Fan for air cooler

Abstract

The invention discloses a fan for an air cooler. The fan comprises a machine body, a rack and a protection assembly. The rack is fixed to the bottom of the machine body, the front and back ends of themachine body are detachably provided with protection net plates, the protection assembly is detachably arranged on the machine body in a sleeving manner, the protection assembly comprises supportingconnecting rods, movable plates, movable springs and arc protection rods, the movable plates are horizontally arranged on the front and the back of the machine body, the two supporting connecting rodsare perpendicularly and horizontally located on the left and the right of the machine body, two ends of the supporting connecting rods penetrate through the movable plates to be exposed to the outerside, and the ends are provided with limiting blocks. The movable springs are arranged on the outer surfaces of the extending ends of the supporting connecting rods in a sleeving manner, and two endsof the movable springs are fixed to the opposite faces o the limiting blocks and the movable plates. The protection assembly is arranged, the surface can be protected when the fan is wholly stored orcarried, the damage probability of bump of the surface can be reduced, the service life is indirectly prolonged, meanwhile, the whole fan is convenient to mount and dismount, use is convenient, and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of fans for air coolers, in particular to a fan for an air cooler, in particular to an axial flow fan for an air cooler. Background technique [0002] The air cooler is a device that uses ambient air as the cooling medium and sweeps the outside of the finned tube to cool or condense the high-temperature process fluid in the tube. It is referred to as "air cooler" or "air-cooled heat exchanger". The air cooler is also called the fin fan, which is often used to replace the cooling medium of the water-cooled shell-tube heat exchanger. The fan is an axial flow fan with large air volume, low noise and low power. The flow fan is the airflow in the same direction as the axis of the fan blade, such as an electric fan, and the fan of the external unit of the air conditioner is an axial flow fan. It is called "axial flow" because the gas flows parallel to the shaft of the fan. [0003] During the storage or handlin...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fan for an air cooler to solve the problem that the surface of some axial flow fans proposed in the above background technology is prone to paint peeling or damage due to bumps during storage or transportation, which not only affects the appearance, but also is prone to rust. The problem of reducing its service life due to rust wear
