[0029] like Figure 1 and Figure 4 As shown, the embodiment of the utility model provides a motor ventilator base, including a motor base body 1 and a ventilation slot structure, a plurality of the ventilation slot structures are installed on the outer peripheral surface of the motor base body 1 and are distributed at intervals along the circumference of the motor base body 1, and a ventilation slot extending along the axial direction of the motor base body 1 is provided in the ventilation slot structure, and a ventilation duct 6 connected to the outside and used for conveying a refrigerant is provided in the ventilation slot;
[0030] A communication groove 12 is provided on the side wall of the motor base body 1 , and the hollow cavity 11 of the motor base body 1 is connected with the ventilation channel through the communication groove 12 .
[0031] It should be noted that, in order to better understand the present invention, in this embodiment, the refrigerant is taken as a cold air flow as an example for explanation. Of course, in some cases, the refrigerant can be a gaseous or liquid substance with a cooling and heat exchange effect, such as a coolant.
[0032] Optionally, the motor ventilator base 1 in the utility model is applied to a flameproof motor, so that the flameproof motor has a good heat dissipation effect while having a high-voltage explosion-proof effect. It should be further explained that in this embodiment, the motor base body 1 is made of high-strength gray cast iron material, which is the main material for manufacturing flameproof motors, so that the flameproof motor has the physical property of high-pressure resistance.
[0033] By setting up multiple ventilation slot structures, ventilation channels and ventilation ducts 6, and using the ventilation ducts 6 to input refrigerant, the heat generated by the heat-generating components inside the motor base body 1 enters the ventilation channels through the connecting slots and exchanges heat with the ventilation ducts 6 that transport the refrigerant, and further the heat inside the motor base body 1 is output after heat exchange with the refrigerant, thereby increasing the heat dissipation effect of the motor.
[0034] It should be further explained that the ventilation channel runs through the ventilation channel structure along the axial direction of the motor base body 1, and the ventilation duct 6 is arranged in the ventilation channel and is sealed and connected to the openings at both ends of the ventilation channel. There is a gap between adjacent ventilation ducts 6, so that the heat flow in the motor base body 1 can fully contact the ventilation duct 6 to ensure the heat exchange efficiency. Preferably, the sealed connection can be connected by expanding the pipe.
[0035] The multiple ventilation slot structures include two first ventilation slot structures 2 and two second ventilation slot structures 5, the two first ventilation slot structures 2 are arranged on both sides of the bottom of the motor base body 1, the second ventilation slot structures 5 are arranged on both sides of the top of the motor base body 1, and the number of ventilation ducts 6 of the first ventilation slot structure 2 is greater than the number of ventilation ducts 6 of the second ventilation slot structure 5.
[0036] Optionally, the area of the ventilation channel of the second ventilation channel structure 5 is 116 mm×45 mm, and the ventilation duct 6 can be a seamless steel pipe of φ20 mm×1.5 mm.
[0037] In this embodiment, nine ventilation ducts 6 are arranged in the ventilation duct of the first ventilation duct structure 2, and the two ends of the nine ventilation ducts 6 are respectively fixed to the two ends of the ventilation duct and form a state parallel to the axial direction of the motor base body 1. Further, two ventilation ducts 6 are arranged in the ventilation duct of the second ventilation duct structure 5, and the ventilation ducts 6 in the first ventilation duct structure 2 and the ventilation ducts 6 in the second ventilation duct structure 5 can adopt the same seamless steel pipe of φ20mm×1.5mm.
[0038] It should be noted that the hollow cavity 11 of the motor base body 1 is used to install the motor and the motor radiator, and the motor radiator is used to generate airflow to circulate the gas in the ventilation channel and the hollow cavity 11 .
