Abstract

The utility model discloses an automotive electromagnetic fan clutch provided with a cyclone heat-dissipation device, which mainly comprises a fan fixing disk rotationally connected with a transmission shaft (5) by a bearing (8). The clutch is characterized in that a cyclone heat-dissipation flow channel (7) is formed by connecting bosses (9) distributed on the inner end face of a framework of the fan fixing disk with the end face of a permanent magnet fixing disk (4). When the clutch works, high-temperature heat accumulated in the fan fixing disk by heat conduction when a fan and the bearing work is quickly discharged outward in a rotational flow manner through spaced air inlets in the end face of the framework of the fan fixing disk, and through the cyclone heat-dissipation flow channel between the end faces of the fan fixing disk and the permanent magnet fixing disk, so that the working temperature of the fan fixing disk is reduced effectively. Compared with the prior art, the normal working temperature of the bearing is ensured; premature abrasion and destroy of and on the bearing are reduced obviously; the service life of the automotive electromagnetic fan clutch is prolonged effectively; and the use cost of a user is lowered effectively.

Description

Design of The Electromagnetic Fan-clutch with the cyclone heat dissipation device

(1) technical field: the utility model relates to the automobile fan engaging and disengaging gear; Be specifically related to a kind of Design of The Electromagnetic Fan-clutch with the cyclone heat dissipation device.

(2) background technique: Design of The Electromagnetic Fan-clutch in prior art, mainly comprise the drive plate that is connected on transmission shaft and the fan fixed disk that is rotatably connected with by bearing, be connected with magnet fixed disc at the semiclosed inner chamber ring set of described fan fixed disk.During work, distribute on resonator end surface in fan fixed disk and be connected with some block permanent magnets, the magnetic field suction that the soft magnet that is provided with in corresponding described magnet fixed disc end face produces, rotate by the fan on drive plate drive fan fixed tray, the high water temperature that is positioned at fan front end water tank is carried out cyclone heat dissipation.Its Shortcomings: the one, fan is in the outside suction heat of high temperature of cyclone heat dissipation, and the heat of high temperature that suction goes out is also being carried out high warm conduction to the front end of fan fixed disk and bearing; The 2nd, described bearing is everlasting during the high temperature of generation more than 85 degree in the work of running up.Because described fan fixed disk is semi-enclosed inner-cavity structure, the ventilation and heat cooling conditions is relatively poor, can not in time discharge by the heat of high temperature that fan and the conduction of bearing working heat are gathered, very easily cause the lubricant grease in bearing overflowed by the heat of high temperature dilution, the too early wearing and tearing that aggravated bearing damage.When the bearing wear breaking-up needs repairing replacing, garage's daily life of a family is because removing and installing inconvenience, the Design of The Electromagnetic Fan-clutch of integral body is done scrapped processing and renew separately, obviously reduced the working life of Design of The Electromagnetic Fan-clutch and increased user's user cost.

(3) summary of the invention: for the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of Design of The Electromagnetic Fan-clutch with the cyclone heat dissipation device, the user cost that is intended to improve its working life and reduces the user.

For achieving the above object, the technical solution of the utility model is achieved in that this Design of The Electromagnetic Fan-clutch with the cyclone heat dissipation device, mainly is included on transmission shaft and is rotatably connected with fan fixed disk by bearing; It is that the boss and the permanent magnet fixed tray end face that are distributed with on the skeleton interior edge face of described fan fixed disk connect and compose the cyclone heat dissipation runner.

When implementing technique scheme, the utility model is to be connected with cooling wind blade on the skeleton exterior edge face of described fan fixed disk, and the inner chamber ring set of described cooling wind blade is sealed in the outer end of described bearing.

The utility model is by taking said structure, in work, when fan carries out the outside suction heat of high temperature of cyclone heat dissipation to the high water temperature that is positioned at its front end water tank, conduct by fan and bearing working heat the heat of high temperature that accumulates in fan fixed disk, under the rotary work of fan and cooling wind blade, intake opening by interval on fan fixed disk skeleton end face, cyclone heat dissipation runner through between fan fixed disk and permanent magnet fixed tray both ends of the surface, outwards eddy flow is discharged fast, has effectively reduced the operating temperature of fan fixed disk.Be sealed in the outer end of bearing by the inner chamber ring set of cooling wind blade, fully isolated heat of high temperature that the fan work suction goes out to the heat conduction of bearing.Compare with prior art, guaranteed the normal working temperature of bearing, the too early wearing and tearing that reduced significantly bearing damage, and have effectively improved the working life of Design of The Electromagnetic Fan-clutch and have reduced user's user cost.

(4) description of drawings: Fig. 1 is a kind of embodiment's of the utility model sectional view;

Fig. 2 is the plan view of the utility model Fig. 1 fan fixed disk;

Fig. 3 be in the utility model Fig. 2 A-A to revolved sectional view.

(5) embodiment: Fig. 1 one is shown in Figure 3.This Design of The Electromagnetic Fan-clutch with the cyclone heat dissipation device mainly is included on transmission shaft 5 and is rotatably connected with fan fixed disk by bearing 8; Described fan fixed disk adopts the good aluminum alloy of heat-conductive characteristic to consist of usually.9 boss 9 (Fig. 2, shown in Figure 3) that are distributed with on the skeleton interior edge face of fan fixed disk connect and compose cyclone heat dissipation runner 7 (shown in Figure 1) with permanent magnet fixed tray 4 end faces.For increasing the cyclone heat dissipation effect and preventing that the external high temperature thermal source is to the heat conduction of bearing front end, usually be connected with cooling wind blade 1 on the skeleton exterior edge face of described fan fixed disk, the inner chamber ring set of described cooling wind blade is sealed in the outer end (shown in Figure 1) of described bearing 8.

The adpting flange of the utility model transmission shaft 5 is connected (shown in Figure 1) usually with auto pump.In work, when the high water temperature that is positioned at its front end water tank when 3 pairs, fan is carried out the outside suction heat of high temperature of cyclone heat dissipation, conduct by fan 3 and bearing 8 working heats the heat of high temperature that accumulates in fan fixed disk, under the rotary work of fan 3 and cooling wind blade 1, intake opening (shown in Figure 2) by interval on fan fixed disk skeleton end face, cyclone heat dissipation runner 7 (shown in Figure 1) through between fan fixed disk and permanent magnet fixed tray 4 both ends of the surface, outwards eddy flow is discharged fast, has effectively reduced the operating temperature of fan fixed disk.Be sealed in the outer end of bearing 8 by the inner chamber ring set of cooling wind blade 1, fully isolated heat of high temperature that the fan work suction goes out to the heat conduction of bearing, guaranteed the normal working temperature (shown in Figure 1) of bearing.

The above is only preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; other technical characteristics that need not just can associate through creative work; can also make modification and/or the improvement of several basic identical mode; realize essentially identical function and produce essentially identical effect; these variations should be considered as equivalent feature, within all belonging to the protection domain of the utility model patent.
