Description

Technical Field

[0001] This invention relates to the field of radiator technology, specifically to an integrated water-cooled radiator. Background Technology

[0002] Currently, computer users have increasingly higher demands for computer graphics performance, which leads to greater heat generation in graphics cards. The graphics processing unit (GPU) is the component in a graphics card that generates the most heat. To enhance the heat dissipation performance of graphics cards, the use of water cooling radiators to cool the GPU has become a trend.

[0003] A water-cooled radiator includes a water block, a radiator, and water pipes. The two ends of the water pipes are connected to the water block and the radiator, respectively. The water block is in contact with the graphics processor in the graphics card. After the water block absorbs the heat generated by the graphics processor, it is conducted to the coolant in the water block. The water pump in the water block drives the coolant to circulate between the water block and the radiator. When the high-temperature coolant flows through the radiator, the heat is dissipated into the air, and it becomes low-temperature coolant and flows back to the water block, thus completing the heat dissipation of the graphics processor.

[0004] Using a water-cooling radiator to cool the graphics processor of a graphics card has the following disadvantages:

[0005] 1. Water cooling pipes are flexible pipes. The connection between the water cooling pipes and the water cooling head, as well as the connection between the water cooling pipes and the water cooling radiator, is prone to instability. At the same time, when the coolant is exposed to high temperature, or when the coolant reacts chemically with the water cooling radiator, gas will be generated, which will increase the pressure inside the water cooling radiator. This will make the water cooling pipes prone to rupture or detachment, which will easily cause the water cooling radiator to leak and damage the computer.

[0006] 2. High-performance graphics cards require a high-performance central processing unit (CPU) to achieve optimal performance. High-performance CPUs also generate a lot of heat, and users often use water cooling radiators to cool them. However, most computer cases only have one water cooling radiator installation position. If water cooling is used to cool both the CPU and the graphics processor at the same time, one of the water cooling radiators cannot be installed. Users need to modify the case or buy a case with at least two water cooling radiator installation positions, resulting in high costs and inconvenience for users. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated water cooling radiator, in which the water block and the water radiator are integrated, eliminating the need for water cooling pipe connections and not occupying the water radiator installation space in the chassis.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an integrated water-cooled radiator, comprising a water cooling head, an external water tank, and a water cooling radiator; the water cooling head includes a contact plate, a rotor assembly, and an electromagnetic coil, an inner water tank is formed inside the water cooling head, the contact plate is located on the bottom surface of the inner water tank, and the electromagnetic coil magnetically drives the rotor assembly to rotate in the inner water tank; the external water tank is connected to the inner water tank; the water cooling radiator includes a cold water drain tank and a flat tube assembly, and the cold water drain tank is connected to the external water tank through the flat tube assembly.

[0017] In the above technical solution, the integrated water-cooled radiator also includes a cooling fan for dissipating heat from the water-cooling radiator.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this type of integrated water-cooled radiator, the inner water tank, outer water tank, flat tube assembly, and cold water drain tank form a water-cooling liquid flow channel. The rotor assembly rotating in the inner water tank drives the water-cooling liquid to circulate in the water-cooling liquid flow channel, so that the water cooling head and water cooling radiator of this type of integrated water-cooled radiator are combined into one unit through the outer water tank. There is no need to install water cooling pipes between the water cooling head and water cooling radiator, avoiding the risk of leakage caused by water cooling pipe rupture or unstable connection.

When in use, it is more flexible than existing water cooling radiators and is also more aesthetically pleasing and simple. Attached Figure Description

[0036] 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.

[0037] Please see Figure 1 and Figure 2 An all-in-one water-cooling radiator used to cool the graphics processor of a graphics card.

[0038] This integrated water-cooled radiator includes a water block 1, an external water tank 2, and a water radiator 3.

[0039] Please see Figures 6-12The water cooling head 1 includes a contact plate 11, a base 12, an inner shell 14, a rotor assembly 13, and an electromagnetic coil 16.

[0040] The contact plate 11 is a metal plate with good thermal conductivity. In this embodiment, the contact plate 11 is a copper plate, and a square boss 112 is formed on the contact plate 11.

