Abstract
The invention discloses a cooling method for the motor of a cross-flow fan, which is characterized in that: the motor is arranged in a housing with an opening; a cross-flow wind wheel is connected with both ends of the output shaft of the motor; a plurality of blades are arranged on the cross-flow wind wheel which is driven to rotate at high speed by the motor arranged in the housing with the opening; the blades drive the air to blow towards the motor to cool the motor. The invention has the advantages of improving cooling efficiency of the motor of the cross-flow fan by 2 to 4 times through the method that the blades arranged in the cross-flow wind wheel drive the air to cool the motor, lowering temperature rise of the motor by 20 to 80 K and enabling the motor of the cross-flow fan with compact size and high power.
Description
Technical field
The present invention relates to a kind of motor cooling means, relate in particular to a kind of motor cooling means for cross flow fan, belong to the thermal power field of engineering technology.
Background technology
The wind direction of cross flow fan is without motor, and the heat radiation of motor relies on free convection to dispel the heat mostly, so often volume is bigger for the motor of cross flow fan, power is less.The size impact of the motor of cross flow fan the size of entire equipment, and cross flow fan often is installed in less relatively place, space.The problem of temperature rise of motor limits dwindling of power of motor increase and size always, the problem of temperature rise that solves motor must be by the forced-convection heat transfer mode, the forced-convection heat transfer ability generally than the high 3-5 of heat transfer free convection doubly, the forced-convection heat transfer mode of motor is to increase fan or increase fin to solve the problem of temperature rise of motor at motor internal mostly, increases fan like this or increase the increase that fin can cause motor volume in motor.
Summary of the invention
Technical problem to be solved by this invention is the problem that can solve its temperature rise under the situation that does not increase the cross flow fan volume again.
Technical scheme of the present invention is: a kind of motor cooling means for cross flow fan, it is characterized in that, motor is placed a shell that has mouth, the shaft two ends of described motor are connected with tubular wine wheel, be equipped with blade on the described tubular wine wheel, the motor that tubular wine wheel is placed in the shell that has mouth drags high speed rotating, and blade drives wind to motor, sends a telegraph the machine cooling.
Beneficial effect of the present invention: the method that is equipped with blade drive air cooling motor by tubular wine wheel makes cross flow fan motor cooling effectiveness improve 2-4 doubly, and electric machine temperature rise can reduce 20-80K, makes the cross flow fan motor can accomplish that volume is little, and power is big.
Description of drawings
Fig. 1 is a motor cooling means for cross flow fan schematic diagram of the present invention.
Embodiment
The invention will be further described in conjunction with the accompanying drawings, by shown in Figure 1, the cross flow fan motor comprises tubular wine wheel 2 and motor 3, the characteristics of motor cooling means for cross flow fan of the present invention are motor 3 to be placed a shell 4 that has mouth, the shaft two ends connection tubular wine wheel 2 of described motor 3, be equipped with blade 1 on the described tubular wine wheel 2, the motors 3 that tubular wine wheel 2 is placed in the shell 4 that has mouth drag high speed rotating, and blade 1 drives wind to motor 3, send a telegraph machine 3 coolings.
