[0036] The small-volume charging stack in the present application comprises a control cabinet 1, the control cabinet 1 comprises a first shell 9, and a power supply assembly 11 and a plurality of heating components 10 (the heating components 10 refer to structures in the first shell 9 which will generate heat except the power supply assembly 11) arranged in the first shell 9, and a plurality of charging terminals 2 are connected with the power supply assembly 11;the power supply assembly 11 in the charging terminal 2 is integrated into the control cabinet 1, thereby reducing the volume of the charging terminal 2;

[0037] But need to note that, all charging terminal 2 power supply assembly 11 is integrated in the first shell 9, this realizes the centralization of power supply assembly, and when the power supply assembly is centralized in the first shell 9, the power supply assembly and power supply assembly can be reduced by stacking etc., the land area of power supply assembly, in turn, the overall occupation area of charging pile is reduced, this makes the first shell 9 when running, a large amount of heat is generated in the first shell 9, so, more or larger heat dissipation equipment will be set to ensure the smooth operation of the charging pile, but this will significantly increase the volume of the first shell 9;To alleviate this problem, the utility model is equipped with heat conduction layer 8 on the first shell 9, the first shell 9 is uniformly provided with a plurality of heat dissipation holes 7, the liquid cooling heat dissipation assembly includes the first heat dissipation part in the first shell 9, respectively with heating component 10, power supply assembly 11 contact, this makes the first shell 9 in heating component 10 and power supply assembly 11 part of the heat generated can be directly dissipated to the outside through the heat dissipation hole 7 and heat conduction layer 8, to a certain extent, the number of first heat dissipation parts to be arranged is reduced, in turn, the volume of control cabinet 1 is reduced;Furthermore, the power supply assembly 11 and heating assembly in the first shell 9 are arranged close to the first shell 9, which shortens the path required for part of the heat generated by the heating component 10 and the power supply assembly 11 to be dissipated to the outside, reduces the heat accumulation in the first shell 9, improves the heat dissipation effect of the control cabinet 1 itself, further reduces the number of first heat dissipation parts to be arranged, and reduces the volume of the control cabinet 1;And, compared with the air-cooled heat dissipation device, because the specific heat capacity of liquid is greater than that of air, the liquid cooling heat dissipation assembly only needs a small heat dissipation area to achieve the same heat dissipation effect as the air-cooled heat dissipation device, thereby reducing the heat dissipation surface area of the first heat dissipation part, i.e. reducing the volume of the first heat dissipation part, and further reducing the volume of the liquid cooling heat dissipation assembly;In summary, the utility model effectively reduces the volume of the charging terminal 2, the control cabinet 1 and the liquid cooling heat dissipation assembly, i.e. reduces the volume of the charging pile, reduces the occupied space of the charging pile, relieves the interference of the charging pile on the user parking, and improves the parking efficiency in the small volume charging pile parking lot of the utility model.

[0038] The first shell 9 can be cuboid, but is not limited to cuboid. Regardless of the shape of the first shell 9, the first shell 9 can accommodate the power supply assembly 11 and the heat generating component 10. The power supply assembly 11 refers to a device that provides power for the charging terminal 2. According to requirements, the power supply assembly 11 can be a device that provides alternating current and / or direct current. The heat generating component 10 refers to a component in the control cabinet 1 that generates heat in addition to the power supply assembly 11. The heat generating component 10 is not a component that is specifically used for heat generation, but a component that generates heat during operation. The heat generating component 10 and the power supply assembly 11 are arranged close to the first shell 9, which can be understood as the heat generating component 10 and the power supply assembly 11 being closer to the first shell 9 than the central region of the first shell 9, or the power supply assembly 11 and the heat generating component being arranged in an outer region close to the inner wall of the first shell 9 rather than in the central region of the first shell 9. Further, at least one surface of the heat generating component 10 and the power supply assembly 11 is arranged on the first shell 9. In this way, the heat generating component 10 and the power supply assembly 11 are arranged adjacent to the heat dissipation holes 7, which allows part of the heat generated by the heat generating component 10 and the power supply assembly 11 to be dissipated to the outside through the heat dissipation holes 7 without flowing through other regions.

