Abstract
Description
Technical Field
[0001] This application relates to the field of heat dissipation technology, and in particular to a water-cooled radiator with a shell structure. Background Technology
[0002] Current water-cooled radiators generally use rigid engineering plastics (such as acrylonitrile-butadiene-styrene copolymer ABS, polycarbonate PC) or metal materials (aluminum alloy / stainless steel) as the water pump housing. Traditional structures fix the water pump to the rigid housing cavity using screws or magnetic attachment. When the pump is operating, the mechanical vibration generated by the high-speed rotation of the rotor is transmitted to the housing through the fixing points, resulting in mechanical vibration and noise. This not only degrades the user experience but also poses a risk of screw loosening over time due to resonance. Therefore, there is an urgent need for a water-cooled radiator with a housing structure that incorporates vibration damping and noise reduction functions. Utility Model Content

Therefore, they should not be construed as limitations on this application.
[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can be fixed connections, detachable connections, mating connections or integral connections; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0026] Figure 1 This is a schematic diagram of a water-cooled radiator with a shell structure, provided as an embodiment of this application. Figure 1 As shown, the water-cooled radiator includes a water pump 21 and a housing 11. The housing 11 is mounted outside the water pump 21 and is at least partially made of an elastic material. The housing 11 absorbs the vibration and noise generated by the water pump 21 during operation through the elastic material.
[0027] Specifically, refer to Figure 1 The water pump 21 is a component of the water-cooled radiator, and its main function is to drive the coolant to circulate within the cooling system. The water pump 21 pumps the coolant from the water block to the radiator, and the water block can directly contact heat-generating components such as the CPU and GPU. During the circulation of the coolant, the high-speed rotation of the rotor of the water pump 21 generates mechanical vibration and noise, which is transmitted to the outer casing 11, thus causing mechanical vibration and noise to the casing 11.
[0028] Continue to refer to Figure 1 The housing 11 can be installed outside the water pump 21. At least a portion of the housing 11 can be made of an elastic material. During the operation of the water pump 21, the elastic material can be used to absorb the vibration generated by the water pump 21 and reduce the operating noise of the water pump 21.
[0029] As can be seen from this example, a housing 11 is provided outside the water pump 21. During the operation of the water pump 21, the housing 11 absorbs the vibration generated by the water pump 21 through the damping characteristics of its elastic material, and can reduce the operating noise of the water pump 21. This can improve the user experience and reduce the potential problems such as loose screws caused by the vibration of the water pump 21.
[0030] In one example, at least one damping element may be provided between the inner wall of the housing 11 and the water pump 21, and the inner wall of the housing 11 and the water pump 21 are connected by the damping element, which is made of an elastic material. The damping element can be used to reduce the vibration generated by the water pump 21.
[0031] Specifically, the damping element can be spiral, ring-shaped, block-shaped, sheet-shaped, etc. The connection method between the damping element and the inner wall of the housing 11 and the water pump 21 can be adhesive, clamping, or embedded connection. For example, the damping element can be glued to the housing or water pump using adhesive, or the damping element can be clamped together with the housing and water pump using screws or other fasteners. Alternatively, appropriate space can be reserved in the design of the housing or water pump to accommodate the damping element, allowing it to naturally embed itself within it. Of course, the damping element can also be manufactured integrally with the housing 11; this solution does not impose any restrictions on this.
[0032] As can be seen from this example, the damping element, through its elastic deformation, can absorb the mechanical vibration energy of the water pump 21, thereby reducing the vibration amplitude transmitted to the casing. Furthermore, the nonlinear stiffness characteristics of the damping material can alter the system's natural frequency, preventing resonance between the excitation frequency of the water pump 21 and the casing, thus preventing vibration amplification. Simultaneously, by reducing the vibration of the casing 11, the damping element can reduce the noise radiated into the air by the water pump 21. In addition, the instantaneous impact force generated when the water pump 21 starts, stops, or experiences sudden flow changes can be buffered by the elastic deformation of the damping element, thereby protecting the casing 11 structure from stress damage.
