Description

Technical Field

[0001] The invention relates to an electrical device, in particular to a heat dissipation switch cabinet and a heat dissipation method thereof. Background Art

[0002] Switchgear is an electrical equipment, whose main function is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. The external line of the switchgear first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protection devices, such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc.

[0003] The heat generated by the electrical components installed in the switch cabinet needs to be discharged continuously to ensure the normal operation of the electrical components. Existing switch cabinets mostly use open heat dissipation holes to cool the equipment inside the switch cabinet. The open heat dissipation structure makes it easy for mosquitoes outside the cabinet to enter the cabinet through these heat dissipation holes, which will affect the service life of the cabinet; in addition, dust outside the cabinet can also easily enter the cabinet through the heat dissipation holes, which will also cause damage to the cabinet; furthermore, on rainy days, rain or humid air can easily enter the cabinet through the heat dissipation holes; and the open heat dissipation holes will also affect the operation of the dehumidification and drying device.

[0044] The setting of the first sliding pressure block 37 and the second sliding pressure block 38 can press the absorbent cotton abutting the side end of the film 36, and lock the absorbent cotton at this point while squeezing out the moisture in the absorbent cotton, so that the absorbent cotton at the lower end is squeezed by the first pressure block 34 and the second pressure block 35, preventing the water in the absorbent cotton from flowing back, so that the water can drip into the collection and drainage box 24 better, thereby discharging the condensed water out of the device.

[0045] A sliding mechanism is provided at the rear end of the inner wall of the shell 1, and a sliding fan box 11 is provided on the sliding mechanism. The sliding mechanism consists of a transverse guide rail 12 and a longitudinal guide rail. The transverse guide rail 12 is fixed to the inner wall of the shell 1, and a first linear motor is provided on the longitudinal guide rail.

The front of the housing 1 is hinged with a cover plate 3, and the inner top wall of the housing 1 is provided with an observation lamp post.

[0047] The working principle of a heat dissipation switch cabinet proposed in this embodiment is as follows:

[0048] First, the motor and components of the device are powered on, then the telescopic air pipe 4 is connected to an additional air supply source, and the water discharge port 27 is connected to a drain pipe, and then the various components and mechanisms of the device are installed, and then the components in the switch cabinet are powered on, so that the components in the switch cabinet can operate normally. The setting of the moisture-proof pad 15 can better dry the working environment and prevent the components in the switch cabinet from being damp and affecting the normal operation of the device. The setting of the inclined plate on the moisture-proof window 2 can make the condensed water vapor droplets fall on the outside of the shell 1, thereby preventing the inside of the switch cabinet from being damp.

[0049] Then, the air supply mechanism 14 in the isolation chamber is started. The air supply mechanism 14 cooperates with the ventilation mounting slot 10 to form air convection, thereby improving the temperature control effect. By setting the cooling conduction mechanism 8 and the heating conduction mechanism 9 in the isolation chamber, it is possible to better cope with the influence of changes in ambient temperature on the operation of the internal working components of the switch cabinet, thereby improving the versatility of the switch cabinet. The operation of the upper and lower air supply mechanisms 14 in the isolation chamber can achieve the effect of speeding up air exchange.

[0050] Then the airflow passes through the dust-proof air inlet cloth cover at the front end of the air supply mechanism 14. The setting of the dust-proof air inlet cloth cover can better block dust and prevent dust from entering the interior of the shell 1 through the air supply mechanism 14. Through the setting of the oscillating dust removal mechanism 18, the sliding block 42 can be driven to slide when the air supply mechanism 14 starts and stops and the power operation changes, and cooperate with the oscillation spring 23 to drive the sliding block 42 to oscillate back and forth, so that the dust-proof air inlet cloth cover is pushed and collided back and forth, thereby oscillating to remove dust on the dust-proof air inlet cloth cover, and preventing the dust-proof air inlet cloth cover from being blocked and affecting the air supply operation of the air supply mechanism 14.

[0051] When the air humidity is high, the refrigeration conduction mechanism 8 condenses the water vapor enriched in the air into droplets through the low-temperature condensation effect of the first heat-conducting plate 28 and the first heat-conducting copper tube 29, and attaches them to the first heat-conducting plates 28 distributed at equal intervals. At this time, the linear motor sliding box 30 drives the water collecting connecting rod 25 to slide horizontally on the collecting and draining box 24, and the sliding water collecting connecting rod 25 drives the cleaning chuck to slide on the first heat-conducting plate 28. The condensed water cleaning and discharge mechanism can absorb the condensed water on the first heat-conducting plate 28 to the absorbent cotton through the setting of the bonding plate 32 and the adsorption and deliquidation cotton 33. During the sliding process of the water collecting connecting rod 25, the absorbent cotton at the end of the water collecting connecting rod 25 is The first pressing block 34 and the second pressing block 35 are squeezed, and at the same time, the second sliding pressing block 38 is pushed up by the second pressing block 35, and the rising second sliding pressing block 38 pushes the first sliding pressing block 37 through the inclined block that is in contact with the film 36, and the first sliding pressing blocks 37 on both sides move relatively to press the absorbent cotton on the inner side of the abutting film 36, and while squeezing and removing the moisture in the absorbent cotton here, the absorbent cotton here is locked, so that the bottom of the absorbent cotton is squeezed by the first pressing block 34 and the second pressing block 35, and the condensed water in the absorbent cotton is prevented from flowing back, so that the condensed water can be better dripped into the collection and drainage box 24, thereby discharging the condensed water. The condensed water squeezed out or dripped due to gravity enters the drainage box 24 and is discharged from the device through the drain pipe connected to the water discharge port 27.
