[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Motors usually have two application forms. The first is to convert mechanical energy into electrical energy, which is called a generator; the second is to convert electrical energy into mechanical energy, which is called an electric motor. A motor is a device that converts electrical energy into mechanical energy. As a power device, when current passes through the stator and rotor conductors, the conductors have resistance, which will generate heat and cause them to heat up.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a bearing adsorption component, the wind hood and the front end cover are placed in the second bracket and the first bracket respectively, and at this time, the wind hood, the front end cover and the outer shell are coaxial, and the second bracket and the first bracket are close to each other, and the wind hood and the front end cover are close to the end face of the outer shell, and then the wind hood and the front end cover are rotated under the action of the roller rod, so as to facilitate the alignment of the wind hood and the outer shell, and the installation holes on the front end cover and the outer shell, and the suction cups in the second bracket and the first bracket are fitted with the wind hood and the front end cover, and the suction of the negative pressure unit is used to make the suction cup generate negative pressure suction, compress the air inside the suction cup, so that its pressure drops, and then the wind hood and the front end cover are adsorbed, and then the second bracket and the first bracket continue to move close to each other, so that one end of the outer shell is clamped with the wind hood, and the other end of the outer shell is clamped with the front end cover, and then the connection parts of the wind hood, the front end cover and the outer shell are tightened, and during the installation process, there is no need to manually take and align the installation holes, which reduces the labor intensity and improves the installation efficiency; 2. The four edges of the base of the outer shell are respectively limited by the corresponding side blocks, that is, the edge of the base of the outer shell enters through the notch and reaches the top of the abutment block. Under the push of the inclined surface of the top of the abutment block, the abutment block moves toward the inner wall surface of the side block and causes elastic compression to the compression spring, so that the telescopic rod is shortened. The edge of the base is limited by the abutment block, and then the two-way screw rod 2 is driven to rotate by the handle 1, so that the two push plates are close to each other, and the push plates slide in the slide rail. The side of the push plate is limited to the end face of the base, so as to align and correct the installation position of the outer shell, ensure that the outer shell is always coaxial with the wind hood and the front cover when installed, and avoid installation errors; 3. By exchanging the inner flow tube and the outer flow tube, the inner flow tube is arranged at the lower part of the inner cavity of the outer shell, and the outer flow tube is arranged at the upper part and outside the inner cavity of the outer shell. When the water in the lower inner flow tube is heated, its density will decrease. Because the thermal expansion effect increases the distance between water molecules, the hot water with reduced density will be affected by the buoyancy of the colder and denser water in the upper outer flow tube, thereby rising from the return pipe 2 to the outer flow tube. At the same time, the colder water in the upper outer flow tube sinks to the lower inner flow tube through the return pipe 1 due to its high density, forming a circulation flow of cold and hot water, thereby completing heat exchange and improving the heat dissipation efficiency of the outer shell.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-Figure 6As shown, the present invention provides a heat dissipation type motor, including a bearing seat 1 and a motor body, the motor body including an outer shell 4, one side of the outer shell 4 is connected to a wind cover 3, and the other side of the outer shell 4 is connected to a front cover 2, the middle of the top surface of the bearing seat 1 is provided with a mounting groove 5 for mounting the outer shell 4, the inside of the mounting groove 5 is provided with an alignment adjustment component for positioning the outer shell 4, the middle of the upper surface of the bearing seat 1 is provided with an upwardly protruding sliding platform 9, the upper end of the sliding platform 9 is slidably installed with a bearing adsorption component, and the bearing adsorption component includes a bracket 2 10 and a bracket 1 1 that are close to or away from each other at the same time 3, the inner side surfaces of the second bracket 10 and the first bracket 13 are provided with an arc-shaped cavity for carrying and positioning the wind hood 3 and the front end cover 2, and a plurality of roller rods 16 are rotatably installed on the surface of the arc-shaped cavity, and the inner wall surfaces of the first bracket 13 and the second bracket 10 are both installed with suction cups 15, and the outer wall surfaces of the first bracket 13 and the second bracket 10 are installed with negative pressure units for vacuum adsorption of the suction cups 15. When in use, the base connected to the bottom of the outer shell 4 is placed into the mounting groove 5, and the outer shell 4 is aligned and limited by the alignment and adjustment component. Initially, the second bracket 10 and the first bracket 13 are located at the two side ends of the sliding platform 9, and then The wind hood 3 and the front end cover 2 are placed in the second bracket 10 and the first bracket 13 respectively, and at this time, the wind hood 3, the front end cover 2 and the outer shell 4 are coaxial, and the wind hood 3 and the front end cover 2 are close to the end surface of the outer shell 4 by the mutual approach of the second bracket 10 and the first bracket 13. Then, by moving the wind hood 3 and the front end cover 2, they are rotated under the action of the roller rod 16, so as to facilitate the alignment of the installation holes on the wind hood 3 and the outer shell 4 and the front end cover 2 and the outer shell 4, and the suction cups 15 in the second bracket 10 and the first bracket 13 are fitted with the wind hood 3 and the front end cover 2, and the suction of the negative pressure unit is utilized. The suction cup 15 generates negative pressure attraction, thereby adsorbing the wind hood 3 and the front end cover 2. After that, the bracket 2 10 and the bracket 1 13 continue to move closer, so that one side end of the outer shell 4 is clamped with the wind hood 3, and the other side end of the outer shell 4 is clamped with the front end cover 2. Then the connecting parts of the wind hood 3, the front end cover 2 and the outer shell 4 are tightened. During the installation process, there is no need to manually take and align the installation holes, which reduces the labor intensity and improves the installation efficiency. When the wind hood 3 and the front end cover 2 are removed for inspection, they are still supported by the bracket 2 10 and the bracket 1 13 to avoid falling during removal.

