Furthermore, the term "and/or" (if present) as used in the specification, claims, or figures presented above refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

The embodiment of the application provides a composition, separation and capacitance integrated device, which comprises a shell 10, a power supply part 20 and a needle bed part 30, as shown in fig. 1 and fig. 2.

The inner cavity of the casing 10 is divided into an upper cabinet 110 and a lower cabinet 120 by the heat insulation plate 40, that is, the whole cabinet is divided into an upper sub-cabinet and a lower sub-cabinet by the heat insulation plate 40. It should be noted that, due to the arrangement of the heat insulation board 40, the power supply unit 20 and the battery cell respectively disposed in the upper and lower cabinets will not generate heat mutual influence. For example, the arrangement position of the heat insulation board 40 may be reasonably set according to the space required by the upper cabinet and the lower cabinet, for example, the arrangement of the heat insulation board 40 makes the upper cabinet 110 occupy one third of the inner cavity of the housing 10, and the lower cabinet 120 occupy two thirds of the inner cavity of the housing 10. For example, the housing 10 may be provided with a plurality of height steps, so that in practical use, the heat insulation plate 40 may be placed at the corresponding height step according to practical requirements. For example, the upper cabinet 110 and the lower cabinet 120 may be provided with their own doors independently, or may share one door.

The power supply unit 20 is disposed in the upper cabinet 110, and the power supply unit 20 refers to a plurality of power supply modules for supplying power to various power consuming parts in the device, such as an AC/DC power supply, a DC/DC power supply, a controller power supply, an inverter, and the like. In the present embodiment, at least one side panel of the upper cabinet 110 is provided with the air intake device 111, the top panel is provided with the air discharge device 112, and the air intake device 111 is disposed adjacent to the heat insulation panel 40. Illustratively, at least one of the four side panels of the upper cabinet 110 except for the heat insulation board 40 and the top panel is provided with the air intake device 111, for example, as shown in fig. 2, the side panel with the longest length (i.e., the rear side panel shown in the figure) is provided with the air intake device 111. Based on this, the air intake device 111 can supply the outside air to enter the upper cabinet body 110, the air exhaust device 112 is used for exhausting the air in the upper cabinet body 110 to the outside, because the air intake device 111 is arranged adjacent to the heat insulation board 40, the outside cold air can enter the upper cabinet body 110 through the air intake device 111 to cool the power supply unit 20, and simultaneously, the hot air generated after cooling is exhausted out of the upper cabinet body 110 through the air exhaust device 112, so that the cooling of the power supply unit 20 can be realized. In one embodiment, the air intake device 111 includes a plurality of air intake holes and/or at least one first fan for blowing outside air toward the upper cabinet 110, that is, outside cool air may enter the upper cabinet 110 through the air intake holes and the first fan to cool the power supply unit 20. Illustratively, the rear side plate of the upper cabinet 110 is provided with an air inlet, and the left and right side plates are both provided with a first fan. In one embodiment, the exhaust device 112 includes at least one second fan, and the second fan is used for blowing the air in the upper cabinet 110 to the outside, that is, the hot air in the upper cabinet 110 is "sucked" by the second fan. Illustratively, the top plate of the upper cabinet 110 is provided with a second fan array.

The needle bed component 30 is disposed on the lower cabinet 120, and the needle bed component 30 may include a bypass board, a current probe, a negative pressure suction nozzle, a cylinder, a temperature probe, and other components for forming a battery core into a component with a partial volume. In the embodiment of the present application, at least one cold air source 50 and a flow guiding device 60 are further disposed in the lower cabinet 120, and the flow guiding device 60 is configured to blow cold air blown from the at least one cold air source 50 toward the needle bed unit 30. Specifically, the cold air source 50 is a device having a capability of blowing out cold air, so that the cold air is blown to the needle bed component 30 by the flow guide device 60, that is, the temperature of the battery cell in the formation and partial volume can be reduced. For example, the source of the inlet air of the cold air source 50 may be air outside the lower cabinet 120, and the flow guiding device 60 may directly blow the cold air out of the lower cabinet 120 after blowing the cold air toward the electric cells. For example, the flow guiding device 60 may also blow the cold air to the cold air source 50 after blowing the cold air to the battery core, that is, the air inlet source of the cold air source 50 may be air after cooling the battery core, and the cold air source 50 has the capability of blowing out the cold air, so that the hot air may be changed into the cold air.

Therefore, in the embodiment of the present application, the power unit 20 and the needle bed unit 30 are integrated in one cabinet, so that the power unit and the needle bed unit can be connected by using a copper bar or the like, thereby avoiding the cost increase and the energy consumption increase caused by using a long cable. In the embodiment of the present invention, the power supply member 20 and the needle bed member 30 are separated from each other by the heat insulating plate 40, and the respective temperature lowering mechanisms are provided, so that the mutual influence of the two in terms of heat can be avoided.

