[0045] The principle and structure of the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0046] Embodiment 1

[0047] To reduce the occupied space of the liquid cooling unit 20 and prevent the leakage of the liquid cooling unit 20 from affecting the operation of the energy storage system 40 in the energy storage cabinet, the liquid cooling unit 20 is assembled on the cabinet door 10 of the energy storage cabinet. And for the convenience of disassembling or assembling the liquid cooling unit 20 from the cabinet door 10, referring to the attached Figure 1-2 , the present utility model provides an integrated door-type liquid cooling unit, including: a plurality of support frames 101 for supporting the liquid cooling unit 20 are provided on the cabinet door 10 along its X-axis direction, and a first locking portion 102 is provided on one side of each support frame 101 along the Y-axis direction and away from the cabinet door 10. A first buckle portion 201 is provided on the bottom of the liquid cooling unit 20 along the X-axis direction and corresponding to each first locking portion 102.

[0048] The first locking portion 102 can be engaged with the corresponding first buckle portion 201 in a matching manner.

[0049] In this way, the liquid cooling unit 20 is first placed on the support frame 101, and then the first locking portion 102 on the support frame 101 is engaged with the corresponding first buckle portion 201 of the liquid cooling unit 20, so that the liquid cooling unit 20 is assembled on the cabinet door 10, reducing the space occupied by the liquid cooling unit 20 in the cabinet body 30 of the energy storage cabinet, improving the space utilization rate of the energy storage cabinet, and separating the liquid cooling unit 20 from the energy storage system 40 (the energy storage system 40 includes energy storage batteries, power converters, etc.) located in the cabinet body 30. In this way, even if the liquid cooling unit 20 leaks, it will not affect the normal operation of the energy storage system 40, and also reduce the probability of occurrence of short circuits, fires and other situations, improving the safety of the energy storage cabinet.

[0050] Moreover, the liquid cooling unit 20 is detachably connected to the cabinet door 10 through the first locking portion 102 and the first buckling portion 201. In this way, when the liquid cooling unit 20 needs to be repaired, it is not necessary to disassemble the entire energy storage cabinet. It is only necessary to disengage the first locking portion 102 from the first buckling portion 201, and then remove the liquid cooling unit 20 from the cabinet door 10 and repair the liquid cooling unit 20 separately, so as to reduce the repair time, improve the repair efficiency, and reduce the repair cost.

[0051] Moreover, the detachable connection between the liquid cooling unit 20 and the cabinet door 10 can also simplify the transportation process, reduce the transportation cost, and be more flexible during installation, reducing the complexity of on-site construction.

[0052] It should be noted that preferably four support frames 101 are provided in this embodiment. The four support frames 101 are equidistantly arranged along the X-axis direction of the cabinet door 10, and a first locking portion 102 is provided on each side of each support frame 101 along the Y-axis direction and away from the cabinet door 10.

[0053] It should be noted that the top and bottom of the liquid cooling unit 20 in this embodiment are in the Z-axis direction; and devices such as condensers and fans provided in the liquid cooling unit 20 are all prior arts and will not be elaborated here.

[0054] To further ensure the stability of the liquid cooling unit 20 assembled on the cabinet door 10, refer to the attached Figure 1 and 3 , a plurality of second locking portions 202 are also equidistantly provided along the X-axis direction on the side of the top of the liquid cooling unit 20 close to the cabinet door 10, and a second buckling portion 103 is also provided on the cabinet door 10 along the X-axis direction corresponding to the second locking portions 202.

[0055] The second locking portion 202 can be engaged and locked with the corresponding second buckling portion 103.

[0056] In this way, through the matching engagement of all the first locking portions 102 and the corresponding first buckling portions 201, the positions of the liquid cooling unit 20 in the X-axis direction and the Z-axis direction of the cabinet door 10 are limited to prevent the liquid cooling unit 20 from moving or shaking along the X-axis direction and the Z-axis direction; and then through the matching engagement of all the second locking portions 202 and the corresponding second buckling portions 103, the position of the liquid cooling unit 20 in the Y-axis direction of the cabinet door 10 is limited to prevent the liquid cooling unit 20 from moving or shaking along the Y-axis direction.

[0057] It should be noted that preferably four second locking portions 202 are provided in this embodiment. In this way, the liquid cooling unit 20 is fixed on the cabinet door 10 through the four first locking portions 102 at the top and the four second locking portions 202 at the bottom, ensuring the stability of the liquid cooling unit 20 on the cabinet door 10.

