Description

Technical field:

[0001] The utility model relates to the technical field of radiators, in particular to a radiator fan assembly. Background technology:

[0002] As the performance of electronic devices continues to improve, the power consumption and heat generation of their internal hardware are also increasing. This is especially true in areas such as computers, servers, smartphones, automotive electronics, and industrial equipment. Electronic components generate significant amounts of heat during operation. If this heat cannot be dissipated promptly and effectively, it can lead to decreased device performance, hardware damage, and even safety hazards. Therefore, heat dissipation has become a critical step in ensuring the stable operation of electronic devices, and the main function of a radiator fan is to accelerate heat dissipation through forced convection. Typically, a radiator fan is used in conjunction with a metal heat sink. The heat sink absorbs heat from the heat source, while the fan generates airflow through rotation, helping to remove the accumulated heat and discharge it outside the device.

[0003] The efficiency of a cooling fan depends on factors such as its rotational speed, size, blade design, and air flow rate. An efficient cooling fan can achieve rapid heat transfer while reducing noise through a large air flow rate and a fine blade design. For example: The utility model patent with the Chinese patent authorization announcement number CN202391779U discloses a quickly detachable fan structure. In the solution disclosed in the patent, a fan bracket 1, a fan frame 2 connected to the fan bracket 1, a radiator 3 is installed on the other side of the fan bracket 1, and a plurality of snap flanges 202 are provided at intervals on the outer circumference of the fan frame 2, and a snap seat 101 that matches the snap flange 202 is provided at the corresponding position of the fan bracket 1. As disclosed in the patent, most cooling fans currently on the market are supported by a structure similar to the fan frame 2, and the presence of the support plate in the fan frame 2 will affect the flow of air. Therefore, optimizing the support structure can improve the cooling efficiency of the cooling fan.

[0004] In view of this, the inventors propose the following technical solutions. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a radiator fan assembly.

[0007] Furthermore, in the above technical solution, the air guide slots are conical, and two are provided on each of the first support arm, the second support arm and the third support arm.

[0008] Furthermore, in the above technical solution, the first support arm, the second support arm and the third support arm are each provided with a first mounting hole for mounting a fan assembly, and the center of the middle table is provided with a hollow hole.

[0009] Furthermore, in the above technical solution, a wire trough positioning arm extending outward as a cantilever for positioning the wire harness is further provided on the middle table, and a wire trough buckle corresponding to the wire trough positioning arm and used to fix the wire harness is provided on the side wall of the cavity.

[0010] Furthermore, in the above technical solution, the end of the wire trough positioning arm is provided with a side opening groove for allowing the wire harness to pass through, and the bottom of the wire trough positioning arm is provided with a guide groove for guiding the wire harness, and a column hole located beside the guide groove.

[0011] Furthermore, in the above technical solution, the bracket is provided with two cavities for installing the fan group, and the supporting structures in the two cavities are symmetrically distributed, and the wire groove buckles on the outer walls of the two cavities are located in the middle of one side of the bracket, and the side of the bracket is provided with multiple wire harness buckles located in the middle and used to clamp the wire harness.

[0012] Furthermore, in the above technical solution, one side of the first support arm, the second support arm, and the third support arm is provided with an R chamfer, and the R chamfer tends to be toward the air inlet end of the support structure.

[0013] Furthermore, in the above technical solution, a heat dissipation body is also installed at the bottom of the bracket, which includes a first fin group, a second fin group, a third fin group, a heat pipe passing through the first fin group, the second fin group and the third fin group, and a first connecting piece and a second connecting piece of the heat pipe connecting the first fin group, the second fin group and the third fin group in series, wherein the fan group and the heat dissipation body are respectively located on both sides of the supporting structure.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the present invention, by providing a plurality of air guide slots on the support structure, more air can be blown into the heat dissipation body by using the air guide slots, thereby taking away more heat from the radiator body. Secondly, by setting the air guide slots to be conical, and taking advantage of the different sizes of the two sides of the cone, a pressure difference can be generated after the wind passes through the air guide slots, which not only changes the flow rate and improves the heat dissipation efficiency, but also forms a temperature difference on both sides of the support structure as the pressure changes, further improving the heat dissipation. In addition, by providing R chamfers on the windward surfaces of the first support arm, the second support arm, and the third support arm, wind resistance can be reduced and heat dissipation efficiency can be improved.

