Technical Field

[0001] This utility model relates to an external circulation heat dissipation device for dry-type transformers, belonging to the field of electrolytic aluminum production technology. Background Technology

[0002] Electrolytic aluminum requires sufficient and stable electrical energy, and transformers are key components to ensure power stability. At present, dry-type transformers in power systems generally only use cross-flow cooling fans to circulate and dissipate heat from each core of the transformer windings. Due to the high ambient temperature in some distribution rooms, relying solely on cross-flow fans cannot meet the heat dissipation requirements inside the transformer. If this continues, when the overall temperature inside the dry-type transformer becomes too high, it can easily cause line tripping, which in turn can lead to power outages in production facilities.

[0007] Furthermore, the air-cooling module includes a fan, the air outlet of which is connected to the air inlets of the first and second nozzles via a pipeline.

[0008] The first nozzle is positioned outside the cooling oil tank; the second nozzle is positioned on one side of the cooling plate.

[0009] Furthermore, a plurality of first heat sinks are provided on the outer surface of the heat sink; a first gap is formed between the first heat sinks.

[0010] The airflow output direction of the first nozzle is parallel to the extension direction of the first gap.

[0011] Furthermore, a plurality of second heat sinks are provided on the side of the heat sink, and a second gap is formed between the second heat sinks;

[0013] Furthermore, the air outlets of the first and second nozzles are flat.

[0014] Furthermore, the dry-type transformer is provided with ventilation openings on its side.

[0026] like Figure 1-3 As shown, this embodiment is achieved through the following technical solution: it includes a dry-type transformer 5, including a liquid-cooled module 1 and an air-cooled module 2, the liquid-cooled module 1 and the air-cooled module 2 are disposed on the outside of the dry-type transformer 5; a heat dissipation oil tank 3 is attached to the side of the dry-type transformer 5, and the heat dissipation oil tank 3 is connected to the heat dissipation plate 4.

[0027] The liquid cooling module 1 is connected to the heat dissipation oil tank 3 by a pipeline; the exhaust end of the air cooling module 2 is connected to the heat dissipation oil tank 3 and the heat sink 4 respectively.

[0028] Both the cooling oil tank 3 and the cooling plate 4 are made of aluminum alloy. The smooth side of the cooling oil tank 3 without the first heat sink 301 is attached to the outer surface of the dry-type transformer 5, ensuring sufficient contact area between them. The cooling plate 4 is clipped onto the cooling oil tank 3, and the cooling plate 4 is connected to the cooling oil tank 3 in multiple places, which facilitates the transfer of some heat from the cooling oil tank 3 to the cooling plate 4. A gap is left between them to allow air to pass through between the cooling oil tank 3 and the cooling plate 4.

[0029] Specifically, the liquid cooling module 1 includes: a circulating pump 101 and a cooling tank 102; the inlet of the circulating pump 101 is connected to the cooling tank 102, the outlet of the circulating pump 101 is connected to one end of the heat pipe 103, and the other end of the heat pipe 103 is connected to the cooling tank 102, the three together forming a circulating liquid circuit; the heat pipe 103 is installed inside the heat dissipation oil tank 3.

[0030] The heat pipe 103 and the heat dissipation oil tank 3 are isolated from each other. In this embodiment, the heat dissipation oil tank 3 is filled with heat-conducting oil, and the above-mentioned circulating fluid circuit is sealed with coolant. The heat pipe 103 carries away part of the heat from the heat dissipation oil tank 3 through the coolant. The coolant flows from the heat pipe 103 into the cooling box 102. The cooling box 102 is used to dissipate the heat of the coolant. The cooling box 102 is set in a low-temperature environment.

[0031] Specifically, the air-cooled module 2 includes: a fan 201, the air outlet of which is connected to the air inlet of the first nozzle 202 and the second nozzle 203 via a pipeline;

[0032] The first nozzle 202 is located on the outside of the cooling oil tank 3; the second nozzle 203 is located on one side of the cooling plate 4.

[0033] Specifically, a plurality of first heat sinks 301 are provided on the outer side of the heat sink 3; a first gap is formed between the first heat sinks 301;

[0034] The airflow from the first nozzle 202 blows onto the first heat sink 301. The airflow output direction of the first nozzle 202 is parallel to the extension direction of the first gap. The airflow passes through the first gap and carries away part of the heat from the cooling oil tank 3.

[0035] Specifically, a number of second heat sinks 401 are provided on the side of the heat sink 4, and a second gap is formed between the second heat sinks 401.

[0036] Some of the heat from the cooling oil tank 3 is transferred to the heat sink 4. The airflow from the second nozzle 203 blows towards the second heat sink 401. The airflow output direction of the second nozzle 203 is parallel to the extension direction of the second gap. The airflow passes through the second gap and carries away some of the heat from the heat sink 4.

[0037] The air outlets of the first nozzle 202 and the second nozzle 203 are flat.

[0038] The dry-type transformer 5 has a ventilation opening 501 on its side.

[0039] The specific operating principle of the device is as follows: The cooling oil tank 3 is in direct contact with the dry-type transformer 5. The heat of the dry-type transformer 5 is transferred to the heat-conducting oil in the cooling oil tank 3. The circulating liquid circuit of the liquid cooling module 1 carries away part of the heat of the cooling oil tank 3. The heat is further transferred to the first heat sink 301 and the heat sink 4 connected to the cooling oil tank 3. The air cooling module 2 blows airflow to the first heat sink 301 and the second heat sink 401 through the first nozzle 202 and the second nozzle 203, thereby realizing the air cooling of the cooling oil tank 3 and the heat sink 4. The device enhances the heat dissipation of the dry-type transformer 5 through both liquid cooling and air cooling.
