Abstract
Description
Technical Field
[0001] This utility model relates to the field of dual-head DC motor technology, and in particular to a dual-head DC motor with heat dissipation function. Background Technology
[0002] Dual-head DC fan motors use motors to drive fan blades, accelerating airflow to achieve cooling and air circulation. However, existing dual-head DC fan motor designs lack adequate heat dissipation mechanisms, causing the motor to operate in high-temperature environments, making it prone to damage and shortening its lifespan. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a dual-head DC motor with heat dissipation function.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] The present invention discloses a dual-head DC motor with heat dissipation function, comprising a housing, a first fan blade, a second fan blade, and a dual-head motor fixed inside the housing; the upper and lower surfaces of the housing are respectively provided with an air outlet and a bottom through hole; one output end of the dual-head motor extends from the air outlet and is fixedly connected to the first fan blade; the other output end of the dual-head motor extends from the bottom through hole and is fixedly connected to the second fan blade; an air inlet is provided on the side surface of the housing at a position directly opposite the dual-head motor; the dual-head motor is sealed in the bottom through hole.
[0006] Furthermore, the housing consists of an upper cover plate, a flow guide ring, and a bottom cover;
[0007] The bottom cover is circular; the top cover is fixed to the bottom cover; the air outlet is located on the top cover; the bottom through hole is located on the bottom cover; the guide ring is coaxially located inside the bottom cover; the guide ring consists of a bottom ring fixed to the top cover, a top ring fixed inside the bottom cover, and multiple guide plates fixed between the bottom ring and the top ring; the guide plates are evenly arranged along the circumference of the bottom ring; an air inlet channel is formed between adjacent guide plates; one end of each air inlet channel faces the dual-head motor.
[0008] Furthermore, the inner hole of the bottom ring is provided with a positioning sleeve; the inner hole of the positioning sleeve matches the outer shell of the dual-head motor; the dual-head motor is embedded in the positioning sleeve.
[0009] Furthermore, the positioning sleeve is made of metal.

[0012] Furthermore, a motor bracket is fixed to the side of the housing away from the air outlet; the dual-head motor is fixed to the motor bracket.
[0013] With the above structure, the beneficial effects of this utility model are as follows: when the dual-head motor starts, the first and second fan blades move synchronously; the second fan blade generates airflow and pushes it outward; since the air outlet is not sealed, the rotating first fan blade creates negative pressure between the air outlet and the inner cavity of the housing; this allows external air to enter from the air inlet and contact the housing of the dual-head motor, and then be discharged outward from the air outlet by the thrust of the first fan blade; during operation, the air entering from the air inlet contacts the surface of the dual-head motor to dissipate heat, cooling the dual-head motor, stabilizing the operating temperature of the dual-head motor, and improving the service life of the motor.

[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] like Figures 1 to 5As shown, the present invention discloses a dual-head DC motor with heat dissipation function, comprising a housing 1, a first fan blade 2, a second fan blade 3, and a dual-head motor 5 fixed inside the housing 1; the upper and lower surfaces of the housing 1 are respectively provided with an air outlet 10101 and a bottom through hole 10301; one output end of the dual-head motor 5 extends from the air outlet 10101 and is fixedly connected to the first fan blade 2; the other output end of the dual-head motor 5 extends from the bottom through hole 10301 and is fixedly connected to the second fan blade 3; an air inlet 104 is provided on the side surface of the housing 1 at a position directly opposite the dual-head motor 5; the dual-head motor 5 is sealed in the bottom through hole 10301;
[0026] After the entire dual-head DC motor is installed on the equipment, the dual-head motor 5 starts, causing the first blade 2 and the second blade 3 to move synchronously. The second blade 3 generates airflow that pushes it outward. Since the air outlet 10101 is not sealed, the rotating first blade 2 creates a negative pressure between the air outlet 10101 and the inner cavity of the housing 1. This causes external air to enter from the air inlet 104 and come into contact with the housing of the dual-head motor 5, and then be discharged outward from the air outlet 10101 by the thrust of the first blade 2. During operation, the air entering from the air inlet 104 contacts the surface of the dual-head motor 5 to dissipate heat, cooling the dual-head motor 5 and stabilizing the operating temperature of the dual-head motor 5, thus improving the service life of the motor.
[0027] In a preferred embodiment of the present invention, the housing 1 is composed of an upper cover plate 101, a flow guide ring 102, and a bottom cover 103;
[0028] The bottom cover 103 is circular; the upper cover plate 101 is fixed to the bottom cover 103; the air outlet 10101 is provided on the upper cover plate 101; the bottom through hole 10301 is provided on the bottom cover 103; the guide ring 102 is coaxially provided inside the bottom cover 103; the guide ring 102 is composed of a bottom ring 10202 fixed on the upper cover plate 101, a top ring 10203 fixed inside the bottom cover 103, and multiple guide plates 10204 fixed between the bottom ring 10202 and the top ring 10203; the guide plates 10204 are evenly arranged along the circumference of the bottom ring 10202; an air inlet channel is formed between adjacent guide plates 10204; one end of each air inlet channel faces the dual-head motor 5.
[0029] Since the guide ring 102 and the bottom cover 103 are coaxially arranged, the airflow entering from the air inlet 104 enters the interior of the housing 1 and forms an annular airflow between the guide ring 102 and the bottom cover 103. Then, the airflow between the guide ring 102 and the bottom cover 103 enters the interior of the guide ring 102 from the air inlet channels in various directions and contacts the surface of the dual-head motor 5. Finally, the airflow carries away the heat of the dual-head motor 5 and is discharged from the top cover 101. The multiple guide vanes 10204 form an air inlet channel with a diversion function, which makes the airflow of each air inlet channel tend to be consistent, so that the surfaces of the dual-head motor 5 can dissipate heat more evenly.
[0030] In a preferred embodiment of this utility model, the inner hole of the bottom ring 10202 is provided with a positioning sleeve 10201; the inner hole of the positioning sleeve 10201 matches the housing of the dual-head motor 5; the dual-head motor 5 is embedded in the positioning sleeve 10201; the bottom ring 10202 is attached to the bottom cover 103, and after being sealed in the positioning sleeve 10201 by the dual-head motor 5, the airflow inside the housing 1 can only be discharged from the air outlet 10101; the positioning of the dual-head motor 5 by the bottom ring 10202 makes the coaxiality of the dual-head motor 5, the guide ring 102, and the housing 1 higher.
[0031] In a preferred embodiment of this utility model, the positioning sleeve 10201 is made of metal material.
[0032] In a preferred embodiment of this utility model, the positioning sleeve 10201 is made of any one of iron, copper, or aluminum materials.
[0033] In a preferred embodiment of this utility model, the guide ring 102 is made of metal or plastic.
[0034] In a preferred embodiment of this utility model, a motor bracket 4 is fixed on the side of the housing 1 away from the air outlet 10101; the dual-head motor 5 is fixed on the motor bracket 4.
[0035] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
