[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0025] The present utility model provides a lead-acid battery with high specific energy as shown in Figures 1-5 and includes a battery housing 1. Heat dissipation control mechanisms 2 are provided on both sides of the battery housing 1. The heat dissipation control mechanism 2 includes a protective frame 201 fixedly connected to both sides of the battery housing 1. A dust filter screen 208 is fixedly connected to the inner side wall of the protective frame 201 to protect the internal structure of the protective frame 201. A plurality of groups of louvers 202 are rotatably connected to the inner side wall of the protective frame 201. A connecting rod 203 is fixedly connected between the multiple groups of louvers 202. A steel wire is fixedly connected between the multiple groups of connecting rods 203. A trigger rod 204 is fixedly connected to the outer side wall of the connecting rod 203 and the trigger rod 204 is slidably connected to the inner side wall of the protective frame 201. A piston 206 is fixedly connected to the bottom end of the trigger rod 204. The piston 206 is slidably connected to the inside of the liquid storage tube 205. An expansion liquid 207 is provided inside the liquid storage tube 205. The characteristics of thermal expansion and contraction of the expansion liquid 207 are used to provide power. The connecting part of the trigger rod 204 and the piston 206 is in the shape of a thin rod and the diameter of the thin rod is smaller than the diameter of the top of the trigger rod 204 to increase the pressure and enhance the thrust. The upper half of the liquid storage tube 205 has a smaller diameter than its lower half. The connecting rod 203 penetrates through the top of the trigger rod 204 to cooperate with the piston 206 to increase the pressure to ensure the stability of the structure. Through the cooperation of the battery housing 1 and the heat dissipation control mechanism 2, when the temperature inside the battery housing 1 changes, the expansion liquid 207 inside the liquid storage tube 205 rises and falls according to the temperature, thereby driving the piston 206 and the trigger rod 204 to rise and fall inside the liquid storage tube 205, and using the shapes of the liquid storage tube 205 and the piston 206 to increase the pressure, and then driving the shape of the louvers 202 to change, so as to assist heat dissipation or hinder heat dissipation, in order to improve the service life and stability of the structure.

[0026] Refer to the attached instructions Figures 1-5, a high-energy battery 9 is fixedly connected to the bottom wall of the battery case 1. Anti-collision columns 6 are fixedly connected to the four corners of the battery case 1 to further protect the high-energy battery 9 and the battery case 1. A battery cover 3 is arranged on the top of the battery case 1. A plurality of groups of air vents 5 are formed on the surface of the battery cover 3. A fixing bolt 4 is threadedly connected to the top end of the battery cover 3, and the bottom end of the fixing bolt 4 is threadedly connected to the top end of the battery case 1. The connection between the battery case 1 and the battery cover 3 is realized through the fixing bolt 4, and the high-energy battery 9 is assisted in heat dissipation by using the air vents 5. A plurality of groups of heat conduction blocks 8 are fixedly connected to both sides of the battery case 1. One end of the heat conduction block 8 is fixedly connected to a heat sink 7. The end of the heat sink 7 away from the heat conduction block 8 is located inside the protection frame 201. The heat is conducted to the heat sink 7 by using the heat conduction block 8, and heat exchange is carried out with the outside through the heat sink 7, thereby improving the heat dissipation efficiency. Two groups of support frames 10 are fixedly connected to the bottom end of the battery case 1. Two fixing holes 11 are formed on the surface of the support frame 10 to protect the battery case 1 and provide support and connection functions for it.

[0027] The working principle of this utility model:

[0028] Refer to the attached Figures 1-5 , when the battery case 1 is working, the heat is conducted to the heat sink 7 by using the heat conduction block 8, and heat exchange is carried out with the outside through the heat sink 7. The expansion liquid 207 inside the liquid storage tube 205 expands and contracts according to the temperature to realize the rise and fall of the liquid level of the expansion liquid 207, thereby driving the piston 206 and the trigger rod 204 to rise and fall inside the liquid storage tube 205, and using the shapes of the liquid storage tube 205 and the piston 206 to increase the pressure, and then driving the activities of the connecting rod 203 and the louvers 202, so that the shape of the louvers 202 is changed, thereby assisting heat dissipation or hindering heat dissipation to change the contact amount between the heat sink 7 and the outside air. When the external temperature is relatively low, the liquid level of the expansion liquid 207 drops, driving the trigger rod 204 and the connecting rod 203 to drop, so that the louvers 202 are relatively closed, reducing the heat exchange efficiency between the heat sink 7 and the outside air, thereby facilitating the heating of the high-energy battery 9, and vice versa, thereby improving the service life and stability of this structure.