[0021] See also Figure 2 and Figure 4 As shown, the negative pressure unit includes an exhaust channel 12 connected to the suction cup 15, a piston member 23 is installed inside the exhaust channel 12, and the top end of the exhaust channel 12 is connected to an exhaust port 24, and a solenoid valve 25 is installed on the surface of the exhaust port 24; The piston member 23 includes a piston movable in the exhaust passage 12, and a rod body is provided at the end of the piston, and the piston is away from the exhaust port 24. When the suction cup 15 is in contact with the wind hood 3 and the front end cover 2, the piston member 23 is pulled outward, that is, the piston is pulled by the rod body to slide in the exhaust passage 12. Since the exhaust passage 12 is connected to the suction cup 15, the air in the suction cup 15 can be sucked out during vacuuming, and the air inside the suction cup 15 is compressed to reduce its pressure and be discharged from the exhaust port 24, thereby forming negative pressure adsorption, thereby adsorbing the wind hood 3 and the front end cover 2.

[0022] See also Figure 1 and Figure 2 As shown, a bidirectional screw 6 is rotatably installed inside the sliding platform 9, and the bidirectional screw 6 passes through the inside of the installation groove 5, and the bidirectional screw 6 is respectively threaded with a bracket 2 10 and a bracket 13, and the surfaces of the bracket 2 10 and the bracket 13 are penetrated with an arc groove 11, and a handle 2 8 is rotatably provided on the surface of one side of the bearing seat 1, and the rotating end of the handle 2 8 is fixed to the end of the bidirectional screw 6. When installing the base connected to the bottom of the outer shell 4, since the base extends to both sides, when it is installed in the installation groove 5, the bottom of the outer shell 4 does not contact the bidirectional screw 6, so it is convenient to drive the bidirectional screw 6 to rotate, and the arc groove 11 is used to tighten the installation holes of the wind cover 3 and the outer shell 4 and the front cover 2 and the outer shell 4, and the structural design is reasonable; A rotating shaft 17 protruding along the installation direction of the front end cover 2 is installed in the middle of the inner cavity of the outer shell 4, and a through groove 14 is provided on the top surface of the bracket 13 to fit with the rotating shaft 17. When the bracket 13 slides, the front end cover 2 is driven to pass through the rotating shaft 17, so that the rotating shaft 17 fits with the through groove 14, which is convenient for alignment and installation.

[0023] See also Figure 3 As shown, the alignment and adjustment component includes two push plates 19 arranged on the inner side of the installation groove 5. The two push plates 19 are arranged in parallel and approach or move away from each other at the same time. A side block 20 is fixed to the end of the inner wall surface of each push plate 19 for limiting the edge of the base connected to the bottom of the outer shell 4. The base connected to the bottom of the outer shell 4 is inserted into the installation groove 5, and the four edges of the base are respectively limited by the corresponding side blocks 20. Then, the two push plates 19 are brought close to each other to adjust the position of the base to ensure that the installation position of the outer shell 4 is always the same, thereby shortening the adjustment time.

[0024] See also Figure 3 and Figure 5As shown, the side block 20 is set to be L-shaped, and a notch 26 is provided at the upper edge end of the side block 20, and an abutment block 27 is provided inside the side block 20. The upper surface of the abutment block 27 is inclined outward and is in line with the inner wall surface of the notch 26, and the inner wall surface of the abutment block 27 is installed with a telescopic rod 28 fixedly connected to the inner wall surface of the side block 20, and the outer sleeve of the telescopic rod 28 is provided with a compression spring 29; the inner wall surface of one side of the mounting groove 5 is provided with a slide rail 21 that slides with the push plate 19, and the inner wall surface of the other side of the mounting groove 5 is rotatably installed with a two-way screw 18, and the two-way screw 18 is threadedly connected with the two push plates 19, and the front side surface of the bearing seat 1 is rotatably installed with a handle 7, and the rotating end of the handle 7 is connected to the end of the two-way screw 18 The bottom is fixed. When installing the base on the outer shell 4, the edge of the base enters through the notch 26 and reaches the top of the abutment block 27. Under the push of the top inclined surface of the abutment block 27, the abutment block 27 moves toward the inner wall surface of the side block 20, and causes elastic compression to the compression spring 29, so that the telescopic rod 28 is shortened. The edge of the base is limited by the abutment block 27, and then the two-way screw 18 is driven to rotate by the handle 1 7, so that the two push plates 19 are close to each other, and the push plates 19 slide in the slide rail 21. The side of the push plate 19 is limited to the end face of the base, so as to align and correct the installation position of the outer shell 4, ensure that the outer shell 4 is always coaxial with the wind hood 3 and the front cover 2 during installation, and avoid installation errors.

