[0035] As shown in Figures 1-4 The utility model discloses a kind of air duct plate structures 1, including plate body 11, plate body 11 is equipped with motor installation groove 112, plate body 11 includes oppositely arranged first end and second end, motor installation groove 112 is located at the first end of plate body 11 or the second end of plate body 11, the side wall of motor installation groove 112 is equipped with ventilation structure 111, ventilation structure 111 includes several through holes 1111, through hole 1111 is arranged along the thickness direction of the side wall of motor installation groove 112, forms the passage of air flow, the region of ventilation structure 111 corresponds to the position of motor installed in motor installation groove 112, so that the air current of entering through hole 1111 directly blows towards the motor installed in motor installation groove 112.

[0036] By opening such through hole 1111 structure on plate body 11, during motor operation, external air can directly blow towards motor through through hole 1111. Since through hole 1111 corresponds to the position of motor, the heat generated by motor can be quickly blown away by the air current entering through hole 1111. Compared with the traditional cold fan motor cooling mode, the traditional mode often relies on relatively closed air duct to indirectly cool, and the cooling efficiency is low. The ventilation structure 111 of the present application can make the air around the motor flow quickly and update, effectively reduce the temperature of the motor, improve the working stability and service life of the motor.

[0037] In addition, since the through hole 1111 is directly arranged on the plate body 11, there is no need to increase complex heat dissipation components such as complex heat dissipation fins, additional heat dissipation fans, and the like, and there is no need to use expensive materials such as special heat dissipation alloys. Only through simple processing of the plate body 11, such as drilling, milling, and the like, can the conventional mechanical processing technology be realized. Compared with the traditional heat dissipation improvement scheme, the cost is significantly reduced.

[0038] In an embodiment, the through hole 1111 is in a long strip shape. The long strip-shaped through hole 1111 has a unique technical advantage compared to other shapes (such as a circular shape), which increases the contact area and contact time of air and the motor. When the cooling fan is working, the airflow passes through the long strip-shaped through hole 1111, which can more effectively take away the heat generated during the operation of the motor, thereby reducing the temperature rise speed of the motor. In addition, in terms of processing and manufacturing, the processing of the long strip-shaped through hole 1111 is relatively more simple, which can improve production efficiency and reduce processing cost. For example, in batch production, the long strip-shaped through hole 1111 is processed by using an automatic milling device. Compared with the complex processing path required to process a circular through hole 1111 to achieve the same heat dissipation effect, the processing time can be shortened by about 20%-30%.

[0039] In an embodiment, a segmented long strip-shaped through hole 1111 is used. That is, instead of a complete long strip shape, it is composed of multiple shorter long strip segments. For example, for a long strip-shaped through hole 1111 originally designed to be 50 mm in length, it can be divided into 5 long strip segments of 10 mm in length, and the adjacent long strip segments are spaced apart by 2-3 mm. This design can ensure a certain ventilation effect while enhancing the structural strength of the side wall to some extent.

[0040] In an embodiment, a wave-shaped long strip-shaped through hole 1111 can also be used, which is similar to a sine wave or other wave curves. The wave-shaped design can increase the flow resistance variation of air in the through hole 1111, so that the airflow produces a certain turbulent effect, and enhances the heat exchange between the air and the surface of the motor.

[0041] In an embodiment, the through hole 1111 is arranged in the axial direction of the motor installed in the motor mounting groove 112.

[0042] The length of the through hole 1111 is adapted to the axial length of the motor, which can generally be 80%-95% of the axial length of the motor. For example, for a motor with an axial length of 40 mm, the length of the through hole 1111 can be set to be between 32-38 mm, so that the ventilation effect can be ensured while the structural integrity of the side wall is considered.

[0043] Since the through holes 1111 are consistent with the motor axis, air can flow along the main heat direction of the motor when passing through the through holes 1111, and has a larger contact area and contact time with the motor surface, thereby more effectively taking away heat. In addition, the through holes 1111 extending in the axial direction can guide the airflow to form a relatively regular flow direction, reduce airflow turbulence, reduce energy loss caused by airflow turbulence, and improve the overall heat dissipation efficiency. In addition, in terms of structural design, such a through hole 1111 layout is beneficial to optimizing the pressure distribution inside the air duct plate, making the ventilation process smoother, reducing the influence of local high or low air pressure on the ventilation effect, and thereby improving the overall performance and reliability of the cooling fan.

[0044] In an embodiment, an inclined through hole 1111 is arranged. That is, the through hole 1111 is not completely parallel to the motor axis, but forms a certain angle with the motor axis, such as 30°-60°. For example, in some special structure of the cooling fan, the installation position of the motor has a special angle relationship with the air duct, and the inclined through hole 1111 can better adapt to this structure, so that the airflow can blow to the motor surface at a more suitable angle, improving the heat dissipation effect.

