Description

Technical Field

[0001] The present invention relates to a motor and a cooling device, and particularly to a motor and a cooling device that can achieve large-area cooling effect and energy saving. Background Art

[0002] When a general motor operates, a large amount of heat is generated, and this heat accumulates on the motor body and affects the operating efficiency of the motor. Therefore, manufacturers will install heat sinks or cooling fans outside the motor to dissipate heat from the motor.

[0003] However, a general heat sink can only dissipate heat from a small area of the motor, and its heat dissipation effect is very limited; in addition, a cooling fan needs electricity to operate, so it will consume additional energy. Therefore, it is necessary to provide a new motor that can achieve large-area cooling effect and energy saving. Summary of the Invention

[0004] The main object of the present invention is to provide a cooling device that can achieve large-area cooling effect and energy saving.

[0005] To achieve the above object, a cooling device of the present invention is applied to a motor body of a motor and is used to accommodate a coolant to cool the motor body. The cooling device includes a cylindrical accommodating shell, a water inlet and a water outlet. The cylindrical accommodating shell is used to accommodate the motor body. The cylindrical accommodating shell includes an outer wall, an inner wall, an annular accommodating space and a top. The annular accommodating space accommodates the coolant, and the annular accommodating space is located between the outer wall and the inner wall. The water inlet is provided on the top and communicates with the annular accommodating space. The water inlet is used for the coolant to flow into the annular accommodating space. The water outlet is provided on the top and communicates with the annular accommodating space. The water outlet is used for the coolant to flow out of the annular accommodating space.

[0006] According to an embodiment of the present invention, the cooling device further includes at least one water outlet guiding strip. The at least one water outlet guiding strip surrounds the cylindrical accommodating shell and is close to the top, and the at least one water outlet guiding strip forms a water outlet guiding port and a water outlet guiding channel in the annular accommodating space, wherein the water outlet guiding channel is arc-shaped.

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

[0008] According to an embodiment of the present invention, the water outlet guiding channel is used to guide the coolant flowing in from the water outlet guiding port to the water outlet.

[0009] According to an embodiment of the present invention, the cooling device further includes at least one water inlet guiding strip. The cylindrical accommodating shell includes a major axis direction and an opening, wherein the motor main body is accommodated in the cylindrical accommodating shell through the opening. At least one water inlet guiding strip is connected to the cylindrical accommodating shell and forms a water inlet guiding water channel in the annular accommodating space, and the water inlet guiding water channel extends linearly along the major axis direction towards the opening.

[0010] According to an embodiment of the present invention, the water inlet guiding water channel communicates with the water inlet.

[0011] According to an embodiment of the present invention, the water inlet guiding water channel is used to guide the coolant flowing in from the water inlet to the bottom of the annular accommodating space.

[0012] According to an embodiment of the present invention, the cooling device further includes an upper cover, and the upper cover covers the cylindrical accommodating shell.

[0013] According to an embodiment of the present invention, the upper cover and the cylindrical accommodating shell are combined with each other in an integrally formed manner.

[0014] Another main object of the present invention is to provide a motor that can achieve large-area cooling effect and energy saving.

[0016] Through the design of the motor and the cooling device of the present invention, a large-area cooling effect can be achieved, and the motor does not need to be supplied with additional power, so the energy-saving effect can be achieved. In addition, the water channel design of the motor can effectively remove the temperature of the target hot area, allowing the water with a higher temperature to rise to a higher place and then effectively flow 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 accommodating shell.

[0049] Please refer to the following together Figures 1 to 5 Regarding the cooling device of an embodiment of the present invention.Figure 1 Schematic diagram of a motor and a cooling device according to an embodiment of the present invention; Figure 2 Partial sectional view of the front of a cooling device according to an embodiment of the present invention; Figure 3 Partial sectional view of the back of a cooling device according to an embodiment of the present invention; Figure 4 In an embodiment of the present invention, the cooling device is along Figure 1 Sectional view along the section line XX shown; Figure 5 In an embodiment of the present invention, the cooling device is along Figure 1 Sectional view along the section line YY shown.

[0050] As Figures 1 to 3 shown, in an embodiment of the present invention, the motor 200 can achieve a large-area cooling effect and an energy-saving effect. The motor 200 includes a cooling device 1 and a motor main body 210. The cooling device 1 is configured to accommodate a coolant 100 to cool the motor main body 210. The motor 200 is, for example, a vacuum motor or a pumping motor. The coolant 100 is, for example, water. The cooling device 1 includes a cylindrical housing 10, a water inlet 20, a water outlet 30, three water outlet guiding strips 40, 40a, two water inlet guiding strips 50, and an upper cover 60.

[0051] In an embodiment of the present invention, the cylindrical housing 10 is used to accommodate the motor main body 210. The cylindrical housing 10 includes an annular accommodation space 11, a top 12, an opening 13, an outer wall 14, and an inner wall 15. The cylindrical housing 10 has a long axis direction F. The annular accommodation space 11 accommodates the coolant 100, and the annular accommodation space 11 is located between the outer wall 14 and the inner wall 15. The top 12 includes a top surface 121, and the top surface 121 is the surface facing and contacting the upper cover 60. The motor main body 210 is accommodated in the cylindrical housing 10 through the opening 13. Since the cylindrical housing 10 surrounds the motor main body 210, the coolant 100 in the annular accommodation space 11 will perform large-area heat exchange on the motor main body 210 to achieve the purpose of cooling the motor 200.

