Description

Technical Field

[0001] The utility model relates to the field of water cooling radiators, in particular to a water cooling radiator structure with an integrated structure. Background Art

[0002] A computer water cooling system refers to a physical circulation system that uses the large specific heat capacity of water to dissipate heat from heat-prone modules such as the central processing unit and graphics card in a relatively closed computer host.

[0003] In order to integrate the water pump and the heat dissipation device, the existing water-cooling radiator structure generally makes the water pump protruding (hence the poor symmetry), so that the shell can accommodate a larger water pump and of course a smaller motor. However, in order to achieve heat dissipation, the water pipe stroke is generally longer, which may affect the heat dissipation efficiency.

[0004] For example, Chinese patent CN202321827770.4 has obvious protrusions (there is a problem of symmetry), which enables the circulation of fluids, and its waterway design is also relatively complex, and its adaptability and adjustability are poor. In actual factory production, molds need to be customized one by one according to demand to achieve the predetermined fluid circulation;

[0005] Of course, there are also horizontally raised shell structures (there is a problem of symmetry), such as Chinese patent CN202111026370.9, which realizes the integration of water channels of the water tank and the water pump. However, from a design point of view, it still has problems with aesthetics and inconvenient assembly, that is, the various structures cannot be assembled as separate modules. Utility Model Content

[0006] The main purpose of the utility model is to propose an integrated water-cooling radiator structure, which aims to change the existing water-cooling radiator structure and thereby realize the modularization of each structure, and its flow channel can be adjusted according to actual needs, and the direction of the fluid can be adjusted or changed according to actual needs.

[0007] In order to achieve the above-mentioned purpose, the utility model proposes an integrated water cooling row structure, comprising:

[0008] A shell, the shell comprising a front shell and a rear shell, the front shell and the rear shell enclose a hollow cavity, the hollow cavity is provided with a partition, and the hollow cavity is divided into a first pump cavity and a second pump cavity which are independent of each other, the upper wall of the first pump cavity is provided with a first water inlet, the rear wall of the first pump cavity is provided with a first water outlet, the rear wall of the second pump cavity is provided with a second water inlet, and the upper wall of the second pump cavity is provided with a second water outlet;

[0009] Water pumps, there are two water pumps, including a first water pump and a second water pump respectively arranged in a first pump chamber and a second pump chamber. The first water pump and the second water pump have the same structure. The front shell extends towards the rear shell with a limiting shell. The limiting shell is recessed in a hollow cavity. The inner wall of the limiting shell and the inner wall of the front shell enclose a pivoting interval. The outer peripheral wall of the limiting shell is provided with a limiting interval coaxially arranged with the pivoting interval;

[0010] There is an impeller between the inner wall of the limiting shell and the inner wall of the rear shell. The impeller is provided with a rotor structure extending into the pivoting interval; The limiting interval is provided with a magnetic induction coil cooperating with the rotor structure. When the magnetic induction coil is energized, it can drive the impeller to rotate;

[0011] A water cooling device, the water cooling device includes a front baffle and a rear baffle arranged at intervals, heat dissipation fins arranged between the front baffle and the rear baffle, and a heat dissipation water pipe. There are a plurality of heat dissipation fins arranged at intervals. The water pipe is arranged between two heat dissipation fins,

[0012] A first diversion channel is formed between the front baffle and the rear shell. The rear baffle is provided with a second diversion channel. The first diversion channel is provided with a water cooling inlet and a water cooling outlet,

[0013] The water cooling inlet is connected to the first water outlet, and the water cooling outlet is connected to the second water inlet,

[0014] The first diversion channel and the second diversion channel are used to connect the water pipes and enclose a circulation flow path. The two ends of the circulation flow path are the water cooling inlet and the water cooling outlet.

