[0049] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] A cooling device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0051] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the cooling device includes a pusher 1 and a magnetic drive assembly 2. The magnetic drive assembly 2 is connected to the pusher 1 and is used to drive the pusher 1 to move. The pusher 1 is adapted to be installed in the cooling channel. When the pusher 1 moves, it can push the cooling medium to flow in the cooling channel.

[0052] Specifically, the magnetic drive assembly 2 is connected to a wire terminal 221, which is connected to the PCB board 8 via wires. The PCB board 8 sends an electrical signal to the magnetic drive assembly 2, thereby energizing the magnetic drive assembly 2. When energized, the magnetic drive assembly 2 can drive the pusher 1 to move, thereby pushing the cooling medium to flow in the cooling channel.

[0053] In some other embodiments, both the magnetic drive assembly 2 and the pusher 1 can be disposed within the cooling channel, as long as the pusher 1 can push the cooling medium to flow within the cooling channel.

[0054] According to some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9 As shown, the magnetic drive assembly 2 includes a first moving iron core 21 and a first electromagnetic coil 22. The first moving iron core 21 is connected to the pusher 1. The first moving iron core 21 is placed inside the first electromagnetic coil 22. When the first electromagnetic coil 22 is energized, the first moving iron core 21 is driven, thereby driving the pusher 1 to move.

[0055] Specifically, the first electromagnetic coil 22 is connected to a wire terminal 221. One end of the wire terminal 221 is connected to the PCB board 8 through a wire. When the PCB sends an electrical signal to the electromagnetic coil, the electromagnetic coil is energized, thereby forming a magnetic field. The first moving iron core 21 is placed under the action of the magnetic field inside the electromagnetic coil and moves, thereby driving the pusher 1 to move in the cooling channel. Therefore, the cooling medium is pushed by the pusher 1 and flows in the cooling channel.

[0056] According to some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9As shown, the magnetic drive assembly 2 also includes a first stationary iron core 23, which is placed inside the first electromagnetic coil 22. The first stationary iron core 23 and the first moving iron core 21 are arranged adjacent to each other. When the first electromagnetic coil 22 is energized, the first moving iron core 21 moves toward the first stationary iron core 23.

[0057] Specifically, the first stationary iron core 23 and the first moving iron core 21 are simultaneously disposed within the first electromagnetic coil 22. When the electromagnetic coil is energized, the first stationary iron core 23 and the first moving iron core 21 generate magnetic force and interact with each other. The first moving iron core 21 is attracted by the first stationary iron core 23 and moves towards the first stationary iron core 23. A first elastic element 24 can be disposed between the first stationary iron core 23 and the first moving iron core 21. The first elastic element 24 can elastically extend and retract, causing the first moving iron core 21 to reciprocate relative to the first stationary iron core 23. The first elastic element 24 and the first moving iron core 21 abut against each other. When the electromagnetic coil is energized, the first moving iron core 21 moves towards the first stationary iron core 23, and the first elastic element 24 stores energy. When the electromagnetic coil is de-energized, the first moving iron core 21 and the first stationary iron core 23 no longer have magnetism. At this time, the first moving iron core 21 moves away from the first stationary iron core 23 under the elastic action of the first elastic element 24, so that when the electromagnetic coil is regularly energized and de-energized, the first moving iron core 21 reciprocates relative to the first stationary iron core 23. Therefore, the cooling medium can continuously flow in the cooling channel.

[0058] According to some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9 As shown, the magnetic drive assembly 2 also includes a magnetic yoke 25, which is disposed around the first stationary iron core 23 and the first moving iron core 21.

[0059] Specifically, there are four magnetic yokes 25. The four magnetic yokes 25 are connected end to end to enclose a receiving space. The first moving iron core 21, the first stationary iron core 23 and the first electromagnetic coil 22 are placed in the receiving space. The magnetic yokes 25, the first moving iron core 21 and the first stationary iron core 23 form a stable magnetic circuit, so that the first moving iron core 21 can reciprocate stably when the electromagnetic coil is energized and de-energized.

[0060] In some other embodiments, the number, size, and position of the magnetic yoke 25 can be adjusted as needed, as long as it can form a stable magnetic circuit with the first moving iron core 21 and the first stationary iron core 23.

[0061] According to some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9 As shown, the cooling device also includes a connecting rod 3, one end of which is connected to the magnetic drive assembly 2, and the other end is connected to the pusher 1.

