] like Figures 8-10 As shown, two third electromagnetic members 61 are fixed to the bottom of the fixed shell 3 and are symmetrically distributed. The third electromagnetic members 61 and the corresponding driving frames 51 are magnetically attracted to each other. When the third electromagnetic members 61 are energized, the third electromagnetic members 61 attract the corresponding driving frames 51 through magnetic force, causing the driving frames 51 to move away from the corresponding first electromagnetic members 33 until the driving frames 51 are in contact with the corresponding third electromagnetic members 61 (as shown in FIG. Figure 10 Status).

[0052] The working principle of a solid-state lithium battery with a heat dissipation structure in this embodiment is as follows:

[0053] When the lithium battery is initially used, the temperature sensor is turned on to detect the temperature of the lithium battery 4. If the temperature of the outside world or a lithium battery 4 itself is lower than the appropriate range, the third electromagnetic member 61 is turned on, and the third electromagnetic member 61 generates magnetic force and uses the magnetic force to drive the corresponding driving frame 51 to move. Figure 8 Taking the parts and directions shown in the figure as an example, the driving frame 51 moves to the right and compresses the adjacent second elastic member 52. The driving frame 51 drives all the second air guide members 42 thereon to move. The second air guide members 42 move to the right and align the vertical sides of the upper half hexagonal grooves with the vertical sides of the upper half hexagonal grooves of the corresponding first air guide members 41 (as shown in FIG. Figure 10 As shown), at this time, the second air guide 42 and the corresponding first air guide 41 are in contact with each other, and the semi-hexagonal grooves on the second air guide 42 and the corresponding first air guide 41 are spliced ​​together to form a complete hexagon, and the hexagon and the fixed shell 3 together form a closed cavity. At this time, the heat released by the lithium battery 4 during initial operation will remain in the hexagonal cavity and cannot diffuse outward, thereby reducing the release of heat generated by the lithium battery 4, thereby achieving a heat preservation operation for the lithium battery 4, facilitating the increase of the temperature of the lithium battery 4 itself, and reducing the probability of damage.

[0054] When the temperature of the lithium battery 4 returns to the appropriate temperature range, the corresponding third electromagnetic member 61 is turned off. At this time, the driving frame 51 loses its magnetic attraction and is reset under the action of the adjacent second elastic member 52, so that the driving frame 51 returns to its initial position. The driving frame 51 drives all the second air guide members 42 thereon to return to their initial state, so that the first air guide member 41 and the corresponding second air guide member 42 return to their initial state (as shown in FIG. Figure 8 shown).
