Abstract
The utility model relates to a fan set that is used for an automobile generator rotor, which comprises a front fan and a rear fan, wherein, the front fan is installed on the outer end surface of a forpaw pole of the generator rotor, and the rear fan is installed on the outer end surface of a rear-paw pole of the generator rotor; an opening is arranged between two blades on the front fan, and the opening is arranged to correspond to the root part of two paws of the forpaw pole, and the shape of the opening is consistent with a transitional arc at the root of two paws of the forpaw pole. Only the front fan has the opening structure, and the shape and the position of the opening are just matched with the transitional place at two root parts of the paw pole, and the rear fan is free from the above opening, so that the blades of the front fan form a high wind pressure area, and the end surface of the rear fan forms a low wind pressure area; when the air flows from the high wind pressure area to the low wind pressure area of the rear fan through the gap between the paw poles, the heat of the magnetic winding can be rapidly brought away; moreover, the blades of the fan present in a curved surface structure, so that the air flows in a curved-line movement way along with the surface of the blade, thereby forming a vortex between two blades, thereby increasing the flowing energy of the air.
Description
Technical field
The utility model relates to a kind of fan group that is used for generator amature, especially a kind of fan group that is used for automobile generator rotor.
Background technology
Parts in the automobile current generator, all can pass through to produce a large amount of heats as magnetic field winding, stator coil, rectifier stack, brush, voltage regulator and slip ring assembly etc. owing to what electric current or magnetic field arranged, if these heats can not effectively be subdued discharge, will damage foregoing circuit and magnetic circuit element, finally cause generator not generate electricity, the life-span reduces.
In order to solve the cooling heat dissipation problem of above-mentioned these parts, the Power generator fan design is one of focus of industry research always.The Hyundai Motor Power generator fan develops into built-in double fan from one-sided external fan gradually---and the outside of two pawl utmost points of rotor respectively fixedly mounts a fan, and the generator amature assembly places the generator ' s cover inboard, so form built-in double fans structure.The air channel of built-in fans is an air inlet through hollow shaft, radially air-out, though can the stator coil that produce the heat maximum directly be cooled off, relative with one-sided external fan, its cooled rotor limited in one's ability.At present, the general structure of the built-in double fan of generator as shown in Figure 1.To output 2, the rotor direction of rotation is a clockwise direction from drive end 1, and when rotor rotated, air flowed from high blast district to low blast district.But among Fig. 1,3 districts and 4 districts are high blast district, and 5 districts and 6 districts are low blast district, so air is difficult to flow in the gap of the two pawl utmost points, but directly from radially flowing out, though therefore can directly cool off stator coil, the radiating effect of magnetic field winding is with regard to variation.
