Arranging further: described cabinet is internally provided with spiral board, and described spiral board is arranged between air inlet and air outlet, described spiral board and cabinet detachably connect.
So arrange, when the cold air of air inlet enters cabinet inside, owing to the air outlet on cabinet top makes the cold air of bottom flow up, by internal spiral board, owing to spiral board is the blade of tilting screw, the cold air come up in bottom is made to produce the flow effect of eddy flow shape through spiral board, cold air is made to be evenly distributed in the inside of cabinet, and then make the electric fittings within cabinet cool down uniformly, while spiral board, also the air making inside produces certain wind-force, accelerates the mobility of its inner air, strengthens its radiating effect；Spiral board is removably connected to inside cabinet, by mobile spiral board, it is possible to regulate the space size between spiral board.
Arrange further: being provided with the bracket for placing spiral board on the inwall of described side plate in pairs, multiple described paired brackets are uniformly arranged along cabinet short transverse.
So arrange, by the bracket arranged on cabinet, make spiral board stable be arranged at inside cabinet, multiple change spiral boards prevent the position on differing heights on paired bracket, in order to prevent different size of electric fittings, improve its usability.
Arrange further: described air inlet and air outlet are equipped with drainage screen.
So arranging, drainage screen is possible to prevent some external impurity to enter air inlet, it is prevented that some insecticides fly into inside cabinet, causes the fault that the electric fittings of inside causes some unnecessary.
Arrange further: described side plate is provided with for preventing rainy weather water droplet from invading the rain visor of air inlet and air outlet towards the outer face of cabinet, and the described bottom towards cabinet tilts rain visor and arranges.
So arrange; when rain visor is possible to prevent to rain, rainwater falls to cabinet portion from air inlet or gas outlet; being effectively protected the safety in utilization of internal electric fittings, also functioned to a certain extent block dust-proof effect, being obliquely installed can so that rainwater drops smoothly.
By adopting technique scheme, this utility model hinge structure is compared: by being provided with a downward-sloping deflector in the upper end of air inlet, and between air inlet and air outlet, it is provided with spiral board, cold air is made to be evenly distributed in the inside of cabinet, and then make the electric fittings within cabinet cool down uniformly, it is to avoid the electric fittings local heating of air inlet and the problem that causes shortening the service life of electric fittings.
