Description
Technical field
The utility model relates to a kind of cooling device of power equipment, especially relates to a kind of cooling device of large-scale power transformer.
Background technology
Oily circulation self cool heat radiation pipe racking device is adopted in the cooling of transformer mostly, large-scale power transformer adopts the air-cooled structure of forced circulation, and the high temperature oil of coming out from transformer enters in the tube chamber, by the bellows air blast, realize heat exchange, common heat exchanger tube is housed in the heat exchange box, owing to be subjected to the restriction of heat exchange box size, the layout quantity of heat exchanger tube has been subjected to very big restriction, cause heat exchange area little, thereby heat exchange efficiency is low, and does not adopt sealing between fuel tank and the heat exchange bobbin carriage, causes leakage of oil serious.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of heat exchange efficiency height, the cooling device of oil tight large-scale power transformer.
The utility model is realized in the following way:
A kind of cooling device of large-scale power transformer, comprise that one has the fuel tank and the heat exchange box of oil inlet and outlet, between above-mentioned fuel tank and the heat exchange box dividing plate is arranged, heat exchange box is furnished with a bellows, it is characterized in that: be furnished with at least two in this heat exchange box and arrange independently heat pipe, the heat absorbing end of every heat extraction pipe is positioned at fuel tank, and release end of heat is positioned at heat exchange box, and all be furnished with the Oil Guide dividing plate between the heat absorbing end of every heat extraction pipe in the fuel tank, the every heat pipe and the dividing plate touching position that pass dividing plate all have a sealing ring.
On the heat absorbing end of described heat pipe rectangular fin is arranged.
On the part of described heat pipe in described heat exchange bobbin carriage fin is arranged.
Described heat pipe is staggered.
Described heat pipe is four rows.
Described heat pipe is five rows.
The utility model has following effect:
1) simple in structure, easy to make: the cooling device that the utility model provides, the common heat exchanger tube with in original heat exchange box changes heat pipe into and gets final product, and the dividing plate between fuel tank and the heat exchange box is sealed.
2) cooling effectiveness height, cooling rate are fast: the cooling device that the utility model provides, owing to adopt heat pipe, heat pipe is a kind of high efficient heat exchanging element, the one end is a heat absorbing end, and the other end is a release end of heat, and heat absorbing end is positioned at fuel tank, oily heat in the fuel tank is fully absorbed, in order to help further strengthening the heat exchange effect, the heat absorbing end of heat pipe is provided with rectangular fin, further increases heat exchange area.Heat pipe cooler can be adjusted cold and hot side heat exchange area ratio easily, thereby improves cooling effectiveness to a greater extent.Utilize the isothermal characteristics of heat-pipe elements, can improve the outlet temperature of cooling fluid greatly, reduce the cool stream scale of construction.
3) oil-proof: from heat pipe and general heat pipe more as can be known, owing to adopt seal diaphragm between fuel tank and heat exchange box, heat pipe has only a seal point in this device, the possibility of leakage of oil is thoroughly stopped in the not influence of expanded by heating.
4) make full use of heat: in this cooling device, heat exchange box is in air, and in the use, the release end of heat of heat pipe is with its heat and by the abundant heat exchange of cold air around it, with the cold air heating, as other purposes.
5) easy to maintenance: because cold fluid and hot fluid is by the heat exchange of heat pipe cooler different parts, and heat-pipe elements is independently mutually, even therefore certain root heat pipe failure is arranged, how many perforation can not have influence to isolation between cold and hot fluid and heat exchange yet.
6) noise is low: this apparatus structure is simple, and the heat exchange efficiency height is under the condition of transmitting identical heat, the metal consumption of heat pipe cooler is less than the cooler of other types, pressure loss when heat exchanging fluid passes through cooler is littler than other coolers, and power consumption is also little, thereby noise is low.