[0039] When the first shell 9 is made of metal such as copper or steel that has good heat conduction performance, the heat conduction layer 8 includes the first shell 9 itself; and / or, the heat conduction layer 8 includes a heat conduction layer 8 arranged on the inner side and / or the outer side of the first shell 9. The heat conduction layer 8 can be made of graphite or a composite of metal, ceramic, polymer or graphite. The charging terminal 2 in the utility model includes a second shell, a plurality of heat generating devices that generate heat during operation are arranged in the second shell, a plurality of heat dissipation holes 7 are uniformly distributed on the second shell, the liquid cooling heat dissipation component includes a plurality of second heat dissipation components arranged in the second shell, the small-size charging pile is located in the parking shed, the side and the top of the control cabinet 1 and the side and the top of the charging terminal 2 are provided with shed plates, the bottom of the control cabinet 1 and the bottom of the charging terminal 2 are provided with support seats, the shed plates can block impurities such as rain and snow from entering the control cabinet 1 and the charging terminal 2 from the side and the top, the support seats are high enough to prevent impurities such as accumulated water and snow on the ground from entering the control cabinet 1 and the charging terminal 2. Based on this, the heat dissipation holes 7 can be arranged on each surface of the first shell 9 and the second shell, thereby improving the heat dissipation effect of the control cabinet 1 and the charging terminal 2 themselves and further reducing the number of liquid cooling heat dissipation components that need to be arranged. However, it should be noted that the arrangement of the heat dissipation holes 7 should not affect the strength required by the first shell 9 and the second shell to ensure the stable support of the control cabinet 1 and the charging terminal 2.

[0040] The charging pile comprises a control cabinet 1 and a plurality of charging terminals 2 connected with the control cabinet 1, wherein each charging terminal 2 is connected with a first controller in the control cabinet 1 through a signal line in addition to being connected with a power supply assembly 11 through a power line, so that the power, power-on / off state and the like of each charging terminal 2 can be adjusted through the first controller in the control cabinet 1.

[0041] The first heat dissipation part comprises a first liquid cooling pipe arranged in the first shell 9 and the second shell, the first liquid cooling pipe is connected with a storage tank, the storage tank stores a working medium, both ends of the first liquid cooling pipe are connected with the storage tank, and a delivery pump is arranged at an input port of the first liquid cooling pipe, so that the working medium at a corresponding temperature can be input into the first liquid cooling pipe through the delivery pump, and the working medium flows and circulates in the first liquid cooling pipe to drive the heat components 10, the heat generating equipment and the power supply assembly 11 to generate heat. The corresponding temperature refers to a temperature that can effectively dissipate heat of the heat components 10, the heat generating equipment and the power supply assembly 11. The working medium can be water, ethylene glycol or silicon oil or other media that can store heat. The first liquid cooling pipe is arranged in the first shell 9 and the second shell to cover all the heat components 10, the heat generating equipment and the power supply assembly 11 that can generate heat. The arrangement of the first liquid cooling pipe in the first shell 9 and the second shell is not limited, and the first liquid cooling pipe can be in a serpentine shape, a U shape or other shapes.

[0042] The liquid cooling heat dissipation assembly further comprises a heat exchange equipment capable of reducing the working medium to a corresponding temperature, and the storage tank can be a cooling tower, so that the heat exchange equipment is the cooling tower itself. When the storage tank itself cannot refrigerate, a refrigerating machine is arranged in or at an output port of the working medium of the storage tank, the refrigerating machine comprises a compressor, a condenser, an evaporator and other components, heat exchange is performed by compressing and expanding the working medium, and finally the temperature of the working medium is reduced to the corresponding temperature.

[0043] In addition, the first liquid cooling pipe can be a flexible pipe, that is, the first liquid cooling pipe is made of a material with a certain flexibility, such as a material with a certain deformation ability, such as PVC. In this way, the first liquid cooling pipe can be arranged in the space gap between the first shell 9 and the second shell, reducing the problem that the first liquid cooling pipe is in a right angle shape at the turning part of the first shell 9 and the second shell and occupies a large space. In addition, the first liquid cooling pipe can be in a flat cross section, that is, in a rectangular shape, so that the first liquid cooling pipe can be arranged in the first shell 9, the second shell, the heat generating assembly, the heat components 10 and the power supply assembly 11, further reducing the occupied space of the first liquid cooling pipe, so that the volume of the first shell 9 and the second shell can be smaller.

[0044] The first liquid cooling pipe is arranged independently of the control cabinet 1 in the region in the first shell 9, that is, the first liquid cooling pipe is arranged in a region in the first shell 9 that is not in communication with a region in the first shell 9, the heat generating component 10, and the power supply assembly 11, thereby reducing the probability of a working medium leakage and a safety accident during operation of the first liquid cooling pipe.

[0045] The small-size charging stack includes a controller, a detection assembly, and an alarm assembly connected to the first liquid cooling pipe. The detection assembly includes a first temperature sensor and a pressure sensor, and the controller is signal-connected to the detection assembly and the alarm assembly. When the controller determines, according to feedback of the detection assembly, that the first liquid cooling pipe has a leakage or an abnormal operating temperature, the controller starts the alarm assembly to remind an operator that the first liquid cooling pipe has a fault, thereby reducing the problem that the control cabinet 1 or the charging terminal 2 needs to be shut down for a long time for maintenance due to a late discovery of a fault of the first liquid cooling pipe. The controller can be specifically arranged in the control cabinet 1 or on a remote server. The alarm assembly can specifically include an audible and visual alarm or a sound alarm arranged around the control cabinet 1 and the charging terminal 2, which reminds the operator to timely maintain the first liquid cooling pipe by emitting an alarm sound or warning light.

