Abstract
The utility model relates to an inner ventilation cooling system with a motor of a heat radiating structure, which belongs to the field of motor. A heat radiating fin structure of the motor is changed in shape and a centrifugal fan is arranged at the outer end of a motor shell, so that a special inner ventilation system is formed in the motor; a hollow heat radiating fin inner cooling structure is composed of 30 to 60 fins uniformly arranged circumferentially; two lateral sides of a cross section of each of the fins are designed to be in parallel, and the inner part of each of the fins is of a hollow design; and the heat radiating fins tightly cling to the motor shell in a mounting process and extend a certain axial length at two sides in the axial direction of the motor shell for mounting an end cover and the fan, so that better cooling effect can be realized. The inner ventilation cooling system with the motor of the heat radiating structure provided by the utility model is novel and simple in structure and convenient to realize, is favorable for improving the thermal performance of the motor and is of a certain guiding significance for the ventilation cooling effect of the large-capacity motor.
Description
Technical field
The utility model relates to the interior ventilation cooling system with radiator structure motor, belongs to machine field.
Background technology
In the motor that has the heat radiation fin structure type of cooling; Often the cooling fan with motor one end is positioned between electric motor end cap and the fan housing; Utilize the end centrifugal fan cooling air to be blasted on the open space on motor housing and heat radiation wing surface; But because the fan efficiency restriction of motor coaxle rotation and the difference of operating condition for than low capacity or the lower motor of heat load, possibly play a role.But,, often make this type of cooling not reach expected effect for the bigger motor of capacity.Particularly when the type motor moved, the air in the motor gas-gap did not almost produce axial flow, and the heat of rotor only is delivered on the motor stator with the conduction of air, was finally shed by casing and heat radiation wing, had caused the increase of temperature rise in the motor.
The utility model content
The purpose of the utility model provides a kind of more reasonable feasible hollow type heat radiation fin structure; Through changing motor radiating fin structure size; Can impel the cooling air of motor in motor gas-gap and hollow type heat radiation wing, to produce mobile; Form the inner-cooling structure of motor cooling, improve the cooling effect of motor.
The utility model technical solution is: hollow type heat radiation wing is from inner-cooling structure; By being installed in the stator cage outside; And along equally distributed 30～60 wings composition of circumference; Its inside is hollow design, and the heat radiation wing is close on the motor case when mounted, and the heat radiation wing stretches out certain axial length respectively in the axial both sides of motor case and is used to install end cap and fan.
The dual-side in the cross section of said heat radiation wing is parallel design.
The cross section of said heat radiation wing can be trapezoidal shape, and promptly the excircle of each wing and inner periphery are trapezoidal last base and bottom, and both sides are trapezoidal waist.
Said heat radiation wing is made up of the metal with certain intensity, and each wing has identical thickness and axial length, closed at both ends, and the axial length that stretches out at the motor case two ends is 3 to 2 at the length ratio near a side of fan end and opposite side.
In addition, the casing of described heat radiation wing and motor can integratedly be processed into overall structure.
The advantage of the utility model: the structure of motor housing and heat radiation wing is changed,, the centrifugal cooling fan of electric motor fan end is moved within the electric motor end cap through extending axially of heat radiation wing.The rotating shaft rotation drives the operation of fan when utilizing the motor operation; Air in the motor gas-gap is got rid of in the heat radiation fin space of hollow; Form the interior ventilating system of drive of motor end-air gap-fan end-heat radiation wing inner chamber-driving end, improved the effect of motor ventilation cooling effectively.

Embodiment
Embodiment one: as shown in Figure 1, the heat radiation wing is the hollow type structure vertically, and closed at both ends along 30～60 wings that evenly distribute on the circumference, is 48 wings in the present embodiment.Each wing wall thickness of hollow type heat radiation wing is all identical, and is close to equably on the motor case circumference, and the parallel design of dual-side of each wing of heat radiation wing is as shown in Figure 2.Heat radiation wing outermost is close to motor case vertically, and the entire heat dissipation wing can be formed or cast by metal material by a sheet metal compacting.The heat radiation wing stretches out certain axial length respectively at an end and the casing other end (being also referred to as fan end) of motor case; Wherein be slightly larger than the axial extension elongation of opposite side in the extension elongation of installing centrifugal fan one end; Guarantee that casing and end cap can adopt screw to fix, both remain 3 to 2 at axial extension elongation.
In addition,, can the casing and the described heat radiation fin structure of motor be done as a whole processing, can improve the radiating efficiency of motor greatly as the preferred version of this execution mode.
Embodiment two: on the basis of embodiment one; Keep the thickness of hollow type heat radiation wing wall identical, the heat radiation wing is close on the casing circumference equably, and the axial, cross-sectional view of heat radiation wing is as shown in Figure 3; Each wing of heat radiation wing adopts trapezium structure; The cylindrical and the interior circle of wing of promptly dispelling the heat is respectively trapezoidal last base and bottom, and the both sides in cross section are trapezoidal waist, and the width of the interior round porch of heat radiation wing axial cross section is bigger; As shown in Figure 4, enclosed construction is adopted in the axial two sides of heat radiation wing.Being provided with of heat radiation wing axial length adopted the structure identical with embodiment one.This execution mode fan also should manufacture into centrifugal structure wide at the top and narrow at the bottom.
In addition,, can the casing and the described heat radiation fin structure of motor be done as a whole processing, can improve the radiating efficiency of motor greatly as the preferred version of this execution mode.
