Abstract
The utility model proposes low-tension switch cabinet from thermophilic bimetallic shutter.The lower housing portion of cabinet laterally has some strip air vents, there is bimetallic louvre blade outside each air vent, the thickness direction of bimetallic louvre blade inlays an outer layer metal piece, the thermal coefficient of expansion of bimetallic louvre blade is more than the thermal coefficient of expansion of outer layer metal piece, position and the size of bimetallic louvre blade: bimetallic louvre blade can cover air vent after trailing.By bimetallic louvre blade will be arranged outside air vent, when being raised by the gas flow temperature from environment of bimetallic louvre blade, the expansion of bimetallic louvre blade is more than outer layer metal piece, bimetallic louvre blade is bent outwardly, open passage, stronger ventilation area, otherwise, bimetallic louvre blade gradually extends closedown passage, can actively adapt to the change of environment temperature and change air flux, and be not necessarily to external impetus, use the inserted outer layer metal piece in local, nonferrous materials can be saved, reduce cost.
Description
Technical field:
The utility model relates to low-tension switch cabinet technical field, is specifically related to low-tension switch cabinet from thermophilic bimetallic blinds
Window.
Background technology:
Low-tension switch cabinet typically bottom and top be provided with passage for produce convection current to cabinet in electrical equipment fall
Temperature, the passage using at present is substantially fixed, and passage secures, and the cooling capacity of a low-voltage distribution cabinet is also just fixing
, it is impossible to adapt to the change in season, can only change with the change of ambient temperature.
Utility model content:
In order to solve the problems referred to above, the utility model is directed to a kind of low-tension switch cabinet from thermophilic bimetallic shutter.
The technical solution of the utility model is: low-tension switch cabinet is from thermophilic bimetallic shutter, including cabinet, the shell of cabinet
Body lower, transverse has some strip air vents, and outside each air vent, relevant position is fixed with bimetallic louvre blade, double
On the waist location of metal louvres piece, air vent at edge, the thickness direction of bimetallic louvre blade inlays an outer layer metal piece, double
The thermal coefficient of expansion of metal louvres piece is more than the thermal coefficient of expansion of outer layer metal piece, and position and the size of bimetallic louvre blade exist
Air vent can be covered after: bimetallic louvre blade trails.
The utility model has the advantages that low-tension switch cabinet is located at low-tension switch cabinet from thermophilic bimetallic shutter
Bottom be used for switch cubicle air intake, by bimetallic louvre blade will be arranged outside air vent, when by bimetallic louvre blade
When the gas flow temperature of environment raises, the expansion of bimetallic louvre blade is more than the (thermal expansion of bimetallic blinds of outer layer metal piece
Coefficient is more than the thermal coefficient of expansion of outer layer metal piece), bimetallic louvre blade is bent outwardly, and opens passage, stronger ventilation area,
Strengthen cooling extent, otherwise, when ambient air temperature declines, bimetallic louvre blade gradually extends closedown passage, electric in keeping cabinet
Gas element manipulation temperature, can actively adapt to the change of environment temperature and change air flux, and is not necessarily to external impetus, employing office
The bimetallic louvre blade form of portion's inserted outer layer metal piece, can save nonferrous materials, reduces cost.
Brief description:
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is operating diagram of the present utility model.
1-cabinet in figure, 2-bimetallic louvre blade, 3-air vent, 4-outer layer metal piece.
Detailed description of the invention:
The utility model is described in further detail below in conjunction with the accompanying drawings:
Being combined shown in Fig. 2 by Fig. 1, low-tension switch cabinet is from thermophilic bimetallic shutter, including cabinet 1, under the housing of cabinet 1
Portion laterally has some strip air vents 3, and outside each air vent 3, relevant position is fixed with bimetallic louvre blade 2, at double gold
On the waist location of genus louvre blade 2, air vent 3 at edge, the thickness direction of bimetallic louvre blade 2 inlays an outer layer metal piece 4,
The thermal coefficient of expansion of bimetallic louvre blade 2 more than the thermal coefficient of expansion of outer layer metal piece 4, the position of bimetallic louvre blade 2 and big
It little is: bimetallic louvre blade 2 can cover air vent 3 after trailing.
Low-tension switch cabinet is located at the bottom of low-tension switch cabinet for switch cubicle air intake from thermophilic bimetallic shutter, by will
Bimetallic louvre blade 2 is set outside air vent 3, when being raised by the gas flow temperature from environment of bimetallic louvre blade 2,
More than outer layer metal piece 4, (thermal coefficient of expansion of bimetallic louvre blade 2 is more than outer layer metal piece 4 in the expansion of bimetallic louvre blade 2
Thermal coefficient of expansion), bimetallic louvre blade 2 is bent outwardly, and opens air vent 3, stronger ventilation area, strengthens cooling extent, otherwise,
When ambient air temperature declines, bimetallic louvre blade 2 gradually extends and closes air vent 3, keeps electrical equipment operating temperature in cabinet, energy
Enough actively adapt to the change of environment temperature and change air flux, and be not necessarily to external impetus, use the inserted outer layer metal in local
The bimetallic louvre blade form of piece, can save nonferrous materials, reduces cost.
