Description

Technical Field

[0001] The present invention belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet device. Background Art

[0002] Distribution cabinets (boxes) are classified as power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final stage of the power distribution system. A distribution cabinet is a general term for motor control centers (MCCs). Distribution cabinets are used in applications with relatively dispersed loads and a small number of circuits, while MCCs are used in applications with concentrated loads and a large number of circuits. They distribute power from a circuit in the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the loads.

[0003] Due to the large number of electronic components in a power distribution cabinet, excessive temperatures can easily occur, causing damage to the components. Existing methods typically dissipate heat within the cabinet by introducing outside air. However, this cooling process also introduces dust into the cabinet, which can affect the normal operation of the electronic components. Therefore, finding a way to dissipate heat within the cabinet without introducing dust is a challenge. Summary of the Invention

[0004] In order to solve the problem in the prior art of how to dissipate heat in a power distribution cabinet without introducing dust, the present invention provides a power distribution cabinet device.

[0005] The technical solution adopted in the present invention is as follows:

[0006] A power distribution cabinet device comprises a cabinet body, wherein each corner corresponding to two diagonal lines of the cabinet body is provided with an air outlet, and the air outlet is connected to a cold air supply system;

[0007] The cold air supply system includes a shell arranged around the outer side wall of the cabinet, the gap between the shell and the cabinet forms an accommodating cavity, and a refrigeration mechanism and a coolant are arranged in the accommodating cavity;

[0008] A gas extraction mechanism is provided in the accommodating chamber near each of the air vents, and each of the gas extraction mechanisms is connected to each of the air vents respectively;

[0009] The gas extraction mechanism includes a hollow column arranged in the accommodating chamber, a piston is slidably arranged in the hollow column, and a gas inlet and outlet connected to the air port and a liquid inlet and outlet connected to the accommodating chamber are respectively provided at both ends of the hollow column. The side of the hollow column where the liquid inlet and outlet are provided is connected to a driving mechanism for driving the piston to move.

[0010] After adopting this technical solution, the present invention uses a gas extraction mechanism set in the coolant to suck the gas in the cabinet into the hollow column or discharge the cooled cold air in the hollow column into the cabinet, so that the air flows in the cabinet and the hollow column, realizing self-circulation, achieving the cooling effect without introducing outside air, and effectively preventing dust from entering the distribution cabinet;

[0011] The present invention arranges air vents at the corners corresponding to the two diagonal lines in the power distribution cabinet, so that the cold air forms a three-dimensional interweaving in the cabinet, thereby improving the distribution effect of the cold air in the cabinet. At the same time, it also facilitates the hot air from various places to be sucked into the hollow column for cooling, thereby improving the heat dissipation efficiency.

[0012] At the same time, the coolant in the present invention can also directly exchange heat with the cabinet, thereby further improving the cooling effect and achieving the cooling effect of air cooling and water cooling.

[0013] At the same time, one side of the piston in the present invention is connected to the accommodating chamber, and the other side is connected to the distribution cabinet. When the piston moves, it can not only inhale or exhaust air, but also inhale or discharge liquid, thereby driving the flow of coolant, and can make the liquid around the refrigeration mechanism quickly exchange with the liquid after heat exchange and temperature rise, thereby improving the refrigeration effect of the coolant, thereby improving the heat dissipation effect.

[0014] Preferably, there are four air outlets in total, with every two air outlets located on a diagonal line, and each air outlet is arranged toward another air outlet located on the same diagonal line.

[0015] Preferably, two air outlets located on a diagonal line take in or out air at the same time, and the air outlets on the two diagonals take in and out air respectively. The air outlets for taking in air and the air outlets for exhausting air alternate according to the reciprocating motion of the piston, and the air intake volume of each air outlet is equal to the air exhaust volume.

[0016] After adopting this technical solution, the two air vents located on a diagonal line take in or out air at the same time, and each of the air vents is set towards the other air vent located on the same diagonal line. When the two air vents discharge air at the same time, the air flows collide and diffuse outward, thereby improving the dispersion effect of the cold air and allowing the internal air to reach various parts of the distribution cabinet. Moreover, the air vents on one diagonal line discharge air, and the air vents on the other line inhale air, which can not only maintain the air pressure balance in the distribution cabinet, but also assist in the outward dispersion of the cold air after collision, further improving the dispersion effect of the cold air.

[0017] Preferably, the hollow column and the contact points between the cabinet and the accommodating cavity are all made of heat-conductive materials.

[0018] After adopting this technical solution, the contact points between the hollow column and the cabinet and the accommodating cavity are all made of heat-conductive materials, which facilitates heat exchange between the cabinet and the hollow column and the coolant.

