[0061] Preferably, the electric door comprises a plurality of rotating blades;

[0062] The plurality of rotating blades and the second air outlet 102 form a shutter structure.

[0063] Preferably, the fan 11 is a speed-adjustable fan.

[0064] The second aspect of the present invention provides a power exchange cabinet 2, comprising:

[0065] Any heat dissipation component 1 of the battery exchange cabinet in the first aspect.

[0066] Preferably, it also includes:

[0067] N independent charging bays 21 arranged in an array;

[0068] The N second air vents 102 are respectively opened on the side walls of the N charging compartments 21 .

[0069] Preferably, it also includes:

[0070] N charge controllers 22;

[0071] N charging controllers 22 are disposed in the heat dissipation channel 12 and correspond to the N charging compartments 21 respectively.

[0072] Preferably, the charging compartments 21 are arranged in K rows and K columns, where K*k=N, and K≥2;

[0073] There are heat dissipation channels 12 between the charging compartments 21 in adjacent rows;

[0074] The second air vent 102 is formed on a side wall of the charging compartment 21 near the heat dissipation channel 12 .

[0075] Preferably, the charging compartment 21 is provided with a power outlet 201;

[0076] The side wall of the charging compartment 21 opposite to the power outlet 201 is provided with a plurality of heat dissipation holes 202;

[0077] A rain canopy 23 is provided on the outer side of the heat dissipation hole 202 .

[0078] Example 1

[0079] See also Figures 1 to 5 A heat dissipation assembly 1 for a power exchange cabinet provided in the first embodiment of the present invention includes: a fan 11 and a heat dissipation channel 12; the heat dissipation channel 12 is provided with a first air outlet 101 and N second air outlets 102, where N is an integer greater than or equal to 2; the first air outlet 101 is connected to the input end or the output end of the fan 11.

[0080] It should be noted that: the fan 11 is used to form an air pressure difference between the first air outlet 101 and the multiple second air outlets 102, accelerate the air flow, and thus remove the heat generated in the charging compartment 21 of the battery swap cabinet; the heat dissipation channel 12 is used to connect the multiple charging compartments 21 with the input end or output end of the fan 11, wherein the multiple second air outlets 102 are respectively opened in the multiple charging compartments 21 of the battery swap cabinet; when the first air outlet 101 is connected to the output end of the fan 11, the air pressure of the first air outlet 101 is greater than the air pressure of the second air outlet 102, that is, the heat is dissipated by "blowing", and the air with lower temperature flows into the heat dissipation channel 12 through the first air outlet 101 under the drive of the fan 11, and then enters the charging compartment through the second air outlet 102 21, the air with higher temperature in the charging compartment 21 is forced out of the charging compartment 21. At this time, the second air outlet 102 is the air inlet of the heat dissipation channel 12, and the first air outlet 101 is the air outlet of the heat dissipation channel 12; when the first air outlet 101 is connected to the input end of the fan 11, the air pressure of the first air outlet 101 is less than the air pressure of the second air outlet 102, that is, the heat is dissipated by "suction". Under the action of the air pressure difference, the high-temperature air in the charging compartment 21 flows into the heat dissipation channel 12 through the second air outlet 102, and finally enters the input end of the fan 11 through the first air outlet 101 and is sent out of the battery swap cabinet. At this time, the first air outlet 101 is the air outlet of the heat dissipation channel 12, and the second air outlet 102 is the air inlet of the heat dissipation channel 12.

[0081] There is no specific limitation on the shape of the heat dissipation channel 12, which needs to be designed according to the shape of the power exchange cabinet. It can be enclosed by the cabinet body of the power exchange cabinet, or it can be in the form of a pipe independent of the cabinet body. It is necessary to ensure that the heat dissipation channel 12 has high air tightness except for the first air outlet 101 and the second air outlet 102 to ensure that a stable air pressure difference can be formed; the shape and size of the first air outlet 101 and the second air outlet 102 are not specifically limited here, and it is sufficient to ensure smooth air circulation. The first air outlet 101 is connected to the input or output end of the fan 11, that is, the first air outlet 101 is in an air field that is obviously affected by the fan 11. The preferred method is to let the input or output end of the fan 11 face the first air outlet 101, or the fan 11 can be directly set at the first air outlet 101.

