[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0014] Depend on Figures 1 to 5 This utility model discloses a lithium battery aluminum profile shell for a solar street light, comprising an aluminum profile shell body 1, which is composed of a main shell 2, a lithium battery heat dissipation jacket 3, and a bottom cover plate 4. The main shell 2 is installed at the bottom of the solar panel bracket by several bolts. The lithium battery heat dissipation jacket 3 is installed inside the main shell 2 by several bolts, and the lithium battery is installed inside the lithium battery heat dissipation jacket 3. The bottom cover plate 4 is installed at the bottom end of the main shell 2 by several bolts. A hollow interlayer 5 is provided inside the main shell 2, and the hollow interlayer 5 is filled with heat insulation cotton 6. The lithium battery heat dissipation jacket 3 is composed of a copper limiting sleeve 7 and several copper heat-conducting plates 8. The copper heat-conducting plates 8 are welded to the bottom end of the copper limiting sleeve 7. An aluminum heat dissipation jacket 9 is provided through the bottom end of the bottom cover plate 4 and welded to the bottom cover plate 4. The copper heat-conducting plates 8 are inserted inside the aluminum heat dissipation jacket 9, and thermal conductive silicone grease is filled between the copper heat-conducting plates 8 and the aluminum heat dissipation jacket 9. The lithium battery heat dissipation jacket 3 secures and installs the lithium battery, improving its stability and placing it at the top of the main housing 2 to prevent rain damage. The hollow interlayer 5 and insulation cotton 6 enhance the insulation performance of the main housing 2. The copper limiting sleeve 7, copper heat-conducting plate 8, and aluminum heat dissipation jacket 9 improve the heat dissipation performance of the lithium battery. Heat from the lithium battery is transferred to the copper limiting sleeve 7, then to the copper heat-conducting plate 8, and finally to the aluminum heat dissipation jacket 9. Thermal grease enhances the thermal conductivity of the copper heat-conducting plate 8 and the aluminum heat dissipation jacket 9, achieving efficient heat dissipation through the aluminum heat dissipation jacket 9. This prevents the lithium battery from overheating and affecting its lifespan. In low-temperature winter conditions, the aluminum heat dissipation jacket 9 has lower thermal conductivity than the copper limiting sleeve 7 and the copper heat-conducting plate 8, thus reducing the reverse transfer of low temperatures. Bolt mounting brackets 10 are fixedly installed at the top of both ends of the main housing 2, which can install the main housing 2 with the solar panel bracket. A rubber pad 11 is installed on the top surface of the main housing 2 to provide a cushioning effect. An L-shaped conduit 12 is provided through one end of the main housing 2, and a wire groove 13 matching the L-shaped conduit 12 is opened on the top of one end of the copper limiting sleeve 7, so that the cable can pass through. Several bolt mounting supports 14 are fixedly installed on the top of both ends of the copper limiting sleeve 7, which can stably connect the copper limiting sleeve 7 to the main housing 2. Several strip-shaped through grooves 15 are opened on both sides of the copper limiting sleeve 7, which can improve the heat exchange effect between the lithium battery and the inner cavity of the main housing 2. The top of the bottom cover plate 4 is welded with a rectangular positioning frame 16 that matches the main housing 2, which can realize the installation positioning function and also has a waterproof effect. The side of the top of the main housing 2 is provided with a sealing gasket 17, which can improve the waterproof performance of the connection. The bottom cover plate 4 has several through holes 18 on the side of the top end, and several bolt mounting grooves 19 communicating with the through holes 18 on the side of the bottom end, so that the bottom cover plate 4 can be connected to the main housing 2 by bolts.
[0015] In operation, by setting up an aluminum profile outer shell consisting of a main casing, a lithium battery heat dissipation jacket, and a bottom cover plate, and installing the main casing at the bottom of the solar panel bracket, and fixing the bottom cover plate to the bottom of the main casing with several bolts, rainwater can be prevented from entering the lithium battery, thus improving the waterproof effect. By setting a hollow interlayer inside the main casing and filling the hollow interlayer with heat insulation cotton, the heat insulation effect of the main casing can be improved, preventing the internal temperature of the main casing from being too low during winter use, which would affect the energy storage of the lithium battery. By setting up a lithium battery heat dissipation jacket consisting of a copper limiting sleeve and several copper heat-conducting plates, and setting up an aluminum heat dissipation sleeve, heat dissipation of the lithium battery can be facilitated, preventing the temperature from being too high during summer use, which would affect the lifespan of the lithium battery.
