Description

Technical Field

[0001] The present invention relates to the field of battery thermal management technology, and in particular to a battery heat pipe system for battery replacement. Background Art

[0002] As people's environmental awareness gradually increases, the penetration rate of electric vehicles is getting higher and higher, but the charging time of electric vehicles is one of the important factors restricting the popularization of electric vehicles. In order to shorten the charging time of electric vehicles, people have developed swap batteries. When the battery is low, electric vehicles only need to go to the swap station to replace the fully charged battery to continue driving. During the operation of the swap battery, the swap battery will emit heat. At this time, it is necessary to transfer the heat emitted by the battery to the outside through heat exchange to achieve the purpose of protecting the battery. Currently, coolant is usually circulated in the swap battery to achieve the purpose of dissipating heat for the battery. However, since the flow direction and flow path of the coolant in the swap battery are fixed, and the coolant absorbs the heat emitted by the swap battery during its flow in the battery, the temperature of the coolant will gradually increase during its flow in the swap battery, resulting in different cooling effects of the coolant on the swap batteries at different positions on its flow path, affecting the service life of the swap battery.

[0039] Please refer to Figure 7-Figure 9 , a number of L-shaped parts 12 that are equidistant and symmetrically distributed are slidably connected in the diverter plate 3, the number of L-shaped parts 12 is twice the number of cooling channels 303, a tension spring is fixedly connected between the lower side of the L-shaped part 12 and the adjacent diverter plate 3, the opposite sides of the adjacent and symmetrically distributed L-shaped parts 12 of the same cooling channel 303 are all slidably connected with the limiting parts 13 on the upper and lower limit positions, a spring is fixedly connected between the upper side of the limiting part 13 and the adjacent L-shaped part 12, the limiting part 13 is limitedly matched with the adjacent diverter block 8, the limiting part 13 is extrusion-matched with the adjacent transmission part 9, so as to prevent the transmission part 9 from contacting the adjacent power part 10, the elastic coefficient of the adjacent tension spring of the L-shaped part 12 is greater than the elastic coefficient of the adjacent spring of the limiting part 13, and the elastic coefficient of the adjacent spring of the limiting part 13 is greater than the elastic coefficient of the elastic sheet on the extrusion block 11.

[0040] Please refer to Figure 7-Figure 9The left and right sides of the lower part of the cooling channel 303 are fixedly connected with mounting frames 14, and two slow-flow holes 141 are arranged on the mounting frames 14. The opposite sides of the mounting frames 14 symmetrically distributed in the same cooling channel 303 are sealed and slidably connected with trigger members 15, and the trigger members 15 are sealed and slidably connected with the adjacent cooling channel 303.

[0041] Please refer to Figure 10-12 The temperature control housing 4 is provided with a plurality of heat transfer cavities 161 which are equidistant and symmetrically distributed. The number of the heat transfer cavities 161 is twice the number of the cooling channels 303. The upper portion of the heat transfer cavity 161 is sealed and slidably connected with a transmission bar 16. The heat transfer cavity 161 is closer to the adjacent battery body 5 than the adjacent cooling channel 303. The lower portion of the heat transfer cavity 161 stores a phase change heat conductive material (the phase change material absorbs heat by changing its state). The transmission bar 16 is fixedly connected with a tensile member 17. The tensile member 17 is composed of a sealing rod fixedly connected to the adjacent transmission bar 16 and an elastic rope. The temperature control housing 4 is sealed and slidably connected with the sealing rod of the adjacent tensile member 17. The tensile members 17 adjacent to and symmetrically distributed in the same cooling channel 303 are commonly fixedly connected with an extrusion frame 18.

[0042] Please refer to Fig.11 and Fig.12 A T-shaped piece 19 is fixedly connected to the upper side of the L-shaped piece 12. The T-shaped piece 19 is extruded and matched with the adjacent extrusion frame 18 to drive the adjacent L-shaped piece 12 to move upward, releasing the limiting effect of the limiting piece 13 on the adjacent diverter block 8 and the adjacent transmission piece 9. The L-shaped piece 12 is limited and matched with the adjacent extrusion frame 18 to prevent the adjacent L-shaped piece 12 from moving upward.

[0043] During the operation of the battery replacement, the heat generated by the battery body 5 will be conducted to the adjacent temperature control shell 4, and then the coolant in the vehicle cooling system enters the liquid inlet pipe 6, and the coolant in the liquid inlet pipe 6 enters the two liquid inlet channels 301, and the coolant in the liquid inlet channel 301 enters the lower left part of the adjacent cooling channels 303, and the coolant rotates around the adjacent battery body 5 along the cooling channel 303 for one circle and then enters the adjacent discharge channel 302, and then the coolant in the discharge channel 302 re-enters the vehicle's cooling system through the discharge pipe 7. In the process of the coolant flowing along the cooling channel 303, the coolant absorbs the heat transferred from the battery body 5 to the adjacent temperature control shell 4, and indirectly reduces the temperature of the battery body 5 by lowering the temperature of the temperature control shell 4.

