Description

Technical Field

[0001] The present invention relates to the technical field of oil cooling equipment, and in particular to an oil cooler capable of improving heat dissipation efficiency. Background Art

[0002] Oil coolers can be categorized as air-cooled or water-cooled, depending on the heat exchange medium. They are primarily used to cool hydraulic and lubricating oils. Oil coolers are widely used in industries such as plastics machinery, construction machinery, mining machinery, automotive, steel, wind power, and aerospace. There are many types of oil coolers. Water-cooled oil coolers are divided into tube-type and plate-type. Plate-type oil coolers are further divided into detachable plate-type and brazed plate-type. Air-cooled oil coolers are divided into tube-fin and plate-fin types.

[0003] Chinese invention patent publication number CN109779718A discloses an automotive oil cooler, comprising a housing, a mounting plate fixedly connected to the bottom of the inner wall of the housing, a mounting rod fixedly connected to the top of the mounting plate, a heat sink fixedly connected to the top of the mounting rod, a heat sink formed on both left and right sides of the housing, a heat sink mesh movably connected to the inner wall of the heat sink, and a fixing block fixedly connected to the top and bottom of the inner wall of the heat sink, the side of the fixing block near the heat sink, and the side of the fixing block near the heat sink mesh. The present invention realizes a cooler with good heat dissipation effect through the mutual cooperation between the heat sink, the heat sink, the heat sink mesh, the fixing block, the fixing shaft, the baffle, the limit groove, the limit rod, the connecting rod, the connecting spring, the heat dissipation motor, the heat dissipation shaft and the heat dissipation blades. During use, the heat sink mesh is more convenient to clean, thereby ensuring the transparency of heat dissipation, thereby achieving better heat dissipation effect.

[0004] In the oil cooling system, as the power system operates, a large amount of debris will be present in the cooling oil. Currently, this is usually filtered through magnetic attraction or filters. However, when too much metal powder is attached to the magnetic sheet, it will be magnetized for a long time, causing the powder to clump together and fall off, further affecting the power system. Passive filtration through the filter will greatly affect the cooling flow after long-term use, resulting in a decrease in cooling effect.

[0029] Example 1 like Figure 1 - Figure 2As shown, an oil cooler capable of improving heat dissipation efficiency includes an oil cooling cavity, a purification mechanism is installed inside the oil cooling cavity, the purification mechanism includes a purification mechanism main body 2, a magnetic plate 5 is embedded in the outer end surface of the purification mechanism main body 2, a scraper 3 for cleaning the magnetic plate 5 is slidably connected to the outer end surface of the purification mechanism main body 2, a capture mechanism 1 for capturing debris by inertia is provided on the top of the purification mechanism main body 2, and a fastener 4 is provided on the side of the purification mechanism main body 2 facing away from the capture mechanism 1.

[0030] Furthermore, the swing direction of the capture mechanism 1 is perpendicular to the traveling direction of the vehicle.

[0031] During use, the purification mechanism body 2 is embedded and installed inside the oil cooling cavity through fasteners 4. The fasteners 4 include but are not limited to fixing by threads or clamping. When the purification mechanism body 2 is inside the oil cooling cavity, the magnetic plate 5 can magnetically absorb magnetic metal debris. The capture mechanism 1 on the top of the purification mechanism body 2 swings continuously as the vehicle starts and stops, thereby collecting non-magnetic debris suspended inside the oil cooling cavity.

[0032] Example 2 like Figure 1 - Figure 2 As shown, on the basis of embodiment 1, the interior of the purification mechanism main body 2 is separated into a first collection chamber 6 and a partition plate 11 by a partition plate 11, and a cleaning gap 10 connected to the second collection chamber 9 is opened at the bottom of the purification mechanism main body 2, and a driven mechanism 7 for driving the scraper rod 3 to move back and forth is provided in the middle of the cleaning gap 10.

[0033] Furthermore, a connecting rod 8 is provided inside the second collecting chamber 9. The connecting rod 8 is "L"-shaped. One end of the connecting rod 8 is fixedly connected to the fastener 4, and the end of the connecting rod 8 facing away from the fastener 4 is fixedly connected to the inner wall of the second collecting chamber 9.

