Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fans, and more particularly relates to a fan motor with high-efficiency heat dissipation. Background Art

[0002] Cooling fans are typically used to dissipate heat in a small, targeted area. However, when the fan motor runs at high speed, it also generates heat. Therefore, when the fan runs at high speed for a long time, the heat generated can only be dissipated by the airflow generated by the fan's rotation, which is less effective. This affects the motor's service life and increases operating energy consumption. Utility Model Content

[0003] In view of the deficiencies of the prior art, the present invention provides a fan motor with high-efficiency heat dissipation, in which a circulation channel of coolant is provided inside to continuously dissipate heat from the stator of the motor.

[0004] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a fan motor with high-efficiency heat dissipation, comprising a support base, a rotating shell provided on the support base, a rotor provided on the inner wall of the rotating shell, the support base comprising a stator tube and a support plate, a stator provided on the outer wall of the rotor tube, a rotating shaft provided on the rotating shell, the rotating shaft extending into the rotating hole of the rotor tube, a bearing provided between the rotating shaft and the rotating hole, a heat absorption channel provided in the rotor tube, a heat dissipation channel provided in the support plate, one end of the heat absorption channel being connected to the rotating hole, the other end of the heat absorption channel being connected to one end connected to the heat dissipation channel, the other end of the heat dissipation channel being connected to the rotating hole, a circulating fan being provided on the rotating shaft, the heat absorption channel, the heat dissipation channel and the rotating hole being all filled with coolant, and an oil seal being provided at the opening of the rotating hole.

[0005] Furthermore, the heat absorption channel is in a three-dimensional spiral shape, and one end of the heat absorption channel is connected to the rotating hole and is close to the opening of the rotating hole.

[0006] Furthermore, the heat dissipation channel is in a planar spiral shape, and the inner end of the planar spiral heat dissipation channel is connected to the rotating hole, and the outer end of the heat dissipation channel is connected to the heat absorption channel near the bottom of the rotating hole.

[0007] Furthermore, a heat dissipation layer is provided at the bottom of the support plate, and the heat dissipation channel is located in the heat dissipation layer.

[0008] Furthermore, a through hole communicating with the rotation hole is provided at the bottom of the heat dissipation layer, and a plug is provided on the through hole.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the rotating shaft drives the circulating fan to rotate synchronously, so that the coolant circulates between the rotating hole, the heat absorption channel and the heat dissipation channel. The coolant absorbs the heat generated by the stator during operation in the heat absorption channel. When the coolant enters the heat dissipation channel, the heat is transferred to the outside world and finally returns to the rotating hole to complete the heat dissipation cycle. As long as the fan continues to rotate, the coolant can be driven to circulate through the circulating fan, thereby effectively dissipating heat to the stator and avoiding heat accumulation on the stator that affects its service life.

[0015] Reference Figure 1 and Figure 2 The utility model is further described.

[0016] A fan motor with high-efficiency heat dissipation includes a support base, a rotating shell 1 is provided on the support base, a rotor 2 is provided on the inner wall of the rotating shell 1, the support base includes a stator tube 3 and a support plate 4, a stator 5 is provided on the outer wall of the rotor 2 tube, a rotating shaft 6 is provided on the rotating shell 1, the rotating shaft 6 extends into the rotating hole 7 of the rotor 2 tube, a bearing 8 is provided between the rotating shaft 6 and the rotating hole 7, a heat absorption flow channel 9 is provided in the rotor 2 tube, a heat dissipation flow channel 10 is provided in the support plate 4, one end of the heat absorption flow channel 9 is connected to the rotating hole 7, the other end of the heat absorption flow channel 9 is connected to one end connected to the heat dissipation flow channel 10, and the other end of the heat dissipation flow channel 10 is connected to the rotating hole 7, a circulating fan 11 is provided on the rotating shaft 6, the heat absorption flow channel 9, the heat dissipation flow channel 10 and the rotating hole 7 are all filled with coolant, and an oil seal 12 is provided at the opening of the rotating hole 7.

[0017] Specifically, the coolant is cooling oil, which can absorb heat and lubricate the bearing 8 in the rotating hole 7 at the same time.

[0018] Specifically, since the fan is in the suction mode on the support plate 4 side when it is running, hot air can be sucked in from the support plate 4 side and blown out from the other side.

[0019] like Figure 1 As shown, in this embodiment, preferably, the heat absorption channel 9 is in a three-dimensional spiral shape, and one end of the heat absorption channel 9 is connected to the rotating hole 7 and is close to the opening of the rotating hole 7.

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, preferably, the heat dissipation channel 10 is in a planar spiral shape, and the inner end of the planar spiral heat dissipation channel 10 is connected to the rotating hole 7, and close to the bottom of the rotating hole 7, the outer end of the heat dissipation channel 10 is connected to the heat absorption channel 9.

[0021] like Figure 1 and Figure 2 As shown, fan blades are provided on the outer wall of the rotating shell 1. After the fan motor is started, the rotating shell 1 rotates, the rotating shaft 6 rotates, and the circulating fan 11 on the rotating shaft 6 rotates synchronously, so that the coolant in the rotating hole 7 flows upward into the heat absorption channel 9. The heat generated by the stator 5 during operation is absorbed by the coolant flowing in the heat absorption channel 9, and then enters the heat dissipation channel 10, and transfers the heat to the outside when passing through the heat dissipation channel 10, and finally returns to the bottom of the rotating hole 7 to complete the heat dissipation cycle. As long as the fan continues to rotate, the coolant can be driven to circulate through the circulating fan 11, thereby effectively dissipating the heat of the stator 5 and avoiding heat accumulation on the stator 5 affecting the service life.

[0022] Specifically, the three-dimensional spiral heat-absorbing flow channel 9 can absorb heat more effectively, while the planar spiral heat-dissipating flow channel 10 can release heat more effectively.

[0023] like Figure 1 As shown, in this embodiment, preferably, a heat dissipation layer 13 is provided at the bottom of the support plate 4, and the heat dissipation channel 10 is located in the heat dissipation layer 13 to improve the heat dissipation effect of the coolant.

[0024] Specifically, the heat dissipation layer 13 can be made of a metal material or a non-metal material with good thermal conductivity.

[0025] Specifically, the heat dissipation layer 13 and the support seat are integrated or fixedly connected. When integrated, they are made of the same material. When fixedly connected, they can be connected by strong glue or directly connected by bolts, but attention should be paid to sealing the connection gaps.

[0026] like Figure 1 As shown, in this embodiment, preferably, a through hole 14 connected to the rotating hole 7 is provided at the bottom of the heat dissipation layer 13, and a plug 15 is provided on the through hole 14. By removing the plug 15, the flow channel can be connected to the outside world, thereby facilitating the outflow and replacement of the internal coolant.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
