Problems solved by technology

[0002] As a common heat dissipation and cooling product, fans are widely used in household, travel, and various equipment. Large air volume is a common demand. At present, the method of increasing the motor power and fan speed is generally used to increase the air volume, or to increase the surface area of ​​the fan blades. Increase the air volume, but increasing the power will increase the heat dissipation requirements and weaken the cooling effect of the fan; the method of increasing the surface area of ​​the fan blades is limited by the use of space

specific Embodiment

[0064] The fan 10 of a specific embodiment of the present invention, such as figure 1 As shown, it includes an impeller 106 and a motor 104 that is coaxial with the impeller 106 and is connected to the impeller 106 through a mounting groove and a buckle; figure 2 and image 3 As shown, five blades 102 are also included, and one end of each blade 102 is connected with the outer wall of the impeller 106, and is uniformly distributed in a circumferential array of the impeller 106 with the axis of the impeller 106 as the center; the radius of the impeller 106 is the same as that of each blade 102 The ratio of the distance from the other end of the impeller 106 axis to 0.3; as Figure 4 to Figure 8 As shown, it also includes an air inlet cover 100 and an air outlet cover 108 fixedly connected with the air inlet cover 100. The impeller 106 and the blade 102 are arranged in the cover body formed by the air inlet cover 100 and the air outlet cover 108, wherein the air inlet cover 10...

Abstract

The invention provides a fan. The fan comprises an impeller, a motor and a plurality of blades, wherein the motor is coaxially connected with the impeller; and one end of each blade is connected with the outer wall of the impeller. The ratio of the distance between the other end of each blade and the axis of the impeller to the radius of the impeller is 0.28-0.32. By means of the technical scheme, the ratio of the distance between the edges of the blades and the axis to the radius of the impeller is optimized and limited, so that the size of the blades is in a limited space, the matching performance of the blade size and the impeller size is improved, and the gas through-flow capacity is effectively improved, that is, the ventilating capability of the fan is improved; and thus, the air volume is increased in the limited space, the space is saved, and the heat dissipation and cooling capability of the fan is improved.

Description

technical field [0001] The present invention relates to the technical field of fans, in particular to a fan. Background technique [0002] As a common heat dissipation and cooling product, fans are widely used in household, travel, and various equipment. Large air volume is a common demand. At present, the method of increasing the motor power and fan speed is generally used to increase the air volume, or to increase the surface area of ​​the fan blades. Increase the air volume, but increasing the power will increase the heat dissipation requirements and weaken the cooling effect of the fan; the method of increasing the surface area of ​​the fan blades is limited by the use of space. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] In view of this, the present invention provides a fan. [0005] In order to achieve the above object, the technical solution of the ...