[0044] During the flow of the coolant in the liquid inlet channel 301, the coolant will drive several power parts 10 to rotate clockwise (later explained with a group of parts adjacent to the front side of the right battery body 5), and at the same time, the coolant in the liquid inlet channel 301 enters the cooling channel 303 through the first guide hole 801, and then the coolant in the cooling channel 303 continues to flow after passing through the two groups of blocking holes 151 in turn, and finally the coolant after circulating in the cooling channel 303 enters the discharge channel 302 through the second guide hole 802.

[0045] In the process of the coolant in the cooling channel 303 passing through the left-side blocking hole 151, the trigger member 15 will move to the left under the impact force of the coolant flow, and compress the spring adjacent to the left-side trigger member 15, and squeeze the coolant between the trigger member 15 and the adjacent mounting frame 14 out through the two slow flow holes 141, so as to control the movement speed of the trigger member 15. As the left-side trigger member 15 moves to the left, the left-side trigger member 15 gradually contacts the adjacent L-shaped member 12 and pushes the adjacent L-shaped member 12 to move upward, stretching the tension spring adjacent to the L-shaped member 12. The L-shaped member 12 drives the adjacent limit member 13 to move upward, causing the limit member 13 to lose contact with the diverter block 8 and the transmission member 9. Subsequently, the transmission member 9 moves forward under the extrusion of the elastic sheet of the rear extrusion block 11. At this time, the rear side of the transmission member 9 contacts the power member 10, and the power member 10 drives the transmission member 9 to move right through friction, and the transmission member 9 drives the diverter block 8 to move right.

[0046] During the rightward movement of the shunt block 8, the shunt plate 3 gradually blocks the second guide hole 802 and gradually releases the blockage of the third guide hole 803. At the same time, the first guide hole 801 is connected to the drainage channel 302. At this time, the coolant in the inlet channel 301 enters the right part of the lower side of the cooling channel 303 through the third guide hole 803, and enters the drainage channel 302 through the first guide hole 801 after circulating in the cooling channel 303 for one circle. At this time, the circulation direction of the coolant in the cooling channel 303 is opposite to the initial direction. While the above steps in this section are being performed, the shunt block 8 drives the two extrusion blocks 11 thereon to move. The front extrusion block 11 gradually approaches the adjacent unlocking groove 112 and contacts it first, and then the rear extrusion block 11 gradually approaches the adjacent unlocking block 111 and contacts it. As the diverter block 8 continues to move to the right, the unlocking slot 112 pushes the front extrusion block 11 downward, so that the elastic sheet of the front extrusion block 11 gradually contacts the front side of the transmission member 9 (at this time, the elastic sheets of the front and rear extrusion blocks 11 are in contact with the transmission member 9, but because the combined force of the elastic sheets of the front and rear extrusion blocks 11 on the transmission member 9 cannot overcome the static friction between the transmission member 9 and the diverter block 8, the transmission member 9 and the diverter block 8 remain relatively stationary at this time). As the diverter block 8 continues to move, the unlocking block 111 pushes the rear extrusion block 11 upward, so that the elastic sheet of the rear extrusion block 11 gradually loses contact with the rear side of the transmission member 9. At this time, the elastic sheet of the front extrusion block 11 overcomes the static friction between the transmission member 9 and the diverter block 8 and pushes the transmission member 9 to move backward.

[0047] When the circulation direction of the coolant in the third guide hole 803 changes, the coolant in the third guide hole 803 impacts the trigger member 15 on the right side, causing the trigger member 15 on the right side to move right, and repeating the above steps of moving the trigger member 15. At the same time, the trigger member 15 on the left side moves right and resets under the action of the adjacent spring, and a part of the coolant is drawn into between the trigger member 15 on the left side and the adjacent mounting frame 14 through the two adjacent slow-flow holes 141.

[0048] While the elastic sheet of the front extrusion block 11 pushes the transmission member 9 to move backward, the diverter block 8 contacts and is limited by the adjacent limiting member 13 on the right side. At the same time, the limiting member 13 limits the transmission member 9, preventing the transmission member 9 from continuing to move backward and contacting the power member 10. The above steps are then repeated until the trigger member 15 on the right side pushes the adjacent L-shaped member 12 to move, so that the right-side limiting member 13 releases the limiting of the diverter block 8 and the transmission member 9. At this time, the above steps are repeated in reverse so that the front side of the transmission member 9 contacts the power member 10 and moves to the left and resets under the drive of the power member 10. The above steps are repeated in sequence to intermittently change the flow direction of the coolant in the temperature control shell 4, thereby improving the uniformity of cooling the battery body 5, and thereby improving the overall cooling effect of the battery swap battery.