[0019] Preferably, the hollow column is provided with several liquid inlets and outlets in a circular ring around the circumference, and the hollow column is provided with a gas inlet and outlet, the gas inlet and outlet are connected to a connecting pipe, the connecting pipe is connected to the air outlet, and a screen is provided at the air outlet for increasing the gas scattering area.

[0020] With this technical solution, the hollow column is provided with several liquid inlets and outlets around its circumference, allowing liquid to enter or exit from all directions, further improving the fluidity of the liquid. The screen disperses the gas discharged from the hollow column, increasing the gas distribution area.

[0021] Preferably, the refrigeration mechanism is an electric refrigeration plate, the coolant is water, a temperature sensor is also provided in the accommodating cavity, the electric refrigeration plate and the temperature sensor are both electrically connected to a control system, and the control system is also electrically connected to a control screen provided on the surface of the shell.

[0022] After adopting this technical solution, the required coolant temperature can be set through the control panel. The electric refrigeration plate and temperature sensor work together to make the coolant reach the required problem, realizing intelligent adjustment of the cooling effect, so that the heat dissipation intensity can be controlled as needed according to different seasons, different time periods or different heat generation.

[0023] Preferably, each of the gas exhaust mechanisms is arranged on the side surfaces adjacent to the cabinet door, the accommodating cavity on the adjacent sides of the cabinet door extends to the opposite side of the cabinet door to form a U-shaped structure, and the refrigeration mechanism is arranged in the middle of the opposite side of the cabinet door.

[0024] After adopting this technical solution, the accommodating cavity forms a U-shaped structure to wrap the outer wall of the cabinet, thereby improving the water cooling effect.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. The present invention uses a gas extraction mechanism provided in the coolant to draw the gas in the cabinet into the hollow column or discharge the cooled cold air in the hollow column into the cabinet, thereby allowing the air to flow in the cabinet and the hollow column, realizing self-circulation, achieving the cooling effect without introducing outside air, and effectively preventing dust from entering the distribution cabinet.

[0027] 2. The coolant in the present invention can also directly exchange heat with the cabinet, thereby further improving the cooling effect and achieving the cooling effect of air cooling and water cooling.

[0028] 3. The present invention sets air vents at the corners corresponding to the two diagonal lines in the distribution cabinet, so that the cold air forms a three-dimensional interweaving in the cabinet, which improves the distribution effect of the cold air in the cabinet. At the same time, it also makes it easier for hot air from all places to be sucked into the hollow column for cooling, thereby improving the heat dissipation efficiency.

[0029] 4. In the present invention, one side of the piston is connected to the accommodating chamber, and the other side is connected to the inside of the power distribution cabinet. When the piston moves, it can not only inhale or exhaust air, but also inhale or discharge liquid, thereby driving the flow of the coolant. The liquid around the refrigeration mechanism can be quickly exchanged with the liquid that has been heated by heat exchange, thereby improving the refrigeration effect of the coolant and thus improving the heat dissipation effect.

[0036] like Figure 1-3 As shown, a power distribution cabinet device includes a cabinet body 1, wherein an air vent 3 is provided at each corner corresponding to two diagonal lines of the cabinet body 1, and the air vent 3 is connected to a cold air supply system;

[0037] The cold air supply system includes a housing 2 arranged around the outer side wall of the cabinet 1. The gap between the housing 2 and the cabinet 1 forms a receiving cavity. A refrigeration mechanism and a coolant are provided in the receiving cavity. In this embodiment, the refrigeration mechanism is an electric refrigeration plate, and the coolant is water. The electric refrigeration plate can cool the coolant to a desired temperature.

[0038] A gas extraction mechanism is provided in the accommodating chamber near each of the air vents 3, and each of the gas extraction mechanisms is connected to each of the air vents 3;

[0039] The gas extraction mechanism includes a hollow column 4 arranged in the accommodating chamber, a piston 5 is slidably arranged in the hollow column 4, and a gas inlet and outlet 8 connected to the air port 3 and a liquid inlet and outlet 7 connected to the accommodating chamber are respectively provided at both ends of the hollow column 4. The side of the hollow column 4 where the liquid inlet and outlet 7 is provided is connected to a driving mechanism 6 for driving the piston 5 to move. In this embodiment, the driving mechanism 6 is an electric telescopic column, which drives the piston to move up and down in the hollow column 4 through the electric telescopic column, thereby driving gas and liquid into or out of the hollow column 4.