[0052] In an embodiment of the present invention, the water inlet 20 is provided on the top 12 of the cylindrical housing 10 and communicates with the annular accommodation space 11. The water inlet 20 is used to supply the coolant 100 to flow into the annular accommodation space 11.

[0053] In an embodiment of the present invention, the water outlet 30 is provided on the top 12 of the cylindrical housing 10 and communicates with the annular accommodation space 11, and the water outlet 30 is located beside the water inlet 20. The water outlet 30 is used to supply the coolant 100 after absorbing heat to flow out of the annular accommodation space 11. The water inlet 20 and the water outlet 30 are at different horizontal 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.

[0054] In an embodiment of the present invention, three water outlet guiding strips 40, 40a surround the inner wall 15 of the cylindrical accommodating shell 10 and are close to the top 12. One of the water outlet guiding strips 40a is arranged at the uppermost part of the cylindrical accommodating shell 10, and the other two water outlet guiding strips 40 are arranged below the water outlet guiding strip 40a. A water outlet guiding opening 41 is formed between the two water outlet guiding strips 40. Between the water outlet guiding strip 40a and the two water outlet guiding strips 40, two laterally extending water outlet guiding channels 42 are respectively formed, and the water outlet guiding channels 42 are arc-shaped. One of the water outlet guiding channels 42 communicates with the water outlet guiding opening 41 and the water outlet 30, and this one water outlet guiding channel 42 is used to guide the coolant 100 flowing into from the water outlet guiding opening 41 to the water outlet 30. However, the design of the water outlet structure of the present invention is not limited to the above. For example, the number of the water outlets 30 can also be changed to two, and the two water outlets 30 are respectively arranged at the ends of the two water outlet guiding channels 42 to improve the efficiency of the coolant 100 flowing out from the water outlets 30 to the outside. In addition, the number of the water outlet guiding strips is not limited to three, and it can also be changed to one according to the design.

[0055] In an embodiment of the present invention, two water inlet guiding strips 50 are connected to the inner wall 15 of the cylindrical accommodating shell 10, and the two water inlet guiding strips 50 form a longitudinally extending water inlet guiding channel 51 in the annular accommodating space 11. The water inlet guiding channel 51 extends linearly along the long axis direction F towards the opening 13. The water inlet guiding channel 51 communicates with the water inlet 20. The water inlet guiding channel 51 is used to guide the coolant 100 flowing into from the water inlet 20 to the bottom of the annular accommodating space 11. The two water inlet guiding strips 50 are respectively connected to the two water outlet guiding strips 40. In addition, the number of the water inlet guiding strips is not limited to two, and it can also be changed to one according to the design.

[0056] In an embodiment of the present invention, the upper cover 60 covers the cylindrical accommodating shell 10. The upper cover 60 and the cylindrical accommodating shell 10 are integrally formed and combined with each other. The cylindrical accommodating shell 10, its annular accommodating space 11, outer wall 14, inner wall 15, three water outlet guiding strips 40, 40a, two water inlet guiding 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 accommodating shell 10, and increase a large-capacity annular accommodating space 11 in the cylindrical accommodating shell 10, and also form a water channel for guiding the coolant 100.

[0057] As Figure 1 、 Figure 2 and Figure 4As shown, when the user wants to use the cooling device 1 of the present invention to cool the motor main body 210, first, the user must cover the motor main body 210 with the cylindrical accommodating shell 10. Then, the user must inject the coolant 100 from the water inlet 20 into the annular accommodating space 11, so that the coolant 100 flows in the water inlet guiding water channel 51 along the water inlet direction A to the bottom of the annular accommodating space 11. When the coolant 100 flows to the bottom of the annular accommodating space 11, it will flow along the bottom wall surface of the annular accommodating space 11 to the left and right sides respectively along the flow directions B and C.

[0058] As Figure 1 , Figure 3 and Figure 4 shown, the coolant 100 flowing along the flow directions B and C will converge on the other side of the annular accommodating space 11. At this time, the converged coolant 100 will gradually rise along the rising direction D; in this way, the height of the rising coolant 100 in the annular accommodating space 11 will be higher than that of the motor main body 210, so it can completely surround the motor main body 210 and conduct large-area heat exchange to achieve the purpose of cooling the motor 200.

[0059] As Figure 2 , Figure 3 and Figure 5 shown, during the process that the converged coolant 100 gradually rises along the rising direction D, the coolant 100 will absorb the heat dissipated by the motor main body 210 and gradually heat up; when the coolant 100 rises to the water outlet guiding port 41, the coolant 100 will flow into the water outlet guiding water channel 42 and flow out to the outside from the water outlet 30 along the water outlet direction E. Therefore, through the above water channel design, the temperature of the target heat area (i.e., the location of the motor main body 210) can be effectively removed, and the warmer water can rise to a higher place and then effectively flow out to the outside through the water outlet guiding water channel 42.

[0060] With the design of the motor 200 of the present invention, large-area cooling effect can be achieved, and the motor 200 does not need to supply additional power, so energy-saving effect can be achieved. In addition, the water channel design of the motor 200 can effectively remove the temperature of the target heat area, and make the warmer water rise to a higher place and then effectively flow out to the outside. The motor 200 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 accommodating shell.

[0061] In terms of purpose, means and efficacy, the present invention shows features that are quite different from the prior art. It should be noted that the above-mentioned many embodiments are for the convenience of illustration, and the scope of protection claimed by the present invention should be subject to what is described in the claims, rather than being limited to the above embodiments.
