However, in the existing water-cooling heat dissipation device, the water flow flows along the transformer in one direction, taking the water flow flowing from bottom to top as an example: the water flow is cold water at the lowest end, and the water flow absorbs more and more heat and the temperature of the water flow is also more and more hot along with the gradual upward flow of the water flow. While at high water temperatures, the amount of heat absorbed is clearly not as great as at low water temperatures. Therefore, the heat dissipation effect of the upper part of the transformer is far inferior to that of the lower part, which causes unbalanced heat dissipation of the transformer, causes higher working pressure of the part with poor heat dissipation of the transformer, easily causes damage of the transformer, reduces the overload capacity of the transformer, and shortens the service life of the transformer. Not only seriously affecting normal use, but also even endangering property and life safety.

When using, start water pump 10, in water pump 10 takes out cold water pipe 7 with the distilled water of the interior normal atmospheric temperature of water tank 4, rivers from cold water pipe 7 through the first water inlet of water-cooling jacket 2 in flowing into water-cooling jacket 2, water-cooling jacket 2 is the aluminum alloy material, and the aluminum alloy has good heat conductivity. Heat generated by the transformer 1 is transferred to water flow through the water cooling jacket 2, and water flow is changed from normal-temperature water to hot water and is collected into the hot water pipe 8 through the first water outlet of the water cooling jacket 2. Due to the back pressure valve 11, when the pressure in the hot water pipe 8 is higher than the set pressure of the back pressure valve 11, water can flow from the hot water pipe 8 into the heat sink 3 through the second water inlet of the heat sink 3.

Through the process, distilled water forms a circulation, and the purpose of cooling the transformer 1 through water cooling circulation is achieved.
When the transformer 1 is in a high overload state for a long time, an over-high temperature state may occur, which may cause the transformer 1 to explode and catch fire, which may endanger the safety of people's lives and property. When such extreme conditions occur, the plug 6 will melt because the temperature of the transformer 1 has now reached or exceeded the melting point of the plug 6. Certainly, under the action of water flow, the part of the plug 6 in contact with water may not be melted, but the end part of the plug 6 is inevitably melted, the strength of the plug 6 at this time is far from reaching the normal strength, and under the high-pressure state of the water pressure in the water cooling jacket 2, half of the plug 6 is melted by the water flow and is flushed out of the water spray pipe 5, so that the water flow is sprayed onto the shell of the transformer 1 from the water cooling jacket 2 through the water spray pipe 5. At this time, the water pressure in the cold water pipe 7, the water cooling jacket 2 and the hot water pipe 8 drops, and the set pressure of the back pressure valve 11 is not reached, so that the distilled water is entirely sprayed onto the housing of the transformer 1 through the water spray pipe 5. When the normal temperature water is sprayed on the shell of the transformer 1, the normal temperature water can be quickly evaporated at a high temperature state, a large amount of heat of the transformer 1 is taken away, and the purpose of forced cooling is achieved. Since the distilled water is not conductive and only sprays on the shell of the transformer 1, which is equivalent to the state that the transformer 1 is drenched, the dangerous situation of leakage of the transformer 1 can not be caused.
When the temperature of the transformer 1 is lowered to the safe temperature, a professional wears a professional, and a new plug 6 is screwed on the spray pipe 5 to plug the spray pipe 5 again. The plug 6 can be melted only in the rare high-temperature state of the transformer 1 for a few times, so that the transitional use of distilled water can not be caused. And even though the manufacturing cost of the distilled water is high, the cost of the distilled water is well within an acceptable range in comparison with the economic property loss and life safety caused by explosion and fire of the transformer 1.
The invention can uniformly radiate the transformer, so that all parts of the transformer can be uniformly radiated, the defects of the traditional water circulation radiator are overcome, and the advantage of water circulation radiation is greatly improved. In addition, when the transformer reaches the high-temperature limit and is in an extreme state before the transformer is burnt, the water spraying device can directly spray water to the transformer, and the water is quickly evaporated on the surface of the transformer to play a role in forcibly cooling, so that the burning of the transformer is avoided, the maintenance cost is greatly reduced, and the property and life safety are protected.
