Description
Technical field
The present invention relates to a kind of oil cooler, particularly a kind of oil cooler that adopts hot pipe technique.
Background technology
The type of cooling of traditional transformer, generally has that Natural Oil Circulation Power air cooling, forced oil-circulation are air-cooled, a forced oil circulation water-cooling etc.Front a kind of situation that is only applicable to unit low capacity, along with the continuous growth of transformer single-machine capacity, its type of cooling is more and more fixed against latter two.The power transformer of present big or middle capacity, its cooler or be gilled radiator or air-cooled cooler, or be water-cooling cooler, use air or water by heat exchanger, to operating transformer oil, to carry out cooling as coolant.But no matter gilled radiator, air-cooled cooler or water-cooling cooler, have its intrinsic defect and problem.
Gilled radiator cost is low, and technique is simple, non-maintaining, and noiselessness is the major advantage that favored by user.But gilled radiator adopts Natural Oil Circulation Power air cooling, and radiating efficiency is low, and volume is large, and floor space is large.Because heat-sinking capability is lower, be only applicable to the occasion of low capacity, cannot meet the demand of high-power transformer.
Air-cooled cooler cost is low, but under the increasing reality of transformer capacity, its cooling effectiveness is more and more not enough, need to set up blower fan.And the caused problem of noise pollution of fan operation is very important, especially, in urban network restructuring or residential block transformer station, fan noise pollutes becomes environmental problem.For avoiding noise pollution, generally forced air cooler is arranged in basement.Because basement space is narrow and small, affect fan radiating, further limited power of fan.On the other hand, the increasing of blower fan, its failure rate and reliability, and also upgrading thereupon of maintenance cost.
To existing water-cooling cooler, its cooling effect is more much better than forced air cooler.But city intake water is restricted, and water rate is more expensive; If use recirculated water, easily produces again incrustation scale in cooler, affect cooling effect.More fatal, if in transformer running, water-cooling cooler leaks, and cooling water leaks into transformer oil side and mixes with transformer oil, very easily causes insulation fault, has a strong impact on the safe operation of transformer.Therefore, someone designs double hose or double-plate water-cooling cooler, the space in the middle of two-tube or two plates is regularly detected, if find that there is oil or water can be found to leak in time, for possible insulation fault provides warning.But the generation that this structure can not avoid water to reveal completely; And the structural design of two-tube or two plates has reduced the heat exchange efficiency of complete machine.
For avoiding the potential safety hazard of water-cooling cooler generation insulation fault, there is people to replace cooling water with the transformer oil of homogeneity, as the coolant of cooler, this cooler is called oily oil cooler.The advantage of oil oil cooler maximum is, even if reveal, leaks into the transformer oil that remains homogeneity of transformer oil side, can not cause that the dielectric in transformer worsens, and has avoided the generation of insulation fault.But coolant is replaced by after transformer oil by water, transformer oil viscosity is ten times of water, and specific heat only has half of water, so the flow velocity of coolant will slow down relatively, and heat absorption capacity also greatly weakens, so the heat transfer effect of complete machine will be had a greatly reduced quality.
Therefore, for retaining the advantage of oily oil cooler, and manage to make up its shortcoming, improve the heat exchange efficiency of oily oil cooler, also there is relevant work both at home and abroad, but be all the principle that adopts specific heat heat exchange, use liquid or gas medium to carry out the secondary of transformer oil coolant cooling, phase-change heat-exchange between liquid state and gaseous state does not occur, so cooling effectiveness is not high.In the number of patent application patent of invention that is 200610032155.9, the oily oil cooler that described transformer is used, be that to use gilled radiator to carry out secondary to the transformer oil as coolant cooling, again adopt the heat exchange of oil-air dielectric, do not undergo phase transition, radiating effect improves limited.
Summary of the invention
The object of the invention is to overcome the not high defect of existing oily oil cooler technology cooling effect, propose a kind of heat-tube type oil cooler that uses liquid medium phase-change heat-exchange, improve the cooling effectiveness of existing oily oil cooler.
