Fig. 2 is a schematic structural diagram illustrating a view angle of the battery replacing cabinet 001 in an embodiment of the present application after removing the first side plate 103, in which the battery cavity 315 is indicated by a broken line to facilitate a partial cross-section of the battery cavity 315, and the battery compartment 300 is not indicated to form an actual opening in the broken line. Fig. 3 shows a schematic structural diagram of another view angle of the battery swapping cabinet 001 in an embodiment of the present application after the first side plate 103 is removed. Fig. 4 shows a partially enlarged view of the area a in fig. 3.

Referring to fig. 1, the battery replacement cabinet 001 includes a cabinet body 100, and the cabinet body 100 is substantially rectangular. The electricity changing cabinet 001 includes a first top panel 101, a second top panel 102, a first side panel 103, a second side panel 104, a third side panel 105, and a fourth side panel 106. The first top plate 101 and the second top plate 102 are arranged at intervals along a first direction X, when the battery replacing cabinet 001 is used, the battery replacing cabinet 001 is placed on a horizontal plane, the first direction X is approximately parallel to a vertical direction, and the first top plate 101 is located below the second top plate 102. The first side panel 103, the second side panel 104, the third side panel 105 and the fourth side panel 106 are located between the first top panel 101 and the second top panel 102. The first side plate 103 and the second side plate 104 are disposed at intervals along the second direction Y, and the third side plate 105 and the fourth side plate 106 are disposed at intervals along the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. Referring to fig. 1 and fig. 2, the first top plate 101, the second top plate 102, the first side plate 103, the second side plate 104, the third side plate 105 and the fourth side plate 106 enclose to form an accommodating cavity 110.

Referring to fig. 2, 3 and 4, the power exchange cabinet 001 further includes an isolation portion 200, and the isolation portion 200 is fixedly connected to the cabinet 100. The partition 200 includes a main body portion 230, a first extension portion 210, and a second extension portion 250. The main body portion 230 extends in the first direction X, and the first extension portion 210, the main body portion 230, and the second extension portion 250 are sequentially connected such that the partition 200 is substantially zigzag-shaped. The accommodating chamber 110 is divided into a first sub-chamber 111 and a second sub-chamber 113 by the partition 200, the first sub-chamber 111 is close to the third side plate 105, and the second sub-chamber 113 is close to the fourth side plate 106. The body part 230 is provided with a plurality of first mounting holes through which the first and

second sub-chambers

111 and 113 communicate.

A first opening 130 is provided in the first top plate 101, the first opening 130 communicates with the first sub-chamber 111, and an airflow outside the cabinet 100 can enter the first sub-chamber 111 through the first opening 130. The accommodating chamber 110 forms an interior of the cabinet 100, and an exterior of the cabinet 100 is located at an exterior of the cabinet 100 and corresponds to the accommodating chamber 110. A second opening 150 is provided in the third side panel 105, the second opening 150 is provided near the second top panel 102, the second opening 150 is communicated with the second sub-chamber 113, and the second opening 150 enables the airflow of the second sub-chamber 113 to circulate to the outside of the cabinet 100. When the first mounting holes communicate the first sub-chamber 111 and the second sub-chamber 113, air outside the cabinet 100 enters the first sub-chamber 111 through the first opening 130, air in the first sub-chamber 111 enters the second sub-chamber 113 through each first mounting hole, and air in the second sub-chamber 113 circulates to the outside of the cabinet 100 through the second opening 150.

