Abstract

The invention provides a ventilating and rain retaining device used for a radar antenna array, which comprises a fixed frame and a louver, wherein, the louver comprises at least a leaf, each leaf of louver is installed in the fixed frame through a bending plate, the blade of the louver at the inner side of a wind inlet surface is horizontally installed, the blade of the adjacent louver is vertically installed, thus, the rain retaining rate is enhanced, cooling air can be entered and rain water can be retained whether being under the condition of forward direction and overturning 180 degrees, so that the heat generated by the electronic element and the immediate heat radiation are ensured; the blade with no installing surface can be conveniently installed, and can be firmly fixed; the circulating resistance of the air can be reduced through arranging a wing guiding surface, to increase the air disturbance, and to prevent the rain water from entering; the excessive entering amount of the rain water is effectively prevented through the rain wrapping surface; the rain retaining effect is further enhanced through the reasonable gap among the blades, therefore, the cost is saved. The device can effectively ventilate and retain the rain, to improve the safety performance of the electronic device, and prolong service life.

Description

technical field

[0001] The invention relates to a ventilation and rain-shielding device, in particular to a ventilation and rain-shielding device for a radar antenna front. Background technique

[0002] At present, most of the electronic cabinets are open cabinets. There is no cooling, cooling and dehumidification measures inside, and only local ventilation and heat dissipation are used. Most of the electronic cabinets installed on the antenna array do not take protective measures, or the protection is not in place. Electronic components Often soaked in rainwater and working in a harsh environment for a long time, unfavorable factors often lead to the deviation of the working state of the electronic components, which will seriously damage the electronic components and affect the reliability of the transmission system; in some closed cabinets, the heat cannot be dissipated in time , the temperature of electronic components rises sharply, the work is unstable, the life of comp...
