The invention relates to the field of fans, in particular to an efficient cooling fan impeller. The efficient cooling fan impeller comprises a heat conduction ring and an impeller body arranged in theheat conduction ring and rotationally connected with the heat conduction ring. The impeller body comprises an outer wheel and an inner wheel. A sealing groove is formed between the heat conduction ring and the outer wheel and is filled with heat conduction oil. Multiple cooling paddles are connected between the outer wheel and the inner wheel, the thickness of the side, connected with the outer wheel, of each cooling paddle is larger than that of the side, connected with the inner wheel, of the corresponding cooling paddle. The number and positions of the cooling paddles are in one-to-one correspondence to those of heat transfer stirring blocks. According to the efficient cooling fan impeller, the defects that in the prior art, a fan impeller has no cooling effect, and pipelines cannot becooled are overcome; split type design is adopted, heat in pipelines can be rapidly transmitted into the impeller to achieve efficient cooling, meanwhile, the rotating resistance of the impeller canbe reduced on the premise of guaranteeing efficient cooling, and running efficiency is effectively improved; and high sealing performance is achieved, and overflowing of the heat conduction oil is effectively avoided.
Description
technical field [0001] The invention relates to the field of fans, in particular to an impeller of a high-efficiency heat dissipation fan. Background technique [0002] The pipeline fan uses high-speed rotation to exert pressure on the gas, so as to achieve the function of conveying gas, so the pipeline fan is widely used in the industrial field. In some specific occasions in the industrial field, it is necessary to transport gas to high-temperature pipelines. Because high temperature will cause certain safety hazards to pipelines, it is necessary to consider the heat dissipation of pipelines under the premise of air supply. Existing fans in these high-temperature pipelines usually only passively dissipate heat from the pipeline through the air flow generated by the rotation of the impeller, but the heat dissipation effect of the impeller on the pipeline is not obvious. [0003] For example, the application number is a kind of axial fan impeller of CN03121464.9. The impell...
