Abstract

The utility model relates to an intercooler for air compressors. A casing is formed by welding an upper flange, a lower flange, a front flange, back flange, a left closing plate and a right closing plate. A core group positioned in the casing is composed of a plurality of nest plate tube groups, the front tube plate and the back tube plate of the two ends of the nest plate tube group, a front tube plate, a back tube plate, a front water cover and a back water cover at both ends of nest plate tubes. A back sealing head is in thread connection with the casing. When the utility model is cleaned, only the back sealing head and the front and back water covers are opened without withdrawing the core group. The utility model is time-saving and labor-saving, and can effectively avoid the damage in the process of disassembling and assembling the core group. Because the nest plate tube groups are used, the utility model has the advantages of reducing the power consumption of air compressors, reducing the size about 1/4 under the equal working condition and saving lots of steel materials, copper materials and capitals. The utility model has good cooling effect.

Description

Intercooler for air compressor

The utility model relates to a kind of heat-exchange apparatus, particularly a kind ofly is suitable for using in the air compressor, and water and air carry out the intercooler of heat exchange.

Usually, the sheet pipe drawer type of the scratching intercooler that uses in the air compressor, roll sheet pipe drawer type intercooler, scratch the inclined to one side cast intercooler of sheet, its version is hexahedron, a housing left side, shut right and back, the fuse group that is positioned at housing is connected with the front housing by flange, and logical from top to bottom cooled air, this class cooler is when maintenance, all need the fuse group is extracted out from housing, be put on the shelf of a special use and clean, because this intercooler is placed on below the air compressor, and apart from ground two meters height, can't utilize mechanical hoisting equipment, and this equipment volume is big, deal is heavy again, and fuse weight is more than 1 ton, once needs waste time and energy in 2-3 days so dismounting is cleaned.And the tube sheet of expanded joint and pipe in disassembly process easily take off owing to vibrate and split, cause air water to mix and destruction pneumatics unit, in addition, the sheet cast is scratched sheet and pipe binding site gap is big owing to scratching again, rolling the sheet cast, to be rolled sheet limitation in height heat exchange area little, pipe is arranged and is dredged, so its heat exchange effect is also relatively poor.

The purpose of this utility model is to provide a kind of easy cleaning, and good effect of heat exchange is little in same condition of work situation lower volume, lightweight air compressor intercooler.

For achieving the above object, the utility model is by last, down, before, four flanges in back and a left side, right two shroudings connect and compose six face-piece bodies, the cooler core group that is positioned at housing is by the 4--8 journey, every journey 5--10 nest plate pipe group, before the nest plate pipe group two ends, back tube sheet and play the sealing and the helical pitch effect before, back water cover constitutes, sheet will be scratched in the prior art, roll sheet and be replaced by nest plate pipe group, nest plate pipe group is made of nine copper tubes and rectangle copper sheet, copper sheet is provided with three row's cross arrangements hole identical with number of tubes, and expanded joint is on pipe, adopt this structure to make to be issued to volume in equal condition of work little, lightweight purpose.Rear head is connected on the housing by bolt, and the fuse group also is to be connected with preceding square flange by bolt, thereby reaches convenient purpose of cleaning.

In conjunction with the accompanying drawings the utility model is elaborated below by embodiment:

Fig. 1 is the utility model structural front view.

Fig. 2 is the utility model structure side view.

Fig. 3 is the utility model nest plate pipe group structural front view.

Fig. 4 is the utility model nest plate pipe group structure side view.

The utility model is positioned at the fuse group (1) of housing and rear head (3) etc. by housing (2) to be formed, and housing (2) is by upper flange (6), square flange (9), preceding square flange (7), back square flange (5) and left and right shrouding (11), (10) are welded down.The nest plate Guan Zuzhong copper sheet (1-1-2) that fuse group (1) adopts is a rectangle structure, is provided with the hole of three row's cross arrangements above, and the copper sheet expanded joint is on nine copper tubes (1-1-1).Thereby constitute one group of nest plate pipe group (1-1), nest plate Guan Zuwei 6 journeys in the fuse group (1), 5 groups of every journeys constitute rectangular structure.Before, back tube sheet (1-4), (1-5) be provided with and 30 corresponding holes of nest plate Guan Zuzhong copper sheet, and expanded joint plays a part at the two ends of nest plate pipe group to connect and supporting nest plate pipe group, before, back water cover (1-2), (1-3) by the flange (8) on the water cover before and after being welded on and (4) by being bolted to front and back tube sheet (1-4), (1-5), be welded with flange (5) on the rear head (3), rear head (3) by flange (5) by being bolted to the housing back, for being convenient for changing new fuse group, three rollers (12) are installed on fuse group (1), (13), (14) and be supported on track (15), (16) on.

The utility model is mounted in one section in air compressor, exits such as two sections, several sections compressions should be provided with several fuse groups, when the utility model carries out heat exchange, hot-air is by the top cooler that enters in the air compressor, contact with the fuse group, and water enters tube side by the preceding water cover bottom of fuse group, flow out and air formation perpendicular flow by preceding water cover top outlet pipe, air is cooled down, can be during cleaning respectively with rear head (3), back water cover (1-3), bolt on the preceding water cover (1-2) unclamps, take off rear head (3), back water cover (1-3), tube sheet (1-4) before and after preceding water cover (1-2) makes, (1-5) and pore be exposed to the outside, pipe is cleaned.

The utility model is owing to adopted nest plate pipe group, so, not only good cooling results promptly by about 40 ℃ of original cooler outlet air themperatures, is reduced to about 30 ℃, and reduced the power consumption of compressor, cause tolerance to increase 5-10%, under equal condition of work, can make volume-diminished nearly 1/4, save about 55 kilograms of red coppers, nearly 750 kilograms of steel.Can clean owing to not extracting the fuse group out again,, be easy to clean so not only clean conveniently, time saving and energy saving, make whole cleaning process only need 4-5 hour, but also can effectively avoid the damage that causes in the fuse assembly and disassembly process, thereby also reached considerable economic.