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] See Figures 1 to 4 The figure shows a radiator fan assembly, comprising a bracket 1 and at least one fan group 2 mounted on the bracket 1. The bracket 1 is provided with at least one cavity 3 for accommodating the fan group 2, and the cavity 3 is provided with a support structure 4 for mounting and fixing the fan group 2. The support structure 4 includes a middle table 41 and at least three first support arms 42, a second support arm 43, and a third support arm 44 extending in all directions from the middle table 41. Each of the first support arm 42, the second support arm 43, and the third support arm 44 is provided with at least one air guide slot 45. By providing multiple air guide slots 45 on the support structure 4, more air can be blown into the heat sink 5 using the air guide slots 45, thereby removing more heat from the heat sink 5.

[0021] The air guide slots 45 are tapered, with two each provided on the first support arm 42, the second support arm 43, and the third support arm 44. By configuring the air guide slots 45 in a tapered shape and utilizing the different sizes on either side of the tapered shape, a pressure difference is generated after the air passes through the air guide slots 45. This not only changes the flow rate and improves heat dissipation efficiency, but also creates a temperature difference on both sides of the support structure 4 as the pressure changes, further enhancing heat dissipation.

[0022] The first support arm 42 , the second support arm 43 and the third support arm 44 are each provided with a first mounting hole 46 for mounting the fan assembly 2 , and a hollow hole is provided at the center of the middle table 41 .

[0023] The middle table 41 is also provided with a wire trough positioning arm 47 that extends outward and is used to position the wiring harness. A wire trough buckle 31 is provided on the side wall of the cavity 3, corresponding to the wire trough positioning arm 47 and used to secure the wiring harness. The end of the wire trough positioning arm 47 is provided with a side opening slot 471 for the wiring harness to pass through. The bottom of the wire trough positioning arm 47 is provided with a guide slot 472 for guiding the wiring harness, and a column hole 473 located next to the guide slot 472. By providing an outward-extending wire trough positioning arm 47 on the middle table 41, the wire trough positioning arm 47 is used to position the wires connected to the fan assembly 2, ensuring that the wires do not shake when the fan assembly 2 is operating. This not only reduces noise generation, but also does not affect the normal operation of the fan assembly 2 and does not create resistance to the heat dissipation air.

[0024] The bracket 1 is provided with two cavities 3 for installing the fan group 2, and the support structures 4 in the two cavities 3 are symmetrically distributed, and the wire groove buckles 31 on the outer walls of the two cavities 3 are located in the middle of one side of the bracket 1, and the side of the bracket 1 is provided with multiple wire harness buckles 11 located in the middle and used to clamp the wire harness.

[0025] An R chamfer 48 is provided on one side of the first support arm 42, the second support arm 43, and the third support arm 44, and the R chamfer 48 is inclined toward the windward end of the support structure 4. By providing the R chamfer 48 on the windward surface of the first support arm 42, the second support arm 43, and the third support arm 44, wind resistance is reduced and heat dissipation efficiency is improved.

[0026] A heat dissipation body 5 is also installed at the bottom of the bracket 1, and the heat dissipation body 5 includes a first fin group 51, a second fin group 52, a third fin group 43, a heat pipe 54 passing through the first fin group 51, the second fin group 52 and the third fin group 43, and a first connecting piece 55 and a second connecting piece 56 that are connected in series with the first fin group 51, the second fin group 52 and the third fin group 53, wherein the fan group 2 and the heat dissipation body 5 are respectively located on both sides of the support structure 4.

[0027] In summary, in the present invention, by providing air guide slots 45 on the support structure 4 of the bracket 1, when the fan assembly 2 is operating, the generated airflow can pass through the air guide slots 45, reducing the support structure 4's obstruction to the heat dissipation air. Furthermore, the air guide slots 45 are configured in a conical shape, so that when the air passes through, a pressure difference is generated due to the change in cross-section. This not only increases the air flow rate, but also the pressure difference can produce a temperature difference effect, further improving the heat dissipation effect. To further reduce the resistance to air passing through the support structure 4, R-chamfers 48 are provided on one side of the first support arm 42, the second support arm 43, and the third support arm 44. This inclined chamfer structure allows the heat dissipation air to quickly pass through the support structure 4, further reducing the support structure 4's impact on the heat dissipation air and improving the heat dissipation efficiency.

[0028] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