[0015] In this design, the water cooling row is set as two parts, its water pump module and water cooling device module. First, through the structure of the double water pumps, the fluid flow rate in the circulation flow path can be effectively increased, and then the flow rate stability of the fluid can be improved. In actual control, therefore, this design can realize the simultaneous heat dissipation of multiple heating elements, and the fluid flow rate is relatively stable;

[0016] At the same time, the hollow cavity makes the first pump chamber and the second pump chamber independent through the setting of the partition. It not only facilitates the driving of the impeller, but also serves as an independent water tank, avoiding the problem of interrupted flow when the water tank is opened, and effectively improving the fluid flow stability;

[0017] And through the setting of the limiting shell, a staggered structure is formed, and then the impeller is placed inside the hollow cavity. Therefore, its sealing performance is better, and there is no need to set a through shaft. At the same time, through the setting of the limiting interval and the pivoting interval, the cooperation between the rotor structure and the magnetic induction coil is realized, that is, the structure of the brushless motor. Its structure is simple, the assembly process is less, and the stability is better.

[0018] Of course, specific card slots will be provided between the front shell and the rear shell to install the sealing ring or to make the cavities independent of each other. Also, card slots and sealing rings will be provided between the rear shell and the front baffle to ensure the sealing of the first diversion channel. Of course, the diversion plate can also be provided with corresponding insertion structures or elastic pad structures. For example, a plastic-encapsulated structure can be provided on the diversion plate. Of course, existing technologies can also be adopted to achieve relative sealing. Description of the Drawings

[0043] As Figures 1 to 11 shown, a water cooling row structure of an integrated structure includes:

[0044] A housing 1, said housing 1 comprising a front shell 11 and a rear shell 12, the front shell 11 and the rear shell 12 enclosing a hollow cavity, a partition 7 being provided in the hollow cavity and dividing the hollow cavity into an independent first pump chamber 71 and a second pump chamber 72. The upper wall of the first pump chamber 71 is provided with a first water inlet 711, the rear wall of the first pump chamber 71 is provided with a first water outlet 712, the rear wall of the second pump chamber 72 is provided with a second water inlet 721, and the upper wall of the second pump chamber 72 is provided with a second water outlet 722;

[0045] Two water pumps, including a first water pump and a second water pump respectively disposed in the first pump chamber 71 and the second pump chamber 72. The first water pump and the second water pump have the same structure. The front shell 11 extends in the direction of the rear shell 12 with a limiting shell 2. The limiting shell 2 is recessed in the hollow cavity. The inner wall of the limiting shell 2 and the inner wall of the front shell 11 enclose a pivoting interval 201, and the outer peripheral wall of the limiting shell 2 is provided with a limiting interval 202 coaxially arranged with the pivoting interval 201;

[0046] An impeller 3 is provided between the inner wall of the limiting shell 2 and the inner wall of the rear shell 12. The impeller 3 is provided with a rotor structure 31 extending into the pivoting interval 201; a magnetic induction coil 32 is provided in the limiting interval 202 and is matched with the rotor structure 31. When the magnetic induction coil 32 is energized, the impeller 3 can be driven to rotate;

[0047] A water cooling device 8, said water cooling device 8 including a front baffle 81 and a rear baffle 82 arranged at intervals, heat dissipation fins 83 provided between the front baffle 81 and the rear baffle 82, and a heat dissipation water pipe 84. A plurality of the heat dissipation fins 83 are arranged at intervals, and the water pipe is arranged between two heat dissipation fins 83,

[0048] A first diversion channel 85 is formed between the front baffle 81 and the rear shell 12. The rear baffle 82 is provided with a second diversion channel 86. The first diversion channel 85 is provided with a water cooling inlet 87 and a water cooling outlet 88,

[0049] The water cooling inlet 87 is connected to the first water outlet 712, and the water cooling outlet 88 is connected to the second water inlet 721,

[0050] The first diversion channel 85 and the second diversion channel 86 are used to connect the water pipes and enclose a circulation channel, and the two ends of the circulation channel are the water cooling inlet 87 and the water cooling outlet 88.

