Description

Technical Field

[0001] This utility model belongs to the technical field of highway machine rooms, and particularly relates to an energy-saving cooling device for highway machine rooms. Background Art

[0002] With the rapid development of highway informatization construction, highway machine rooms, as key facilities to support highway operation and management, their stable operation is crucial for ensuring traffic flow and safety. However, since a large number of electrical components are concentrated inside highway machine rooms, these electrical components generate a large amount of heat during operation. If the heat dissipation is improper, it will cause the temperature of the machine room to rise, affecting the performance and lifespan of the electrical components, and even potentially triggering safety accidents such as fires.

[0003] Traditional machine room cooling methods mostly use air conditioning for refrigeration, but this method not only has high energy consumption, but also the refrigeration effect is often not satisfactory. In addition, long-term use of air conditioning may also lead to humidity imbalance in the machine room, further exacerbating the aging and damage of electrical components. Therefore, how to effectively reduce the temperature of highway machine rooms, improve the heat dissipation efficiency, and at the same time reduce energy consumption and costs has become an urgent problem to be solved currently.

[0004] In recent years, liquid cooling technology has been widely used in fields such as data centers due to its high efficiency and energy-saving characteristics. By opening cavities on the machine room box body and then allowing cooling water to flow through the cavities, the heat generated by the machine room box body can be taken away, achieving the effect of rapid cooling.

[0005] However, although waterproof and anti-corrosion measures are taken in the early stage when the cooling water directly flows on the machine room box body, under long-term cooling and water flow scouring, the service life of these measures becomes worse and worse, resulting in the phenomenon of damage to the machine room box body.

[0006] Secondly, when the cooling water directly flows on the machine room box body and then is cooled by the air-cooling method and reused, although it can achieve the effect of saving water resources, the cooling effect of the cooling water by the air-cooling method is not good, resulting in the deteriorating effect of the cooling water and further causing the deteriorating cooling effect of the machine room.

[0007] Therefore, we have proposed an energy-saving cooling device for highway machine rooms, which can improve the cooling effect of the cooling water and enable it to be reused again. It can not only improve the cooling effect of the machine room box body, but also achieve the effect of saving water resources. Content of the Utility Model

[0008] The purpose of this utility model is to provide an energy-saving cooling device for highway machine rooms, which can improve the cooling effect of the cooling water and enable it to be reused again. It can not only improve the cooling effect of the machine room box body, but also achieve the effect of saving water resources.

[0009] The technical solution adopted by this utility model is specifically as follows:

[0010] An energy-saving cooling device for a highway machine room includes a machine room box body. A rectangular cavity is opened on the machine room box body. A serpentine water guide pipe is arranged inside the rectangular cavity. A first box body is arranged on the top of the machine room box body. The water inlet and outlet of the serpentine water guide pipe are both arranged on the first box body, and water pumps are arranged at both the water inlet and outlet of the serpentine water guide pipe.

[0011] A honeycomb water flow disperser is arranged inside the first box body. A protective housing communicated with it is arranged on the top of the first box body. A rotating assembly is arranged inside the protective housing. A fan blade is arranged on the rotating assembly. A gas guide pipe located inside the rectangular cavity is arranged at the bottom of the protective housing.

[0012] Furthermore, heat-absorbing fins are arranged inside the rectangular cavity, and the heat-absorbing fins are matched with the serpentine water guide pipe.

[0013] Furthermore, a heat-absorbing surface is arranged on the serpentine water guide pipe.

[0014] Furthermore, the honeycomb water flow disperser is composed of criss-cross heat-absorbing pipes.

[0015] Furthermore, ventilation holes are opened on the first box body and the machine room box body.

[0016] Furthermore, the rotating assembly includes a bracket arranged on the inner wall of the protective housing. A motor is arranged on the bracket, and the output end of the motor is connected to the fan blade.

