Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to a novel outdoor heat dissipation electrical cabinet. Background Art

[0002] Electrical cabinets are made of steel and are used to protect the normal operation of components. Electrical cabinets are generally made of hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] Outdoor electrical cabinets are often set up in areas around roads and are seriously affected by flying dust on the roads, especially in summer. The power consumption in cities is high, and a large amount of heat is generated when the electrical cabinet itself is working. When the heat inside the electrical cabinet is discharged by a commonly used fan or exhaust motor, the flying dust brought by passing cars on the city road often blocks the heat dissipation exhaust port of the electrical cabinet, resulting in poor heat dissipation effect inside the electrical cabinet. The heat inside the motor cabinet cannot be dissipated in time, and part of the heat is conducted along the outer wall of the incoming cable. The local high temperature of the incoming cable may cause spontaneous combustion. For this reason, a new outdoor heat dissipation electrical cabinet is invented. Summary of the invention

[0016] Preferably, the heat dissipation plate is a hollow structure.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a new outdoor heat dissipation electrical cabinet, which has the following beneficial effects:

[0019] 1. The new outdoor heat dissipation electrical cabinet is provided with an outer filter and an inner filter on both sides of the filter clamp to avoid clogging by impurities in the external air or clogging by impurities accidentally discharged from the output pipe from the main body. The external impurities are isolated from the impurities accidentally discharged from the output pipe. When external impurities clog the outer filter, strong wind from the other side is pressed into the channel between the island wind upper plate and the wind guide lower plate, and at the same time, it gathers wind force together with the hot air discharged from the output pipe from the heat dissipation motor, and impacts the impurities attached to and blocked on the outer filter to fall off from the filter holes. As the heat dissipation motor continues to work, the hot air in the holes continuously impacts the impurities on the outer filter, which has an automatic anti-clogging effect.

[0020] 2. For this new outdoor heat dissipation electrical cabinet, when the heat dissipation motor discharges the heat inside the main body, the heat is discharged from the card slot to the channel between the lower air guide plate and the upper air guide plate. At the same time, the channels on both sides of the upper air guide plate and the lower air guide plate are designed to be narrowed toward the middle to increase the contact area with the external air. When the external air blows into the channel between the upper air guide plate and the lower air guide plate, the air is compressed and enters between the upper air guide plate and the lower air guide plate, and then discharged from the other side, accelerating the heat discharge from the channel.

[0021] 3. For this new outdoor heat dissipation electrical cabinet, when it rains in the hot summer, the rain shield body can collect external rainwater. When the rainy day passes and the sunny day comes, the rainwater inside the rain shield body can delay the high temperature generation of the rain shield body and the top of the body.

[0022] 4. For this new outdoor heat dissipation electrical cabinet, when the incoming cables inside the incoming holes burn due to high temperature in summer, the flame-retardant partitions between the two incoming holes will have a flame-retardant effect on the burning cables. When the cables inside the incoming holes burn spontaneously, the flame-retardant partitions on both sides will come into contact with the fire and isolate the incoming cables inside the other two flame-retardant partitions to provide isolation and protection.

[0023] 5. This new outdoor heat dissipation electrical cabinet is equipped with a shielding plate on the collection trough to prevent external garbage from falling into the collection trough and causing garbage blockage due to the wind. When part of the garbage is blown to the top of the shielding plate by the wind, the garbage will roll to both sides along the arc-shaped slope of the wind.

[0024] 6. For the new outdoor heat dissipation electrical cabinet, when the aqueous solution recovered inside the rain shield body flows into the filter device through the water guide pipe, the aqueous solution sliding down from the filter device slides down along the top of both sides of the lower air guide plate. When the aqueous solution flows on the lower air guide plate, the heat conducted by the squeeze between the outer wall of the incoming cable and the inner wall of the cooling trough is absorbed by the lower air guide plate and is taken away with the downward sliding of the aqueous solution, thereby avoiding the overheating and spontaneous combustion of the incoming cable when working in summer. At the same time, the heat inside the main body is conducted away by the contact between the outer wall of the incoming cable and the high-temperature environment inside the main body.

[0025] 7. For this new outdoor heat dissipation electrical cabinet, when the connection block is squeezed and connected in the docking groove, the rubber strip undergoes elastic deformation. When the connection block is completely connected in the corresponding docking groove, the rubber strip recovers its elastic deformation and is squeezed in the docking groove, thus achieving a secondary fixing effect, thereby preventing the main body from being subjected to severe impact and the main body itself from vibrating and vibrating the shielding plate off from the rain shield.

