Embodiment Construction

[0041] figure 1 It is a structural diagram of a method shown in an exemplary embodiment of the present invention.

[0042] like figure 1 As shown, the ventilation device provided in this embodiment includes: a grill 1 and a filter 2 , and the filter 2 is arranged in the grill 1 .

[0043] Wherein, the grid 1 may have multiple grids. For example, multiple vertical ribs can be set to form multiple identical grids arranged in the horizontal direction, and multiple horizontal ribs can be set to form multiple identical grids arranged in the vertical direction, and horizontal ribs and vertical ribs can also be set at the same time , forming multiple grids arranged horizontally and vertically. In this embodiment, the grid size of the grid 1 is not limited, and it can be specifically limited according to actual needs. For example, the grid 1 is used to prevent birds and other animals from touching the filter screen 2, so the mesh of the grid 1 can be set to a size that can block t...

Abstract

The invention provides a ventilation device. The ventilation device comprises a grille and a filter net, wherein the filter net is disposed in the grille. The grille is fixedly mounted at a vent of the device to be ventilated; a chute is disposed in the grille, and at least one side of the grille is provided with an opening to allow the filter net to slide out of the opening through the chute. Theventilation device provided by the invention can conveniently take out the filter net and can solve the technical problem that the ventilation net is not easy to disassemble in the prior art.

Description

technical field [0001] The invention relates to ventilation equipment technology, in particular to a ventilation device, which belongs to the field of mechanical engineering. Background technique [0002] With the development of the domestic power industry, various power electronic converters play an increasingly important role in industry, agriculture, military and transportation industries, such as converters, which can make the voltage, frequency, phase number and Other quantities or characteristics change, so the converter becomes a very important device in the power system. [0003] However, the converters with higher power have serious heat generation phenomenon, which requires adding radiators and cooling fans in the converters. After the air outside the converters enters the converters under the action of the cooling fan, Cool the radiator, thereby speeding up the heat dissipation of the radiator. However, due to impurities such as dust in the external air, if thes...
