Description

Technical Field

[0001] The present invention relates to the field of voltage regulating equipment, and in particular to a radiator of voltage regulating equipment and a heat dissipation method thereof. Background Art

[0002] A transformer is a type of voltage regulating device. It is a static electrical device that uses the principle of electromagnetic induction to transfer electrical energy between circuits of different voltage levels. It consists of two or more windings and a common magnetic core, and can change the voltage and current without changing the frequency of the electrical energy.

[0003] The transformer is mainly composed of a magnetic core, windings, insulation materials and an oil tank. The magnetic core and windings are assembled inside the oil tank, and transformer oil is injected and stored inside the oil tank to provide cooling and insulation. Transformer oil has good insulation properties and can effectively prevent current leakage and short circuits. It forms an insulating layer between the windings and the core of the transformer to protect the equipment from electric shock and damage. The transformer generates a lot of heat during operation. The oil can take away the heat through convection and heat conduction to maintain the normal operating temperature of the transformer. The flow of oil helps to transfer heat from the heat-generating components to the transformer casing, thereby achieving effective heat dissipation.

[0004] The heat dissipation method for the oil inside the transformer is usually to install multiple cooling fins on the outside of the transformer tank to dissipate the heat from the oil. However, this heat dissipation method requires the heat in the oil to be transferred to the tank, and then dissipated through the tank and the cooling fins. As a result, this heat dissipation method is limited. When the transformer is in a high-power working state for a long time, the oil inside the transformer tank will rise. The increase in oil temperature will cause the following problems:

[0005] Degradation of insulation performance: When the oil temperature rises, its insulation performance will decrease, which may cause electrical failures such as breakdown or short circuit, which will seriously affect the safety and reliability of the transformer;

[0006] Oil aging: High temperature will accelerate the oxidation process of transformer oil, causing oil aging and producing acidic substances and sediments. These aging products will reduce the insulation performance of the oil and may cause damage to the insulation material inside the transformer;

[0007] Increased gas generation: Increased oil temperature will lead to increased gas generation. The accumulation of these gases may cause increased internal pressure and even cause safety hazards such as explosion or leakage;

[0008] Reduced cooling effect: High temperature will reduce the cooling capacity of the oil, causing the transformer temperature to rise further, forming a vicious cycle that may lead to overheating and damage to the equipment;

[0009] Reduced efficiency: Due to degraded insulation and reduced cooling capacity, the operating efficiency of the transformer may be affected, resulting in energy loss and increased operating costs.

[0010] Therefore, a heat sink for a voltage regulating device and a heat dissipation method thereof are proposed to solve or alleviate the above problems. Summary of the Invention

The heat dissipation component 4 is arranged on the heat dissipation shell 2. The heat dissipation component 4 is used to dissipate the coolant transferred to the inside of the heat dissipation shell 2 by the heat exchange component 3. The heat dissipation component 4 can cool the coolant inside the heat dissipation shell 2, thereby ensuring the efficiency of the coolant absorbing the heat in the oil inside the transformer body 1 through the heat exchange component 3. A temperature sensor is installed inside the transformer body 1 for collecting the heat of the oil inside the transformer body 1. The temperature sensor transmits the collected data to an external host computer through wireless transmission technology.

[0080] In particular, the heat exchange assembly 3 includes a heat exchange tube 31, a heat conducting fin 32, a return pipe 33, a connecting cap 35, a drainage hole 37, a liquid injection pipe 34 and a water pump 36.

The air filter element 452 is clamped between the mounting shell 451 and the side cover 42. An air inlet is provided on the back of the side cover 42. The dust screen 453 is fixedly installed in the air inlet. The dust screen 453 and the air filter element 452 can filter the air entering the interior of the mounting shell 451. The gas is filtered to reduce the content of dust in the outside air mixed into the coolant when the cooling fan 44 cools the coolant.

Figure 4 and Figure 5 As shown, there is a certain gap between the mounting shell 451 and the ventilation shell 43, so that the mounting shell 451 can drive the connecting sleeve 454 to slide relative to the connecting pipe 455, so that the mounting shell 451 can be slid and separated from the side cover 42, so as to facilitate the disassembly of the air filter element 452, and the sealing leather sleeve is fixedly sleeved on the inside of the connecting sleeve 454, and the sealing leather sleeve is sleeved on one end of the outer wall of the connecting pipe 455.

[0087] The water pump 36 and the cooling fan 44 are controlled by an external host computer, which is installed on the back of the transformer body 1. The host computer has a temperature judgment system. When the oil temperature inside the transformer body 1 rises to a certain temperature, the host computer controls the water pump 36 and the cooling fan 44 to work, so that the heat exchange component 3 cooperates with the heat dissipation component 4 to cool the oil inside the transformer body 1. The temperature judgment system also includes an oil quality judgment module, which is calculated by the following formula:

[0088]

[0089] is the temperature rise of the oil, is the transformer power loss, is the mass of the oil, The specific heat capacity of the oil is one of its important thermophysical properties. It affects the ability of the oil to dissipate heat and change temperature in the transformer. The specific heat capacity of the oil is a constant value. Therefore, by detecting the temperature increase of the oil through the temperature sensor, the quality of the oil can be reversely calculated to calculate whether the quality of the oil has deteriorated or damaged. This can facilitate the subsequent replacement of the oil inside the transformer body 1 based on whether the quality of the oil has deteriorated.

[0090] The present invention also provides a heat dissipation method for a voltage regulating device, comprising the following specific steps:

[0091] Step 1: When the temperature of the oil in the transformer body 1 rises to a certain value, the water pump 36 delivers the coolant in the heat dissipation housing 2 to the interior of the heat exchange tube 31 through the liquid injection pipe 34. The coolant in the heat exchange tube 31 absorbs heat from the oil in the transformer body 1 through the heat conduction fins 32 and the heat exchange tube 31, and then is discharged into the interior of the heat dissipation housing 2 through the drainage hole 37 on the liquid return pipe 33.

[0092] Step 2: When coolant is discharged from the drain hole 37 on the liquid return pipe 33, the cooling fan 44 exhausts the gas inside the ventilation housing 43 to cool the coolant discharged from the drain hole 37. Under the action of negative pressure, the outside air is filtered by the dust screen 453 and the air filter element 452, and then enters the interior of the ventilation housing 43 through the installation housing 451, the connecting sleeve 454 and the connecting pipe 455.

[0093] Step 3: When disassembling and cleaning the dust screen 453 and the air filter element 452, rotate the locking plate 466 to separate it from the snap-on part 465, and then you can directly slide the side cover 42 and the top cover 41 to separate them from the heat dissipation shell 2, and then slide the installation shell 451 to separate it from the side cover 42. The installation shell 451 drives the connecting plate 459 and the locking rod 4510 to slide through the connecting rod 4511, and separates the locking rod 4510 from the connecting block 458 and the connecting frame 457. Then you can disassemble the installation shell 451 and the ventilation shell 43, and clean and maintain the dust screen 453 and the air filter element 452.

[0094] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