[0062] Specifically, the magnetic drive assembly 2 includes a first moving iron core 21, a first stationary iron core 23, a first electromagnetic coil 22, and a magnetic yoke 25. One end of the connecting rod 3 is fitted with and fixedly connected to the first moving iron core 21, and the other end is connected to a pusher 1. The first stationary iron core 23 is fitted onto the connecting rod 3 and positioned between the first moving iron core 21 and the pusher 1. When the electromagnetic coil is energized, the first moving iron core 21 moves towards the first stationary iron core 23, thereby causing the pusher 1 to move away from the first stationary iron core 23. When the electromagnetic coil is de-energized, the first moving iron core 21 moves away from the first stationary iron core 23 under the action of the first elastic member 24, thereby causing the pusher 1 to move towards the first stationary iron core 23. The pusher 1 is a circular or square sheet-like structure, and one end of the connecting rod 3 is fixedly connected to the center of the pusher 1.

[0063] In some other embodiments, the magnetic drive assembly 2 is further provided with a protective housing 20, which encloses the magnetic drive assembly 2. The pusher 1 and part of the connecting rod 3 are disposed outside the protective housing 20. A sealing ring 201 is provided on the connecting rod 3 to seal the gap between the protective housing 20 and the connecting rod 3. When the cooling medium is water or other corrosive liquid, the protective housing 20 can protect the magnetic drive assembly 2 from corrosion or current interference. When the cooling medium is oil, if the oil does not corrode the drive assembly and will not be electrically charged to interfere with the magnetic drive assembly 2, the protective housing 20 may not be provided.

[0064] According to some embodiments of the present invention, such as Figure 5 , Figure 7 As shown, the cooling device also includes a first housing 4, which has a first inner cavity 41. The first inner cavity 41 is configured as part of a cooling flow channel, and the pusher 1 is placed in the first inner cavity 41.

[0065] Specifically, the cooling channel includes a conventional cooling pipe 9 and a first inner cavity 41 formed by the first housing 4. Both ends of the first housing 4 are connected to the cooling pipe 9, so that the cooling pipe 9 and the first housing 4 form a complete cooling channel. The pusher 1 is placed inside the first inner cavity 41, so that when the pusher 1 moves, it can push the cooling medium through one end of the first housing 4 from the first inner cavity 41 into the cooling pipe 9, and then through the other end of the first housing 4 from the cooling pipe 9 into the first inner cavity 41. The magnetic drive assembly 2 can be placed outside or inside the first inner cavity 41, as long as it can drive the pusher 1 to move within the first inner cavity 41.

[0066] According to some embodiments of the present invention, the inner diameter of the first inner cavity 41 is larger than the inner diameter of the remaining portion of the cooling channel, that is, the inner diameter of the first inner cavity 41 is larger than the inner diameter of the cooling pipe 9, so that the pusher 1 can be set to a correspondingly larger size, thereby generating a greater pushing force when the pusher pushes the cooling medium in the first inner cavity 41. The inner diameter of the first inner cavity 41 can be set according to requirements, and the specific size is not limited.

[0067] According to some embodiments of the present invention, such as Figure 7 , Figure 8 As shown, the magnetic drive assembly 2 and the connecting rod 3 are placed in the first inner cavity 41. In this embodiment, the magnetic drive assembly 2, the connecting rod 3 and the pusher 1 are all placed in the first inner cavity 41.

[0068] According to some embodiments of the present invention, such as Figure 3 , Figure 11 , Figure 12 As shown, the magnetic drive assembly 2 includes a drive mechanism 26 and a first magnetic element 27. The drive mechanism 26 drives the first magnetic element 27 to move, so that the first magnetic element 27 drives the pusher 1 to move.

[0069] Specifically, at least a portion of the drive mechanism 26 is magnetic, and the magnetic portion of the drive mechanism 26 can interact with the first magnetic element 27, thereby causing the first magnetic element 27 to move.

[0070] According to some embodiments of the present invention, such as Figure 3 , Figure 11 , Figure 12 As shown, the pushing member 1 includes a second magnetic member 11, which can be attracted by a first magnetic member 27 and thus move under the drive of the first magnetic member 27. The cooling device also includes a second housing 5, which forms a second inner cavity 51, which is configured as part of a cooling flow channel. The second magnetic member 11 is placed in the second inner cavity 51. The first magnetic member 27 is sleeved on the second housing 5, and attracts the second magnetic member 11 to move under the drive of the first magnetic member 27. In the direction of movement of the second magnetic member 11, sidewalls 52 are formed at both ends of the second housing 5, and through holes 521 are formed in the sidewalls 52 for allowing the cooling medium to flow into / or out of the second inner cavity 51.

