The friction disc 8 includes two contact pads 801, and a closed membrane 802 is fixedly connected between the sides of the two contact pads 801. A plurality of elastic columns 803 distributed around the two contact pads 801 are fixedly connected between the side walls, and the elastic columns 803 are made of high elastic material (polyurethane elastic material is preferably used, and other materials can also be selected according to actual needs). The elastic columns 803 rely on elastic force to make the outer contact pad 801 closely attached to the side wall of the stepped tower wheel 2. During the rotation of the stepped tower wheel 2, the contact pad 801 is driven by friction to rotate with it, so that the shrinking vibration filter cartridge 9 is rotated, which can effectively save energy consumption, and also make the shrinking vibration filter cartridge 9 rely on centrifugal force during the rotation to effectively improve the filtering effect of the coolant; Figure 4 It is shown that a shrinking and vibrating filter cartridge 9 is placed inside the heat dissipation box 4, and a porous water inlet pipe 6 penetrates into the inside of the shrinking and vibrating filter cartridge 9, a turntable 501 is rotatably connected to the inner wall of the closed door 5, and the shrinking and vibrating filter cartridge 9 abuts against the turntable 501, a plurality of equally spaced and surrounding magnetic strips 10 are fixedly connected to the inner wall of the heat dissipation box 4, and the magnetic strips 10 and the shrinking and vibrating filter cartridge 9 magnetically repel each other, and water outlet pumps 11 are installed on the inner walls of the heat dissipation box 4 on both sides of the shrinking and vibrating filter cartridge 9 (the specific model is selected according to actual needs and will not be described in detail here), and the water outlet end of the water outlet pump 11 is connected to the inside of the water tank 101 through a water pipe.

[0022] The second implementation method: Figure 8 , 9 , 10 and Fig.11As shown, the shrinkage vibration filter cartridge 9 includes an inner plate 901 and an outer plate 902, the side walls of the inner plate 901 and the outer plate 902 are both provided with mounting grooves 9021, and a filter cartridge 903 is placed between the two mounting grooves 9021, the filter cartridge 903 includes a plurality of filter segments 9031 distributed around at equal intervals, the filter segment 9031 includes a porous elastic pad 12 (preferably made of waterproof rubber material, and other materials can also be selected according to actual needs), and a flexible filter screen 13 (preferably made of polyester fiber material, and other materials can also be selected according to actual needs) is fixedly connected to the inner side of the porous elastic pad 12 ), the porous elastic pad 12 plays a role in supporting the flexible filter screen 13, and at the same time, the elastic force of the porous elastic pad 12 can make it vibrate under the drive of the moving section 9032, so as to shake off the metal debris on the flexible filter screen 13, and a moving section 9032 is fixedly connected between each two adjacent filter cartridges 903, and the slider 904 is installed on the moving section 9032. The filter section 9031 plays a role in filtering the coolant. The moving section 9032 moves repeatedly under the action of magnetic repulsion and centrifugal force, thereby driving the filter section 9031 to contract and vibrate, thereby achieving the purpose of self-cleaning of the filter cartridge 903; Fig.12 As shown, the moving section 9032 includes a hard moving sheet 14 (plastic material is preferably selected, and other materials can also be selected according to actual needs), and the inner wall of the hard moving sheet 14 is fixedly inlaid with a magnetic sheet 15 that magnetically repels the magnetic strip 10. The magnetic sheet 15 and the magnetic strip 10 magnetically repel each other, and the hard moving sheet 14 plays a shaping role. Under the magnetic repulsive force, the hard moving sheet 14 moves inward, and the hard moving sheet 14 then drives the filter section 9031 to shrink inward. At the same time, the centrifugal force causes the hard moving sheet 14 to reset. The two forces act back and forth to cause the hard moving sheet 14 to move repeatedly, so that the filter section 9031 vibrates, thereby achieving a self-cleaning effect of the filter section 9031; Figure 5 , 9As shown, the side walls at both ends of the filter cartridge 903 are fixedly connected with a plurality of sliders 904 distributed at equal intervals, and the inner wall of the mounting groove 9021 is provided with a plurality of slide grooves 905 matching the sliders 904, a water inlet is provided on the side wall at the center of the inner disk 901, and a sealing connection sleeve 906 is fixedly connected to the side wall of the inner disk 901 located at the water inlet, an annular groove is provided on the inner wall of the sealing connection sleeve 906, and a sealing snap ring 9061 is fixedly connected to the inner wall of the annular groove through a spring, and an annular groove matching the sealing snap ring 9061 is provided on the side wall of the multi-porous water inlet pipe 6, and after the sealing connection sleeve 906 is sleeved on the multi-porous water inlet pipe 6, the sealing snap ring 9061 is snapped together with the annular groove to realize the multi-porous water inlet pipe 6. The sealed connection with the sealing connection sleeve 906, so that the porous water inlet pipe 6 will drive the shrinking and vibrating filter cartridge 9 to rotate together under the drive of the stepped tower wheel 2, which makes it convenient to disassemble the shrinking and vibrating filter cartridge 9 for cleaning. The sealing connection sleeve 906 is sleeved on the porous water inlet pipe 6, and the sealing connection sleeve 906 is clamped with the porous water inlet pipe 6. The coolant inside the water tank 101 enters the shrinking and vibrating filter cartridge 9 through the porous water inlet pipe 6. The coolant is filtered when passing through the filter cartridge 903. The filter cartridge 903 can shrink and vibrate under the action of centrifugal force and the magnetic repulsion force of the magnetic strip 10, so as to shake off the metal debris attached to the filter cartridge 903, and effectively prevent the metal debris from accumulating on the filter cartridge 903 and clogging it.

