Abstract
The utility model relates to an electric automobile air conditioning centrifugal fan, which comprises a mounting bottom plate, a volute, a double extended-shaft motor, an air inlet current collector and a wind wheel. The wind wheel is formed by axially splicing single wheels with two mutually stagger blades, and the blades are single-plate arc-shaped blades. When air flows through the impeller, higher pressure is generated, and the air inlet current collector can reduce air current perturbation. The electric automobile air conditioning centrifugal fan is small in appearance size, has higher wind pressure under a rated air quantity, further reduces noises generated by the air conditioning centrifugal fan, and improves sound quality of the air conditioning centrifugal fan.
Description
Technical field
The utility model relates to the car air conditioner supply air system, is specifically related to a kind of centrifugal blower that is used for the electric vehicle air-conditioning.
Background technique
According to country's 12 energy-conserving and environment-protective new energy development strategies, improve the severe form of the wasting of resources and scarcity of resources, national public transit system is dropped into research and development energetically and produces electric vehicle.
Traditional car air conditioner blower fan main body is main with plastics at present, and fan delivery is little, pressure is low, and one the used blower fan quantity of unit is many, noise is high, regulating power is poor, can not be applicable to the electric vehicle of new energy.
It is ZL200920044218.1 (notice of authorization number: CN201448256U that the patent No. is arranged; Notice of authorization day: on May 5th, 2010; Denomination of invention: the exhaust outlet to the blower fan body in the Chinese utility model patent a kind of air-conditioning centrifugal blower) improves, and the place is provided with porous slab at exhaust outlet, and the relative while with exhaust outlet of through hole is vertical with the airflow direction that exhaust outlet sends again; Reduce flow perturbation through through hole, reduce the noise that centrifugal blower sends.But along with the raising that the car load travelling comfort requires, this model utility can not satisfy the demands.Not only to further improve fan delivery and reduce performance such as noise, also will solve weight issue, satisfy the fire prevention of unit, requirement such as anticorrosion and anticreep again.
The model utility content
The purpose of the utility model is to overcome shortcoming of the prior art with not enough, and the electric vehicle air-conditioning that a kind of air quantity is big, noise is little centrifugal blower is provided.
The utility model is to realize through following technological scheme: a kind of electric vehicle air-conditioning centrifugal blower, and comprise base plate, spiral case, double extension shaft motor and wind wheel are installed, said wind wheel is formed by two axial continued accesses of single-wheel, and the blade of said two single-wheels staggers each other.And described blade is the veneer arc shaped blade.Described rotor diameter scope is 120mm-135mm.
Said spiral case also comprises the air inlet slip ring, and said air inlet slip ring adopts circular arc hole flanging shape, and said air inlet slip ring is fixedly mounted on the intake grill of spiral case.Described air inlet slip ring diameter range is 80mm-110mm.
Said installation base plate is provided with earth leakage protective device, and said earth leakage protective device comprises insulating bush and insulation board, is provided with insulation board between said double extension shaft motor and the installation base plate, and said insulating bush is sheathed on double extension shaft motor and the fixed connecting piece that base plate is installed.Said installation base plate cross section is a V-arrangement.
With respect to existing technology, the utility model is simple in structure, and boundary dimension is little, and the axial continued access of single-wheel of adopting two blades to stagger each other forms, and gas stream produce more high pressure, and the air inlet slip ring can reduce flow perturbation when impeller.Under nominal air delivery, have higher blast, also reduce the noise that the air-conditioning centrifugal blower sends, improve the sound quality of air-conditioning centrifugal blower.In addition, on the installation base plate, be provided with earth leakage protective device, move safer.
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Embodiment
Like Fig. 1 to a kind of electric vehicle air-conditioning of the utility model centrifugal blower shown in Figure 3; Comprise base plate 1, spiral case 2, double extension shaft motor 3, air inlet slip ring 5, wind wheel 4, link 6, reel 7 and earth leakage protective device are installed; Double extension shaft motor 3 and two spiral cases 2 are fixedly mounted on through socket head screw and install on the base plate 1, and two wind wheels 4 are fixed on spiral case 2 inside at motor double extension shaft two ends.
This installation base plate 1, spiral case 2, double extension shaft motor 3, air inlet slip ring 5, wind wheel 4 all adopt Carbon Steel Plate to be made, and spiral case 2 is designed to ultrathin spiral case 2.Not only light weight has also improved fire prevention, anti-corrosion function.
Base plate 1 is installed is provided with earth leakage protective device, this earth leakage protective device comprises insulating bush 8 and insulation board 9, be provided with insulation board 9 between double extension shaft motor 3 and the installation base plate 1, and insulating bush 8 is sheathed on double extension shaft motor 3 and the fixed connecting piece that base plate 1 is installed.The insulation board 9 that between double extension shaft motor 3 and installation base plate 1, is provided with plays anticreep second class protection effect with insulating bush 8.The cross section that base plate 1 is installed is a V-arrangement, above promptly motor is placed in be put down but the bottom make on the motor cabinet of V-type, spiral case is fixed on the plane that floor level is installed, and can save the space and strengthen installation base plate rigidity again.
Air inlet slip ring 5 is fixedly mounted on the intake grill of spiral case 2, and this air inlet slip ring 5 adopts slab circular arc hole flanging shape, and its diameter range is 80mm-110mm.
Wind wheel 4 is formed by the single-wheel 10 axial continued accesses that two blades 11 stagger each other, and this blade 11 adopts the veneer arc shaped blade.The motor double extension shaft passes the reel 7 at wind wheel 4 middle parts, is fixedly connected reel 7 and machine shaft through link 6, thereby is fixedly connected machine shaft and wind wheel 4.The diameter range of this wind wheel 4 is 120mm-135mm.