The power changing cabinet 001 further includes battery compartments 300 corresponding to the first mounting holes one to one. The battery compartment 300 and the main body 230 are connected to the first mounting hole, the portion of the battery compartment 300 located in the first sub-cavity 111 forms a first portion 330, and the portion of the battery compartment 300 located in the second sub-cavity 113 forms a second portion 350. A battery cavity 315 is formed in the battery compartment 300 extending from the first portion 330 to the second portion 350, and a battery may be received in the battery cavity 315. The first portion 330 is provided with a first through hole portion 311 communicating the first sub-chamber 111 and the battery chamber 315, the second portion 350 is provided with a second through hole portion 313 communicating the second sub-chamber 113 and the battery chamber 315, the first through hole portion 311, the battery chamber 315 and the second through hole portion 313 form a circulation channel 310, after the battery compartment 300 is installed in the first installation hole, the first sub-chamber 111 and the second sub-chamber 113 are communicated through the circulation channel 310, so that gas outside the cabinet 100 enters the first sub-chamber 111 through the first opening 130, gas in the first sub-chamber 111 enters the second sub-chamber 113 through each circulation channel 310, and gas in the second sub-chamber 113 flows to the outside of the cabinet 100 through the second opening 150.

When the first opening 130 and the second opening 150 circulate gas, the gas entering the first sub-chamber 111 enters the second sub-chamber 113 through each battery compartment 300, and then is discharged out of the power exchange cabinet 001 through the second sub-chamber 113, so that the circulation channels 310 formed by each battery compartment 300 are in parallel connection, and the gas entering the accommodating chamber 110 does not need to sequentially circulate through each battery compartment 300 and then flow out of the accommodating chamber 110. The battery compartments 300 are connected in parallel, so that the cooling effect of each battery compartment 300 is substantially the same, and it is difficult to generate heat accumulation in each battery compartment 300, so that the heat dissipation effect of the battery compartments 300 is better.

It can be understood that, when the first opening 130 is located below the second opening 150, the air outside the switch cabinet 001 may also be introduced through the second opening 150, and the air flows out of the first opening 130 after flowing through the accommodating chamber 110.

The power conversion cabinet 001 further includes a first airflow driving member 410, the first airflow driving member 410 and the cabinet body 100 are fixed at the second opening 150, and when the first airflow driving member 410 works, the first airflow driving member 410 drives the air in the second sub-cavity 113 to flow out of the cabinet body 100. When the first airflow driving member 410 drives the air in the second sub-chamber 113 to flow out of the cabinet 100, a negative pressure is formed in the second sub-chamber 113, so that the air in the first sub-chamber 111 enters the second sub-chamber 113 through the flow channel 310, and correspondingly, the first sub-chamber 111 also forms a negative pressure, so that the air out of the cabinet 100 enters the first sub-chamber 111 through the first opening 130. When batteries are placed in the battery cavity 315 and the batteries need to be cooled, low-temperature gas outside the cabinet 100 can flow through the paths of the first sub-cavity 111, the flow channel 310 and the second sub-cavity 113, and when the gas enters the battery cavity 315 in the flow channel 310, the gas cools the batteries in the battery cavity 315. When the first airflow driver 410 does not work, the first airflow driver 410 blocks the second opening 150, so that the accommodating cavity 110 is difficult to exchange air with the outside of the cabinet 100.

Optionally, the first airflow driving member 410 is a ventilator, and the ventilator drives the blades to rotate by electric power, and the rotation of the blades drives the air in the second sub-chamber 113 to flow out of the cabinet 100.

It is understood that the first air flow driver 410 may also be fixed to the cabinet 100 at the first opening 130, and the first air flow driver 410 drives the air outside the cabinet 100 to flow into the first sub-chamber 111 through the first opening 130. When the first airflow driving member 410 drives the air outside the cabinet 100 to flow into the first sub-chamber 111, a high pressure is formed in the first sub-chamber 111, so that the air in the first sub-chamber 111 enters the second sub-chamber 113 through the flow passage 310, and correspondingly, the second sub-chamber 113 also forms a high pressure, so that the air in the second sub-chamber 113 flows out of the cabinet 100.

