Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cabins, and specifically provides a prefabricated cabin heat dissipation system. Background Art

[0002] A large number of devices are installed in the prefabricated cabin of a conventional substation, and these devices usually generate a lot of heat. Therefore, ventilation fans or ventilation louvers are usually installed on the side walls and top covers of the prefabricated cabin. When the heat generated by the equipment is high, the heat is dissipated from the ventilation fans and ventilation louvers along with the air to achieve the effect of heat dissipation.

[0003] However, if a cabinet with high heat generation is installed in the prefabricated cabin, such as a capacitor cabinet, a reactor cabinet or a rectifier cabinet, it is difficult for these cabinet equipment to take away heat because of the cabinet shell itself. The air entering through the ventilation shutters or fans is blocked by the cabinet shell, and it is difficult to take away the heat. The heat cannot be dissipated, which has a great impact on the operating stability of the equipment in the cabinet. Therefore, the existing prefabricated cabin has the problem of difficulty in dissipating the heat of the cabinet equipment. Utility Model Content

[0004] The utility model provides a prefabricated cabin heat dissipation system, which is used to solve the problem that the heat dissipation of a cabinet in an existing prefabricated cabin is difficult, resulting in poor operating stability of equipment in the cabinet.

[0005] The technical solution of the utility model is as follows:

[0006] A prefabricated cabin heat dissipation system comprises a cabin body, a cabinet body, an air inlet duct and an air outlet duct, wherein the cabinet body is arranged in the cabin body, the air inlet duct passes through the cabin body, the air inlet duct is connected to the cabinet body, and the air outlet duct is connected to the cabinet body.

[0007] In this solution, an air inlet duct and an air outlet duct connected to the cabinet are provided, so that air can enter the cabinet from the air inlet duct, and the air can be discharged from the air outlet duct after heat exchange with the equipment in the cabinet. The air can directly exchange heat with the equipment in the cabinet, which can effectively cool the equipment in the cabinet, solve the problem of heat dissipation difficulty of the equipment in the cabinet, ensure that the temperature of the equipment in the cabinet is not too high, and ensure that the equipment in the cabinet can operate stably.

[0008] The air inlet duct and / or the air outlet duct is provided with a fan.

[0009] In this solution, the fan is provided to increase the air flow speed, increase the contact speed between the air and the equipment in the cabinet, and thus improve the heat dissipation speed of the equipment installed in the cabinet.

[0010] The air outlet duct is provided with a fan, the side wall of the cabin is provided with an air outlet, and the air outlet duct is communicated with the air outlet.

[0011] In this solution, a fan is installed in the air outlet duct to extract the hot air in the cabinet and reduce the pressure inside the cabinet. After the pressure inside the cabinet is reduced, the cold air from the outside will enter the cabinet from the air inlet duct. Installing a fan in the air outlet duct can make the airflow direction in the cabinet more stable, so that the airflow flows toward the position of the fan, avoiding turbulence in the cabinet and ensuring heat dissipation efficiency.

[0012] The fan is connected to the top of the cabinet.

[0013] In this solution, the fan is connected to the top of the cabinet, which can make the installation of the fan more stable and facilitate the installation of the fan.

[0014] An air hood is provided at one end of the air inlet duct away from the cabinet, and air enters through the air hood.

[0015] In this solution, the provision of a hood can facilitate the outside air to enter the air inlet duct, and at the same time the hood can block debris, thereby preventing the debris from entering the air inlet duct and causing blockage of the air inlet duct.

[0016] The height of the hood is lower than the height of the air outlet of the air outlet duct.

[0017] In this solution, the height of the hood is set at the height of the air outlet of the air outlet duct. The air outlet duct discharges hot air after heat exchange with the equipment in the cabinet. Based on the principle that hot air will float up, the hood is set at a position lower than the air outlet of the air outlet duct. This can prevent hot air from being sucked into the air inlet duct, ensuring that cold air enters the air inlet duct, thereby ensuring a cooling effect on the equipment in the cabinet.

[0018] A basic cable trench is arranged at the bottom of the cabin body, and the air inlet duct is arranged along the basic cable trench. One end of the air inlet duct passes through the bottom of the cabin body and is communicated with the cabinet body, and the other end of the air inlet duct extends out of the cabin body.

[0019] In this solution, the air inlet duct is arranged along the basic cable trench and can be constructed together with the basic cable trench. The air inlet duct and the basic cable trench extend in the same direction, which can reduce the construction difficulty and also avoid the air inlet duct affecting other construction.

[0020] The cabinet is sealed inside and outside, so that air flows inside and outside the cabinet only through the air inlet duct and the air outlet duct.

[0021] In this solution, the cabinet is sealed inside and outside, and the air can only be discharged through the air outlet duct, so that the air flow direction is more uniform and turbulence can be avoided. At the same time, the hot air in the sealed cabinet will not be dissipated from the cabinet position, which can prevent the hot air from being dissipated into the prefabricated cabin and causing the temperature in the prefabricated cabin to rise rapidly.

