[0019] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a charging and swapping cabinet capable of quickly cooling batteries includes a cabinet body 1, a controller 2 and multiple charging compartments 3 for placing batteries are provided in the cabinet body 1, and a charging connector connected to the controller 2 is provided in the charging compartment 3; by placing the battery in the charging compartment 3 and connecting the battery to the charging connector, the controller 2 can be used to control the charging connector to be powered on, thereby realizing the function of charging the battery.

[0022] Cabinet 1 is provided with an air inlet duct 4 and an air outlet duct 5. The side walls of charging compartment 3 are provided with an air inlet hole 31 and an air outlet hole 32, respectively. Air inlet hole 31 communicates with air inlet duct 4, and air outlet hole 32 communicates with air outlet duct 5. Cabinet 1 is provided with a cooling air conditioner 6 connected to controller 2. Cooling air conditioner 6 is provided with a return air vent 61 and an air outlet 62. Air outlet 62 communicates with air inlet duct 4, and return air vent 61 communicates with air outlet duct 5. During use, after the battery is placed in the charging compartment 3, the cooling air conditioner 6 is controlled to operate, blowing cold air from the air outlet 62 to the air inlet duct 4, and then flowing into the charging compartment 3 through the air inlet hole 31; the cold air enters the charging compartment 3 to exchange heat with the battery and take away the heat from the battery, and then the hot air flows through the air outlet 32 ​​into the air outlet duct 5, and then flows into the return air port 61 through the air outlet duct 5, and then flows into the cooling air conditioner 6, completing the air circulation process in the charging compartment 3. By controlling the cooling air conditioner 6 to work continuously, the battery temperature can be lowered to an appropriate temperature; after the battery is cooled, the controller 2 controls the charging connector to be powered on, thereby charging the battery.

[0023] This charging and swapping cabinet that can quickly cool down the battery can quickly cool the battery and charge the battery after cooling down; it ensures charging safety and does not require the operator to operate multiple times, reducing the operating steps and thus improving efficiency.

[0024] To further improve efficiency, an exhaust fan 7 is installed on the air inlet 31 of each charging compartment 3. The exhaust fan 7 is used to blow air into the charging compartment 3. During operation, when a battery is placed in a charging compartment 3, the temperature sensor 10 in the charging compartment 3 detects a high temperature. The cooling air conditioner 6 is first controlled to operate, and then the exhaust fan 7 in the corresponding charging compartment 3 is controlled to operate, blowing the cold air in the air inlet duct 4 into the corresponding charging compartment 3 to cool the battery. The exhaust fans 7 corresponding to the charging compartments 3 without batteries are not operated, so that more cold air can enter the charging compartments 3 with batteries, improving the efficiency of cooling the batteries.

[0025] A sealing plate 8 is provided at one end of the air inlet duct 4, which is connected to the cabinet 1 and is used to block the air inlet duct 4. By providing the sealing plate 8, a closed cavity is formed in the air inlet duct 4, which reduces the loss of cold air, reduces energy consumption and improves efficiency.

[0026] An air guide 9 is fixedly mounted on the sealing plate 8 and abuts against the air outlet 62. A trumpet-shaped air guide hole 91 is provided within the air guide 9, which communicates with the air outlet 62 and the air inlet duct 4, respectively. The provision of the air guide 9 ensures that the air outlet 62 of the cooling air conditioner 6 is sealedly connected to the air inlet duct 4, reducing the loss of cold air. During operation, the cooling air conditioner 6 discharges cold air from the air outlet 62, which then passes through the air guide hole 91 and enters the air inlet duct 4. The cold air is then blown into the corresponding charging compartment 3 by the corresponding exhaust fan 7 to cool the battery.

[0027] For ease of control, a temperature sensor 10 is installed in each charging bay 3 and is electrically connected to the controller 2. The temperature sensor 10 is used to detect the temperature within the charging bay 3. During use, when the temperature of the charging bay 3 reaches a suitable charging temperature, the temperature sensor 10 will feedback a signal to the controller 2, which then controls the charging connector to power on and charge the battery. By detecting the temperature of the charging bay 3 through the temperature sensor 10, the controller 2 can control the battery charging in a timely manner.

[0028] In this embodiment, each charging compartment 3 is equipped with a door 11. This door 11 seals off the compartment 3, reducing heat exchange between the compartment 3 and the outside world and improving operational stability. The door 11 is openably connected to the cabinet 1. Opening the door 11 facilitates placement of batteries into the compartment 3; closing the door 11 transforms the compartment 3 into a relatively enclosed cavity.

[0029] The rear end of the cabinet 1 is provided with a rear door 12, which is openably connected to the cabinet 1, and the cooling air conditioner 6 is fixedly mounted on the rear door 12. The rear door 12 is provided to facilitate the installation of the cooling air conditioner 6 on the one hand, and to facilitate the maintenance of the interior of the charging and swapping cabinet on the other hand.

[0030] A supporting foot pad 13 is installed at the lower end of the cabinet body 1, and the supporting foot pad 13 is detachably connected to the cabinet body 1; the supporting foot pad 13 facilitates the placement of the charging and swapping cabinet on the platform so that it can be placed stably; the supporting foot pad 13 adopts a detachable installation method, which makes it easy to move and transport the charging and swapping cabinet after disassembly, thereby improving practicality.

[0031] The lower end of the cabinet 1 is also equipped with multiple casters 14. The installation of the casters 14 facilitates the movement and transportation of the power exchange cabinet, improving its practicality. When it is necessary to move or transport it, the support pads 13 can be removed and the casters 14 can be used for support, thereby facilitating the movement of the cabinet 1 and moving it to the desired location.

[0032] Working principle:

[0033] Under normal circumstances, the charging connector outputs a power-off state; during use, the user opens the cabinet door 11, places the battery into the charging compartment 3, and connects the charging connector to the battery stably; then closes the cabinet door 11. After the cabinet door 11 is closed, the temperature sensor 10 will detect the temperature inside the charging compartment 3. If the temperature exceeds the threshold, the cooling air conditioner 6 will be controlled to work, blowing cold air through the air outlet 62 to the air guide hole 91, and then flowing into the air inlet duct 4 through the air guide hole 91. The cold air is then blown into the corresponding charging compartment 3 through the corresponding exhaust fan 7 to cool the battery. The cold air enters the charging compartment 3 for heat exchange, taking away the heat inside the charging compartment 3. The hot air flows into the outlet duct 5 through the air outlet 32, and then flows into the return air port 61 through the outlet duct 5, and then flows into the cooling air conditioner 6, realizing a circulation process of air circulation in the charging compartment 3. By controlling the cooling air conditioner 6 to work continuously, the temperature of the battery can be lowered to a suitable temperature; when the temperature sensor 10 detects that the temperature of the charging compartment 3 has reached a temperature suitable for charging, it will feedback a signal to the controller 2, and then control the charging connector to power on, thereby realizing the function of charging the battery.

[0034] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
