[0007] The elastic arm section is constructed such that when the support bar is installed in place, it elastically abuts against the inner surface of the corresponding heat dissipation fin group facing the gap, thereby generating opposing elastic preload between the first heat dissipation fin group and the second heat dissipation fin group.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Dual-tower CPU coolers consist of two finned arrays, suitable for CPUs with high cooling requirements. However, their structural rigidity is insufficient: the finned arrays are primarily connected via heat pipes. This connection method makes the cooler prone to deformation during transportation, causing the tower to tilt or shift, thus affecting cooling performance. Furthermore, the high-frequency airflow from the fan may induce resonance in the finned arrays, leading to reduced cooling efficiency.

[0037] To address the shortcomings and problems of existing heat sinks, this disclosure provides a stability-enhanced dual-tower heat sink to solve the deformation and resonance issues of traditional dual-tower heat sinks. Specific embodiments and accompanying drawings are described below. Figure 1-4 The present invention will be further elaborated and explained.

[0038] This disclosure provides a dual-tower heat sink with enhanced stability, comprising: a first heat sink fin group 1 and a second heat sink fin group 2 disposed opposite to each other, with a gap 3 formed between the first heat sink fin group 1 and the second heat sink fin group 2 for accommodating a fan unit; a heat pipe group 4 passing through the two heat sink fin groups and fixedly connected to a heat sink base 5, the bottom of the heat sink base 5 being configured as a heat-conducting surface for contacting a heat source; and one or more support bars 6, each support bar 6 including a connecting portion 61 spanning the gap 3 and snap-fit ​​portions 62 at both ends of the connecting portion 61;

[0039] The snap-fit ​​part 62 includes an elastic arm section 621, which is configured to elastically abut against the inner surface of the corresponding heat dissipation fin group facing the gap 3 when the support bar 6 is installed in place, thereby generating opposing elastic pre-tightening forces between the first heat dissipation fin group 1 and the second heat dissipation fin group 2.

[0040] The fixed section 622 is configured to cooperate with the limiting structure provided on the corresponding heat dissipation fin group to limit the installation of the support bar 6 on the first heat dissipation fin group 1 and the second heat dissipation fin group 2.

[0041] The dual-tower radiator uses support bars 6 and elastic arm sections 621 to apply bidirectional preload to the heat dissipation fin groups on both sides to suppress the relative displacement of the towers, keeping the deformation of the gap between the two towers within 1mm. The support bars 6 are fixed and installed on the first heat dissipation fin group 1 and the second heat dissipation fin group 2 by cooperating with the limiting structure set on the corresponding heat dissipation fin group by the fixing section 622. This forms a stable support structure between the two heat dissipation fin groups, which helps to maintain the shape of the dual-tower radiator during transportation and reduces the amplitude of the dual towers when the fan starts and stops or when the fan rotates at high frequency, making it suitable for actual working conditions.

[0042] In one embodiment, the support bar can cooperate with several auxiliary support members, which are configured to fix the fan unit to the first heat sink fin group or the fan unit to the second heat sink fin group. The support bar and auxiliary support members work together to enhance the connection strength between the cooling fan and the heat sink fins, facilitating the stability of the heat sink structure. (Added according to the drawings)

[0043] In one embodiment, to rationalize and simplify the structure, the fixing section 622 is configured to cooperate with the limiting structure provided on the corresponding heat dissipation fin group, located at the outer edge of the side parallel to the air outlet direction or at the gap between adjacent heat dissipation fins, so as to limit the installation of the support bar 6 on the first heat dissipation fin group 1 and the second heat dissipation fin group 2.

[0044] In one embodiment, the fixed section 622 of the support bar 6 can also be installed on the heat sink fin assembly by means of fasteners, the fasteners being self-tapping screws, the heat sink fin assembly having limit through holes, the limit through holes being adapted to the fasteners, and the two ends of the support bar 6 being fixedly connected to the heat sink fin assembly by self-tapping screws.

