Description
Technical field
The utility model relates to power domain, is meant a kind of forced-oil-air cooling radiator cooler especially.
Background technology
Flourish along with power domain, transformer is extensively used, and wherein cooling device plays an important role.At present, the radiating tube of existing forced-oil-air cooling radiator cooler adopts the iron Al bimetal to roll finned tube, and promptly the radiating tube body is an iron pipe; This iron pipe outer wall is arranged with the finned tube that rolls of aluminum, and such structure causes the finned tube that rolls of iron pipe and aluminum to have the slit, and both coefficients that expands with heat and contract with cold are different; Under the situation of being heated or catching a cold; Slit between the two must be strengthened, so that produces hot estrangement, and the thermal transmission coefficient of iron is far below the thermal transmission coefficient of aluminium in addition; And with oil directly contact for iron pipe, cause overall cooling effect not good; The heat exchanger tube of iron produces oxide layer in the mill in addition, and the later stage is difficult to thoroughly remove, and makes transformer oil produce secondary pollution and lowers the oil product insulation, influences the safe operation of transformer.
The utility model content
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of good heat dissipation effect and the difficult forced-oil-air cooling radiator cooler that causes secondary pollution.
The technical scheme of the utility model is achieved in that a kind of forced-oil-air cooling radiator cooler; Comprise radiating tube, be sheathed on radiating tube and be positioned at grease chamber's oil collection plate of radiating tube end and be sheathed on radiating tube and grease chamber's fixed head that adjacent oil collection plate is provided with; Described radiating tube is that aluminium is made; The lateral wall integral type of this radiating tube be provided with some aluminiums made roll fin, this rolls fin near grease chamber's fixed head, and extends along the length direction of radiating tube and to be provided with.
Through adopting technique scheme, change the conventional iron Al bimetal and rolled finned tube structure, adopt single aluminum material made, because of the thermal transmission coefficient of aluminium several times of iron; Cooling effect improves greatly, and cost performance is high, at equal cooling capacity; Can reduce the number of heat exchanger tube, adopt aluminum material rolling because of radiating tube is whole, no heat transfer estrangement; Non-oxidation layer during manufacturing has reduced the secondary pollution of transformer, improves the coefficient of the safe operation of transformer.
The utility model further is set to: described grease chamber oil collection plate is provided with the mouth of pipe that supplies radiating tube to lay; The edge of this mouth of pipe turns up along the length direction of radiating tube; Constitute trumpet-shaped expansion loop; And the end face of the end face of this mouth of pipe and the radiating tube mouth of pipe is positioned on the same plane, and both ends of the surface adopt argon welding to be fixedly connected.
Through adopting technique scheme, prevent that radiating tube from expanding with heat and contract with cold and weld generation stress rupture grease chamber oil collection plate.
The utility model further is set to: described radiating tube outer wall is provided with the fixture that prevents that grease chamber's fixed head from moving along the radiating tube length direction.
Wherein, described fixture is two annular boss, lays respectively at the both sides of grease chamber's fixed head length direction, and is provided with the radiating tube integral type.
Through adopting technique scheme, prevent that grease chamber's fixed head from moving along the radiating tube length direction, plays fixation.
