[0046] As shown in FIGS. 1-4, a vibration cooling pump 100 includes a housing 10, a pump diaphragm 20, control valves 30, and a vibrating assembly 40. The housing 10 has an accommodation space 11, and the pump diaphragm 20 is disposed within the accommodation space 11, dividing the accommodation space 11 into a relatively sealed pump chamber 111 and vibration chamber 112. The pump chamber 111 is provided with a water inlet 113 and a water outlet 114. The control valves 30 are disposed at the water inlet 113 and water outlet 114 correspondingly, and the vibration assembly 40 is disposed within the vibration chamber 112. The vibration assembly 40 includes a magnetic circuit system 41 and a drive coil 42 arranged opposite to each other. One of the magnetic circuit system 41 or the drive coil 42 serves as the vibrator, and the other serves as a stator. The magnetic circuit system 41 is provided with a magnetic gap 411, and the drive coil 42 is inserted into the magnetic gap 411. The vibrator is connected to the pump diaphragm 20, the stator is fixedly connected to the housing 10, and the drive coil 42 cooperates with the magnetic circuit system 41 to drive the pump diaphragm 20 to vibrate, so as to control an open / closed state of the control valve 30. The working principle of the cooling pump of the present application utilizes the cooperation between the magnetic circuit system 41 and the drive coil 42 to drive the pump diaphragm 20 (when current flows through the drive coil 42, a magnetic field is generated, which interacts with the magnetic field of the magnetic circuit system 41 to produce an electromagnetic force, i.e., the Lorentz force), causing it to perform reciprocating motion, thereby achieving the pumping effect.
[0047] In the present application, the vibration cooling pump 100 includes a vibration assembly 40 and a pump diaphragm 20, integrating the functions of a conventional vibration motor and a cooling pump into a single unit. This design achieves a compact design for the cooling pump. Additionally, in the present application, the vibration assembly 40 is directly mounted on the pump diaphragm 20, enabling direct transmission of vibrations to the pump diaphragm 20. Therefore, the present application achieves both a compact structure and maximized vibration, which is advantageous for energy efficiency design.
[0048] As shown in FIGS. 4, 6, and 8, in some embodiments, the vibration cooling pump 100 further includes an electrical connecting member 80, which is disposed within the vibration chamber 112 and connected to the drive coil 42.

[0049] In some embodiments, the housing 10 is cylindrical in shape, and the vibration assembly 40 and pump diaphragm 20 are arranged sequentially along an axial direction of the housing 10. The magnetic circuit system 41 is fixed to the pump diaphragm 20, and the magnetic gap 411 is formed on a side of the magnetic circuit system 41 facing a top wall 12 of the housing 10. One side of the drive coil 42 is fixed to the top wall 12 of the housing 10, and the other side of the drive coil 42 is inserted into the magnetic gap 411. This design adopts a moving magnet design, where the drive coil 42 (the drive coil is the stator) is fixed to the top wall 12 of the housing 10, and the magnetic circuit system 41 (the magnetic circuit system is the vibrator) is fixed to the pump diaphragm 20. When the magnetic circuit system 41 and the drive coil 42 interact along the axial direction (vertical direction) of the housing 10, the magnetic circuit system 41 and the pump diaphragm 20 vibrate synchronously.
[0050] In some embodiments, the housing 10 is cylindrical, and the vibration assembly 40 and the pump diaphragm 20 are arranged sequentially along the axial direction of the housing 10. The magnetic circuit system 41 (the magnetic circuit system is a stator) is fixed to the top wall 12 of the housing 10, and the magnetic gap 411 is formed on a side of the magnetic circuit system 41 facing the bottom wall 13 of the housing 10. One side of the drive coil 42 (the drive coil is a vibrator) is fixed to the pump diaphragm 20, and the other side of the drive coil 42 is inserted into the magnetic gap 411. This design adopts a moving coil design, where the drive coil 42 is fixed to the pump diaphragm 20, and the magnetic circuit system 41 is fixed to the top wall 12 of the housing 10. When the magnetic circuit system 41 and the drive coil 42 interact along the axial direction (vertical direction) of the housing 10, the drive coil 42 and the pump diaphragm 20 vibrate synchronously.
[0051] In some embodiments, the magnetic circuit system 41 includes a magnetic bowl 412 and an inner magnet 413 disposed within the magnetic bowl 412 and spaced apart from the magnetic bowl 412. An inner wall of the magnetic bowl 412 and an outer wall of the inner magnet 413 jointly define the magnetic gap 411.

The magnetic circuit system 41 and the drive coil 42 are arranged oppositely along s thickness direction (vertical direction) of the housing 10. The vibrator (the vibrator being either the magnetic circuit system 41 or the drive coil 42) is fixed to the mass block 43 and drives the mass block 43 to vibrate. Specifically, when the magnetic circuit system 41 and the drive coil 42 interact along the length direction (horizontal direction) of the housing 10, the mass block 43 drives the pump diaphragm 20 to vibrate synchronously.

