In this case, a radiator fan is provided, which is rotatably connected with an impeller set 300 in the air intake cover 100, and it is worth noting that the biaxial motor 600 arranged in the air intake cavity 101 can drive the impeller set 300 to perform Rotate, the impeller set 300 is provided with a deflector block 400, an air intake channel 310 is formed between the outer wall of the impeller set 300 and the outer wall of the deflector block 400, and there is a communication gap between the impeller set 300 and the inner wall of the air intake chamber 101 for air intake. , the output end of the biaxial motor 600 is fixedly connected with the guide block 400; the guide block 400 has a conical structure, and its caliber gradually becomes larger along the air intake direction; the guide block 400 and the impeller group 300 are connected through multiple connections The block 420 remains fixedly connected. When the set biaxial motor 600 drives the set impeller set 300 to rotate, it is located at the inlet of the air intake chamber 101. Due to the high speed of the impeller set 300, a certain negative pressure will be formed at this position , so as to realize suction, and it is worth noting that there is an open space in the middle of the impeller set 300, and the flow guide block 400 is connected with the connecting block 420 in the open space, so when the impeller set 300 rotates, there are two The air intake mode of the position, one is the flow gap between the air intake cover 100 and the outer wall of the impeller set 300, and the other is the air intake channel 310 between the impeller set 300 and the middle of the flow guide block 400, through which In this way, the total amount of intake air of the radiator fan can be increased, thereby improving the blowing effect of the radiator fan.

In this case, a mounting part 500 is also fixedly installed in the air intake cover 100, and the middle part of the mounting part 500 is fixedly installed with a mounting ring 510 for placing the biaxial motor 600. The edge of the mounting part 500 is curved, and the mounting part 500 The outer wall is fixedly connected to the inner wall of the air intake chamber 101, and a clamping block 410 is also fixedly connected to the outer wall on the right side of the deflector block 400; Specifically, the middle part of the installation ring 510 provides an installation space for placing the biaxial motor 600. In order to ensure a good sound insulation and vibration reduction effect, the inner wall of the installed installation ring 510 is also provided with a sound insulation layer, which is wrapped in the biaxial On the outer wall of the motor 600, and in order to ensure a good sound insulation effect, the installed installation ring 510 is inserted into the installation groove 411 opened in the middle of the clamping block 410, and it is worth noting that, because the double-axis motor 600 is in the actual During use, the impeller set 300 will be driven to rotate, so the inner wall of the mounting groove 411 and the outer wall of the mounting ring 510 are kept in sliding fit.

As mentioned above, after the double-axis motor 600 is fixedly installed by the provided mounting part 500, after the impeller set 300 rotates to realize the blowing, and two airflows are generated from the flow gap and the air intake passage 310 respectively for blowing, for The mounting part 500 also effectively separates the above two air streams. Specifically, the edge of the mounting part 500 is provided with a plurality of first through grooves 501 in a circular structure, and the middle part of the mounting part 500 is provided with a circular structure. The second through slot 502, the air flow in the flow gap will continue to flow from the first through slot 501 provided on the mounting part 500 to the air outlet chamber 201, and the air flow blown from the air intake channel 310 will flow from the first through slot 501 provided on the mounting part 500 to the air outlet chamber 201. The second through groove 502 on the piece 500 continues to flow to the air outlet cavity 201, and in order to prevent the two airflows from colliding with each other in the actual circulation process to form turbulent flow, which will affect the blowing efficiency, in this case, the installation piece 500 An annular plate 520 is also installed on it, and the outer wall of the edge of the annular plate 520 is slidably matched with the outer wall of the impeller group 300; the clamping block 410 is located in the middle of the annular plate 520; the annular plate 520 connects the first through groove 501 and the second The two through-slots 502 are separated so that the air intake channel 310 remains in communication with the second through-slot 502, and the flow gap between the impeller set 300 and the air-intake chamber 101 is in communication with the first through-slot 501, through the set arc-shaped structure. The ring-shaped plate 520 can well separate the above two airflows, and avoid the turbulent flow caused by their contact with each other, so as to ensure efficient blowing.