[0040] In this embodiment, a gas extraction and exhaust mechanism is provided in the cooling liquid to draw the gas in the cabinet into the hollow column 4 or discharge the cooled cold air in the hollow column 4 into the cabinet 1, so that the air flows in the cabinet 1 and the hollow column 4, realizing self-circulation, achieving the cooling effect without introducing outside air, and effectively preventing dust from entering the cabinet 1; air outlets 3 are provided at the corners corresponding to the two diagonal lines in the cabinet 1, so that the cold air forms a three-dimensional interweaving in the cabinet 1, thereby improving the distribution effect of the cold air in the cabinet 1, and also facilitating the hot air from various places to be sucked into the hollow column 4 for cooling, thereby improving the heat dissipation efficiency. At the same time, since the shell 2 and the cabinet 1 jointly form a accommodating cavity, the cooling liquid can also directly exchange heat with the cabinet 1, thereby further improving the cooling effect, and achieving the cooling effect of air cooling and water cooling combined. When one side of the piston 5 is connected to the accommodating chamber and the other side is connected to the cabinet 1, when the piston 5 moves, it can not only inhale or exhaust air, but also inhale or discharge liquid, thereby driving the flow of the coolant, and can make the liquid around the refrigeration mechanism quickly exchange with the liquid that has been heated by heat exchange, thereby improving the refrigeration effect of the coolant and thus improving the heat dissipation effect.

[0041] In other embodiments, a water-absorbing pad can be provided in the air outlet 3 (other water-absorbing components can also be provided in other embodiments, as long as the water content in the gas can be reduced), so that the exhausted air can only be discharged after absorbing moisture through the water-absorbing pad, thereby reducing the water content in the circulating gas and avoiding affecting the normal operation of the equipment in the distribution cabinet.

[0042] In other embodiments, a total of four air vents 3 are provided. In this embodiment, two air vents 3 are provided on the side of the top surface of the cabinet body 1 away from the cabinet door, and two air vents 3 are provided on the side of the bottom surface of the cabinet body 1 close to the cabinet door. Each two air vents 3 are located on a diagonal line, and each of the air vents 3 is arranged toward another air vent 3 located on the same diagonal line. The two air vents 3 located on a diagonal line take in or out air at the same time, and the air vents 3 on the two diagonals take in and out air respectively. The air vents 3 for taking in air and the air vents 3 for outgoing air are alternated according to the reciprocating motion of the piston 5. The air intake volume of each air vent 3 is equal to the air output volume. The two air vents 3 located on a diagonal line take in or out air at the same time, and each of the air vents 3 is set toward the other air vent 3 located on the same diagonal line. When the two air vents 3 discharge air at the same time, the air flows collide and diffuse outward, thereby improving the dispersion effect of the cold air and allowing the internal air to reach various parts of the cabinet 1. Moreover, the air vents on one diagonal line discharge air, and the air vents on the other line inhale air, which can not only maintain the air pressure balance in the cabinet 1, but also assist in the outward dispersion of the cold air after the collision, further improving the dispersion effect of the cold air.

[0043] In other embodiments, the contact surfaces of the hollow column 4 and the cabinet 1 with the accommodating cavity are all made of heat-conductive materials. The contact surfaces of the hollow column 4 and the cabinet 1 with the accommodating cavity are all made of stainless steel, which has good heat conductivity and will not rust.

[0044] In other embodiments, Figure 3 As shown, the hollow column 4 is provided with several liquid inlets and outlets 7 arranged in a circular pattern around its circumference. A gas inlet and outlet 8 is also provided on the hollow column 4. This gas inlet and outlet 8 is connected to a connecting pipe, which is connected to the air outlet 3. The air outlet 3 is provided with a screen to increase the gas scattering area. The circular pattern of liquid inlets and outlets 7 on the hollow column 4 allows liquid to enter or exit from all directions, further improving liquid fluidity. The screen disperses the gas discharged from the hollow column 4, increasing the gas distribution area and thereby improving heat dissipation efficiency.

[0045] In other embodiments, a temperature sensor is further provided within the accommodating cavity, and the electric refrigeration fins and the temperature sensor are both electrically connected to a control system, which is further electrically connected to a control panel provided on the surface of the housing 2. The desired coolant temperature can be set via the control panel, and the electric refrigeration fins and the temperature sensor cooperate to ensure that the coolant reaches the desired temperature, thereby achieving intelligent regulation of the cooling effect. This allows for on-demand control of the heat dissipation intensity according to different seasons, time periods, or heat output.

[0046] In this embodiment, if Figure 2 As shown, each of the gas extraction mechanisms is disposed on the side surfaces adjacent to the cabinet door of the cabinet 1. The accommodating cavity on both sides of the cabinet door of the cabinet 1 extends to the opposite side of the cabinet door of the cabinet 1, forming a U-shaped structure. The refrigeration mechanism is disposed in the middle of the opposite side of the cabinet door of the cabinet 1. The U-shaped structure of the accommodating cavity wraps around the outer wall of the cabinet 1, thereby improving the water cooling effect.

[0047] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