[0051] In this design, the water cooling row is set as two parts, namely the water pump module and the water cooling device 8 module. First, through the structure of the double water pumps, the fluid flow rate of the circulation channel can be effectively increased, and then the flow rate stability of the fluid can be improved. In actual control, therefore, this design can realize the simultaneous heat dissipation of multiple heating elements, and the fluid flow rate is relatively stable;

[0052] Meanwhile, the hollow cavity is made independent of the first pump chamber 71 and the second pump chamber 72 respectively through the arrangement of the partition plate 7. This not only facilitates the driving of the impeller 3, but also serves as an independent water tank, avoiding the problem of interrupted flow when the water tank is opened, and effectively improving the flow stability of the fluid.

[0053] Moreover, through the arrangement of the limiting shell 2, a dislocation structure is formed, and the impeller 3 is placed inside the hollow cavity. Therefore, its sealing performance is better, and there is no need to set a penetrating rotating shaft 51. Meanwhile, through the arrangement of the limiting section 202 and the pivoting section 201, the cooperation of the rotor structure 31 and the magnetic induction coil 32 (i.e., the structure of the brushless motor) is realized. Its structure is simple, with fewer assembly processes and better stability.

[0054] Of course, specifically, a clamping groove will be set between the front shell 11 and the rear shell 12 to install a sealing ring or to make the cavities independent of each other. There will also be a clamping groove and a sealing ring installed between the rear shell 12 and the front baffle 81 to ensure the sealing performance of the first diversion channel 85. Of course, the diversion plate can also be provided with a relative insertion structure or an elastic pad structure. For example, a rubber-coated structure is set on the diversion plate. Of course, existing technologies can also be adopted to achieve relative sealing.

[0055] Specifically, a concave limiting groove 93 is provided on the rear wall of the front shell 11, and the rear shell 12 is installed in the limiting groove. A positioning cavity 91 is provided on the rear wall of the rear shell 12, and the positioning cavity 91 and the front baffle 81 enclose the first diversion channel 85. Adopting this structure can effectively reduce the thickness of the shell 1, and thus effectively reduce the thickness of the water-cooled radiator.

[0056] In the first embodiment of the present invention, when the front baffle 81 and the rear baffle 82 are respectively provided with diversion plates 200 arranged at intervals in the width direction, the circulating flow channel encloses a meandering one-way circulating channel.

[0057] In the second embodiment of the present invention, when the front baffle 81 and the rear baffle 82 are respectively provided with diversion plates arranged in the height direction, the circulating flow channel is composed of a plurality of spaced heat-dissipating water pipes 84 as the water inlet pipe and a plurality of spaced heat-dissipating water pipes 84 as the water outlet pipe. Among them, a meandering one-way circulating channel is preferably adopted, which has a simple and stable structure, a longer flow path, and can effectively achieve heat exchange.

[0058] Specifically, the limiting shell 2 includes a first bending part 21 extending from the front shell 11 towards the rear shell 12 and a bottom shell 23 extending from the end of the first bending part 21. The first bending part 21 and the bottom shell 23 enclose the limiting section 202, and the first bending part 21 and the front shell 11 enclose the pivoting section 201. Through the arrangement of the first bending part 21 and the bottom shell 23, the coaxial setting of the rotor structure 31 and the magnetic induction coil 32 is realized, and thus the rotation of the impeller 3 is realized.

[0059] Further, the bottom shell 23 is provided with a second bending portion extending outward, an inner wall of the second bending portion encloses a first pivot groove 41, a second pivot groove 42 matching with the first pivot groove 41 is provided at a position of the rear shell 12 opposite to the first pivot groove 41, a rotating shaft 51 is provided in the middle of the impeller 3, and two ends of the rotating shaft 51 are pivotally installed in the first pivot groove 41 and the second pivot groove 42. Through the setting of double fulcrums, the rotation stability and service life of the impeller 3 can be effectively improved. The existing one has a single fulcrum, so the service life is relatively short.