[0041] The base 12 is an engineering plastic workpiece with recesses on both sides. A cylindrical lower pivot seat 121 is formed in the middle of one side of the base 12, and the lower pivot seat 121 is integrally formed with the base 12. A guide hole 123 is provided on the side of the lower pivot seat 121. The guide hole 123 is a through hole that penetrates both sides of the base 12. In this embodiment, there are four guide holes 123, which are arranged circumferentially around the lower pivot seat 121. A guide plate 122 is provided on the bottom surface of the base 12. The guide plate 122 is an engineering plastic plate that is fastened to the bottom surface of the base 12.

[0042] The inner shell 14 is an engineering plastic shell, and its shape matches that of the base 12. A cavity is formed in the inner shell 14, and a cylindrical upper rotating bearing 141 is formed in the middle of the cavity. The upper rotating bearing 141 is integrally formed with the inner shell 14. Two connecting pipes 144 are provided on the main body of the inner shell 14. The connecting pipes 144 are cylindrical, and both connecting pipes 144 connect the cavity of the inner shell 14 to the outside of the inner shell 14.

[0043] The rotor assembly 13 includes an impeller 131 and a shaft 134. The shaft 134 is a cylindrical metal or ceramic shaft. The main body of the impeller 131 is a circular plate, with several blades 135 formed on one side. A cylindrical shaft housing 132 is formed on the main body of the impeller 131. The shaft 134 passes through the shaft housing 132 of the impeller 131, and both ends of the shaft 134 protrude from the shaft housing 132, thus forming the rotor assembly 13. The impeller 131 is made of a plastic-magnetic material, and the main body of the impeller 131 is magnetized, giving the impeller 131 itself magnetic properties, thereby enabling the impeller 131 to be magnetically coupled with the electromagnetic coil 16.

[0044] Furthermore, a bushing 136 is fitted onto the rotating shaft 134. The bushing 136 is a cylindrical ceramic bushing. The bushing 136 passes through the rotating shaft connector 132, and the rotating shaft 134 passes through the bushing 136. Both ends of the rotating shaft 134 protrude from the bushing 136. The bushing 136 is provided to improve the service life of the rotating shaft 134 and the impeller 131.

[0045] The contact plate 11 and the inner shell 14 are respectively fixed on both sides of the base 12. The bottom edge of the base 12 surrounds the protrusion 112 of the contact plate 11. The contact plate 11 is fixed to the bottom surface of the base 12 by screws, and the inner shell 14 is fixed to the top surface of the base 12 by screws. The internal space of the assembly consisting of the contact plate 11, the base 12 and the inner shell 14 forms the inner water tank 19, that is, the inner water tank 19 is formed inside the water cooling head 1. The contact plate 11 is located on the bottom surface of the inner water tank 19. The base 12 divides the inner water tank 19 into upper and lower parts. The guide hole 123 connects the two parts of the inner water tank 19. After the assembly is completed, the lower rotating shaft seat 121 and the upper rotating shaft seat 141 are both located in the inner water tank 19, and the lower rotating shaft seat 121 and the upper rotating shaft seat 141 are opposite each other and in a straight line. The connecting pipe 144 on the inner shell 14 connects the inside and outside of the inner water tank 19.

[0046] Furthermore, a guide ring 133 is formed on the impeller 131. The guide ring 133 is annular, and its outer radius is consistent with the main body radius of the impeller 131. The guide ring 133 is integrally formed with the impeller 131 and is located on both sides of the main body of the impeller 131 along with the blades 135. A guide groove 142 is formed in the inner housing 14. Specifically, the guide groove 142 is an annular groove formed inside the inner housing 14. The guide groove 142 matches the shape of the guide ring 133. The guide groove 142 is coaxial with the upper rotating shaft seat 141. At the same time, after the guide groove 142 and the upper rotating shaft seat 141 are formed, they both form protrusions on the outer side of the inner housing 14. The guide groove 142 and the upper rotating shaft seat 141 form an annular cavity between the two protrusions on the outer side of the inner housing 14. This annular cavity is called the coil groove 143.

