Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to a vehicle-mounted sealed charger with heat dissipation function. Background Technology

[0002] With increasing demands for energy conservation and environmental protection, the market share of new energy vehicles is rising year by year. On-board chargers are a crucial component of the power system in new energy vehicles, providing functions such as rectification charging, 12V DC output, and vehicle power distribution. The main heat-generating components inside an on-board charger include power transistors, magnetic components, copper current-carrying devices, capacitors, resistors, fuses, and chips. If the heat from these components is not dissipated for an extended period during operation, it can negatively impact the charger's performance and even cause irreversible damage due to overheating.

[0003] Existing technology, such as the patent with publication number CN218616278U, discloses a vehicle-mounted sealed charger, including a charger body. A heat dissipation layer is installed on the top of the charger body, and two sealing plates are symmetrically mounted on both sides of the top of the heat dissipation layer via hinges. A handle is fixed on the top of the sealing plate. A drive assembly is provided on the back of the charger body to drive the two handles and sealing plates to rotate and open. Under the action of the drive assembly, when the internal temperature of the charger body is too high, the sealing plate is opened, the heat dissipation layer is fully exposed, the space for air flow is increased, the heat dissipation of the machine is accelerated, and the waiting time is shortened. The dust baffles on both sides of the air duct block the dust from entering the heat dissipation layer and the interior of the charger body.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned sealed charger is prone to heat accumulation during long-term use. Therefore, a fan structure can be used to dissipate heat from the top of the charger. However, the fan has a single heat dissipation angle, and the heat from the generator cannot be dissipated evenly. The heat dissipation capacity of the fan alone is limited, causing the heat to still accumulate inside the charger, affecting normal use. To address this, a vehicle-mounted sealed charger with heat dissipation function is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a vehicle-mounted sealed charger with heat dissipation function. It uses multiple sets of copper circulation pipes embedded around the outer frame and flowing coolant, combined with through-type heat dissipation fins and a top fan to form a liquid cooling heat dissipation process, which does not rely on angle issues and makes the overall heat dissipation more uniform.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted sealed charger with heat dissipation function, comprising a main frame, a charging component engaged at the front end of the main frame, the main frame including an outer shell, mounting brackets fixed to both sides of the outer shell, a conduction frame fixed to the top surface of the outer shell, a pump embedded inside one side of the conduction frame, heat dissipation fins fixed inside the conduction frame, circulation pipes passing through the heat dissipation fins, a heat dissipation frame attached to the top surface of the conduction frame, mounting plates fixed to both sides of the heat dissipation frame, and fans distributed on both sides inside the heat dissipation frame.

[0008] Preferably, the circulation pipeline runs evenly around the inside of the outer casing, and the circulation pipeline is made of copper.

[0009] Preferably, the circulation pipeline is connected to the pump, and the circulation pipeline is arranged and run through one side of the heat dissipation fins at equal intervals.

[0010] Preferably, the heat dissipation fins are arranged at equal intervals along the internal slots of the heat conduction frame, and the heat dissipation fins are made of copper.

[0011] Preferably, the heat sink is fixed to the two sides of the conduction frame by mounting plates on both sides, and the fan inside the heat sink is aligned with the center of the conduction frame.

[0012] Preferably, the charging assembly includes a front end plate, a plug-in end fixed to the front end of the front end plate, fasteners distributed at both ends of the front end plate, a charging module fixed to the inner wall of the front end plate, sliding grooves on both sides of the charging module, and a housing frame attached around the charging module.

[0013] Preferably, the charging module is connected to the outer casing via two side grooves to form a sliding structure, and the charging module is fixedly connected to the front end plate and the plug-in terminal.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses multiple sets of copper circulation pipes embedded around the outer shell frame to continuously guide and transfer the heat generated during the internal charging process. It also uses multiple sets of heat dissipation fins fixed at the top for heat conduction. At the same time, it relies on the fan attached to the top surface to form a liquid cooling process. It does not rely on angle issues, making the overall heat dissipation more uniform. In addition, it can maintain the sealing of the internal charging structure while dissipating heat, providing good protection.

