Description

Technical Field

[0002] A charger is a device used to provide electrical energy to batteries or other rechargeable devices. It is widely used in electric vehicles, power tools, portable electronic devices, industrial equipment and other fields.

[0003] Chargers generate heat during operation, especially during high-power charging, which can lead to overheating, affecting performance, shortening lifespan, and even causing safety issues. Therefore, to ensure normal operation, chargers need heat dissipation protection. Existing chargers typically use cooling fans to cool the internal components. However, using cooling fans can easily introduce impurities and moisture from the air into the charger. Over time, this can negatively impact the charger's performance, affecting its lifespan and heat dissipation efficiency.

[0004] Therefore, we propose a charger with a dual-cavity structure housing to solve the above problems. Utility Model Content

[0020] Beneficial effects

[0021] Compared with the prior art, this utility model provides a charger with a dual-cavity structure shell, which has the following advantages:

[0022] 1. This utility model, through its design, brings the following benefits to the overall operation: By setting up the charger housing, and with the spacing of the heat dissipation aluminum plate, the charger housing is divided into two chambers: a sealed chamber and a ventilated chamber. This achieves functions such as heat dissipation and safety protection during the charging process, prevents dust and moisture from entering the power module, protects the internal circuitry of the sealed chamber from contamination and corrosion, greatly reduces the product failure rate, makes the product performance more stable, extends the service life of the charger housing and its internal circuitry modules, and ensures normal operation in different environments.

[0023] 2. This utility model, through its design, brings the following benefits to the overall operation: The sealed cavity and ventilation cavity design achieve a fully sealed design by installing the circuit module inside the sealed cavity, while the ventilation cavity houses the heat dissipation aluminum plate. A cooling fan and heat dissipation fins work together to dissipate the heat generated by the aluminum plate. The cooling fan is positioned on the aluminum plate, and the heat dissipation fins are positioned around the fan.

[0034] Example

[0035] Please refer to Figures 1 to 5 As shown:

[0036] To address the problems mentioned in the technical solutions, this application provides a charger with a dual-cavity structure housing, including a charger housing 1, a back plate 2 connected to the back of the charger housing 1, a switch 3 connected to the back plate 2, a control panel 7 connected to the charger housing 1, a heat dissipation aluminum plate 8 vertically arranged inside the charger housing 1, a partition plate 5 arranged on the outside of the heat dissipation aluminum plate 8, the partition plate 5 being U-shaped, and the heat dissipation aluminum plate 8 and the inner edge of the partition plate 5 being connected to form a complete panel; the panel divides the interior of the charger housing 1 into two independent cavities, the panel and the front part of the charger housing 1 forming a sealed cavity 4, and the panel, the charger housing 1, and the back plate 2 forming a ventilation cavity 6;

[0037] A circuit module is installed inside the sealed cavity 4, and the circuit module is connected to the heat dissipation aluminum plate 8;

[0038] A cooling fan 10 is installed inside the ventilation cavity 6 and is connected to the heat dissipation aluminum plate 8; heat dissipation fins 9 are provided around the cooling fan 10 and are connected to the heat dissipation aluminum plate 8.

[0039] The heat dissipation fins 9 are arc-shaped, and the bending direction of the heat dissipation fins 9 is the same as the rotation direction of the cooling fan 10.

[0040] The circuit module and the cooling fan 10 are symmetrically arranged around the center of the heat dissipation aluminum plate 8.

[0041] Multiple screw holes 13 are provided around the heat dissipation aluminum plate 8, and the heat dissipation aluminum plate 8 is bolted to the partition plate 5 through the screw holes 13.

[0042] The partition 5 is made of the same material as the charger housing 1.

[0043] A sealing strip made of elastic sealing material is provided at the connection between the charger housing 1 and the heat dissipation aluminum plate 8, and at the connection between the heat dissipation aluminum plate 8 and the partition plate 5.

[0044] The charger housing 1 has heat dissipation holes 11 on all four sides of the ventilation cavity 6.

[0045] The charger housing 1 has handle holes 12 on both sides of its outer wall.

[0046] An input power cord 14 is provided on one side of the bottom of the charger housing 1.

[0047] An output power line 15 is provided on one side of the input power line 14.

[0048] Among them, the cooling fan 10 is used to provide forced air cooling for the heat dissipation fins 9.

[0049] The cooling fan 10 is connected to an external controller.

[0050] The cooling fan 10 can be installed in a suitable position according to the actual structural requirements to ensure the air cooling effect.