[0049] Under normal circumstances, with the circulation of the coolant, the temperature difference at various points around the battery body 5 is small. However, after the battery replacement battery is flooded or squeezed, the heat dissipated in the circumferential direction of the battery body 5 is uneven when working (hereinafter, the heat dissipated on the right side of the right battery body 5 is greater than the heat dissipated on the left side). When the heat on the right side of the battery body 5 is high and exceeds the set temperature (the set temperature is the maximum temperature of the battery when working normally), the phase change material in the heat transfer cavity 161 at the corresponding position on the right side of the temperature control shell 4 melts. At this time, the volume of the melted phase change material in the heat transfer cavity 161 increases and pushes the adjacent transmission bar 16 upward. The transmission bar 16 pulls the adjacent tensile member 17 upward, and the elastic rope of the tensile member 17 pulls the adjacent The extrusion frame 18 moves to the right, and at this time the elastic ropes of the two stretching members 17 are stretched, causing the extrusion frame 18 to move to the right and contact the L-shaped member 12 on the right and limit it. At the same time, the extrusion frame 18 contacts the T-shaped member 19 on the left and squeezes it upward, causing the T-shaped member 19 to pull the adjacent L-shaped member 12 and the adjacent limiting member 13 upward. If the diverter block 8 is located on the left at this time, as the limiting member 13 moves upward, the limiting member 13 on the left releases the limiting on the diverter block 8 and the transmission member 9, and then the diverter block 8 repeats the above steps to move to the right, and contacts the limiting member 13 during the right movement, squeezing the limiting member 13 on the right upward, compressing the spring adjacent to the limiting member 13, until the diverter block 8 moves to the right to the end, and the limiting member 13 limits the diverter block 8.

[0050] After the shunt block 8 moves to the right end, the circulation direction of the coolant in the cooling channel 303 is changed, so that the coolant passes through the right side of the temperature control shell 4 first, and the right side of the battery body 5 is cooled. Before the temperature of the right side of the battery body 5 is reduced, the extrusion frame 18 always limits the L-shaped member 12 on the right side, so that the limiting member 13 on the right side cannot release the limit on the shunt block 8, until the temperature of the right side of the battery body 5 is reduced to the normal temperature. At this time, the phase change material in the adjacent heat transfer cavity 161 solidifies again, so that the volume of the phase change material in the heat transfer cavity 161 is reduced, and the adjacent transmission bar 16 on the right side moves down and resets under the action of its elastic rope. At the same time, the extrusion frame 18 moves left and resets under the action of the elastic rope of the adjacent transmission bar 16 on the left side, so that the extrusion frame 18 releases the limit on the right L-shaped member 12, and at the same time, the T-shaped member 19 on the left side moves down and resets under the action of the adjacent tension spring of the adjacent L-shaped member 12, and then continues to repeat the above steps of moving the shunt block 8 left and right to cool the battery body 5.

[0051] The swap battery is usually fixed to the vehicle with bolts. During driving, due to bumps on the road, the swap battery is forced to bear the impact caused by the bumps. Over time, it is easy to cause damage to the connection between the swap battery and the vehicle, and even cause the swap battery to fall off directly.

[0052] Example 2: Based on Example 1, please refer to Figure 2 and Fig.13, also includes eight buffer cylinders 20 that are symmetrical and rectangular in distribution. The buffer cylinder 20 is fixedly connected to the outer shell 1. The battery body 5 is fixedly connected to four connecting columns 21 that are rectangular in distribution. The connecting columns 21 are sealingly and slidingly connected to adjacent buffer cylinders 20. A buffer member 22 is sealingly and slidingly connected to the middle and upper part of the buffer cylinder 20. The buffer member 22 is fixedly connected to the adjacent connecting columns 21. Two springs that are symmetrically distributed up and down are arranged between the buffer member 22 and the adjacent buffer cylinder 20. Damping fluid is stored in the buffer cylinder 20. The buffer member 22 is provided with a fan-shaped through hole 221. When the damping fluid flows through the fan-shaped through hole 221, the movement speed of the adjacent buffer member 22 is slowed down.

[0053] Please refer to Fig.14 The buffer member 22 is sealed and rotatably connected with a blocking fan plate 23, and an L-shaped guide groove 231 is provided in the buffer cylinder 20. The initial position of the buffer member 22 is used as a dividing line. The upper part of the L-shaped guide groove 231 is a straight part, and the lower part is an inclined part. The blocking fan plate 23 slides in the adjacent L-shaped guide groove 231 to block and cooperate with the adjacent fan-shaped through hole 221.