[0034] When in use, the first collection chamber 6 is used to collect the debris captured by the capture mechanism 1. After the magnetic plate 5 adsorbs the powder on its surface through magnetism, the scraper 3 is driven to reciprocate through the driven mechanism 7, thereby discharging the magnetic debris on the surface of the magnetic plate 5 through the cleaning gap 10 into the second collection chamber 9 for collection.

[0035] like Figure 1 - Figure 3 As shown, the capture mechanism 1 includes a counterweight arc 14, a second arc-shaped filter screen 15, a rotating ring 16, a rotating rod 17 and a deflection ring 19. The deflection ring 19 is rotatably connected to the inside of the first collecting chamber 6 through the rotating rod 17. The rotating ring 16 is rotatably connected to the outer end face of the deflection ring 19. The second arc-shaped filter screen 15 is fixedly connected to the upper end of the rotating ring 16. The counterweight arc 14 is fixedly connected to the end of the second arc-shaped filter screen 15 away from the rotating ring 16. The rotating ring 16 is elastically connected to the surface of the partition plate 11 through the connecting rod 20.

[0036] Furthermore, the second curved filter screen 15 is arranged in an arc shape, and the connecting rods 20 can be provided in multiple groups and evenly arranged along the upper end surface of the partition plate 11.

[0037] During use, the deflection ring 19 is rotated and arranged inside the first collecting chamber 6 through the rotating rod 17, and the rotating ring 16 is elastically connected to the partition plate 11 through the connecting rod 20, so that the deflection ring 19 and the rotating ring 16 are in a horizontal state in the default state. When the vehicle starts or brakes, since the counterweight arc 14 on the top of the second arc-shaped filter screen 15 is made of highly sealed metal material, the deflection ring 19 drives the second arc-shaped filter screen 15 to swing under the action of the relationship, thereby capturing impurities in the oil.

[0038] like Figure 1 - Figure 9 As shown, the driven mechanism 7 includes a first bevel gear 18, a second bevel gear 23 and a rotating rod 25. The rotating rod 17 passes through the deflection ring 19 and extends to the middle of the deflection ring 19. The first bevel gear 18 is fixedly sleeved on the outer end surface of the rotating rod 17. The rotating rod 25 is embedded in the middle of the partition plate 11. The second bevel gear 23 is fixedly connected to the top of the rotating rod 25. The second bevel gear 23 and the rotating rod 17 are meshed. The rotating rod 25 is elastically connected to the partition plate 11 through a vortex spring 24. The upper end surface of the deflection ring 19 is provided with a first arc filter 12 that fits with the second arc filter 15.

[0039] Furthermore, a cleaning rod 13 is provided on the inner wall of the counterweight arc 14 and is in contact with the surface of the first arc-shaped filter screen 12 .

[0040] When in use, by providing the first curved filter screen 12 and the second curved filter screen 15, the two sets of settings improve the filtering effect of the oil, and the deflection ring 19 in the capture mechanism 1 will deflect along the rotating rod 17 as the relationship works, thereby driving the first curved filter screen 12 and the second curved filter screen 15 to swing, and the deflection ring 19 will drive the rotating rod 17 to rotate while deflecting, and the rotating rod 17 drives the rotation of the rotating rod 25 through the first bevel gear 18 and the second bevel gear 23, and the rotating rod 25 drives the partition plate 11 to rotate through the vortex spring 24, and the connecting rod 20 is connected to the cleaning rod 13, so that when the deflection ring 19 deflects, the partition plate 11 drives the cleaning rod 13 to rotate. The sorting rod 13 rotates, and the cleaning rod 13 and the deflection ring 19 are connected in rotation, so that the cleaning rod 13 can drive the second curved filter screen 15 to rotate along the surface of the first curved filter screen 12, so that the first curved filter screen 12 and the second curved filter screen 15 slide alternately, and then the contact surface of the first curved filter screen 12 and the second curved filter screen 15 is cleaned by sliding to avoid blockage, and the counterweight arc 14 can also be provided with a cleaning rod 13, and the cleaning rod 13 rotates synchronously with the second curved filter screen 15 to clean the inner side of the first curved filter screen 12, so as to avoid the adhesion of debris on the surface of the first curved filter screen 12 and the second curved filter screen 15 to affect the cleaning effect.

