Abstract
The utility model discloses a low pressure pull-out type cubical switchboard with dustproof function of cooling, including the cabinet body, cooling chamber, compressor, condenser, evaporimeter, refrigerant pipeline, cabinet body rear side bottom is provided with the cooling chamber, be provided with compressor and condenser in the cooling chamber, cabinet body rear side upper portion is provided with the evaporimeter, compressor, condenser, evaporimeter pass through the refrigerant pipeline and link to each other. The utility model discloses a circulated refrigerant cools off the cabinet body between compressor, condenser, evaporimeter, need not to introduce the outside air, and the cooling effect is good, prevents effectively that external dust from getting into the internal portion of cabinet.
Description
Technical Field
The utility model relates to a power equipment technical field specifically is a low pressure pull-out type cubical switchboard that radiating effect is good.
Background
The external line of the switch cabinet enters a main control switch in the cabinet and then enters a branch control switch, and each entry is set according to the requirement. The low-voltage draw-out switch cabinet is mainly used for opening, closing, controlling and protecting electric equipment in the process of generating electricity, transmitting electricity, distributing electricity and converting electric energy of an electric power system.
Current low pressure pull-out type cubical switchboard mostly uses the forced air cooling mode to dispel the heat, it can be internal with outside air suction cabinet to adopt the forced air cooling heat dissipation, because pull-out type cubical switchboard is equipped with a plurality of unit drawers, the inner structure is complicated, make the dust in the air detain in cabinet internal portion easily, cover on the components and parts surface, dust is rubbed mutually by the effect of air current, produce static easily, influence power consumption safety, if use the air inlet filter core to filter dust, the filter core blocks up gradually in the use, influence the radiating effect, need periodic replacement, the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a low pressure pull-out type cubical switchboard with dustproof function of cooling, it has good radiating effect, and effectively prevents external dust to get into the cabinet body.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a low pressure pull-out type cubical switchboard with dustproof function of cooling, includes the cabinet body, cooling chamber, cabinet body rear side bottom is provided with the cooling chamber, be provided with compressor and condenser in the cooling chamber, cabinet body rear side upper portion is provided with the evaporimeter, compressor, condenser, evaporimeter pass through refrigerant pipe connection and communicate with each other.
Preferably, the surface of the condenser is provided with a heat radiation fan.
Preferably, the cabinet body is in a closed state when the cabinet door is closed, and the rear part of the cooling chamber is provided with heat dissipation holes and communicated with the outside.
Preferably, a refrigerant is circulated in the refrigerant line.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model discloses be provided with the cooling chamber, the cooling chamber communicates with each other through the louvre with external atmosphere, does not have gas exchange between the cabinet body and the cooling chamber, and the back is closed to the cabinet door, and the cabinet body is in airtight state, stops the dust entering cabinet body in the outside air.
2. The utility model discloses a set up compressor, evaporimeter, condenser, refrigerant pipeline, make the heat of the internal portion of cabinet absorb by the refrigerant in the refrigerant pipeline, the refrigerant is released heat through compressor and condenser after returning the cooling chamber, and the radiator fan on condenser surface arranges the heat to the external world, and the refrigerant after the cooling gets back to the evaporimeter once more through the refrigerant pipeline and absorbs the heat, and whole in-process refrigerant does not produce the loss, and the maintenance cost is low.
