Referring to the attached Fig. 1-4, a plurality of spiral curved pipes 51 are arranged on the inner side of the cooling cavity 43, and the corresponding spiral curved pipes 51 are connected with the air inlet 5. Each spiral curved pipe 51 is internally provided with drying particles 54, and the other end of each spiral curved pipe 51 is connected with an air inlet 55 extending into the protective casing 1, through which the outside air enters the spiral curved pipes 51. Due to the special design of the spiral curved pipe 51, the residence time of the air in the spiral curved pipe 51 can be increased, so that the air can be fully cooled, and the high temperature of the outside air can be avoided, which will affect the heat dissipation efficiency. Then, the air enters the inside of the protective casing 1 through the air inlet pipe 55, and when it passes through the spiral curved pipe 51, the air will contact with the dry particles 54 to absorb the moisture in the air, thus avoiding the damage of the battery pack 2 caused by the high humidity of the outside air.
Referring to the attached Fig. 1, 2, 5 and 7. Both sides of the protective hull 1 are connected with integrated expansion parts 6. Two expansion parts 6 are internally provided with rotating screws 61. The rotating screws 61 are threaded with a moving ring 62, and the moving ring 62 is provided with an exhaust fan 69. The side wall of the expansion part 6 is provided with an exhaust port 63, and a filter screen 12 is installed inside the exhaust port 63. The filter screen 12 can prevent the exhaust fan 69 from stopping running. The foreign matter enters into the protective casing 1 from the exhaukt502358 port 63, and a telescopic hose 64 is connected between the exhaust fan 69 and the exhaust port 63. A driving wheel 65 and a motor 66 are installed on one side of the protective hull 1, and the output end of the motor 66 is connected with the axis of the driving wheel 65. Two driven wheels 67 are arranged on both sides of the driving wheel 65, and a chain belt 68 is connected between the two driven wheels 67 and the driving wheel 65, and the two driven wheels 67 and the two rotating screws 61 are in one-to-one correspondence and connected with the axis. The motor 66 is started to rotate the driving wheel 65, and the two driven wheels 67 are rotated by the chain belt 68, so that the two rotating screws 61 rotate, the moving ring 62 is driven to move, and the exhaust fan 69 is started, so that the exhaust fan 69 can completely exhaust the internal hot air, avoiding only partial air discharge, and only one exhaust port 63 is adopted. A telescopic hose 64 is connected between the exhaust port 63 and the exhaust fan 69, which can avoid the trouble of foreign matters entering from the exhaust port 63 on the premise of ensuring effective heat dissipation.
The specific operation flow of the invention is as follows: The battery pack 2 is placed in the protective hull 1, the shock-absorbing seat block 11 supports the battery pack 2, then each moving screw 31 is rotated to move the mounting right-angled plate 32 until the rubber right-angled plate 33 contacts the battery pack 2, the battery pack 2 is preliminarily fixed, then the protective hull cover 4 is covered, and the telescopic rod 41 is positioned to abut on the upper end face of the battery pack 2. Because of that existence of the extension spring 42, the battery pack 2 is fixed, the positioning components 3 can be adaptively adjusted, according to the size of the battery pack 2, which can be applied to most battery pack 2, thus having strong practicability, the heat-conducting copper sheet 44 absorbs the heat generated by the battery pack 2 and transmits it to the cooling cavity 43, and the cooling liquid in the cooling cavity 43 absorbs the heat and evaporates into steam and enters the cooling box 45, through the heat dissipation of the heat-dissipating aluminum plate 46, the steam heat is dissipated, and the cooling liquid that has lost heat is liquefied and dripped down, and returns to the cooling cavity 43 again, so that the whole process of circulating water cooling is realized, and the heat dissipation efficiency of the battery pack 2 is increasefU502358 The outside air enters into the air inlet 5, and first, it is preliminarily filtered by the filter screen 12 to isolate most impurities in the air, thus avoiding pipeline blockage, and the air keeps moving forward. Because the baffles 52 are staggered up and down, and there are no straight air passages in several baffles 52.
The viscose cardboard 56 can absorb the impurities in the air, thus ensuring the purity of the air and preventing the impurities from affecting the battery pack 2. The outside air enters the spiral curved pipe 51 through the air inlet 5. Due to the special design of the spiral curved pipe 51, the residence time of the air in the spiral curved pipe 51 can be increased, so that the air can be sufficiently cooled, and the high temperature of the outside air can be prevented from affecting the heat dissipation efficiency. Then, the air enters the protective casing 1 through the air inlet 55. When the air passes through the spiral curved pipe 51, it will contact with the dry particles 54 to absorb the moisture in the air, so as to avoid the damage of the battery pack 2 caused by the high humidity of the outside air. The motor 66 is started to rotate the driving wheel 65, and the two driven wheels 67 are rotated by the chain belt 68, so that the two rotating screws 61 rotate, the moving ring 62 is driven to move, and the exhaust fan 69 is started, so that the exhaust fan 69 can completely exhaust the internal hot air, avoiding only partial air exhaust, and only one exhaust port 63 is adopted, and a telescopic hose 64 is connected between the exhaust port 63 and the exhaust fan 69. On the premise of ensuring effective heat dissipation, the trouble of foreign matters entering from the exhaust port 63 is avoided.
The invention has been described by way of example with reference to the above drawings. Obviously, the specific implementation of the invention is not limited by the above way. As long as the immaterial improvement of the method concept and technical scheme of the invention is adopted, or the idea and technical scheme of the invention are directly applied to other occasions without improvement, it is within the scope of protection of the invention.
