Description

Technical Field

[0001] This utility model relates to the field of battery swapping cabinet technology, specifically to a novel intelligent battery swapping cabinet with heat dissipation function. Background Technology

[0002] In the hustle and bustle of urban life, electric vehicles have become an indispensable means of transportation for many. However, the range of electric vehicles has always been a key concern for users. To address this issue, battery swapping stations have emerged, offering electric vehicle users an unprecedentedly convenient experience with their intelligent battery replacement services.

[0003] Currently, when existing outdoor battery swapping cabinets are in operation during the summer, the surface temperature of the cabinet rises rapidly after absorbing solar radiation. At the same time, the battery charging process generates a lot of heat, causing the temperature inside the cabinet to reach about 70 degrees Celsius, which is quite dangerous. Although cooling fans are installed on the side walls of the battery swapping cabinet, traditional side wall fans can only turbulentize local areas and cannot form an effective airflow, resulting in unsatisfactory cooling effects. Utility Model Content

[0004] The purpose of this invention is to provide a novel intelligent battery swapping cabinet with heat dissipation function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel intelligent battery swapping cabinet with heat dissipation function, comprising:

[0006] The cabinet has multiple battery compartments installed from top to bottom on the left and right sides of its internal cavity, and multiple charging power supplies installed from left to right on the upper part of its internal cavity. The cabinet also has a temperature sensor and a controller installed inside, and air inlets are provided on the lower parts of both the left and right sides of the cabinet.

[0007] The heat dissipation mechanism includes an exhaust fan, a heat absorption cover, and two heat dissipation pipes. The heat absorption cover is located above the multiple charging power supplies. The two heat dissipation pipes are respectively fixed to the inner walls of the left and right sides of the cabinet. The exhaust fan is installed on the top of the cabinet. The suction end of the exhaust fan extends into the cabinet and is connected to the heat absorption cover by a first heat absorption pipe. The suction end of the exhaust fan is connected to the heat dissipation pipes by a second heat absorption pipe. The heat dissipation pipes are connected to the corresponding battery compartments by heat absorption branch pipes.

[0008] Furthermore, the controller is electrically connected to the temperature sensor and the exhaust fan.

[0009] Furthermore, a protective housing is fitted around the outside of the exhaust fan, and an exhaust port is provided on the protective housing. The output end of the exhaust fan is connected to the exhaust port.

[0010] Both the air inlet and outlet are equipped with dust filters to reduce dust entering the cabinet and lower the failure rate of batteries and power supplies.

[0011] Furthermore, the inner cavity of the heat-absorbing branch pipe is connected to the inner cavity of the battery compartment. The battery compartment has multiple air inlet holes at equal intervals on the side away from the heat-absorbing branch pipe. Hot air is quickly drawn away by the heat-absorbing branch pipe, and cold air enters the battery compartment through the air inlet holes.

[0012] Furthermore, the heat dissipation pipe is made of aluminum alloy and has a rectangular cross-section.

[0013] Furthermore, the contact surface between the inner wall of the cabinet and the heat dissipation pipe is coated with a thermally conductive silicone grease layer, which improves the heat conduction effect between the cabinet and the heat dissipation pipe.

[0014] Furthermore, the heat-absorbing branch pipe is a flexible heat-resistant hose, which can be finely adjusted according to the position of the battery compartment to avoid assembly stress. A one-way valve is installed on the heat-absorbing branch pipe to prevent hot air backflow when the machine is stopped. The heat-absorbing cover has a horn-shaped structure, with the large end of the heat-absorbing cover facing the charging power supply and the small end of the heat-absorbing cover connected to the first heat-absorbing pipe. The horn-shaped heat-absorbing cover expands the heat absorption area and reduces wind speed loss, thereby improving the efficiency of capturing the top heat source.

[0015] Furthermore, the top of the cabinet is equipped with a sunshade and rainproof cover, and the protective box is located below the sunshade and rainproof cover. The sunshade and rainproof cover completely covers the protective box, cabinet and exhaust vent to prevent rainwater erosion and direct sunlight from causing the cabinet to heat up.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By setting up an exhaust fan, heat absorption cover, heat dissipation pipe, first heat absorption pipe, second heat absorption pipe and heat absorption branch pipe, the heat on the charging power supply and the heat inside the battery compartment can be quickly dissipated, thereby achieving synchronous and rapid cooling of the charging power supply and the battery compartment.

