[0026] In order to have a clearer understanding of the technical features, objects and effects of the utility model, the specific embodiments of the utility model will be described in detail with reference to the drawings.

[0027] As Figure 1 , a schematic diagram of an embodiment structure of a charging machine of the utility model is shown. In Figure 1 an embodiment of the charging machine of the utility model shown, it comprises: a cabinet body 100, a controller 110 and a plurality of compartments 120 arranged in the cabinet body 100; and a power module 160, a heat dissipation device 150 and a temperature detection device 140 arranged in each compartment 120 respectively; the plurality of compartments 120 are isolated from each other, and each compartment 120 forms a heat dissipation channel corresponding to the compartment 120 with the heat dissipation device 150 in the compartment 120; the temperature detection device 140 is used for temperature detection of the compartment 120 to obtain a detection result; the controller 110 is connected with the temperature detection device 140 and the heat dissipation device 150, and is used for outputting a control level according to the detection result of the temperature detection device 140 to control the heat dissipation device 150 corresponding to the compartment 120 to work or not to work.

[0028] Specifically, the charger is designed for the cabinet 100, in the cabinet 100 of the charger, a plurality of mutually isolated compartments 120 are formed by structural design, and a power module 160, a heat dissipation device 150 and a temperature detection device 140 are arranged in each compartment 120. The power module 160 is used to provide power output, and the charger works through the power module 160, that is, the charger supplies power to external equipment through the power module 160 to realize the charging function of the charger on the external equipment. The number of compartments 120 is multiple, and the corresponding power module 160 in the charger can also be understood as multiple. In a specific embodiment, the configuration of each power module 160 can be the same or different. For example, some power modules 160 are configured as power modules with large power output capacity, and the other power modules 160 are configured as power modules with small power output capacity. During the working process of the charger, the number and position of the power modules 160 put into work can be selected according to needs. During the working process of the charger, the power module 160 starts to work and generates heat, which increases the temperature of part of the position in the cabinet 100. The temperature detection device 140 arranged in each compartment 120 can be used for temperature detection of the compartment 120 to confirm the compartment 120 that needs to be cooled, and then the heat dissipation device 150 corresponding to the compartment 120 is controlled to start working to cool the compartment 120. It can be understood that the heat dissipation device 150 and the compartment 120 form a heat dissipation channel corresponding to the compartment 120 in the compartment 120. The heat dissipation channel is used to form a gas flow path in the compartment 120, so that the heat in the compartment 120 can be quickly released to the outside. Through this setting, local cooling can be selected according to needs, without the need to cool the entire device, reducing energy consumption during the cooling process. It can be understood that the process of the controller 110 connecting the temperature detection device 140 to obtain the temperature detection result can be realized according to the existing control chip such as MCU, and the process of the controller 110 controlling the heat dissipation device 150 can also be understood as controlling the heat dissipation device 150 to work or not work by outputting a control level by the MCU. In a specific embodiment, the power-on process of the heat dissipation device 150 can be understood.

[0029] In an embodiment, as shown in Figures 2 to 4 The heat dissipation device 150 includes at least one fan module; the fan module is arranged in the heat dissipation channel to drive the gas to flow in the heat dissipation channel when working. Specifically, in order to accelerate the heat dissipation process in the compartment 120, a corresponding fan module can be arranged in the heat dissipation channel, and the flow speed of the gas in the heat dissipation channel is accelerated through the fan module, so that the compartment 120 is quickly cooled.

[0030] In an embodiment, as shown in Figure 2As shown, the fan module includes a first fan module arranged at the air inlet of the heat dissipation channel, and the first fan module is used to drive external gas to enter the heat dissipation channel through the air inlet. Specifically, the first fan module is arranged at the air inlet of the heat dissipation channel, and the external gas is driven to enter the heat dissipation channel through the first fan module. In the heat dissipation channel, when the entering speed of the gas is accelerated, the corresponding air outlet speed of the air outlet is also accelerated, thereby quickly removing the heat in the chamber 120 and achieving rapid cooling of the chamber 120. The rotating speed of the first fan module can be set or adjusted as needed. The fan data and the number of fan blades included in the first fan module can be selected according to the specific structure of the air inlet.

