[0028] The following is for reference. Figures 1 to 3 This invention describes a battery formation apparatus and formation system according to embodiments of the present invention.
[0029] The battery formation equipment of the first aspect of this utility model includes a formation cabinet 100 and a liquid cooling device.
[0030] The formation cabinet 100 is in the shape of a rectangular box. The formation cabinet 100 is provided with multiple formation units. The multiple formation units are arranged in a rectangular array on the front side wall of the formation cabinet 100. Each formation unit includes a formation circuit module 220. The formation circuit module 220 has a discharge resistor and two first contacts for connecting to the battery. The formation circuit module 220 is a conventional technical means in the art, and its specific structure will not be described in detail here.
[0031] The liquid cooling device includes a liquid cooling pipeline 300, which is provided with multiple liquid cooling blocks 321. Each liquid cooling block 321 is attached to a corresponding discharge resistor. Both ends of the liquid cooling pipeline 300 are connected to a cooling device to cool the coolant flowing through the liquid cooling pipeline 300. The coolant can be water or other suitable coolant. The liquid cooling blocks 321 can be copper blocks. The liquid cooling blocks 321 are attached to the discharge resistors so that the heat generated by the discharge resistors can be transferred to the liquid cooling blocks 321. Thermally conductive silicone grease or other thermally conductive media can be filled between the liquid cooling blocks 321 and the discharge resistors to improve heat transfer efficiency. A heat dissipation channel is provided inside the liquid cooling block 321. Both ends of the heat dissipation channel are connected to the liquid cooling pipeline 300, so that the coolant in the liquid cooling pipeline 300 can flow through the heat dissipation channel. The liquid cooling pipeline 300 is used to supply coolant flow to remove the heat from the liquid cooling block 321.
[0032] It is understandable that during the battery formation process, the battery's electrical energy is converted into heat energy in the discharge resistor when the battery discharges, and a large part of the heat generated by the formation unit comes from the discharge resistor.
[0033] This invention incorporates a liquid cooling device. During use, both ends of the heat dissipation channel are connected to the cooling device. The cooling device can remove the heat from the coolant in the heat dissipation channel, and the coolant can remove the heat from the discharge resistor. This prevents the heat dissipated by the discharge resistor from causing the temperature of the formation cabinet 100 to become too high, thus making the formation cabinet 100 less prone to failure due to high temperature.
[0034] In some embodiments of this utility model, the formation cabinet 100 includes a cabinet body 110 and a cabinet door 120. A power circuit module 400 is disposed inside the cabinet body 110, and formation units are disposed on the cabinet door 120. Each formation circuit module 220 is electrically connected to the power circuit module 400. The front sidewall of the formation cabinet 100 is the cabinet door 120, which is hinged to the cabinet body 110, allowing the cabinet door 120 to open and close. The formation cabinet 100 has an open state, in which the cabinet door 120 flips to the left side of the cabinet body 110, such as... Figure 2As shown; the cabinet door 120 can be a single door or a double door. The power circuit module 400 is a conventional technical means in this field, which only needs to supply power to the formation circuit module 220, and its specific structure will not be described in detail here. By setting the formation unit in the cabinet door 120 and the power circuit module 400 in the cabinet body 110, when the cabinet door 120 is opened, the formation unit moves away from the cabinet body 110 with the cabinet door 120, so that the formation unit and the power circuit module 400 can be separated, avoiding mutual obstruction and maintenance.
[0035] In some embodiments of this utility model, the formation unit further includes a placement seat 200 for placing the battery. The placement seat 200 is disposed on the side of the cabinet door 120 away from the cabinet body 110. The placement seat 200 is provided with two second contacts 210 for connecting to the battery. The formation circuit module 220 is disposed on the side of the cabinet door 120 facing the cabinet body 110. The two second contacts 210 are electrically connected to the two first contacts one-to-one. The formation circuit module 220 and the power circuit module 400 can be connected by flexible wires so that the formation circuit module 220 and the power circuit module 400 can maintain electrical connection when the cabinet door 120 is opened or closed; the placement seat 200 can be equipped with a clamping mechanism or other suitable mechanism to fix the battery; one of the first contacts is connected to one of the second contacts 210 by a wire, and the other first contact is connected to the other second contact 210 by a wire; under normal circumstances, the cabinet door 120 is in the closed state, which protects the formation circuit module 220 and the power circuit module 400 inside the formation cabinet 100. In use, the battery can be placed in the placement seat 200, and the two tabs of the battery are connected one-to-one to the two second contacts 210. Since the placement seat 200 is located on the side of the cabinet door 120 away from the cabinet body 110, that is, the placement seat 200 is located on the outer surface of the formation cabinet 100, such as Figure 1 As shown, this facilitates battery placement; when it is necessary to inspect or repair the battery formation equipment, opening the cabinet door 120 will simultaneously display the formation circuit module 220 and the power module, making operation convenient.
