Description

Technical Field

[0001] The utility model relates to the technical field of fan accessories, and in particular to a fan frame of a heat dissipation fan which can be used in new energy industries, servers, energy storage, industrial equipment, automobiles, cabinets and other products. Background Art

[0002] In products such as energy storage equipment, industrial equipment or computer cases, since various hardware such as power supplies generate a lot of heat, special fans are generally required for heat dissipation. The fan generally installs the motor on the motor mounting base in the middle of the fan frame. The outer frame outside the fan frame and the middle base are generally connected as an integrated structure through several connecting ribs. At the same time, some will set up independent wire troughs between the outer frame and the base to route the power wires, such as the improved fan with a wire cover disclosed in patent CN219932478U. Others do not set up independent wire troughs, and directly allow the wires to pass through the space between the base and the outer frame for routing, such as the cooling fan outlet structure disclosed in patent CN220706049U.

[0003] Both of the above methods have their own shortcomings. If an independent wire trough is not set, the wires are directly exposed in the air outlet channel. Sometimes the fan may inhale some sand, gravel, metal debris, etc., which may hit the wires during high-speed flight, causing the protective layer of the wires to be damaged or even broken. If an independent wire trough is set, the independent wire trough is generally large in size and cannot be arranged alone between two adjacent connecting ribs that are normally set. Therefore, it is necessary to change the original setting structure of the connecting ribs and replace the two connecting ribs with wire troughs. In this way, firstly, the air outlet channel will be obviously occupied due to the large width of the wire trough, affecting the air intake; secondly, because the wire trough replaces the two connecting ribs, the spacing between the connecting ribs will change from normal to wider, which will affect the overall structural strength of the fan frame. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fan frame with a more reasonable structural design, which can prevent the wires from being hit by foreign objects, will not affect the air intake, can improve the structural strength and can protect the wires in view of the shortcomings of the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a fan frame capable of protecting wires, comprising an outer frame and a base, the base being located in the middle of the outer frame, the outer frame and the base being connected into an integral structure by a plurality of evenly arranged connecting ribs, the space between the connecting ribs forming an air outlet channel, characterized in that: a wire protection groove is arranged between two adjacent connecting ribs, the width of the wire protection groove is substantially equivalent to the width space occupied by the connecting ribs, and the space between the two adjacent connecting ribs is divided into left and right parts by the wire protection groove; one end of the wire protection groove is connected to the base to form a wire inlet, and the other end is connected to the outer frame to form a wire outlet; the windward surface of the wire protection groove is a convex arc surface structure, and the leeward surface of the wire protection groove is a concave groove structure, the wire enters the groove structure of the wire protection groove through the wire inlet and extends out of the fan frame from the wire outlet.

[0006] Furthermore, wire clamping openings are respectively provided on the base on both sides of the wire inlet, and wire clamping openings are also respectively provided on the outer frame on both sides of the wire outlet. Wire clamps are provided in the wire clamping openings to respectively clamp the wires at the wire inlet and the wire outlet, so that the wires are embedded in the groove structure of the wire strip.

[0007] Furthermore, the wire protection groove has an arc-shaped structure from the inside to the outside, and the wire protection groove is connected with the outer frame and the base as an integrated structure.

[0008] Furthermore, screw columns are respectively arranged at the four corners of the outer frame, and hollow grooves are provided on the left and right sides of the screw columns, which is beneficial to reducing material usage and reducing costs; the inner side of the screw column is connected to the outer frame through a connecting part to form an integrated structure, thereby improving the structural strength of the screw installation part, so as to avoid the situation where the traditional fan frame only extends out of the upper and lower parts of the fixed part, resulting in low structural strength.

[0009] Furthermore, a hollow portion is provided between the upper and lower surfaces of the outer frame and the screw column, which can reduce the amount of material used without significantly reducing the structural strength, thereby further reducing costs.

[0010] Furthermore, the inner wall surface of the air outlet side of the outer frame is arranged as a section of guiding inclined surface, and the guiding inclined surface is inclined outward from front to back to form a wider air guiding surface.

[0011] Furthermore, a reinforcement portion is provided between the outer end of the connecting rib and the guiding inclined surface, the end of the reinforcement portion is a gradually pointed structure, and a guiding groove which gradually widens from front to back is formed between the reinforcement portion and the guiding inclined surface.

[0012] The utility model sets an independent wire protection groove between the outer frame and the base. The wire protection groove is located between two adjacent connecting ribs arranged normally, and the width of the wire strip is substantially equivalent to the width space occupied by the connecting rib. In this way, the wire can be used for routing the wires without substantially affecting the air intake, and the wires are protected to prevent foreign objects from being sucked in and hitting the wires. At the same time, it can also play the effect of adding a connecting rib, thereby improving the overall structural strength of the fan frame. BRIEF DESCRIPTION OF THE DRAWINGS

The wire protection groove 4 divides the space between the two adjacent connecting ribs 3 into two parts, which can be used for air outlet respectively, so the impact on the air outlet area is much smaller than that of the traditional large-sized wire groove; one end of the wire protection groove 4 is connected to the base 2 to form an inlet 41, and the other end is connected to the outer frame 1 to form an outlet 42; the windward surface of the wire protection groove 4 is a convex arc surface structure, which can reduce the resistance to wind and reduce the impact on the air volume. The leeward surface of the wire protection groove 4 is a concave groove structure, and the wire enters the groove structure of the wire bar 4 through the inlet 41 and extends out of the fan frame from the outlet 42.
