Abstract
The present invention discloses a low-voltage switchgear. The switchgear comprises a cabinet, a top radiation fan and venting holes. A left radiation fan is arranged on a left side surface of the cabinet close to the bottom, and a right radiation fan is arranged on the right side surface of the cabinet close to the bottom. Both the left radiation fan and the right radiation fan blow air towards the interior of the cabinet. Compared with the prior art, the beneficial effects of the invention are that, the left radiation fan and the right radiation fan of the low-voltage switchgear blow cold air from the external to the interior of the cabinet simultaneously, generating a high-pressure air flow at the bottom in the cabinet, and the top radiation fan exhausts air to the external, generating a negative pressure on the top, so that the high-pressure air flow at the bottom is exhausted from the top with heat, thereby providing good radiation effects for the bottom and the top of the interior of the cabinet.
Description
Technical field
The present invention relates to electric power system auxiliary facility field, relate in particular to a kind of low-tension switch cabinet.
Background technology
When low-tension switch cabinet 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 above+35 ℃ in 24h.Existing low-tension switch cabinet is provided with radiator fan at the top usually, cooperates trailing flank and the louvre on the left and right sides of cabinet to carry out circulation of air, takes away the heat in the cabinet, and still, the radiating effect of bottom of cabinet bulk is usually all poor.
Summary of the invention
The problems referred to above that the present invention need to solve are for above-mentioned the deficiencies in the prior art, and provide a kind of thermal diffusivity good low-tension switch cabinet.
For solving the problems of the technologies described above, the technical solution used in the present invention 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 all are to dry in cabinet.
Described ventilation hole is located at respectively behind the leading flank, trailing flank, left surface of cabinet right flank near the position at top.
Compared with prior art, the invention has the beneficial effects as follows: this low-tension switch cabinet, left side radiator fan and right side radiator fan are simultaneously with in the air intake cabinet colder in the environment, the cabinet inner bottom part forms pressure-air stream, the outside exhaust of top heat dissipation fan, form negative pressure at the top, the pressure-air stream of bottom will be discharged from the top with heat, and the radiating effect at whole cabinet inner bottom part and top is all very good.
Description of drawings
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 the preferred technical solution of the present invention 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 all are 1 blowings in the cabinet.
Because cold air descends, so the air near bottom of cabinet bulk in the environment around the cabinet 1 is colder comparatively speaking, left side radiator fan 3 and right side radiator fan 4 are with being blown in the cabinet 1 than cold air in the environment, high pressure draught can be formed on the bottom in cabinet, because top heat dissipation fan 2 air draft outside cabinet, form negative pressure at the top, the high pressure draught of bottom is just discharged from the top with heat, thereby so that the radiating effect at cabinet inner bottom part and top is all very good.
Claims (2)
1. low-tension switch cabinet, comprise cabinet (1), top heat dissipation fan (2) and ventilation hole (5), it is characterized in that: 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) all are 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) near the position at top.
