[0002] For electric vehicle charging, special charging piles and charging places are needed, which have large floor area and limited quantity, and it is difficult to meet the charging demand of more and more electric vehicles, so how to effectively increase the number of charging piles in city becomes one of the research directions.Wisdom street lamp is based on road lighting pole, integrates traffic signal, communication, traffic signboard and so on, realizes multi-pole integration, reduces road vertical pole, and releases public space resource.At the same time, as an important carrier of wisdom city construction, wisdom street lamp will be the port of internet of things, and play a greater "complex" role.

[0003] The existing wisdom street lamp is welded with energy storage battery and automobile charging pile module on lamp pole, and can be connected with mains or photovoltaic power generation system, to achieve the effect of power storage and charging integration, provide charging service for new energy vehicles, and improve the convenience of equipment.

[0004] The prior art in the above has the following defects: the power of new energy vehicle charging is large, a large amount of heat is generated during battery charging and discharging, the battery is overheated, and even the battery is burned out in serious cases, which greatly affects the safe use of equipment. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a liquid cooling battery module for storage and charging integrated wisdom street lamp.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] The light pole includes several functional modules mounted on its outer wall. A component compartment is fixedly mounted at the bottom of the light pole, comprising an upper device compartment and a lower energy storage compartment. A battery slot is formed on the outer wall of the energy storage compartment. A heat spreader block is fixedly mounted against the wall of the battery slot. Several parallel blade batteries are slidably fitted onto the side of the heat spreader block near the slot opening. Protective cover plates, fitted into the battery slots, are connected to the ends of the blade batteries away from the heat spreader block. A locking screw threaded through the protective cover plate and connected to the heat spreader block is also provided. The heat exchange block has a flow channel inside that encloses the blade battery. The flow channel is S-shaped and folds back and forth, passing through the intervals of the blade battery. A flow pipe is installed through the side of the energy storage compartment away from the battery compartment, connecting the two ends of the flow channel. The flow pipe and the flow channel are filled with sufficient coolant. A circulation pump that drives the coolant circulation is fixedly installed on the outer wall of the energy storage compartment. Several heat dissipation fins are fixedly installed on the outer wall of the energy storage compartment. The flow pipe passes through the heat dissipation fins. Several cooling fans are fully installed on the side of the heat dissipation fins away from the energy storage compartment.

[0008] By adopting the above technical solution, the heat spreader is made of a high thermal conductivity material. Sufficient space is left between the parallel blade batteries, effectively increasing the contact area between the blade batteries and the heat spreader compared to traditional single large batteries. This facilitates the rapid transfer of heat from the blade batteries to the heat spreader. The space also allows for the flow channels to pass around each blade battery. While increasing the contact area between the flow channels and the heat spreader, it also allows for multi-angle wrapping of the blade batteries, achieving uniform and efficient heat conduction. The heat in the heat spreader is absorbed by the coolant. Under the pumping of the circulating pump, the heat is dispersed onto the heat dissipation fins through the flow channels. Finally, the cooling fan drives the airflow around the heat dissipation fins to release the heat into the external environment. After the coolant temperature decreases, it is recycled. This process stably and efficiently transfers the heat from the blade batteries layer by layer to the surrounding environment, effectively reducing the operating temperature of the blade batteries and preventing heat buildup inside the energy storage compartment that could damage the batteries.

[0009] Furthermore, the heat exchange block has a fitting groove for the blade battery to be fitted and placed, and one end of the blade battery inserted into the heat exchange block is fixedly provided with a power-conducting interface. The groove wall of the fitting groove has a power-conducting groove that matches the power-conducting interface.

[0010] By adopting the above technical solution, the power interface, together with the power slot, can automatically connect the battery to the device's circuit after inserting the blade battery, achieving a plug-and-play effect and greatly increasing convenience.

[0011] Furthermore, a buckle is fixedly provided at one end of the blade battery near the protective cover, and a locking groove is provided on the outer wall of the protective cover to prevent the blade battery from locking, and the locking groove is provided with a slot for cooperating with the buckle.

[0012] By adopting the above technical solution, the blade battery and the protective cover are installed by snap-fit. When the total battery capacity needs to be large, the number of blade batteries inserted into the protective cover can be increased, and vice versa, so as to achieve the effect of selecting the installed capacity of the blade battery according to actual needs.

[0013] Furthermore, a push-pull handle is fixedly provided on the outer wall of the protective cover, a sealing rubber ring is provided around the periphery of the protective cover, and a sealing groove is provided in the battery slot for the sealing rubber ring to fit into.

[0014] By adopting the above technical solution, the push-pull handle makes it easy for users to apply force to switch the protective cover. The sealing rubber ring, together with the sealing groove, effectively fills the joint between the sealing cover and the battery compartment, preventing external impurities and foreign objects from entering through this gap and affecting the normal operation of the battery.

[0015] Furthermore, the guide tube is arranged in a U-shape and passes through the heat dissipation fins multiple times, and the outer wall of the energy storage chamber is covered with a perforated protective cover that covers the heat dissipation fins and the cooling fan.

[0016] By adopting the above technical solution, the guide tube is folded in a U-shape and passes through the heat dissipation fins multiple times, which can effectively increase the contact area between the guide tube and the heat dissipation fins, further improving the heat dissipation capacity of the equipment. The multi-hole protective cover has a good protective effect, which does not affect the stable airflow of the cooling fan for heat dissipation, while preventing the heat dissipation fins and cooling fan from being damaged by the outside world.