[0039] Typically, the motor radiator is installed on the rear side of the motor base body 1 (in the positive direction of the Y axis), and the motor radiator works to blow cold air flow to the heat-generating components inside the motor base body 1. For example, the winding coil of the motor will generate a large amount of heat after being powered on, causing the temperature of the motor to rise. The heat of the heat-generating components inside the motor is dissipated by the cold air flow. At this time, the cold air flow will be exchanged with the heat of the heat-generating components inside the motor base body 1 to form a hot air flow, and the hot air flow fills the entire motor cavity 11 of the motor base body 1. The refrigerant is transported through multiple ventilation ducts 6. The refrigerant in this embodiment is a cold air flow. The continuous flow of the cold air flow keeps the ventilation duct 6 in a low temperature state. Since the motor cavity 11 is connected with the ventilation channels of the second ventilation slot structure 5 and the ventilation channels of the first ventilation slot structure 2 through the connecting groove 12, the hot air flow in the motor cavity 11 can enter the ventilation channels of the ventilation slot structure through the connecting groove 12, so that the hot air flow and the refrigerant can exchange heat. The arrangement of multiple ventilation ducts 6 can improve the heat exchange efficiency of the motor. At the same time, the wind resistance can be reduced in the process of the cold air flow passing through the motor base body 1 through the ventilation duct 6, thereby increasing the heat dissipation area and improving the heat dissipation efficiency.
[0040] Furthermore, since the direction of the cold air flow blown by the motor radiator is parallel to the direction of the ventilation channels of the second ventilation slot structure 5 and the ventilation channels of the first ventilation slot structure 2, after the hot air flow is formed, it can flow along the corresponding ventilation channels, so that the hot air flow and the cold air flow along the ventilation channels of the second ventilation slot structure 5 and the ventilation channels of the first ventilation slot structure 2 can accelerate the heat exchange efficiency.
[0041] It should be noted that the refrigerant can be replaced under certain conditions. For example, a pipe interface is set at the end of the ventilation duct 6, and connected to an external coolant circulation device through the pipe interface. Heat exchange between the coolant and the hot air flow in the motor cavity 11 can be realized to achieve the heat dissipation effect of the motor.
[0042] Furthermore, a connecting shell 3 is provided on the outer cover of the second ventilation slot structure 5, the inner cavity of the connecting shell 3 is connected to the ventilation slot of the second ventilation slot structure 5, the connecting shell 3 is provided with second air holes 32 at both ends along the axial direction of the motor base body 1, and a plurality of first air holes 31 are provided on the side of the connecting shell 3 away from the motor base body 1.
[0043] Specifically, the hot air flow fills the entire motor cavity 11. In order to enable the motor radiator to continuously transport cold air flow into the motor cavity 11, the hot air flow in the motor cavity 11 needs to be discharged. By setting the first air hole 31 and the second air hole 32, the hot air flow formed by the cold air flow blown by the motor radiator after heating can be discharged from the motor base body 1, and according to the physical principle of hot air rising, the hot air flow can be further discharged from the motor base body 1 through the first air hole 31 and the second air hole 32, so that the motor base body 1 can be continuously air-cooled to ensure the cooling effect of the motor.
[0044] Furthermore, a lifting eye hole 33 is provided at the top of the communicating housing 3. Since the explosion-proof motor is large in size and weight, by providing the lifting eye hole 33, during the transportation of the motor base body 1, the lifting eye nut can be installed in the lifting eye hole 33, so that the motor base body 1 can be conveniently connected to the external lifting equipment, which is beneficial to the lifting of the motor base body 1 and on-site centering.
[0045] In this embodiment, refer to Figure 4 As shown, the first ventilation slot structure 2 and the second ventilation slot structure 5 are distributed in a rectangular shape on the surface of the motor base body 1, so that the outer surface of the motor base body 1 is divided into a top, a waist and a bottom;
[0046] Reference Figure 4 As shown, the first ventilation slot structure 2 and the second ventilation slot structure 5 are respectively distributed on the upper and lower sides of the motor base body 1, so that the motor base body 1 is rectangular as a whole, which improves the stability of the motor base body 1, and at least two motor feet 13 are arranged on the first ventilation slot structure 2, and the motor feet 13 can be fixed to the outside of the first ventilation slot structure 2 by welding. At the same time, the motor feet 13 are symmetrically distributed and used to support the motor base body 1 to ensure the stability of the motor base body 1. It should be noted that the motor feet 13 are provided with mounting holes to facilitate the installation and fixation of the motor base body 1.
