Description

Technical Field

[0001] This invention relates to the field of battery heat dissipation technology, and more particularly to a heat dissipation structure for a solid-state battery pack. Background Technology

[0002] In practical applications of solid-state battery packs, especially in large-capacity power battery packs and high-power energy storage systems, the continuous charging and discharging of batteries generates a large amount of heat. Existing heat dissipation technologies mostly employ indirect contact solutions using air cooling or liquid cooling plates. These solutions have long heat conduction paths and high thermal resistance, preventing heat from being quickly dissipated from the battery cell surface and easily causing temperature accumulation inside the battery pack. Furthermore, traditional fixing methods struggle to balance clamping force with heat dissipation requirements, making the battery prone to loosening under vibration, further impacting thermal contact efficiency.

[0003] Inspired by the constraints of compact space and weight, existing structures generally lack active heat dissipation mechanisms for each individual battery cell. Conventional liquid cooling channels are often located outside the battery module, making it impossible to achieve precise temperature control of individual battery cells. In addition, passive heat dissipation designs rely on ambient temperature differences, and their heat dissipation capacity drops sharply under high temperature or high load conditions, leading to battery pack performance degradation or even the risk of thermal runaway.

[0004] Therefore, existing technologies mainly face three problems: First, the battery fixing structure and heat dissipation function are disconnected, making it difficult to achieve reliable fastening and efficient heat conduction simultaneously in a limited space; second, there is a lack of active circulation heat dissipation methods integrated into the battery body, resulting in insufficient heat dissipation efficiency and uniformity; and third, traditional reciprocating drive mechanisms are prone to transmission instability in vibration environments, affecting the long-term operational reliability of the heat dissipation system. Summary of the Invention

The arc-shaped elastic plate is integrally formed with the heat dissipation ring, and an arc-shaped cavity is formed between the arc-shaped elastic plate and the arc-shaped groove.

[0010] Preferably, the interior of the arc-shaped cavity is filled with an appropriate amount of condensing circulating liquid, and the remaining part of the heat dissipation convex ring is provided with several equidistant semi-annular flow channels, the two ends of which are respectively connected to the two sides of the arc-shaped cavity.

[0012] Preferably, the actuating mechanism includes a reciprocating bevel gear and a pair of driven bevel gears. The reciprocating bevel gear is fixedly sleeved on the inner end of the reciprocating shaft. Driven bevel gears are fixedly sleeved on the opposite ends of a pair of driven shafts located in the same axial direction. The reciprocating bevel gear is located between the pair of driven bevel gears and meshes with the pair of driven bevel gears.

[0013] Preferably, each of the rectangular horizontal frames is fixed with a horizontally arranged I-shaped slide rail inside, and the front and rear sides of the fixing plate are fixed with a number of U-shaped brackets arranged at equal intervals.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1.

In actual scenarios with frequent vibration, this structure ensures smooth transmission and timely response, provides a continuous and reliable power input for the heat dissipation system, and maintains the long-term efficient heat dissipation of the solid-state battery pack.

