Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a motor with a stator cooling structure. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a stator structure with motor cooling capability", and its application number is "CN202020352456.5". This patent mainly uses the elasticity of the rubber plug to make the two sets of stator cores close to each other without affecting the stability, and can quickly dissipate heat, thereby realizing the cooling function of the stator core.

[0003] Simply using natural heat dissipation to dissipate heat for large stator motors has a very poor effect. Not only is the heat dissipation effect not strong, but it is also difficult to meet the heat dissipation needs of the stator motor under long-term high-load operation. Large stator motors are huge in size and generate more and more heat. If only natural convection and convection are used for heat dissipation, it is difficult for the heat to be conducted and convected from the inside of the motor to the environment in time, which can easily cause overheating of components such as the stator winding and insulator, thereby affecting the working reliability and service life of the motor. Utility Model Content

[0004] The utility model aims to provide a motor with a stator cooling structure. By providing a cooling mechanism, when coolant is introduced into the interior of a shell through a liquid inlet, the coolant fully contacts with the fins after passing through the connecting holes on the fins. After the coolant contacts with the interior of the shell and the fins, the coolant absorbs the heat generated by both, and is discharged through a liquid outlet, thereby realizing rapid heat dissipation and cooling of the stator, solving the problem that the heat dissipation effect of a large stator motor using only natural heat dissipation is very poor, not only the heat dissipation effect is not strong, but also it is difficult to meet the heat dissipation needs of the stator motor working at high load for a long time.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a motor with a stator cooling structure, comprising a stator and a housing, wherein a cooling mechanism, a mounting mechanism, a positioning mechanism, a filtering mechanism and a connecting mechanism are arranged on the stator;

[0007] The cooling mechanism comprises a shell fixedly mounted on the stator, a plurality of fins are fixedly mounted inside the shell, a plurality of connecting holes are provided on the plurality of fins, a liquid inlet is provided on the shell, and a liquid outlet is provided on the shell.

[0008] Furthermore, the mounting mechanism includes a second connector fixedly mounted on the liquid inlet, a first connector is provided on the second connector, a plurality of connecting blocks are fixedly mounted on the first connector and the second connector, and a bolt is threadedly connected between the first connector and the second connector.

[0009] Furthermore, the positioning mechanism includes a positioning assembly and a sealing assembly, the positioning assembly includes a plurality of positioning rods fixedly mounted on the right side surface of the second connector, a plurality of positioning grooves are provided on the left side surface of the first connector, and the plurality of positioning rods are slidably connected to the inner walls of the plurality of positioning grooves respectively.

[0010] Furthermore, the sealing assembly includes sliding grooves respectively opened on the right side surface of the second connector and the left side surface of the first connector, and the inner walls of the two sliding grooves are slidably connected with sealing gaskets.

[0011] Furthermore, the filtering mechanism comprises a connecting ring slidably connected to the inner wall of the sealing gasket, and a filter screen is fixedly mounted on the inner wall of the connecting ring.

[0012] Furthermore, two grooves are provided inside the first connecting head, the inner walls of the two grooves are slidably connected with pistons, the left surfaces of the two pistons are fixedly installed with sliding rods, the left ends of the two sliding rods extend to the left side of the first connecting head, the left ends of the two sliding rods are fixedly installed with pads, the two sliding rods are sleeved with springs, the right ends of the two springs are fixedly connected to the left surface of the piston, and the left ends of the two springs are fixedly connected to the inner wall of the groove.

[0013] The utility model has the following beneficial effects:

[0014] 1. By providing a cooling mechanism, when the coolant is introduced into the interior of the shell through the liquid inlet, the coolant fully contacts the fins after passing through the connecting holes on the fins. After the coolant contacts the interior of the shell and the fins, it absorbs the heat generated by both, and is discharged through the liquid outlet, thereby realizing rapid heat dissipation and cooling of the stator.

[0015] 2. By providing a filtering mechanism, the filter can filter the coolant before entering the shell to avoid excessive impurities in the coolant affecting the heat conduction effect or causing blockage, thereby ensuring the normal operation of the cooling cycle. The spring and the piston cooperate with each other. After the first connecting head and the second connecting head are installed by bolts, the gasket contacts the connecting ring, and the spring is stretched, so that the gasket applies pressure to the connecting ring, so that the two gaskets can fix the position of the connecting ring to prevent it from loosening, which not only improves the tightness of the connection between the connecting ring and the sealing gasket, but also facilitates the disassembly and replacement of the filter.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