[0023] The working principle of this scheme is as follows: the coolant inside the water tank 101 enters the interior of the shrinking and vibrating filter cartridge 9 through the holes on the porous water inlet pipe 6, and the elastic column 803 relies on the elastic force to make the contact pad 801 tightly attached to the side wall of the stepped tower wheel 2. When the stepped tower wheel 2 rotates, the friction force drives the friction disk 8 and the porous water inlet pipe 6 to rotate, and the sealing clamp ring 9061 is clamped with the porous water inlet pipe 6, so that the shrinking and vibrating filter cartridge 9 is driven to rotate by the porous water inlet pipe 6. During the rotation of the shrinking and vibrating filter cartridge 9, the centrifugal force causes the metal debris to settle on the shrinking and vibrating filter cartridge 9, and the heat sink 4 absorbs the heat of the coolant and exchanges heat with the outside air to achieve effective cooling. The water outlet pump 11 draws the coolant back into the water tank 101 to achieve circulating filtration of the coolant. During the rotation of the shrinking and vibrating filter cartridge 9, when the moving section 9032 is facing the magnetic strip 10, the two The magnetic repulsion effect causes the moving section 9032 to move inward, and the moving section 9032 drives the filter section 9031 to shrink inward. When the moving section 9032 rotates past the magnetic strip 10, the centrifugal force causes the moving section 9032 to quickly reset. Such alternating action causes the moving section 9032 to move back and forth, and then causes the filter section 9031 to shrink and vibrate, thereby effectively preventing a large amount of metal debris from accumulating on the filter section 9031 and causing blockage, thereby achieving an effective self-cleaning effect. When the shrinking and vibrating filter cartridge 9 needs to be replaced and maintained, the closing door 5 is opened to pull out the shrinking and vibrating filter cartridge 9. When a new shrinking and vibrating filter cartridge 9 is installed, the shrinking and vibrating filter cartridge 9 is inserted into the porous water inlet pipe 6, and the sealing clamp 9061 is clamped with the porous water inlet pipe 6. Finally, the closing door 5 is closed, and the turntable 501 is pressed against the outer disk 902 to stabilize it.

[0024] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
