Description

Technical Field

[0001] This invention relates to the field of cooler technology, specifically to an all-aluminum heat dissipation cooler for automobile engines. Background Technology

[0002] When an all-aluminum radiator for a car engine is in operation, coolant enters the radiator through the inlet pipe. To ensure the long-term stable use of the radiator, a filter is installed in the inlet pipe to filter impurities in the coolant and prevent them from accumulating inside the radiator and affecting its heat dissipation efficiency. The existing filter and the inlet pipe design limit the number of filter holes that coolant can pass through to the cross-sectional area of ​​the inlet pipe. This results in a relatively small range of filter holes, making the filter more prone to clogging. Consequently, the filter's lifespan is shorter, and the existing filter is not easy to install or remove, making it inconvenient for replacement or cleaning during later use. Summary of the Invention

[0003] The purpose of this invention is to provide an all-aluminum heat sink for automotive engines, in order to solve the problems mentioned in the background art, such as the small range of coolant flow through filter holes and the inconvenience of filter installation and removal, making it difficult to replace or clean the filter later.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A full-aluminum heat dissipation cooler for automobile engines includes a cooler body, with a water inlet chamber fixedly disposed at one end of the cooler body and a water outlet chamber fixedly disposed at the other end. A water inlet pipe is fixedly disposed on the water inlet chamber and a water outlet pipe is fixedly disposed on the water outlet chamber. The cooler body also includes a first filter assembly, which is installed in the water inlet pipe.

[0006] The second filter assembly is installed on the first filter assembly and works in conjunction with the first filter assembly to filter the coolant;

[0007] A linkage drive component is installed in the water inlet chamber and moves through the first filter component, and also drives the second filter component to move.

[0008] A filter assembly locking mechanism is installed in the water inlet pipe to lock the first filter assembly.

[0009] Furthermore, the first filter assembly includes a filter holder, which is inserted into the water inlet pipe;

[0010] The first filter cartridge is movably mounted on the filter support.

[0011] Furthermore, the filter holder has an installation cavity inside, and the first filter cartridge is partially inserted into the filter holder to cooperate with the first filter cartridge to filter the coolant.

[0012] Furthermore, the second filter assembly is a second filter cartridge, and there are two second filter cartridges, which are symmetrically installed on the first filter cartridge.

[0013] Furthermore, the second filter cartridge works in conjunction with the first filter cartridge to filter the coolant.

[0014] Furthermore, the linkage drive component includes: a movable mating block, which is movably installed in the water inlet chamber;

[0015] The linkage support block consists of two blocks that are movably connected to the movable cooperation block.

[0016] Furthermore, the movable mating block cooperates with the first filter cylinder, and the movable mating block is moved by the first filter cylinder.

[0017] Furthermore, when the movable mating block moves, it drives the linkage support block to move as well.

[0018] Furthermore, the linkage support block cooperates with the second filter cylinder, and the linkage support block drives the second filter cylinder to move.

[0019] Furthermore, the filter assembly locking mechanism includes: a mounting lock bar, which is inserted into the water inlet pipe;

[0020] Two movable locking rods are symmetrically installed on the mounting lock bar.

[0021] Furthermore, the first filter cartridge is locked by the movable locking rod, and the filter support cartridge is locked by the first filter cartridge.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0023] 1. By setting a first filter cartridge on the filter support, after the filter support is installed into the water inlet pipe, the first filter cartridge enters the water inlet chamber. The filter holes on the bottom and sides of the first filter cartridge can be fully exposed on the outside of the filter support, which can effectively increase the number of filter holes through which the coolant passes.

[0024] 2. A second filter cartridge is also installed on the first filter cartridge. As the first filter cartridge moves, the second filter cartridge will also move to the outside of the first filter cartridge. This will expose the filter holes on the second filter cartridge to the outside of the first filter cartridge and into the water inlet chamber, further increasing the number of filter holes through which the coolant passes and thus extending its service life.