[0058] Specifically, to ensure the stability of the connection between the liquid cooling unit 20 and the cabinet door 10, the present utility model proposes a structure of the first locking portion 102 and the second locking portion 202. Refer to the attached Figure 2-3 , both the first locking portion 102 and the second locking portion 202 include a base 1021, a handle 1022, and a buckle 1023.

[0059] On one side of each support frame 101 away from the cabinet door 10 and on one side of the top of the liquid cooling unit 20 close to the cabinet door 10, a plurality of bases 1021 are fixedly provided. Both sides of each base 1021 in the X-axis direction are rotatably connected to the handle 1022, and buckle rings 1023 are sleeved on both sides of the handle 1022 in the X-axis direction.

[0060] When the handle 1022 rotates relative to the base 1021, the handle 1022 drives the buckle ring 1023 to be engaged with the corresponding first buckle portion 201 or the second buckle portion 103 in a matching manner.

[0061] In this way, when the handle 1022 is closed relative to the base 1021, the handle 1022 covers the base 1021 in a matching manner; when the handle 1022 is opened relative to the base 1021 and the maximum opening angle is 90°, the buckle ring 1023 will disengage from the corresponding clamping groove 1031. At this time, the liquid cooling unit 20 will be disconnected from the cabinet door 10, and the disassembly work is completed.

[0062] Among them, a plurality of first screw holes 1024 are provided on the bases 1021 of both the first locking portion 102 and the second locking portion 202. In this way, each first screw hole 1024 of the first locking portion 102 passes through a bolt to fix the first locking portion 102 on the support frame 101, and each first screw hole 1024 of the second locking portion 202 passes through a bolt to fix the second locking portion 202 on the top of the liquid cooling unit 20; a plurality of second screw holes 1032 are provided on both the first buckle portion 201 and the second buckle portion 103. In this way, each second screw hole 1032 of the first buckle portion 201 passes through a bolt to fix the first buckle portion 201 on the bottom of the liquid cooling unit 20, and each second screw hole 1032 of the second buckle portion 103 passes through a bolt to fix the second buckle portion 103 on the cabinet door 10.

[0063] To prevent the buckle ring 1023 from disengaging from the first buckle portion 201 or the second buckle portion 103 due to the vibration generated during the operation of the energy storage cabinet and further strengthen the stability of the liquid cooling unit 20 assembled on the cabinet door 10, refer to the attached Figure 5 , the bottoms of both the first buckle portion 201 and the second buckle portion 103 are bent upward to form a clamping groove 1031, and the clamping groove 1031 can be engaged with the corresponding buckle ring 1023 in a matching manner.

[0064] It should be noted that the bottom and top of the first buckle part 201 and the second buckle part 103 in this embodiment refer to the Z-axis direction.

[0065] To receive the liquid leakage fault of the liquid cooling unit 20 in advance and prevent the liquid cooling unit 20 from continuing to work after leakage, which may affect the normal operation of the energy storage cabinet, refer to the appendix Figure 1 and 4 , a water receiving tray 104 is further provided at the bottom of the cabinet door 10 corresponding to the bottom of the liquid cooling unit 20, and a liquid level sensor 105 is provided at the bottom of the water receiving tray 104.

[0066] Among them, a control center (not shown in the full text, the same hereinafter) is also provided in the energy storage cabinet, and the control center is electrically connected to the liquid level sensor 105. When the liquid cooling unit 20 leaks and the liquid flows to the water receiving tray 104, the liquid level sensor 105 located at the bottom of the water receiving tray 104 will send a warning electrical signal to the control center. After receiving the signal, the control center will send a liquid leakage alarm to the display screen on the energy storage cabinet to remind the user that there is a liquid leakage in the liquid cooling unit 20 and it needs to be repaired in time. At the same time, the liquid cooling unit 20 will automatically stop to avoid large-area leakage, which can effectively prevent the liquid leakage of the liquid cooling unit 20 from damaging the energy storage system 40 in the energy storage cabinet and improve the safety and reliability of the liquid cooling unit 20.

[0067] It should be noted that, refer to the appendix Figure 4 and 6 , a drain pipe 1041 is also connected to the bottom of the water receiving tray 104, and the end of the drain pipe 1041 penetrates through the cabinet door 10 and is connected to the drain port 1042 on the cabinet door 10. In this way, the liquid leakage of the liquid cooling unit 20 will flow to the external storage device (not shown in the full text, the same hereinafter) through the drain pipe 1041, preventing the liquid leakage of the liquid cooling unit 20 from accumulating in the water receiving tray 104 and affecting the normal operation of the energy storage cabinet.