The first opening 130 is disposed on the first top board 101, and when the power transforming cabinet 001 is disposed on a horizontal plane, the first top board 101 faces the horizontal plane, so that the distance between the first top board 101 and the horizontal plane is small, and the first top board 101 and the first opening 130 disposed on the first top board 101 are hidden. On one hand, the first opening 130 can be protected, the probability that the first opening 130 is damaged by people is reduced, on the other hand, relatively large sundries can be isolated, and the first opening 130 is prevented from being blocked by the large sundries. Moreover, when the first opening 130 is not ventilated, part of the sundries at the first opening 130 can fall down through self gravity, and the risk that the first opening 130 is blocked by the sundries is reduced.

A filter screen is further disposed at the first opening 130, so that the gas entering the accommodating chamber 110 through the first opening 130 has less impurities, thereby maintaining the cleanness inside the accommodating chamber 110.

The first opening 130 is provided in the first top plate 101, and the first extending portion 210 of the partition 200 avoids the first top plate 101, so that the first opening 130 can occupy a large area on the first top plate 101 as much as possible. The first extending portion 210 extends substantially parallel to the third direction Z from an end of the main body portion 230 near the first top board 101, as viewed in a cross section perpendicular to the second direction Y. An end of the first extension portion 210 away from the main body portion 230 is connected to the fourth side plate 106, and the first sub-cavity 111 is partially located between the first extension portion 210 and the first top plate 101. The gas introduced into the first sub-chamber 111 from the first opening 130 first enters between the first extension portion 210 and the first top plate 101, and then gradually enters the second sub-chamber 113 through each of the battery compartments 300.

A second extension is disposed at an end of the first airflow driver 410 away from the second top plate 102, and the second extension extends from an end of the main body portion 230 close to the second top plate 102 in parallel to the third direction Z. The first airflow driving member 410 and the second opening 150 are disposed between the second top plate 102 and the second extension portion, and disposed on the third side plate 105 through the second opening 150, so that the vertically falling dust and raindrops are difficult to directly enter the accommodating chamber 110 through the second opening 150, and the cleanness of the accommodating chamber 110 is maintained. The space between the second top plate 102 and the second extension may be used for mounting electronic components of the switch cabinet 001.

The first extension 210 further includes a first section 211, a second section 213, and a third section 215. The first segment 211 extends from an end of the main body part 230 close to the first top plate 101 along the third direction Z, the second segment 213 extends from an end of the first segment 211 far from the main body part 230 along the first direction X toward the first top plate 101, and the third segment 215 extends from an end of the second segment 213 far from the first end along the third direction Z to the fourth side plate 106. A second mounting hole is provided in the second section 213, and the first sub-chamber 111 and the second sub-chamber 113 can also communicate through the second mounting hole.

The switch cabinet 001 further comprises a heating element (not shown) and a second airflow driver 430. The second airflow driving member 430 and the isolation portion 200 are fixed at the second mounting hole. When the second airflow driving member 430 does not operate, the second airflow driving member 430 blocks the second mounting hole, so that it is difficult to exchange gas between the first sub-chamber 111 and the second sub-chamber 113 through the second mounting hole. When the second airflow driving member 430 is operated, the second airflow driving member 430 can drive the air in the second sub-chamber 113 to flow into the first sub-chamber 111. The heating element is disposed in the receiving cavity 110, and when the battery is placed in the battery cavity 315 and the battery needs to be heated, the operation of the first airflow driver 410 can be stopped and only the second airflow driver 430 can be operated. The gas in the accommodating cavity 110 is heated by the heating element and circulates through the circulation paths of the first sub-cavity 111, the circulation channel 310, the second sub-cavity 113, the second airflow driving element 430 and the first sub-cavity 111, and when the gas enters the battery cavity 315 in the circulation channel 310, the gas heats the battery in the battery cavity 315.