[0054] Please refer to Fig.14 and Fig.15 The buffer 22 is slidably connected with a one-way seal 24 in the upper and lower limit positions. A spring is fixed between the one-way seal 24 and the upper side of the adjacent buffer 22. The buffer 22 is provided with a reset through hole 241, which is sealed and cooperated with the adjacent one-way seal 24 to form a one-way valve for flow from top to bottom.

[0055] Please refer to Fig.14 and Fig.15 A wedge block 25 is fixedly connected to the upper side of the one-way seal 24, and a reset bar 26 is slidably connected to the buffer 22 in the front and rear limiting positions. The reset bar 26 is squeezed and matched with the adjacent wedge block 25 to reset the adjacent one-way seal 24 relative to the adjacent buffer 22. A trapezoidal guide groove 261 is provided in the buffer cylinder 20 for the adjacent reset bar 26 to slide. Initially, the highest point on the trapezoidal guide groove 261 is coplanar with the midpoint of the adjacent buffer 22.

[0056] When a vehicle encounters a pothole during driving, after the vehicle enters the first pothole (subsequent Fig.13Taking the buffer cylinder 20 as an example), the battery body 5 drives the four adjacent connecting columns 21 to move downward relative to the vehicle due to inertia, and the connecting columns 21 drive the adjacent buffer parts 22 to move downward, compressing the adjacent spring on the lower side of the buffer parts 22, and squeezing the damping fluid in the lower part of the buffer cylinder 20 into its upper part through the fan-shaped through hole 221. At the same time, the buffer part 22 drives the adjacent blocking fan plate 23 to move downward along the inclined part of the adjacent L-shaped guide groove 231, so that the blocking fan plate 23 rotates clockwise relative to the adjacent buffer part 22, and the blocking fan plate 23 gradually blocks the adjacent fan-shaped through hole 221. Since the connecting area of ​​the fan-shaped through hole 221 gradually decreases when moving downward, the resistance of the buffer part 22 to move downward gradually increases, thereby alleviating the impact on the battery body 5.

[0057] When the vehicle encounters continuous potholes, the buffer 22 cannot move up to the initial position in time after performing a buffering downward movement, resulting in a reduction in the buffer 22's buffering distance after encountering the second pothole. The solution is as follows: After the buffer 22 performs a buffering movement, the buffer 22 moves up under the action of the adjacent spring on its lower side. At this time, the damping fluid in the upper part of the buffer cylinder 20 pushes the one-way seal 24 to move downward relative to the adjacent buffer 22, and compresses the spring adjacent to the one-way seal 24, so that the one-way seal 24 releases the blockage of the adjacent reset through hole 241. This increases the flow area of ​​the damping fluid when the buffer 22 moves up, thereby increasing the speed at which the buffer 22 moves up and resets. While the buffer 22 moves up, the buffer 22 drives the adjacent blocking fan plate 23 to move up, and the blocking fan plate 23 rotates counterclockwise and gradually resets under the guidance of the adjacent L-shaped guide groove 231.

[0058] During the upward movement of the buffer 22, the buffer 22 drives the adjacent reset strip 26 to move upward along the adjacent trapezoidal guide groove 261. When the buffer 22 is about to be reset, the reset strip 26 moves to the end of the adjacent trapezoidal guide groove 261, and under the guidance of the trapezoidal guide groove 261, the reset strip 26 gradually moves into the adjacent buffer 22, so that the reset strip 26 squeezes the adjacent wedge block 25, and the wedge block 25 drives the adjacent one-way seal 24 to move upward and reset relative to the adjacent buffer 22 (during the upward movement of the buffer 22, the one-way seal 24 is equivalent to a one-way valve).

[0059] When the vehicle falls into the pit, the battery body 5 will move upward relative to the vehicle due to inertia. At this time, the battery body 5 drives the adjacent connecting column 21 to move upward, and the connecting column 21 drives the adjacent buffer 22 to move upward and compresses the spring adjacent to the upper side of the buffer 22. At this time, the buffer 22 squeezes the damping fluid in the upper part of the adjacent buffer cylinder 20 through the adjacent fan-shaped through hole 221 and flows into the lower part of the adjacent buffer cylinder 20. At the same time, the blocking fan plate 23 moves along the straight part of the adjacent L-shaped guide groove 231, keeping the connecting area of ​​the adjacent fan-shaped through hole 221 unchanged, and the upward movement tendency of the buffer 22 is alleviated by the spring and the damping fluid, thereby reducing the amplitude of movement of the battery body 5 in the outer shell 1.
