TECHNICAL FIELD

[0001] The present invention relates to a motor and a cooling device, and more particularly to a motor and a cooling device capable of achieving large-area cooling effect and energy saving. BACKGROUND

[0002] Generally, a motor generates a large amount of heat during operation, which accumulates on the motor body and affects the operation efficiency of the motor. Therefore, manufacturers install heat sinks or cooling fans on the outside of the motor to dissipate heat from the motor.

[0003] However, the heat sinks of the prior art can only dissipate heat from the motor in a small area, and the heat dissipation effect is very limited. In addition, the cooling fans need power to operate, which consumes additional energy. Therefore, it is necessary to provide a new motor capable of achieving large-area cooling effect and energy saving effect. SUMMARY

[0004] The main purpose of the present invention is to provide a cooling device capable of achieving large-area cooling effect and energy saving.

[0005] To achieve the above purpose, the cooling device of the present invention is applied to a motor body of a motor and is used to contain a cooling liquid to cool the motor body. The cooling device comprises a cylindrical containing shell, an inlet and an outlet. The cylindrical containing shell is used to contain the motor body, and the cylindrical containing shell comprises an annular containing space and a top portion. The annular containing space contains the cooling liquid. The inlet is arranged on the top portion and communicates with the annular containing space. The inlet is used to allow the cooling liquid to flow into the annular containing space. The outlet is arranged on the top portion and communicates with the annular containing space. The outlet is used to allow the cooling liquid to flow out of the annular containing space.

[0006] According to an embodiment of the present invention, the cooling device further comprises at least one outlet guide strip, the at least one outlet guide strip surrounds the cylindrical containing shell and is close to the top portion, and the at least one outlet guide strip forms an outlet guide opening and an outlet guide water channel in the annular containing space, wherein the outlet guide water channel is in the shape of a circular arc.

[0007] According to an embodiment of the present invention, the outlet guide water channel communicates the outlet guide opening and the outlet.

[0008] According to an embodiment of the present invention, the outlet guide water channel is used to guide the cooling liquid flowing from the outlet guide opening to the outlet.

[0009] According to an embodiment of the present invention, the cooling device further comprises at least one inlet guide strip, the cylindrical containing shell comprises a long axis direction and an opening, wherein the motor body is contained in the cylindrical containing shell through the opening, the at least one inlet guide strip is connected to the cylindrical containing shell, and an inlet guide water channel is formed in the annular containing space, wherein the inlet guide water channel extends linearly along the long axis direction towards the opening.

[0010] According to an embodiment of the present application, the water inlet guide channel is connected to the water inlet.

[0011] According to an embodiment of the present application, the water inlet guide channel is used to guide the cooling liquid flowing from the water inlet to the bottom of the annular accommodation space.

[0012] According to an embodiment of the present application, the cooling device further comprises an upper cover covering the cylindrical accommodation shell.

[0013] According to an embodiment of the present application, the upper cover and the cylindrical accommodation shell are combined with each other in an integral molding manner.

[0014] Another main object of the present application is to provide a motor capable of achieving large-area cooling effect and energy saving.

[0015] To achieve the above objects, a motor according to the present application comprises a motor body and the cooling device as described above.

[0016] Through the design of the motor and the cooling device according to the present application, the large-area cooling effect can be achieved, and the motor does not need to be supplied with extra power, so that the energy saving effect can be achieved. In addition, through the design of the water channel of the motor, the temperature of the target heat area can be effectively removed, so that the water with higher temperature is raised to a high place and then effectively flows out to the outside. The motor is formed by a casting process, which can save the time and cost of separately manufacturing and welding the water flow channel, the upper cover and the cylindrical accommodation shell.

[0055] like Figures 1 to 3As shown, in an embodiment of the present application, the motor 200 can achieve large-area cooling effect and the motor 200 does not need additional power supply to achieve energy saving effect. The motor 200 includes a cooling device 1 and a motor body 210, the cooling device 1 contains a cooling liquid 100 to cool the motor body 210, and the motor 200 is, for example, a vacuum motor or a water pump motor. The cooling liquid 100 is, for example, water. The cooling device 1 includes a cylindrical containing shell 10, a water inlet 20, a water outlet 30, three water outlet guide strips 40, 40a, two water inlet guide strips 50, and an upper cover 60.

[0056] In an embodiment of the present application, the cylindrical containing shell 10 is used to contain the motor body 210, the cylindrical containing shell 10 includes an annular containing space 11, a top 12, an opening 13, an outer wall 14, and an inner wall 15, and the cylindrical containing shell 10 has a long axis direction F. The outer wall 14 and the inner wall 15 are both cylindrical shells, the inner wall 15 is located inside the outer wall 14, a layer is formed between the outer wall 14 and the inner wall 15, the annular containing space 11 contains the cooling liquid 100, and the annular containing space 11 is located in the layer between the outer wall 14 and the inner wall 15. The top 12 includes a top surface 121, which is a surface facing and contacting the upper cover 60. The motor body 210 is contained in the cylindrical containing shell 10 through the opening 13. Since the cylindrical containing shell 10 surrounds the motor body 210, the cooling liquid 100 in the annular containing space 11 will perform large-area heat exchange with the motor body 210 to achieve the purpose of cooling the motor 200.

[0057] In an embodiment of the present application, the water inlet 20 is arranged on the top 12 of the cylindrical containing shell 10 and communicates with the annular containing space 11, and the water inlet 20 is used to supply the cooling liquid 100 into the annular containing space 11.