It is understood that the heating element may be disposed at any position of the first sub-chamber 111 or the second sub-chamber 113, and when the first airflow driving element 410 is not operated and the second airflow driving element 430 is activated, the gas in the accommodating chamber 110 circulates between the first sub-chamber 111 and the second sub-chamber 113. Through the multiple circulation of gas between the first sub-cavity 111 and the second sub-cavity 113, the heat generated by the heating element arranged at any position of the first sub-cavity 111 or the second sub-cavity 113 can be diffused into the whole accommodating cavity 110, so that the battery in the battery compartment 300 can be effectively heated.

Optionally, the second airflow driving member 430 is a server cooling fan, and the server cooling fan drives the blades to rotate through electric power, and the rotation of the blades drives the air in the second sub-chamber 113 to flow toward the first sub-chamber 111.

Optionally, the second airflow driver 430 has an air outlet end extending into the first sub-cavity 111, and the heating element and the second airflow driver 430 are fixed at the air outlet end. After the heating member produces the heat, this heat is taken away by the gas of the end of giving vent to anger fast, and what correspond with it, the gas that gets into first minute cavity 111 heats fast for the gas temperature in first minute cavity 111 is more even.

Fig. 5 shows a system diagram of a swapping cabinet 001 according to an embodiment of the present application.

Referring to fig. 5, the battery replacement cabinet 001 further includes a control portion 510 and a temperature sensor 530. The temperature sensor 530 is disposed in the battery cavity 315, and the temperature sensor 530 is electrically connected to the control unit 510. The first air flow driver 410, the second air flow driver 430 and the heating element 450 are also electrically connected to the control portion 510.

The temperature sensor 530 senses the temperature in the battery chamber 315, and the control unit 510 receives data from the temperature sensor 530 and determines the control. The control unit 510 stores a control program, in which a first temperature and a second temperature are preset, the first temperature calibrates the temperature in the battery cavity 315 to be lower than the working temperature threshold of the battery, and the second temperature calibrates the temperature in the battery cavity 315 to be higher than the working temperature threshold of the battery.

When the temperature sensed by the temperature sensor 530 reaches the first temperature, the control part 510 controls the second air current driving member 430 and the heating member 450 to operate, and the first air current driving member 410 stops operating. Since the first airflow driver 410 stops working, it is difficult to form the second sub-chamber 113 at the second opening 150 for exchanging air with the outside of the cabinet 100. The gas in the accommodating chamber 110 is driven by the second gas flow driving member 430 to circulate through the second sub-chamber 113, the second gas flow driving member 430, the first sub-chamber 111, the respective flow channels 310 (battery chambers 315), and the second sub-chamber 113. The heating member 450 heats the temperature in the accommodating chamber 110, circulates the heated gas into the battery chamber 315, and heats the battery in the battery chamber 315. Each of the flow channels 310 functions to communicate the first sub-chamber 111 and the second sub-chamber 113, and the gas in the first sub-chamber 111 can pass through each of the flow channels 310, that is, each of the cell chambers 315, substantially uniformly. Therefore, the batteries in each battery cavity 315 can be effectively heated, and the phenomenon that the temperature of part of the battery cavities 315 is obviously higher than that of the other part of the battery cavities 315 can be reduced.

When the temperature sensed by the temperature sensor 530 reaches the second temperature, the control part 510 controls the first air current driving part 410 to operate, and the second air current driving part 430 and the heating part 450 to stop operating. Since the second airflow driving member 430 stops operating, the gas exchange between the first sub-chamber 111 and the second sub-chamber 113 is difficult to be performed through the second mounting hole, so that the gas exchange in the first sub-chamber 111 and the second sub-chamber 113 is substantially performed through each of the flow passages 310. The air in the second sub-chamber 113 is driven to circulate to the outside of the cabinet 100 by the first airflow driving member 410, the second sub-chamber 113 forms a negative pressure and absorbs the air in the first sub-chamber 111 through the circulation channel 310, and the first sub-chamber 111 forms a negative pressure and absorbs the air outside the cabinet 100 through the first opening 130. The low-temperature gas outside the cabinet 100 circulates through the route of the first opening 130-the first sub-chamber 111-each circulation channel 310 (battery chamber 315) -the second sub-chamber 113-the second opening 150. The gas with lower external temperature is introduced through the first opening 130, and the gas cools the battery when passing through the accommodating chamber 110, and then the gas enters the second sub-chamber 113 and is discharged outside through the second opening 150.