[0017] Furthermore, the functional module includes a lighting module that provides lighting, a foldable photovoltaic panel, a multimedia box that displays information, and a control box that controls the system. The lighting module, photovoltaic panel, energy storage battery, and multimedia box are electrically connected to the control box. A control panel is embedded in the outer wall of the control box, and a charging gun is electrically connected to the outer wall of the control box. An LCD screen and a speaker are embedded in the outer wall of the multimedia box.

[0018] By adopting the above technical solutions, the lighting module, energy storage battery, and photovoltaic panel, under the control of the control box, provide sufficient lighting at night and store excess power in the blade battery. The charging gun facilitates the new energy vehicle to draw power from the blade battery to maximize energy utilization. The multimedia box has a good information display function and can play various information under the control of the control box, improving the convenience of the equipment.

[0019] In summary, the beneficial technical effects of this utility model are as follows:

[0020] 1. It adopts heat dissipation blocks, flow channels, flow pipes, circulation pumps, heat dissipation fins and cooling fans, so as to stably and efficiently transfer the heat in the blade battery to the surrounding environment, effectively reduce the operating temperature of the blade battery and avoid the battery damage caused by heat accumulation inside the energy storage compartment.

The component compartment 2 includes an upper device compartment 3 and a lower energy storage compartment 4. A battery slot 41 is formed on the outer wall of the energy storage compartment 41. A heat spreader 5 is fixedly installed against the wall of the battery slot 41. Several parallel blade batteries 6 are slidably fitted onto the side of the heat spreader 5 near the slot opening. Protective cover plates 7, fitted into the battery slot 41, are connected to the ends of the blade batteries 6 away from the heat spreader 5. Threaded connections are provided through the protective cover plates 7. The heat spreader 5 is secured by locking bolts 71. Inside the heat spreader 5, there is a guide channel 51 that encloses the blade battery 6. The guide channel 51 is S-shaped and folds back and forth, passing through the intervals of the blade batteries 6. A guide pipe 52, connecting both ends of the guide channel 51, is installed through the side of the energy storage chamber 4 away from the battery slot 41. The guide pipe 52 and the guide channel 51 are filled with sufficient coolant. A circulation pump 53, driving the coolant circulation, is fixedly installed on the outer wall of the energy storage chamber 4. Several heat dissipation fins 54 are fixedly installed on the outer wall of the energy storage chamber 4, and the guide pipe 52 passes through the heat dissipation fins 54. The side of the heat sink fins 54 furthest from the energy storage compartment 4 is fully covered with several cooling fans 55. The heat spreader 5 is made of a high thermal conductivity material, and the blade batteries 6 are arranged parallel to each other with sufficient space between them. The contact area between the blade battery 6 and the heat spreader 5 is effectively increased compared to a traditional single large battery, which facilitates the rapid transfer of heat from the blade battery 6 to the heat spreader 5. The space between them also facilitates the flow guide channel 51 to pass around and pass through each blade battery 6. While increasing the contact area between the flow guide channel 51 and the heat spreader 5, it can also wrap around the blade battery 6 at multiple angles. To achieve uniform and efficient heat conduction, the heat in the heat exchange block 5 is absorbed by the coolant. Under the pumping of the circulating pump 53, the heat is distributed to the heat exchange fins 54 through the guide pipe 52. Finally, the heat is released to the external environment by the airflow around the heat exchange fins 54 driven by the cooling fan 55. After the coolant temperature drops, it is recycled. The heat in the blade battery 6 is stably and efficiently transferred to the surrounding environment layer by layer, which can effectively reduce the operating temperature of the blade battery 6 and prevent the battery from being damaged by heat accumulation inside the energy storage compartment 4.

[0036] The heat spreader block 5 has a fitting groove 56 for the blade battery 6 to be fitted and placed. One end of the blade battery 6 inserted into the heat spreader block 5 is fixedly provided with a power interface 61. The groove wall of the fitting groove 56 has a power groove that matches the power interface 61. The power interface 61 matches the power groove, so that after the blade battery 6 is inserted, the battery can be automatically connected to the circuit of the device, achieving a plug-and-play effect and greatly increasing the convenience.

[0037] A buckle 62 is fixedly installed at one end of the blade battery 6 near the protective cover 7. The outer wall of the protective cover 7 has a locking groove 63 for locking the blade battery 6. The locking groove 63 has a slot 64 that matches the buckle 62. The blade battery 6 and the protective cover 7 are locked together by the buckle 62. When the total battery capacity needs to be large, the number of blade batteries 6 inserted on the protective cover 7 can be increased, and vice versa, so as to achieve the effect of selecting the installed capacity of the blade battery 6 according to the actual needs.

[0038] A push-pull handle 72 is fixedly installed on the outer wall of the protective cover 7, and a sealing rubber ring 73 is arranged around the periphery of the protective cover 7. The battery compartment 41 has a sealing groove 74 for the sealing rubber ring 73 to fit into. The push-pull handle 72 makes it easy for the user to open and close the protective cover 7. The sealing rubber ring 73, together with the sealing groove 74, effectively fills the joint between the sealing cover and the battery compartment 41, preventing external impurities and foreign objects from entering through this gap and affecting the normal operation of the battery.

[0039] The guide pipe 52 is arranged in a U-shape and passes through the heat dissipation fins 54 multiple times. The outer wall of the energy storage chamber 4 is covered with a perforated protective cover 8 covering the heat dissipation fins 54 and the cooling fan 55. The U-shaped fold of the guide pipe 52 passing through the heat dissipation fins 54 multiple times can effectively increase the contact area between the guide pipe 52 and the heat dissipation fins 54, further improving the heat dissipation capacity of the equipment.