[0026] 8. The new outdoor heat dissipation electrical cabinet is provided with a brush plate at the bottom outlet of the heat dissipation disk. When the heat of the main body is absorbed by the heat dissipation motor through the heat dissipation disk and then discharged from the main body from the output pipe, the dust and impurity particles inside the main body also flow into the heat dissipation disk with the hot air. At this time, the brush plate will block the dust particles and impurities absorbed. At the same time, as the heat dissipation motor continuously draws wind force upward, the brush plate flashes and shakes the dust attached to the brush plate to automatically shake it off, so as to avoid the blockage of impurities and dust affecting the heat discharge inside the main body.

A small hole in the center of the circle is opened on the top of the water pipe 304, and the heat sink 104 is an internal hollow structure.

[0044] Working principle:

[0045] During use, when the heat dissipation motor 102 discharges the heat inside the main body 1, the heat is discharged from the slot 303 toward the channel between the lower air guide plate 302 and the upper air guide plate 301. At the same time, the channels on both sides of the upper air guide plate 301 and the lower air guide plate 302 are designed to be narrowed toward the middle to increase the contact area with the external air. When external air blows into the channel between the upper air guide plate 301 and the lower air guide plate 302, the air is compressed and enters between the upper air guide plate 301 and the lower air guide plate 302, and then is discharged from the other side of the air, thereby accelerating the discharge of heat from the channel.

[0046] By arranging an outer filter 602 and an inner filter 603 on both sides of the filter clamp 601, it is possible to avoid clogging of impurities in the external air or clogging of impurities accidentally discharged from the output pipe 103 from the inside of the main body 1, and to isolate the external impurities from the impurities accidentally discharged from the inside of the output pipe 103. When external impurities clog the outer filter 602, strong wind from the other side is pressed into the channel between the island wind upper plate 301 and the wind guide lower plate 302, and at the same time, the wind force is gathered together with the hot air discharged from the inside of the output pipe 103 from the heat dissipation motor 102, and the impurities attached to and clogged on the outer filter 602 are impacted and fall off from the filter holes. As the heat dissipation motor 102 continues to work, the hot air in the holes continuously impacts the impurities on the outer filter 602, thereby achieving an automatic anti-clogging effect.

[0047] When it rains in the hot summer, the rain shield body 401 can collect external rainwater. When the rainy day passes and the sunny day comes, the rainwater inside the rain shield body 401 can delay the high temperature generation of the rain shield body 401 and the top of the main body 1.

[0048] When the incoming cables inside the incoming hole 202 burn due to high temperature in summer, the flame retardant partition 203 between the two incoming holes 202 has a flame retardant effect on the burning cables. When the cables inside the incoming hole 202 burn due to spontaneous combustion, the flame retardant partitions 203 on both sides come into contact with the fire and isolate the incoming cables inside the other two flame retardant partitions 203 to provide isolation and protection.

[0049] By providing a shielding plate 501 on the collecting trough 402, it is prevented that external garbage is blown into the collecting trough 402 by the wind and causes garbage blockage. When part of the garbage is blown to the top of the shielding plate 501 by the wind, the garbage will roll to both sides along the arc slope of the wind.

[0050] When the aqueous solution recovered inside the rain shield body 401 flows into the filter device 6 through the water guide pipe 304, the aqueous solution sliding down from the filter device 6 slides down along the top of both sides of the lower air guide plate 302. When the aqueous solution flows on the lower air guide plate 302, the heat squeezed and conducted between the outer wall of the incoming cable and the inner wall of the cooling trough 305 is absorbed by the lower air guide plate 302 and is taken away with the downward sliding of the aqueous solution, thereby preventing the incoming cable from overheating and spontaneous combustion during summer operation. At the same time, the heat inside the main body 1 is conducted away through heat conduction between the outer wall of the incoming cable and the high temperature environment inside the main body 1.

[0051] When the connecting block 502 is squeezed and connected to the docking groove 404, the rubber strip 503 undergoes elastic deformation. When the connecting block 502 is completely connected to the corresponding docking groove 404, the rubber strip 503 restores its elastic deformation and is squeezed on the inside of the docking groove 404, thereby achieving a secondary fixing effect, thereby preventing the main body 1 from being subjected to severe impact and the main body 1 itself from vibrating and causing the shielding plate 501 to fall off from the rain shield 4.

[0052] By providing a brush plate 105 at the bottom outlet of the heat dissipation disk 104, when the heat of the main body 1 is absorbed by the heat dissipation motor 102 through the heat dissipation disk 104 and then discharged from the inside of the main body 1 from the output pipe 103, the dust and impurity particles inside the main body 1 also flow into the inside of the heat dissipation disk 104 along with the hot air. At this time, the brush plate 105 will block the absorbed dust particles and impurities. At the same time, as the heat dissipation motor 102 continuously draws wind force upward, the brush plate 105 flashes and shakes the dust attached to the brush plate 105 to automatically shake it off, thereby preventing the impurities and dust from clogging and affecting the heat discharge from the inside of the main body 1.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
