Abstract
The utility model discloses a low-pressure switch cabinet. The low-pressure switch cabinet comprises a cabinet body, a top heat dissipation fan and air vents, wherein a position, which is close to the bottom, at the left side surface of the cabinet body is provided with a left-side heat dissipation fan; a position, which is close to the bottom, at the right side surface of the cabinet body is provided with a right-side heat dissipation fan; and the left-side heat dissipation fan and the right-side heat dissipation fan both low air into the cabinet. Compared to the prior art, the low-pressure switch cabinet has the following advantages: the left-side heat dissipation fan and the right-side heat dissipation fan of the low-pressure switch cabinet simultaneously absorb relatively cold air in the environment into the cabinet body so that a high pressure airflow is formed at the bottom inside the cabinet, the top heat dissipation fan discharges air outwards so that a negative pressure is formed at the top, and then the high pressure airflow at the bottom is discharged with heat from the top. The heat dissipation effects of the bottom and the top of the entire cabinet body are both quite excellent.
Description
Technical field
The utility model relates to electric power system auxiliary facility field, relates in particular to a kind of low-tension switch cabinet.
Background technology
When low-tension switch cabinet is used, higher to the requirement of temperature, ambient air temperature must not surpass+40 ℃, be not less than-5 ℃, and its mean temperature must not be over+35 ℃ in 24h.Existing low-tension switch cabinet is provided with radiator fan at top usually, coordinates trailing flank and the louvre on left and right sides of cabinet to carry out circulation of air, takes away the heat in cabinet, and still, the radiating effect of bottom of cabinet bulk is usually all poor.
The utility model content
The problems referred to above that the utility model need to solve are for above-mentioned the deficiencies in the prior art, and the low-tension switch cabinet that a kind of thermal diffusivity is good is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of low-tension switch cabinet, comprise cabinet, top heat dissipation fan and ventilation hole, be provided with the left side radiator fan at the left surface of cabinet near the position of bottom, be provided with the right side radiator fan at the right flank of cabinet near the position of bottom, and left side radiator fan and right side radiator fan are all to dry in cabinet.
Described ventilation hole is located at respectively after the leading flank, trailing flank, left surface of cabinet right flank near the position at top.
Compared with prior art, the beneficial effects of the utility model are: this low-tension switch cabinet, left side radiator fan and right side radiator fan are simultaneously by air intake cabinet colder in environment, the cabinet inner bottom part forms pressure-air stream, the outside exhaust of top heat dissipation fan, form negative pressure at top, the pressure-air stream of bottom will be discharged from top with heat, and the radiating effect at whole cabinet inner bottom part and top is all very good.
The accompanying drawing explanation
Fig. 1 is the structural representation of low-tension switch cabinet;
Wherein, 1, cabinet, 2, the top heat dissipation fan, 3, the left side radiator fan, 4, the right side radiator fan, 5, ventilation hole.
Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of low-tension switch cabinet, comprise cabinet 1, top heat dissipation fan (2) and ventilation hole (5), be provided with left side radiator fan 3 at the left surface of cabinet 1 near the position of bottom, be provided with right side radiator fan 4 at the right flank of cabinet 1 near the position of bottom, and left side radiator fan 3 and right side radiator fan 4 are all to 1 blowing in cabinet.
Because cold air descends, so the air near bottom of cabinet bulk in the environment around cabinet 1 is colder comparatively speaking, left side radiator fan 3 and right side radiator fan 4 are by being blown in cabinet 1 than cold air in environment, high pressure draught can be formed on the bottom in cabinet, due to top heat dissipation fan 2 air draft outside cabinet, form negative pressure at top, the high pressure draught of bottom is just discharged from top with heat, thereby makes the radiating effect at cabinet inner bottom part and top all very good.
Claims (2)
1. a low-tension switch cabinet, comprise cabinet (1), top heat dissipation fan (2) and ventilation hole (5), it is characterized in that: at the left surface of cabinet (1), near the position of bottom, be provided with left side radiator fan (3), be provided with right side radiator fan (4) at the right flank of cabinet (1) near the position of bottom, and left side radiator fan (3) and right side radiator fan (4) are all to dry in cabinet.
2. low-tension switch cabinet according to claim 1 is characterized in that: described ventilation hole (5) is located at respectively leading flank, trailing flank, left surface and the right flank of cabinet (1) position near top.
