Problems solved by technology

[0003] For example, the motors on the large-scale motor direct-connected axial flow fans are independently installed in the motor mounting base of the above structure. Since the motor mounting base is a closed space, it is inevitable that the motor will generate certain noise after being used for a period of time. If the heat cannot be dissipated in time, it will affect the stable operation and service life of the motor

Embodiment 1

[0014] Embodiment 1: An axial flow fan with an independent air-cooling channel, the axial flow fan at least includes a cylinder, and several cold air inlet windows 1 are opened on the outer wall circumference of the cylinder, and the cold air inlet windows 1 It is connected with the airfoil guide vane 2 inside the barrel. The airfoil guide vane 2 is a hollow structure, and it communicates with the cold air inlet window 1 to form an air flow channel. The airfoil guide vane 2 communicates with the motor installation chamber 3, and the motor installation chamber 3 is opened on the housing at one end of the fan blade. There are ventilation windows4.

Embodiment 2

[0015] Embodiment 2: An axial flow fan with an independent air-cooling passage, wherein the cold air inlet window 1 corresponds to the airfoil guide vane 2 and is connected one by one, and the cold air inlet window 1 and the exhaust window The number of 4 is nine. The structures and connections of the remaining parts are the same as those described in the foregoing embodiments.

[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The invention discloses an axial flow fan with an independent air cooling channel, and belongs to the field of fans; the axial flow fan is used for cooling a fan motor and provided with cold air intake windows on the outer wall of the cylinder body of the axial flow fan; the cold air intake windows penetrate through hollow wing type guide vanes to form an air flow channel; the air flow channel penetrates with a motor installation chamber; and an air exhaust window is arranged at the tail of the motor installation chamber. In view of the above technical scheme, the axial flow fan provided by the invention can radiate the motor of a large-sized motor direct-connected axial flow fan effectively without adding other power.

Description

technical field [0001] The present application belongs to the field of fans, and in particular relates to an axial flow fan with an independent air-cooling channel. Background technique [0002] Axial flow fans can flow gas parallel to the direction of the fan shaft, and are usually suitable for occasions with high gas flow and low pressure requirements. Axial flow fans generally include a cylindrical outer shell of the fan, and guide vanes are welded inside the outer shell, and a motor installation room is installed and fixed on the guide vanes, and a motor for driving the fan blades to rotate is installed in the motor installation room. [0003] For example, the motors on large-scale motor direct-connected axial flow fans are all independently installed in the motor mounting base of the above structure. Since the motor mounting base is a closed space, it is inevitable that the motor will produce certain damage after being used for a period of time. If the heat cannot be d...