[0071] Specifically, the first magnetic element 27 moves along the extension direction of the second inner cavity 51 under the drive of the drive mechanism 26. Therefore, the second magnetic element 11 can move along the extension direction of the second inner cavity 51 under the attraction of the first magnetic element 27. The two ends of the second housing 5 are respectively connected to the cooling pipe 9. The second magnetic element 11 is placed inside the second inner cavity 51. The first magnetic element 27 is set as a magnetic ring structure and is sleeved on the outside of the second housing 5. The second magnetic element 11 is set as a magnetic block, which can be square, circular, or any other shape. Multiple through holes 521 of the same or different sizes are provided on the side walls 52 at both ends of the second housing 5. The number of through holes 521 is not limited and is determined according to the required flow rate of the cooling medium. The side walls 52 are provided to prevent the second magnetic element 11 from detaching from the second inner cavity 51.

[0072] According to some embodiments of the present invention, such as Figure 3 , Figure 10 , Figure 12 As shown, the driving mechanism 26 includes: a power mechanism 261 and a push rod 262. The first end of the push rod 262 is connected to the power mechanism 261, and the second end of the push rod 262 abuts against the first magnetic element 27. The power mechanism 261 can drive the first end of the push rod 262 to move, so that the second end of the push rod 262 pushes the first magnetic element 27 to move. The power mechanism 261 also includes a second moving iron core 2611, which is connected to the first end of the push rod 262; a second stationary iron core 2612, which is arranged adjacent to the second moving iron core 2611; and a second electromagnetic coil 2613, in which the second moving iron core 2611 and the second stationary iron core 2612 are placed. When the second electromagnetic coil 2613 is energized, the second moving iron core 2611 moves toward the second stationary iron core 2612, thereby driving the first end of the push rod 262 to move.

[0073] Specifically, a spring is provided between the second stationary iron core 2612 and the second moving iron core 2611. Electromagnetic coils are provided outside the second stationary iron core 2612 and the second moving iron core 2611. The electromagnetic coils are energized and de-energized regularly under the control of the PCB board 8. When the electromagnetic coils are energized, the second moving iron core 2611 moves towards the end closer to the second stationary iron core 2612. The first end of the push rod 262 is fixedly connected to the second moving iron core 2611, thereby causing the second moving iron core 2611 to drive the first end of the push rod 262 to move towards the second stationary iron core 2612. The center of the push rod 262 is fixedly connected to the distribution box 7. When the first end of the push rod 262 moves, the second end of the push rod 262 moves in the opposite direction to the movement of the first end, thereby pushing the first magnetic component 27 to move along the extension direction of the second inner cavity 51. A connector 29 is provided between the first end of the push rod 262 and the second moving iron core 2611. The first end of the connector 29 is connected to the first end of the push rod 262, and the second end of the connector 29 is connected to the second moving iron core 2611. A limiter 291 is provided at the first end of the connector 29. The first end of the push rod 262 is connected to the first end of the connector 29 through the limiter 291 so that the push rod 262 and the connector 29 do not become disconnected.

[0074] The power mechanism 261 is connected to the electromagnetic relay 10 in the distribution box 7. When the vehicle is not charging, the electromagnetic relay 10 controls the energization and de-energization of the electromagnetic coil in the power mechanism 261 by switching the contactor on and off, thereby realizing the reciprocating motion of the second magnetic element 11 in the second inner cavity 51. When the vehicle is charging, the contactor in the electromagnetic relay 10 is always in the connected state, and the second magnetic element 11 cannot reciprocate.

[0075] In some other embodiments, the magnetic drive assembly 2 may also take another form, referred to as magnetic drive assembly A, such as... Figure 14 As shown, the power mechanism 261 includes a magnetic yoke A 111, an electromagnetic coil A 222, and a coil frame A 333. The electromagnetic coil A 222 includes a moving iron core A and a stationary iron core A. The moving iron core A is connected to a connecting rod A 444, which is connected to the pusher 1. An elastic element is provided between the moving iron core A 12 and the stationary iron core A 13. When a positive current is applied to the electromagnetic coil A 222, the moving iron core A 12 moves closer to the stationary iron core A 13. When a reverse current is applied to the electromagnetic coil A 222, the moving iron core A 12 moves away from the stationary iron core A 13 under the action of the elastic element, thereby realizing the reciprocating motion of the pusher 1.

