Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a centrifugal cooling fan structure for business machines, especially an innovative structural space type whose blades are unequally spaced. [Previous technology] According to the rapid development of information products, it has reached the point of generalization, making the requirements for products more and more high, especially in terms of sound requirements, from the average noise requirement to the stricter sound quality. In addition, office machines (such as computers, etc.) in the 0A office are more equipped with cooling fans to exclude hot air from the body. Among them, the fan blades arranged on the cooling fans are perpendicular to the fan wheels and work along the circumference. The state of the distance arrangement, by which the hot air is discharged from the body; however, this conventional structure still exists in actual use ^ The fan blade system of the pen fan is equally spaced, so it is The phenomenon that the energy of the sound obtained by the product of the frequency exists, causing the sound energy of this frequency to stand out next to the moon, so it forms an unpleasant sound, that is, the resonance noise f easily affects the life of the electronic components; when the When the frequency is equal to 7dB (decibel) of sound energy at adjacent frequencies, "this amount" needs to be further improved. 7 Meanings and explanations The new structure of the heat fan structure actually has the question of how to develop a more ideal and practical solution to the problems of the above-mentioned conventional business machines. [New content] M255650 4. Creation instructions (2) Technical problems to be solved ... The main fan, during the use of the fan, knows the heat dissipation of the transaction machine to improve the breakthrough. The industrial operation becomes annoying noise problems plus technical features to solve the problem. The hot air spinner and spacer ring are located outside the central spinner. The system includes a center-its technical characteristics are: the blades are Non-equidistant :: off: The unequal-distance configuration of the blade body blades is still =: self-set type 'but integral. Among the dynamic balance when the operation pattern is turned, these blades can be angles, and can also be the average score of the ring-shaped block: the non-equidistant configuration type is an asymmetric configuration type, and it has been set. Or construct a dynamic balance. Exactly the effect of counterweight technology with counterweight and weight reduction is mainly designed in the form of equidistant configuration, so that the fan blades are set to operate without the noise of the fan [reach improvement = = [implementation] In order to make Your reviewers have a better understanding of this creation & θ ^ ^, please here;: force = enough to describe as follows: Yue Yue "[Schematic and early explanation of the details] First of all, please refer to Section 1 ' P Pavilion-〆 上 ^ Centrifugal cooling fan blade configuration, d: Solid :: Creation = Fan (A 1) The large system includes a central = good solid: Example 'The hot air indigo seat (1 0) and Spacer ring
