Description
Technical field
The utility model relates to a kind of technology in car air-conditioner field, specifically a kind of optimization evaporation fan cooling is logical
The structure in road.
Background technology
With the raising of the progress and people's quality of life of automobile industry, there are more and more families to select comfort
High and space spaciousness SUV vehicles are as walking-replacing tool, therefore the commonly used of SUV will be as new development trend, this vehicle
The big power consumption of fuel consumption is high, wherein because the increase of air conditioning exhausting amount also increases energy consumption problem to vehicle.Existing frequently-used evaporation wind
Machine cooling channel structure cools down motor because that cannot make full use of cooling wind, leads to that there are about 30% or more electric energy to be lost.Needle
More air conditioning exhausting amounts are needed to SUV vehicles, then fan energy consumption will be increased, but the heat dissipation effect of motor cannot such as change
It is kind, motor reduced service life, maintenance cost will be caused to increase.
Utility model content
The utility model is directed to deficiencies of the prior art, proposes a kind of knot of optimization evaporation fan cooling duct
Structure, this design can not only reduce energy consumption of electrical machinery under the premise of can meeting promotion air quantity, while can also improve motor refrigerating function, prolong
Long motor service life reduces maintenance cost.
The utility model is achieved through the following technical solutions:
The utility model includes:Spiral case and motor cover board, wherein:Motor cover board upper end is equipped with sealing ring with motor contact position
And be interference fitted with motor wall, spiral case and motor cover intralamellar part form cooling channel structure;The entrance of the cooling channel structure is extremely
The minimum range of draught fan impeller is 40~50mm, and the width of entrance is 15~25mm, and the height that cooling wind enters motor bottom is
35~45mm.Cooling duct entry bottom is concordant with wheel bottom.
Technique effect
Compared with prior art, the utility model optimizes cooling channel structure, can effectively increase the cooling wind of motor
Amount reduces motor internal temperature and energy consumption, extends motor service life;By increasing a circle caulking gum in motor cover board
Structure further reduces the loss of cooling wind, and can play the cushioning effect of protection motor.

Specific implementation mode
As shown in Figure 1, the present embodiment includes:Spiral case 1 and motor cover board 2, wherein:2 upper end of motor cover board is contacted with motor 5
Place is interference fitted equipped with sealing ring 3 and with 5 wall of motor, and cooling channel structure 4 is formed between spiral case 1 and motor cover board 2.
As shown in Fig. 2, the impeller used in the present embodiment has following size:H0For impeller height, H1For cooling vent height
It spends, then H1≈2/3H0, work as L1For the minimum range of impeller to entrance, then L1=40~50mm, the width L of entrance2=15~
The entry bottom of 25mm, cooling channel structure 4 are concordant with wheel bottom, and the height that cooling wind enters motor bottom is H2, H2=
35~45mm.
The sealing ring 3 is EPDM materials, and shore hardness is 30~45 degree, is had when coordinating with motor 5 certain
Decrement.
The entrance of the cooling channel structure 4 is located at the higher-pressure region of 5 outlet air of wind turbine, before not influencing air-conditioning total blast volume
It puts, some more wind is smooth into wind turbine cooling duct.
As shown in Fig. 5~Fig. 7, by verification experimental verification, the cooling duct can make motor being averaged in busy hour
Temperature rise value is down to 85 DEG C from 110 DEG C, effectively reduces the internal temperature of wind turbine, reduces energy consumption, and extend its service life.
When electrical power, motor shaft rotation drives flabellum rotation, the wind generated at this time to have under the promotion of wind pressure on a small quantity
Into the cooling duct of spiral case 1 and motor cover board 2, cooling wind enters motor bottom along cooling duct, under the action of negative pressure,
The bottom-up flowing of cooling wind, while exchanging heat with elements such as the brush of high temperature, coils, to which the heat of motor be taken away,
Reduce motor temperature.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the utility model principle and objective with
Different modes carries out it local directed complete set, and the scope of protection of the utility model is subject to claims and not by above-mentioned specific
Implementation is limited, and each implementation within its scope is by the constraint of the utility model.