[0068] And in this embodiment, the drain port 1042 is preferably arranged at the lower part of the side of the cabinet door 10 facing away from the liquid cooling unit 20.

[0069] To facilitate the liquid cooling unit 20 on the cabinet door 10 to dissipate heat from the energy storage system 40 in the cabinet body 30, refer to the appendix Figure 6-7 , an air outlet 107 and an air return port 106 are successively arranged on the cabinet door 10 corresponding to the liquid cooling unit 20 along the X-axis direction.

[0070] Among them, the air return port 106 sucks air into the cabinet body 30, and the air outlet 107 blows air out of the cabinet body 30 to form an air circulation.

[0071] Among them, to protect the air return port 106 from rain, dust, wind and sand, etc., refer to the appendix Figure 7-8, the air return opening 106 is provided with a rotatable first grille shutter 108, and a first gear 1082 is provided at one end of each first grille 1081 in the first grille shutter 108 along the X-axis direction.

[0072] The cabinet door 10 is further provided with a first driving device 109 electrically connected to the control center. The first driving device 109 is located above the first grille shutter 108, and the output end of the first driving device 109 and all the first gears 1082 are on the same vertical line, and a first transmission member 1083 is provided around the output end of the first driving device 109 and all the first gears 1082.

[0073] In this way, when it is necessary to adjust the opening angles of all the first grilles 1081, the control center will control the first driving device 109, and then the first driving device 109 will drive all the first gears 1082 to rotate through the first transmission member 1083. The first gear 1082 will then drive the corresponding first grille 1081 to rotate, thereby adjusting the opening angles of all the first grilles 1081, and further preventing rain or dust from the outside from entering the cabinet body 30 through the air return opening 106 and affecting the operation of the energy storage system 40.

[0074] Among them, different opening angles of the first grille 1081 (equivalent to different angles between the first grille 1081 and the cabinet door 10) can play different degrees of protection roles. Specifically, the oncoming wind speed blowing towards the energy storage cabinet is detected by the wind speed and direction sensor 112 provided at the air return opening 106, and the opening angle of the first grille 1081 is appropriately adjusted. According to different installation environments, the oncoming wind speed blowing towards the energy storage cabinet can be set in three gears, namely a 1 gear, a 2 gear, and a 3 gear, and the set wind speeds are a 1 > a 2 > a 3 ; when the wind speed < a 3 , the opening angle of the first grille 1081 ≥ 60°; when a 2 > wind speed > a 3 , 60° > the opening angle of the first grille 1081 ≥ 45°; when a 1 > wind speed > a 2 , 45° > the opening angle of the first grille 1081 ≥ 30°; when the wind speed > a 1 , 30° > the opening angle of the first grille 1081 ≥ 15°. The smaller the opening angle of the first grille 1081, the better the protection effect.

[0075] Among them, in order to prevent rain, dust, wind and sand, etc. from the air outlet 107, refer to the attached Figure 7 and 9, the air outlet 107 is provided with a rotatable second grille shutter 110, and each second grille 1101 in the second grille shutter 110 is provided with a second gear 1102 at one end along the X-axis direction.

[0076] The cabinet door 10 is further provided with a second driving device 111 electrically connected to the control center. The second driving device 111 is located at the lower part of the second grille shutter 110, and the output end of the second driving device 111 and all the second gears 1102 are on the same vertical line, and a second transmission member 1103 is provided around the output end of the second driving device 111 and all the second gears 1102.

[0077] In this way, when it is necessary to adjust the opening angles of all the second grilles 1101, the control center will control the second driving device 111, and then the second driving device 111 will drive all the second gears 1102 to rotate through the second transmission member 1103. The second gears 1102 will then drive the corresponding second grilles 1101 to rotate, thereby adjusting the opening angles of all the second grilles 1101, and further preventing rain or dust from the outside from entering the cabinet body 30 through the air outlet 107 and affecting the operation of the energy storage system 40.