[0047] The electromagnetic coil 16 magnetically drives the rotor assembly 13 to rotate within the inner water tank 19. Specifically, the electromagnetic coil 16 is housed in a coil slot 143, which is covered by a coil cover 17. The wires of the electromagnetic coil 16 pass through the coil cover 17 and are then led out. The rotor assembly 13 is housed within the inner water tank 19 between the inner housing 14 and the base 12. The two ends of the rotor shaft 134 of the rotor assembly 13 are inserted into the upper shaft seat 141 and the lower shaft seat 121, respectively. The guide ring 133 on the impeller 131 is located within the inner housing 14. After assembly, the rotating shaft 134 is located in the inner ring of the electromagnetic coil 16 in the guide groove 142, that is, the electromagnetic coil 16 surrounds the rotating shaft 134. When the electromagnetic coil 16 is energized, it generates a rotating magnetic field. The electromagnetic coil 16 is magnetically coupled to the impeller 131 through the rotating magnetic field. At this time, the impeller 131 of the rotor assembly 13 rotates in the inner water tank 19. The guide groove 142 and the guide ring 133 are used to guide the rotation of the rotor assembly 13, that is, the guide ring 133 rotates in the guide groove 142 to prevent the rotor assembly 13 from dislodging during rotation.

[0048] Furthermore, a heat-conducting plate 111 is provided on the boss portion 112 of the contact plate 11. The heat-conducting plates 111 are arranged parallel to each other on the boss portion 112. The heat-conducting plates 111 are integrally formed with the contact plate 11. The heat-conducting plates 111 are provided to increase the contact area between the contact plate 11 and the coolant in the inner water tank 19, thereby improving the heat transfer efficiency.

[0049] Furthermore, a first sealing ring 15 is provided between the contact plate 11 and the base 12, and a second sealing ring 10 is provided between the base 12 and the inner shell 14. The first sealing ring 15 and the second sealing ring 10 enhance the sealing degree between the contact plate 11, the base 12 and the inner shell 14.

[0050] The outer water tank 2 is a square metal box. Inside the outer water tank 2, a cylindrical collar 21 is formed. The collar 21 passes through the upper and lower surfaces of the outer water tank 2, and the interior of the collar 21 is not connected to the outer water tank 2. Two opposing sides of the outer water tank 2 are provided with side plates 23, which are embedded in the side surfaces of the outer water tank 2. Each side plate 23 has a row of elongated first flat tube holes 231. The bottom surface of the outer water tank 2 has two circular connecting holes 22.

[0051] Please see Figures 1-5 The water-cooled radiator 3 includes a cold water tank 31, a flat tube assembly, a fin assembly, an inner fastener 36, and an outer fastener 37.

[0052] The cold drainage tank 31 is a square aluminum alloy water tank with a liquid chamber inside. One side of the cold drainage tank 31 has a row of elongated second flat tube holes 311, and the side of the cold drainage tank 31 with the second flat tube holes 311 also has two elongated fastener slots 312, which are arranged on both sides of the row of second flat tube holes 311. In this embodiment, there are two cold drainage tanks 31. One of the cold drainage tanks 31 has a liquid injection port 313, which is sealed with screws.

[0053] The flat tube assembly includes a long flat tube 32 and a short flat tube 34. Both the long flat tube 32 and the short flat tube 34 are flat pipes made of aluminum alloy, meaning that both the long flat tube 32 and the short flat tube 34 contain liquid flow channels. The long flat tube 32 and the short flat tube 34 have the same cross-sectional shape, but different lengths, with the long flat tube 32 being longer than the short flat tube 34.

[0054] The long flat tube 32, the short flat tube 34, the first flat tube hole 231, and the second flat tube hole 311 are matched in shape; specifically, the cross-sectional shape of the long flat tube 32 and the short flat tube 34 is the same as the inner wall shape of the first flat tube hole 231 and the second flat tube hole 311, so that the long flat tube 32 and the short flat tube 34 can be inserted into the first flat tube hole 231 or the second flat tube hole 311.

[0055] The fin assembly includes long fins 33 and short fins 35; both long fins 33 and short fins 35 are aluminum alloy sheets with wavy folds. The wavy folds of long fins 33 and short fins 35 have the same shape, but the lengths of long fins 33 and short fins 35 are different, with long fins 33 being longer than short fins 35.

[0056] The inner fastener 36 is an aluminum alloy fastener, and the shape of its two ends matches the shape of the fastener groove 312 of the cold drainage tank 31, so that the two ends of the inner fastener 36 can be inserted into the fastener groove 312. In this embodiment, there are two inner fasteners 36. The outer fastener 37 is also an aluminum alloy fastener, and the length of the outer fastener 37 is longer than that of the inner fastener 36.

