Abstract
The utility model discloses a cooler, comprising a casing (3), a cooling group (4) arranged at the inner part of the casing (3), an upper end cover (2) and a lower end cover (5) on the casing, and a water outlet pipe (1) and a water inlet pipe (6) on the end covers. The utility model is characterized in that the end part of the cooling flat pipe in the cooling group is provided with a pipe plate (4-1) and a reinforcing plate (4-3) with a multi-hole shape, a baffle (4-6) is arranged between the pipe plate and the reinforcing plate, and the connecting point of the pipe plate and the cooling flat pipe is provided with HLSnPb 58-2 Pb tin soldering material (4-4) for welding. The original mechanical performance of the base material is not damaged by the welding point of the cooler. The service life of coolers can be improved. The utility model can be used for cooling the pressurized air of the diesel engine of internal combustion locomotives.
Description
The utility model relates to a kind of cooler, is particularly useful for the cooling of medium and small diesel engine supercharging air.
In supercharged diesel engine, the pressurized air by pressurized machine extrudes need enter burning chamber of diesel engine again and burn after supercooling.At present, on diesel engine of locomotive in the used cooler, the end of the flute profile tube sheet in the cooling group and the joint of cooling flat tube adopt " material 203 " copper phosphorus antimony soldering to fix, because the fusing point of this braze is higher, in the welding process, the mother metal that is welded often descends significantly because of burning causes tensile strength, so continuous operation under the high temperature of long period, high pressure, the two ends of the cooling flat tube in the cooling group, can't stand that because of holding the internal stress that rising-heat contracting-cold causes cracks, and has a strong impact on the working life of cooler.For example, the cooler of the diesel engine of using on the at present domestic dong feng 4 internal combustion locomotive, just, make the dong feng 4 internal combustion locomotive only move tens0000 kilometers, leak with regard to producing fatigue crack in soldering place at the cooling flat tube two ends of cooler because of having adopted this braze.Therefore, shortened the working life of dong feng 4 internal combustion locomotive cooler.
The purpose of this utility model will provide a kind of novel cooler exactly, overcomes the shortcoming that cooling flat tube soldering place in the cooler is easy to generate fatigue crack, should be able to prolong the working life of dong feng 4 internal combustion locomotive cooler.
The utility model is achieved in that it comprises: housing, be installed in the cooling group in the housing, be installed in the upper and lower end cap on the housing, upper and lower end covers and is respectively equipped with outlet pipe and intake pipe, the cooling group is made up of the radiating fin that cooling flat tube and string are inserted on the cooling flat tube, is characterized in: at the end of cooling flat tube plug-in mounting flute profile tube sheet and reinforcement plate, between the end and reinforcement plate of tube sheet, be provided with dividing plate, there is the HLSnPb58-2 plumber's solder of welding the joint of tube sheet and cooling flat tube.
Described reinforcement plate is provided with several apertures.
The cooler that the utility model relates to, owing to adopted fusing point lower HLSnPb58-2 slicker solder braze and reinforcement plate, the intensity of the mother metal of welding portion is improved, thereby overcomes the shortcoming that soldering place produces fatigue crack, prolong the working life of dong feng 4 internal combustion locomotive cooler.
Be described in detail the embodiment of the cooler that the utility model relates to below in conjunction with accompanying drawing
Fig. 1. be the erection drawing of the cooler that relates to of the utility model;
Fig. 2. be the local amplification view of I portion among Fig. 1;
By Fig. 1 to Fig. 2 as can be known, the cooler that the utility model relates to, it comprises: housing 3, be installed in the cooling group 4 in the housing 3, be installed on the housing 3 on, lower end cap 2 and 5, on, be respectively equipped with outlet pipe 1 and intake pipe 6 on the lower end cap, cooling group 4 is made up of the radiating fin 4-7 that cooling flat tube 4-2 and string are inserted on the cooling flat tube, be characterized in: at the end of cooling flat tube plug-in mounting flute profile tube sheet 4-1 and reinforcement plate 4-3, be provided with dividing plate 4-6 between the end of tube sheet 4-1 and reinforcement plate 4-3, there is the HLSnPb58-2 plumber's solder 4-4 of welding the joint of tube sheet and cooling flat tube.Described reinforcement plate 4-3 is provided with several apertures 4-5.
Claims (2)
1. cooler, it comprises: housing (3), be installed in the cooling group (4) in the housing (3), be installed on the housing (3) on, lower end cap (2) and (5), on, be respectively equipped with outlet pipe (1) and intake pipe (6) on the lower end cap, cooling group (4) is made up of the radiating fin (4-7) that cooling flat tube (4-2) and string are inserted on the cooling flat tube, it is characterized in that: at the end of cooling flat tube plug-in mounting flute profile tube sheet (4-1) and reinforcement plate (4-3), be provided with dividing plate (4-6) between the end of tube sheet (4-1) and reinforcement plate (4-3), there is the HLSnPb58-2 plumber's solder (4-4) of welding the joint of tube sheet and cooling flat tube.