[0078] Among them, different opening angles of the second grille 1101 (equivalent to different angles between the second grille 1101 and the cabinet door 10) can play different degrees of protection roles. Specifically, according to the wind speed and direction sensor 112 provided at the air return opening 106, the oncoming wind speed blowing towards the energy storage cabinet is detected, and the opening angle of the second grille 1101 is appropriately adjusted. According to different installation environments, the oncoming wind speed blowing towards the energy storage cabinet can be set in three gears, namely a 1 gear, a 2 gear, and a 3 gear, and the set wind speeds are a 1 > a 2 > a 3 ; when the wind speed < a 3 , the opening angle of the second grille 1101 ≥ 60°; when a 2 > wind speed > a 3 , 60° > the opening angle of the second grille 1101 ≥ 45°; when a 1 > wind speed > a 2 , 45° > the opening angle of the second grille 1101 ≥ 30°; when the wind speed > a 1 , 30° > the opening angle of the second grille 1101 ≥ 15°. The smaller the opening angle of the second grille 1101, the better the protection effect.

[0079] It should be noted that the first driving device 109 and the second driving device 111 are both preferably motors, and the first transmission member 1083 and the second transmission member 1103 are both preferably transmission chains.

[0080] Moreover, in this embodiment, the opening angles of the first grille 1081 and the second grille 1101 are synchronized, that is, within the same time, the opening angles of the first grille 1081 and the second grille 1101 are the same.

[0081] Of course, in other embodiments (not shown in the figure), a dual-axis motor is provided at the upper part between the first grille shutter 108 and the second grille shutter 110. A first output shaft is provided on one side of the dual-axis motor facing the first grille shutter 108, and the first output shaft and all the first gears 1082 are on the same vertical line, and a first transmission member 1083 is provided around the first output shaft and all the first gears 1082; a second output shaft is provided on the other side of the dual-axis motor facing the second grille shutter 110, the second output shaft and all the second gears 1102 are on the same vertical line, and a second transmission member 1103 is provided around the second output shaft and all the second gears 1102. In this way, when the dual-axis motor is started, the first output shaft and the second output shaft can be rotated simultaneously, thereby synchronously adjusting the opening angles of the first grille 1081 and the second grille 1101, and further preventing rainwater or dust from the outside from entering the cabinet 30 and affecting the operation of the energy storage system 40.

[0082] Among them, to facilitate adjusting the fan speed in the liquid cooling unit 20 according to the wind speed and direction of the external environment, so as to reasonably utilize the environmental wind to reduce the energy consumption of the liquid cooling unit 20 and improve the energy efficiency ratio of the liquid cooling unit 20, referring to the attached Figure 6 a wind speed and direction sensor 112 is further provided at the air return opening 106 or the air outlet 107 for detecting the wind speed and direction of the external environment.

[0083] Among them, in this embodiment, it is illustrated by taking the wind speed and direction sensor 112 being provided at the air return opening 106, and the wind speed and direction sensor 112 can also be replaced by an ultrasonic wind speed and direction meter or other instruments or devices capable of detecting wind speed and direction.

[0084] Specifically, the wind speed and direction sensor 112 detects the wind speed and direction of the external environment in real time and uploads the detection information to the control center. In this way, when the wind direction of the external environment is consistent with the wind direction of the air return opening 106 of the liquid cooling unit 20, then through the known formula:

[0085] Q = cmΔt;

[0086] where Q is the heat exchange amount of the liquid cooling unit 20, c is the specific heat capacity of air, m is the mass flow rate of air, and Δt is the temperature difference between the inlet and outlet of the condenser in the liquid cooling unit 20.

[0087] To keep the heat exchange capacity Q of the liquid cooling unit 20 unchanged, given that the specific heat capacity c of air is a constant value, the temperature difference Δt between the inlet and outlet of the condenser is generally between 5 and 15 °C. Thus, it can be satisfied by adjusting the mass flow rate m of air, and m = m 风机 +m 环 (m 风机 is the mass flow rate of the fan of the liquid cooling unit 20. When the rotational speed of the fan is high, the mass flow rate of the fan will increase, and when the rotational speed of the fan is low, the mass flow rate of the fan will decrease; m 环 is the mass flow rate of the external environment).

[0088] Therefore, when m 环 increases, m 风机 can be correspondingly reduced to keep the total mass flow rate of air passing through the liquid cooling unit 20 unchanged. And the decrease of m 风机 means that the rotational speed of the fan of the liquid cooling unit 20 will also be correspondingly reduced. With other states of the liquid cooling unit 20 remaining unchanged, the reduction of the fan rotational speed will also correspondingly reduce the total power consumed by the liquid cooling unit 20. In this way, the liquid cooling unit 20 can dynamically adjust the fan rotational speed according to the external wind speed and direction, reasonably utilize the external wind to reduce the energy consumption of the liquid cooling unit 20, and improve the energy efficiency ratio of the liquid cooling unit 20.
