Abstract
Thr utility model provides a double water to air cooler for a diesel engine of a locomotive comprises a frame; a right pipe plate and a left pipe plate for supporting a plurality of heat exchange pipes are fixed at two ends of the frame; a high-temperature water inflow cavity and a high-temperature water outflow cavity are formed on the outer side of the right pipe plate; a high-temperature water rotation cavity is formed on the outer side of the left pipe plate; the high-temperature water inflow cavity and the high-temperature water outflow cavity are communicated with the high-temperature water rotation cavity through a heat exchange pipe positioned on the front side; a low-temperature water inflow cavity and a low-temperature water outflow cavity are formed on the outer side of the left pipe plate; a low-temperature water rotation cavity is formed on the outer side of the right pipe plate; the low-temperature water inflow cavity and the low-temperature water outflow cavity are communicated with the low-temperature water rotation cavity through a heat exchange pipe positioned on the rear side; the front side of the cooler is an air inflow side; the rear side of the cooler is an air outflow side; and the air inflow side is communicated with the air outflow side through clearance among the heat exchange pipes. Through the application of the diesel engine of the cooler, the required cooling single sections for cooling a small quantity of heat quantity brought by low-temperature water is greatly reduced, and the total quantity of cooling single sections is reduced totally.
Description
Technical field
The utility model relates to a kind of diesel engine of locomotive with two waters to air cooler, is used for the cooling to the pressurized air on the locomotive.
Background technique
Along with improving constantly of railway locomotive diesel engine power, be used for the heat that the cooling water of charge air cooling takes away in air-cooler also increases thereupon, in order to obtain suitable cylinder intake temperature, needing to come charge air cooling, low temperature water to be pressurized the cooler (single-unit) that enters on the locomotive after the air heating than the water (low temperature water) that hangs down water temperature is cooled off by the air that the cooling fan rotation is blown under the operation environment.Having a narrow range of temperature and heat exchange efficiency low (especially summer) of water temperature that low temperature water is lower and ambient air.This makes that the design of locomotive is very difficult.
Summary of the invention
The purpose of this utility model provides a kind of diesel engine of locomotive of that be convenient to the cooled cooling water that certain temperature rise arranged of diesel engine of locomotive pressurized air is cooled off, simple in structure, good effect of heat exchange with two waters to air cooler, overcomes the deficiencies in the prior art.
The two waters to air cooler of diesel engine of locomotive of the present utility model, comprise framework, be fixed with right tube sheet and the left tube sheet that supports several heat exchanging tubes at the two ends of framework, it is characterized in that: the outside of right tube sheet is provided with high-temperature water and enters chamber and high-temperature water exhaust chamber, be provided with the high-temperature water turned cavities in the outside of left tube sheet, high-temperature water enters the chamber and the high-temperature water exhaust chamber is connected by heat exchanging tube and the high-temperature water turned cavities that is positioned at the front side; The outside of left side tube sheet is provided with low temperature water and enters chamber and low temperature water exhaust chamber, is provided with the low temperature water turned cavities in the outside of right tube sheet, and low temperature water enters the chamber and the low temperature water exhaust chamber is connected by heat exchanging tube and the low temperature water turned cavities that is positioned at rear side; The front side of cooler is the air approaching side, and the rear side of cooler is the air outflow side, and the air approaching side is connected by the gap between each heat exchanging tube with the air outflow side.
The two waters to air cooler of diesel engine of locomotive of the present utility model, during installation, high-temperature water enters chamber and high-temperature water exhaust chamber and is connected with high-temperature water loop on the diesel engine of locomotive, and low temperature water enters chamber and low temperature water exhaust chamber and is connected with low temperature water loop on the diesel engine of locomotive.During work, pressurized air enters from the front side of this cooler, flow out by rear side again, pressurized air is cooled in this process, because the most of heat in the pressurized air is to be taken away by high-temperature water earlier, the temperature difference of atmosphere is big under high-temperature water and the locomotive operation environment, therefore can in less locomotive cooling single-unit water temperature be dropped to suitable temperature.Atmosphere has a narrow range of temperature under low temperature water and the locomotive operation environment, the heat exchange difficulty, but because most heat has been taken away by high-temperature water, the required cooling single-unit of the small part heat that cooling is taken out of by low temperature water has just greatly reduced, add up to the total quantity that has reduced the cooling single-unit, help the general arrangement of locomotive.This cooler overall structure is simple, heat exchange efficiency is high.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a B-B cross-sectional schematic shown in Figure 1.
Embodiment
As shown in Figure 1, 2: 1 is framework, in the right-hand member bolt of framework 1 right tube sheet 6 is arranged, and in the left end bolt of framework 1 left tube sheet 13 is arranged, and is supported with several heat exchanging tubes 11 by left tube sheet 13 and right tube sheet 6, and each heat exchanging tube 11 be arranged in parallel.Be fixedly connected with right end cap 8 in the outside of right tube sheet 6, right end cap 8 inboards have high-temperature water to enter chamber 7, high-temperature water exhaust chamber 5, low temperature water turned cavities 9; Be fixedly connected with left end cap 12 in the outside of left tube sheet 13, have low temperature water to enter chamber 2, low temperature water exhaust chamber 3, high-temperature water turned cavities 4 in the inboard of left end cap 12.High-temperature water enters chamber 7 and high-temperature water exhaust chamber 5 is connected by heat exchanging tube 11 and the high-temperature water turned cavities 4 that is positioned at the front side; Low temperature water enters chamber 2 and low temperature water exhaust chamber 3 is connected by heat exchanging tube 11 and the low temperature water turned cavities 9 that is positioned at rear side.
The front side of cooler is the air approaching side, and the rear side of cooler is the air outflow side, and the air approaching side is connected by the gap between each heat exchanging tube 11 with the air outflow side.
During installation, high-temperature water enters chamber 7 and high-temperature water exhaust chamber 5 and is connected with high-temperature water loop on the diesel engine of locomotive, and low temperature water enters chamber 2 and low temperature water exhaust chamber 3 and is connected with low temperature water loop on the diesel engine of locomotive.During work, pressurized air enters by the front side of pipeline from this cooler, flow out by rear side again, pressurized air is cooled through the gap between the adjacent heat exchange tubes 11 in this process, because the most of heat in the pressurized air is to be taken away by high-temperature water earlier, the temperature difference of atmosphere is big under high-temperature water and the locomotive operation environment, therefore can in less locomotive cooling single-unit water temperature be dropped to suitable temperature.Atmosphere has a narrow range of temperature under low temperature water and the locomotive operation environment, the heat exchange difficulty, but because most heat has been taken away by high-temperature water, the required cooling single-unit of the small part heat that cooling is taken out of by low temperature water has just greatly reduced, and adds up to the total quantity that has reduced the cooling single-unit.
