Description

Technical Field

[0001] This utility model relates to the field of air-cooled quiet air conditioning unit technology, and in particular to an air-cooled quiet air conditioning unit with axial flow fan for heat dissipation. Background Technology

[0002] In existing technologies, such as Figure 1 As shown, a centrifugal fan is fixed coaxially with the rotor at the end cover of the air-cooled silencing unit, which is close to the rotor. Because the centrifugal fan also expels the air, which is used as a heat transfer medium inside the air-cooled silencing unit, into the base at the end close to the rotor, when the first fan and the centrifugal fan operate simultaneously, due to their identical function, there is a pulling force inside the air-cooled silencing unit, which greatly consumes power. This manifests as the air-cooled silencing unit being unable to carry the load. For example, a unit that was originally 12KW can only carry 10KW, accompanied by black smoke. Furthermore, due to the pulling force inside the motor, the gas flow rate and density inside the unit are reduced, making it unable to remove enough heat, resulting in a higher motor temperature and a significant reduction in efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a wind-cooled quiet air handling unit with axial flow fan for heat dissipation, which improves the heat dissipation of the wind-cooled quiet air handling unit and increases its power.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a wind-cooled and quiet air-cooled unit with axial flow fan for heat dissipation, characterized in that it includes a base and a rotor and a rotating shaft disposed in the base, the rotor and the rotating shaft are coaxially fixed, a flow guide and an end cover are respectively fixed on both sides of the base, the rotating shaft and the flow guide are located on the same side, and a first fan is fixedly disposed at the end of the rotating shaft.

[0005] Furthermore, several flow channels are provided within the base along the length of the base.

[0006] Furthermore, a through hole is provided at the center of the air guide shroud for the shaft to extend out, and the first fan is coaxially fixed with the shaft on the side of the air guide shroud away from the base.

[0007] Furthermore, several air inlets are provided on the end cap.

[0008] Compared with the prior art, the beneficial effects of this utility model include: by eliminating the centrifugal fan, the unit only has the first fan to assist the gas flow inside the base. The airflow direction inside the base is constant and there is no pulling force. At the same time, due to the presence of the first fan, cold air outside the base can enter the base from the end cover, thereby carrying away heat and reducing the temperature of the unit, thus improving efficiency.

[0012] The numbers in the diagram are: 1-base, 2-screw, 3-end cover, 4-first fan. Detailed Implementation

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0014] A type of air-cooled quiet air conditioning unit with axial flow fan for heat dissipation, such as Figure 2 As shown, it includes a base 1 and a rotor and a shaft disposed in the base 1. The rotor and the shaft are coaxially fixed and can rotate synchronously in the base 1. Several guide channels are opened in the base 1 along the length direction of the base 1. The guide channels are evenly distributed around the rotor. The arrangement of the guide channels can meet the air circulation inside the air-cooled silencing unit to complete the heat exchange.

[0015] To enhance airflow inside the base 1, a guide shroud 2 and an end cap 3 are fixedly installed on both sides of the base 1, respectively. The rotating shaft and the guide shroud 2 are located on the same side, and a first fan 4 is fixedly installed at the end of the rotating shaft. The first fan 4 is fixed coaxially with the rotating shaft, so that the rotating shaft can drive the first fan 4 to rotate synchronously, thereby exhausting the air used as a heat transfer medium inside the air-cooled unit into the base 1, allowing the cold air of the external refrigerant to enter, thus completing the air-cooling process. The presence of the first fan 4 can significantly enhance airflow inside the base 1.

[0016] It is worth mentioning that the centrifugal fan is not installed close to the rotor, because the centrifugal fan will also guide the air inside the air-cooled silent unit as a heat medium to the inside of the base 1 at one end close to the rotor. When the first fan 4 and the centrifugal fan operate at the same time, because their functions are the same, the air-cooled silent unit inside has a pulling force, which greatly consumes power, and the air-cooled silent unit cannot carry the load. For example, the original 12KW unit can only carry 10KW load, and is accompanied by black smoke phenomenon; and because of the pulling inside the motor, the gas flow inside the unit is reduced, the density is reduced, and enough heat cannot be taken away, so that the temperature of the motor is too high, and the efficiency is greatly reduced.

[0017] Therefore, by deleting the centrifugal fan, only the first fan 4 is used to assist the gas flow inside the base 1, the airflow direction inside the base 1 is constant, and there is no pulling force. At the same time, because of the existence of the first fan 4, the cold air outside the base 1 can enter the base 1 from the end cover 3, so as to take away the heat and reduce the temperature of the unit, thereby improving the efficiency. The air inlet opening formed on the end cover 3 can provide the condition for the external cold air as a coolant to enter. The fixed seat fixedly arranged on the outer edge of the flow guide cover 2 and the end cover 3 can solve the problem of fixing the unit.

[0018] The center of the aforementioned flow guide cover 2 is provided with a through hole for the extension of the rotating shaft. The first fan 4 is coaxially fixed with the rotating shaft on the side of the flow guide cover 2 away from the base 1.

[0019] The technical scope of the present application is not limited to the above description. Those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should be within the protection scope of the present application.
