When the invention works, the temperature inside the box 10 is lower in cold weather environment, the air in the air bag 204 is not expanded, the air bag 204 can not push the inner plate 202 to slide downwards, the inner plate 202 presses the air bag under the elasticity of the spring II 205, at the moment, the fixed plate 2075 presses the inclined surface 2076 on the slide column 2072 to force the slide column 2072 to slide away from the vertical groove II 1051, the slide column 2072 can not block the stop lever 1053 to move upwards, the upper end of the sealing plate 105 is contacted with the top plate of the box 10 under the elasticity of the spring I106 to seal the exhaust window 103 at the upper end of the box 10, the exhaust channel of the air in the box 10 is blocked, so that the air in the box 10 can not flow, the heat generated during the operation of the electric component 30 can not be brought out of the box 10 through the flowing air flow, at the moment, the heat generated during the operation of the electric component 30 can prevent the temperature inside the box 10 from being too low, and further the performance of the electric component 30 such as a lithium battery for energy storage can be improved, and the electric component 30 can work stably.
When the temperature in the box 10 increases so that the gas in the hot gas bag 204 is heated, the gas bag expands to push the inner plate 202 to move downwards and push the sealing plate 105 to move downwards through the push rod 207, the exhaust window 103 is opened to form an air outlet channel, the higher the temperature in the box 10 is, the greater the expansion degree of the gas bag 204 is, the greater the downward moving distance of the inner plate 202 is, and the further the sealing plate 105 moves downwards, the greater the exhaust channel of the box is, the faster the gas flow in the box 10 is, and the faster the heat dissipation to the electric parts 30 is.
When the inner plate 202 moves downwards, the sliding column 2072 moves downwards to enable the inclined surface 2076 to leave the fixed plate 2075, the spring four 2073 forces the sliding column 2072 to slide and extend into the vertical groove two 1051, when the inner plate 202 moves downwards continuously, the sliding column 2072 pushes the stop lever 1053 downwards to enable the sealing plate 105 to move downwards until the air bag 204 is not expanded any more, the sealing plate 105 moves downwards to increase the opening degree of the air exhaust window 103 so as to improve the air convection speed in the box 10 to achieve the cooling effect, when the sealing plate 105 is in a stable state, when the temperature of one electric component 30 is increased relative to the temperature of the other electric component 30, the inner plate 202 corresponding to the high-temperature electric component 30 moves downwards continuously to enable the sealing plate 105 to move downwards, and when other sliding columns 2072 which extend into the vertical groove two 1051 but do not move downwards are encountered in the downward process of the sealing plate 105, the stop lever 1053 contacted with the other sliding columns 2072 which are overturned upwards to avoid the sliding column 2072 and are driven by the torsion spring to overturn to contact with the inner wall of the vertical groove two 1051. Therefore, the sliding of the inner plates 202 of one mounting plate 20 can not affect the sliding of the inner plates 202 of the other mounting plates 20, and all the inner plates 202 can independently drive the sealing plates 105 to slide, so that the average temperature in the box 10 is not needed to be considered to determine whether to drive the sealing plates 105 to slide, the temperature sensitivity is higher, and the reaction is faster.
In order to increase the emission rate of hot air at the exhaust window 103, the lower end of the waterproof board 111 is not set too low to ensure the ventilation rate at the exhaust window 103, when the temperature inside the box 10 is high to force the sealing board 105 to move downwards so that the upper end of the sealing board 105 is lower than the lower end of the waterproof board 111, if rain falls at this time, rainwater can easily float into the box 10 through the opened exhaust window 103, and in the invention, when the heat dissipation inside the box 10 needs to force the sealing board 105 to move downwards so that the upper end of the sealing board 105 is lower than the lower end cornice of the waterproof board 111, the pull rope 116 connected with the sealing board 105 pulls the inclined slide board 113 to slide upwards so as to enable the drainage channel 125 to penetrate, and the rainwater in the drainage channel 117 flows into the ponding cavity 121 of the rain baffle 12 along the water guide cloth 123 through the drainage channel 125 so that the weight of the rain baffle 12 is increased, and the rain baffle 12 is turned over vertically against the elasticity of the torsion spring to shield the opened exhaust window 103 in the horizontal direction so as to prevent rainwater from drifting into the box 10. The rain shield 12 which is forced to turn over to be in a vertical state reduces the total amount of the rain shield 105 when the water in the water accumulation cavity 121 is slowly discharged by the drainage micropores 124 after the rain is stopped, and then the rain shield 12 turns over upwards under the elasticity of the torsion springs on the rain shield 105 without shielding the exhaust window 103 so as to improve the ventilation rate at the exhaust window 103, accelerate the circulation rate of gas in the box 10 and further improve the cooling rate of the electrical part 30.
When the upper end position of the sealing plate 105 is higher than the lower end cornice of the waterproof plate 111, the pull rope 116 is in a loose state, the third spring 114 forces the inclined sliding plate 113 to slide so as to seal the drainage channel 125, so that rainwater cannot enter the water accumulation cavity 121 of the rain shielding plate 12, and at the moment, the torsion spring on the rain shielding plate 12 forces the rain shielding plate 12 to keep a horizontal state so as not to block the air exhaust window 103 and not to reduce the ventilation rate at the air exhaust window 103.
