Example 1

Referring to fig. 1, a stake of silence heat dissipation formula new energy automobile charging, including fixing subaerial pile body 1 and burying underground seal box 11, install thermoelectric generation piece 3 on the pile body 1, fixed circulation pipeline 2 and the circuit module 9 of being provided with on the inner wall of pile body 1, the electro-magnet 6 is installed to circulation pipeline 2's interior roof department, circulation pipeline 2's lower extreme and seal box 11 are linked together, the symmetry is provided with two sliders 4 and two dog 5 in the circulation pipeline 2, and two sliders 4 all meet with circulation pipeline 2's the sealed slip of inner wall, and two dog 5 all meet with circulation pipeline 2's the sealed fixed of inner wall, circulation pipeline 2's upper portion symmetry intercommunication has two first connecting pipe 7, two first connecting pipe 7 are located between the slider 4 and the dog 5 that correspond the position, and first connecting pipe 7 is close to dog 5.

In this embodiment, the lower extreme symmetry of circulation pipeline 2 is around being equipped with two conductive coils 10, and two conductive coils 10 all are connected with circuit module 9 electricity, and thermoelectric generation piece 3 and electro-magnet 6 all are connected with circuit module 9 electricity, run through on the lateral wall of pile body 1 and are provided with second communicating pipe 8.

In this embodiment, the magnetic fluid is contained in the seal box 11, and the magnetic isolation sleeves are wrapped outside the circulation pipeline 2 and the seal box 11, so that the magnetic fluid is prevented from being influenced by a magnetic field except the electromagnet 6.

The present embodiment can illustrate the functional principle thereof by the following operation modes: when the charging pile works for a long time, the temperature inside the pile body 1 obviously rises, so that the cold end and the hot end of the thermoelectric generation piece 3 have obvious temperature difference, the voltage at the two ends of the thermoelectric generation piece 3 changes, corresponding current appears in a closed loop formed by the thermoelectric generation piece 3, the circuit module 9 and the electromagnet 6, the electromagnet 6 is electrified and generates a magnetic field in the vertical direction, wherein the circuit module 9 mainly plays roles of voltage stabilization, current stabilization and the like, and provides stable power output for the electromagnet 6;

because the circulation pipeline 2 and the outside of the seal box 11 are wrapped by the magnetic isolation sleeves, the magnetic fluid is only influenced by the magnetic field of the electromagnet 6, when the magnetic fluid is not in the magnetic field, the magnetic fluid is represented as stable colloidal liquid and does not show magnetism, and when the magnetic fluid is in the magnetic field, the magnetic fluid is immediately magnetized by the magnetic field and represents magnetism, so that after the electromagnet 6 is electrified, the magnetic fluid is magnetized and ascends upwards along the circulation pipeline 2 under the action of the magnetic field;

because the slide blocks 4 are in sealed sliding connection with the circulating pipeline 2, and the stop blocks 5 are in sealed fixed connection with the circulating pipeline 2, the magnetic fluid can push the two slide blocks 4 to move upwards, air between the slide blocks and the stop blocks 5 is extruded into the pile body 1 through the corresponding first communicating pipes 7, the air in the pile body 1 is disturbed, heat in a high-temperature area is taken away, and redundant air is discharged out of the pile body 1 through the second communicating pipes 8;

because the seal box 11 is buried underground, the temperature of the seal box 11 is relatively constant, so that the temperature of the magnetic fluid is far lower than the internal temperature of the pile body 1, when the magnetic fluid moves into the circulating pipeline 2, the circulating pipeline 2 can absorb the heat in the pile body 1, the effect similar to water cooling is achieved, and the silent heat dissipation effect is achieved;