[0031] In an embodiment, as shown in Figure 3 As shown, the fan module includes a second fan module arranged at the air outlet of the heat dissipation channel, and the second fan module is used to drive the gas in the heat dissipation channel to be discharged from the air outlet. Specifically, the second fan module is arranged at the air outlet of the heat dissipation channel, and the gas in the heat dissipation channel is driven to be quickly discharged from the air outlet through the second fan module. In the heat dissipation channel, when the discharging speed of the gas is accelerated, the corresponding air inlet speed of the air inlet is also accelerated, thereby quickly removing the heat in the chamber 120 and achieving rapid cooling of the chamber 120. The rotating speed of the second fan module can be set or adjusted as needed. The fan data and the number of fan blades included in the second fan module can be selected according to the specific structure of the air outlet.

[0032] In a specific embodiment, the first fan module and the second fan module can be arranged at the same time as needed. That is, the air inlet speed and the air outlet speed are accelerated through the first fan module and the second fan module respectively, so that the flow speed of the gas in the heat dissipation channel is as fast as possible, and rapid cooling of the chamber 120 is achieved.

[0033] In an embodiment, the temperature detection device 140 includes at least one temperature detection probe arranged on the heat dissipation channel. Specifically, the temperature detection process in the chamber 120 can be obtained through the temperature detection probe arranged in the chamber 120, wherein the number of temperature detection probes can be set as needed, for example, temperature detection probes can be arranged at different positions on the heat dissipation channel in the chamber 120 for specific temperature detection. Through the detection process of multiple temperature detection probes, when the chamber 120 is relatively large, the temperature detection result in the chamber 120 can be obtained more accurately. And because the number and position of the temperature detection probes are not suitable, the temperature detection result will not have a large deviation. The temperature detection probe can use the current commonly used temperature detection sensor.

[0034] In an embodiment, the temperature detecting probe includes a first temperature detecting probe arranged near the air inlet of the heat dissipation channel. Specifically, the first temperature detecting probe is arranged near the air inlet of the heat dissipation channel to detect the temperature of the heat dissipation channel by the first temperature detecting probe, and the working process of the heat dissipation device 150 is controlled according to the temperature.

[0035] In an embodiment, the temperature detecting probe includes a second temperature detecting probe arranged near the air outlet of the heat dissipation channel. Specifically, the second temperature detecting probe is arranged near the air outlet of the heat dissipation channel to detect the temperature of the heat dissipation channel by the second temperature detecting probe, and the working process of the heat dissipation device 150 is controlled according to the temperature.

[0036] In a specific embodiment, as shown in Figures 1 to 4 the first temperature detecting probe and the second temperature detecting probe can be arranged simultaneously according to the requirement. The temperature of the warehouse 120 is judged by the temperature detection results of the first temperature detecting probe and the second temperature detecting probe, and then the working process of the heat dissipation device 150 is controlled. The specific temperature judgment process can adopt the commonly used temperature detection process, such as obtaining the average value of multiple temperature values, or obtaining the difference value of multiple temperature values, which is not limited here. The specific control process according to the temperature result can also adopt the commonly used control process, such as setting the threshold value corresponding to the controller 110, and outputting the level according to the relationship between the actual value and the threshold value.

[0037] In an embodiment, as shown in Figure 4 the charger further includes a first dustproof net 171 arranged at the air inlet of the heat dissipation channel, and / or a second dustproof net 172 arranged at the air outlet of the heat dissipation channel. Specifically, the first dustproof net 171 can be arranged at the air inlet of the heat dissipation channel to prevent external dust and foreign matters from entering the warehouse 120 through the air inlet. Similarly, the second dustproof net 172 can also be arranged at the air outlet of the heat dissipation channel to prevent external dust and foreign matters from entering the warehouse 120 through the air outlet. In a specific embodiment, the first dustproof net 171 and the second dustproof net 172 can be arranged simultaneously to achieve complete protection of the warehouse 120.