[0025] 3. In addition, before installation, the second filter cartridge is stored inside the first filter cartridge, which allows the filter holder to be easily inserted into the water inlet pipe for installation. The filter holder and the first filter cartridge are fixed by the installation lock strip, making the installation convenient and quick, and facilitating its replacement or cleaning later.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This invention provides a technical solution:

[0043] like Figure 1 and Figure 2 As shown, an all-aluminum heat sink for an automobile engine includes a cooler body 1. One end of the cooler body 1 is fixedly provided with a water inlet chamber 11 by welding, and the other end is fixedly provided with a water outlet chamber 12 by welding. A water inlet pipe 13 is fixedly provided on the water inlet chamber 11 by welding, and a water outlet pipe 14 is fixedly provided on the water outlet chamber 12 by welding. Coolant enters the cooler body 1 from the water inlet pipe 13 on the water inlet chamber 11 and is discharged from the water outlet pipe 14 on the water outlet chamber 12 after cooling.

[0044] like Figure 3 , Figure 4 and Figure 8As shown, the all-aluminum radiator for automotive engines also includes: a first filter assembly, a second filter assembly, a linkage drive assembly, and a filter assembly locking mechanism. The first filter assembly is installed in the water inlet pipe 13 to filter the coolant entering the radiator body 1. The second filter assembly is installed on the first filter assembly and works in conjunction with it to filter the coolant. The cooperation between the first and second filter assemblies increases the range of filter holes through which the coolant can pass, effectively extending the service life and replacement cycle of both filters. The linkage drive assembly is installed in the water inlet chamber 11 and moves the first filter assembly, which in turn moves the second filter assembly, ensuring that both filters are in operation for filtration. The filter assembly locking mechanism is installed in the water inlet pipe 13 to lock the first filter assembly. This locking mechanism allows both the first and second filters to be stably installed on the radiator body 1, and facilitates easy installation and removal for replacement or cleaning during later use.

[0045] like Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10 As shown, the first filter assembly includes a filter support 2 and a first filter cylinder 3. The filter support 2 is inserted into the water inlet pipe 13. Specifically, in order to support the filter support 2 through the water inlet pipe 13, an inner ring platform 131 is integrally formed and fixed inside the water inlet pipe 13. A support protrusion ring 22 is integrally formed and fixed at one end of the filter support 2. When the filter support 2 is inserted into the water inlet pipe 13, the support protrusion ring 22 contacts the inner ring platform 131 in the water inlet pipe 13. In this way, the cooperation between the support protrusion ring 22 and the inner ring platform 131 can not only support the filter support 2, but also seal the gap between the filter support 2 and the water inlet pipe 13 through the tight cooperation between the support protrusion ring 22 and the inner ring 131, thus preventing coolant from entering the water inlet chamber 11 from the gap between the filter support 2 and the water inlet pipe 13.

[0046] The first filter cartridge 3 is movably mounted on the filter support cartridge 2, that is, symmetrical mating channels 23 are provided on the filter support cartridge 2, such as... Figure 8 and Figure 11As shown, a mating support plate 34 is symmetrically welded and fixed on the first filter cylinder 3 by welding process. The mating support plate 34 is inserted into the mating channel 23. The first filter cylinder 3 is installed on the filter support cylinder 2 by the mating support plate 34 and the mating channel 23. A support ring 37 is also welded and fixed on the end of the mating support plate 34 away from the first filter cylinder 3 by welding process. Positioning insertion holes 38 are symmetrically opened on the support ring 37. In addition, the first filter cylinder 3 is cylindrical, and filter holes for filtering coolant are opened on the bottom surface and the circumferential side surface of the first filter cylinder 3.

[0047] like Figure 10 As shown, the filter holder 2 has an installation cavity 21 inside. The first filter cylinder 3 is partially inserted into the filter holder 2 and is in close contact with the inner wall of the installation cavity 21. The inner wall of the installation cavity 21 is smooth and burr-free, which facilitates the movement of the first filter cylinder 3. The filter holder 2 and the first filter cylinder 3 cooperate to filter the coolant. When the first filter cylinder 3 filters the coolant, the filter holes on the first filter cylinder 3 are completely outside the installation cavity 21 and in the water inlet chamber 11, which increases the number of filter holes through which the coolant passes.

