[0037] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0038] As introduced in the background technology, the existing vibration reduction structure is a U-shaped vibration reduction pad 3. In order to solve the problem of loss of vibration reduction effect caused by deformation of the bottom U-shaped vibration reduction pad 3 and movement of the vibration reduction pad, the utility model proposes a radiator vibration reduction structure.
[0039] like Figure 3 , Figure 4 , Figure 5 As shown, the heat sink includes a core 2 and a frame 1, wherein the core 2 is located inside the frame 1. Figure 6 As shown, the vibration reduction structure includes a sleeve 8, a shaft sleeve and a locking piece. The sleeve 8 is located in the frame 1 and passes through the core 2. A pair of sleeves 8 are installed at the upper and lower ends of the core 2. The sleeves 8 are combined into one with the water chamber of the core 2 by welding. Each core 2 adopts a 4-point fixed connection vibration reduction method.
[0040] like Figure 7 As shown, the sleeve includes a first sleeve 5 and a second sleeve 6, which are respectively plugged into the two ends of the sleeve 8, and both sleeves are provided with a vibration-damping sleeve, which is a rubber sleeve 51, and the outer layer of the sleeve is wrapped with a vibration-damping rubber layer. The length of the first sleeve 5 is shorter than the length of the second sleeve 6; the locking member is installed at both ends of the second sleeve 6, and the locking member connects the first sleeve 5 to the second sleeve 6, and the length of the locking member at one end of the first sleeve 5 is greater than the length of the locking member at one end of the second sleeve 6.
[0041] The vibration reduction structure of this embodiment is connected by the sleeve 8 and the sleeve, and a vibration reduction sleeve is arranged outside the sleeve to effectively absorb and buffer the external force and internal stress transmitted by the frame 1, so as to realize the vibration reduction combined structure of the radiator core 2. Therefore, no matter where the vibration reduction structure is located, it can play an equal vibration reduction role, and there will be no problem of the main force on the bottom, which prolongs the vibration reduction time. Moreover, the sleeve 8 passes through the core 2 and is installed on the frame 1, which avoids the displacement and separation of the vibration reduction structure and the core 2, and ensures the normal vibration reduction effect.
[0042] Two shaft sleeves of different lengths are installed at both ends of the sleeve 8 and connected. At the same time, the short shaft sleeve and the long locking piece are combined on one side of the radiator, and the long shaft sleeve and the short locking piece are combined on the other side of the radiator. This assembly method avoids the occurrence of resonance and improves the vibration reduction effect.
[0043] like Figure 5 As shown, the frame 1 includes a mounting hole 21, the sleeve 8 is installed in the mounting hole 21, and the vibration-damping sleeve is inserted in the sleeve 8. Fig.10 As shown, the first sleeve 5 includes a support sleeve 53, and the vibration-damping sleeve is sleeved on the support sleeve 53. Fig. 9 As shown, the second sleeve 6 includes a support rod 63, the vibration-damping sleeve is sleeved on the support rod 63, and the inner end surface of the support sleeve 53 abuts against the inner end surface of the support rod 63. The locking member includes a first locking member 4 and a second locking member 7, both of which are bolts, wherein the length of the first locking member 4 is greater than the length of the second locking member 7, the first locking member 4 installs the support sleeve 53 on the left end of the support rod 63, and presses the inner side surface of the left side of the frame 1 on the outer end surface of the support sleeve 53, and the second locking member 7 is installed on the right end of the support rod 63, and presses the inner side surface of the right side of the frame 1 on the end surface of the support rod 63. The distance between the outer end surface of the support sleeve 53 and the outer end surface of the support rod 63 is 0.1mm-0.3mm smaller than the distance between the inner sides of the frame 1. For example, the total length of the short sleeve + the long sleeve is "L", the width of the inner side of the frame 1 is "W", L-0.2 = W, and the installation of the sleeve is facilitated by the setting of 0.2mm. Moreover, after the bolts are used for assembly, the contact between the short sleeve and the long sleeve plays the role of bolt limiter, which can effectively reduce the extrusion (friction) of the bolts on the frame 1 and the vibration damping sleeve, release the assembly stress caused by the manufacturing deviation of the parts, and extend the service life of the parts.
[0044] like Fig. 9 As shown, both ends of the support rod 63 are provided with threaded holes, and the support rod 63 faces one end of the support sleeve 53 (i.e. Fig. 9 The left end of the middle part is the first threaded hole 61 for installing the first locking member 4, and the end of the support rod 63 away from the support sleeve 53 (i.e. Fig. 9The second threaded hole 62 at the middle right end is used to install the second locking member 7. The threaded holes at both ends of the support rod 63 are used to install and fix the locking members at both ends, and the structure is simple. The threaded holes at both ends of the long shaft sleeve can achieve coaxial vibration reduction and eliminate internal stress after the two sides of the radiator are assembled.
[0045] like Figure 8 , Fig.12 As shown, a positioning groove 81 is provided on the inner hole of the sleeve 8, and a convex strip 52 is provided on the outer wall of the vibration-damping sleeve, and the convex strip 52 on the vibration-damping sleeve is inserted into the positioning groove 81 of the sleeve 8. The cooperation between the convex strip 52 on the vibration-damping sleeve and the positioning groove 81 on the sleeve 8 prevents relative rotation and reduces wear under vibration conditions.
[0046] like Figure 7 , Figure 8 As shown, the convex strip 52 of the vibration-damping sleeve installed on the upper end of the core 2 faces upward, as shown in FIG. Fig.11 , Fig.12 As shown, the convex strip 52 of the vibration-damping sleeve installed at the lower end of the core body 2 faces downward. The positioning grooves 81 of the sleeve 8 are also installed in a back-to-back manner, which is convenient for distinguishing during installation.
[0047] Based on the above radiator vibration reduction structure, the embodiment of the utility model further provides a radiator assembly, including a frame 1, a core 2 and a radiator vibration reduction structure, wherein the vibration reduction structure mounts the core 2 on the frame 1. Since the above radiator vibration reduction structure has the above technical effects, the technical effects of the radiator assembly using the radiator vibration reduction structure can refer to the above embodiment.
[0048] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
