[0031] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.
[0032] As Figures 1-5As shown in the figure, an axial flow fan with a motor cooling device includes a housing 101, a motor 103, a connecting block 113 and a plurality of fan blades 102. The motor 103 is connected inside the housing 101. The connecting block 113 is arranged on the output shaft of the motor 103, and the fan blades 102 are connected to the connecting block 113. A first water storage tank 105, a second water storage tank 104 and an annular guide rail 106 are arranged inside the housing 101. Both the first water storage tank 105 and the second water storage tank 104 are fan-shaped structures, and the first water storage tank 105 and the second water storage tank 104 can move along the annular guide rail 106. A first connecting ring 108 is sleeved on the motor 103, and a cavity communicating with the first water storage tank 105 and the second water storage tank 104 is arranged on the first connecting ring 108.
[0033] An activity ring 107 is arranged on the annular guide rail 106. Both the first water storage tank 105 and the second water storage tank 104 are connected to the activity ring 107, and the first water storage tank 105 and the second water storage tank 104 are arranged oppositely.
[0034] A second connecting ring 109 is sleeved on the first connecting ring 108, and a transfer cavity is arranged on the second connecting ring 109. Both the first water storage tank 105 and the second water storage tank 104 communicate with the transfer cavity; a first opening and a second opening are arranged on the side wall of the transfer cavity, and a third opening and a fourth opening are arranged on the side wall of the cavity. The first opening and the second opening are arranged oppositely, and the third opening and the fourth opening are arranged oppositely.
[0035] A plurality of notches are arranged on the first connecting ring 108, changing the partial shape of the first connecting ring 108 and simultaneously changing the volume of different sections of the cavity to change the flow velocity of the water flow in the cavity, so that the water flow can contact the inner wall of the cavity more fully to absorb the heat of the motor 103; at the same time, due to the arrangement of the notches, more of the outer shell of the motor 103 is exposed, increasing the heat dissipation area of the motor 103, enabling the air flow and the water flow to cooperate to cool the motor 103 and improving the cooling effect of the motor 103.
[0036] A transmission wheel 115 is arranged on the first connecting ring 108. The transmission wheel 115 is in transmission cooperation with the output shaft of the motor 103. An installation frame is also arranged on the first connecting ring 108, and a rotating ring 116 is arranged on the installation frame. The rotating ring 116 is sleeved on the transmission wheel 115 and is in transmission cooperation with the transmission wheel 115. By means of the arrangement of the transmission wheel 115 and the rotating ring 116, a speed reduction effect is achieved on the rotating ring 116, so that the rotating speed of the rotating ring 116 is less than the rotating speed of the output shaft of the motor 103.
[0037] A movable plate 110 is arranged inside the first water storage tank 105. The movable plate 110 is located at the bottom of the first water storage tank 105 and at the bottom of the water flow.
[0038] A partition 112 is provided inside the first water storage tank 105. A first movable groove is provided on the partition 112, a second movable groove is provided on the side wall of the first movable groove, an extension rod 111 is provided on the movable plate 110, the extension rod 111 passes through the first movable groove, a convex rod 114 is provided on the extension rod 111, and the convex rod 114 extends out from the second movable groove; a push rod 117 is provided on the swivel ring 116.
[0039] A first magnet is provided at the bottom of the annular guide rail 106, a second magnet is provided on the movable plate 110, and the first magnet and the second magnet attract each other magnetically.
[0040] The structure of the second water storage tank 104 is the same as that of the first water storage tank 105.
[0041] When the fan works, one of the first water storage tank 105 or the second water storage tank 104 will be above the motor 103, and the other second water storage tank 104 or the first water storage tank 105 will be below the motor 103. Taking the first water storage tank 105 being above the motor 103 and the second water storage tank 104 being below the motor 103 as an example, the first water storage tank 105 is filled with cooling water, the second water storage tank 104 is not filled with cooling water, the first opening and the third opening are aligned, the second opening and the fourth opening are aligned, and the cooling water in the first water storage tank 105 enters the cavity through the transfer cavity. By using the fan-shaped structure of the first water storage tank 105 and the partition 112, the area of the water outlet of the first water storage tank 105 is reduced, the water output of the first water storage tank 105 is controlled, the convex rod 114 and the push rod 117 are in a staggered state, and the water flow in the first water storage tank 105 slowly flows into the second water storage tank 104 through the cavity to cool the motor 103; since the water flow gradually flows into the second water storage tank 104, the airflow guided by the fan blade 102 passes through both the first water storage tank 105 and the second water storage tank 104, and the water flow that has absorbed the heat of the motor 103 can be quickly cooled after entering the second water storage tank 104, ensuring that the cooling water can be reused; when the water flow in the first water storage tank 105 flows into the second water storage tank 104, the movable plate 110 descends with the liquid level, and the movable plate 110 drives the extension rod 111 to move together; when the cooling water in the first water storage tank 105 runs out, the convex rod 114 moves to one side of the push rod 117 as the movable plate 110 descends, and the push rod 117 rotates with the swivel ring 116 to push the convex rod 114 to move, and the first water storage tank 105 and the second water storage tank 104 rotate and exchange positions. When the first water storage tank 105 rotates to below the motor 103, the first electromagnet and the second electromagnet attract each other, causing the movable plate 110 to move towards the bottom of the first water storage tank 105. The movement of the movable plate 110 drives the convex rod 114 to move, and the convex rod 114 is staggered from the push rod 117. At this time, the first water storage tank 105 is below the motor 103, the second water storage tank 104 is above the motor 103, and the cooling water in the second water storage tank 104 flows into the first water storage tank 105 through the cavity to continue cooling the motor 103.
[0042] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the embodiments of the present disclosure.