[0082] Beneficial effects of this embodiment:

[0083] By setting a first air outlet 101 and N second air outlets 102 in the heat dissipation channel 12, since the first air outlet 101 is connected to the output end of the fan 11, when the fan 11 is running, the air pressure of the first air outlet 101 is less than the air pressure of the second air outlet 102, and the heat generated in the multiple charging compartments 21 of the power exchange cabinet flows into the heat dissipation channel 12 through the corresponding second air outlet 102 under the action of the air pressure difference, and then flows from the heat dissipation channel 12 to the first air outlet 101, and the heat is drawn out of the power exchange cabinet by the fan 11; or since the first air outlet 101 is connected to the input end of the fan 11, when the fan 11 is running, the air pressure of the first air outlet 101 is less than the air pressure of the second air outlet 102, and the heat generated in the multiple charging compartments 21 of the power exchange cabinet passes through the corresponding second air outlet 102 under the action of the air pressure difference, and then flows from the heat dissipation channel 12 to the first air outlet 101, and the heat is drawn out of the power exchange cabinet by the fan 11; 1 When the fan 11 is in operation, the air pressure of the first air outlet 101 is greater than the air pressure of the second air outlet 102. Under the action of the air pressure difference, the air at the input end of the fan 11 flows from the first air outlet 101 to the heat dissipation channel 12, and then enters different charging compartments of the battery swap cabinet through different second air outlets 102. The heat in the charging compartment 21 is blown out of the battery swap cabinet by the fan 11; since the number of first air outlets 101 is only one, the air pressure difference required for heat dissipation can be created by setting a smaller number of fans 11, and heat dissipation of multiple charging compartments is achieved by fewer fans 11, thereby reducing the manufacturing cost and use cost of the battery swap cabinet.

[0084] Specifically, in order to reduce the electricity cost of the battery swap cabinet, a temperature sensor is provided at the second air outlet 102; the temperature sensor is connected to the control center signal of the fan 11. The temperature sensor is used to detect the temperature value at the second air outlet 102, that is, the real-time temperature in the charging compartment of the battery swap cabinet. When the temperature value detected by any temperature sensor exceeds the preset threshold, it means that there is a charging compartment that needs heat dissipation. The control center controls the fan 11 to turn on for heat dissipation. When the temperature values at N second air outlets 102 are all lower than the preset threshold, it means that the temperature of all charging compartments is normal and no heat dissipation is required. The control center controls the fan 11 to remain on standby. In this way, the fan 11 is started for heat dissipation when heat dissipation is needed, which avoids the fan 11 being in the started state for a long time, thereby saving electricity.

[0085] Optimized: Fan 11 is an adjustable-speed fan. Fan 11 adjusts its speed based on the temperature at the second air outlet 102. That is, the higher the temperature of the charging compartment 21, the faster the fan 11 speed. This allows for rapid reduction in the temperature within the battery swap cabinet, ensuring that charging efficiency is not affected while also avoiding charging failures. Because the temperature sensor is signal-connected to the fan 11 control center, when the temperature at the second air outlet 102 reaches a point where speed regulation is required, the control center controls the fan 11 speed.

[0086] Specifically, in order to achieve precise heat dissipation of the charging compartment 21 and improve the heat dissipation efficiency of the heat dissipation component 1 of the power exchange cabinet, an electric door is provided at each second air outlet 102; the electric door is connected to a temperature sensor. The electric door controls its own opening and closing according to the temperature collected by the temperature sensor. When the temperature value at the corresponding second air outlet 102 exceeds the preset threshold, the corresponding electric door opens to allow the corresponding charging compartment 21 to communicate with the heat dissipation channel 12; when the temperature value at the corresponding second air outlet 102 is lower than the preset threshold, the corresponding electric door closes; the size and shape of the electric door are determined according to the size and shape of the second air outlet 102, so that when the electric door is closed, the electric door can cover the second air outlet 102, and when the electric door is open, the electric door can open to allow the heat dissipation channel 12 to communicate with the corresponding charging compartment 21 through the second air outlet 102. In this way, only the charging compartment 21 that needs heat dissipation is dissipated, thereby improving the heat dissipation efficiency.

[0087] For example, the electric door includes multiple rotating blades, which together with the second air vents 102 form a shutter structure. When the temperature at the corresponding second air vents 102 exceeds a preset threshold, the multiple rotating blades rotate in a certain direction to open, allowing the heat dissipation channel 12 to communicate with the corresponding charging compartment 21. When the temperature at the corresponding second air vents 102 falls below the preset threshold, the multiple rotating blades rotate in the opposite direction to close, isolating the heat dissipation channel 12 from the corresponding charging compartment 21.

[0088] Example 2

[0089] See also Figures 2 to 9 A power exchange cabinet 2 provided in the second embodiment of the present invention includes: any power exchange cabinet heat dissipation component 1 provided in the first embodiment.