[0047] like Figure 1 and Figure 2 As shown, the communication grooves 12 are arranged at two ends of the motor base body 1 in the axial direction, and the communication grooves 12 are distributed along the circumferential direction of the motor base body 1 .
[0048] The connecting groove 12 is used to connect the motor cavity 11 of the motor base body 1 with the ventilation channel, so that the hot air flow can be introduced into the ventilation channel. The connecting grooves 12 are distributed circumferentially, so that the hot air flow can enter the ventilation channel through multiple connecting grooves 12, thereby increasing the circulation efficiency of the hot air flow and making the hot air flow evenly flow into the ventilation channel, thereby making the heat dissipation of the motor more uniform. The connecting grooves 12 are arranged at both ends of the motor base body 1 in the axial direction so that the hot air flow can be evenly distributed in the ventilation channel, so that the hot air flow can fully contact the ventilation duct.
[0049] Furthermore, the outer peripheral surface of the motor base body 1 is provided with cooling fins 4, and the cooling fins 4 are distributed in the parts of the outer peripheral surface of the motor base body 1 where the ventilation groove structure is not provided, and the cooling fins 4 located at the top, bottom and waist of the motor base body 1 are at least partially embedded in the outer surface of the motor base body 1; the cooling fins 4 at the top, bottom and waist of the motor base body 1 are distributed in an octagonal shape with uneven spacing.
[0050] Generally, the heat dissipation fin 4 is usually in the form of a sheet, one end of which extends into the motor cavity 11 of the motor base body 1, so that the hot air flow in the motor cavity 11 can directly pass through the heat dissipation fin 4 for heat dissipation treatment, greatly improving the heat dissipation effect of the motor. In this embodiment, 78 heat dissipation fins 4 are provided. They are distributed on the top, bottom and waist of the motor base body 1, improving the heat dissipation capacity of the motor base body 1, and at the same time, referring to Figure 4 As shown, the heat dissipation fins 4 are distributed in an octagonal shape along the circumference of the motor base body 1, and cooperate with the first ventilation slot structure 2 and the second ventilation slot structure 5 to make the motor base body 1 as a whole in a cubic shape, thereby improving its stability.
[0051] In addition, it should be noted that the heat dissipation fins 4 distributed on the top, bottom and waist of the motor base body 1 are arranged in parallel. For example, the heat dissipation fins 4 arranged on the top and bottom of the motor base body 1 are arranged vertically (arranged along the Z-axis direction), and the heat dissipation fins 4 located at the waist of the motor base body 1 are arranged horizontally (arranged along the Y-axis direction). The heat dissipation fins 4 are non-equidistantly distributed. Since the first ventilation slot structure 2 and the second ventilation slot structure 5 are arranged on the motor base body 1, the heat dissipation fins 4 are not arranged equidistantly along the circumference as in the traditional motor.
[0052] Optionally, a junction box opening 14 is provided at the top of the motor base body 1, and the junction box opening 14 is close to the end of the motor base body 1 for the motor shaft to extend. Usually, the junction box opening 14 is provided at the tail of the motor. In this embodiment, by providing the junction box opening 14 at the top of the motor base body 1, it is convenient to connect the motor, while avoiding affecting the heat dissipation of the heat dissipation fins 4.
[0053] Another embodiment of the present invention provides a motor, comprising the motor ventilator base as described above.
[0054] The beneficial effects of the motor in this embodiment relative to the prior art are the same as those of the above-mentioned motor ventilator base, which will not be described in detail here.
[0055] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
