Abstract
The utility model discloses a forced-ventilated outdoor equipment cabinet based on cable trench air flow heat exchange, which comprises a cabinet body. An exhaust fan is arranged in the cabinet body. The forced-ventilated outdoor equipment cabinet is characterized in that an air inlet is arranged at the bottom of the cabinet body and is communicated with a cable trench. The forced-ventilated outdoor equipment cabinet is based on a cable trench air flow heat exchange technique. Air in the cable trench below the working site of the outdoor cabinet is used for heat dissipation, i.e. the air in the cable trench is absorbed into the outdoor cabinet from the air inlet at the bottom of the outdoor cabinet. The air intake method is a compensation for a regular air intake method. Thereby, the normal operation of electronic equipment in the cabinet can be ensured.
Description
Technical field
The utility model relates to a kind of outdoor cabinet, especially relates to the good outdoor cabinet of a kind of performance of ventilating
, belong to the electric cabinet technical field.
Background technology
Because outdoor cabinet in use, the outdoor cabinet temperature inside is subjected to causing temperature to raise from the thermal source influence of three aspects, one electric device that is mounted in rack inside generates heat because of work, the 2nd, the heating of the heater of working in order to prevent the inner condensation of rack, the 3rd, solar radiation is generated heat to the rack surface and is conducted rack inside.Rack inside is caused that by various heats temperature raises, and particularly in the summer of southern china, often temperature can surpass the heat-resistant limit of the inner institute of rack installation electric device.In order to realize the control to environmental index such as outdoor cabinet temperature inside, humidity, the mode of generally taking is the forced ventilation heat radiation.Concrete mode of operation is that the inner fan starting of rack with the fresh air inlet suction rack inside of the outer ozone of rack by cabinet sidewalls, substitutes the high temperature air of rack inside, and high temperature air is discharged outside the cabinet, and so forth.
Because the rack ambient air is affected by environment, such as high temperature, moisture, dust etc., and environmental change is big, unstable, and these all can influence the radiating effect of outdoor cabinet.
The utility model content
Technical problem to be solved in the utility model provides a kind of outdoor cabinet, can keep the temperature in the cabinet to be in the scope of requirement by forced ventilation effectively, guarantees the normal operation of cabinet inner electronic equipment.
For solving the problems of the technologies described above, the utility model provides a kind of forced ventilation outdoor cabinet based on the heat exchange of cable trough air flows, comprises cabinet, and ventilating fan is set in cabinet, it is characterized in that: the bottom at cabinet is provided with air admission hole, and described air admission hole is connected with cable trough.
Aforesaid forced ventilation outdoor cabinet is characterized in that: described ventilating fan is arranged at the top in the cabinet, is provided with air exhaust passage on the top cover of rack.
The beneficial effect that the utility model reached:
Forced ventilation outdoor cabinet of the present utility model, based on cable trough air flows heat transfer technology, utilize the air in the cable trough of outdoor cabinet working site below to participate in heat radiation, soon the air in the cable trough imports outdoor cabinet inside from the air admission hole of outdoor cabinet bottom, be replenishing of conventional intake method, guarantee the normal operation of cabinet inner electronic equipment.
Description of drawings
Fig. 1 is the structural representation of outdoor cabinet of the present utility model.
Embodiment
Outdoor cabinet of the present invention can keep the temperature in the cabinet to be in the scope of requirement by forced ventilation effectively, guarantees the normal operation of cabinet inner electronic equipment.
Cable trough is to place cable, in depth down, extends in all direction, and the ground face closure is only at rack installation position opening.Air in the cable trough since be in for a long time underground, so its characteristics such as to have temperature affected by environment little, and variations in temperature is little and stable, and humidity is low, and dust is few.Forced ventilation outdoor cabinet of the present utility model comprises cabinet 2, and cabinet is equipped with electronic equipment 3, cabinet 2 ventilating fan 4 is set, ventilating fan 4 is arranged at the top in the cabinet, is provided with air exhaust passage on the top cover 5 of rack, bottom at cabinet is provided with air admission hole, and air admission hole is connected with cable trough 1., and discharge in the air inspiration cabinet in the cable trough by ventilating fan, the high temperature air in the cabinet is in time discharged from cabinet top.
It is low that Air Flow heat exchange mode of the present utility model has a cost, and good heat dissipation effect is simple and easy to do, other equipment are not produced the advantages such as interference.
Claims (2)
1. the forced ventilation outdoor cabinet based on the heat exchange of cable trough air flows comprises cabinet, and ventilating fan is set in cabinet, and it is characterized in that: the bottom at cabinet is provided with air admission hole, and described air admission hole is connected with cable trough.
2. the forced ventilation outdoor cabinet based on the heat exchange of cable trough air flows according to claim 1 is characterized in that: described ventilating fan is arranged at the top in the cabinet, is provided with air exhaust passage on the top cover of rack.