In one embodiment, as shown in fig. 3 and 4, the cool air source 50 includes a water-cooled plate 510 and a third fan 520 fixedly connected thereto. The water cooling plate 510 has a plurality of air outlets 511, the air outlets 511 are disposed at the air outlet of the third fan 520, and the water cooling plate 510 further has a water inlet 512 and a water outlet 513. Therefore, the air blown by the third fan 520 passes through the air outlet holes 511, and the water flowing through the water-cooling plate 510 exists, so that the temperature of the air blown by the third fan 520 can be reduced by heat exchange, that is, the third fan 520 can blow out cool air. In addition, the flow rate of water in the water cooling plate 510 can be controlled by controlling the water inlet speed of the water inlet 512 and the water outlet speed of the water outlet 513, so that the temperature of air blown out by the third fan 520 is controlled. For example, during the use of the device, condensed water may be generated at the plurality of air outlet holes 511 due to heat exchange, and therefore, a water tank may be disposed below the plurality of air outlet holes 511, and the condensed water may be accumulated by the water tank. For example, the water tank may be provided with a water outlet, which may be connected with the water outlet 513 of the water cooling plate 510, that is, the condensed water is discharged through the water outlet 513, thereby saving the use of water pipes and other materials.

In one embodiment, as shown in fig. 5, the at least one cooling air source 50 is disposed adjacent to the heat insulation plate 40, that is, the air outlet channel of the cooling air source 50 is close to the heat insulation plate 40. Meanwhile, the heat insulation board 40 is provided with a gap (which can be understood as a relatively small air outlet hole) adjacent to the air outlet of the at least one cold air source 50. Therefore, since the gap is close to the cold air source 50, a small portion of the cold air blown by the cold air source 50 enters the upper cabinet body 110, and it can be understood that the small portion of the cold air dissipates heat to the power supply unit 20 and then is exhausted through the exhaust device 112, so that the heat dissipation capability of the upper cabinet body 110 is enhanced in the embodiment of the present application. In addition, because the air pressure at the air outlet of the cold air source 50 is relatively large, the air in the upper cabinet 110 does not flow into the lower cabinet 120, and the mutual influence between the power supply component 20 and the battery cell in terms of heat is avoided.

In an embodiment, as shown in fig. 6, the inner cavity of the lower cabinet body 120 is sequentially divided into a first air source area 1201, a needle bed placing area 1202 and a second air source area 1203 by the first vertical plate 121 and the second vertical plate 122, that is, the lower cabinet body 120 is divided into three areas by the two vertical plates, and similarly, the arrangement manner of the two vertical plates can be reasonably set.

In the present embodiment, the needle bed unit 30 includes a first needle bed 310 and a second needle bed 320 which are horizontally disposed. Illustratively, the first needle bed 310 and the second needle bed 320 are symmetrically disposed about a longitudinal axis of the needle bed placement area 1202, i.e., the first needle bed 310 and the second needle bed 320 are bilaterally symmetric. And, the area between the first needle bed 310 and the second needle bed 320 is used for placing the cell. Illustratively, the first and

second needle beds

310 and 320 may be used for component capacity of longer length cells, such as blade batteries. Based on this, in the present embodiment, the at least one cold air source 50 includes a first cold air source 510 and a second cold air source 520, and the first cold air source 510 and the second cold air source 520 are respectively disposed in the first air source region 1201 and the second air source region 1203. Illustratively, the first cold air source 510 is disposed in the first air source region 1201, and the second cold air source 520 is disposed in the second air source region 1203. Illustratively, by the diversion device 60, the cool air blown from the first cool air source 510 can be blown mainly to the first needle bed 310, and the cool air blown from the second cool air source 520 can be blown mainly to the second needle bed 320, thereby cooling the battery cell between the two needle beds. Illustratively, the cold air source is fixedly arranged on the vertical plate, and the vertical plate is provided with an opening or an air outlet hole adapted to the air outlet of the cold air source, so as to ensure that the cold air source can blow out cold air to the needle bed placing area 1202.

In an embodiment, as shown in fig. 6, the flow guiding device 60 includes at least one first top fan 610 and at least one second top fan 620, and the at least one first top fan 610 and the at least one second top fan 620 are both disposed above the battery cell and are respectively configured to blow air blown from the first cold air source 510 and air blown from the second cold air source 520 toward the battery cell. Illustratively, the cool air blown from the first cool air source 510 is mainly blown to the battery cells by the first top fan 610, and the cool air blown from the second cool air source 520 is mainly blown to the battery cells by the second top fan 620. For example, the set height of the cold air source may be equal to, slightly greater than or slightly less than the set height of the top fan, that is, the two are at almost the same height, so as to achieve a better flow guiding effect. Illustratively, the top fan may be fixedly connected with the needle bed unit 30.

In an embodiment, as shown in fig. 6, each of the first vertical plate 121 and the second vertical plate 122 is provided with a return device at the bottom, the return device is configured to blow air in the needle bed placing region 1202 to the first air source region 1201 or the second air source region 1203, that is, to a cold air source, and it is understood that an air inlet source of the cold air source is air after the electrical core is cooled. Illustratively, the bottom of the first vertical plate 121 is provided with an air return device 1211, and the bottom of the second vertical plate 122 is provided with an air return device 1221. Based on this, the deflector 60 further comprises at least one first bottom fan 630 and at least one second bottom fan 640. The at least one first bottom fan 630 is disposed below the first needle bed 310, and is configured to blow air blown by the at least one first top fan 610 toward the air return device 1211 of the first vertical plate 121, that is, cool air blown by the first cool air source 510 is blown toward the battery cell by the first top fan 610, then the air passing through the battery cell is blown toward the air return device 1211 by the first bottom fan 630, and finally the air return device 1211 blows air toward the first cool air source 510.