[0038] In an embodiment, the heat dissipation channel is formed between the outside of the power module 160 and the inside of the warehouse 120. In each warehouse 120, the heat dissipation channel can be directly formed by the outside of the power module 160 and the inside of the warehouse 120. It can be understood that when the power module 160 is arranged in the warehouse 120, the volume of the power module 160 is smaller than the volume of the warehouse 120, and there is a gap between the power module 160 and the inner wall of the warehouse 120. The gap is directly used to form the heat dissipation channel of the warehouse 120, which can realize the maximum volume of the heat dissipation channel in the warehouse 120 and increase the volume of the gas flowing through the heat dissipation channel per unit time.

[0039] In an embodiment, the plurality of chambers 120 are arranged in sequence in the gravity direction of the cabinet 100, and the flow direction of the gas in the heat dissipation channel is perpendicular to the gravity direction. Specifically, the plurality of chambers 120 can be arranged in sequence in the gravity direction of the cabinet 100, and the positions of the air inlet and the air outlet of the heat dissipation channel are arranged so that the flow direction of the gas in the heat dissipation channel is perpendicular to the gravity direction. The air inlet and the air outlet of the heat dissipation channel are arranged on different sides of the cabinet 100, and the heat dissipation channel formed thereby passes through the cabinet 100 in a direction perpendicular to the gravity direction. It can be understood that the flow direction of the gas in the heat dissipation channel in each chamber can be the same. That is, the air inlets of all the heat dissipation channels are arranged on the same side of the cabinet 100, and the air outlets of all the heat dissipation channels are arranged on the same side of the cabinet 100. In an embodiment, as shown in FIG. 1, a separate accommodation space is arranged at the uppermost part of the cabinet 100 to place the controller and related circuits. The accommodation space is adjacent to the first chamber 120, and the controller and related circuits (not shown) are arranged inside the accommodation space. Figure 4 Figure 4

[0040] Optionally, the charging machine further comprises a control panel arranged on the cabinet 100, and the flow direction of the gas in the heat dissipation channel is parallel to the surface on which the control panel is arranged. Specifically, the cabinet 100 of the charging machine is provided with a control panel, wherein the control panel can be understood as an operation panel of the charging machine. The arrangement of the operation panel can be different according to different charging machines. Generally, it can be understood that the surface on which the operation panel of the cabinet 100 is arranged is the front surface, and the air inlet and the air outlet of the heat dissipation channel are arranged on two opposite sides, respectively, so that the flow path of the gas in the heat dissipation channel is parallel to the plane on which the operation panel is arranged.

[0041] Optionally, the controller 110 is further configured to connect the power module 160 and acquire the detection result of the temperature detection device 140 corresponding to the chamber 120 in which the power module 160 is arranged when the power module 160 starts working. Specifically, when the charging machine is working, the controller 110 can also acquire the working state of all the power modules 160, and acquire the temperature detection result of the chamber 120 in which the power module 160 starts working when the power module 160 starts working. Whether the corresponding heat dissipation device 150 needs to be controlled to work is determined according to the temperature detection result. The controller 110 can determine the state of the power module 160 according to the level generated in the working process of the power module 160, and output the corresponding level to acquire the corresponding detection result.

[0042] ​​In a specific embodiment, if the single charger is a 240kW double-gun charging device, 6 power modules of 40kW are used, 2 power modules are grouped to form a power module group 160, and 3 power module groups 160 are obtained, which are respectively arranged in 3 chambers. The double gun can call each module to work according to the actual working condition. When charging, the module group is called randomly, if the power module in a chamber is called and the temperature probe detects that the temperature reaches the threshold value, the fan corresponding to the chamber is started to dissipate heat, and the number of revolutions of the fan and the temperature of the probe need to be in a certain functional relationship. When the temperature decreases to the threshold value, the fan stops.

[0043] Based on the embodiments of the present application, the noise and energy consumption problems caused by the synchronous operation of all fans during the charging process of the charger can be avoided. In the present application, the noise can be effectively reduced by time-sharing work, and the heat dissipation effect is better by the isolated chamber 120 for heat dissipation. The time-sharing work of the fan can also prolong the service life of the fan. The reliability of the whole product is improved.

[0044] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; It should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which belong to the protection scope of the present application; Therefore, any equivalent transformation and modification within the scope of the claims of the present application should belong to the scope of the claims of the present application.