[0016] 2. This sealed charger can be unlocked by rotating and unscrewing the fasteners connecting both ends of the front plate. Then, the front plate and the entire charging module can be slid out along the sliding grooves on both sides for inspection and maintenance. It adopts a modular design and a sliding structure for quick removal and placement, making installation and disassembly convenient.

[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment of a vehicle-mounted sealed charger with heat dissipation function includes a main frame 1, a charging component 2 is engaged at the front end of the main frame 1, the main frame 1 includes an outer shell 101, mounting brackets 102 are fixed to both sides of the outer shell 101, a conduction frame 103 is fixed to the top surface of the outer shell 101, a pump 104 is embedded inside one side of the conduction frame 103, heat dissipation fins 105 are fixed inside the conduction frame 103, a circulation pipe 106 passes through the inside of the heat dissipation fins 105, a heat dissipation frame 107 is attached to the top surface of the conduction frame 103, mounting plates 108 are fixed to both sides of the heat dissipation frame 107, and fans 109 are distributed on both sides inside the heat dissipation frame 107.

[0025] like Figure 1-4 As shown, the sealed charger in this utility model is similar in structure to existing sealed chargers, such as the vehicle-mounted sealed charger disclosed in CN218616278U. The main improvement of this utility model lies in the liquid cooling process formed by multiple sets of copper circulation pipes 106 embedded around the outer shell frame 101 and the flowing coolant, combined with the through-type heat dissipation fins 105 and the top fan 109. This eliminates the need to rely on angle issues, making the overall heat dissipation more uniform. In this utility model, the pump 104 and the fan 109 are existing technologies. When using this sealed charger, the user can first turn on the fan 109 and the pump 104. At this time, the pump 104 is driven to circulate the coolant in the connected circulation pipes 106. The coolant is drawn in from one end and discharged from the other, allowing it to circulate around the perimeter of the outer casing 101. This conducts internal heat to the external heat dissipation fins 105. The fan 109 then dissipates the heat conducted by the heat dissipation fins 105 upwards, completing the heat dissipation process. Multiple sets of copper circulation pipes 106 embedded around the perimeter of the outer casing 101 continuously guide and transfer the heat generated during the internal charging process. This, combined with the multiple sets of heat dissipation fins 105 fixed at the top, facilitates heat conduction. Simultaneously, the fan 109 attached to the top surface dissipates heat, forming a liquid cooling process. This eliminates the need to rely on angle issues, resulting in more uniform overall heat dissipation. Furthermore, it maintains the airtightness of the internal charging structure while dissipating heat, providing excellent protection.

[0026] The aforementioned fan 109 is mounted on a heat sink 107. By symmetrically distributing the heat sink 107 on both sides inside the heat sink 107, uniform heat dissipation is achieved for the heat sink 105. Furthermore, the heat sink 107 itself can be detached by the mounting plates 108 on both sides, making it convenient for disassembly, inspection, and maintenance.

[0027] like Figure 1-4 As shown, the charging assembly 2 includes a front end plate 201, with a plug-in end 202 fixed to the front end of the front end plate 201. Fasteners 203 are distributed at both ends of the front end plate 201. A charging module 204 is fixed to the inner wall of the front end plate 201. Sliding grooves 205 are provided on both sides of the charging module 204. A housing frame 101 is attached around the charging module 204. When the device is inspected and maintained, it can be unlocked by rotating and unscrewing the fasteners 203 connected to both ends of the front end plate 201. Then, the front end plate 201 and the entire charging module 204 can be slid out along the sliding grooves 205 on both sides for inspection and maintenance. The charging module 204 and the front end plate 201 adopt a modular design and can be quickly removed and placed with the sliding structure. The installation and disassembly methods are convenient.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
