Description

Technical Field

[0001] The utility model relates to a heat dissipation device, in particular to a coordinated and stable heat dissipation fan. Background Art

[0002] For high-power electronic components (such as CPUs) within a computer chassis, cooling fans are typically installed on these components to dissipate heat. Existing cooling fans typically consist of a fan body, heat sinks, and clips. The fan body and heat sinks are mounted using clips. During installation, one end of the clip is attached to the heat sink, and the other end is attached to the fan body. This requires additional molding of the clips on the heat sink, increasing the difficulty of heat sink processing and causing problems for manufacturers. Utility Model Content

The fan body comprises a shell body, the upper end face and the bottom face of the shell body are respectively provided with two concave functional grooves. A guide groove is provided on the groove wall of the functional groove on the side of the heat sink group. The guide groove comprises a lead-in section near the notch position of the functional groove and a lead-in section near the inside of the functional groove. The straight section of the position is provided with a horizontally inwardly extending card hole on the inner wall of the straight section of the shell body, and the fixing strip includes a main section, two connecting sections vertically connected to the two ends of the main section, and two card sections respectively connected vertically to the two connecting sections.

[0023] See also Figures 1 to 4 The present invention provides a stable cooling fan for dissipating heat from high-power electronic components within a computer chassis. The stable cooling fan comprises a base 10, a copper tube 20 mounted on the base 10, a heat sink 30 mounted on the copper tube 20, a fan body 40 disposed on the front and rear sides of the heat sink 30, and four fixing bars 50 for securing the fan body 40. During installation, the bottom of the base 10 fits against the high-power electronic components, and the base 10 is secured to the computer chassis via fixings.

[0024] The base 10 is made of an aluminum alloy with excellent thermal conductivity. The bottom of the base 10 is provided with several horizontally extending retaining grooves 11 with downward-facing notches. Multiple copper tubes 20 are arranged in a U-shape with a flat bottom. They are mounted in the retaining grooves 11 of the base 10, with the bottom of the copper tubes 20 flush with the bottom of the base 10. When the base 10 is installed in the chassis, the base 10 compresses the copper tubes 20.

[0025] The heat sink assembly 30 includes a plurality of heat sink bodies 31 arranged in a vertically arranged sequence, and two connecting fins 32 disposed on either side of the heat sink bodies 31. The heat sink bodies 31 are evenly spaced apart and secured to the connecting fins 32 by welding or other means, thereby forming a single integral connection between the heat sink bodies 31 and the connecting fins 32. Each heat sink body 31 is provided with a plurality of groups of through-holes 311, with different groups of through-holes 311 arranged in a forward-backward direction. Each group of through-holes 311 comprises two through-holes 311. Each group of through-holes 311 is mounted in conjunction with a copper tube 20. The U-shaped copper tube 20 passes through two through-holes 311 in the same group. The upper end of the copper tube 20 extends from the topmost heat sink body 31. The topmost and bottommost heat sink bodies 31 are welded and secured to the copper tube 20, with the inner walls of the through-holes 311 tightly fitting the outer walls of the copper tube 20.

[0026] The fan body 40 includes a shell body 41, a driving motor (not shown) installed on the shell body 41, and fan blades 42 connected to the driving motor. The shell body 41 is roughly square in shape, and two concave functional grooves 411 are respectively provided on the upper end surface and the bottom surface of the shell body 41. A guide groove 412 is provided on the groove wall of the functional groove 411 on the side of the heat sink group 30. The guide groove 412 includes an inlet section 413 near the notch position of the functional groove 411 and a straight section 414 near the internal position of the functional groove 411. The inner wall of the inlet section 413 is inclined to form an inclined guide surface. The shell body 41 is provided with a horizontally inward extending card hole 415 on the inner wall of the straight section 414.

[0027] The fixing bar 50 is arranged in a strip shape as a whole. The material of the fixing bar 50 is metal that can undergo a certain deformation. The fixing bar 50 includes a main section 51, two connecting sections 52 vertically connected to the two ends of the main section 51, and two locking sections 53 vertically connected to the two connecting sections 52 respectively. The two locking sections 53 are arranged between the two connecting sections 52, and the extension direction of the locking section 53 is parallel to the extension direction of the main section 51.

[0028] During assembly, the two fan bodies 40 are positioned front and rear on either side of the heat sink assembly 30, facing each other. The two locking sections 53 of the fixing bar 50 extend into the guide slots 412 of the two fan bodies 40 and slide over the inclined guide surfaces. The inclined guide surfaces squeeze the connecting section 52 and the locking section 53 of the fixing bar 50, causing the connecting section 52 of the fixing bar 50 to elastically deform outward. As the locking section 53 moves inward toward the guide slots 412, it snaps into the locking hole 415, and the main section 51 of the fixing bar 50 abuts against the topmost or bottommost heat sink body 31. Multiple fixing bars 50 are assembled with the two fan bodies 40, thereby securing the fan bodies 40 from both top and bottom. The two fixing bars 50 on the top and the main sections 51 of the two fixing bars 50 on the bottom are locked between the U-shaped copper tubes 20, which limit the fixing bars 50.

[0029] The beneficial effect of the present invention in conjunction with a stable cooling fan is that: by providing a guide groove 412 and a clamping hole 415 on the two fan bodies 40, the fixing strip 50 includes a main body section 51, two connecting sections 52 vertically connected to the two ends of the main body section 51, and two clamping sections 53 respectively vertically connected to the two connecting sections 52. During assembly, the clamping sections 53 slide through the guide groove 412 and are clamped into the clamping holes 415. The plurality of fixing strips 50 are installed in conjunction with the two fan bodies 40, thereby fixing the fan bodies 40 from the upper and lower sides. The present invention does not require additional buckles on the heat sink group 30, effectively reducing the processing difficulty of the heat sink group 30. In addition, the overall structure is stable, flexible, and highly practical.
