Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an auxiliary heat dissipation structure for an RO pump motor. Background Technology

[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors and generators, such as RO pump motors. In existing RO pump motors, the carbon brushes are integrally molded with the plastic end cap, and the carbon brushes are installed in the plastic end cap. Plastic has poor thermal conductivity, and the RO pump motor uses the end cap to conduct heat with the outside air to assist in heat dissipation. That is, the air contacts the plastic end cap and carries away the heat. However, the plastic end cap needs to have openings to position the motor body. The position of these openings reduces the heat dissipation area of ​​the plastic end cap, thus affecting its heat dissipation effect. Therefore, it is necessary to design a new heat dissipation structure for RO pump motors to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an auxiliary heat dissipation structure for an RO pump motor. The end cover and the carbon brush of the motor body are connected by a mounting base plate. The mounting base plate improves the thermal conductivity, and the connection between the heat-conducting plate and the positioning hole of the end cover increases the heat dissipation area of ​​the end cover, thereby improving its heat dissipation effect.

[0004] An auxiliary heat dissipation structure for an RO pump motor includes an end cap mounted on a carbon brush of the pump body. A mounting base is provided on one side of the end cap, and the end cap is connected to the carbon brush of the pump body through the mounting base. A positioning hole is provided in the center of the end cap, and a heat-conducting plate is provided on the other side of the end cap at the position of the positioning hole.

[0005] Preferably, a plurality of mounting posts are provided on one side of the end cap, a plurality of mounting holes are provided on the mounting base plate, and the carbon brush of the body is connected to the mounting holes of the mounting base plate and the mounting posts of the end cap by screws.

[0006] Preferably, the mounting base plate has an opening in the middle, through which the machine body passes and connects to the positioning hole.

[0007] Preferably, the end cap is provided with a wire hole, and a connecting wire is inserted into the wire hole.

[0008] Preferably, the end cap has a receiving protrusion in the middle of one side where the heat-conducting plate is provided, and the end cap has heat dissipation ribs evenly arranged around the receiving protrusion. The positioning hole has a through hole, and the heat-conducting plate has a claw that engages with the through hole.

[0009] The beneficial effects of this utility model are: the auxiliary heat dissipation structure of the RO pump motor cooperates with the end cover and the mounting plate, so that the end cover and the carbon brush of the machine body are connected through the mounting plate. The mounting plate improves the thermal conductivity, and the connection between the heat conduction plate and the positioning hole of the end cover increases the heat dissipation area of ​​the end cover, thereby improving its heat dissipation effect.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0014] like Figures 1 to 2 As shown, an auxiliary heat dissipation structure for an RO pump motor includes an end cover 2 mounted on a carbon brush 1 of the motor body. A mounting base plate 3 is provided on one side of the end cover 2, and the end cover 2 is connected to the carbon brush 1 of the motor body through the mounting base plate 3. A positioning hole 4 is provided in the center of the end cover 2, and a heat-conducting plate 5 is provided on the other side of the end cover 2 at the position of the positioning hole 4.

[0015] The working principle of the RO pump motor auxiliary heat dissipation structure described in this utility model is achieved through the cooperation of the end cover 2 and the mounting base plate 3. Figures 1 to 2 As shown, the end cap 2 and the carbon brush 1 of the motor body are connected by the mounting base 3. The mounting base 3 can be made of PCB board or thermally conductive and flame-retardant material, which has good thermal conductivity and can conduct heat outward to the carbon brush 1 of the motor body. The heat conduction plate 5 is connected to the positioning hole 4 of the end cap 2, which can block the positioning hole 4, increase the heat dissipation area of ​​the end cap 2 in contact with the air and prevent water from splashing into the motor body, thereby improving its heat dissipation effect. Compared with the traditional motor, the auxiliary heat dissipation structure of the RO pump motor can enhance the thermal conductivity and heat dissipation effect of the end cap 2 through the cooperation of the end cap 2 and the mounting base 3.

[0016] Specifically, one side of the end cap 2 is provided with multiple mounting posts 6, the mounting base plate 3 is provided with multiple mounting holes, and the carbon brush 1 of the machine body is connected to the mounting holes of the mounting base plate 3 and the mounting posts 6 of the end cap 2 by screws. The mounting base plate 3 has an opening 7 in the middle, through which the machine body passes to connect with the positioning hole 4. The end cap 2 is provided with a wire hole, and a connecting wire 8 is inserted into the wire hole, such as... Figures 1 to 2 As shown, the carbon brush 1 of the body is connected to the end cover 2 via the mounting base 3 instead of being integrally formed. The mounting base 3 can be made of PCB board or thermally conductive and flame-retardant material, which has good thermal conductivity and can conduct heat outward to the carbon brush 1 of the body. It is also convenient to disassemble the end cover 2 and the mounting base 3. The opening 7 of the mounting base 3 facilitates the connection and limitation of the positioning hole 4 between the body and the end cover 2. The wire hole of the end cover 2 facilitates the connection of the connecting wire 8, such as the power supply wiring.

[0017] Furthermore, the end cap 2 has a receiving protrusion 9 in the middle of one side where the heat-conducting plate 5 is located, and the end cap 2 has heat dissipation ribs 10 evenly arranged around the receiving protrusion 9. A through hole 11 is provided in the positioning hole 4, and a claw 12 that engages with the through hole is provided on the heat-conducting plate 5. Figures 1 to 2 As shown, the heat dissipation ribs 10 of the end cap 2 increase the heat dissipation contact area and improve its heat dissipation effect. The heat conduction plate 5 can be made of heat-conducting plastic plate or metal plate. The claws 12 of the heat conduction plate 5 are engaged with the through holes 11 of the positioning hole 4. The claws 12 can be made of elastic material, so that the staff can press the heat conduction plate 5 to make the claws 12 engage in the through holes 11 for fixation.