[0057] Two cold water tanks 31 are arranged on both sides of the outer water tank 2, which has side plates 23. The two cold water tanks 31 are connected to the outer water tank 2 through short flat pipes 34 in the flat pipe group. Specifically, all the short flat pipes 34 are arranged parallel to each other. One end of each short flat pipe 34 is inserted into the second flat pipe hole 311 of a cold water tank 31, and the other end is inserted into the first flat pipe hole 231 of the outer water tank 2. Each first flat pipe hole 231 is equipped with a corresponding short flat pipe 34, so that the cold water tank 31 and the outer water tank 2 are connected through the short flat pipes 34. There are two groups of short flat pipes 34, and each group of short flat pipes 34 connects a cold water tank 31 and the outer water tank 2.

[0058] Short fins 35 and short flat tubes 34 are arranged alternately. Specifically, a short fin 35 is sandwiched between each pair of adjacent short flat tubes 34, and heat exchange can be carried out between the short fins 35 and the short flat tubes 34. A short fin 35 is also provided on both sides of each group of short flat tubes 34.

[0059] The two cold water tanks 31 are also interconnected by long flat pipes 32. Specifically, all the long flat pipes 32 are arranged parallel to each other, and the long flat pipes 32 and the short flat pipes 34 are also parallel to each other. One end of each long flat pipe 32 is inserted into the second flat pipe hole 311 of one of the cold water tanks 31, and the other end is inserted into the second flat pipe hole 311 of the other cold water tank 31, so that the two cold water tanks 31 are interconnected by long flat pipes 32. There are two sets of long flat pipes 32, and the two sets of long flat pipes 32 are arranged on both sides of the outer water tank 2.

[0060] Long fins 33 and long flat tubes 32 are arranged alternately. Specifically, a long fin 33 is sandwiched between each pair of adjacent long flat tubes 32, and heat exchange can be carried out between the long fins 33 and the long flat tubes 32. A long fin 33 is also provided on the outside of each group of long flat tubes 32.

[0061] All long flat tubes 32 and short flat tubes 34 form a flat tube group, and all long fins 33 and short fins 35 form a fin group. The fin groups and flat tube groups are arranged alternately. After assembly, all long flat tubes 32 and short flat tubes 34 in the flat tube group can be connected through the cold water drainage box 31.

[0062] The inner water tank 19, the outer water tank 2, the long flat pipe 32, the short flat pipe 34, and the cold drainage tank 31 form a water cooling liquid flow channel.

[0063] The inner fasteners 36 fasten the fin assembly and the flat tube assembly and insert them into the fastener slots 312. Specifically, the two inner fasteners 36 press the fin assembly and the flat tube assembly from both sides, causing the fin assembly to undergo elastic deformation. Then, the two ends of the inner fasteners 36 are inserted into the fastener slots 312 of the two cold water tanks 31. The two outer fasteners 37 fasten the two inner fasteners 36 from the outside. The two ends of the outer fasteners 37 are fixed to the outer walls of the two cold water tanks 31 with screws, so that the inner fasteners 36, the fin assembly, the flat tube assembly, the outer water tank 2, and the two cold water tanks 31 are tightly connected and become a whole. After assembly, the outer water tank 2 and the water-cooled radiator 3 are passed through a welding furnace to weld the outer water tank 2 and the water-cooled radiator 3 into a whole.

[0064] The outer water tank 2 is fitted onto the inner shell 14 and communicates with the inner water tank 19. Specifically, the collar 21 of the outer water tank 2 is fitted onto the protrusion formed on the outer side of the guide groove 142 of the inner shell 14. The two connecting pipes 144 of the inner shell 14 are inserted into the two connecting holes 22 of the outer water tank 2, so that the outer water tank 2 communicates with the inner water tank 19.

[0065] Furthermore, the outer water tank 2 and the inner shell 14 are connected by a connecting plate 24, which is a square metal plate. A first circular hole 241 is provided in the middle of the connecting plate 24, and two second circular holes 242 are provided on both sides of the first circular hole 241. Both the first circular hole 241 and the second circular hole 242 penetrate the connecting plate 24. The radius of the first circular hole 241 is the same as the inner radius of the collar 21 of the outer water tank 2, and the radius of the second circular hole 242 is the same as the outer radius of the connecting pipe 144 of the inner shell 14. The first circular hole 241 of the connecting plate 24 is fitted onto the protrusion formed on the outside of the guide groove 142 of the inner shell 14, and the two second circular holes 242 are respectively fitted onto the two connecting pipes 144 of the inner shell 14. The outer water tank 2 is fixed to one side of the connecting plate 24 by screws, and the inner shell 14 is fixed to the other side of the connecting plate 24 by screws.