[0041] Furthermore, the cross section of the scraper rod 3 is trapezoidal.

[0042] like Figure 1 - Figure 7 and Figure 10 - Figure 11 As shown, the magnetic plate 5 is provided with a sliding groove 36 , the sliding groove 36 is elastically connected to an elastic slider 37 , the scraper rod 3 is fixedly connected to the elastic slider 37 , and the bottom of the partition plate 11 is provided with an inclined panel 38 that fits with the elastic slider 37 .

[0043] Furthermore, the inclined panel 38 is arranged in an arc shape.

[0044] During use, the partition plate 11 will rotate as the capture mechanism 1 deflects under the drive of the driven mechanism 7, and an inclined panel 38 is provided at the bottom of the partition plate 11. The elastic slider 37 elastically fits with the surface of the inclined panel 38 under the elastic action, so that as the partition plate 11 rotates, the inclined panel 38 will make the elastic slider 37 slide back and forth inside the sliding groove 36, thereby driving the scraper rod 3 to slide back and forth along the surface of the magnetic attraction plate 5, thereby pushing the attached magnetic debris into the interior of the second collection chamber 9 through the cleaning gap 10.

[0045] like Figure 1 - Figure 10 As shown, a delay control mechanism is provided between the rotating rod 25 and the partition plate 11, and the delay control mechanism includes a driven rod 26, a driving cross rod 27 and a pin rod 32. The driven rod 26 is movably arranged in the middle of the rotating rod 25, and the driven rod 26 and the first bevel gear 18 are respectively engaged with the rotating rod 25 and the rotating rod 17 in one direction. The driving cross rod 27 is fixedly connected to the two ends of the driven rod 26, and the pin rod 32 is fixedly connected to the side where the driving cross rod 27 is in contact with the partition plate 11, and a pin groove 35 adapted to the pin rod 32 is provided at the bottom of the partition plate 11. The end of the driving cross rod 27 facing away from the driven rod 26 is slidably connected to the inner wall of the second collecting chamber 9.

[0046] Furthermore, a vertical sliding groove adapted to the driving cross bar 27 is provided on the inner wall of the second collecting chamber 9 , thereby limiting the rotation of the driven rod 26 .

[0047] When in use, the driven rod 26 and the first bevel gear 18 are unidirectionally meshed with the rotating rod 25 and the rotating rod 17 respectively, so that when the capture mechanism 1 is deflected, the first bevel gear 18 will rotate unidirectionally and drive the second bevel gear 23 to rotate. The second bevel gear 23 will also rotate unidirectionally, and the partition plate 11 cannot rotate under the pin connection of the pin rod 32 and the pin groove 35, so that the partition plate 11 also rotates the vortex spring 24 between the rod 25 and the pin is continuously compressed until the second bevel gear 23 rotates to the appropriate position, and the pin rod 32 disengages from the pin groove 35. Due to the unidirectional limit of the rotating rod 25, the partition plate 11 can rotate to drive the reciprocating movement of the scraper rod 3 and the rotation and cleaning of the second curved filter screen 15, and preferably, the second curved filter screen 15 still overlaps with the first curved filter screen 12 after rotation, thereby improving the cleaning effect of the first curved filter screen 12. At the same time, impurities on the inner side of the first curved filter screen 12 can fall off and be collected inside the first collecting chamber 6 as it rotates.

[0048] like Figure 1-10 As shown, a ratchet 29 is provided on the outer end surface of the driven rod 26 , and a pawl 28 adapted to the ratchet 29 is provided on the inner wall of the rotating rod 25 .

[0049] Furthermore, one-way driving can also be achieved between the first bevel gear 18 and the rotating rod 17 via the pawl 28 and the ratchet 29 .

[0050] During use, the first bevel gear 18 and the rotating rod 25 can only rotate in one direction due to the arrangement of the pawl 28 and the ratchet 29 .