In this case, effective blowing can be achieved through the set of impellers 300, and the generation of turbulent flow can be effectively avoided and efficient blowing can be ensured through the two gas circulation tracks provided. However, the rotation of a single impeller set 300 drives Gas flow, the flow rate of gas is limited, so the blowing effect will also be limited, so in this case, along the flow direction of gas, a rotating member 700 that rotates relative to the intake cover 100 is also provided for further Drive the gas to flow. Specifically, the rotating part 700 is fixedly connected to the other output end of the biaxial motor 600, and one end of the biaxial motor 600 is fixedly connected to the impeller group 300. In this case, when the biaxial motor 600 rotates, It can respectively drive the impeller set 300 and the rotating member 700 to move synchronously. When the rotating member 700 rotates, the first blade set 710 arranged on the left outer wall of the rotating member 700 will keep rotating. It is worth noting that, in At the edge of the impeller set 300, the gas will continue to be transported through the first fan blade set 710 in the rotating state, and it is worth noting that the annular strip 701 provided on the outer wall of the left edge of the rotating member 700 can ensure the flow The airflow through the first slot 501 can be stably captured by the first fan blade set 710 and continue to be transported along the direction of the upper blades of the first fan blade set 710. In this way, the airflow can be accelerated again, And then guarantee the high-efficiency blowing of the radiator fan.

At the same time, the second fan blade set 720 is installed on the right outer wall of the rotating member 700 to assist the rotation of the rotating member 700. The first fan blade set 710 in the state needs to break the original flow track of the airflow again, so the rotation of the rotating part 700 will drive the larger output pressure of the biaxial motor 600, so in this case, there is also a set on the rotating part 700 The second fan blade group 720, the second fan blade group 720 does not have an external driving force, but uses the airflow flowing through the second through slot 502 to assist its rotation, specifically, it also includes the right side of the rotating member 700 The guide piece 800 is used to guide the gas flowing through the through hole 702, and acts on the second blade set 720 to assist the rotation of the rotating piece 700; a curved plate 810 is fixedly installed on the outer wall of the left edge of the guide piece 800 for Guide the gas flowing through the through holes 702. Specifically, the middle part of the rotating member 700 is provided with a plurality of through holes 702 in an annular structure, and the through holes 702 are in communication with the second through groove 502. The airflow of the through groove 502 will flow out from the through hole 702, and blow on the set curved plate 810, continue to flow along the bending direction of the bent plate 810, and blow on the set second fan blade set 720, assisting the rotating part 700 rotates, and the edge of the guide 800 has a ring-shaped first air guide groove 801, and the air flow acting on the second fan blade set 720 can rotate from the set second fan blade set 720 after assisting the rotation of the second fan blade set 720. An air guide groove 801 continues to flow into the air outlet cavity 201 .

In this case, since the set biaxial motor 600 needs to simultaneously drive the set impeller set 300 and the rotating member 700 to rotate synchronously, a certain amount of heat will be generated during its operation. A certain design, specifically, a heat dissipation tube 730 is fixedly installed in the middle of the right side of the rotating member 700, and a heat dissipation channel 731 is opened inside it. The middle part is provided with an overlapping groove overlapping the outer wall of the cooling tube 730 , and the inner wall of the overlapping groove is provided with a plurality of second air guiding grooves 802 in a circular structure. The middle part of the mounting part 500 has a ring-shaped structure and is uniformly provided with a plurality of first heat dissipation holes 503; the left inner wall of the heat dissipation channel 731 is uniformly provided with a second heat dissipation hole 703 corresponding to the first heat dissipation hole 503; the first heat dissipation hole 503, the second heat dissipation hole 703 and the heat dissipation channel 731 are connected. Regarding the heat dissipation of the biaxial motor 600, it is necessary to use the air flow flowing out from the through hole 702 to take away the heat through the air flow. Specifically, when the air flow flows in from the through hole 702 Finally, on the one hand, it can flow through the second air guide groove 802, and some of it will enter the heat dissipation channel 731 from the inclined hole 732 to increase the flow velocity of the gas in the heat dissipation tube 730, and the heat of the biaxial motor 600 The first heat dissipation hole 503 can enter into the heat dissipation channel 731 through the second heat dissipation hole 703 , and the air flow through it is taken away at the right side port of the heat dissipation channel 731 to realize effective heat dissipation of the biaxial motor 600 .

In this case, a housing 900 is also included, which is fixedly installed on the air outlet cover 200, and the guide 800 is fixedly installed on the housing 900. A groove 901 is provided on the outer wall of the left end of the housing 900; the inner wall of the groove 901 is fixedly installed on the rotating part. The convex strips 704 on the outer wall of the right end of the housing 700 are inserted into each other and keep sliding fit; the middle part of the right end of the housing 900 is provided with a through hole corresponding to the outlet of the right end of the cooling tube 730. To isolate the two airflows and reduce the generation of turbulent flow, specifically, the gap formed between the outer wall of the casing 900 and the inner wall of the air outlet chamber 201 can effectively transmit the airflow transmitted through the first fan blade set 710, The inner wall of the housing 900 can effectively limit the flow trajectory of the airflow gushing out from the first air guiding groove 801, the second air guiding groove 802, and the heat dissipation channel 731, and finally gushes out from the outlet at the right end of the gas flow. When gushing out, the circulation track of the airflow can be effectively limited to ensure efficient blowing.