[0019] In summary, this invention achieves a unified solution for fixing, heat conduction, and heat dissipation in practical solid-state battery pack applications through the coordinated operation of multiple components.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1: This example provides a heat dissipation structure for a solid-state battery pack. See [link / reference] Figures 1 to 9 Specifically, the mounting includes a fixing plate 100, with a pair of parallel horizontal plates 101 positioned above and below the fixing plate 100. A pair of symmetrically arranged side plates 102 are fixedly engaged on both sides of the fixing plate 100. The upper and lower ends of each side plate 102 are respectively fixedly engaged on the pair of horizontal plates 101. The fixing plate 100 and the pair of horizontal plates 101 cooperate to form the installation space for the battery body 300. Several battery bodies 300 arranged at equal intervals are fixedly installed between the fixing plate 100 and the pair of horizontal plates 101, ensuring the stability and consistency of the battery body 300 installation. Each battery body... Each battery body 300 is fixedly fitted with a pair of heat dissipation protrusions 301. The heat dissipation protrusions 301 are directly fixed and attached to the battery body 300 to quickly conduct the heat generated by the battery body 300. Every three adjacent battery bodies 300 form a group of structures arranged in an equilateral triangle. Each group of battery bodies 300 is provided with a pair of coaxially arranged triangular actuating disks 207. The three ends of each triangular actuating disk 207 slide against the corresponding heat dissipation protrusions 301. By rotating back and forth alternately, the heat dissipation protrusions 301 are squeezed and actuated, driving the flow of condensate circulation liquid. The top and bottom surfaces of the fixed plate 100 are fixed with several staggered fixed lugs 200 on both the front and rear sides, which provide rotational support for the reciprocating shafts 201. A reciprocating shaft 201 is rotatably inserted through the outer end of each fixed lug 200, and an actuating mechanism for driving a pair of triangular actuating discs 207 to rotate alternately is installed at the inner end of each reciprocating shaft 201. A pair of staggered rectangular horizontal frames 103 are slidably arranged on the front and rear sides of the fixed plate 100, and each rectangular horizontal frame 103 has... A meshing mechanism is installed to drive the reciprocating shaft 201 to reciprocate. The outer end of the reciprocating shaft 201 receives power through the meshing mechanism, and the inner end transmits power through the actuating mechanism, converting the reciprocating sliding of the rectangular horizontal frame 103 into its own reciprocating rotation, thus realizing power transmission. A pair of reciprocating mechanisms for driving the reciprocating sliding of the rectangular horizontal frame 103 are also installed alternately on the fixing plate 100. Under the drive of the reciprocating mechanism, the rectangular horizontal frame 103 drives the relevant components to reciprocate and slide, transmitting power to the reciprocating shaft 201.

[0023] It should be noted that: the upper and lower surfaces of the fixing plate 100 and the opposite surfaces of the pair of horizontal plates 101 are provided with a number of evenly arranged circular grooves 400, and each circular groove 400 is provided with a fixing component for limiting and fixing the end of the battery body 300. The fixing assembly includes an arc-shaped clamping plate 404 and a tension spring 406. The opening of the circular groove 400 has three circularly distributed L-shaped notches 401. Each L-shaped notch 401 is hingedly inserted with a hinge shaft 403. The outer end of each hinge shaft 403 is fixed with an arc-shaped clamping plate 404. The outer end of each arc-shaped clamping plate 404 has an arc-shaped notch 405. Each arc-shaped notch 405 fits against the end of the battery body 300 to form a stable clamping and fixing structure. Each L-shaped notch 401 has a tension spring 406 fixed inside. The outer end of each tension spring 406 is fixed to the arc-shaped clamp 404 on the corresponding side. A spiral groove 402 is opened on the inner wall of the circular groove 400, and a heat dissipation hole 407 is opened in the middle of the spiral groove 402, so as to realize the simultaneous fixation and heat dissipation.

[0024] The working principle of this embodiment is as follows: When the battery body 300 is installed, its two ends are respectively inserted into the circular grooves 400, and the ends of the battery body 300 are tightly fitted with the spiral grooves 402. The tension spring 406 will release the tension and apply a force to the arc-shaped clamping plate 404 to swing outward along the hinge axis 403. This will drive the three arc-shaped clamping plates 404 to move towards the ends of the battery body 300 simultaneously, so that the arc-shaped notch 405 can accurately fit and press against the outer circumferential surface of the ends of the battery body 300, forming a stable clamping and fixing structure to ensure that the battery body 300 is stable in the installation space. A certain flow gap is maintained between the spiral grooves 402 and the ends of the battery body 300 to quickly conduct heat to the ends. This, together with the heat dissipation holes 407, forms a heat dissipation channel to efficiently dissipate the heat generated at the ends of the battery body 300, achieving simultaneous fixing and heat dissipation. A pair of reciprocating mechanisms drive a pair of rectangular horizontal frames 103 to slide back and forth along a set trajectory. During the sliding process, the rectangular horizontal frames 103 form a transmission engagement with the reciprocating shaft 201 through a meshing mechanism, thereby driving the reciprocating shaft 201 to rotate back and forth. When the reciprocating shaft 201 rotates back and forth, the toggle mechanism moves synchronously, driving a pair of triangular toggle discs 207 between each battery body 300 to rotate alternately. Therefore, the alternating rotation of the triangular dial 207 will create a periodic squeezing and turning effect on the heat dissipation ring 301, thereby driving the condensation circulating fluid filled inside the heat dissipation ring 301 to flow faster; and because the heat dissipation ring 301 is directly fixed to the battery body 300, the heat generated by the battery body 300 during operation will be quickly conducted to the heat dissipation ring 301, and then the heat will be efficiently carried away by the flowing condensation circulating fluid, ultimately achieving continuous heat dissipation of the battery body 300.