[0033] In one example, reference Figure 2 The inner wall surface 110 of the outer casing 11 is provided with a concave-convex structure 1101, which is made of elastic material and is used for shock absorption and noise reduction of the water pump 21. Specifically, the concave-convex structure 1101 can be... Figure 2 The honeycomb or corrugated pattern shown can also be circular or hemispherical protrusions, serrated, spring-like, etc., and this solution does not limit this. The surface texture formed by its concave-convex structure 1101 can effectively scatter sound waves and destroy the coherence of noise. At the same time, through the coupling with the shell, it further blocks the transmission path of vibration energy.
[0034] In this example, the concave-convex structure 1101 changes the contact surface between the water pump 21 and the housing 11 from a continuous plane to discrete protrusions or ridges, which can significantly reduce the effective area for vibration transmission, thereby reducing the transmitted vibration amplitude. The concave-convex structure 1101 also increases the relative motion resistance between the housing 11 and the water pump 21, playing a buffering and damping role. In addition, its irregular surface structure causes the incident sound waves to undergo multiple reflections and directional deflections, reducing the noise intensity directly radiated outward.
[0035] In one example, reference Figure 3The outer casing 11 can be composed of a first inner casing 111 and a first outer casing 112. Specifically, the first inner casing 111 can be nested inside the first outer casing 112, and the water pump 21 can be installed inside the first inner casing 111. At least a portion of the first inner casing 111 and the first outer casing 112 can be made of an elastic material, wherein, during the operation of the water pump 21, the elastic material can be used to absorb the vibration generated by the water pump 21 and reduce the operating noise of the water pump 21.
[0036] Specifically, at least a portion of the first inner shell 111 and the first outer shell 112 refers to the first inner shell 111, or the first outer shell 112, or at least a portion of the first inner shell 111, or at least a portion of the first outer shell 112, and this solution does not limit this.
[0037] As can be seen from the above example, the vibration generated by the water pump 21 can be absorbed by the elastic material, thereby reducing the operating noise of the water pump 21. Dividing the outer shell 11 into a first inner shell 111 and a first outer shell 112 allows the sound waves to be reflected and attenuated multiple times in the air layer or elastic layer between the inner and outer shells, thereby further reducing the operating noise of the water pump 21.
[0038] In one example, the inner wall of the first inner shell 111 and the water pump 21 may be provided with at least one damping element, and the inner wall of the outer shell 11 and the water pump 21 may be connected through the damping element, which is made of an elastic material. The damping element can be used to reduce the vibration generated by the water pump 21.
[0039] In one example, the inner wall surface of the first inner shell 111 is provided with a concave-convex structure 1101, which is used for vibration reduction and noise reduction of the water pump 21.
[0040] In another example, continue to refer to Figure 3 The outer wall surface of the first inner shell 111 may also be provided with a concave-convex structure 1101. Here, the outer wall surface of the first inner shell 111 refers to the contact surface between the first inner shell 111 and the first outer shell 112.
[0041] It is easy to understand that its concave-convex structure 1101 can increase the relative motion resistance between the first inner shell 111 and the first outer shell 112, playing a buffering and damping role. In addition, its irregular surface structure will further cause the incident sound wave to undergo multiple reflections and directional deflections, reducing the noise intensity directly radiated outward.
[0042] In one example, the first inner shell 111 may be made of an elastic material, and its first outer shell 112 may be made of rigid plastic.
[0043] In one example, the first inner shell 111 may be made of an elastic material, and its first outer shell 112 may also be made of an elastic material.
[0044] In one example, the first inner shell 111 may be made of rigid plastic, while its first outer shell 112 may be made of a flexible material.
[0045] In one example, reference Figure 4 The first inner shell 111 can be fixed to the inside of the first outer shell 112 by means of a snap-fit connection. For example, as... Figure 4 As shown, the first inner shell 111 can be fixed inside the first outer shell 112 by the inner shell buckle 1102 and the outer shell buckle 1103. Specifically, the inner shell buckle 1102 is a protruding end, and the outer shell buckle 1103 is a recessed end. The first inner shell 111 is fixed inside the first outer shell 112 by the cooperation of the protruding end and the recessed end.
