The utility model provides a present shell -and -tube oil cooler core problem that adopts the gas brazing to exist, have the qualified rate of product welding height, technology convenient operation, safe and reliable's advantage.
Description
Technical field
This utility model relates to electromotor stainless steel shell-and-tube oil cooler, and specifically cartridge type engine oil cooler core body adopts a kind of structure of stainless steel material vacuum brazing.
Background technology
At present, the tube sheet of electromotor cartridge type engine oil cooler core body and flange are by forging the molding that is made into one, and part concordance is poor, all parts of core body adopt red copper material, being welded by torch brazing, and in gas brazing process, the factors such as gas flow is by management and control, welding quality is all that the operating experience by employee ensures, this results in, and the disposable solder yield of product is low, and homogeneity of product is poor, and staff labor intensity is also big, production efficiency is low, and production cost remains high.And after gas brazing, product surface has much oxide skin, welding slag etc., causes that product cleannes are overproof.
Summary of the invention
Goal of the invention of the present utility model is the above-mentioned deficiency in order to overcome prior art, and provides the stainless steel shell-and-tube oil cooler that a kind of Product jointing qualification rate is high, technological operation is convenient, safe and reliable.
The technical solution of the utility model is: include tubular shell, shell one end is provided with flange, flange has multiple installing hole one, the housing other end is sealedly connected with tube sheet assembly, tube sheet assembly is made up of lower perforated plate, upper perforated plate, lower perforated plate has the installing hole two corresponding with each installing hole one, the cooling tube group one end being placed in housing is plugged in installing hole one, the cooling tube group other end is plugged in installing hole two, being connected in the middle part of the deflector of inner walls and be provided with and the installing hole three coordinating assembling in the middle part of cooling tube group, flange, deflector, lower perforated plate surface are provided with copper plate.
Cooling tube group includes multiple cooling tube.
Flange, deflector, tube sheet assembly, cooling tube are made of stainless steel.
Deflector is interspersed and is connected in inner walls.
Staggered being equally spaced of deflector is connected in inner walls.
Upper perforated plate outer wall has more than one cannelure, and each cannelure place is equipped with the sealing ring being tightly connected with inner walls.
Flange is connected with water inlet pipe lid through bolt.
The all parts of cartridge type engine oil cooler core body all adopt stainless steel, tube sheet on cartridge type engine oil cooler core body is split into upper perforated plate and lower perforated plate, lower perforated plate adopts die drawn punching, only need to carry out copper plating treatment on the lower perforated plate surface having solder side, to meet vacuum brazing needs, with red copper for solder, put into and vacuum brazing furnace carries out vacuum brazing, make soldering Product jointing qualification rate out higher, weld seam is full, product surface quality, cleannes are good, reduce staff labor intensity.Meanwhile, solderless junction on upper perforated plate, upper perforated plate surface does not need copper plating treatment, adopts assembled tube sheet can effectively save copper-plated area.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structure chart of tube sheet assembly.
Detailed description of the invention
Fig. 1, in 2, the part of stainless steel shell-and-tube oil cooler core body of the present utility model: 1-flange, 2-deflector, 4-cooling tube, 5-lower perforated plate, 7-upper perforated plate all adopts 304 stainless steels, wherein flange 1, and deflector 2 and lower perforated plate 5 surface carry out copper plating treatment.First lower perforated plate 5 and upper perforated plate 7 are assembled into tube sheet assembly, lower perforated plate 5, flange 1, deflector 2 all there is cooling tube installing hole, cooling tube 4 is penetrated one by one in the installing hole of flange 1, deflector 2, tube sheet assembly, it is assembled into core assembly, fix again through fixture, putting into and carry out vacuum brazing in vacuum brazing furnace, soldering becomes oil cooler core body.There is upper perforated plate 7 oil cooler core body one end, and upper perforated plate has 2 O type grooves, and there is annular seal space tubular shell (abbreviation housing) 3 sides, is sealed by O tube sheet side and housing 3；Housing 3 opposite side has four bolts, the oil cooler core body other end has flange 4, four installing holes corresponding with four bolts of housing are had above flange 4, water inlet pipe lid also has four installing holes corresponding with four bolts of housing, by these four bolts, flange 1 is fixed between water inlet pipe lid and housing 3.
In Fig. 3, tube sheet assembly is made up of lower perforated plate 5, upper perforated plate 7, and lower perforated plate 5 has the installing hole two corresponding with each installing hole one, and upper perforated plate 7 outer wall has two cannelures 8, and second ring groove place is equipped with the sealing ring being connected with tubular shell inner wall sealing.
It is understood that above-described embodiment is simply to explanation of the present utility model, rather than to restriction of the present utility model, any without departing from the utility model creation in this utility model spirit, each fall within protection domain of the present utility model.
