Abstract

The invention relates to a heat dissipation device for an automobile engine, which includes a fan (1), a heat exchanger (2), the fan is located on one side of the heat exchanger, and the fan includes a hub (4), main blades (3), a rotating shaft ( 5), the main blade is a twisted three-dimensional blade, the radial outer width of the main blade is greater than its radial inner width, the main blade includes a plurality of first blades (35), a plurality of second blades (36), the first blade, The second blades are arranged at intervals along the circumference; on the circumference of the same radial dimension, the width S1 of the first blade is greater than the width S2 of the second blade, which is characterized in that: the tops (33) of the first blade 35 and the second blade 36 are set There are auxiliary blades (37), and the thickness of the auxiliary blades along the rotation direction R of the fan is variable. It can effectively increase the air volume of the fan, change the pressure distribution between the main blades, make the pressure distribution more uniform, reduce the turbulent flow at the top of the blade, and improve the pressure distribution on the pressure surface and the negative pressure surface of the blade.

Description

technical field [0001] The invention relates to the field of heat dissipation of automobile engines, in particular to a heat dissipation device for automobile engines. Background technique [0002] The heat dissipation device of the automobile engine includes a fan and a heat exchanger. The existing heat dissipation device has the problems of small air volume of the fan, uneven pressure distribution, and vortex at the top of the blade. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a cooling device for automobile engines, which aims to effectively increase the air volume of the fan, change the pressure distribution between the main blades, make the pressure distribution more uniform, and reduce the pressure on the top of the blades. Turbulent flow, improving the pressure distribution on the pressure surface and negative pressure surface of the blade. [0004] In order to achieve the abov...