[0025] Example 2: Based on Example 1, this example optimizes the internal structure of the heat dissipation ring 301 and refines the bevel gear transmission structure of the actuating mechanism, thus solving the problems of insufficient condensate circulation efficiency and poor heat dissipation uniformity, further improving the heat dissipation performance of the solid-state battery pack. It also includes: In the specific implementation process, such as Figure 8 and Figure 9 As shown, the protruding part of the heat dissipation ring 301 has an arc-shaped groove 302. An arc-shaped elastic plate 304 is fixed at the opening of the arc-shaped groove 302. The arc-shaped elastic plate 304 is integrally formed with the heat dissipation ring 301. An arc-shaped cavity is formed between the arc-shaped elastic plate 304 and the arc-shaped groove 302. The arc-shaped groove 302 and the arc-shaped elastic plate 304 cooperate to form an arc-shaped cavity, providing a basic space for the storage and flow of condensate circulation liquid. The arc-shaped elastic plate 304 can undergo elastic deformation under the pressure of the triangular actuating disk 207. The deformation generates pressure changes, driving the condensate circulation liquid in the arc-shaped cavity to flow. The interior of the arc-shaped cavity is filled with an appropriate amount of condensing circulating liquid. The remaining part of the heat dissipation convex ring 301 is provided with several equidistantly arranged semi-annular flow channels 303. The semi-annular flow channels 303 provide channels for the condensing circulating liquid to circulate, ensuring that the condensing circulating liquid flows evenly in the heat dissipation convex ring 301 and improving the heat dissipation uniformity. The two ends of the semi-annular flow channels 303 are respectively connected to the two sides of the arc-shaped cavity. The arc-shaped cavity is the starting and converging space for the flow of condensing circulating liquid. The pressure change pushes the condensing circulating liquid into the semi-annular flow channels 303. The condensing circulating liquid efficiently carries away the heat of the battery body 300 conducted by the heat dissipation convex ring 301 through the flow, realizing the heat dissipation function. Each triangular actuating disk 207 has a fixed sleeve 206 fixedly inserted in the middle. The fixed sleeve 206 is used to connect the triangular actuating disk 207 and the driven shaft 205 to realize the synchronous rotation of the driven shaft 205 and the triangular actuating disk 207. Each fixed sleeve 206 has a through driven shaft 205 fixedly inserted in the middle. The driven shaft 205 is used to receive the power of the driven bevel gear 204 and transmit it to the fixed sleeve 206 and the triangular actuating disk 207. The driven shaft 205 located adjacent to the fixed plate 100 is rotatably inserted on the fixed plate 100, and the driven shaft 205 located adjacent to the horizontal plate 101 is rotatably inserted on the horizontal plate 101. The actuating mechanism includes a reciprocating bevel gear 203 and a pair of driven bevel gears 204. The reciprocating bevel gear 203 is fixedly sleeved on the inner end of the reciprocating shaft 201. The driven bevel gears 204 are fixedly sleeved on the opposite ends of a pair of driven shafts 205 located in the same axial direction. The reciprocating bevel gear 203 is located between the pair of driven bevel gears 204 and meshes with the pair of driven bevel gears 204. The reciprocating bevel gear 203 is used to convert the reciprocating rotation of the reciprocating shaft 201 into the forward and reverse reciprocating rotation of the pair of driven bevel gears 204, thereby realizing the conversion and transmission of power direction.

