Military electromagnetic shielding ventilation device provided with open fixed louver

Abstract

The invention discloses a military electromagnetic shielding ventilation device provided with an open fixed louver. The device comprises the open fixed louver, a dust-proof device, a forced ventilation device, an electromagnetic shielding net and a rear casing, wherein the dust-proof device is of a sandwich structure formed by a dust-proof screen mesh, dust-proof cotton and a dust-proof net, the forced ventilation device comprises a fan mounting plate and an axial flow fan, and the electromagnetic shielding net is mounted on the rear casing through a net pressing frame; and the open fixed louver comprises a window frame and rectangular louver blades, multiple first ventilation openings are formed in the front side surface of the window frame, a louver blade fixing plate is arranged on eachof left and right sides of each first ventilation opening, multiple paired fixing grooves are formed in the louver blade fixing plates on two sides of the first ventilation openings from top to bottom, and two ends of the rectangular louver blades are fixed in the fixing grooves of the two louver blade fixing plate. The device meets the requirements of high cleanliness and ventilation quantity while guaranteeing an electromagnetic shielding function, has high ventilation quantity and good structural reliability and is convenient and fast to maintain.

Description

technical field [0001] The invention belongs to the field of electromagnetic shielding, and relates to an electromagnetic shielding ventilator, in particular to a military electromagnetic shielding ventilation device with an open fixed louver. Background technique [0002] Military equipment has extremely strict requirements on electromagnetic shielding, especially for radar vehicles and related equipment. With the requirements of informatization, various equipment with different requirements have different requirements for ventilation shielding. For example, some equipment is intermittently turned on, so it needs Venetian shutters, some equipment need to be kept open normally. Although these equipments do not generate much heat, with the development of science and technology, higher requirements are put forward for the cleanliness of the air inside the equipment. The electromagnetic shielding equipment and forced Ventilated electromagnetic shielding equipment can no longer ...
