Wet curtain missing installation protective structure and tower type cooling fan

Abstract

The invention discloses a wet curtain missing installation protective structure and a tower type cooling fan. The wet curtain missing installation protective structure comprises a rear shell, a wet curtain, a water receiving tank and an inductive switch. The rear shell comprises an installation groove. The wet curtain is detachably installed on the rear shell and seals the open end of the installation groove. A water supply opening which is used for supplying water to the wet curtain is formed in the installation groove. The water receiving tank is arranged in the installation groove, is controlled by a driving mechanism to move and has a first state and a second state. When the water receiving tank is located in the first state, the water receiving tank is arranged in the mode of gettingclose to the water supply opening. When the water receiving tank is located in the second state, the water receiving tank is arranged in the mode of keeping away from the water supply opening. The inductive switch is arranged on the wet curtain and / or the rear shell, is used for detecting whether the wet curtain is installed or not, and controls the driving mechanism. The cooling fan without the installation of the wet curtain works, the water which flows out of the water supply opening enters the water receiving tank, the water receiving tank collects the water which flows out, the water is prevented from invading the interior of the cooling fan, and the work of circuits of the cooling fan is protected against the influence; the degree of collision between the water flow and the water receiving tank is obviously reduced, and the working noise of the cooling fan is obviously lowered.

Description

technical field [0001] The invention relates to the technical field, in particular to a wet curtain leakage protection structure and a tower cooling fan. Background technique [0002] At the air inlet of the evaporative cooling fans currently on the market, there will be a device that absorbs water and increases the contact area between water and air to increase the evaporation of the machine - a wet curtain. At the same time, it can also avoid water flowing down the water separation structure. It is sucked into the fan, but there is a situation in the wet curtain structure of the existing cooling fan, that is, the fan can still be started without installing the wet curtain, but at this time, if the cooling fan is in working condition, the water flowing down after the cooling fan sucks water Water splashing on the motor has potential electrical safety hazards; it will also generate relatively loud noises. Contents of the invention [0003] Therefore, the technical problem...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the cooling fan in the prior art is not equipped with a wet curtain, which may easily cause electrical safety hazards, thereby providing a protective structure for missing a wet curtain and a tower cooling fan.