[0045] In an embodiment, a plurality of through holes 1111 on the same ventilation structure 111 are arranged in uniform spacing and side by side. Since the through holes 1111 are uniformly distributed, the airflow can uniformly blow to each part of the motor surface, avoiding local overheating or poor heat dissipation. Moreover, the uniformly distributed through holes 1111 can make the stress on the side wall of the plate body 11 more evenly distributed, reducing the risk of structural damage caused by local stress concentration. In the long-term operation process, the plate body 11 of this structure can maintain good shape and performance stability, prolonging the service life of the plate body 11. At the same time, the uniform spacing design also facilitates quality control and standardized operation in the production process, improving production efficiency and reducing production cost.

[0046] In an embodiment, a plurality of through holes 1111 on the same ventilation structure 111 can be arranged in groups in uniform spacing. That is, a plurality of through holes 1111 are divided into a plurality of groups, and the through holes 1111 in each group are uniformly spaced, and the spacing distance between groups is greater than the spacing of the through holes 1111 in the group. For example, 20 through holes 1111 are divided into 4 groups, 5 in each group. The spacing of the through holes 1111 in the group is 5mm, and the spacing between the groups is 15mm. This design can enhance the ventilation effect in a specific area (such as the core area of the motor heat) on the basis of ensuring the overall uniform ventilation.

[0047] In an embodiment, a plurality of through holes 1111 on the same ventilation structure 111 are arranged in gradually changing spacing, that is, along a certain direction of the side wall of the motor mounting groove 112, the spacing of the through holes 1111 gradually increases or decreases.

[0048] It should be noted that, while meeting the good heat dissipation effect, the structural strength of the side wall provided with the ventilation structure 111 should also be considered, therefore, the impact resistance of the ventilation structure 111 area of the side wall provided with the ventilation structure 111 should be ensured to at least meet 0.5J.

[0049] In an embodiment, the motor mounting groove 112 includes a first side wall, a second side wall, a third side wall and a fourth side wall parallel to the axial direction of the motor mounted in the motor mounting groove 112, the first side wall, the second side wall, the third side wall and the fourth side wall form a square shape, and the ventilation structure 111 is arranged on at least one of the first side wall, the second side wall, the third side wall and the fourth side wall.

[0050] Specifically, the scheme of arranging the ventilation structure 111 on only one side wall has the advantages of simple structure and convenient processing. In some cold fan applications with relatively small motor heat and strict cost control, such design can meet the basic heat dissipation demand while reducing production cost and processing difficulty. Arranging the ventilation structure 111 on multiple side walls can significantly improve the heat dissipation efficiency. Through the ventilation cooperation of different side walls, multi-directional air flow is formed to dissipate heat from the motor, which can make the temperature distribution of the motor more uniform and reduce the risk of damage of the motor due to local overheating.

[0051] In an embodiment, the ventilation structure 111 is arranged on the interval side walls, that is, the first side wall and the fourth side wall or the second side wall and the third side wall are selected to arrange the ventilation structure 111. For example, in some cold fans with special air duct layout, such arrangement can better cooperate with the air flow direction of the overall air duct, so that the air flow entering the ventilation structure 111 forms a specific circulation path around the motor, improving the heat dissipation effect.

[0052] As shown in Figures 1-6 The utility model embodiment further provides a heat dissipation assembly, comprising the air duct plate structure 1, the motor is mounted in the motor mounting groove 112, and the motor is arranged at intervals with the side wall provided with the ventilation structure 111.

[0053] The existence of the interval space can form a relatively uniform air flow distribution around the motor after the air passes through the through hole 1111, avoiding the ventilation dead angle caused by the motor close to the side wall. At the same time, the interval arrangement is also beneficial to reduce the noise during the operation of the motor. When the motor is at a certain interval from the side wall, the energy of the motor vibration transmitted to the plate body 11 will be reduced, thereby reducing the noise generated by the vibration.

[0054] In an embodiment, the motor is spaced apart from the side wall on which the ventilation structure 111 is mounted by a distance of 5-10 mm. With such a design, the spacing range can ensure sufficient air flow around the motor to dissipate heat in time. At the same time, in terms of noise control, the spacing distance can effectively reduce the amplitude of the motor vibration transmitted to the air duct plate.

[0055] The utility model embodiment further provides a cold fan, including above-mentioned radiating assembly. In addition to above-mentioned radiating assembly, the rest structure of cold fan can be same with prior art, here the rest structure is not repeated.

[0056] The above is merely a specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the utility model, and these modifications or replacements should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
