The present invention relates to a heat radiating machine for a driving motor, particularly to a water cooling cavity for a driving motor of an electric automobile, which is used for the heat radiation and cooling of a driving motor of an electric automobile. The present invention is characterized in that a water cooling scheme is adopted; a water cooling cavity layer Qis positioned at the outer ring of the driving motor, a rotor Z is arranged in the center, and a ring of stator D is arranged in the middle. In the water cooling cavity, the inner ring layer of the water cooling cavity layer Q simultaneously is the outer ring layer the stator D of the driving motor; the water cooling cavity layer Q is composed of the inner ring layer 1, a middle water channel layer 2 and an outer ring shell layer 3.
Description
Technical field
The present invention relates to a kind of electronic product accessory, particularly a kind of driving motor for electric automobile water-cooled cavity that is specifically designed to.
Technical background
Fuel-engined vehicle all is global big problem to the exhaustion three big problems of ecological construction, environmental pollution and the petroleum-based energy of the earth.So countries in the world a spare no expense huge sum of money, competitively development was not only free from environmental pollution but also open up new forms of energy, to be charged as the electric automobile of the energy.At present, the employed driving motor for electric automobile in countries in the world is nothing more than direct current machine and AC permanent magnet synchronous motor.When drive motors in when acting work because the friction of electric current can constantly produce very big heat, so any drive motors no matter, its common feature and the technical difficulty that is difficult to overcome are exactly the problem of cooling.Though people design and have made the technical scheme of many heat radiations pointedly, the radiating ribs that is similar to radiator fin is arranged, add fan etc. as processing or device on shell, its performance is all very undesirable, thereby cause the motor heat load to increase the weight of the bad result who weakens with actuating force, directly influenced the vehicle performance of electric automobile.So forms such as no matter AC magnetoelectric machine, or reluctance motor are because the heat radiation cooling makes motor drive efficiency all undesirable.Both influence drive motors function performance problem, directly influenced the great technical barrier of electric automobile performance again.
Summary of the invention
The purpose of the invention is to disclose and a kind ofly can be used for any drive motors heat radiation cooling, particularly can be used for the driving motor for electric automobile water-cooled cavity that driving motor for electric automobile provides heat radiation and cooling effect.
In order to reach the technical scheme that the foregoing invention purpose taked be:
Abandon air-cooled existing scheme, adopt water-cooling pattern.
Water-cooled cavity layer Q is positioned at the drive motors outer ring, and the drive motors center is rotor Z, between the center of drive motors and the outer ring water-cooled cavity, is the sub-D of centre one delineation of drive motors.The inner layer 1 of water-cooled cavity layer Q also is the outer layer of drive motors stator D simultaneously.The outer layer of drive motors stator is the main thermal source that drive motors produces heat, as long as the cold and hot exchange of water exchanges hot water, the heat radiation cooling problem of whole motor can be readily solved.As shown in Figure 1.
Described water-cooled cavity layer Q is to be made of inner layer 1, internal water main layer 2 and outer ring shell 3.
Described cooling water cavity inner layer 1 also is the outer layer of drive motors stator simultaneously, is to form with aluminium alloy founding moulding process and metalworking; Described internal water main layer 2 is to twine water-cooled cavity inner layer 1 by spirality radiating ribs 2.1 to form, and also can form with 1 while of water-cooled cavity inner layer founding moulding process and metalworking; Described outer ring shell 3 is after covering on internal water main layer 2 by round casing, constitutes cooling water seal chamber 2.2; On the outer ring shell 3 at cooling water seal chamber two, have into, the external mouth 4 of a cooling water that goes out is communicated with cooling water seal chamber 2.2.As shown in Figure 1 and Figure 2.
Described spirality radiating ribs 2.1 resembles shape of threads and is wrapped in equably on the inner casing 1, and the muscle of spirality radiating ribs 2.1 determines the width of cooling water seal chamber 2.2 water channels apart from the distance size.As shown in Figure 2.
Operation principle of the present invention and advantage are:
1, because the internal layer of cooling water cavity is again the shell of whole motor stator, whole casing is cooled water channel around the water cavity parcel that forms.Cooling water circulates along spirality channel, and the heat that motor the is produced water that can be cooled efficiently, is equably taken away.The spirality water cavity has substituted the air-cooled radiating ribs of conventional motors shell, and radiating efficiency is very low.Have spiral water-cooled cavity radiating ribs but use the intermediate layer instead, with the shell of whole motor stator be one, three ring layers cooperate and form the circulating water cavity structure of spirality channel.So outer water flowing of heat of motor generation is after the spirality channel circulation is cooled off, and its cooling rate is high.Spiral heat dissipation muscle and external seal shell material adopt aluminium alloy casting, thereby alleviate complete machine weight.
2, variable-frequency motor can not surpass rated power operation usually, and rotating ratio is below 1: 3.And motor of the present invention has been owing to solved heat radiation cooling problem well, and maximum power can reach 3 times of rated power operations, and the rotating speed specific energy is more than 1: 5.And common electric machine is all in 1: 4.When the close design of stator magnet, general design of electrical motor is less than 1.7T, and this design of electrical motor is 2T, and enough mini-bus automobiles use, and general car is more than sufficient especially.This motor kilowatt weight is 1.8kg/kW, and common electric machine reaches 6kg/kW, therefore has only this motor to satisfy the technical requirement of electric automobile to drive motors fully.
The present invention can use in office what is the need for to dispel the heat the cooling motor on.