[0017] The technical effects achieved by this utility model are as follows:

[0018] 1. When the electrical components inside the machine room box body are working, a large amount of heat will be generated. These heats will enter the rectangular cavity. The heat is absorbed by the serpentine water guide pipe, resulting in the serpentine water guide pipe having a high temperature. At the same time, the water pump starts. The water pump makes the cooling water enter through the water inlet of the serpentine water guide pipe. When the water flows inside the serpentine water guide pipe, it will absorb the heat on the serpentine water guide pipe, thereby performing heat exchange and achieving the heat dissipation effect of the machine room box body. Because the serpentine water guide pipe is set, the heat-absorbing area can be increased, which can not only improve the heat exchange effect and further increase the heat dissipation area, but also prevent the cooling water from directly contacting the machine room box body, avoiding corrosion and improving the service life of the machine room box body.

[0019] 2. The rotating assembly drives the fan blade to rotate, thereby providing suction to discharge the heat inside the rectangular cavity through the gas guide pipe, thereby performing secondary heat dissipation.

[0020] 3. When the water pump allows the cooling water to enter through the water inlet of the serpentine water conduit, as the water flows inside the serpentine water conduit and absorbs the heat on the serpentine water conduit, the water that has absorbed heat enters the interior of the first box body from the water outlet of the serpentine water conduit. Then, the water flow drops onto the honeycomb water flow disperser due to gravity. When the water impacts the honeycomb water flow disperser, the water flow forms a dispersed form. At this time, since the rotating assembly drives the fan blades, the air flows. At this time, the contact area between the dispersed water flow and the air increases for rapid heat dissipation, thereby improving the cooling effect of the cooling water so that it can be used again. This can not only improve the temperature reduction effect of the computer room box body but also achieve the effect of saving water resources. Brief Description of the Drawings

[0027] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0028] As Figures 1-4 shown, the technical solution adopted by the present utility model is specifically as follows: An energy-saving temperature reduction device for a highway computer room includes a computer room box body 1. A rectangular cavity 2 is provided on the computer room box body 1. A serpentine water conduit 3 is arranged inside the rectangular cavity 2. And a first box body 4 is provided on the top of the computer room box body 1. Both the water inlet and the water outlet of the serpentine water conduit 3 are arranged on the first box body 4. And water pumps are arranged at both the water inlet and the water outlet of the serpentine water conduit 3;

[0029] Inside the first box body 4, a honeycomb water flow disperser 5 is arranged, and a protective housing 6 communicated with it is arranged at the top of the first box body 4. A rotating assembly is arranged inside the protective housing 6, a fan blade 7 is arranged on the rotating assembly, and an air duct 8 located inside the rectangular cavity 2 is arranged at the bottom of the protective housing 6.

[0030] Its working principle is as follows: First, a large amount of heat is generated when the electrical components inside the machine room box body 1 are working. These heats will enter the inside of the rectangular cavity 2 and are absorbed by the serpentine water pipe 3, resulting in the serpentine water pipe 3 having a very high temperature. At the same time, the water pump starts. The water pump makes the cooling water enter through the water inlet of the serpentine water pipe 3. When the water flows inside the serpentine water pipe 3, it will absorb the heat on the serpentine water pipe 3, thereby performing heat exchange and enabling the machine room box body 1 to achieve the heat dissipation effect. Because the serpentine water pipe 3 is arranged, the heat absorption area can be increased, which can not only improve the heat exchange effect and further increase the heat dissipation area, but also make the cooling water not directly contact the machine room box body 1, so that the corrosion phenomenon will not occur, and the service life of the machine room box body 1 is improved. At the same time, the rotating assembly drives the fan blade 7 to rotate, thereby providing suction force to discharge the heat inside the rectangular cavity 2 from the air duct 8, so as to perform secondary heat dissipation. When the water pump makes the cooling water enter through the water inlet of the serpentine water pipe 3 and the water absorbs the heat on the serpentine water pipe 3 when flowing inside the serpentine water pipe 3, the water that absorbs the heat enters the inside of the first box body 4 from the water outlet of the serpentine water pipe 3, and then the water flow drops onto the honeycomb water flow disperser 5 by gravity. The water impacts on the honeycomb water flow disperser 5 to form a dispersed form of the water flow. At this time, because the rotating assembly drives the fan blade 7, the air flows. At this time, the contact area between the dispersed water flow and the air increases for rapid heat dissipation, thereby improving the cooling effect of the cooling water and enabling it to be used again. This can not only improve the temperature reduction effect of the machine room box body 1, but also achieve the effect of saving water resources.