[0066] Furthermore, a third sealing ring 145 is fitted on the connecting pipe 144. After the connecting plate 24 is assembled, the inner shell 14 and the connecting plate 24 press against the third sealing ring 145 to improve the sealing degree between the inner shell 14 and the connecting plate 24.

[0067] After the integrated water-cooled radiator is assembled, unscrew the screw on the filling port 313 of the cold water tank 31 to add coolant into the integrated water-cooled radiator. The coolant flows sequentially through the cold water tank 31, the short flat tube 34, the long flat tube 32, the outer water tank 2, and the inner water tank 19 until the coolant flow channel is full. After the coolant flow channel is full of coolant, screw the screw into the filling port 313 to complete the filling operation of the integrated water-cooled radiator.

[0068] The base 12 of the water block 1 is equipped with a fastener 18. When in use, the integrated water cooler is fixed to the printed circuit board (PCB) of the graphics card by the fastener 18, so that the contact plate 11 contacts the graphics processor on the graphics card.

[0069] Please see Figure 13 and Figure 14 Furthermore, this all-in-one water cooler also includes a faceplate 4, a base plate 6, and cooling fans 5; the base plate 6 is a metal plate or an engineering plastic plate, with square holes on its bottom surface; the base plate 6 is fixed to the printed circuit board of the graphics card, and the water block 1 passes through the square holes of the base plate 6; the faceplate 4 is a cover made of engineering plastic, with two fan holes on its top surface, and the faceplate 4 is fixed to the base plate 6; the base plate 6 and the faceplate 4 cover the water radiator 3 to enhance the dustproof performance of the water radiator 3; there are two cooling fans 5, and the main bodies of the two cooling fans 5 are respectively fixed to the faceplate 4 with screws, and the positions of the cooling fans 5 and the two fan holes of the faceplate 4 are matched, that is, the fan blades of the cooling fans 5 rotate in the fan holes, and the cooling fans 5 are set to enhance the heat dissipation capacity of this all-in-one water cooler.

[0070] When this type of integrated water-cooled radiator is in use, the contact plate 11 absorbs the heat generated by the graphics processor of the graphics card. After the electromagnetic coil 16 is energized, the electromagnetic coil 16 is magnetically coupled to the impeller 131 of the rotor assembly 13, thereby driving the impeller 131 to rotate. The rotating impeller 131 drives the flow of coolant in the inner water tank 19, causing the coolant to flow between the inner water tank 19, the outer water tank 2, the short flat tube 34, the cold drain tank 31, and the long flat tube 32. When the coolant flows through the short flat tube 34 and the long flat tube 32, it exchanges heat with the short fins 35 and the long fins 33 in the fin assembly, respectively, thereby conducting heat to the fin assembly. The fin assembly dissipates the heat into the air. The airflow generated by the cooling fan 5 blows over the fin assembly, enhancing the air convection at the fin assembly, making it easier for the fin assembly to dissipate heat into the air.

[0071] In this type of integrated water-cooled radiator, the inner water tank 19, the outer water tank 2, the flat tube assembly, and the cold water drain tank 31 form a water-cooling liquid flow channel. The rotor assembly 13 rotating in the inner water tank 19 drives the water-cooling liquid to circulate in the water-cooling liquid flow channel, so that the water cooling head 1 and the water cooling radiator 3 of this type of integrated water-cooled radiator are combined into one unit through the outer water tank 2. There is no need to install water cooling pipes between the water cooling head 1 and the water cooling radiator 3, avoiding the risk of leakage caused by water cooling pipe rupture or unstable connection.

[0072] Meanwhile, the water block 1 of this integrated water cooling radiator can be directly mounted on the printed circuit board of the graphics card through the fastener 18. The water block 1 and the water radiator 3 are integrated, so the water radiator 3 will not occupy the water radiator installation position in the case.