This design adopts a moving magnet design, where the drive coil 42 is fixed to the bottom wall 13 of the housing 10, the magnetic circuit system 41 is fixed to the mass block 43. When the magnetic circuit system 41 and the drive coil 42 interact along the length direction (horizontal direction) of the housing 10, the magnetic circuit system 41 moves the mass block 43 along the length direction of the housing 10 under the force, and synchronously transmits the force to the pump diaphragm 20 through the mass block 43, thereby driving the pump diaphragm 20 to vibrate synchronously.
[0055] In some embodiments, the magnetic circuit system 41 (the magnetic circuit system being the stator) is fixed to the bottom wall 13 of the housing 10, and the drive coil 42 (the drive coil being the vibrator) is fixed to the mass block 43 and spaced apart from the magnetic circuit system 41. This design adopts a moving coil design, where the drive coil 42 is fixed to the mass block 43, and the magnetic circuit system 41 is fixed to the bottom wall 13 of the housing 10. When the magnetic circuit system 41 and the drive coil 42 interact along the length direction (horizontal direction) of the housing 10, the drive coil 42 moves the mass block 43 along the length direction of the housing 10 under the force, and synchronously transmits the force to the pump diaphragm 20 through the mass block 43, thereby causing the pump diaphragm 20 to vibrate synchronously.
[0056] In some embodiments, the magnetic circuit system 41 includes a first magnet 414 and a second magnet 415 spaced apart opposite to each other along the length direction of the housing 10, and an intermediate magnetic portion 416 disposed between the first magnet 414 and the second magnet 415. The winding hole 421 of the drive coil 42 corresponds to the intermediate magnetic portion 416.

[0067] As shown in FIGS. 9-11, the second aspect of the present application provides a cooling structure including a cooling plate 200 and the aforementioned vibration cooling pump 100. The cooling plate 200 is provided with a cooling channel 201, as well as a liquid inlet 202 and a liquid outlet 203 connected to the cooling channel 201.
[0068] At least two vibration cooling pumps 100 are arranged on the cooling plate 200. The water inlet 113 of each vibration cooling pump 100 is connected to the liquid inlet 202 correspondingly, and the water outlet 114 of each vibration cooling pump 100 is connected to the liquid outlet 203 correspondingly. The vibration directions of the vibrators of the at least two vibration cooling pumps 100 are the same or opposite.
[0069] As shown in FIG. 12, the third aspect of the present application provides a control method for a cooling pump, which is implemented by the aforementioned cooling structure, including the following steps.
[0070] S101, obtaining an operation command.
[0071] The operation command may be obtained through one or more of the following methods: a user interface, an external control system, or a sensor.
[0072] S102, determining whether the current operating mode is pumping mode or vibration mode according to the received operation command.
[0073] Specifically, in one embodiment, if the selection is made via the user interface, the mode is determined as pumping mode or vibration mode according to the user's direct input.
[0074] In another embodiment, according to a preset program design, the mode is automatically determined as pumping mode or vibration mode according to the current task phase being executed.
[0075] In another embodiment, according to sensor feedback design, the mode is determined as pumping mode or vibration mode when the operating conditions detected by the sensors within the cooling channels (such as pressure, flow rate, etc.) meet the predefined conditions.

[0077] S103, if it is determined to be in pumping mode, providing input signals with a phase difference set to 180° to at least one pair of vibration cooling pumps, to cause the vibrators in each pair of vibration cooling pumps to vibrate in opposite directions.
[0078] S104, if it is determined to be in vibration mode, providing input signals with the same phase to each pair of vibration cooling pumps, to cause the vibrators in all vibration cooling pumps to vibrate in the same direction.
[0079] The present application provides a cooling pump control method, including:
[0080] Setting one or more pairs of vibration cooling pumps 100 (i.e., two or an even number of vibration cooling pumps) to operate simultaneously on the cooling plate 200. When only the pump function is required and the vibration function is not needed, the input signals for the two cooling pumps have a phase difference of 180°, causing the vibrators (which are either the magnetic circuit system 41 or the drive coil 42) in the two pumps to vibrate in opposite directions, thereby canceling out the vibrations. as shown in the figures.
[0081] When tactile feedback is required, the input signals of the two vibration pumps are identical, causing the vibrators in both pumps to vibrate in the same direction, with the vibrations overlapping to produce a tactile sensation.
[0082] In the case of an even number of pumps, arranging half of the vibrators to vibrate in the opposite direction to the other half achieves phase cancellation.
[0083] The present application addresses the issue of unnecessary vibrations generated by multiple cooling pumps during the cooling process.
[0084] As shown in FIGS. 9 and 11, the two cooling pumps are disposed in reverse (i.e., the two vibration cooling pumps 100 are arranged opposite to each other, with their pump chambers 111 positioned close to each other). By inputting signals with the same phase to the two vibration cooling pumps 100, the vibration directions of the two pumps are made opposite, thereby achieving vibration cancellation.
[0085] It should be understood that the above embodiments are merely illustrative examples used to explain the principles of the present application, but the present application is not limited thereto. For those skilled in the art, various modifications and improvements may be made without departing from the spirit and scope of the present application, and such modifications and improvements are also considered within the scope of the present application.
