Description

Technical Field

[0001] The utility model relates to the technical field of motor heat dissipation, in particular to a guide cover used for motor heat dissipation. Background Art

[0002] The heat generated by the motor during operation, especially in high temperature environments in summer, may cause the motor to overheat or even burn out, causing damage to the equipment. Traditional motor cooling methods mainly rely on the motor's own cooling fan, but this method has limited cooling capacity and insufficient efficiency, making it difficult to meet the needs of use in high temperature environments.

[0003] The cooling fan that comes with the motor is located in a cover-type air duct and is installed at the tail of the motor. When the motor shaft rotates, it drives the fan blades installed on the shaft to rotate. The air flow generated by the rotation of the fan blades covers the outer surface of the motor to dissipate the heat from the heat dissipation strips on the motor. However, the cooling capacity of this air duct is also limited. It can only achieve cooling by driving the air circulation at the tail of the motor. When the airflow flows to the front end of the motor (the output end of the shaft), the airflow movement speed decreases, resulting in the heat generated at the front end of the motor cannot be quickly discharged, which in turn leads to insufficient overall heat dissipation capacity of the motor, which cannot meet current usage requirements. Summary of the invention

[0004] The utility model provides a guide cover for motor heat dissipation to solve the problem that the airflow circulation at the rear of the motor has little heat dissipation effect on the front end of the motor, which can improve the overall heat dissipation effect of the motor.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] A deflector for heat dissipation of a motor comprises a motor body, wherein the head end and the tail end of the rotating shaft of the motor body both extend out of the motor body, and further comprises a cover body 1 and a cover body 2, wherein the closed end of the cover body 1 is evenly distributed with air inlet holes, the cover body 1 covers the outside of the tail end of the rotating shaft, and the open end is fixedly connected to the motor body, the rotating shaft in the cover body 1 is arrayed with fan blades, the head and tail parts of the motor body are both covered with cover body 2, the cover body 2 is a hollow frustum with a small opening at one end and a large opening at the other end, the two small ends of the two cover bodies are relatively connected, the inner wall of the two large ends of each cover body is connected to the motor body via a connecting rod, and each cover body 2 is arrayed with a plurality of air outlet hole groups, the outer walls of the two large ends of the two cover bodies are connected via a connecting tube, and the connecting tube and the cover body 1 are connected via a plurality of connecting tubes.

[0007] Furthermore, the outer surface of the motor body is arrayed with heat dissipation strips, the inner wall of the small end of each cover body is fixedly connected to the heat dissipation strips, and there is a spacing between one end of each heat dissipation strip and the connecting rod on the same side, and there is a spacing between the other end and the connecting rod on the same side.

[0008] Furthermore, the sum of the lengths of the two cover bodies 2 is equal to the length of the motor body.

[0009] Furthermore, each of the air outlet holes groups on the cover body 2 is composed of a plurality of air outlet holes, and the plurality of air outlet holes are arranged at intervals along the length direction of the peripheral wall of the cover body 2.

[0010] Furthermore, each of the air outlet holes is a circular hole penetrating the inner and outer side walls of the second cover body, and the air outlet holes on the same air outlet hole group are perpendicular to the peripheral wall of the second cover body.

[0011] Furthermore, the plurality of connecting tubes are arranged in a circular array along the central axis of the connecting tube, one end of each connecting tube passes through a peripheral wall of the cover body to connect to an interior of the cover body, and the other end of the connecting tube passes through the middle of the peripheral wall of the connecting tube to connect to the interior of the connecting tube.

[0012] Furthermore, the cover body 2 is a hollow truncated cone made of silicon-aluminum alloy with openings at both ends, and the connecting rod is a round rod made of aluminum-silicon alloy.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] When the rotating shaft of the motor body rotates, the plurality of fan blades drive the airflow in the cover body one to enter the connecting tube through the connecting pipe, and the airflow in the connecting tube is blown toward the head and tail of the motor body through the air outlet holes on the two cover bodies two, so that the head and tail of the motor body are subjected to the same size of heat dissipation airflow, the heat dissipation of the motor body is uniform, and the heat dissipation capacity of the motor body is improved.

[0015] The airflow blown out of each air outlet on the cover body 2 of the utility model will flow toward the large end opening of the cover body 2, which can make the heat at the head and tail of the motor body flow out faster through the large end opening of the cover body 2 along with the air flow, further improving the heat dissipation capacity of the motor body.

The connecting tube 9 and the cover body 3 are connected through multiple connecting tubes 10, and the connecting tube 10 is a circular tube body made of iron. When the fan blades 6 rotate with the rotating shaft 2, the air in the cover body 3 enters the connecting tube 10.

[0023] The outer surface of the motor body 1 is arrayed with heat dissipation strips 11, which are long strips of rods made of silicon-aluminum alloy. The inner wall of the small end of each cover body 4 is fixedly connected to the heat dissipation strip 11, and there is a spacing between one end of each heat dissipation strip 11 and the connecting rod 7 on the same side, and there is a spacing between the other end and the connecting rod 7 on the same side.

[0024] The sum of the lengths of the two covers 4 is equal to the length of the motor body 1 .

[0025] The air outlet hole group on each of the second cover bodies 4 is composed of a plurality of air outlet holes 8 , and the plurality of air outlet holes 8 are arranged at intervals along the length direction of the peripheral wall of the second cover body 4 .

[0026] Each of the air outlet holes 8 is a circular hole penetrating through the inner and outer side walls of the second cover body 4 , and the air outlet holes 8 on the same air outlet hole group are perpendicular to the peripheral wall of the second cover body 4 .

[0027] The plurality of connecting tubes 10 are arranged in a circular array along the central axis of the connecting tube 9 , one end of each connecting tube 10 passes through the peripheral wall of the cover body 3 to connect to the interior of the cover body 3 , and the other end of the connecting tube 10 passes through the middle of the peripheral wall of the connecting tube 9 to connect to the interior of the connecting tube 9 .
