Description

A kind of heat pipe-type oil cooler
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 has generally that Natural Oil Circulation Power air cooling, forced oil-circulation are air-cooled, a forced oil circulation water-cooling etc.Before a kind of situation that is applicable to the unit low capacity, along with the continuous growth of transformer single-machine capacity, its type of cooling more and more is fixed against back two kinds.The power transformer of present big or middle capacity, its cooler or be gilled radiator or air-cooled cooler, or be the water-cooled cooler, promptly use air or water through heat exchanger operating transformer oil to be cooled off as coolant.But no matter gilled radiator, air-cooled cooler still are the water-cooled cooler, and its intrinsic defective and problem is all arranged.
The gilled radiator cost is low, and technology is simple, and is non-maintaining, and noiselessness is the major advantage that favored by the user.But gilled radiator adopts the Natural Oil Circulation Power air cooling, and radiating efficiency is low, and volume is big, and floor space is big.Because heat-sinking capability is lower, only be applicable to the occasion of low capacity, can't satisfy 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 set up blower fan.And the caused noise pollution problem of fan operation is very important, and especially in urban network restructuring or residential block transformer station, fan noise pollutes becomes environmental problem.For avoiding noise pollution, generally be installed in forced air cooler in the basement.Because basement space is narrow and small, influence the blower fan heat radiation, further limited power of fan.On the other hand, blower fan increases its failure rate and reliability, and also upgrading thereupon of maintenance cost.
To existing water-cooled cooler, its cooling effect is more much better than forced air cooler.But the city water intaking is restricted, and water rate is more expensive; If use recirculated water, be prone to again in the cooler produce incrustation scale, influence cooling effect.More fatal is, if in the transformer running, the water-cooled cooler leaks, and cooling water leaks into the transformer oil side and mixes with transformer oil, very easily causes insulation fault, has a strong impact on the safe operation of transformer.Therefore, the someone designs double hose or double-plate water-cooled cooler, the space in the middle of two-tube or two plates is regularly detected, if find to have oil or water then can in time find to leak, for possible insulation fault provides warning.But the generation that this structure can not avoid water to reveal fully; 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-cooled cooler generation insulation fault, there is the people to replace cooling water with the transformer oil of homogeneity, as the coolant of cooler, this cooler is called oily oil cooler.Oil oil cooler biggest advantage is, even reveal, leaks into the transformer oil that remains homogeneity of transformer oil side, can not cause that the dielectric in the transformer worsens, and has avoided the generation of insulation fault.After but coolant was replaced by transformer oil by water, the transformer oil viscosity was ten times of water, and specific heat has only the half the of water, so the flow velocity of coolant will slow down relatively, and heat absorption capacity also greatly weakens, so the heat exchange effect of complete machine will be had a greatly reduced quality.
Therefore, for keeping the advantage of oily oil cooler, and manage to remedy its shortcoming; Improve the heat exchange efficiency of oily oil cooler; Relevant work is also all arranged both at home and abroad, but all be the principle that adopts the specific heat heat exchange, use liquid or gas medium to carry out the secondary cooling of transformer oil coolant; Phase-change heat-exchange between liquid state and gaseous state does not take place, so cooling effectiveness is not high.Be in 200610032155.9 the patent of invention like number of patent application; The oily oil cooler that said transformer is used; Promptly be to use gilled radiator that the transformer oil as coolant is carried out the secondary cooling; Promptly adopt oil-air dielectric heat exchange once more, do not undergo phase transition, radiating effect improves limited.
Summary of the invention
The objective of the invention is to overcome the not high defective of existing oily oil cooler technology cooling effect, propose a kind of heat pipe-type oil cooler that uses the liquid medium phase-change heat-exchange, improve the cooling effectiveness of existing oily oil cooler.
The present invention utilizes the thermogenetic powerful radiating efficiency of liquid evaporation liquid medium phase inversion of high insulation level to solve the problems referred to above of oily oil cooler.The present invention also may be used on the oil-water cooler.
The present invention is made up of airtight container, deep fat oil-feed flange, the fuel-displaced flange of deep fat, cold liquid feed liquor flange, cold liquid fluid flange, dividing plate, dividing plate edge, bolt, metal heat exchanger tube, pipe fin, tube side baffle plate etc.Airtight container is made by the metal material with certain mechanical strength, can bear certain internal pressure and oil stream impulsive force.There is a dividing plate at the airtight container middle part, is divided into two grease chambeies to interior: be respectively deep fat grease chamber and cold oil grease chamber.The top of described airtight container is equipped with deep fat oil-feed flange and cold liquid feed liquor flange, is communicated with deep fat grease chamber and cold oil grease chamber respectively.The bottom of airtight container is equipped with fuel-displaced flange of deep fat and cold liquid fluid flange, also is communicated with deep fat grease chamber and cold oil grease chamber respectively.Need the transformer oil deep fat of cooling to flow into the deep fat grease chamber from deep fat oil-feed flange, carry out heat exchange after, flow out through the fuel-displaced flange of deep fat again; Transformer oil cold oil as coolant flows into the cold oil grease chamber from cold liquid feed liquor flange, and logical again supercooled liquid fluid flange flows out.