The first extension portion 210 is fixedly connected to the horizontal frame 231 adjacent to the first top plate 101, and the second extension portion is fixedly connected to the horizontal frame 231 adjacent to the second top plate 102.

Fig. 7 is a schematic diagram illustrating a view angle of a battery compartment 300 according to an embodiment of the present disclosure. Fig. 8 is a schematic diagram of another view of the battery compartment 300 according to an embodiment of the present disclosure.

Referring to fig. 7 and 8, the battery compartment 300 includes a first sidewall 331, a second sidewall 333, and a third sidewall 335. The first sidewall 331 faces the first opening 130, i.e., the first sidewall 331 is a sidewall below the first portion 330. The second side wall 333 and the second side wall 333 are disposed on both sides of the first side wall 331 along the second direction Y. The first through hole 311 includes a first tuyere 3111 and a second tuyere 3113, the first tuyere 3111 is disposed at the second sidewall 333, and the second tuyere 3113 is disposed at the third sidewall 335. The gas in the accommodating chamber 110 is substantially in a flow direction from bottom to top, and the gas in the battery chamber 315 also has a tendency to move from bottom to top. When the gas entering the first sub-chamber 111 through the first opening 130 flows through the first portion 330 of the battery compartment 300, the gas flowing path in the first direction X is blocked by the first sidewall 331, so that the flow rate of the gas is reduced, the gas with reduced flow rate and changed direction enters the battery chamber 315 through the first tuyere 3111 and the second tuyere 3113, the gas can flow through various positions in the battery chamber 315 as much as possible in the battery chamber 315, and then flows out of the battery chamber 315 through the second through hole portion 313. The gas flowing out of the cell cavity 315 does not need to cool the other cell cavities 315 any more, and the second through hole part 313 is provided on the side wall of the second portion 350 near the second top plate 102, thereby facilitating the gas to approach the second opening 150 and to be discharged out of the second sub-cavity 113.

The fourth side plate 106 is provided with a third mounting hole corresponding to the battery compartment 300. One end of the battery compartment 300 close to the fourth side plate 106 is provided with a pick-and-place opening 301, and the pick-and-place opening 301 is arranged towards the third mounting hole. The battery cavity 315 is exposed through the access opening 301 and the third mounting hole, and an operator can take out the battery in the battery cavity 315 through the third mounting hole and the access opening 301, or put the battery in the battery cavity 315 through the third mounting hole and the access opening 301. The power changing cabinet 001 further comprises a bin door 610, wherein the bin door 610 is hinged with the fourth side plate 106 and is provided with a locking mechanism. After the locking mechanism is locked, the rotation of the bin door 610 and the fourth side plate 106 can be prevented, so that the bin door 610 closes the third mounting hole and the access opening 301, and an operator cannot take out the battery in the battery cavity 315 through the third mounting hole and the access opening 301. After the locking mechanism is unlocked, the compartment door 610 and the fourth side plate 106 can rotate relatively, the compartment door 610 is rotated to open the third mounting hole and the access opening 301, and an operator can take out the battery in the battery cavity 315 through the third mounting hole and the access opening 301.

Through the power conversion cabinet 001 provided by the application, the first sub-cavity 111 and the second sub-cavity 113 can be communicated through the flow channels 310, so that the battery cavities 315 are in a parallel relation. When gas is communicated between the first chamber 111 and the second chamber 113 to adjust the temperature in the cell chambers 315, the gas exchange between the first chamber 111 and the second chamber 113 passes through the cell chambers 315 in parallel, so that the temperature adjustment effect of the cell chambers 315 is substantially the same.