[0058] In an embodiment of the present application, the water outlet 30 is arranged on the top 12 of the cylindrical containing shell 10 and communicates with the annular containing space 11, and the water outlet 30 is located beside the water inlet 20. The water outlet 30 is used to supply the cooling liquid 100 after absorbing heat out of the annular containing space 11. The water inlet 20 and the water outlet 30 are located at different levels, and compared with the water inlet 20, the water outlet 30 is closer to the top surface 121, that is, the height of the water outlet 30 is higher than that of the water inlet 20.

[0059] In an embodiment of the present application, three water outlet guide strips 40, 40a are arranged around the inner wall 15 of the cylindrical housing 10 and close to the top 12. One of the water outlet guide strips 40a is arranged at the uppermost position of the cylindrical housing 10, and the other two water outlet guide strips 40 are arranged below the water outlet guide strip 40a. A water outlet guide opening 41 is formed between the two water outlet guide strips 40. Two transversely extending water outlet guide channels 42 are formed between the water outlet guide strip 40a and the two water outlet guide strips 40, and the water outlet guide channels 42 are in the form of arcs between the outer wall 14 and the inner wall 15. One of the water outlet guide channels 42 is connected to the water outlet guide opening 41 and the water outlet 30, and is used to guide the cooling liquid 100 flowing from the water outlet guide opening 41 to the water outlet 30. However, the design of the water outlet structure of the present application is not limited to the above, for example, the number of the water outlets 30 can be changed to two, and the two water outlets 30 are arranged at the ends of the two water outlet guide channels 42, so as to improve the efficiency of the cooling liquid 100 flowing out of the water outlets 30 to the outside. In addition, the number of the water outlet guide strips is not limited to three, and can be changed to one according to the design.

[0060] In an embodiment of the present application, two water inlet guide strips 50 are connected to the inner wall 15 of the cylindrical housing 10, and form a longitudinally extending water inlet guide channel 51 in the annular accommodation space 11. The water inlet guide channel 51 extends linearly along the long axis direction F towards the opening 13. The water inlet guide channel 51 is connected to the water inlet 20. The water inlet guide channel 51 is used to guide the cooling liquid 100 flowing from the water inlet 20 to the bottom of the annular accommodation space 11, and when the cooling liquid 100 continuously flows to the bottom of the annular accommodation space 11, the water level of the cooling liquid 100 will continuously rise along the bottom wall of the annular accommodation space 11. The two water inlet guide strips 50 are respectively connected to the two water outlet guide strips 40. In addition, the number of the water inlet guide strips is not limited to two, and can be changed to one according to the design.

[0061] In an embodiment of the present application, the upper cover 60 covers the cylindrical housing 10. The upper cover 60 and the cylindrical housing 10 are combined with each other in an integral molding manner. The cylindrical housing 10, the annular accommodation space 11, the outer wall 14, the inner wall 15, the three water outlet guide strips 40, 40a, the two water inlet guide strips 50, and the upper cover 60 are formed by a casting process, which can save the time and cost of separately manufacturing and welding the water flow channels, the upper cover 60 and the cylindrical housing 10, and increase the large-capacity annular accommodation space 11 in the cylindrical housing 10, and form the water channels that can guide the cooling liquid 100.

[0062] As Figure 1 , Figure 2 and Figure 4As shown, when the user wants to use the cooling device 1 of the present application to cool the motor body 210, first, the user must put the cylindrical accommodating shell 10 on the motor body 210. Then, the user must inject the cooling liquid 100 from the water inlet 20 into the annular accommodating space 11, so that the cooling liquid 100 flows in the water inlet guide channel 51 to the bottom of the annular accommodating space 11 along the water inlet direction A. When the cooling liquid 100 flows to the bottom of the annular accommodating space 11, it will flow along the flow directions B and C to the left and right sides, respectively, along the bottom wall of the annular accommodating space 11, and the water level of the cooling liquid 100 will continue to rise along the bottom wall of the annular accommodating space 11.

[0063] As shown in Figure 1 , Figure 3 and Figure 4 , the cooling liquid 100 flowing along the flow directions B and C converges on the other side of the annular accommodating space 11, at which time the water level of the converging cooling liquid 100 gradually rises along the rising direction D; in this way, the water level of the rising cooling liquid 100 in the annular accommodating space 11 is higher than the motor body 210, so it can completely surround the motor body 210 and perform large-area heat exchange to achieve the purpose of cooling the motor 200.

[0064] As shown in Figure 2 , Figure 3 and Figure 5 , during the process of the water level of the converging cooling liquid 100 gradually rising along the rising direction D, the cooling liquid 100 gradually warms up by absorbing the heat emitted by the motor body 210; when the water level of the cooling liquid 100 rises to the water outlet guide opening 41, the cooling liquid 100 flows into the water outlet guide channel 42 and flows out to the outside along the water outlet direction E from the water outlet 30. Therefore, by the above-mentioned channel design, the temperature of the target hot zone (i.e., the location of the motor body 210) can be effectively removed, and the water with a higher temperature is raised to a high place and then effectively flows out to the outside through the water outlet guide channel 42.

[0065] By the design of the motor 200 of the present application, large-area cooling effect can be achieved, and the motor 200 does not need to be supplied with additional power, so energy-saving effect can be achieved. In addition, by the channel design of the motor 200, the temperature of the target hot zone can be effectively removed, and the water with a higher temperature is raised to a high place and then effectively flows out to the outside. The motor 200 is formed by a casting process, which can save time and cost for separately manufacturing and welding the water flow channel, the upper cover and the cylindrical accommodating shell.

[0066] The present application shows its characteristics different from the prior art in terms of purpose, means and effect. However, it should be noted that the above-mentioned embodiments are for the convenience of illustration, and the protection scope claimed by the present application should be subject to the description in the claims, and not limited to the above-mentioned embodiments.
