Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation systems, and in particular to a heat dissipation system suitable for small-capacity energy devices. Background Art

[0002] Small-capacity energy generally refers to devices or technologies that can provide relatively small power and energy storage, and are suitable for scenarios such as portable electronic devices, emergency backup power supplies, and small electronic products. The following are several common small-capacity energy devices or technologies: lithium batteries, nickel-metal hydride batteries, alkaline batteries, etc.

[0003] A lithium battery charging cabinet is a device designed specifically for charging and managing lithium batteries, usually designed for commercial, industrial or personal use.

[0004] Lithium battery charging cabinets are widely used in modern life, especially in mobile electronic devices, portable tools and outdoor equipment, providing convenient, safe and efficient lithium battery management and charging solutions.

[0005] When lithium batteries are charging, they generate heat. Traditional lithium battery charging cabinets can dissipate heat when lithium batteries are charging. However, there is a risk of fire when lithium batteries are charging, posing a safety hazard.

[0006] In summary, the prior art lacks the technology for fire monitoring and fire handling when a certain lithium battery charging cabinet is charging lithium batteries. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the background technology and propose a heat dissipation system suitable for small-capacity energy devices.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is: a heat dissipation system suitable for small-capacity energy devices, including a lithium battery charging cabinet, a heat dissipation fan is fixedly connected to the rear side of the lithium battery charging cabinet, a heat conduction mechanism is fixedly connected to the inside of the lithium battery charging cabinet, lithium batteries are placed in the lithium battery charging cabinet, a pushing mechanism is slidably provided on one side of the lithium battery charging cabinet, a transmission mechanism is rotatably connected to the inner wall of the lithium battery charging cabinet, and a sealing plate is slidably provided on the inner wall of one side of the lithium battery charging cabinet;

[0009] A fire extinguishing seat is fixedly connected to one side of the lithium battery charging cabinet, and a nitrogen cylinder is installed in the lithium battery charging cabinet.

[0010] Preferably, a placement rack is fixedly provided inside the lithium battery charging cabinet, a charging cable is connected inside the lithium battery charging cabinet, a heat dissipation port is opened on one side of the lithium battery charging cabinet, a dustproof net is rotatably provided in the air inlet and the heat dissipation port of the lithium battery charging cabinet, and a smoke sensor is installed in the lithium battery charging cabinet.

[0011] Preferably, the heat-conducting mechanism includes an electric push rod, one end of which is connected and fixedly arranged inside the lithium battery charging cabinet, and the other end of the electric push rod is connected and fixedly arranged with a movable frame, a plurality of sliders are slidably arranged at the bottom of the movable frame, a spring is connected and fixedly arranged between the slider and the movable frame, a heat-conducting metal plate is connected and fixedly arranged on the slider, and the heat-conducting metal plate abuts against the outer wall of the lithium battery.

[0012] Preferably, the pushing mechanism includes a pushing plate, one side of the pushing plate is rotatably connected to two push rod groups, the other end of the push rod group is rotatably connected to the inner wall of the lithium battery charging cabinet, and one end of one of the push rod groups is fixedly connected to a motor.

[0013] Preferably, the transmission mechanism includes a worm, which is rotatably connected to the inner wall of the lithium battery charging cabinet, one end of the worm is fixedly connected to a gear via a universal joint A, one side of the push plate is fixedly connected to a rack, and the rack is meshed with the gear for transmission.

[0014] Preferably, a worm wheel is meshingly provided on one side of the worm gear, a universal joint B is fixedly connected to the worm wheel, the universal joint B is rotatably connected to the inner wall of the lithium battery charging cabinet, and the other end of the universal joint B is fixedly connected to a retractable rod.

[0015] Preferably, a slide groove is provided at the top of the sealing plate, and the inner wall of the slide groove is slidably matched with the other end of the retracting rod.

[0016] Preferably, the output end of the nitrogen bottle is connected to a ball valve, a valve stem is rotatably connected to the ball valve, a contact rod is fixedly connected to the outer end of the valve stem, a trigger rod is fixedly connected to the outer side of the push plate, and the trigger rod is in sliding contact with one end of the contact rod.

[0017] Preferably, a sealing cover is threadedly connected to one side of the fire extinguishing seat.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When charging lithium batteries in a lithium battery charging cabinet, multiple heat-conducting metal plates are used to contact the outer wall of the lithium battery. When contacting the surface of the lithium battery, the heat can be effectively transferred to the heat-conducting metal plates, thereby helping to quickly disperse the heat generated by the lithium battery to a larger surface during the charging process, thereby improving the overall heat dissipation efficiency;

[0020] When the lithium battery charging cabinet is charging the lithium battery, the smoke sensor is used to monitor the lithium battery fire in real time. When the lithium battery fire is detected, the lithium battery is automatically pushed into the fire extinguishing seat through the pushing mechanism, and the sealing plate seals the fire extinguishing seat, thereby automatically extinguishing the burning lithium battery;

[0021] When the burning lithium battery is pushed into the fire extinguisher seat, the ball valve will open, causing the high-pressure nitrogen in the nitrogen bottle to spray out, which can quickly dilute the oxygen in the flame to a level that is insufficient to sustain combustion, thereby extinguishing the fire. Nitrogen fire extinguishing can also reduce damage to equipment, further improving the fire extinguishing efficiency of the device and avoiding safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
