Abstract
The utility model provides a three-channel water-air intercooler used in diesel locomotives, and is characterized in that the three-channel water-air intercooler comprises a hot water channel, a lukewarm water channel and a supercharged air channel; the hot water channel is arranged at the inlet end of the supercharged air channel; the lukewarm water channel is arranged at the outlet end of the supercharged air channel; a partition board is arranged between the hot water channel and the lukewarm water channel; high-low temperature water inlet/outlet pipes and high-low temperature water inlet/outlet chambers are arranged at both ends of the hot water channel as well as both ends of the lukewarm water channel; and a cooling core body including a cooling water pipe and a radiating fin is arranged in the middle of the hot water channel as well as that of the lukewarm water channel, and the radiating fin is connected with the cooling water pipe. Compared with the prior art, the utility model has the advantages that the amount of added high-temperature system radiator groups is smaller than that of reduced low-temperature system radiator groups, so that the size of the three-channel water-air intercooler is slightly larger than that of a two-channel water-air intercooler adopting the conventional structure; however, the length of the chill room of a locomotive is reduced, the weight of the shaft of the diesel locomotive is reduced, and the integral cooling effect of the locomotive is better than that adopting the two-channel water-air intercooler.
Description
Technical field the utility model relates to a kind of internal combustion locomotive with triple channel water-aerial cooler, belongs to the heat transfer technology field.
Background technique is divided into high temperature cooling system and low-temperature cooling system in the beeliner cooling system.In the high temperature cooling system, mainly to form by diesel engine, radiator, high temperature water pump and fuel oil heat exchanger etc., the mean temperature of water is about 84 ℃ in the high temperature cooling system; In low-temperature cooling system, mainly to form by water-aerial cooler, lubricating oil heat exchanger, radiator and low temperature water pump etc., the mean temperature of water is about 65 ℃ in the low-temperature cooling system.Water-aerial cooler mainly is made up of air fin, water pipe (flat tube or pipe), main leaf, hydroecium, turnover water pipe and side guard plate etc.It is that 200 ℃ of left and right sides high temperature airs after the pressurized machine supercharging are cooled to below 80 ℃ that water in low-temperature cooling system-aerial cooler mainly acts on, to increase the air inflow of diesel engine, therefore water-aerial cooler reduces fuel consumption rate and diesel engine heat load and plays crucial effects improving diesel engine useful horsepower.
On internal combustion locomotive, it is outdoor to remove the trainman, and it is about 30% that the locomotive chilling room accounts for locomotive total length bulk, and the locomotive chilling room is mainly occupied by high-low temperature radiator, and wherein low temperature radiator accounts for about 73% of total radiator total quantity.Ask under the very harsh situation in that the internal-combustion engine axletree is important, reduce the bulk and the weight of the shared locomotive of chilling room, be very important alleviating the heavy situation at full stretch of internal-combustion engine axletree.
How to reduce locomotive chilling room bulk and weight, the way of mainly taking is to improve the heat transfer efficiency of radiator.Its main method has: the one, and the temperature conductivity of raising radiator, the i.e. heat dissipating capacity of radiator per unit volume; The 2nd, by improving the air mass flow and the air total head of cooling fan, the air velocity in the radiator is increased, but can cause the raising of cooling system auxiliary power like this; The 3rd, the temperature of the inner cooling water of raising radiator, because the heat dissipating capacity of radiator is proportional to the poor of cooling water and ambient air temperature, this situation is for the high temperature cooling system, under the condition of oil temperature and the permission of rubber seal cushion rubber is feasible, but DeGrain.For low-temperature cooling system,, the cooling effect of water-aerial cooler and lubricating oil heat exchanger is obviously reduced if improve cooling water temperature though system temperature is lower.The water that uses-aerial cooler mainly is made up of pressurized air passages and two passages of low temperature refrigeration water channel (single process or double-current journey) at present.
The summary of the invention the purpose of this utility model is exactly will pass through internal combustion locomotive water-aerial cooler structural change, the average cooling water temperature of two cooling systems of high low temperature is improved, thereby reach the purpose that reduces the cooling unit space, and triple channel water-aerial cooler is made up of pressurized air passages, high-temperature cooling water passage and low-temperature cooling water passage mainly.
This internal combustion locomotive triple channel water-aerial cooler, it is characterized in that: form by high-temperature cooling water passage, low temperature refrigeration water channel and pressurized air passages, the high-temperature cooling water passage is at the pressurized air passages entry end, and the low temperature refrigeration water channel is at the pressurized air passages outlet end.Be provided with dividing plate between high-temperature cooling water passage and the low temperature refrigeration water channel, dividing plate makes the cooling water of high temperature water system not mix each other with the cooling water of low temperature water system.High-temperature cooling water passage and low temperature refrigeration water channel two ends are equipped with high low temperature turnover water pipe and high low temperature water inlet and outlet chamber, and the centre is equipped with cooling core body.Described cooling core body is made up of cool but water pipe and coupled radiating fin.
This internal combustion locomotive of the present utility model mainly is made up of critical pieces such as cooling core body, high temperature turnover water pipe, high temperature turnover hydroecium, low temperature turnover water pipe and low temperature turnover hydroeciums with triple channel water-aerial cooler.The high-temperature cooling water passage is at the pressurized air passages entry end, and the low temperature refrigeration water channel is at the pressurized air passages outlet end.Its working principle is: when the high temperature compressed air about 200 ℃ after the pressurized machine supercharging enters water-aerial cooler, at first with the high-temperature cooling water passage in cooling water carry out heat exchange, the part heat transferred high-temperature water in the pressurized air, the temperature of high-temperature water is further enhanced, the raising of this temperature can not impact the lubricating oil of diesel engine, and the heat that high-temperature systems increases can be dissipated by the radiator of suitable increase.Pressurized air through the high-temperature water cooling carries out heat exchange with low-temperature cooling water again, finally pressurized air is cooled to specified temperature, normally brings into play with the power that guarantees diesel engine.Because the pressurized air heat that need loose is certain, be that the relations of distribution of heat dissipating capacity are Q so the heat that the low temperature water radiator will dissipate will reduce
Pressurized air=Q
High-temperature water+ Q
Low temperature waterThereby, can reduce the group number of the low temperature radiator in the chilling room.According to heat transfer principle, heat dissipating capacity formula: Q=V * ε * (tw-ta), compared with prior art, the utility model triple channel water-aerial cooler has following advantage: the group number that the high-temperature systems radiator is increased lacks than the group number that the cryogenic system radiator is reduced, though the volume of triple channel water-aerial cooler is more bigger than original structure two channel water-aerial cooler, but locomotive chilling room length is dwindled, the internal-combustion engine axletree heavily alleviates, and the overall cooling effect of locomotive is better than former two channel water-aerial cooler.