[0048] like Figure 8 , Figure 11 and Figure 12 As shown, the second filter assembly is a second filter cylinder 4, and there are two second filter cylinders 4, symmetrically installed on the first filter cylinder 3. To facilitate the installation of the second filter cylinders 4, insertion channels 31 are symmetrically opened on the first filter cylinder 3. The second filter cylinders 4 are inserted into the insertion channels 31, and the outer wall of the second filter cylinder 4 is in contact with the inner wall of the insertion channel 31 for a tight fit. Both the inner walls of the second filter cylinder 4 and the insertion channel 31 are smooth and burr-free, so that the movement of the second filter cylinder 4 relative to the first filter cylinder 3 will not be hindered. To further support and limit the movement of the second filter cylinders 4, the first filter cylinder 3 has... A support rod 35 is welded and fixed to the mating support plate 34 on the cylinder 3. A limiting support plate 36 is welded and fixed to the support rod 35. A support plate frame 43 is welded and fixed to the second filter cylinder 4. A support movable hole 44 is opened on the end of the support plate frame 43 away from the second filter cylinder 4. The support rod 35 is inserted into the support movable hole 44. The inner wall of the support movable hole 44 and the surface of the support rod 35 are both smooth and burr-free. The diameter of the support movable hole 44 matches the diameter of the support rod 35. The second filter cylinder 4 is supported and limited by the cooperation between the support rod 35 and the support movable hole 44.

[0049] In addition, in order to enable the second filter cartridge 4 to automatically reset smoothly when the first filter cartridge 3 is disassembled, a first spring 45 is also sleeved on the support rod 35. The two ends of the first spring 45 are respectively welded and fixed to the limiting support plate 36 and the support plate frame 43 on the second filter cartridge 4.

[0050] like Figure 12 As shown, filter holes for coolant to pass through are also provided on the surface of the second filter cylinder 4. When the second filter cylinder 4 filters the coolant, the filter holes on the second filter cylinder 4 are all outside the first filter hole 3. The second filter cylinder 4 and the first filter cylinder 3 work together to filter the coolant. When the filter holes on the second filter cylinder 4 are all outside the first filter cylinder 3, the number of filter holes that can allow coolant to pass through can be further increased, and the efficiency of coolant passage can be further improved. When more filter holes allow coolant to pass through, the first filter cylinder 3 and the second filter cylinder 4 are less likely to become clogged, which can effectively increase the service life of the first filter cylinder 3 and the second filter cylinder 4.

[0051] like Figure 3 , Figure 5 , Figure 13 and Figure 14 As shown, the linkage drive assembly includes a movable mating block 5 and a linkage support block 54. The movable mating block 5 is movably installed in the water inlet chamber 11. Specifically, an indoor boss 15 is welded and fixed in the water inlet chamber 11 by welding. Indoor support rods 16 are symmetrically welded and fixed at both ends of the indoor boss 15. A rectangular support column 17 is also welded and fixed on the indoor boss 15. The rectangular support column 17 is partially located in the water inlet pipe 13. In addition, the surface of the rectangular support column 17 is smooth and burr-free. A second rectangular through hole 51 is opened on the movable mating block 5. The inner wall of the second rectangular through hole 51 is smooth and burr-free. The rectangular support column 17 is inserted into the second rectangular through hole 51. The inner wall of the second rectangular through hole 51 is in contact with the rectangular support column 17. The cooperation between the second rectangular through hole 51 and the rectangular support column 17 plays a supporting and guiding role for the movable mating block 5, so that the movable mating block 5 can only move along the rectangular support column 17.

[0052] The linkage support block 54 consists of two blocks that are movably connected to the movable mating block 5. Specifically, the movable mating block 5 has two symmetrically hinged linkage mating rods 53 at both ends, and the other end of the linkage mating rod 53 is hinged to the linkage support block 54.

[0053] like Figure 11 and Figure 13As shown, the movable mating block 5 cooperates with the first filter cylinder 3. The first filter cylinder 3 drives the movable mating block 5 to move. Specifically, a rectangular sleeve 32 is welded and fixed to the outer end face of the first filter cylinder 3. A first rectangular through hole 33 is opened on the bottom surface of the first filter cylinder 3. The first rectangular through hole 33 and the rectangular sleeve 32 are interconnected, and the inner walls of both are smooth and burr-free. When installing the filter support cylinder 2, the rectangular support column 17 is inserted into the first rectangular through hole 33 and the rectangular sleeve 32, and the rectangular support column 17 is in close contact with the inner walls of the first rectangular through hole 33 and the rectangular sleeve 32. In addition, the rectangular sleeve 32 is in contact with the movable mating block 5. In this way, when the first filter cylinder 3 moves, the movable mating block 5 can be moved under the action of the rectangular sleeve 32.

