Description

Technical Field

[0001] The utility model relates to a heat dissipation device, in particular to a tightly fastened heat dissipation fan. Background Art

[0002] A cooling fan is a device used to dissipate heat, commonly found in computers and other electronic devices. It primarily transfers heat from a heat source (such as a computer motherboard) to the surrounding air, thereby cooling the device. This cooling function helps maintain a stable operating temperature and prevents performance degradation or damage due to overheating. The technology and performance of cooling fans have reached a mature stage, with new technologies constantly emerging.

[0003] The cooling fan includes a cooling fan body, a heat sink group, and fasteners for fixing the fan body to the heat sink group. Since the heat sink group is made of metal sheets with poor elastic deformation ability, when the fasteners are fastened to the heat sink, a gap is likely to appear between the cooling fan body and the heat sink group, resulting in a loose fit between the cooling fan body and the heat sink group and loud noise.

[0025] See also Figures 1 to 5 The utility model provides a tightly fitting cooling fan, comprising a copper tube 10, a heat sink group 20 mounted on the copper tube 10, a base 30 mounted on the heat sink group 20, support legs 40 mounted on the base, a cooling fan body 50 mounted on the heat sink group 20, and a plurality of buffer members 60 clamped between the cooling fan body 50 and the heat sink group 20, wherein the material of the buffer members 60 is silicone.

[0026] The heat sink assembly 20 is composed of a plurality of heat sinks 21, which are spaced horizontally apart. A set of through-holes 212 are provided on each side of the heat sink assembly 20. The copper tubes 10 are provided in two groups for the tight-fitting cooling fan, each of which is mounted on the through-holes 212 on either side of the heat sink assembly 20. Snap-on notches 211 are provided on each side of the heat sink 21. The snap-on notches 211 on the same side of the heat sink 21 align with each other and form a slot 22. Furthermore, the edges of the heat sink 21 are inclined, forming an inclined guide surface 23 on the same side of the heat sink 21.

[0027] The cooling fan body 50 includes a housing body 51, a driving motor mounted on the housing body 51, fan blades 52 mounted on the motor, a plurality of positioning seats 53 connected to the housing body 51, two limiting plates 54 connecting two adjacent positioning seats 53 and arranged oppositely, and two retaining plates 55 connecting two adjacent connecting seats and arranged oppositely. In this embodiment, the housing body 51 is generally annular in shape, the limiting plates 54 are connected to the outer circumferential surfaces of the positioning seats 53, and the retaining plates 55 are connected to the outer circumferential surfaces of the positioning seats 53. The limiting plates 54 and retaining plates 55 are evenly spaced in the circumferential direction. The retaining plates 55 are inclined downward and outward, and a retaining strip 551 is provided on the inner side of the retaining plates 55. In this embodiment, the shell body 51 is made of plastic and has certain elastic deformation characteristics. When the limit plate 54 and the locking plate 55 of the shell body 51 are pressed outward, the limit plate 54 and the locking plate 55 can bend outward. After the limit plate 54 and the locking plate 55 are released, the limit plate 54 and the locking plate 55 return to their original position elastically.

[0028] The positioning seat 53 is provided with a recess 531 between the adjacent limiting plate 54 and the locking plate 55, and the positioning seat 53 is also provided with a stop portion 532 extending into the recess 531 in the vertical direction. The bottom surface of the locking portion is flat, and the bottom of the stop portion 532 is provided with a plurality of upwardly extending fixing grooves 5321.

[0029] The buffer members 60 correspond one-to-one to the positioning seats 53. Each buffer member 60 includes a main body 61 and a plurality of protrusions 62 protruding from the upper end surface connected to the main body 61. The bottom of the main body 61 is flat. The buffer member 60 made of silicone material has elastic deformation characteristics.

[0030] During assembly, the buffer member 60 is installed on the stop portion 532 of the positioning seat 53, and the protrusion 62 of the buffer member 60 is inserted into the fixing groove 5321 of the stop portion 532. In addition, the outer diameter of the protrusion 62 is slightly larger than the groove width of the fixing groove 5321, so that the buffer member 60 installed on the positioning seat 53 is not easy to fall off, and the bottom of the main body 61 of the buffer member 60 extends out from the recess 531. Then install the shell body 51 of the cooling fan body 50 on the heat sink group 20, and the two limit plates 54 on the shell body 51 are clamped on the heat sink group 20 from the front and rear sides. The two clamping plates 55 of the shell body 51 slide over the inclined guide surface 23 of the heat sink group 20. When the clamping plate 55 slides over the inclined guide surface 23, the inclined guide surface 23 squeezes the clamping strip 551 of the clamping plate 55 outward until the clamping strip 551 slides to a position close to the clamping slot 22 on the heat sink group 20, further pressing the cooling fan body 50, and the stop portion 532 presses the buffer 60. The buffer 60 elastically deforms and the clamping strip 551 is clamped into the clamping slot 22.

[0031] The beneficial effect of the tightly fitting cooling fan of the present invention is that: by arranging a locking plate 55 and a limiting plate 54 on the shell body 51 of the cooling fan body 50, and a clamping strip 551 on the locking plate 55, during assembly, the two limiting plates 54 on the shell body 51 are clamped on the heat sink group 20 from the front and back sides, and the two locking plates 55 on the shell body 51 are clamped on the heat sink group 20 from the left and right sides, and the clamping strip 551 is clamped into the clamping slot 22, thereby realizing rapid installation of the cooling fan body 50 and the heat sink group 20. After installation, the buffer component 60 is clamped between the cooling fan body 50 and the heat sink group 20, so that the cooling fan body 50 and the heat sink group 20 are tightly matched, effectively reducing noise.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