[0046] Furthermore, the heat generating component 10 and the power supply assembly 11 in the first shell 9 are arranged in a scattered manner, and the heat generating devices in the second shell are arranged in a scattered manner, which makes the heat generated by the control cabinet 1 and the charging terminal 2 not concentrated in a local region, thereby reducing the local overheating of the control cabinet 1 and the charging terminal 2, and more facilitating heat dissipation of the control cabinet 1 and the charging terminal 2, thereby further reducing the number and volume of the liquid cooling and heat dissipation assemblies. It should be noted that the heat dissipation of the heat generating component 10 and the power supply assembly 11 is arranged in a scattered manner without increasing the volume of the first shell 9, so that there is a gap between the heat generating component 10 and the heat generating component 10 and between the heat generating component 10 and the power supply assembly 11. Similarly, the heat generating devices are arranged in a scattered manner, which means that there is a gap between the heat generating component 10 and the heat generating assembly without increasing the volume of the second shell.

[0047] The first shell 9 and / or the heat generating component 10 and / or the power supply assembly 11 and / or the second shell and / or the heat generating device are connected with a plurality of second temperature sensors, the liquid cooling heat dissipation assembly comprises a delivery pump in communication with the first liquid cooling pipeline, the delivery pump is located at the input end of the first liquid cooling pipeline, the second temperature sensors and the delivery pump are signal connected with the controller, and the delivery pump is used for delivering working medium into the first liquid cooling pipeline; when the controller or the operator determines that the temperature in the first shell 9 reaches a target value according to the feedback of the second temperature sensors, the delivery pump is started; the delivery pump is a pump capable of delivering working medium; the target value refers to the temperature of the control cabinet 1 or the charging terminal 2 reaching the temperature required for heat dissipation; in this way, when the control cabinet 1 and the charging terminal 2 are in a standby state or in a low-temperature environment and the temperature of the control cabinet 1 or the charging terminal 2 is lower than the target value, the liquid cooling heat dissipation assembly can be in a shutdown state, thereby reducing the operation cost of the liquid cooling heat dissipation assembly.

When the charging demand of the electric vehicle waiting for the charging equipment is low, the idle charging terminal 2 in the idle state can be placed into the storage cavity 3, that is, under the ground, by the first driving assembly 4, so that the ground occupation area of the small-size charging pile is reduced; and since the cover plate 5 is arranged on the surface of the storage cavity 3 after the charging terminal 2 is received underground, the area corresponding to the storage cavity 3 on the ground can be used for reversing and steering light parking operations, so that the user can more smoothly complete parking in the parking lot using the small-size charging pile of the utility model.

[0049] The first driving assembly 4 can be a linear driving device such as a pneumatic cylinder or a hydraulic cylinder, and the driving direction of the first driving assembly 4 is arranged along the vertical direction, at this time, the bottom of the charging terminal 2 is provided with a support seat, the charging terminal 2 is fixed on the support seat, the support seat is slidably connected with the side of the storage cavity 3 in the vertical direction, and the first driving assembly 4 is arranged between the bottom of the support seat and the bottom of the storage cavity 3, so that when the charging terminal 2 is in the working state, the first driving assembly 4 can lift the charging terminal 2 out of the storage cavity 3, and when the charging terminal 2 is in the idle state, the first driving assembly 4 can retract the charging terminal 2 into the storage cavity 3.

[0052] In addition, the utility model also is equipped with the isolation layer on the inner wall of storage cavity 3, and the moisture in the ground is prevented from entering the charging terminal 2 through the isolation layer, and the isolation layer can be a waterproof cloth. In addition, when the charging terminal 2 can be stored in the storage cavity 3, the first liquid cooling pipeline, and the signal line, power line and other cables connected between the charging terminal 2 and the control cabinet 1 need to be long enough to meet the requirement that the charging terminal 2 enters the storage cavity 3.

[0053] The entrance of the parking lot is provided with a detection sensor, and the detection sensor is signal connected with the controller; when the controller determines that a vehicle enters the parking lot according to the feedback of the detection sensor, the controller starts a corresponding number of first driving assemblies 4, and the first driving assemblies 4 move the charging terminal 2 to the ground. This makes the user move the charging terminal 2 in the storage cavity 3 to the ground and start the charging terminal 2 before entering the parking space, thereby reducing the problem that the user waits for a long time after reaching the parking space for the charging terminal 2 to rotate out and start. The detection sensor includes a camera and / or an infrared sensor, and a counter.