[0051] like Figure 1 - Figure 11 As shown, a driving block 31 is provided on the outer end face of the driven rod 26, and a driving groove 30 adapted to the driving block 31 is provided inside the rotating rod 25. The driving groove 30 includes an oblique groove 33 and a vertical groove 34. The oblique groove 33 and the vertical groove 34 are connected to each other, and the driving cross rod 27 is elastically connected to the inside of the second collecting chamber 9.

[0052] Furthermore, the ratchet 29 on the outer end surface of the driven rod 26 is set with an interference fit.

[0053] When the cam 32 is in engagement with the pin slot 35, the drive bar 27 is able to move the drive block 31 upwards and back along the vertical slot 34, thereby releasing the stopper 32 from moving.

[0054] like Figure 1 - Figure 4 As shown, the connecting rod 20 includes a rotating connecting member 21 and an elastic telescopic rod 22. The rotating connecting member 21 is slidably connected to the lower end surface of the cleaning rod 13, and the elastic telescopic rod 22 is elastically connected to the bottom of the rotating connecting member 21. The end of the elastic telescopic rod 22 facing away from the rotating connecting member 21 is fixedly connected to the upper end surface of the partition plate 11.

[0055] When in use, the partition plate 11 elastically supports the capture mechanism 1 through the elastic telescopic rod 22, and the elastic telescopic rod 22 is rotatably connected to the cleaning rod 13 through the rotating connecting piece 21. At the same time, the rotating connecting piece 21 is slidably connected to the bottom of the cleaning rod 13, so that the elastic telescopic rod 22 will not affect the inclination and deflection of the cleaning rod 13 while elastically supporting. The specific rotating connecting piece 21 can be limited by setting a slider and a slide groove that are compatible with the deflection direction of the cleaning rod 13, so that the partition plate 11 can also drive the cleaning rod 13 to rotate through the elastic telescopic rod 22.

