Description

Switchgear with cooling function

technical field

The utility model relates to the field of electric equipment, in particular to a switch cabinet with a heat dissipation function.

Background technique

The switchgear is a common electrical equipment in the power industry. There are various instruments, switches, electronic module units, etc. in the switchgear. As the switchgear continues to work, the instruments, electronic module units, etc. in the cabinet will A large amount of heat is generated, causing the temperature in the cabinet to rise continuously, and excessive temperature will cause the instrument to fail to work normally. Therefore, cooling and heat dissipation is a problem that needs to be solved in the switch cabinet. At present, there are many switch cabinets with heat dissipation function.

The patent number is 201320193342.0, and the technical solution named dehumidification and cooling switchgear involves a switchgear, including a cabinet body and a circuit part. The cabinet body is provided with a cabinet cavity for electrical components, and the upper and lower parts of the cabinet body are respectively provided with air intake channels. and the air outlet, the air inlet channel is provided with a desiccant, the air outlet is provided with louvers and an exhaust fan, the exhaust fan is connected with a fan motor to drive it to rotate, the cabinet cavity is provided with a heating resistance wire for heating and dehumidification, the heating resistance wire Connect to 220V AC power supply through resistance wire relay. The cooling effect of this structure is not very obvious. Although there is an exhaust fan, because there are many instruments and other equipment in the cabinet, the air blown by the exhaust fan cannot achieve the expected cooling effect by relying on only one exhaust fan.

The patent number is 201220453517.2, and the title is a technical solution for heat dissipation switchgear. It refers to a switchgear, including the switchgear body. The bottom and top of the switchgear body are equipped with cooling holes, and the top is also equipped with a fan. The air inlet of the fan Facing the inside of the switch cabinet, and the air inlet is provided with a helical air inlet pipe. Although the air inlet pipe is spiral, it may not be able to generate a strong air swirl, and because the air inlet pipe itself has a small diameter, it is easy to cause the air to be too slow and the heat dissipation efficiency to be low.

Utility model content

The utility model provides a switch cabinet with a heat dissipation function, which solves the problem that the overall heat dissipation effect of the conventional switch cabinet is not very good and the heat dissipation efficiency is relatively low.

The purpose of this utility model is achieved through the following technical solutions: a switchgear with heat dissipation function, including a switchgear body, the bottom of the switchgear body is provided with a foot for supporting the switchgear body, and the bottom of the switchgear body is provided with a first Blower, the air outlet of the first blower faces the inside of the switch cabinet body, the top of the switch cabinet body is provided with an exhaust fan, the air inlet of the exhaust fan faces the inside of the switch cabinet body, and the two opposite sides of the switch cabinet body are respectively provided with a second Blower and the 3rd blower, the air outlet of the 2nd blower and the 3rd blower are all towards switchgear body interior, the outside of the 1st blower, suction fan, the 2nd blower and the 3rd blower are all provided with rainproof cover.

Compared with the traditional switchgear with heat dissipation function, this solution has a great improvement in structure. The traditional switchgear is nothing more than simply exhausting the heat in the cabinet through the exhaust fan, but this traditional way of cooling The efficiency is very low and the effect cannot be achieved. Therefore, in this plan, blowers and exhaust fans are installed in four positions respectively. The selection of the positions and the types of fans is particular. First, a blower is installed at the bottom of the switch cabinet to introduce the natural cold air outside the cabinet into the cabinet. Since the density of hot air is smaller, It is more effective to discharge from the top, so an exhaust fan is installed on the top of the switch cabinet, so that one in and one out, forming a fast heat dissipation channel, the blower below keeps blowing hot air upwards, and the exhaust fan above does not stop The hot air is drawn out of the switch cabinet efficiently, so that the heat can be dissipated quickly. In addition, a blower is installed on the opposite sides of the switch cabinet to blow the heat staying on the side of the switch cabinet inward, so that the hot air enters the fast heat dissipation channel, so as to realize sufficient heat dissipation in the cabinet.

Further, the first blower and the suction fan are respectively located at the bottom and the center of the top of the switch cabinet body. The air drawn or blown out by the exhaust fan and the blower has a certain range. When the blower and the exhaust fan are located in the center, it can ensure that as much hot air in the cabinet as possible can be taken away.

Further, the second blower and the third blower are located at the same level, and are located at 1/2 of the side height of the switchgear body 1 . Since there is a blower at the bottom and an exhaust fan at the top, the farther the distance from the blower or exhaust fan is, the weaker the wind force is, that is, the wind force at the half-waist of the switch cabinet is relatively weak. At this time, the hot air is likely to flow to the switch cabinet The side is gathered, so the second blower and the third blower are set at 1/2 of the side height of the switchgear body 1, and the hot air at this level is blown inward to facilitate the heat dissipation channel formed by the first blower and the exhaust fan Take away the hot air in time.

Further, the air outlet direction of the second blower is on the same level as the air outlet direction of the third blower. At this time, the hot air at this level can be convected to facilitate the rapid dissipation of heat.

Further, the air outlet directions of the second blower and the third blower are obliquely upward, and the air outlet direction of the second blower just passes through the inner corner formed by the top of the switchgear body and the side where the third blower is located. The air outlet direction of the three blowers just passes through the inner corner formed by the top of the switchgear body and the side where the second blower is located. Due to the limited range of influence of the exhaust fan, there is a dead angle at the intersection of the top and the side of the switchgear, where the hot air is likely to gather and cannot be dissipated in time. After setting the air outlet direction of the second blower and the third blower, the dead angle can be The hot air inside is blown away, and then cooperates with the exhaust fan to take away the heat of this part.

Further, the top of the switchgear body is provided with several cooling holes. The heat dissipation holes can play the role of auxiliary heat dissipation, and part of the heat can be dissipated directly from the heat dissipation holes under the action of the blower.

The utility model has the following beneficial effects: the utility model sets the exhaust fan on the top of the switch cabinet, and sets the blower on the bottom and the side respectively, so as to form a fast heat dissipation channel, and the heat on the side of the switch cabinet is also discharged in time, thereby ensuring The instruments and electronic module units in the switchgear work normally.
