Description

Technical Field

[0001] This application relates to the technical field of high-voltage electrical equipment, and in particular to a high-voltage electrical equipment radiator. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in a power system. The basic elements include: (1) Electrical insulation: Maintaining good insulation of power distribution lines and electrical equipment is the most basic element to ensure personal safety and normal operation of electrical equipment. Whether the electrical insulation performance is good can be measured by measuring parameters such as insulation resistance, withstand voltage, leakage current and dielectric loss; (2) Safe distance: Electrical safety distance refers to the safe and reliable distance between a person, an object, etc., and a live conductor without causing danger, such as the distance between a live conductor and the ground, between live conductors, and between a live conductor and the ground. A certain distance should be maintained between human bodies and between live parts and other facilities and equipment. When working near power distribution lines and transformers and distribution equipment, the safety distance of the line, the safety distance of the transformers and distribution equipment, the maintenance safety distance and the operation safety distance should be considered. (3) Safe current carrying capacity: The safe current carrying capacity of a conductor refers to the amount of current that can continuously pass through the conductor. If the current continuously passing through the conductor exceeds the safe current carrying capacity, the conductor will heat up beyond the allowable value, leading to insulation damage, or even leakage and fire. Therefore, it is very important to determine the conductor cross-section and select equipment based on the conductor's safe current carrying capacity.

[0003] Currently, high-voltage electrical equipment requires radiators to dissipate the heat generated during daily use. Radiators typically consist of a base and heat dissipation fins mounted on the base, which dissipate heat.

[0004] The inventors believe that the existing technology has the defect that when the temperature of the heat dissipation fins is high during use, the heat dissipation effect of the heat dissipation fins will be poor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a high-voltage electrical equipment radiator. This high-voltage electrical equipment radiator can improve the heat dissipation effect of the heat dissipation fins.

[0006] This application provides a high-voltage electrical equipment radiator, which adopts the following technical solution:

[0007] A high-voltage electrical equipment radiator includes a base and a plurality of heat dissipation fins disposed on the base. A cooling device is provided on the base. The cooling device includes a heat dissipation bladder disposed between two adjacent heat dissipation fins for cooling the heat dissipation fins and a liquid supply assembly disposed on the base for supplying coolant to the heat dissipation bladder. The heat dissipation bladder is provided with a cavity for storing coolant. The liquid supply assembly is connected to the heat dissipation bladder.

[0008] Optionally, the liquid supply assembly includes a liquid supply tank disposed on the base, a delivery pipe connected to the heat sink, and a liquid supply pump for delivering coolant from the liquid supply tank to the delivery pipe, wherein the delivery pipe is connected to the heat sink.

[0009] Optionally, the heat sink is made of elastic rubber material, and the delivery pipe delivers coolant to the heat sink, causing the heat sink to expand and deform.

[0010] Optionally, the base is provided with two limiting plates, which are located at both ends of the heat sink in the vertical direction and are used to limit the heat sink.

[0011] Optionally, a guide groove is provided on the limiting plate located at the top of the heat sink, and the delivery pipe is slidably fitted in the guide groove.

[0012] Optionally, the conveying pipe is provided with a slider, the slider is slidably engaged with the guide groove, and an elastic element for driving the slider to reset is provided between the slider and the limiting plate.

[0013] Optionally, the delivery pipe includes an outer delivery pipe connected to the liquid supply pump and an inner delivery pipe that slides within the outer delivery pipe.

[0014] Optionally, a temperature sensor is installed on the heat dissipation fins, and the temperature sensor is electrically connected to a controller. The controller is electrically connected to the liquid supply pump and is used to control the start and stop of the liquid supply pump.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. Through the cooling device, the liquid supply component delivers coolant to the heat sink, which cools the heat sink fins on both sides of the heat sink, thereby achieving rapid cooling of the heat sink fins and improving the heat dissipation effect of the heat sink fins.

[0017] 2. After the radiator is filled with coolant, it expands and deforms, which improves the contact between the radiator and the radiator fins. When the radiator is no longer filled with coolant and cooling is completed, the radiator can return to its original shape. At the same time, the coolant in the radiator will be squeezed and flow back into the coolant supply tank, which makes it easier to collect the coolant.

