Description
Technical field
The utility model is related to a kind of circuit arrangement, more particularly to a kind of positive draft power control cabinet.
Background technology
The in vivo electric elements of power control cabinet cabinet such as frequency converter, breaker etc. can generate heat in the process of running generates heat, makes
In-cabinet temperature raises, and the excessively high accidents such as fire hazardous of holding of temperature occur.Therefore, it is necessary to reduce the cabinet of power control cabinet operationally
Interior temperature, this requires power control cabinet must possess good heat sinking function.At present, power control cabinet heat dissipation generally use from
The measures such as right ventilating and cooling mode or the air-draft-type forced ventilation using general fashion.The gravity-flow ventilation type of cooling is in heating electric appliance
During element manipulation, heat dissipation effect is bad, and it is excessively high to be easy to cause automatically controlled in-cabinet temperature, reduces the cabinet interior insulation materials'use service life or compels
Heating electric appliance element is made to stop transport；Forced ventilation measure under general fashion be mostly opened up in power control cabinet cabinet lower part air inlet hole,
Radiator fan is set at the top of cabinet, so that power control cabinet keeps good ventilation and heat function.Although this cooling measure can be with
The heat dissipation problem of electric elements is effectively solved, but due to being constantly in open state at the radiator fan mounting hole of cabinet top, and
Due to the in vivo subnormal ambient of cabinet so that dust can be easily accessible by gaps such as power control cabinet openings in power control cabinet simultaneously easily attached
It on electric appliance original paper or accumulation is on radiator fan, damage the electric elements accelerated ageing in radiator fan and power control cabinet.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of positive draft power control cabinets, realize the positive pressure in power control cabinet
Ventilation and heat.
The utility model positive draft power control cabinet, including cabinet, the top of the cabinet is equipped with air inlet hole, the air inlet hole
Air inlet deflector, air air intake filter and air inlet fan, the lower part of the cabinet is inside sequentially installed with from top to bottom to be equipped with out
Air holes is sequentially installed with outlet air deflector and outlet air filter screen in the exhaust vent from outside to inside.
The utility model positive draft power control cabinet, wherein the exhaust vent is located on the front of the cabinet lower part.
The utility model positive draft power control cabinet, wherein the exhaust vent is located on the side of the cabinet lower part.
The utility model positive draft power control cabinet, wherein the exhaust vent is located on the bottom surface of the cabinet lower part.
The utility model positive draft power control cabinet difference from prior art is that the utility model positive draft is automatically controlled
Air is sent into the cabinet of power control cabinet by cabinet by the air inlet fan at top, and positive pressure is remained in cabinet, can effectively prevent ash
Dirt is entered by cabinet gap in power control cabinet, is sent out into the in vivo air of cabinet from the exhaust vent of cabinet lower part, so as to fulfill electricity
Control the positive draft heat dissipation in cabinet.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the front view of the utility model positive draft power control cabinet；
Fig. 2 is the right view of the utility model positive draft power control cabinet；
Fig. 3 is the top view of the utility model positive draft power control cabinet.
Specific embodiment
As shown in Figure 1, and with reference to shown in Fig. 2,3, the utility model positive draft power control cabinet includes cabinet 10, the cabinet
10 top is equipped with air inlet hole 9, is sequentially installed with air inlet deflector 3, air air intake filter in the air inlet hole 9 from top to bottom
2 and air inlet fan 1, the lower part of the cabinet 10 is equipped with exhaust vent 8, and outlet air is sequentially installed with from outside to inside in the exhaust vent 8
Deflector 4 and outlet air filter screen 5.
The utility model positive draft power control cabinet, according to actual demand, wherein the exhaust vent 8 can be located at the cabinet
On the fronts of 10 lower parts, side or bottom surface.
Air is sent into the cabinet 10 of power control cabinet by the air inlet fan 1 at top by the utility model positive draft power control cabinet
It is interior, positive pressure is remained in cabinet, can effectively prevent dust from entering by cabinet gap in power control cabinet, the sky into cabinet 10
The exhaust vent 8 of gas from 10 lower part of cabinet is sent out, so as to fulfill the positive draft heat dissipation in power control cabinet.
The utility model positive draft power control cabinet, the outer casing underpart of cabinet 10 are provided with exhaust vent 8, are set at exhaust vent 8
There are outlet air deflector 4 and outlet air filter screen 5；The top of cabinet 10 offers air inlet hole 9, and air inlet hole 9 is provided simultaneously with installation air inlet
Fan 1 and the function of taking on air inlet hole are provided with air air intake filter 2 and air inlet deflector 3 at air inlet hole 9.Air inlet fan 1
During work, after the air air intake filter 2 that cold wind passes through top, the mode dried from air inlet fan 1 into power control cabinet is blown, electricity
Positive pressure is remained in control cabinet cabinet, and avoiding power control cabinet, ambient dust caused by due to poorly sealed etc. enters switch board
Situation.
Display screen 6 and operation button 7 are additionally provided in positive draft power control cabinet, be respectively used to show and is operated.
The utility model positive draft power control cabinet has following technique effect：
(1) there is forced ventilation, can effectively reduce power control cabinet in-cabinet temperature；
(2) when power control cabinet is run, positive pressure is remained in cabinet, it is automatically controlled can effectively to prevent that dust from being entered by cabinet gap
In cabinet；
(3) during power control cabinet is stopped transport, the filter device that is set at air inlet and lower air outlet at the top of power control cabinet can be with
Remaining valid prevents dust from entering in power control cabinet；
(4) air outlet may be mounted at the proper sites such as power control cabinet front, side, bottom surface.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