[0076] Specifically, such as Figure 15As shown, another type of magnetic drive assembly 2 is provided with a moving iron core A12 and a stationary iron core A13. The stationary iron core A13 is provided with two units, one above the other, forming a group. The moving iron core A12 is provided between the stationary iron cores A13. A magnet 14 is also provided. The above components together constitute another type of geomagnetic drive assembly 2.

[0077] According to some embodiments of the present invention, such as Figure 3 , Figure 10 As shown, the magnetic drive assembly 2 further includes a second elastic element 28, which is connected to the first magnetic element 27 to provide elastic force to the first magnetic element 27. The direction of the elastic force is opposite to the direction of the driving force of the first magnetic element 27 by the drive mechanism 26.

[0078] Specifically, the second elastic element 28 is configured as a spring, sleeved on the second outer shell, with one end of the second elastic element 28 abutting against the first magnetic element 27. The elastic force of the second elastic element 28 on the first magnetic element 27 is opposite in direction to the pushing force of the push rod 262 on the first magnetic element 27, so that the first magnetic element 27 reciprocates under the action of the second elastic element 28 and the push rod 262.

[0079] In some embodiments, the pusher 1 may only include the pusher 1 connected to the first moving iron core 21. In this case, the magnetic drive assembly 2 only includes the first moving iron core 21, the first stationary iron core 23, the first electromagnetic coil 22, and the first elastic element 24. In some other embodiments, the pusher 1 may also include a second magnetic element 11, in which case the two different pushers 1 simultaneously push the cooling medium.

[0080] Specifically, temperature sensors are installed at key locations in the vehicle's electrical distribution box, with the key locations determined based on temperature measurement requirements.

[0081] S1: During vehicle charging, the temperature sensor detects that the temperature exceeds the temperature threshold. The PCB board 8 sends a command, and the magnetic drive assembly 2 starts working after receiving the command from the PCB board 8. As a result, the first moving iron core 21 begins to reciprocate. The frequency of the reciprocating motion of the first moving iron core 21 is determined by a combination of the temperature detected by the temperature sensor and the temperature value that needs to be cooled down. At this time, the contactor of the electromagnetic relay 10 is in the normally closed state.

[0082] S2: When the vehicle is in operation, the temperature sensor detects that the temperature exceeds the temperature threshold. The PCB board 8 sends a command, and the magnetic drive assembly 2 starts to work after receiving the command from the PCB board 8. At the same time, it determines whether the second magnetic component 11, the first magnetic component 27, the drive mechanism 26 and other cooperating structures or components need to participate in the work according to the cooling requirements. When the second magnetic component 11, the first magnetic component 27, the drive mechanism 26 and other cooperating structures or components need to participate in the work, the contactor of the electromagnetic relay 10 performs the on and off action, so that the first magnetic component 27 drives the second magnetic component 11 to reciprocate in the cooling pipe.

[0083] In some other embodiments, multiple relays may be provided, and the number of first magnetic elements 27 and second magnetic elements 11 may be the same as the number of relays. Each relay may be connected to a power mechanism 261, and each power mechanism 261 may drive one first magnetic element 27.

[0084] This invention also proposes a cooling system, such as... Figure 12 As shown, the cooling system includes a one-way valve 6, which is adapted to be installed in the cooling channel so that the cooling medium flows in one direction within the cooling channel.

[0085] Specifically, the two ends of the one-way valve 6 are connected to the cooling pipe 9, and both ends of the one-way valve 6 are threaded. The end of the cooling pipe 9 connected to the one-way valve 6 is also threaded to mate with the one-way valve 6, thus screwing the one-way valve 6 to the cooling pipe 9. The one-way valve 6 contains a spherical valve core 61 and a valve seat 62 that accommodates the valve core 61. A spring is also provided to abut against the valve core 61. When the cooling medium flows to the one-way valve 6, if the pressure of the cooling medium on the valve core 61 is greater than the spring force on the valve core 61, the valve core 61 moves away from the valve seat 62; conversely, if the pressure of the cooling medium on the valve core 61 is less than the spring force on the valve core 61, the valve core 61 is placed in the valve seat 62 to prevent liquid from flowing through the one-way valve 6.

[0086] Other embodiments of the present invention also provide a distribution box 7, such as Figure 4 , Figure 17 As shown, it includes the aforementioned cooling device or cooling system.

[0087] like Figure 17 As shown, the distribution box is divided into an upper box and a lower box, and the cooling pipes are correspondingly divided into upper cooling pipes and lower cooling pipes. The upper cooling pipes and lower cooling pipes are connected. The upper cooling pipes are located in the upper box, and the lower cooling pipes are located in the lower box.