[0054] In addition, in order to achieve the smooth reset of the movable mating block 5, a second spring 52 is also sleeved on the rectangular support column 17. The two ends of the second spring 52 are welded and fixed to the indoor boss 15 and the movable mating block 5, respectively. When the first filter cylinder 3 moves the movable mating block 5, the second spring 52 will be in a compressed state. In this way, when the first filter cylinder 3 is disassembled, the movable mating block 5 can be reset under the action of the second spring 52.

[0055] like Figure 5 and Figure 14 As shown, when the movable mating block 5 moves, it drives the linkage bearing block 54 to move. Specifically, a mating bearing strip 55 is integrally formed and fixed on the linkage bearing block 54. A movable bearing hole 56 is opened on the mating bearing strip 55. The inner wall of the movable bearing hole 56 is smooth and burr-free, and an indoor bearing rod 16 is inserted into the movable bearing hole 56. The surface of the indoor bearing rod 16 is also smooth and burr-free. The linkage bearing block 54 is supported and limited by the cooperation between the movable bearing hole 56 and the indoor bearing rod 16, so that the linkage bearing block 54 can only move along the indoor bearing rod 16. When the movable mating block 5 moves, it can drive the linkage mating rod 53 to swing, and then the linkage bearing block 54 can be moved under the action of the linkage mating rod 53.

[0056] like Figure 8 and Figure 14As shown, the linkage support block 54 cooperates with the second filter cylinder 4, and the linkage support block 54 drives the second filter cylinder 4 to move. Specifically, a linkage strip plate 57 is symmetrically welded and fixed on the cooperating support strip 55 by welding process. The surface of the linkage strip plate 57 is smooth and burr-free. A cylinder protrusion 41 is symmetrically and integrally formed and fixed on the second filter cylinder 4. A linkage channel 42 is opened on the cylinder protrusion 41. The inner wall of the linkage channel 42 is smooth and burr-free. When the filter cylinder 2 is inserted into the water inlet pipe 13, the linkage strip plate 57 will be inserted into the linkage channel 42 and the linkage strip plate 57 will contact the inner wall of the linkage channel 42. In this way, with the cooperation of the linkage strip plate 57 and the linkage channel 42, when the linkage support block 54 moves, it can drive the second filter cylinder 4 to move.

[0057] like Figure 6 As shown, a limiting channel 171 is provided at the end of the rectangular support column 17. The inner wall of the limiting channel 171 is smooth and burr-free. A mating plate 172 is integrally formed and fixed at the limiting channel 171, and an insertion interface 173 is formed between the mating plates 172.

[0058] like Figure 4 , Figure 7 and Figure 8 As shown, the filter assembly locking mechanism includes: a mounting lock bar 6 and a movable locking rod 63. The mounting lock bar 6 is inserted into the water inlet pipe 13, and a third rectangular through hole 61 is provided in the middle position of the mounting lock bar 6. The inner wall of the third rectangular through hole 61 is smooth and burr-free, and a rectangular support column 17 is inserted into the third rectangular through hole 61. The inner wall of the third rectangular through hole 61 is in contact with the rectangular support column 17.

[0059] Two movable locking rods 63 are symmetrically installed on the mounting lock bar 6. Specifically, to facilitate the installation of the movable locking rods 63, movable through holes 62 are symmetrically opened on the mounting lock bar 6. The movable through holes 62 are connected to the third rectangular through hole 61. The movable locking rods 63 are inserted into the movable through holes 62. One end of the movable locking rod 63 is welded to a connecting support plate 64. An elastic connecting strip 65 is welded to the connecting support plate 64. The other end of the elastic connecting strip 65 is welded to the mounting lock bar 6. In addition, the other end of the movable locking rod 63 is also welded to a positioning plate 66. A protruding connecting plate 67 is integrally formed and fixed on the positioning plate 66, and the positioning plate 66 and the protruding connecting plate 67 form a T-shape.

[0060] When the first filter cylinder 3 is locked by the movable locking rod 63, the movable locking rod 63 is inserted into the positioning hole 38 on the support ring 37. The first filter cylinder 3 is locked by the cooperation of the movable locking rod 63 and the positioning hole 38. At this time, the positioning plate 66 is stuck at the mating plate 172, realizing the fixed connection between the mounting lock bar 6 and the rectangular support column 17. In addition, at this time, the support ring 37 is pressed on the filter support cylinder 2, so the filter support cylinder 2 can be locked by the first filter cylinder 3.

