Detailed Implementation

[0025] 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.

[0026] A low-noise, high-airflow disc fan for use in a laptop cooling bracket includes a fan frame 1, a mounting component, a cleaning component, and a cooling component. The mounting component includes extension blocks 2, with two extension blocks 2 fixed to the lower end of the fan frame 1.

[0027] A base 3 is provided below the fan frame 1. Three positioning bolts 4 are threaded inside the two extension blocks 2. The lower end of the positioning bolts 4 is threaded inside the extension block 2. Two pairs of sliding grooves 5 are opened on the inner side of the fan frame 1. Two pairs of sliding blocks 6 are fixedly provided on the top of the base 3. The two pairs of sliding blocks 6 slide inside the two pairs of sliding grooves 5 respectively.

[0028] like Figure 1 , Figure 2 and Figure 4 Slide the fan frame 1 onto the upper surface of the base 3, so that the sliding block 6 slides inside the sliding groove 5. Insert the positioning bolt 4 into the extension block 2 and the base 3 to fix the fan frame 1 to the upper surface of the base 3.

[0029] The cleaning assembly includes a top cover 7, which is slidably disposed above the fan frame 1. A protrusion 8 is fixedly disposed on the inner side of the top cover 7. A groove 9 is provided on the upper surface of the fan frame 1, and the lower end of the protrusion 8 is slidably disposed inside the groove 9.

[0030] like Figure 1 , Figure 2 and Figure 3 The top cover 7 is slidably placed above the fan frame 1, so that the lower end of the protrusion 8 slides inside the groove 9, thereby controlling the position between the top cover 7 and the fan frame 1.

[0031] A cleaning brush 10 is fixedly installed on the inner side of the top cover 7, a handle 11 is fixedly installed on the upper surface of the top cover 7, two pairs of placement slots 12 are opened on the lower surface of the fan frame 1, a filter plate 13 is slidably installed inside the two pairs of placement slots 12, and several round holes 14 are opened on the outer surface of the two pairs of filter plates 13.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 By rotating the top cover 7 with the handle 11, the cleaning brush 10 slides inside the fan frame 1. Since the lower surface of the fan frame 1 has two pairs of placement slots 12, the two pairs of filter plates 13 are slidably inserted into the two pairs of placement slots 12.

[0033] Positive magnetic blocks 15 are fixedly installed on the inner side of each pair of filter plates 13, and negative magnetic blocks 16 are fixedly installed inside each pair of placement slots 12. The two pairs of positive magnetic blocks 15 are adsorbed and installed on one side of the two pairs of negative magnetic blocks 16.

[0034] like Figure 4 and Figure 5 The filter plate 13 is slidably inserted into the placement groove 12, so that the positive magnetic block 15 is attracted to one side of the negative magnetic block 16, thus fixing the filter plate 13 inside the placement groove 12.

[0035] The heat dissipation component includes rectangular holes 17, and several rectangular holes 17 are evenly opened on the outer surface of the fan frame 1. A circular hidden groove 18 is opened on the lower surface of the base 3.

[0036] like Figure 4 and Figure 6 Since the outer surface of the fan frame 1 has several rectangular holes 17, the filter plate 13 is placed inside the rectangular holes 17 to cover the inside of the fan frame 1. A circular hidden groove 18 is opened on the lower surface of the base 3.

[0037] The hidden slot 18 has two pairs of heat dissipation holes 19 inside, and a rectangular block heat dissipation block 20 is fixedly installed inside the hidden slot 18.

[0038] like Figure 6 Two pairs of heat dissipation holes 19 are opened inside the hidden slot 18, and a heat sink 20 is fixed inside the hidden slot 18. The heat dissipation holes 19 and the heat sink 20 work together to dissipate heat from the fan frame 1.

[0039] The working principle of the low-noise, high-airflow disc fan for laptop cooling brackets provided by this utility model is as follows:

[0040] When using a laptop, a cooling bracket is needed to dissipate heat. The filter plate 13 is slid into the placement slot 12, so that the positive magnet 15 is attracted to one side of the negative magnet 16. The filter plate 13 is placed inside the rectangular hole 17. The fan bracket 1 is slidably placed on the upper surface of the base 3. The positioning bolt 4 is threaded into the extension block 2 and the base 3. The top cover 7 is placed on the upper surface of the fan bracket 1 using the handle 11. The fan bracket 1 is cleaned using the cleaning brush 10. The rectangular hole 17, the heat dissipation hole 19 and the heat dissipation block 20 work together to dissipate heat from the fan bracket 1.

[0041] Compared with related technologies, the low-noise, high-airflow disc fan for laptop cooling stands provided by this utility model has the following advantages:

[0042] This utility model includes an installation component such as an extension block 2 and a base 3, a cleaning component such as a top cover 7 and a protrusion 8, and a filter plate 13 placed inside a placement slot 12. By rotating the top cover 7, the cleaning brush 10 cleans the fan frame 1, removes dust from inside the fan frame 1, and prevents it from affecting the operation of the electronic components inside the fan.

[0043] Since the heat dissipation assembly includes rectangular holes 17 and hidden slots 18, the rectangular holes 17, heat dissipation holes 19 and heat sinks 20 work together to dissipate heat from the inside of the fan frame 1, preventing the electronic components inside the fan from burning out.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
