Furthermore, in the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Along with the rapid development of economy, the dependence degree of production and life on electric power is larger and larger, and stable electric power supply has not only influence the daily life quality of people, but also concerns the development and stability of economy and society. Among the many factors that affect the reliability of electrical devices, heat dissipation is a critical one. As a power cabinet of a plurality of precise equipment carriers, a reasonable heat dissipation mode is particularly important.
More adopts the mode of water-cooling to cool down to the electric power cabinet now, but low temperature water can only flow in a sealed passageway, then cool down to the air in the surrounding environment, but can not the electric component in the electric power cabinet of initiative contact, so the effect of cooling down is limited, if the cooperation fan works, under the air current effect that the fan produced, more dust can get into in the electric power cabinet, so dustproof effect also can reduce.
Therefore, the invention provides a dustproof electric cabinet based on water-cooled cooling, as shown in fig. 1, the electric cabinet comprises a cabinet body 100, an electric cabinet 100A is arranged in the cabinet body 100, a cabinet door is arranged on at least one side of the electric cabinet 100A, the electric cabinet 100A is in a sealed state after the cabinet door is closed, a bearing frame 110 is arranged in the electric cabinet 100A, electric elements are fixed on the bearing frame 110, a cooling mechanism 200 is further arranged in the electric cabinet 100A, as shown in fig. 2, the cooling mechanism 200 comprises a hot-flow box 210 and a cold-flow box 220, the hot-flow box 210 is arranged above the electric cabinet 100A, the cold-flow box 220 is positioned on one side below the hot-flow box 210, the two are fixedly connected into an L-shaped integrated structure, and in combination with fig. 4, the hot-flow box 210 and the cold-flow box 220 are hollow, and the hollow parts are mutually communicated, in addition, a hot-flow inlet 210B is arranged on one side of the hot-flow box 210, which is far from the cold-flow box 220, and an exhaust port 220A is arranged on the same side as the hot-flow inlet 210B.
As is well known, the high temperature gas generated in the power chamber 100A will flow upward, so the high temperature gas will be concentrated around the hot fluid box 210, and if the hot fluid box 210 has the capability of pushing gas, then the high temperature gas around the hot gas box will be pressed into the hot fluid inlet 210B, in order to solve the problem of how to push the high temperature gas in the hot fluid box 210, in the first embodiment, the pushing body 260 is disposed in the hot fluid box 210, the liquid condensation group 250 is disposed above the pushing body 260, and the low temperature water is intermittently input to the far side above the pushing body 260 (i.e. the side where the hot fluid inlet 210B is located).
Further, the pushing body 260 is disposed at a side of the hollow portion of the hot-flow box 210, and the inner side of the pushing body 260 is a flexible layer, once the low-temperature water is inputted, the flexible layer is deformed downward under the action of the water gravity, the protrusions generated by the deformation move along with the water, so that the high-temperature gas in the hot-flow box 210 is pushed to move into the cold-flow box 220 by the moving protrusions, meanwhile, the low-temperature water in the pushing body 260 absorbs the heat of the high-temperature gas, so that the gas entering the cold-flow box 220 is changed into the low-temperature gas, and finally the low-temperature gas is discharged to the bottom of the electric power chamber 100A through the air outlet 220A.
Moreover, because the power chamber 100A is a sealed environment, when the high-temperature gas in the heat flow box 210 is pressed away, a negative pressure difference is generated between the inside of the heat flow box 210 and the outside thereof, the high-temperature gas outside the heat flow box 210 flows into the heat flow box 210 again under the action of the negative pressure, and meanwhile, the low-temperature gas at the bottom flows up under the action of the negative pressure, so that the high-temperature gas at the top is reduced, and the low-temperature gas is directly contacted with the electrical element to achieve the purpose of cooling.
The intermittent water inlet mode can form a protrusion continuously to move in the hot flow box 210, and the water in the propulsion body 260 is discharged at the other end.
Preferably, the pushing body 260 is in an L-shape, so that the pushing body 260 falls to one side of the hollow parts of the hot-flow tank 210 and the cold-flow tank 220, but the extrusion of water is utilized in the cold-flow tank 220 to expand the flexible layer on the inner side, and then the protrusion is formed, and the protrusion moves synchronously in the process of falling under water, so that the low-temperature gas in the cold-flow tank 220 can be pushed to quickly reach the exhaust port 220A and be discharged.
In addition, as shown in fig. 4 and 6, firstly, fig. 6 discloses a specific structure of a liquid condensing group 250, the liquid condensing group 250 is composed of a condensing box 251 and an intermittent water inlet system, the condensing box 251 is disposed above a hot-flow box 210, so as to shorten the distance between low-temperature water flowing into a propulsion body 260 as far as possible, so that the water temperature in the propulsion body 260 is controlled at 6-15 ℃, a liquid outlet pipe 254 is disposed at the bottom of the condensing box 251, in fig. 4, a liquid inlet 210A is disposed on the hot-flow box 210 at the side of a hot-flow inlet 210B, the liquid outlet pipe 254 passes through the liquid inlet 210A to be connected with the far side above the propulsion body 260, the intermittent water inlet system is disposed before the low-temperature water flows into the propulsion body 260, and includes a flow control box 253, as shown in fig. 7, at least one flow control paddle 2531 is rotatably connected in the flow control box 253, preferably two flow control paddles 2531 are disposed in an opposite manner, and a motor is disposed in the axial direction of the flow control paddle 2531 to drive so that the flow control paddle 2531 can rotate in the flow control box 253.