[0056] Working principle: The purification mechanism body 2 is embedded and installed inside the oil cooling chamber through fasteners 4. The fasteners 4 include but are not limited to being fixed by threads or clamping. When the purification mechanism body 2 is inside the oil cooling chamber, the magnetic plate 5 can absorb magnetic metal debris by magnetic attraction. The capture mechanism 1 on the top of the purification mechanism body 2 swings continuously as the vehicle starts and stops, thereby collecting the non-magnetic debris suspended inside the oil cooling chamber. The first collection chamber 6 is used to collect the debris captured by the capture mechanism 1. After the magnetic plate 5 adsorbs the powder on its surface through magnetism, the scraper 3 is driven to reciprocate by the driven mechanism 7, thereby discharging the magnetic debris on the surface of the magnetic plate 5 into the second collection chamber 9 through the cleaning gap 10 for collection. The deflection ring 19 is rotated by the rotating rod 17 and is set in the first collection chamber. 6, and the rotating ring 16 is elastically connected to the partition plate 11 through the connecting rod 20, so that the deflection ring 19 and the rotating ring 16 are in a horizontal state in the default state. When the vehicle starts or brakes, since the counterweight arc 14 on the top of the second arc-shaped filter 15 is made of highly sealed metal material, the deflection ring 19 drives the second arc-shaped filter 15 to swing under the action of the relationship, thereby achieving the capture of impurities in the oil. By providing the first arc-shaped filter 12 and the second arc-shaped filter 15, the two sets of settings improve the filtering effect of the oil, and the deflection ring 19 in the capture mechanism 1 will deflect along the rotating rod 17 as the relationship works, thereby driving the first arc-shaped filter 12 and the second arc-shaped filter 15 to swing, and the deflection ring 19 will drive the rotating ring 19 while deflecting. The rod 17 rotates, and the rotating rod 17 drives the rotation of the rotating rod 25 through the first bevel gear 18 and the second bevel gear 23. The rotating rod 25 drives the partition plate 11 to rotate through the vortex spring 24, and the connecting rod 20 is connected to the cleaning rod 13, so that when the deflection ring 19 deflects, the partition plate 11 drives the cleaning rod 13 to rotate, and the cleaning rod 13 and the deflection ring 19 are connected in rotation, so that the cleaning rod 13 drives the second arc filter 15 to rotate along the surface of the first arc filter 12, so that the first arc filter 12 and the second arc filter 15 slide alternately, and then the contact surface of the first arc filter 12 and the second arc filter 15 is cleaned by sliding to avoid clogging, and the counterweight arc 14 can also be provided with a cleaning rod 13, which moves along with the second arc filter 1 5 rotates synchronously to clean the inside of the first curved filter screen 12, preventing debris from adhering to the surfaces of the first curved filter screen 12 and the second curved filter screen 15 and affecting the cleaning effect. The partition plate 11 rotates with the deflection of the capture mechanism 1 under the drive of the driven mechanism 7, and an inclined plate 38 is provided at the bottom of the partition plate 11. The elastic slider 37 elastically fits with the surface of the inclined plate 38 under the elastic action, so that as the partition plate 11 rotates, the inclined plate 38 will make the elastic slider 37 slide back and forth inside the sliding groove 36, thereby driving the scraper 3 to slide back and forth along the surface of the magnetic suction plate 5, thereby pushing the attached magnetic debris into the interior of the second collection chamber 9 through the cleaning gap 10. The driven rod 26 and the first bevel gear 18 are unidirectionally meshed with the rotating rod 25 and the rotating rod 17 respectively.When the capture mechanism 1 is deflected, the first bevel gear 18 will rotate in one direction and drive the second bevel gear 23 to rotate. The second bevel gear 23 will also rotate in one direction, and the partition plate 11 cannot rotate under the pin connection between the pin rod 32 and the pin groove 35, so that the partition plate 11 also rotates the vortex spring 24 between the rods 25 and continuously compresses until the second bevel gear 23 rotates to a suitable position, and the pin rod 32 disengages from the pin groove 35. Due to the one-way limit of the rotating rod 25, the partition plate 11 can rotate to drive the reciprocating scraper rod 3 and the rotation of the second arc filter 15 for cleaning, and the preferred second arc filter 15 rotates After the rotation, it still overlaps with the first curved filter screen 12 for the best, thereby improving the cleaning effect of the first curved filter screen 12. At the same time, impurities on the inner side of the first curved filter screen 12 can fall off and be collected inside the first collecting chamber 6 as it rotates. The arrangement of the pawl 28 and the ratchet 29 makes the first bevel gear 18 and the rotating rod 25 only rotate in one direction. When the rotating rod 25 rotates in one direction, a rotation angle difference will be generated between the driven rod 26 and the driving cross bar 27, so that the driving block 31 on the outer end face of the driven rod 26 slides inside the driving groove 30. When the driving block 31 slides inside the inclined groove 33, it will When the driven rod 26 is driven by the slot 33, it moves downward relative to the rotating rod 25. When the driving block 31 slides to the end of the inclined slot 33 and enters the vertical slot 34, as the driven rod 26 drives the driving cross bar 27 to move downward, the driving cross bar 27 will drive the pin rod 32 to separate from the pin slot 35, thereby releasing the limit on the partition plate 11, and then the elastic potential energy inside the vertical slot 34 is released to drive the partition plate 11 to rotate, completing the driving of the scraper rod 3 and the cleaning rod 13. After the release is completed, when the pin rod 32 and the pin slot 35 are re-adapted, the driving cross bar 27 will drive the driving block 31 to move up and reset along the vertical slot 34 under the action of the elastic force. , and the partition plate 11 is re-positioned. The partition plate 11 elastically supports the capture mechanism 1 through the elastic telescopic rod 22, and the elastic telescopic rod 22 is rotatably connected to the cleaning rod 13 through the rotating connector 21. At the same time, the rotating connector 21 is slidably connected to the bottom of the cleaning rod 13, so that the elastic telescopic rod 22 will not affect the tilt and deflection of the cleaning rod 13 while providing elastic support. Specifically, the rotating connector 21 can be limited by setting a slider and a slide groove that are compatible with the deflection direction of the cleaning rod 13, so that the partition plate 11 can also drive the cleaning rod 13 to rotate through the elastic telescopic rod 22.