[0061] During the installation of the filter support 2, it is inserted into the water inlet pipe 13. At the same time, the rectangular sleeve 32 and the first rectangular through hole 33 on the first filter cylinder 3 are fitted onto the rectangular support column 17. Simultaneously, the linkage plate 57 is inserted into the linkage channel 42 on the second filter cylinder 4, and the rectangular sleeve 32 on the first filter cylinder 3 is in contact with the movable mating block 5. At this time, the support protrusion ring 22 on the filter support 2 is in contact with the inner ring platform 131 in the water inlet pipe 13. During the process of inserting the filter support 2 into the water inlet pipe 13, the second filter cylinder 4 is mostly inserted into the first filter cylinder 3. This ensures that the first filter cylinder 3 can smoothly pass through the water inlet pipe 13 and enter the water inlet chamber 11. After the filter support 2 is inserted, the support ring 37 is pushed to contact the support protrusion ring 22.

[0062] As the support ring 37 moves, the first filter cylinder 3 will also move along with it. With the movement of the first filter cylinder 3, the filter holes on the first filter cylinder 3 will all be located outside the mounting cavity 21, so that the filter holes on the first filter cylinder 3 can be used to filter the coolant. As the first filter cylinder 3 moves, it will push the movable mating block 5 to move towards the inner boss 15, thereby compressing the second spring 52. At the same time, as the movable mating block 5 moves, under the action of the linkage mating rod 53, it will push the linkage bearing block 54 to move in opposite directions. As the linkage bearing block 54 moves, under the action of the linkage strip 57, it will drive the second filter cylinder 4 to move synchronously, thereby moving the second filter cylinder 4 to the outside of the first filter cylinder 3, so that the filter holes on the second filter cylinder 4 are also located outside the first filter cylinder 3.

[0063] This increases the number of filter holes used for filtering coolant, allowing coolant to pass through more filter holes, reducing the filtration pressure of the filter holes, making the filter holes less prone to clogging, and also allowing the first filter cartridge 3 and the second filter cartridge 4 to be used for a longer period of time.

[0064] Compared to the combination of the filter screen and the inlet pipe 13, the combination of the first filter cylinder 3 and the second filter cylinder 4 results in a higher coolant throughput and a larger volume. As the second filter cylinder 4 moves, the first spring 45 is stretched, simultaneously pulling the two protruding connecting plates 67 in opposite directions, compressing the elastic connecting strip 65. Then, the mounting lock strip 6 is fitted onto the rectangular support column 17. During this fitting process, the positioning plate 66 enters the limiting channel 171 from the insertion interface 173 until it contacts the bottom wall of the limiting channel 171. At this point, the fitting of the mounting lock strip 6 is complete. After fitting the mounting lock strip 6, the protruding connecting plates 67 are released one by one. With the release of the protruding connecting plates 67, the elastic connecting strip 65 causes the movable locking rod 63 to move in the opposite direction and reset. At this time, the movable locking rod 63 is aligned with the positioning insertion hole 38 on the support ring 37. Thus, as the movable locking rod 63 resets, it... The movable locking rod 63 is inserted into the positioning hole 38 on the support ring 37, which also causes the positioning plate 66 to be locked in the mating plate 172. In this way, the positioning plate 66 and the mating plate 172 cooperate to achieve a fixed connection between the installation locking bar 6 and the rectangular support column 17. At the same time, the movable locking rod 63 and the positioning hole 38 cooperate to fix the first filter cylinder 3. At this time, the support ring 37 is pressed on the support protrusion ring 22, and the support protrusion ring 22 is in contact with the inner ring platform 131 in the water inlet pipe 13, so it can also fix the filter support cylinder 2. The operation is simple, convenient and quick. When it is necessary to disassemble the filter support cylinder 2, pull the protruding connecting plate 67 again to make the movable locking rod 63 exit the positioning hole 38 to unlock the first filter cylinder 3 and the filter support cylinder 2. The movable mating block 5 is reset under the action of the second spring 52, which will also drive the second filter cylinder 4 to reset, so that the filter support cylinder 2 can be smoothly removed from the water inlet pipe 13.