[0031] Among them, heat absorption fins 9 are arranged inside the rectangular cavity 2. The heat absorption fins 9 are matched with the serpentine water pipe 3. Here, the heat absorption fins 9 are used to introduce the heat inside the machine room box body 1 into the rectangular cavity 2.

[0032] At the same time, a heat absorption surface is arranged on the serpentine water pipe 3. The heat absorption surface material is ceramics, graphite tubes, etc. The heat inside the rectangular cavity 2 can be absorbed through the heat absorption surface.

[0033] The model of the water pump is IQ type pump, a light and small centrifugal pump, with simple structure, light weight, low price, good performance and convenient matching. The pump caliber is 50 - 200 mm, the flow rate is 12.5 - 400 cubic meters per hour, and the head is 8 - 125 meters.

[0034] It should be noted that: Multiple groups of serpentine water pipes 3 are arranged. By the operation of multiple groups of serpentine water pipes 3, the temperature reduction effect can be improved.

[0035] The honeycomb water flow disperser 5 is composed of criss-cross heat absorption tubes. When the water flow impacts on the heat absorption tubes, it will splash, thus dispersing the water flow. Therefore, when ventilation is carried out, the contact area between the water flow and the flowing air is increased, so that the cooling water can be quickly cooled, improving the subsequent cooling effect.

[0036] Ventilation holes 12 (not marked in the figure) are provided on the first box body 4 and the machine room box body 1. The gas circulates through the ventilation holes 12, thus achieving the heat dissipation effect.

[0037] It should be noted that the ventilation holes 12 provided on the first water tank and the machine room box body 1 can be specifically set as required. The position and quantity of the settings only need to ensure that the gas can circulate, which belongs to the prior art and will not be elaborated here too much.

[0038] The rotating assembly includes a bracket 10 provided on the inner wall of the protective housing 6. A motor 11 is provided on the bracket 10. The output end of the motor 11 is connected to the fan blade 7. The fan blade 7 is driven to rotate by the motor 11, thus achieving heat dissipation and temperature reduction by means of air cooling.

[0039] Among them, two groups of fan blades 7 can be provided and connected by a transmission belt. When the motor 11 rotates, the other group of fan blades 7 is rotated through the transmission belt, so as to provide a greater air flow rate and further improve the cooling effect.

[0040] The working principle of this utility model is as follows: Firstly, when the electrical components inside the machine room box body 1 are working, a large amount of heat will be generated. This heat will enter the rectangular cavity 2, and is absorbed by the serpentine water pipe 3, resulting in the serpentine water pipe 3 having a high temperature. At the same time, the water pump starts, and the water pump makes the cooling water enter through the water inlet of the serpentine water pipe 3. When the water flows inside the serpentine water pipe 3, it will absorb the heat on the serpentine water pipe 3, thereby conducting heat exchange to achieve the heat dissipation effect of the machine room box body 1. Because the serpentine water pipe 3 is set, the heat absorption area can be increased, which can not only improve the heat exchange effect and further increase the heat dissipation area, but also prevent the cooling water from directly contacting the machine room box body 1, avoiding corrosion and prolonging the service life of the machine room box body 1. At the same time, the rotating component drives the fan blade 7 to rotate, thereby providing suction to discharge the heat inside the rectangular cavity 2 through the air duct 8 for secondary heat dissipation. When the water pump makes the cooling water enter through the water inlet of the serpentine water pipe 3 and the water absorbs the heat on the serpentine water pipe 3 during its flow inside the serpentine water pipe 3, the water that has absorbed the heat enters the first box body 4 from the water outlet of the serpentine water pipe 3, and then the water flow drops onto the honeycomb water flow disperser 5 by gravity. The water impacts on the honeycomb water flow disperser 5 to form a dispersed form of the water flow. At this time, because the rotating component drives the fan blade 7, the air flows. At this time, the contact area between the dispersed water flow and the air increases for rapid heat dissipation, thereby improving the cooling effect of the cooling water and enabling it to be reused again. This can not only improve the temperature reduction effect of the machine room box body 1, but also achieve the effect of saving water resources.

[0041] The above is only the preferred embodiment of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
