Summary of the invention
The objective of the invention is provides a kind of anti-condensation electric component box to the problems referred to above, can prevent effectively that following of top condensate to electric equipment, prolonging the safety and reliability of electric equipment life-span and raising electric equipment operation.
The technical scheme that the present invention solves the problems of the technologies described above is: water collection sheet is equipped with in below, casing top, and said water collection sheet top is provided with several adjacent successively water guide grooves, and the top between the adjacent water guide groove has several air vent holes; Each air vent hole top is equipped with baffle plate, and the size of baffle plate can be blocked by the top at least and drop into the water droplet in the air vent hole, and said baffle plate is fixed on the water collection sheet upper end through support, makes that the gap between baffle plate below and the both sides water guide recess sidewall forms the exhaust passage.The humid air that rises can get into upper space along the air vent hole on the water collection sheet, and casing top condensation water is dropped on the water collection sheet and fall into the water guide groove, discharges or receive once more thermal evaporation by the water guide groove again.Because the air vent hole top is provided with baffle plate, thereby therefore top condensation water droplet can not drop in the air vent hole; The aperture of air vent hole is unrestricted; Large-size can be set, can rise to the top through water collection sheet apace to make things convenient for humid air, baffle plate can also prevent that air vent hole from stopping up because of laying dust.
Said water guide groove laterally arranges, and the baffle plate of all air vent hole tops, each top is made up of a whole baffle plate.The baffle plate of the water collection sheet of this structure and air vent hole top is made simpler, and draining is convenient.
The present invention is provided with baffle plate above the water collection sheet air vent hole at casing top, the aperture of air vent hole is increased, and not only permeability is good; And air vent hole is difficult for being stopped up by dust; Can adapt to and use, can effectively collect the water droplet that the top falls, thereby avoid being dropped on the electric equipment than wet environment; Can prolong electric equipment useful life, improve the safety and reliability of electric equipment operation.In addition, water collection sheet is processed and is installed very convenient.