[0018] 2. The heat absorption branch pipe is a flexible heat-resistant hose. The flexible heat-resistant hose can be finely adjusted according to the position of the battery compartment to avoid assembly stress. A one-way valve is installed on the heat absorption branch pipe to prevent hot air backflow when the machine is stopped. At the same time, the exhaust fan will prevent hot air from lingering in the cabinet. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 3 The novel intelligent battery swapping cabinet with heat dissipation function shown includes:

[0027] Cabinet 1, multiple battery compartments 2 are installed in the left and right sides of the inner cavity of cabinet 1 from top to bottom, multiple charging power supplies 3 are installed in the upper part of the inner cavity of cabinet 1 from left to right, temperature sensor 4 and controller 5 are installed inside cabinet 1, and air inlets 6 are opened in the lower part of both the left and right sides of cabinet 1.

[0028] The heat dissipation mechanism includes an exhaust fan 7, a heat absorption cover 8, and two heat dissipation pipes 9. The heat absorption cover 8 is located above multiple charging power supplies 3. The two heat dissipation pipes 9 are respectively fixed to the inner walls of the left and right sides of the cabinet 1. The exhaust fan 7 is installed on the top of the cabinet 1. The suction end of the exhaust fan 7 extends into the cabinet 1 and is connected to the heat absorption cover 8 by a first heat absorption pipe 10. The suction end of the exhaust fan 7 is connected to the heat dissipation pipes 9 by a second heat absorption pipe 11. The heat dissipation pipes 9 are connected to the corresponding battery compartments 2 by heat absorption branch pipes 12.

[0029] The controller 5 is electrically connected to the temperature sensor 4 and the exhaust fan 7.

[0030] The exhaust fan 7 is fitted with a protective housing 13, and an exhaust port 14 is provided on the protective housing 13. The output end of the exhaust fan 7 is connected to the exhaust port 14.

[0031] Dust filters are installed inside both the air inlet 6 and the air outlet 14. The dust filters reduce the amount of dust entering the cabinet 1 and reduce the failure rate of the battery and power supply.

[0032] The inner cavity of the heat-absorbing branch pipe 12 is connected to the inner cavity of the battery compartment 2. Multiple air inlet holes 15 are equally spaced on the side of the battery compartment 2 away from the heat-absorbing branch pipe 12. Hot air is quickly drawn away by the heat-absorbing branch pipe 12, and cold air enters the battery compartment 2 through the air inlet holes 15.

[0033] The top of the cabinet 1 is equipped with a sunshade and rainproof cover 16, and the protective box 13 is located below the sunshade and rainproof cover 16. The sunshade and rainproof cover 16 completely covers the protective box 13, the cabinet 1 and the exhaust vent 14 to prevent rainwater erosion and direct sunlight from causing the cabinet 1 to heat up.

[0034] In this invention, temperature sensor 4 detects the temperature inside cabinet 1. When the temperature inside cabinet 1 exceeds the value set by temperature sensor 4, temperature sensor 4 sends a signal to controller 5. Controller 5 controls exhaust fan 7 to work. Exhaust fan 7 directly extracts hot air above charging power supply 3 through first heat absorption pipe 10 and heat absorption cover 8. At the same time, exhaust fan 7 extracts hot air from heat dissipation pipe 9 through second heat absorption pipe 11, creating a negative pressure inside heat dissipation pipe 9. It also extracts hot air from each battery compartment 2 through multiple heat absorption branch pipes 12. External cold air enters cabinet 1 through air inlet 6, forming a cooling airflow from bottom to top to cool the charging power supply 3. At the same time, some of the cold air entering cabinet 1 enters battery compartment 2 through air inlet vent 15 on battery compartment 2 to cool the power supply inside battery compartment 2. The hot air extracted by exhaust fan 7 is discharged through exhaust vent 14 on protective housing 13.

[0035] like Figure 2 As shown, the heat dissipation pipe 9 is made of aluminum alloy and has a rectangular cross-section.

[0036] The contact surface between the inner wall of cabinet 1 and the heat dissipation pipe 9 is coated with a layer of thermally conductive silicone grease.

[0037] The heat-absorbing branch pipe 12 is a flexible heat-resistant hose. A one-way valve is installed on the heat-absorbing branch pipe 12. The heat-absorbing cover 8 has a horn-shaped structure. The large end of the heat-absorbing cover 8 faces the charging power supply 3, and the small end of the heat-absorbing cover 8 is connected to the first heat-absorbing pipe 10.

[0038] In this invention, the thermally conductive silicone grease layer between the heat dissipation pipe 9 and the inner wall of the cabinet 1 improves the heat conduction effect between the cabinet 1 and the heat dissipation pipe 9. The heat-absorbing branch pipe 12 is a flexible heat-resistant hose. The flexible heat-resistant hose can be finely adjusted according to the position of the battery compartment 2 to avoid assembly stress. The one-way valve on the heat-absorbing branch pipe 12 can prevent hot air backflow when the machine is stopped. The horn-shaped heat-absorbing cover 8 expands the heat absorption area and reduces wind speed loss, thereby improving the efficiency of capturing the top heat source.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
