DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figure 1-Figure 5 The present application provides a protective shell, including a shell 1 and a bottom plate 2.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The housing 1 is sealed and arranged on the bottom plate 2. The housing 1 is provided with a heat dissipation port and an air inlet. A heat dissipation element 3 is arranged inside the heat dissipation port. A filter screen 4 is arranged inside the air inlet. A placement box 5 is installed directly below the filter screen 4. Specifically, the top side of the placement box 5 is also connected to the top wall inside the housing 1 to increase the stability of the placement box 5. A desiccant 8 is placed inside the placement box 5. A fixing frame 7 is fixedly connected to the inner side of the heat dissipation element 3 and located inside the housing 1. A wind induction plate 6 is connected to one side of the placement box 5. The wind induction plate 6 is connected to one side of the fixing frame 7. Among them, the high-energy-density high-safety solid-state power source body 9 is first installed on the base plate 2, and then the shell 1 is connected to the base plate 2. When the high-energy-density high-safety solid-state power source body 9 is in operation, the heat dissipation fan installed thereon will operate to dissipate heat for it. When the heat dissipation fan dissipates heat, the hot air will gather inside the fixed frame 7, and then the heat dissipation member 3 will extract the heat inside the fixed frame 7 to dissipate heat. When the external wind is filtered through the filter screen 4 on the air inlet and enters the placement box 5, the moist air entering is dried by the desiccant 8, and the dried wind enters the fixed frame 7 through the air duct plate 6 to realize the gas exchange of the heat dissipation fan. Through the arrangement of the placement box 5, the air duct plate 6, the fixed frame 7 and the desiccant 8, when the high-energy-density high-safety solid-state power source body 9 is dissipated, the gas exchange will also prevent the moist air from entering the shell 1, thereby improving the moisture-proof effect of the entire shell 1, so as to ensure the normal use of the high-energy-density high-safety solid-state power source body 9 and increase the service life.

[0026] In this embodiment, the heat sink 3 includes a heat conducting plate 31 and heat dissipation fins 32. The heat conducting plate 31 is installed inside the heat dissipation port, and the bottom of the heat conducting plate 31 is fixedly connected to the fixing frame 7. Each heat dissipation fin 32 is equidistantly installed on the heat conducting plate 31. The hot air inside the fixing frame 7 is transferred to the heat dissipation fins 32 through the heat conducting plate 31, and the heat dissipation fins 32 dissipate the heat into the air.

[0027] In the specific configuration, the bottom of the housing 1 is fixedly connected with an ear plate 11, and the ear plate 11 is sealed and connected with the bottom plate 2. A sealing gasket 12 is adhered to the lower surface of the ear plate 11, and the sealing gasket 12 is in contact with the bottom plate 2. Connecting bolts are provided on the ear plate 11 and the bottom plate 2. The connecting bolts allow the housing 1 and the bottom plate 2 to be disassembled, which facilitates the disassembly and maintenance of the housing 1, and the sealing gasket 12 can seal the ear plate 11 and the bottom plate 2.

[0028] In this embodiment, a threading hole is provided on one side of the housing 1, and an elastic sealing ring is provided inside the threading hole. The threading hole facilitates the insertion of the power cord, and the elastic sealing ring can fit tightly with the power cord.

[0029] See also Figure 1-Figure 5 The embodiment of the present application further provides a high specific energy and high safety solid-state power supply, including a protective shell and a high specific energy and high safety solid-state power supply body 9.

[0030] The high specific energy and high safety solid-state power supply body 9 is arranged inside the shell 1, and a cooling fan is installed on the high specific energy and high safety solid-state power supply body 9. The bottom of the fixed frame 7 contacts the top wall of the high specific energy and high safety solid-state power supply body 9, and the air outlet of the cooling fan is located inside the fixed frame 7.

[0031] The working principle of the protective shell and the high-energy-density high-safety solid-state power supply is as follows: first, the high-energy-density high-safety solid-state power supply body 9 is installed on the bottom plate 2, and then the shell 1 is connected to the bottom plate 2. When the high-energy-density high-safety solid-state power supply body 9 is in operation, the heat dissipation fan installed thereon will operate to dissipate heat for it. When the heat dissipation fan dissipates heat, the hot air will gather inside the fixed frame 7, and then the heat dissipation member 3 will extract the heat inside the fixed frame 7 to dissipate heat. When the external wind is filtered through the filter screen 4 on the air inlet and enters the placement box 5, the moist air entering is dried by the desiccant 8, and the dried wind enters the fixed frame 7 through the air inlet plate 6 to realize the gas exchange of the heat dissipation fan. By setting the placement box 5, the air inlet plate 6, the fixed frame 7 and the desiccant 8, the gas exchange when the high-energy-density high-safety solid-state power supply body 9 is dissipated will also prevent the moist air from entering the shell 1, thereby improving the moisture-proof effect of the entire shell 1, so as to ensure the normal use of the high-energy-density high-safety solid-state power supply body 9 and increase the service life.
