Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery capacity dissipation, and in particular to a needle bed type lithium battery capacity dissipation device, a heat dissipation device and a system. Background Art

[0002] During the lithium battery capacity splitting process, the performance parameters of the battery cells directly affect the battery quality and service life, especially the safety and stability of battery use. Therefore, in order to ensure the consistency of the battery cell performance parameters, heat dissipation treatment is required during the battery capacity splitting process to maintain the temperature of the battery cell surrounding environment consistent and stable. It can be seen that heat dissipation treatment of the battery during the capacity splitting process is crucial to improving the safety and stability of the battery pack.

[0003] In the prior art, the conventional heat dissipation method for lithium battery capacity conversion is to use a constant temperature workshop to cool down the whole body, and control the whole temperature in the workshop within a certain set temperature range through air conditioning. The constant temperature workshop overall cooling method consumes a lot of energy for cooling, and the direct cooling cost is high. On the other hand, since the equipment continuously generates heat during operation, including the heat generated by the cell capacity conversion process and the heat generated by the equipment power supply itself, if the temperature around the cell needs to be maintained at 25°C, the set temperature of the constant temperature workshop must be reduced by at least 3°C. The low utilization rate of cold air and low heat dissipation efficiency further increase energy consumption and cost, and the heat dissipation plan of the constant temperature workshop also needs to consider cooling down the cell and the equipment power supply at the same time to control the average temperature of the workshop. On the other hand, the equipment is partially turned on or turned on successively during the production process. The temperature balance of the whole workshop is affected by the air duct layout, the cooling capacity and air volume of the air conditioner, which will cause the temperature around each device to be different, and the equipment ventilation design will also affect the temperature balance of each point on the same tray of batteries, and the actual temperature difference may even exceed ±3°C.

[0004] In summary, the existing lithium battery capacity splitting and heat dissipation solutions and capacity splitting equipment have the defects of high energy consumption, high operating cost, low heat dissipation efficiency and poor temperature balance, which directly affect the safety and stability of the battery.

[0023] like Figures 10 to 19 As shown, in this embodiment, the storage base 11 of the needle-bed type lithium battery capacity-fractionating and heat dissipation device is installed in several layers at equal intervals. In this embodiment, a four-layer storage base 11 is used, and is connected and fixed by four optical axes 12. Each layer includes two battery tray bodies 5, forming a needle-bed module frame 1; storage areas are formed between the storage bases 11, and cylinders 13 are fixedly installed on both sides of the top of each storage area; a horizontal air duct 21 is fixedly installed under the storage base 11; vertical air ducts 22 are fixedly installed on both sides of the horizontal air duct 21; a vertical air duct cover 2201 is installed on the outside of the vertical air duct 22, which can facilitate the inspection, maintenance and repair of the inside of the vertical air duct 22; a total horizontal air inlet duct 23 is fixedly installed on the top of the vertical air duct 22; an air inlet 213 is arranged on the top of the total horizontal air inlet duct 23, and the horizontal air duct 21, the vertical air duct 22, the vertical air duct cover 2201, and the total horizontal air inlet duct 23 together constitute an internal air duct 2.

[0024] In actual applications, a guide plate 231 is provided at a corresponding position below the air inlet 213 inside the total transverse air inlet duct 23, which is used to evenly divert the cold air input from the air inlet 213 to both sides. In order to make the delivery of the cold air smoother, guide plates 232 are provided at both ends of the total transverse air inlet duct 23 to quickly guide the cold air to the vertical air duct 22.

[0025] Specifically, four linear bearings 61 are fixedly installed on both sides of the floating support frame 6, and the four linear bearings 61 are matched and installed on the optical axis 12 in the storage area; a guide bar 63 is installed on the floating support frame 6; a tray positioning block 64 is installed on the rear side of the floating support frame 6; the guide bar 63 and the tray positioning block 64 jointly limit the freedom of the tray body 5 in the plane direction after it is loaded, so that the battery cells loaded on the tray body 5 correspond to the positions of the upper ejector body 31 and the lower ejector body 76.

[0026] In actual applications, battery height limiting hexagonal studs 62 are installed on both sides of the floating support frame 6; after the floating support frame 6 is installed on the needle bed module frame 1, it is supported by the elastic force of the support spring 16 to maintain the upward bouncing tendency, and at the same time is restricted by the floating upper limit hexagonal stud 14 and the floating lower limit hexagonal stud 15, so that it can only float up and down within a specific range.

[0027] The needle bed module described above, when the tray body 5 filled with batteries 55 is pushed into the storage position from the channel formed by the guide strip 63 on the floating support frame 6, the air path valve 212 is operated to control the cylinder shaft 131 to extend downward, and the upper ejector plate mounting frame 4 and the upper ejector plate component 3 are synchronously driven to be pressed down along the optical axis 12. When the lower end surface of the cylinder connecting piece 42 on the upper ejector mounting frame 4 contacts the upper end surface of the battery height limiting hexagonal studs 62 on both sides of the floating support frame, and the upper ejector contacts the upper end surface of the battery 55, the downward pressure of the cylinder is transmitted to the floating support frame 6, driving the floating support frame 6 and the tray body 5 as a whole to move forward It moves downward until the bottom of the floating support frame 6 contacts the upper end face of the floating lower limit hexagonal stud 15, at which time the lower ejector spring forms elastic contact with the lower end face of the battery 55, and the bottom surface of the tray body 5 contacts the sheet metal surrounding edge of the lower ejector disk component 7, forming an air duct that is connected from top to bottom and closed on all sides; at this time, cold air is ejected from the horizontal air duct outlet 2101, enters the lower ejector disk component 7 from the lower ejector disk air inlet 731, and then enters the tray from the tray air vent 53 at the bottom of the tray. After flowing through the battery 55, it diffuses from the surrounding areas and the upper ejector disk air vent 321 of the upper ejector disk component 3 to dissipate heat to the battery 55.