[0090] It should be noted that the battery swap cabinet 2 includes a battery swap cabinet heat dissipation component 1, so that the battery swap cabinet 2 can achieve the effect of reducing the temperature inside the battery swap cabinet 2 through the battery swap cabinet heat dissipation component 1; the battery swap cabinet 2 can be any common battery swap cabinet on the market.

[0091] Specifically, to address the issues of battery storage and the placement of the second air vents 102, the battery swap cabinet further comprises: N independent charging compartments 21 arranged in an array; N second air vents 102 are respectively provided on the side walls of the N charging compartments 21. The charging compartments 21 are used to store and charge batteries; the second air vents can be provided on any side wall of the charging compartments 21, ensuring that the batteries do not interfere with the second air vents 102 connecting the charging compartments 21 with the heat dissipation channel 12.

[0092] It should be noted that: according to the actual usage of the user, a battery pad 211 can be set in the charging compartment 21. The battery pad 211 is used to fix the battery so that the battery can be stably located in the charging compartment 21, avoiding external impact on the battery swap cabinet 2, affecting the stability of battery storage and the safety of the battery swap cabinet 2; the number of battery pads 211 is determined according to the number of charging compartments 21 and the shape of the battery, so as to achieve the purpose of fixing the battery. For example, if there are 12 charging compartments 21 and the battery is in the shape of a cube, there are 24 battery pads 211, and two battery pads 211 are provided at the bottom of each charging compartment 21 to maintain the stability of the battery in the charging compartment 21; the battery pad 211 is connected to the charging compartment 21 in any conventional manner, such as welding, gluing, etc.

[0093] Specifically, the battery swap cabinet is further provided with N charging controllers 22 corresponding to the N charging compartments 21. In order to achieve heat dissipation of the charging controllers 22, the N charging controllers 22 are arranged in the heat dissipation channel 12. In this way, the charging controller 22 controls the heat generated during battery charging to flow through the heat dissipation channel 12 to the first air outlet 101 or the second air outlet 102, and finally to the outside of the battery swap cabinet 2, thereby achieving heat dissipation of the charging compartments 21 and the charging controller 22 at the same time.

[0094] Specifically, the charging compartments 21 are arranged in K columns and k rows, where K*k=N, K≥2; there is a heat dissipation channel 12 between the charging compartments 21 in adjacent columns, that is, the heat dissipation channel 12 is enclosed by the cabinet itself; the second air outlet 102 is opened on the side wall of the charging compartment 21 close to the heat dissipation channel 12. The number of columns and rows of the charging compartments 21 is determined according to actual usage. For example, if the charging compartments 21 are arranged in 2 columns and 6 rows, the number of charging compartments 21 is 12; the heat dissipation channel is a square channel extending in the up and down directions, which is enclosed by the relative outer walls of the charging compartments 21 in adjacent columns and the front and rear walls of the battery exchange cabinet. For example, if the charging compartments 21 are arranged in 2 columns and 6 rows, a square heat dissipation channel 12 is enclosed between the 2 columns of charging compartments 21. The top of the heat dissipation channel 12 is level with the top of the first row of charging compartments 21, and the bottom of the heat dissipation channel 12 is level with the bottom of the sixth row of charging compartments 21. The fan 11 is set at the top of the heat dissipation channel 12, and the charging controller 22 corresponding to the left column of charging compartments 21 is set on the left wall of the heat dissipation channel 12 and corresponds to the corresponding charging compartment 21. The charging controller 22 corresponding to the right column of charging compartments 21 is set on the right wall of the heat dissipation channel 12 and corresponds to the corresponding charging compartment 21.

[0095] Specifically, the charging compartment 21 is provided with a power outlet 201, and each power outlet 201 is provided with a rotating power door 24. To ensure that the charging compartment 21 is connected to the external environment and to exchange air, a plurality of heat dissipation holes 202 are provided on the side wall of the charging compartment 21 opposite the power outlet 201. A canopy 23 is provided on the outside of the heat dissipation hole 202. The heat dissipation hole 202 is used to allow air from the external environment to flow into the charging compartment 21, or to allow high-temperature air in the charging compartment 21 to be discharged to achieve heat dissipation. The number of heat dissipation holes 202 is determined according to the heat dissipation requirements of the heat exchange cabinet. The canopy 23 is used to shelter the heat dissipation holes 202 from rain. The shape and size of the canopy 23 are determined according to the size of the heat dissipation holes 202 to ensure that rainwater is prevented from entering the heat dissipation holes 202. The number of the canopy 23 is the same as the number of the heat dissipation holes 202.