[0026] The working principle of this embodiment is as follows: When the reciprocating shaft 201 reciprocates under the drive of the meshing mechanism, it will drive the reciprocating bevel gear 203 to rotate synchronously. Therefore, the rotation of the reciprocating bevel gear 203 will mesh and drive a pair of driven bevel gears 204 to reciprocate in opposite directions, thereby driving the driven shaft 205 to reciprocate synchronously. When the driven shaft 205 rotates, it will drive the fixed sleeve 206 and the triangular actuating disk 207 to rotate synchronously. During the rotation of the triangular actuating disk 207, its three ends alternately abut against the arc-shaped elastic plate 304 and form a periodic squeezing effect on the arc-shaped elastic plate 304. The squeezing action causes a pressure change in the condensing circulating liquid filled in the arc-shaped cavity, which in turn drives the condensing circulating liquid to circulate along several semi-annular flow channels 303, and finally forms a stable reciprocating condensing circulating liquid flow in the heat dissipation protrusion ring 301. Since the heat dissipation protrusion ring 301 is directly fixed and attached to the battery body 300, the heat generated by the operation of the battery body 300 can be quickly conducted to the heat dissipation protrusion ring 301, and then the heat is efficiently and evenly carried away by the continuously circulating condensing circulating liquid, so as to achieve efficient heat dissipation of the battery body 300.

[0027] Example 3: Based on Example 2, this example adds a guiding structure consisting of an I-shaped slide rail 105 and a U-shaped bracket 106, a reciprocating drive structure consisting of a motor 108, a Reichelk triangle 109, and a rectangular frame 107, and a meshing mechanism where the rack segment 104 engages with the reciprocating gear 202. This solves the problems of insufficient sliding stability of the rectangular frame 103 and poor reciprocating transmission accuracy, further ensuring the efficient and stable operation of the heat dissipation system. It also includes: In the specific implementation process, such as Figure 1 and Figure 2 As shown, each rectangular frame 103 is fixed with a horizontally arranged I-shaped slide rail 105 inside. The front and rear sides of the fixing plate 100 are fixed with a number of U-shaped brackets 106 arranged at equal intervals. Each I-shaped slide rail 105 is slidably engaged in the number of U-shaped brackets 106 located on the same side. The I-shaped slide rail 105 provides precise guidance for the reciprocating sliding of the rectangular frame 103 and ensures the smoothness of the sliding. The meshing mechanism includes a reciprocating gear 202 and a rack segment 104. The outer end of each reciprocating shaft 201 is fixedly fitted with a reciprocating gear 202. Several rack segments 104 are fixedly arranged at equal intervals on the upper and lower sides of the rectangular frame 103. Each rack segment 104 is meshed with the adjacent reciprocating gear 202 to convert the reciprocating sliding of the rectangular frame 103 into the reciprocating rotation of the reciprocating gear 202, thereby realizing power transmission. The reciprocating mechanism includes a motor 108 and a rectangular frame 107. A pair of staggered square slots are respectively opened on the front and rear sides of the fixing plate 100. A motor 108 with the output end facing out is fixedly installed inside each square slot. An eccentrically arranged Reilly triangle 109 is fixedly sleeved on the end of the motor shaft of each motor 108. The motor 108 is used to drive the Reilly triangle 109 to rotate. A rectangular frame 107 is fixed on one side of the rectangular frame 103. A Reilly triangle 109 is located inside the rectangular frame 107, and the outer surface of the Reilly triangle 109 is slidably connected to the inner wall of the rectangular frame 107. The Reilly triangle 109 rotates to form a periodic limiting drive on the rectangular frame 107, converting the rotational motion of the motor 108 into the reciprocating linear motion of the rectangular frame 107.

[0028] The working principle of this embodiment is as follows: First, the motor 108 is started, and the motor shaft of the motor 108 drives the Reilly triangle 109 to rotate synchronously; during the rotation of the Reilly triangle 109, it will form a periodic limiting drive effect on the rectangular frame 107, thereby driving the rectangular frame 107 together with the rectangular horizontal frame 103, several rack segments 104 and the I-shaped slide rail 105 to slide smoothly back and forth along several U-shaped brackets 106; When the rectangular horizontal frame 103 slides, the rack segment 104 on it meshes with the reciprocating gear 202, thereby driving the reciprocating shaft 201 to rotate stably. Subsequently, through the sequential transmission of the reciprocating bevel gear 203, driven bevel gear 204, driven shaft 205, fixed sleeve 206, and triangular dial 207, the circulation of the condensate in the heat dissipation ring 301 and the efficient heat dissipation of the battery body 300 are finally achieved. The subsequent heat dissipation transmission logic is consistent with that of Embodiment 2.