[0028] The tray body 5 is slidably mounted on the floating support frame by the guiding action of the guide strip 63 on the floating support frame 6. The tray body 5 is used to stack the batteries 55. A lower ejector hole 52 is provided at the bottom of the tray body 5 to expose the lower end surface of the battery.

The cylinders 13 on the left and right sides are controlled by the same air circuit valve 212 through parallel pipe connection, thereby ensuring stable lifting and falling of the upper ejector disk component 3. Example

[0032] like Figure 20 to Figure 23 As shown, this embodiment provides a needle bed type lithium battery capacity splitting device with a heat dissipation device, including the above-mentioned needle bed type lithium battery capacity splitting heat dissipation device, and also includes a frame module, the frame module is divided into a front end and a rear end isolated from each other, the front end is installed with the needle bed module 100, and the two sides of the rear end are installed with a capacity splitting power supply board 201 for powering the upper ejector body 31 and the lower ejector body 76; the installation position of the needle bed module 100 is a semi-enclosed structure, and the front side of the frame module is provided with an openable and closable movable compartment door 210, a module side door 211, and an air circuit valve 212, and the top is provided with a cold air inlet 213 and a cold air exhaust 214. ; The cold air inlet 213 is connected to the air inlet 213 arranged on the top of the total horizontal air inlet duct 23; the installation area of ​​the chemical component power board 201 is a semi-closed structure and normal temperature vents 224 are opened at the lower ends of both sides of the installation area, and the rear end of the rack module is provided with an openable power side cabinet door 220 and a power rear cabinet door 221, and a normal temperature air inlet 222 and a normal temperature exhaust port 223 are provided on the top. An air duct is formed inside the power cabinet. Normal temperature air enters from the normal temperature air inlet 222 and flows through the surface of the power board, taking away heat, and finally discharged from the normal temperature exhaust port 223.

[0033] The cold air inlet 213 is installed with a cold air active fan 2131, and the normal temperature air inlet 222 is installed with a normal temperature active fan 2221, both of which are used to ensure and enhance the air intake power.

[0034] The cold air active fan 2131 is connected to the cold air inlet soft air duct 2132, and two cold air exhaust outlets 214 are provided and respectively connected to the cold air exhaust soft air ducts 2141; the normal temperature active fan 2221 is connected to the normal temperature air inlet soft air duct 2222; two normal temperature exhaust outlets 223 are provided and respectively connected to the normal temperature exhaust soft air ducts 2231.

The design of vertical and horizontal air ducts forms an effective air duct system, which helps to evenly distribute the cold air in each storage location. Example

[0036] like Fig.24 , Fig.25As shown, this embodiment provides a needle bed type lithium battery capacity dissipation system, including a workshop 400 and an air conditioning room 407, wherein a plurality of needle bed type lithium battery capacity dissipation devices are installed in the workshop 400, and a cold air supply main pipe 401 and a cold air recovery main pipe 402 connected to the air conditioning room are arranged in the workshop 400, and the cold air inlet main pipes 401 of the plurality of needle bed type lithium battery capacity dissipation devices in the workshop are connected to the cold air supply main pipe 401 through the cold air inlet soft air pipe 2132, and the cold air exhaust port 2133 is connected to the cold air exhaust port 2134. 14 is connected to the cold air recovery main pipe 402 through the cold air exhaust soft air duct 2141, and the workshop is also equipped with an outdoor air supply main pipe 403 and an outdoor exhaust main pipe 404 connected to the outside, and the normal temperature air inlet soft air duct 2222 and the normal temperature exhaust soft air duct 2231 of the needle bed type lithium battery component capacity heat dissipation equipment are respectively connected to the outdoor air supply main pipe 403 and the outdoor exhaust main pipe 404, a blower 405 is installed at the inlet of the outdoor air supply main pipe 403, and an exhaust fan 406 is installed at the outlet of the outdoor exhaust main pipe 404.

[0037] The workshop is rationally arranged according to the plan and connected by a unified piping system to form a needle-bed type lithium battery chemical composition production line with intelligent temperature control.

[0038] When the above technical solution is adopted, multiple needle bed type lithium battery chemical component cooling equipment are reasonably arranged in the workshop according to the plan and connected by a unified pipeline system to form a needle bed type lithium battery chemical component production line with intelligent temperature control. During operation, the cold air is distributed to each cabinet through the hose from the main pipe, and then distributed to each storage position through the internal air duct, so that the cold air source and temperature of all needle bed cabinet storage positions under the same air supply system configuration are consistent, so that the temperature difference of each machine and each storage position is very small, ensuring that the industry requirements are met. The cold air after passing through the battery is discharged through the exhaust port and then collected through the main air duct before returning to the air-conditioned room. Since the temperature of the cold air after passing through the battery will rise within 4 degrees, when the temperature difference between the cold air at the cabinet inlet and the outdoor is greater than the temperature difference with the cabinet outlet, the cold air is concentrated and returned to the air-conditioned room for reuse, which can further reduce the cooling energy consumption.

[0039] Since the hot air from the power cabinet is also connected through a hose and connected to the external ventilation system through the main pipeline, the hot air from the power cabinet is isolated from the workshop and will not affect the ambient temperature of the workshop, thereby keeping the temperature of the workshop at normal temperature and improving the comfort of the workshop production environment.

The description of the specification is only for the sake of clarity and is not intended to limit the scope of protection of the present invention. The specification should be taken as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art and are within the scope of protection of the present invention.
