Description

Technical Field

[0001] The present invention relates to a heat dissipation fan, in particular to a turbocharged fan. Background Art

[0002] The most common fan blade design is that the blade is fixed to the hub outside the motor housing through the root. Please refer to Figure 1 As shown in the figure, the air inlet blades of this fan are disturbed as the fan blades rotate, resulting in obvious interference between the air inlet and outlet, and low static pressure of the fan. When used in the system, under the action of impedance, the air outlet is insufficient and the heat dissipation performance is poor.

[0003] Currently, some fan blades are designed without roots. Although this structure does not cause turbulence, it also has poor performance due to the reduction in wind cutting area. Summary of the Invention

[0006] As a further improvement of the present invention, the fixing ring is a straight cylindrical structure matching the side wall of the motor housing.

[0007] As a further improvement of the present invention, the outer blades are arc-shaped structures extending in a straight line along the axial direction of the motor housing and in a curved line along the radial direction of the motor housing.

[0008] As a further improvement of the present invention, the turbocharger blade is a twisted arc sheet structure extending along the axial curve of the motor housing and spirally twisted along the radial direction of the motor housing, and the concave surface of the worm gear booster blade curve is in the same direction as the concave surface of the outer blade curve.

[0009] As a further improvement of the present invention, the number of the outer blades is greater than or equal to the number of the turbocharger blades, and the number of the outer blades is an integer multiple of the turbocharger blades.

[0010] As a further improvement of the present invention, the middle position of the end of the turbocharger blade is cross-connected with the middle position of the outer blade.

[0011] As a further improvement of the present invention, the guide web ring is located at one end of the motor housing opening, and the turbocharger blades and the outer blades are fixedly connected to the guide web ring on the side wall of the motor housing opening.

[0012] As a further improvement of the present invention, the outer blades and the turbocharger blades are evenly spaced and distributed along the circumference of the motor housing.

[0014] As a further improvement of the present invention, the turbocharger blades, the fixing ring, the outer blades and the guide web ring are an integrally formed structure.

[0015] The beneficial effects of the present invention are as follows: the fan blades of the present invention eliminate the connection between the blade root and the hub, and the outer blades are connected to the fixed ring on the outside of the motor housing through the guide web ring and the turbocharger blade, thereby achieving pressure and flow increase on the air inlet surface of the fan, increasing the air intake volume and air intake pressure of the fan, thereby improving the air outlet pressure and air outlet volume, and greatly improving the heat dissipation capacity of the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the structural principle of the prior art;

[0017] Figure 2 It is a schematic diagram of the structural principle of the present invention. DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0019] Example: Please refer to Figure 2 As shown, a turbocharged fan includes a motor housing 1, turbocharged blades 2, a fixed ring 3, outer blades 4, and a guide web ring 5. The fixed ring 3 is fixedly mounted on the outer circumference of the motor housing 1, and the guide web ring 5 is coaxially mounted on the outer circumference of the fixed ring 3. A plurality of outer blades 4 are fixedly mounted on the guide web ring 5 at radial intervals, and the ends of a plurality of worm gear booster blades are fixedly connected to the fixed ring 3 and the guide web ring 5 respectively. The turbocharged blades 2 are used to significantly increase the inlet and outlet air volume and pressure when the fan blades rotate. The guide web ring 5 fixes the outer blades 4 and the ends of the turbocharged blades 2, preventing disturbances during the fan blade rotation. At the same time, the guide web ring 5 also guides the airflow, allowing it to flow rapidly.

[0020] The fixing ring 3 is a straight cylindrical structure that matches the side wall of the motor housing 1. This structure is simple and avoids a step-type design.

[0021] The outer blades 4 are arc-shaped structures extending in a straight line along the axial direction of the motor housing 1 and in a curved line along the radial direction of the motor housing 1, which is conducive to guiding the wind direction.

[0022] The turbocharger blade 2 is a twisted arc sheet structure extending along the axial curve of the motor housing 1 and spirally twisted along the radial direction of the motor housing 1, and the concave surface of the worm gear booster blade curve is in the same direction as the concave surface of the outer blade 4 curve.

[0023] The number of outer blades 4 is greater than or equal to the number of turbocharger blades 2, and the number of outer blades 4 is an integer multiple of the number of turbocharger blades 2. Each turbocharger blade 2 forms a group with one or more outer blades 4. The turbocharger blades 2 are sparser than the outer blades 4, which is conducive to the inflow and outflow of large air volumes.

[0024] The middle position of the end of the turbocharger blade 2 is cross-connected with the middle position of the outer blade 4.

[0025] The guide web ring 5 is located at one end of the motor housing 1 in the direction of the opening, and the side wall of the turbocharger blade 2 and the outer blade 4 facing the opening of the motor housing 1 is fixedly connected to the guide web ring 5. This fixes the outer blade 4 and the turbocharger blade 2 and guides the airflow.

[0026] The outer blades 4 and the turbocharger blades 2 are evenly spaced apart along the circumference of the motor housing 1 .

[0027] The guide web ring 5 is a flat ring structure.

[0028] The turbocharger blades 2, the fixing ring 3, the outer blades 4 and the guide web ring 5 are an integrally formed structure and can be integrally formed on the outside of the motor housing 1 by in-mold injection molding.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