when the magnetic fluid passes through the conductive coil 10 and is wound in the area, the magnetic field passing through the conductive coil 10 changes (the wound part of the conductive coil 10 is not provided with a magnetic isolation sleeve, and the conductive coil 10 is positioned at the lower part of the pile body 1 and is far away from the core area of the charging pile), according to the Faraday's law of electromagnetic induction, when the conductive coil 10 cuts a magnetic induction line, corresponding induced current can be generated in a closed loop, so that the conductive coil 10 can supply power to the circuit module 9, the circuit module 9 can store part of redundant electric energy, and when the temperature difference between two sides of the thermoelectric generation sheet 3 is reduced, the circuit module 9 can release the stored electric energy, so that the voltage at two ends of the electromagnet 6 is ensured to be constant, the retention time of the magnetic fluid in the circulating pipeline 2 is;

when the temperature in the pile body 1 is reduced to a normal range, no current is generated in a closed loop, a magnetic field excited by the electromagnet 6 disappears, the magnetic fluid falls back into the seal box 11 under the action of gravity, and under the action of gas pressure, the air part in the pile body 1 enters the circulating pipeline 2, so that the outside air enters the pile body 1 through the second communicating pipe 8, and the cooling effect is further improved.

Example 2

Referring to fig. 2 to 3, the present embodiment is different from embodiment 1 in that: be equipped with cooling air duct 14 and hold liquid box 15 in the seal box 11, hold and contain the clear water in the liquid box 15, it links to each other with water supply installation through buried pipe to hold liquid box 15, guarantee to hold and contain water in the liquid box 15 all the time, and cooling air duct 14 is located and holds liquid box 15 under, the middle part in cooling air duct 14 is comparatively narrow, cooling air duct 14 and hold and be equipped with a plurality of tubule passageways 16 of symmetry intercommunication between the liquid box 15, it still is equipped with a plurality of capillary 17 in the liquid box 15 to hold, and the lower extreme of every capillary 17 all extends to in the cooling air duct 14.

In this embodiment, an air supply pipe 12 and an air return pipe 13 are installed in the pile body 1, check valves are installed in both the air supply pipe 12 and the air return pipe 13, an air inlet pipe 18 and an air outlet pipe 19 are installed at both ends of the cooling air duct 14, the air supply pipe 12 is communicated with the air outlet pipe 19, and the air return pipe 13 is communicated with the air inlet pipe 18.

The present embodiment can illustrate the functional principle thereof by the following operation modes: the air in the pile body 1 enters the right end of the cooling air duct 14 through the air return duct 13 and the air inlet duct 18, then flows into the air outlet duct 19 and the air supply duct 12 from the left end of the cooling air duct 14 and then returns into the pile body 1, so that the circulation of the air in the pile body 1 is realized, and more high-temperature air is prevented from being gathered around a working part;

when the slide block 4 slides upwards to extrude the air in the circulating pipeline 2 into the pile body 1, the air in the pile body 1 is increased, the increased air enters the air return pipe 13 under the action of the one-way valve to start the circulation of the air, the middle part of the cooling air duct 14 is narrow, so that the air flow has a large flow speed when passing through the cooling air duct 14, the pressure intensity of a region with high flow speed is small according to Bernoulli principle, so that negative pressure can be generated in the cooling air duct 14, water in the liquid storage box 15 is sucked into the cooling air duct 14 through the thin pipe passage 16, the inner diameter of the thin pipe passage 16 is small, so that the water exists in the form of water mist after entering the cooling air duct 14, the contact area with the air flow is large, the temperature of the air flow can be quickly reduced, the temperature of the air flowing back into the pile body 1 is reduced, the cooling efficiency is improved, the air only circulates in the pile body 1, and the pile body 1 is not communicated with, thereby realizing dust-free heat exchange and ensuring the cleanness in the pile body 1;

it should be noted that the water mist taken away by the air flow through the cooling air duct 14 is very small, and the air flow needs to return to the interior of the pile body 1 through the air outlet pipe 19 and the air supply pipe 12, in this process, the water mist and the bent pipe collide with each other and then converge into larger water drops, the water drops are retained on the wall of the pipe under the action of tension, no adverse effect is generated on the working circuit of the pile body 1, when a plurality of water drops converge, water flow can be formed and flows back to the cooling air duct 14, and under the capillary effect of the capillary tube 17, the accumulated water in the cooling air duct 14 returns to the liquid storage box 15 to wait for the next cooling process.
