Description

Transformer radiator

technical field

The utility model relates to a radiator, in particular to a transformer radiator.

Background technique

In the heat dissipation process of existing transformers, some adopt the way of air-conditioning cold air to dissipate heat. However, in the existing way of using cold air to dissipate heat, the time for the cold air to contact the side wall of the transformer is short, and the heat dissipated by the transformer passes through the cold air. The efficiency of air removal is not high. The temperature difference between the hot air coming out of the air outlet and the cold air coming in from the air inlet is not large. Therefore, the air conditioner is required to work continuously to provide cooling.

Utility model content

In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is to provide a transformer radiator.

In order to achieve the above object, the utility model provides a transformer radiator, including a heat dissipation part, the heat dissipation part is a hollow structure, a first graphite rod is arranged in the inner cavity of the heat dissipation part, and heat dissipation fins are evenly distributed on the outer wall of the heat dissipation part. The heat sink passes through the outer wall of the heat dissipation part and contacts the graphite rod. The end face of the heat dissipation part is provided with a liquid outlet, and the other end of the heat dissipation part is connected to the right end of the heat pipe. The inner chamber of the heat pipe is connected, the heat pipe is provided with a liquid injection hole, the inner chamber of the left end of the heat pipe is provided with a second graphite rod, and the ring-shaped outer wall of the left end of the heat pipe is evenly distributed with heat conduction sheets. The heat conduction sheet contacts the second graphite rod through the outer wall of the heat conduction pipe.

With the above structure, the inner cavity of the cooling part and the inner cavity of the heat transfer tube can be filled with the heat transfer fluid medium through the liquid injection hole, and the left end of the heat transfer tube is inserted into the oil-immersed transformer box. The heat is dissipated through the heat sink; the fluid medium has a large specific heat capacity, which can store more heat; when the temperature needs to be cooled quickly, the liquid can be injected and discharged through the peripheral device at the same time, so that the heat transfer fluid medium circulates and improves Heat dissipation effect: the thermal conductivity of the first graphite rod and the second graphite rod is relatively high, which can conduct heat better.

Preferably, the cooling fins are distributed radially around the axis of the first graphite rod, the cooling fins are fan-shaped, and the bottom of the cooling fins is in contact with the first graphite rod through the first connecting shaft. There are gaps between the heat sinks in this structure, and the heat transfer fluid medium inside the cavity completely surrounds the heat sink to enhance the heat conduction effect; the heat sink outside the cavity is easier to dissipate heat, and its heat dissipation effect is good.

Preferably, the heat conduction sheets are distributed radially around the axis of the second graphite rod, the heat conduction sheets are fan-shaped, and the bottom of the heat conduction sheet is in contact with the second graphite rod through the second connecting shaft. There are gaps between the heat conduction fins in this structure, and the heat conduction fluid medium inside the cavity completely surrounds the heat sink to enhance the heat conduction effect.

Preferably, a protective net is arranged on the periphery of the heat conducting sheet. The protective net can prevent the heat conduction sheet from scratching the equipment inside the transformer box.

The beneficial effects of the utility model are: the utility model greatly improves the cooling effect through the heat-conducting fluid medium; and the utility model has the advantages of simple structure, low cost, and convenient use and installation.