[0022] The air outlet duct is communicated with the top of the cabinet.

[0023] In this solution, the air outlet duct is connected to the top of the cabinet, and the hot air will automatically float up, so that the hot air will automatically flow to the air outlet duct, thereby accelerating the exhaust efficiency of the hot air and enhancing the heat dissipation effect.

[0024] The air inlet duct is communicated with the bottom of the cabinet.

[0025] In this solution, cold air enters the cabinet from the bottom of the cabinet, and will continue to rise after the cold air exchanges heat with the equipment in the cabinet. It will not convect with the air entering from the air inlet duct, so that the cold air in the air inlet duct can enter the cabinet more smoothly.

[0026] Beneficial effects of the utility model:

[0027] The utility model is provided with an air inlet duct and an air outlet duct connected to the cabinet, so that air can enter the cabinet from the air inlet duct, and can be discharged from the air outlet duct after the air exchanges heat with the equipment in the cabinet. The air can directly exchange heat with the equipment in the cabinet, and can effectively dissipate the heat of the equipment in the cabinet, thereby ensuring that the temperature of the equipment in the cabinet will not overheat and ensuring that the equipment can operate stably.

[0035] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0036] Embodiment 1,

[0037] like Figure 1 As shown, the first embodiment of the present invention provides a prefabricated cabin heat dissipation system, including a cabin 1, a cabinet 2, an air inlet duct 6 and an air outlet duct 3. The cabinet 2 is installed in the cabin 1, and the cabinet 2 is used to install equipment. The cabin 1 is installed on a base 8, and the base 8 is provided with an air inlet duct 6. The air inlet duct 6 passes through the bottom of the cabin 1, and the air inlet duct 6 is connected to the bottom of the cabinet 2, and the air outlet duct 3 is also connected to the cabinet 2. Air can enter the cabinet 2 from the air inlet duct 6, and be discharged from the air outlet duct 3 after heat exchange with the equipment in the cabinet 2, so as to achieve the effect of heat dissipation of the equipment in the cabinet 2. During the heat dissipation process, the air directly contacts the equipment in the cabinet 2 and will not be blocked by the shell of the cabinet 2, so the problem of the cabinet 2 shell blocking the heat dissipation can be solved.

[0038] The cabin 1 is fixed on a base 8, and the base 8 can be cast in concrete or constructed of building materials such as bricks.

[0039] In the prior art, a basic cable trench is provided in the base 8, so an air inlet duct 6 can be added along the direction of the basic cable trench. Since the air inlet duct 6 is built on the basis of the basic cable trench, the required construction amount is small and the construction is convenient.

[0040] The air inlet duct 6 can be arranged on the upper side, lower side or both sides of the basic cable trench. Alternatively, the size of the basic cable trench can be increased so that a sufficiently large passage can be retained after the cables are placed in the basic cable trench, so that the passage forms the air inlet duct 6.

[0041] The air inlet duct 6 may include two parts, one is a pipe made of metal or plastic, and the other is a cast channel, the pipe and the channel are combined to form the air inlet duct 6, and the pipe part is used to connect with the cabinet 2. External air enters the pipe through the channel, and then enters the cabinet 2 through the pipe; or, external air enters the pipe at one end, then enters the channel through the pipe, then enters the pipe at the other end through the channel, and finally enters the cabinet 2 through the pipe.

[0042] The air inlet duct 6 can also be a complete pipe, that is, the entire pipe is buried in the cast channel, and the air completely enters the pipe from the outside and then enters the cabinet 2 along the pipe.

[0043] One end of the air inlet duct 6 penetrates from the bottom of the cabin 1 and then communicates with the bottom of the cabinet 2. The other end of the air inlet duct 6 bends upward from the bottom to extend above the ground, so that outside air can enter the air inlet duct 6. The interior of the cabinet 2 is connected to the environment outside the cabin 1 through the air inlet duct 6, and the gas can enter the cabinet 2 from the air inlet duct 6, thereby cooling the equipment in the cabinet 2. The shape of the entire air inlet duct 6 is a U-shaped channel. The cross-sectional shape of the air inlet duct 6 can be circular, elliptical, rectangular, triangular, trapezoidal or diamond-shaped.

[0044] The end of the air inlet duct 6 outside the cabin 1 is provided with a hood 7. The hood 7 can be the hood 7 used in a conventional ventilation channel. The hood 7 can be provided to facilitate air intake and prevent debris and rain from entering the air inlet duct 6 and causing blockage.

[0045] The hood 7 protrudes from the ground and is higher than the ground to prevent water on the ground from flowing into the air inlet duct 6 .