[0045] In one embodiment, the fixing section 622 of the support bar 6 is a hook structure provided at both ends of the support bar 6. The outer edge of the side of the heat dissipation fin group parallel to the air outlet direction is provided with an inwardly recessed buckle 7. The hook structure cooperates with the buckle 7 so that both ends of the support bar 6 are respectively fixed on the two heat dissipation fin groups, thereby simplifying the limiting structure and facilitating quick installation.

[0046] In one embodiment, at least one protruding stop block 8 is provided on the outer edge of the side of the heat dissipation fin assembly, adjacent to the buckle 7. The stop block 8 is configured to block the support bar 6 from moving in a direction parallel to the heat dissipation fin plane and away from the heat dissipation fin when the hook structure is positioned and installed in the buckle 7. Thus, when the support bar 6 is subjected to lateral vibration, the hook is blocked from the path by the stop block 8 and is held in the buckle 7.

[0047] In one embodiment, the hook structure is formed by extending the end of the support bar 6 along the gap between adjacent heat dissipation fins and bending it in a direction perpendicular to the heat dissipation fins. The structure is simple and adaptable to various complex transportation situations. Even if the product is inverted during transportation, the support bar 6 will always remain in the gap between the heat dissipation fins and will not come out. The bent part is limited and installed at the buckle 7, and its lateral movement is restricted by the stop part to ensure its support strength for the double tower structure.

[0048] In one embodiment, the support bar 6 is integrally formed from metal wire, which is lightweight, simple in structure, and can provide support for the dual heat dissipation fin assembly through its own elastic deformation. Optionally, the metal wire is made of copper wire or iron wire.

[0049] In one embodiment, the enhanced stability dual-tower heatsink further includes: a fan unit, the fan unit and the heatsink fin assembly being spaced apart in the airflow direction, including at least a first fan unit 9 disposed in the gap 3, and a connecting portion 61 of the support bar 6 extending along the airflow direction and penetrating the fan frame of the first fan unit 9. Optionally, the connecting portion 61 of the support bar 6 extends to the fan frame, the fan frame having a through hole with a rubber shock-absorbing ring embedded in the through hole, the connecting portion 61 penetrating the through hole and having an interference fit with the fan frame; optionally, the diameter of the through hole in the fan frame is larger than that of the support bar 6, and the support bar 6 penetrates the fan frame without contact. In other embodiments, the connecting portion of the support bar 6 extends along the airflow direction and is disposed on the outside of the first fan unit 9, which can also provide support force, constraining the first fan unit 9 in a preset position and preventing it from dislodging. (Added according to drawings)

[0050] In one embodiment, the heat pipe assembly 4 extends and is fixed at both ends to the interior of the first heat dissipation fin assembly 1 and the second heat dissipation fin assembly 2, respectively. The heat dissipation base 5 is disposed in the middle of the heat pipe assembly 4. The heat pipe assembly 4 is fixedly connected to the heat dissipation base 5. The heat from the heat source is conducted to the heat pipe through the heat dissipation base 5 and transferred to the external environment through the first heat dissipation fin assembly 1 and the second heat dissipation fin assembly 2.

[0051] In one embodiment, the enhanced stability dual-tower heat sink further includes a fixing bracket 10, with both ends of the fixing bracket 10 fixedly connected to the bottom of the two heat dissipation fin assemblies and the middle of the fixing bracket 10 fixedly connected to the heat dissipation base 5. Specifically, both ends of the fixing bracket 10 are fixed to the heat dissipation fin assemblies or their bases by self-tapping screws, and the middle is connected to the heat dissipation base 5 by a lock nut.

[0052] In one embodiment, the fixing bracket 10 is an inverted U-shaped bracket integrally stamped, and the fixing bracket 10 has mounting through holes 101 at both ends and the middle for fasteners to pass through. The fixing bracket 10 further enhances the overall bending strength and structural rigidity of the radiator, while its simple structure facilitates quick installation.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea and method of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