[0060] Specifically, the rotating shaft 51 is a ceramic rotating shaft 51.

[0061] More specifically, a graphite bearing 52 is provided between the rotating shaft 51 and the impeller 3, and the graphite bearing 52 is in a strip-shaped structure. Thereby, the friction during the rotation of the impeller 3 is effectively reduced, and at the same time, the ceramic rotating shaft 51 and the graphite bearing 52 have the function of preventing rust.

[0062] In the embodiment of the present utility model, the impeller 3 is provided with a shaft portion 30 extending into the first pivot groove 41, thereby providing a larger supporting area and improving the rotation stability of the impeller 3.

[0063] Further, the second bending portion protrudes into the limiting interval 202. The preferred solution is that the length of the first pivot groove 41 enclosed by the second bending portion extending in is greater than one-half of the length of the rotor structure 31, thereby ensuring the rotation balance of the impeller 3;

[0064] An arc-shaped blocking portion is further provided on the outer periphery of the impeller 3, and the arc-shaped blocking portion is provided with a notch. Through the setting of the arc-shaped blocking portion and the notch, the fluid pressure during the rotation of the fan blade 33 can be effectively increased, and thereby the flow velocity stability is improved.

[0065] In the embodiment of the present utility model, an arc-shaped fan blade 33 is provided on the rear wall or the peripheral wall of the impeller 3, and the fan blades 33 are arranged at intervals along the outer periphery of the impeller 3. Thereby, a predetermined fluid driving effect is achieved. The structure is simple and stable, and through the structure of the long rotating shaft 51 and the double fulcrums, a higher rotation speed can be realized, and thereby a greater fluid driving force can be effectively improved.

[0066] Specifically, the rotor structure 31 includes a fixed magnet and a plastic layer integrally coating the fixed magnet, and the plastic layer and the impeller 3 are integrally formed. Of course, in a specific embodiment, the fixed magnet can also be installed in an embedded structure, but by using the integrally coating plastic layer, it can effectively ensure that the rotor structure 31 does not contact the fluid, and thereby the service life of the rotor structure 31 is improved.

[0067] In the embodiment of the present utility model, the fluid inlet or the fluid outlet is arranged at the side wall position of the hollow cavity. The impeller 3 is further provided with an axially penetrating through hole 34, and the through hole 34 is arranged between two blades. The outer wall of the front housing 11 is provided with a PCB board 6, and the magnetic induction coil 32 is installed on the PCB board 6. The fluid can also be driven through the fluid. For example, a fluid outlet is arranged at the rear housing 12 or the fluid inlet is arranged at the position of the rear housing 12. At the same time, through the integrally arranged PCB board 6 and the magnetic induction coil 32, during installation, the PCB board 6 can be directly installed at the position of the first bending part 21.

[0068] It further includes a water cooling head 92, and the water cooling head 92 is respectively connected to the first water inlet 711 and the second water outlet 722, thereby realizing the heat exchange of the fluid.

[0069] For the first embodiment of the circulation flow channel, by arranging partition plates at intervals in the first diversion channel and the second diversion channel, adjacent water pipes are connected in series in sequence, thereby forming a circulation water channel.

[0070] For the first embodiment of the circulation flow channel, through the arrangement of the partition plates, multiple water pipes located in the middle position are used as the water inlet channels, and the water pipes on both sides are used as the water outlet channels, thereby forming two water outlet channels.

[0071] For the third embodiment of the circulation flow channel, through the arrangement of the partition plates, multiple water pipes on the right side are used as the water inlet channels, and multiple water pipes on the left side are used as the water outlet channels, thereby forming a circulation water channel.

[0072] In the present invention, the directions of water inlet and water outlet can also be interchanged, and a predetermined technical effect can also be achieved, not limited to the name.

[0073] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present utility model.