[0046] The air outlet duct 3 is arranged at the top of the cabinet 2, and an air outlet 5 is arranged on the side wall of the cabin 1. One end of the air outlet duct 3 is connected to the top of the cabinet 2, and the other end is connected to the air outlet 5. The hot air in the cabinet 2 flows along the air outlet duct 3 and then is discharged from the air outlet 5. The air outlet 5 is located on the side wall of the cabin 1, so the hot air is directly discharged to the outside of the cabin 1 during discharge, so as to avoid the hot air causing a significant increase in the temperature in the cabin 1.

[0047] The best effect is achieved when the air outlet duct 3 is connected to the top surface of the cabinet 2, and hot air will automatically flow into the air outlet duct 3 from the top surface of the cabinet 2. The air outlet duct 3 can also be connected to the top of the side surface of the cabinet 2, which can also allow hot air to flow in automatically. However, compared with the method of connecting to the top surface of the cabinet 2, the air outlet duct 3 connected to the side surface of the cabinet 2 will occupy horizontal space, affecting the installation of other equipment.

[0048] The air outlet duct 3 is a pipe made of plastic or metal, and the air outlet duct 3 is fixedly connected to the top of the cabinet 2 through fasteners.

[0049] The air outlet duct 3 is provided with a fan 4, which is used to extract the air in the cabinet 2, and accelerate the exhaust efficiency of the hot air in the cabinet 2 through the fan 4. The fan 4 extracts the hot air, which will reduce the air pressure in the cabinet 2, thereby reducing the air pressure in the air inlet duct 6, so that the outside air flows to the air inlet duct 6 in the low-pressure environment.

[0050] The height of the air outlet 5 is higher than that of the hood 7 , so as to prevent the hot air from entering the air inlet duct 6 again from the hood 7 during the rising process after being discharged from the air outlet 5 .

[0051] like Figure 2 and Figure 3As shown, the number of the cabinets 2 can be one, two, three or more. The number of the air inlet ducts 6 corresponds to the number of the cabinets 2, and the air inlet ducts 6 correspond to the cabinets 2 one by one. Each cabinet 2 is respectively provided with an air outlet duct 3, and the cabin 1 is provided with an air outlet 5 at a position corresponding to the air outlet duct 3, and each air outlet duct 3 is respectively connected to the air outlet 5. Each air outlet duct 3 is respectively provided with a fan 4.

[0052] The air inlet ducts 6 may be interconnected or independent of each other.

[0053] The cabinet 2 is sealed from the external environment to prevent hot air in the cabinet 2 from flowing into the cabin 1, thereby preventing the cabin 1 from heating up rapidly.

[0054] Embodiment 2:

[0055] The second embodiment provides a prefabricated cabin heat dissipation system. Different from the first embodiment, the air inlet duct 6 in the second embodiment is also provided with a fan 4.

[0056] The air inlet duct 6 is provided with a fan 4 for blowing gas into the cabinet 2 to accelerate the gas flow, thereby accelerating the heat exchange speed between the equipment in the cabinet 2 and the air and enhancing the heat dissipation effect.

[0057] Embodiment 3,

[0058] The third embodiment provides a prefabricated cabin heat dissipation system. Different from the first embodiment, the end of the air inlet duct 6 of the third embodiment away from the cabinet 2 is not provided with a hood 7, and the end of the air inlet duct 6 away from the cabinet 2 is connected to a blower 4.

[0059] By blowing air into the cabinet 2 through the blower 4 , the effect of inputting air into the cabinet 2 can also be achieved.

[0060] Embodiment 4:

[0061] The fourth embodiment provides a prefabricated cabin heat dissipation system. The difference from the first embodiment is that the air outlet duct 3 of the fourth embodiment is not provided with a fan 4, while the air inlet duct 6 is provided with a fan 4.

[0062] The fan 4 of the air inlet duct 6 blows gas into the cabinet 2, thereby forcing the air in the cabinet 2 to be discharged from the air outlet, thereby achieving the effect of accelerating air flow and enhancing heat dissipation.

[0063] Embodiment 5,

[0064] like Figure 4 As shown, the fifth embodiment provides a prefabricated cabin heat dissipation system. Different from the first embodiment, the air inlet duct 6 of the fifth embodiment is connected to the bottom of the side of the cabinet 2, and the air inlet duct 6 passes through the cabin 1 from the side.

[0065] The air inlet duct is a pipe made of metal or plastic, one end of the pipe is connected to the side of the cabinet 2 through a fastener, the middle of the pipe passes through the cabin 1, and the other end of the pipe is located outside the cabin 1.

[0066] In the fifth embodiment, the air inlet duct 6 is usually fixed, for example, by fixing the pipe with a buckle, and fixing the buckle to the ground. If the cabinet 2 is far away from the ground, a bracket is required to support the pipe.

[0067] The fifth embodiment is also applicable to the second to fourth embodiments.