[0018] 3. By setting the limiting plate, the deformation of the heat sink can be limited, reducing the large deformation of the heat sink in the vertical direction. Attached Figure Description

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] This application discloses a radiator for high-voltage electrical equipment. (Refer to...) Figure 1 and Figure 2 It includes a base 1 and multiple heat dissipation fins 2 fixedly installed on the base 1. The multiple heat dissipation fins 2 are spaced apart along the horizontal direction. A cooling device 3 is provided on the base 1, which is used to cool down the heat dissipation fins 2.

[0026] Reference Figure 1 and Figure 2 The cooling device 3 includes a heat sink 31 for cooling the heat sink fins 2 and a liquid supply assembly 32 for supplying coolant to the heat sink 31. The heat sink 31 is disposed between two adjacent heat sink fins 2 and has a cavity for storing coolant. The heat sink 31 is made of elastic rubber material.

[0027] Reference Figure 1-Figure 3The coolant supply assembly 32 is mounted on the base 1 and is connected to the heat sink 31. The coolant supply assembly 32 includes a coolant tank 321 fixedly mounted on the base 1, a delivery pipe 322 connected to the heat sink 31, and a coolant supply pump 323 for delivering coolant from the coolant tank 321 to the delivery pipe 322. The coolant supply pump 323 is fixedly mounted on the base 1, and the delivery pipe 322 is fixedly connected to the heat sink 31. The delivery pipe 322 delivers coolant to the heat sink 31, causing the heat sink 31 to expand and deform.

[0028] Reference Figure 1-Figure 3 The delivery pipe 322 includes an outer delivery pipe 3221 fixedly connected to the liquid supply pump 323 and an inner delivery pipe 3222 slidably fitted within the outer delivery pipe 3221. The inner delivery pipe 3222 is fixedly connected to the top end of the heat sink 31, and the two are in communication. A temperature sensor 7 is fixedly installed on the heat sink fins 2. The temperature sensor 7 is electrically connected to a controller, which is electrically connected to the liquid supply pump 323 and is used to control the start and stop of the liquid supply pump 323.

[0029] Reference Figure 1 and Figure 2 Two limiting plates 4 are fixedly installed on the base 1, located at both ends of the heat sink 31 in the vertical direction, and are used to limit the heat sink 31. A guide groove 41 is opened on the limiting plate 4 at the top of the heat sink 31. A slider 5 is fixedly installed on the delivery pipe 322, and the slider 5 is slidably engaged with the guide groove 41. The delivery pipe 322 is slidably engaged with the guide groove 41 through the slider 5. An elastic element 6 is provided between the slider 5 and the limiting plate 4 to drive the slider 5 to reset. The elastic element 6 is directly a spring, with one end fixedly connected to the slider 5 and the other end fixedly connected to the limiting plate 4.

[0030] The implementation principle of the high-voltage electrical equipment heat sink of this application is as follows: During the use of the heat sink fins 2, when the temperature sensor 7 detects that the temperature of the heat sink fins 2 is high, the temperature sensor 7 transmits the signal to the controller. The controller controls the liquid supply pump 323 to work. The liquid supply pump 323 draws the coolant from the liquid supply tank 321 and delivers the coolant through the outer delivery pipe 3221 and the inner delivery pipe 3222 in sequence to the heat sink 31. When the coolant is continuously input, the heat sink 31 expands and deforms horizontally due to the limiting plates 4 and the two heat sink fins 2 limiting the heat sink 31. The heat sink 31 fully contacts the heat sink fins 2 and covers the entire side of the heat sink fins 2. During the deformation of the heat sink 31, the inner delivery pipe 3222 slides and adjusts within the outer delivery pipe 3221, and the slider 5 slides within the guide groove 41, stretching the elastic element 6. At this time, the heat sink 31 cools and lowers the temperature of the heat sink fins 2.

[0031] When the heat sink fins 2 cool down, the temperature sensor 7 transmits a signal to the controller, which then shuts off the liquid supply pump 323. At this time, the elastic element 6 releases its elastic restoring force, causing the slider 5 to slide within the guide groove 41. Simultaneously, since the heat sink 31 is no longer filled with coolant, it also releases its elastic restoring force, causing the inner delivery tube 3222 to reset. During the reset process, the coolant inside the heat sink 31 is squeezed, allowing it to flow back into the liquid supply tank 321 after passing through the inner delivery tube 3222 and the outer delivery tube 3221, thus completing the cooling operation of the heat sink fins 2.
