On the described cabinet outer wall or inwall be provided with heat-insulation layer.
Described direct ventilation heat radiation air outlet is or/and direct ventilation heat radiation air inlet is provided with rain cover.
The utility model adopts the direct ventilation air inlet that dispels the heat is arranged on cabinet top or top, avoids the bottom air inlet of high temperature, make from the inspiration of direct ventilation heat radiation air inlet comparatively cool air the device in the cabinet is lowered the temperature.And the main air duct that direct ventilation heat radiation air inlet and direct ventilation heat radiation air outlet form between the two covers all devices that the cabinet domestic demand is dispelled the heat, be that direct ventilation heat radiation air inlet and direct ventilation heat radiation air outlet are positioned at the device both sides that need heat radiation, make the moving air of the suction device of flowing through, the heat on the device is taken away.The utility model is simple in structure, the energy efficiently radiates heat.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
Embodiment 1, as shown in Figure 1, a kind of direct ventilation heat radiation outdoor cabinet comprises cabinet 1, and cabinet 1 is provided with direct ventilation heat radiation air inlet 4 and direct ventilation heat radiation air outlet 8, described direct ventilation heat radiation air inlet 4 is arranged on cabinet 1 top or top, and present embodiment is arranged on cabinet 1 upper portion side wall.In direct ventilation heat radiation air inlet 4 or direct ventilation heat radiation air outlet 8 or the main air duct that forms between the two, be provided with and be used for force ventilated blower fan, because main air duct is the air flow passage that blower fan air-supply or exhausting form, this main air duct is relevant with device 9 arrangement modes, be that direct ventilation heat radiation air inlet 4 and direct ventilation heat radiation air outlet 8 will divide device 9 both sides that are located at the needs heat radiation, making wind energy flow through needs the device 9 of heat radiation, therefore, described main air duct need cover all devices 9 that will dispel the heat in the cabinet 1, just can reach the purpose of heat radiation.Direct ventilation heat radiation air inlet 4 is arranged on top or top, and this direct ventilation heat radiation air inlet 4 is with respect to the face of land, and temperature is low.For direct ventilation heat radiation air outlet 8, as long as energy main air duct radiator cover spare 9, then its position is indefinite.Preferably direct ventilation heat radiation air outlet 8 is arranged on cabinet 1 bottom or bottom.Present embodiment is arranged on direct ventilation heat radiation air outlet 8 on cabinet 1 lower sides.In order to prevent the temperature in the cabinet 1 outer temperatures involved cabinet 1, therefore in cabinet 1, be provided with heat-insulation layer 3, heat-insulation layer 3 also can be arranged on outside the cabinet 1 except being arranged in the cabinet 1, and applying cabinet outer wall is provided with.Be used for isolated environment high temperature, simultaneously layer of reflective material 2 can also be set, be used for just sunlit radiant heat and intercept, prevent that its direct transmission from influencing cabinet 1 inside.Layer of reflective material 2 is selected and can be made by the higher material of reflectivity, for example aluminium foil.
Blower fan 7 can be arranged in the air channel in the cabinet 1, also can be arranged in the cabinet 1 at direct ventilation heat radiation air inlet 4 or direct ventilation heat radiation air outlet 8 places or outside the cabinet 1, blower fan 7 can be that to blow also can be exhausting, being arranged on direct ventilation heat radiation air inlet 4 places is air-supplies, is arranged on direct ventilation heat radiation air outlet 8 places and then is exhausting.The type of blower fan 7 can require to select according to reality heat radiation, dispels the heat can select conventional fan for use when less demanding, and heat radiation requires height then can select high-power axial flow blower etc.Blower fan 7 can be selected two-way blower fan, when surface temperature is low, existing direct ventilation heat radiation air outlet 8 is become air inlet, and direct ventilation heat radiation air inlet 4 has become air outlet, and Cryogenic air is sent into cabinet 1 heat radiation.
In addition, for dustproof, waterproof, then in main air duct, be provided with waterproof ventilated membrane 5, Air Filter 6.Waterproof ventilated membrane 5, Air Filter 6 can two kinds all be provided with, and also can only be provided with a kind of.The position that is provided with will near or directly be fixed on direct ventilation heat radiation air inlet 4 and direct ventilation heat radiation air outlet 8, wherein waterproof ventilated membrane 5, Air Filter 6 mainly are provided with at direct ventilation heat radiation air inlet 4 places, have dust when preventing air intake, also waterproof when rainy.Waterproof ventilated membrane 5 can be selected the GORE film for use.
Embodiment 2, as shown in Figure 2, on the basis of embodiment 1, the position of direct ventilation heat radiation air inlet 4 remains unchanged, and being arranged on cabinet 1, direct ventilation heat radiation air outlet 8 is arranged on cabinet 1 top or top, because direct ventilation heat radiation air inlet 4, direct ventilation heat radiation air outlet 8 all is arranged on cabinet 1 top or top, then need be connected with the auxiliary air channel 10 of downward wind-guiding at the heat radiation of the direct ventilation in the cabinet 1 air inlet 4, described auxiliary air channel 10 is separated out by dividing plate 12, its upper end is connected with direct ventilation heat radiation air inlet 4, the space UNICOM of bottom or bottom in lower end and the cabinet 1, air intake is introduced cabinet 1 bottom, discharge from direct ventilation heat radiation air outlet 8 again behind the device 9 in the cabinet 1 of flowing through.Except in main air duct, being provided with waterproof ventilated membrane 5, the Air Filter 6 as shown in Example 1, in auxiliary air channel 10, also be provided with at least a in waterproof ventilated membrane 5, the Air Filter 6 near direct ventilation heat radiation air inlet 4.
The direct ventilation heat radiation air outlet 8 of present embodiment is arranged on cabinet 1 top.For rainproof, be provided with rain cover 11 at direct ventilation heat radiation air inlet 4 and direct ventilation heat radiation air outlet 8 places, be used for rain cover and enter cabinet 1 from direct ventilation heat radiation air inlet 4 and direct ventilation heat radiation air outlet 8, rain cover 11 can be the cover body that is provided with separately outside cabinet 1, also can be the shutter in direct ventilation heat radiation air inlet 4 and the setting of direct ventilation heat radiation air outlet 8 places.All the other structures do not repeat them here with embodiment 1.