[0051] The heat generated by the circuit module is transferred to the heat dissipation fins 9 through the heat dissipation aluminum plate 8, and then dissipated to the external environment by the heat dissipation fan 10.

[0052] Working principle:

[0053] When in use, the external power supply and the device being charged are connected through the input power line 14 and the output power line 15 at the bottom of the charger housing 1. The operator starts the device through the switch 3 on the back panel 2. The current enters the charger through the input power line 14 and first undergoes preliminary overcurrent and overvoltage protection through the protection unit of the circuit module inside the sealed cavity 4.

[0054] After the charger is started, the control panel 7 displays the initialization status. The circuit module performs a self-test on the core components, including the start / stop function of the cooling fan 10, the sealing status of the sealed cavity 4, and the integrity of the circuit connection. After the self-test is passed, the control panel 7 displays the ready status and enters the charging mode.

[0055] During the charging process, the heat generated by the circuit module is transferred to the heat dissipation aluminum plate 8 through heat conduction. Since the circuit module and the cooling fan 10 are centrally symmetrically arranged, the heat is evenly distributed on the heat dissipation aluminum plate 8.

[0056] The cooling fan 10 inside the ventilation cavity 6 starts and generates directional airflow. Since the cooling fins 9 are arc-shaped and the bending direction is consistent with the rotation direction of the cooling fan 10, the airflow flows smoothly along the arc of the fins, reducing turbulence and noise. When the airflow passes through the cooling fins 9, it carries away the heat and is discharged to the outside space through the heat dissipation holes 11 around the charger housing 1.

[0057] Furthermore, the connection between the heat dissipation aluminum plate 8 and the charger housing 1, and the connection between the heat dissipation aluminum plate 8 and the partition plate 5 are both provided with sealing strips of elastic sealing material to ensure the airtightness of the sealed cavity 4, prevent the airflow in the ventilation cavity 6 from carrying dust and moisture into the sealed cavity 4, and protect the circuit module from contamination.

[0058] After the circuit module stops outputting, the cooling fan 10 continues to run for a preset time until the temperature inside the ventilation cavity 6 drops to a safe range and then automatically stops; the control panel 7 displays charging completion information, and the operator turns off the device via switch 3, completing the entire workflow.

[0059] By setting up the charger housing 1, and with the spacing effect of the heat dissipation aluminum plate 8, the charger housing 1 is divided into two chambers: a sealed cavity 4 and a ventilated cavity 6. This achieves functions such as heat dissipation and safety protection during the charging process, prevents dust and moisture from entering the power module, protects the internal circuitry of the sealed cavity 4 from contamination and corrosion, greatly reduces the product failure rate, makes the product performance more stable, extends the service life of the charger housing 1 and its internal circuit modules, and ensures normal operation in different environments.

[0060] Through the design of the sealed cavity 4 and the ventilation cavity 6, the circuit module is installed in the sealed cavity 4 to achieve a fully sealed design, and the heat dissipation aluminum plate 8 is installed in the ventilation cavity 6. The heat dissipation fan 10 and heat dissipation fins 9 work together to dissipate the heat generated by the heat dissipation aluminum plate 8. The heat dissipation fan 10 is set on the heat dissipation aluminum plate 8, and the heat dissipation fins 9 are set around the heat dissipation fan 10. Compared with the opposite placement of the heat dissipation fins 9 and the heat dissipation fan 10 in the prior art, it can better avoid the airflow directly impacting the heat dissipation fins 9, and reduce the generation of air turbulence and noise. At the same time, the air flow speed is increased, which accelerates the heat dissipation of the heat dissipation fins 9, thereby reducing the surface temperature of the heat dissipation aluminum plate 8 and carrying away the heat generated by the circuit module that is attached to the heat dissipation aluminum plate 8 in the sealed cavity 4, ensuring that the heat generated during the charging process can be dissipated in a timely manner.

[0061] The circuit module and the cooling fan 10 are symmetrically arranged along the center of the heat dissipation aluminum plate 8, so that the heat generated by the circuit module is concentrated and transferred to the center of the cooling fan 10, thereby improving the overall heat dissipation performance of the product. At the same time, both the circuit module and the cooling fan 10 are set on the heat dissipation aluminum plate 8, and the heat dissipation aluminum plate 8 is connected to the partition plate 5 by bolts, which facilitates maintenance or overall replacement in case of failure, improves maintenance efficiency and reduces maintenance costs.
