Description

Technical Field

[0001] This utility model belongs to the field of encoders, and specifically relates to an integrated cooling fan motor. Background Technology

[0002] During the operation of an electric motor, heat dissipation is always a key factor affecting its performance, reliability, and service life. Traditional motor cooling methods often use external fans, which are installed outside the motor. The fan's rotation drives airflow to cool the motor.

[0003] However, this external fan cooling method has many drawbacks.

[0004] On the one hand, in many application scenarios with strict requirements for space layout, the additional space occupation may lead to difficulties in the overall layout of the equipment, or even fail to meet the actual installation needs.

[0005] On the other hand, the cooling efficiency of external fans has limitations. The airflow generated by the fan often blows across the outer surface of the motor, making it difficult to directly reach the areas inside the motor where heat is most concentrated, such as the stator windings and rotor core. The process of transferring heat from inside the motor to the casing and then dissipating it through the external fan involves significant thermal resistance, resulting in slow heat dissipation. Utility Model Content

[0006] The integrated cooling fan motor provided by this utility model can effectively solve the problems in the background art.

[0007] This utility model provides an integrated cooling fan motor, comprising:

[0008] The motor housing has a first air inlet and a second air inlet on its side wall;

[0009] And a fan fixed to the side wall of the motor housing to allow gas to flow in and out through the first and second air inlets.

[0010] As a further optimization of this utility model, the fan is fixed to the inner wall of the motor housing.

[0011] As a further optimization of this utility model, it also includes a mounting bracket fixed on the inner wall of the motor housing, and the fan is mounted on the mounting bracket.

[0012] As a further optimization of this utility model, the mounting bracket is provided with a mounting hole corresponding to the first air outlet, and the fan is located in the mounting hole.

[0013] As a further optimization of this utility model, the mounting bracket and the motor housing clamp the fan in the middle for fixation.

[0014] As a further optimization of this utility model, the second air outlet is located on one or both sides of the first air outlet.

[0015] As a further optimization of this utility model, the mounting bracket is provided with a strip-shaped or mesh-shaped cover plate that covers the second air vent.

[0016] As a further optimization of this utility model, the mounting bracket has a protrusion on the side facing the inner wall of the motor housing; the inner wall of the motor housing has a groove corresponding to the protrusion.

[0017] As a further optimization of this utility model, the fan is circular; the first air vent is circular, and the second air vent is oval.

[0018] As a further optimization of this utility model, the first air inlet and the second air inlet are provided in two sets and are located on opposite sides of the motor housing, respectively.

[0019] This utility model provides an integrated cooling fan motor that assembles the fan and motor housing into a single unit. The fan directly faces the rotor and stator in the radial direction of the motor shaft to achieve the exchange of hot and cold air. The fan is as close to the heat source as possible, shortening the airflow in and out travel distance, which can significantly improve the heat dissipation effect of the motor.

[0024] The components include: motor housing 1, first air vent 1a, second air vent 1b, groove 1c, fan 2, mounting bracket 3, mounting hole 3a, cover plate 3b, protrusion 3c, and stop block 3d. Detailed Implementation

[0025] like Figure 1-4 As shown, this embodiment includes a motor housing 1 and a fan 2.

[0026] The motor housing 1 has a first air vent 1a and a second air vent 1b on its side wall.

[0027] In this embodiment, the first air vent 1a is circular, and the second air vent 1b is a vertical oval hole. There are two second air vents 1b, symmetrically distributed on both sides of the first air vent 1a. In other embodiments, the first air vent 1a and the second air vent 1b can also adopt any other arbitrary shape. In yet another embodiment, the number of second air vents 1b can be set to one or three, or other numbers, and their positions can be set according to actual needs.

[0028] In this embodiment, the fan 2 is also circular, corresponding to the first air vent 1a.

[0029] To secure the fan 2, this embodiment also includes a mounting bracket 3, which is fixed to the inner wall of the motor housing 1 with screws. In other embodiments, the fan 2 can also be directly fixed to the side wall of the motor housing 1.

[0030] Corresponding to the first air outlet 1a, a circular mounting hole 3a is provided in the middle of the mounting bracket 3, and the fan 2 is located in the mounting hole 3a. Specifically, the diameter of the mounting hole 3a is slightly larger than the diameter of the fan 2, and a stop 3d is provided on the inward end face of the mounting hole 3a, so that the fan 2 can be inserted into the mounting hole 3a from the outside and then blocked by the stop 3d.

[0031] The diameter of the first air vent 1a is slightly smaller than the diameter of the fan 2, so that the fan 2 can be fixed in place by the mounting bracket 3 and the motor housing 1. This structure can fix the fan 2 without the use of any screws or snap-fit ​​structures.

[0032] The mounting bracket 3 has cover plates 3b on both sides, which cover the second air vent 1b. The cover plates 3b have a number of spaced ribs corresponding to the second air vent 1b. In other embodiments, they can also be set as mesh ribs. The cover plates 3b can prevent fingers, sticks, etc. from entering the motor through the second air vent 1b, while not affecting the airflow.

[0033] To facilitate the installation and positioning of the mounting bracket 3, in this embodiment, the middle part of the mounting bracket 3 with the mounting hole 3a protrudes slightly outward from the cover plate 3b to form a protrusion 3c. The protrusion 3c is generally quadrilateral. At the same time, a groove 1c is provided on the inner side wall of the motor housing 1 corresponding to the protrusion 3c. During installation, the protrusion 3c is inserted into the groove 1c to restrict the movement of the mounting bracket 3. At this time, the positions of the screw holes of the motor housing 1 and the mounting bracket 3 correspond to each other, and the mounting bracket 3 can be installed by simply inserting screws.

[0034] Preferably, in this embodiment, the first air vent 1a and the second air vent 1b are provided in two sets and are located on opposite sides of the motor housing 1, which can improve the heat dissipation effect.

[0035] In this embodiment, whether the fan 2 is an intake fan or an exhaust fan, it can enable the first air vent 1a and the second air vent 1b to flow in and out of the air, thereby bringing in cooler airflow from the outside and carrying away the heat inside the motor, thus achieving the heat dissipation function.

[0036] The structure in this embodiment allows the fan 2 to be as close as possible to the stator or rotor, which is especially beneficial for motors where the rotor is mounted outside the stator, providing excellent heat dissipation. Furthermore, when the motor rotates, the airflow paths formed by the first vent 1a and the second vent 1b are very short, effectively reducing airflow velocity loss and significantly improving heat dissipation.

[0037] It should be noted that the descriptions of directions such as up, down, left, right, front, back, top, bottom, inside, outside, horizontal, and vertical in this application are all based on the accompanying drawings in the specification and are intended to clearly express the technical solution, not to limit the scope of protection.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
