Description

Technical Field

[0001] The utility model relates to the technical field of micro motors, in particular to a heat dissipation cover for a micro motor. Background Art

[0002] The full name of micromotor is "micro electric motor", which refers to a motor with a diameter less than 160mm or a rated power less than 750mW. Micromotor is often used in control systems or transmission mechanical loads to realize the detection, analytical operation, amplification, execution or conversion of electromechanical signals or energy. In the existing technology, common micromotors have a single function and do not have a cooling function. When the micromotor runs for a long time, its internal temperature is too high and it will burn out directly if it is not stopped in time, thus affecting its use. In order to improve the heat dissipation efficiency of the micromotor, a heat dissipation cover is needed, but the existing heat dissipation cover still has the following shortcomings:

[0003] For example, the utility model with application number 202220274486.8 discloses a micromotor with a heat dissipation function. The utility model cooperates with the upper shell, the lower shell and the heat dissipation mechanism so that when the water pipe is distributed between heat sink one and heat sink two, the flow of internal water resources can effectively alleviate the heat absorbed by the surface of the heat sink, which is beneficial to the heat dissipation function of the motor body. When the fan blades rotate due to the operation of the motor body, the air can flow in the air duct to further improve the heat dissipation effect of the motor body. However, similar to the comparative documents of the above-mentioned application, when the existing heat dissipation cover is used, most of the heat dissipation covers are installed with the micromotor by bolts, which makes the installation and disassembly of the heat dissipation cover time-consuming and labor-intensive, resulting in the problem of reduced practicality and reduced use efficiency of the heat dissipation cover.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a micro motor heat dissipation cover is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a micro motor heat dissipation cover to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a micromotor heat dissipation cover, comprising a main shell and a mounting assembly, a rotating shaft is arranged at the middle end of the main shell, a mounting assembly is arranged at the rear end of the main shell, and the mounting assembly comprises a wind cover, a threaded mounting ring, a mounting cover, a clamping groove, a clamping block and a heat dissipation dustproof net, a threaded mounting ring is additionally arranged on the outside of the wind cover, and the outside of the threaded mounting ring is connected to the mounting cover, and a clamping groove is opened on the outside of the mounting cover, and a clamping block is connected to the inside of the clamping groove, a heat dissipation dustproof net is installed on the outside of the clamping block, and a heat dissipation assembly is arranged inside the main shell.

[0007] Furthermore, a rotor is arranged outside the rotating shaft, and a stator is distributed outside the rotor.

[0008] Furthermore, the outer side of the wind shield is flush with the outer side of the mounting shield, and the mounting shield is rotatably connected to the wind shield via a threaded mounting ring.

[0009] Furthermore, the inner dimensions of the clamping groove match the outer dimensions of the clamping block, and the heat dissipation and dustproof net is connected to the mounting cover through the clamping block.

[0010] Furthermore, the heat dissipation component includes a heat dissipation cavity, a graphite layer and a water pipe. A graphite layer is added to the inner side of the heat dissipation cavity, and the heat dissipation cavity is connected to the water pipe.

[0011] Furthermore, the heat dissipation component also includes a water outlet, a water inlet and a heat dissipation fan, and the water outlet is arranged at the rear end of the water pipe, and the water inlet is arranged at the front end of the water pipe, and the heat dissipation fan is installed at the rear end of the rotating shaft.

[0012] Furthermore, the inner dimensions of the heat dissipation cavity match the outer dimensions of the graphite layer, and the inner side of the heat dissipation cavity fits tightly with the outer side of the graphite layer.

[0013] Furthermore, the water pipe is embedded in the heat dissipation cavity, and the water pipe is spirally distributed inside the heat dissipation cavity.

[0014] The utility model provides a micro motor heat dissipation cover, which has the following beneficial effects:

[0015] The utility model discloses a kind of heat dissipation fan, and the heat dissipation fan of the micromotor is installed with the heat dissipation cover of the micromotor by the installation assembly provided at the rear end of the main shell body when the heat dissipation cover of the micromotor is used.

[0016] 2. The utility model can avoid the situation that most heat dissipation covers have only a single heat dissipation method when the micromotor heat dissipation cover is used through the heat dissipation component arranged inside the main shell, which makes the micromotor easy to be damaged due to small space or high power, resulting in reduced efficiency of the heat dissipation cover. A heat dissipation cavity is opened in the space on the inner wall of the main shell, and a graphite layer is tightly added inside the heat dissipation cavity. The heat dissipated by the motor components inside the main shell is efficiently guided out through the arrangement of the graphite layer, that is, the heat is guided to the inside of the heat dissipation cavity through the graphite layer, and the coolant is transported to the water pipe arranged inside the heat dissipation cavity through the water inlet installed at one end of the outside of the main shell, the coolant is circulated in the heat dissipation cavity through the spirally wound water pipe, and discharged from the water outlet, and the heat inside the heat dissipation cavity is taken out by the water pipe in combination with the coolant, so that the motor components inside the main shell are quickly cooled, and the cooling fan installed at the rear end of the rotating shaft is used for secondary cooling, so as to further improve the heat dissipation efficiency of the micromotor during use and extend the service life of the micromotor.
