Abstract
The utility model aims to provide a heat radiation switch cabinet and solves a problem of heat radiation of the switch cabinet. The heat radiation switch cabinet comprises a heat radiation switch cabinet body, wherein a bottom portion and a top portion of the heat radiation switch cabinet body are respectively provided with heat radiation holes. The heat radiation switch cabinet is characterized in that the top portion of the heat radiation switch cabinet body is further provided with a fan, air inlets of the fan face towards an inner portion of the switch cabinet, and the air inlets are provided with a spiral line-like air inlet pipe. When the heat radiation switch cabinet is at work, the fan starts and provides power to force air circulation in the switch cabinet; compared with natrual convection current, the air speed is substantially increased because of the fan, so a heat radiation speed is obviously accelerated, what is more important, the spiral line-like air inlet pipe is arranged at the air inlets of the fan, air eddy is formed in the switch cabinet, and inner corners of the switch cabinet can be influenced, and a heat radiation effect is better improved.
Description
Technical field
The utility model belongs to technical field of electricity, specially refers to a kind of switch cubicle.
Background technology
Electronic modular unit in the switch cubicle can produce a large amount of heat when work, must in time dissipate, otherwise can cause that the temperature in the switch cubicle rises, and affects the electronic modular unit normal operation.Traditional switch cubicle all is to establish louvre at sidewall, utilize free convection to dispel the heat, and the scope of the convection current wind effect of vertical direction is very little, so its radiating effect is limited.
The utility model content
The purpose of this utility model is to propose a kind of heat radiation switch cubicle, to solve the heat dissipation problem of switch cubicle.
Heat radiation switch cubicle of the present utility model comprises the switch cubicle body, bottom and the top of described switch cubicle body are equipped with louvre, key is that the top of switch cubicle body also is provided with blower fan, and the air inlet of described blower fan is towards inside switch cabinet, and the air inlet place is provided with the blast pipe of zigzag shape.
When work, start blower fan, provide power by blower fan, force the circulation of air in the switch cubicle, than free convection, wind speed has remarkable lifting, so radiating rate can obviously be accelerated.The more important thing is, because the air inlet place of blower fan is provided with the blast pipe of zigzag shape, therefore so that the interior air eddy that forms of switch cubicle can have influence on the corner in the switch cubicle, more promoted radiating effect.
Further, the sidewall of described switch cubicle body is provided with the auxiliary air inlet that aperture from top to bottom increases gradually, can suck from the side fresh cold air like this, improve radiating effect, in addition, the aperture of auxiliary air inlet from top to bottom increases gradually, can guarantee that like this electronic modular unit of bottom also obtains sufficient cooling.
Switch cubicle of the present utility model has enlarged the heat radiation scope by changing the circulation of air mode in the switch cubicle, has improved radiating effect, has good practicality.
Description of drawings
Fig. 1 is the structural representation of heat radiation switch cubicle of the present utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the heat radiation switch cubicle of present embodiment comprises switch cubicle body 1, bottom and the top of switch cubicle body 1 are equipped with louvre, key is that the top of switch cubicle body 1 also is provided with blower fan 2, the air inlet of described blower fan 2 is towards inside switch cabinet, and the air inlet place is provided with the blast pipe 3(louvre not shown in FIG. of zigzag shape).
When work, start blower fan 2, provide power by blower fan 2, force the circulation of air in the switch cubicle 1, than free convection, wind speed has remarkable lifting, so radiating rate can obviously be accelerated.The more important thing is, because the air inlet place of blower fan 2 is provided with the blast pipe 3 of zigzag shape, therefore so that switch cubicle 1 interior formation air eddy can have influence on the corner in the switch cubicle 1, more promoted radiating effect.
In addition, the sidewall of switch cubicle body 1 is provided with the auxiliary air inlet 4 that aperture from top to bottom increases gradually, can suck from the side fresh cold air like this, improve radiating effect, in addition, the aperture of auxiliary air inlet 4 from top to bottom increases gradually, can guarantee that like this electronic modular unit of switch cubicle bottom also obtains sufficient cooling.
