Description

Technical Field

[0001] The utility model relates to the technical field of radiator structures, in particular to a heat dissipation fan connector wire fixing structure. Background Art

[0002] The radiator fan is used to dissipate heat accumulated inside the radiator. A motor drives the fan blades, generating airflow to remove the heat. The motor's power supply is connected to the motherboard via a connector. The length and position of the connector cable determine the radiator's installation location and usage.

[0003] CN200620157175.4 discloses a power connector for a cooling fan, which is mounted on a cooling fan housing. A mounting portion is formed on one end of the housing, with mounting walls on either side of the mounting portion. Each mounting wall is provided with a protrusion, and the two protrusions extend into the mounting portion. The power connector comprises an insulating housing, a plurality of power boards, and at least one grounding plate. The insulating housing has a recess in which the power boards and grounding plate are housed. The insulating housing has a slot on either side. The two protrusions are housed in the slots on either side of the insulating housing. The slots are longer in their longitudinal direction than the protrusions, and the width between the two sides of the insulating housing is less than the width between the inner surfaces of the two mounting walls. This structure allows the power connector to be placed in a floating position, preventing positional deviation during insertion and requiring repeated insertion.

[0004] The thickness of a radiator is composed of the heat sink and the cooling fan, with the fan connector extending from one side. To reduce overall thickness and achieve miniaturization, existing radiators have slots cut into the fins to allow the fan to fit inside. However, this prevents the connecting wires from being properly secured, creating a risk of loosening during use and potentially damaging the radiator. Utility Model Content

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference below Figures 1-4 The heat dissipation fan connector wire fixing structure according to an embodiment of the present utility model is described.

[0032] like Figures 1-4 As shown, it includes a heat sink 100 and a heat dissipation fan 210. The heat sink 100 includes a contact portion 110 and heat-conducting fins 120. The contact portion 110 and the heat-conducting fins 120 are integrally formed. The heat-conducting fins 120 are hollowed out in the middle area corresponding to the contact portion 110. The heat-conducting fins 120 adopt a strip grid structure. The bottom of the contact portion 110 is in contact with the heat source, and the heat of the heat source is accumulated in the heat-conducting fins 120 through the contact portion 110.

[0033] The diameter of the hollowed-out area in the center of the thermal fins 120 is larger than that of the cooling fan 210. The cooling fan 210 is mounted in this hollowed-out area of ​​the contact portion 110. The cooling fan 210 generates airflow, promoting the dissipation of heat from the thermal fins 120 into the air. The cooling fan 210 is equipped with a connector cable 220. One end of the connector cable 220 is connected to the cooling fan 210, and the other end extends through the thermal fins 120 to the outside world. When plugged into the power supply motherboard, the connector cable 220 provides power to the cooling fan 210.

[0034] The connector cable 220 is laid in the same direction as the thermal fins 120. The connector cable 220 is inserted into the mounting groove 130 formed by the two thermal fins 120. A removable silicone pad 140 is positioned above the mounting groove 130 to compress the connector cable 220 within the mounting groove 130.

[0035] Specifically, the location of the mounting slot 130 is determined by the position where the connector cable 220 extends from the cooling fan 210. The connector cable 220 and the mounting slot 130 are laid in a straight line, reducing bending of the connector cable 220. After the connector cable 220 is laid in the mounting slot 130, the silicone pad 140 blocks the top of the mounting slot 130, pressing down on the connector cable 220 to prevent the connector cable 220 from loosening. The cooperation between the mounting slot 130 and the silicone pad 140 reduces the vibration of the connector cable 220, effectively preventing the safety hazards caused by the connector cable 220 becoming loose.

[0036] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the width of the mounting slot 130 is equal to that of the connector cable 220. Specifically, the cooling fan 210 typically utilizes a 4-pin structure, and the spacing between the three thermal fins 120 matches the width of the 4-pin connector cable 220. Based on the extension position of the connector cable 220, the center heat dissipation fins of the three thermal fins 120 are cut away to form the mounting slot 130 at the corresponding position. Using this arrangement density of thermal fins 120 can reduce the manufacturing cost of heat sinks of different specifications and improve production efficiency.

[0037] In some embodiments of the present invention, Figure 1 As shown, the thermal fins 120 are provided with through mounting holes 121, and the two sides of the silicone pad 140 are fixed in the mounting holes 121 on both sides of the mounting groove 130. Specifically, in order to fix the silicone pad 140 in the mounting groove 130, through mounting holes 121 are provided on the thermal fins 120 at the corresponding positions of the silicone pad 140 to facilitate the installation of the silicone pad 140. In this embodiment, all thermal fins 120 are provided with mounting holes 121, which is convenient for subsequent adjustment of the position of the mounting groove 130 without the need to drill new holes, thereby improving processing efficiency. In addition, the processing difficulty of drilling holes in one of the thermal fins 120 is higher than the processing difficulty of drilling holes in all the thermal fins 120, which is not conducive to improving production efficiency and yield rate.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the two side walls of the silicone pad 140 are provided with protrusions 141, which cooperate with the mounting holes 121. Specifically, the silicone pad 140 and the protrusions 141 are integrally formed and have elasticity. When the silicone pad 140 is in the mounting groove 130, the two protrusions 141 are in a compressed state. When the silicone pad 140 is aligned with the mounting hole 121, the two compressed and deformed protrusions 141 return to their original shape and fit into the mounting hole 121, thereby fixing the silicone pad 140 in the mounting groove 130.

[0039] Furthermore, the main body of the silicone pad 140 can be cylindrical, prismatic, or spherical. In this embodiment, the silicone pad 140 is prismatic. The bottom of the silicone pad 140 abuts the connector cable 220 in the mounting groove 130 to prevent the connector cable 220 from loosening. The silicone pad 140 primarily compresses the connector cable 220 through its end surface adjacent to the mounting groove 130. The main body of the silicone pad 140 can be of any shape.

[0040] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, one side of the silicone pad 140 is flush with the edge of the thermal fin 120 and the contact portion 110. Specifically, to prevent the connector cable 220 from warping near the edge of the contact portion 110, the silicone pad 140 is installed near the edge of the contact portion 110 to press the edge of the connector cable 220.

[0041] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the side of the contact portion 110 close to the heat conducting fins 120 is in an arc-shaped convex shape. Specifically, the arched middle portion of the contact portion 110 can absorb more heat and improve the heat transfer efficiency.

[0042] Furthermore, if Figure 1 As shown, the top end surface of the heat dissipation fan 210 is lower than the top end surface of the heat conducting fin 120. This enables the heat dissipation fan 210 to better promote the air flow in the hollowed-out portion of the heat conducting fin 120.

[0043] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the illustrative use of the above terms does not necessarily refer to the same embodiment or example.
