By adopting the technical scheme, in the process that the second elastic air bag 10 extrudes the first elastic air bag 9, the gas in the groove 22 is discharged, and the space between the groove 22 and the outer wall of the first elastic air bag 9 is in a negative pressure state, so that the first elastic air bag 9 and the second elastic air bag 10 are tightly adsorbed together, and therefore, when the temperature in the second elastic air bag 10 is reduced, the second elastic air bag 10 can be prevented from being slowly restored, and only when the groove 22 and the first elastic air bag 9 are separated from contact, the second elastic air bag 10 can be restored, namely, the second elastic air bag 10 is suddenly changed, so that the shaking amplitude of the second elastic air bag 10 for driving the fluorinated liquid 5 is increased.
As shown in fig. 4, the edge of the spoiler 20 is a cambered surface.
Through adopting above-mentioned technical scheme, because spoiler 20 and elastic rope 19 contact to the spoiler 20 presss from both sides the position between first magnet 11 and second magnet 12, and the edge of spoiler 20 is easy to contact with elastic rope 19 this moment, consequently can reduce the frictional force that elastic rope 19 received through setting up the spoiler 20 edge to the cambered surface, played the effect of protection elastic rope 19.
The using method comprises the following steps: during normal operation, the probe generates heat, which is emitted to the outside through the heat conductive sheet 4 and part of the heat is absorbed by the ammonia gas in the second elastic balloon 10, the ammonia gas expands and the second elastic balloon 10 expands; when the heat in the shell 1 cannot be timely emitted to the outside due to excessive heat, ammonia gas rapidly expands, at the moment, the second magnet 12 has a trend of being far away from the first magnet 11, when the thrust of the ammonia gas in an expanded state to the bottom wall of the second elastic air bag 10 is larger than the attractive force between the first magnet 11 and the second magnet 12, the first magnet 11 is separated from the second magnet 12, at the moment, the second elastic air bag 10 rapidly expands and presses the first elastic air bag 9, because the diameter of the output end of the first elastic air bag 9 is larger than that of the input end of the first elastic air bag 9, the fluorinated liquid 5 in the first elastic air bag 9 is pressed and discharged through the output end of the first elastic air bag 9, at the moment, the fluorinated liquid 5 discharged in the first elastic air bag 9 is discharged through the through hole 8, at the moment, the fluorinated liquid 5 discharged in the through hole 8 impacts the bottom wall of the heat conducting sheet 4, at the moment, the heat conducting sheet 4 moves towards the direction far away from the through hole 8, the heat conducting sheet 4 in a moving state drives air around the shell 1 to shake, and the probability that low-temperature gas around the shell 1 contacts the shell 1 is increased; at the moment that the first magnet 11 and the second magnet 12 are separated from each other, the second elastic air bag 10 is suddenly deformed, and the inflated second elastic air bag 10 drives the fluorinated liquid 5 in the shell 1 to shake, so that the contact probability of the liquid fluorinated liquid 5 and the detection head 2 is increased, and the cooling effect on the detection head 2 is improved; and in the process that the fluorinated liquid 5 sprayed out of the through hole 8 is contacted with the heat conducting fin 4, the temperature of the part of fluorinated liquid 5 is reduced, and when the part of fluorinated liquid 5 with low temperature falls on the surface of the detection head 2, the cooling effect on the detection head 2 is further improved.
When the elastic membrane 7 is deformed, the cavity 15 is extruded and the volume of the cavity 15 is reduced, so that the gas in the cavity 15 flows into the cavity 13 and finally is discharged through the air hole 14, at the moment, the gas discharged from the air hole 14 impacts the air with higher temperature on the surface of the shell 1 and impacts the part of the air with higher temperature into the space far away from the shell 1, the air flow rate on the surface of the shell 1 is further increased, the cooling effect on the shell 1 is improved, when the liquid discharged from the through hole 8 impacts the inclined surface of the baffle 16, the baffle 16 moves towards the direction far away from the through hole 8, and under the action of inertia, the baffle 16 drives the heat conducting fin 4 to move rapidly and the baffle 16 is separated from contact with the liquid column discharged from the through hole 8; when the heat conducting strip 4 is furthest far away from the through hole 8, the elastic membrane 7 is restored and drives the stop block 16 to contact with liquid sprayed from the through hole 8 again, so that the stop block 16 can drive the heat conducting strip 4 to shake back and forth, the air flow rate around the shell 1 is increased, and the cooling effect on the periphery of the shell 1 is improved; when the first magnet 11 and the second magnet 12 are separated from contact, the elastic rope 19 is stretched, the spoiler 20 shakes back and forth under the action of inertia, and the gas in the second elastic air bag 10 can be driven to shake in the shaking process of the spoiler 20, so that the contact probability of the high-temperature gas in the second elastic air bag 10 and the end face of the heat conducting rod 18 is increased, the temperature in the second elastic air bag 10 can be timely reduced, namely, the second elastic air bag 10 can be quickly restored, and the shaking amplitude of the fluorinated liquid 5 in the shell 1 is increased.