[0046] In one example, continue to refer to Figure 4 The water pump 21 can be fixed inside the first inner housing 111 by means of a threaded connection. For example, as... Figure 4 As shown, the water pump 21 can be fixed inside the first inner shell 111 by screw 1104.
[0047] In another example, continue to refer to Figure 4 The first inner shell 111 can be fixed inside the first outer shell 112 by a snap-fit connection. Alternatively, the water pump 21 can be fixed inside the first inner shell 111 by a threaded connection. For example, as... Figure 4 As shown, the first inner shell 111 can be fixed inside the first outer shell 112 by the inner shell buckle 1102 and the outer shell buckle 1103, and the water pump 21 can be fixed inside the first inner shell 111 by the screw 1104.
[0048] In another example, the first inner shell 111, the first outer shell 112, and the water pump 21 can also be fixed by magnetic connection. For example, some components can be made of a strongly magnetic material, such as embedding magnets at the mating surfaces between the first inner shell 111, the first outer shell 112, and the water pump 21, using magnetic force for direct adsorption and fixation. Small magnets can also be installed on the contact surfaces of the first inner shell 111, the first outer shell 112, and the water pump 21, directly attracting the metal surfaces of the other components or another magnet through their own magnetic field strength. Ring magnets or magnetic strips can also be arranged at the mating edges between the first inner shell 111, the first outer shell 112, and the water pump 21, using slots or protrusions for positioning. For example, wedge-shaped or cylindrical protrusions can be designed at the edge of the first inner shell 111, and matching grooves can be opened at the edge of the first outer shell 112, embedding the protrusions into the slots. The magnetic force, along with the slots and protrusions, collectively resists lateral displacement or vibration.
[0049] In one example, reference Figure 5The first inner shell 111, the first outer shell 112, and the water pump 21 can be fixed by a magnet 1106 and a magnetic unit 1105. The first outer shell 112 is provided with a magnetic unit 1105, the first inner shell 111 is provided with an alignment hole 1107, and the water pump 21 is provided with a magnet 1106. The first outer shell 112, the first inner shell 111, and the water pump 21 are sequentially aligned through the alignment hole 1107. The magnetic attraction between the magnet 1106 and the magnetic unit 1105 forms a levitation connection structure between the first outer shell 112, the first inner shell 111, and the water pump 21.
[0050] It is easy to understand that the first outer shell 112 can be provided with a receiving hole for accommodating the magnetic unit 1105, or a magnet can be pre-embedded in the first outer shell 112 during the overmolding stage to form a magnetic attraction unit 1105. At the same time, a magnet 1106 with the same pole opposite to the water pump 21 is fixedly installed at the corresponding position. When the first outer shell 112, the first inner shell 111 and the water pump 21 are aligned in sequence according to the positioning hole 1107, the magnet 1106 and the magnetic unit 1105 generate magnetic attraction within the effective working distance, realizing the automatic alignment and assembly of the shells. Through the magnetic attraction, the first outer shell 112, the first inner shell 111 and the water pump 21 form a stable floating connection structure.
[0051] As can be seen from the above example, the opposite arrangement of the same poles of magnet 1106 and magnetic unit 1105 forms a controllable magnetic attraction force, maintaining a gap between the water pump 21 and the first outer shell 112 and the first inner shell 111, forming a non-direct contact suspension state. The mechanical vibrations generated by the water pump 21 during operation (such as motor eccentricity and impeller pulsation) cannot be directly transmitted to the outer shell through rigid structures (such as screws and clips), significantly reducing structural sound transmission and thus reducing noise transmission. The magnetic attraction force generates a reverse damping effect during dynamic vibration. When the water pump 21 vibrates and attempts to move the outer shell, the change in the magnetic field generates a counterforce against the vibration, thereby reducing the vibration caused by the water pump 21 to the outer shell.
[0052] Based on any of the above examples, the elastic materials include, but are not limited to: rubber, rubber composites, silicone, silicone composites, and thermoplastic elastomers. Rigid plastics include, but are not limited to: acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamide, polyoxymethylene, and polybutylene terephthalate.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