[0025] See also Figure 1 and Figure 6 As shown, a plurality of stator windings 31 arranged in an annular shape are provided on the upper part of the interior of the outer shell 4, and a ventilation duct 30 for air circulation is penetrated on the inner side of the outer shell 4, an inner flow pipe 32 is provided at the bottom of the inner cavity of the outer shell 4, and the inner flow pipe 32 is arranged on the outer side of the stator winding 31, an outer flow pipe 33 is provided on the upper part of the interior of the outer shell 4, a return pipe 1 34 connected to the stator winding 31 is provided at one end of the outer flow pipe 33, and a return pipe 2 35 connected to the stator winding 31 is provided at the other end of the outer flow pipe 33, and electromagnetic valve 2 36 is installed on the surface of the return pipe 1 34 and the return pipe 2 35.

[0026] The inner flow tube 32 is arranged in the inner cavity of the outer shell 4, and the outer flow tube 33 is arranged above and located outside the inner cavity of the outer shell 4. When the water in the inner flow tube 32 below is heated, its density will decrease. Because the thermal expansion effect increases the distance between water molecules, the hot water with reduced density will be affected by the buoyancy of the colder and denser water in the outer flow tube 33 above, thereby rising from the return pipe 2 35 to the outer flow tube 33. At the same time, the colder water in the outer flow tube 33 above sinks to the inner flow tube 32 below through the return pipe 1 34 due to its high density, forming a circulation flow of cold and hot water, thereby completing heat exchange and improving the heat dissipation efficiency of the outer shell 4.

[0027] When the present invention is in use, firstly, the four edges of the base of the outer shell 4 are limited by the corresponding side blocks 20 respectively, that is, the edge of the base of the outer shell 4 enters through the notch 26 and reaches the top of the abutment block 27. Under the push of the inclined surface of the top of the abutment block 27, the abutment block 27 moves toward the inner wall surface of the side block 20, and causes elastic compression to the compression spring 29, so that the telescopic rod 28 is shortened. The edge of the base is limited by the abutment block 27, and then the two-way screw 2 18 is driven to rotate by the handle 1 7, so that the two push plates 19 are close to each other, and the push plates 19 slide in the slide rail 21. The side of the push plate 19 is limited to the end face of the base, so as to align and correct the installation position of the outer shell 4, ensure that the outer shell 4 is always coaxial with the wind hood 3 and the front cover 2 when installed, and avoid installation errors. Since the outer shell 4 has been fixed, the wind hood 3 and the front cover 2 are placed in the bracket 2 10 and the bracket 1 13 respectively. At this time, the wind hood 3, the front cover 2 and the outer shell 4 are coaxial, and the bracket 2 10 and the bracket 1 13 are close to each other. At this time, the wind hood 3 and the front cover 2 are close to the end face of the outer shell 4, and then the wind hood 3 and the front cover 2 are rotated under the action of the roller rod 16 by toggling the wind hood 3 and the front cover 2, so as to facilitate the alignment of the wind hood 3 and the outer shell 4 and the installation holes on the front cover 2 and the outer shell 4, and the suction cup 15 in the bracket 2 10 and the bracket 1 13 is aligned with the wind hood 3 to The suction of the negative pressure unit causes the suction cup 15 to generate negative pressure suction, compressing the air inside the suction cup 15 to reduce its pressure, thereby adsorbing the wind hood 3 and the front end cover 2. After that, the second bracket 10 and the first bracket 13 continue to move closer, so that one end of the outer shell 4 is clamped with the wind hood 3, and the other end of the outer shell 4 is clamped with the front end cover 2. Then, the connection parts of the wind hood 3, the front end cover 2 and the outer shell 4 are tightened. During the installation process, there is no need to manually take and align the installation holes, which reduces the labor intensity and improves the installation efficiency. By arranging the inner flow tube 32 at the lower part of the inner cavity of the outer shell 4 and the outer flow tube 33 at the upper part and being located outside the inner cavity of the outer shell 4, when the water in the lower inner flow tube 32 is heated, its density will decrease. Because the thermal expansion effect increases the distance between water molecules, the hot water with reduced density will be affected by the buoyancy of the colder and denser water in the upper outer flow tube 33, thereby rising from the return tube 2 35 to the outer flow tube 33. At the same time, the colder water in the upper outer flow tube 33 sinks to the lower inner flow tube 32 through the return tube 1 34 due to its higher density, forming a circulation flow of cold and hot water, thereby completing heat exchange and improving the heat dissipation efficiency of the outer shell 4.