[0036] In some embodiments of this utility model, both ends of the liquid cooling pipe 300 are disposed on the cabinet body 110. The liquid cooling pipe 300 has a main body section 320 and two flexible hose sections 310. A liquid cooling block 321 is disposed on the main body section 320. The two flexible hose sections 310 are respectively connected between the two ends of the liquid cooling pipe 300 and the main body section 320. All liquid cooling blocks 321 are disposed on the main body section 320. One end of the liquid cooling pipe 300, one of the flexible hose sections, the main body section 320, the other flexible hose section 310, and the other end of the liquid cooling pipe 300 are connected in sequence. By providing two flexible hose sections 310, when the cabinet door 120 is opened or closed, causing the main body section 320 to move, both ends of the liquid cooling pipe 300 can remain in the original position, so that both ends of the liquid cooling pipe 300 can be disposed on the cabinet body 110, which facilitates the connection of both ends of the liquid cooling pipe 300 to the cooling device. When the cabinet door 120 is a double door, there can be two liquid cooling pipes 300, with each liquid cooling pipe 300 corresponding to one of the two door panels. The flexible hose section 310 can be made of flexible materials such as rubber or plastic.
[0037] In some embodiments of this utility model, the liquid cooling pipeline 300 is equipped with a delivery pump 330. The delivery pump 330 promotes the flow of coolant within the liquid cooling pipeline 300. The delivery pump 330 can be installed in the cabinet door 120, with a portion of the liquid cooling block 321 positioned between the delivery pump 330 and one end of the liquid cooling pipeline 300, and another portion of the liquid cooling block 321 positioned between the delivery pump 330 and the other end of the liquid cooling pipeline 300. Of course, in other embodiments of this utility model, the delivery pump 330 can be installed in the cabinet body 110.
[0038] In some embodiments of this utility model, all liquid cooling blocks 321 are connected in series; this ensures that the flow rate of coolant through all liquid cooling blocks 321 is consistent, avoiding the problem that the flow rate of coolant in a certain liquid cooling block 321 is too small, which could cause the corresponding discharge resistor to be damaged due to excessive temperature.
[0039] The formation system of the second aspect of this utility model includes a cooling device and at least one of the above-mentioned battery formation devices, such as... Figure 3 As shown, the cooling device includes a liquid storage tank 500 and an outdoor cooler 600. Both ends of the liquid cooling pipeline 300 and the outdoor cooler 600 are connected to the liquid storage tank 500. The outdoor cooler 600 is used to cool the coolant in the liquid storage tank 500 by allowing outdoor air to pass through. The outdoor cooler 600 can also be installed at a ventilation opening between the formation workshop and the outdoor environment, with a fan to direct the airflow from the ventilation opening to the outside; alternatively, the outdoor cooler 600 can be directly installed in the outdoor environment. In this way, the heat generated by the battery formation equipment can be dissipated to the outside through the liquid cooling device and the cooling device, reducing the heat dissipated from the battery formation equipment to the formation workshop and preventing the production work of the workers from being affected by excessively high ambient temperatures in the formation workshop.
[0040] In some embodiments of this utility model, there are multiple battery formation devices. It is understood that multiple battery formation devices are usually required in a formation workshop. In this embodiment, by connecting the liquid cooling pipes 300 of multiple battery formation devices to the same storage tank 500, the structure of the formation system is simplified and easier to set up. The storage tank 500 can be located indoors for easy maintenance or replenishment of coolant.
[0041] In some embodiments of this invention, the cooling device includes a heat pump chiller, which comprises a condenser and an evaporator disposed within a liquid storage tank 500. The condenser is an outdoor cooler 600. Heat pump chillers are conventional equipment in the art and can be purchased directly from the market; their specific structure will not be described in detail here. The heat pump chiller can transfer a large amount of heat from the liquid storage tank 500 to the outside, achieving the purpose of cooling the coolant within the liquid storage tank 500.
[0042] In some embodiments of this utility model, the outdoor cooler 600 is a water curtain heat exchanger or a finned heat exchanger. A circulation pipeline 610 is also provided between the outdoor cooler 600 and the liquid storage tank 500, and a circulation pump 611 is provided in the circulation pipeline 610, so that the coolant can circulate between the liquid storage tank 500 and the outdoor cooler 600. Compared with a heat pump chiller, this structure is simpler, has less power consumption, and lower operating costs.
[0043] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