It should be noted that, the flow control blade 2531 needs to be attached to the inner wall of the flow control tank 253, so that the flow control tank 253 is divided into two chambers, if N flow control tanks 253 are provided, N chambers are formed, where N is greater than or equal to 1, then each chamber is subjected to one-time low-temperature water input after passing through the liquid outlet pipe 254, and thus an intermittent water delivery mode is formed by continuous rotation of the flow control blade 2531.
Further, as shown in fig. 2, the cooling mechanism 200 further includes a liquid collection tank 230, the liquid collection tank 230 is disposed below the cold flow tank 220, in fig. 8, an end portion of the propelling body 260 for discharging water is connected to the liquid collection tank 230, thereby discharging water into the liquid collection tank 230, collecting low-temperature water by the liquid collection tank 230, and a return pipe 240 is disposed at one side of the liquid collection tank 230, a negative pressure pump 241 is disposed on the return pipe 240, and low-temperature water in the liquid collection tank 230 is output into the condensation tank 251 under the action of the negative pressure pump 241.
However, the water inlet mode of the condensation tank 251 is not limited to the above mode, and may be directly connected to an external water pipe, but the above mode is more preferable, because it is more environment-friendly, and the temperature of the low-temperature water increases by not more than 5 degrees celsius in the whole flowing process, so the low-temperature water recovered by the liquid collection tank 230 has a cooling function, and as shown in fig. 3, the hot-flow tank 210, the cold-flow tank 220, the liquid collection tank 230 and the return pipe 240 are arranged around the periphery of the carrier 110, so that the periphery of the carrier 110 can be cooled integrally.
In addition, on the basis of setting the return pipe 240, a transition pipe 252 is disposed below the condensation tank 251, in this embodiment, the transition pipe 252 is connected to the upper side of the flow control tank 253, the lower side of the flow control tank 253 is connected to the liquid outlet pipe 254, when in use, as shown in fig. 8, firstly, high temperature gas is concentrated on the periphery of the hot flow tank 210, and the hot flow tank 210 already has high temperature gas therein, the liquid outlet pipe 254 introduces low temperature water into the propulsion body 260, because the principle of realizing intermittent water delivery by the flow control tank 253 in this embodiment has been described, and not described herein, in addition, the hot flow tank 210 and the cold flow tank 220 form a gas flow channel 200A and a liquid flow channel 260A under the separation of the propulsion body 260, the liquid flow channel 260A is located on the outside for the low temperature water to flow, the gas flow channel 200A is located on the inside for the gas to flow (the hot flow tank 210 covers Duan Gonggao temperature gas to flow, the cold flow box 220 covers the section for flowing the low-temperature gas), then the low-temperature water presses down the flexible layer in the liquid flow channel 260A covered by the hot flow box 210 to form a protrusion, and moves along with the low-temperature water along with the inner wall of the air flow channel 200A, the high-temperature gas is pushed to flow in the moving process, meanwhile, the high-temperature gas is cooled to be changed into the low-temperature gas, and flows into the air flow channel 200A covered by the cold flow box 220, then the low-temperature water also flows into the liquid flow channel 260A covered by the cold flow box 220, the aperture of the liquid flow channel 260A of the section is reduced, the low-temperature water enters into the flexible layer to be extruded to expand so as to form the protrusion along with the inner wall of the air flow channel 200A, and then the protrusion synchronously falls along with the low-temperature water, so that the low-temperature gas is rapidly pressed to the exhaust port 220A and discharged to the bottom of the electric power chamber 100A.
Because the power chamber 100A is a sealed environment (the dust entering amount is reduced, the dust-proof effect is achieved), when the high-temperature gas in the heat flow box 210 is pressed away, a negative pressure difference is generated between the inside of the heat flow box 210 and the outside of the heat flow box, the high-temperature gas outside the heat flow box 210 flows into the heat flow box 210 again under the action of the negative pressure, and meanwhile, the low-temperature gas at the bottom flows up under the action of the negative pressure, so that the high-temperature gas at the top is reduced, and the low-temperature gas is directly contacted with the electrical element to achieve the purpose of cooling.
Moreover, the flow direction of the high-temperature gas is changed under the action of the low-temperature water forming protrusion, so that the high-temperature gas can move along with the low-temperature water, on one hand, the flow speed of the high-temperature gas in the power chamber 100A is improved, and on the other hand, the low-temperature state of the high-temperature gas is maintained by the low-temperature water, and the situation that the low-temperature gas cannot be discharged from the exhaust port 220A due to the long-path flow is avoided.
Also, the bottom end of the pushing body 260 is required to seal the bottom of the cold flow tank 220, so as to prevent the low temperature gas from flowing into the liquid collecting tank 230, while the bottom end of the pushing body 260 is connected with the liquid collecting tank 230, so that the low temperature water is discharged into the liquid collecting tank 230, and the opposite side return pipe 240 inputs the water in the liquid collecting tank 230 into the condensing tank 251 as follows:
firstly, the negative pressure pump 241 is in a non-operation state, after the water storage capacity in the condensing box 251 is low to the water storage capacity of all the transition pipes 252, the negative pressure pump 241 operates, the condensing box 251 can have longer time to cool water through the transition of the transition pipes 252, and particularly, the condensing pipes are arranged in the condensing box 251 to cool water, so that the operation times of the negative pressure pump 241 are reduced.
