Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor with a liquid cooling structure. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses a rotating magnetic field generated by a current-carrying coil (i.e., the stator winding) to act on the rotor, forming a magnetoelectric torque. The electric motor is mainly composed of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field is related to the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] Traditional motors have some drawbacks. During operation, motors generate a lot of heat. Motors usually dissipate heat by adding heat sinks to the surface of the casing. However, heat sinks alone cannot dissipate heat quickly enough. Overheating of the motor's internal components may damage them. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a motor with a liquid cooling structure includes a motor body 1, a protective rear shell 2, and a drive shaft 3. A cooling auxiliary mechanism 6 is provided at the rear end of the motor body 1. The cooling auxiliary mechanism 6 includes a fixing rod 61 fixedly installed at the rear end of the motor body 1. A circulation pipe 62 is sleeved on the outside of the fixing rod 61. The circulation pipe 62 penetrates the interior of the protective rear shell 2 and is fixedly connected to the protective rear shell 2. A connecting pipe 63 is fixedly connected to the front end of the circulation pipe 62. A pump body 64 is installed at the upper end of the connecting pipe 63. A connecting pipe 65 is installed at the upper end of the pump body 64. A drain pipe 66 is installed on the front end of the circulation pipe 62 near the connecting pipe 63. A liquid storage tank 67 is fixedly connected to the rear end of the drain pipe 66. An installation ring 68 is fixedly connected to the outside of the fixing rod 61 near the circulation pipe 62. A retaining plate 69 is fixedly connected to the outside of the installation ring 68.

[0021] In this embodiment, the upper end of the liquid storage tank 67 is equipped with an injection port 610. The overall shape of the circulation pipe 62 is spiral. The circulation pipe 62 is located inside the protective rear shell 2. The connecting pipe 63 is connected to the circulation pipe 62. The connecting pipe 65 is connected to the liquid storage tank 67. The liquid storage tank 67 is sleeved on the outer side of the protective rear shell 2. The liquid storage tank 67 is fixedly connected to the protective rear shell 2. The circulation pipe 62 is connected to the unblocking pipe 66. The unblocking pipe 66 is connected to the liquid storage tank 67. The connecting pipe 63, the connecting pipe 65, and the unblocking pipe 66 are all L-shaped. The baffle plate 69 is conical. The injection port 610 is connected to the liquid storage tank 67.

[0022] Specifically, the injection port 610 is opened, and coolant is injected into the storage tank 67 through the injection port 610. Then, the injection port 610 is closed. The rear end of the motor body 1 generates heat, and the pump body 64 is started. The pump body 64 draws coolant from the storage tank 67 through the connecting pipe 65 and discharges the coolant into the circulation pipe 62. The coolant in the circulation pipe 62 flows back into the storage tank 67 through the drain pipe 66. The coolant is cooled by passing through the circulation pipe 62, so that when the outside air enters the protective rear shell 2, it comes into contact with the baffle plate 69, and the air flows along the baffle plate. The coolant flows from the plate 69 into the circulation pipe 62, allowing the air to come into contact with the cool air emitted from the circulation pipe 62. This cools the air and the motor body 1, thereby improving the cooling efficiency of the motor body 1. The coolant in the storage tank 67 is discharged into the circulation pipe 62 through the pump body 64, and external air enters into the protective rear shell 2, thus coming into contact with the circulation pipe 62. The coolant in the circulation pipe 62 then cools the air, achieving the purpose of facilitating the cooling of the motor body 1 and greatly improving the cooling efficiency of the motor body 1.

[0023] In this embodiment, the protective rear shell 2 is installed on the outer side of the rear end of the motor body 1 near the fixing rod 61, the transmission shaft 3 is installed inside the motor body 1, the control box 4 is installed on the upper end of the motor body 1, and the support base 5 is fixedly connected to the lower end of the motor body 1.

[0024] Specifically, the worker first places the motor body 1 in the designated position, so that the support base 5 contacts the external machinery. Then, the support base 5 is fixed to the external machinery with bolts, so that the motor body 1 can be installed on the external machinery. The motor body 1 is then started, so that the motor body 1 drives the transmission shaft 3 to rotate.

[0025] Working principle:

[0026] In use, the worker first places the motor body 1 in the designated position, so that the support base 5 contacts the external machinery. Then, the support base 5 is bolted to the external machinery, thus installing the motor body 1. At this point, the injection port 610 is opened, and coolant is injected into the storage tank 67 through the injection port 610. The injection port 610 is then closed, and the motor body 1 is started, causing the drive shaft 3 to rotate. This generates heat at the rear end of the motor body 1. The pump body 64 is then started, drawing coolant from the storage tank 67 through the connecting pipe 65 and discharging it into the circulation pipe 62. The coolant in the circulation pipe 62 then flows back into the storage tank 67 through the unblocking pipe 66. Coolant is cooled outward through circulation pipe 62, allowing outside air to enter the protective rear shell 2 and come into contact with baffle plate 69. This causes the air to flow along baffle plate 69 into circulation pipe 62, where it comes into contact with the cold air emitted by circulation pipe 62. This cold air cools the air and allows the air to cool the motor body 1, thereby improving the cooling efficiency of the motor body 1. Coolant in storage tank 67 is discharged into circulation pipe 62 through pump body 64, and outside air enters the protective rear shell 2, coming into contact with circulation pipe 62. The coolant in circulation pipe 62 then cools the air, achieving the purpose of facilitating the cooling of the motor body 1 by the air, thus greatly improving the cooling efficiency of the motor body 1.
