Description
Technical field
The utility model relates to heat exchanger, refers in particular to a kind of novel charge air cooler and thermofin.
Background technology
In chemical industry and oil refining enterprise production operation, need a large amount of compressed air sources.Utilize centrifugal compressor that air is compressed.But, the rising that air also can bring self temperature in the compressed while, this is disadvantageous in chemical industry and oil refining production operation.In order to reduce the Compressed Gas temperature, connect an aerial cooler in the back of centrifugal compressor, i.e. the said charge air cooler of this paper makes the temperature of compressed air drop to the temperature range of permission by it.A kind of charge air cooler was once arranged, and its core body adopts the tube side type of cooling, and cooling fins promptly is installed in tubulation, and air passes through from pipe.The shortcoming of this structure is that complex structure keeps in repair trouble, when keeping in repair if desired, must remove all pipelines of inside and outside connection by folding, overall structure is rolled over to loose could implement maintenance.Because tubulation and fin all adopt copper material, have consumed national narrow resources, have also improved equipment cost
Summary of the invention
The purpose of this utility model is improved, is innovated at the shortcoming and defect in the background technology, and a kind of novel charge air cooler and thermofin are provided.
The technical solution of the utility model is: construct a kind of charge air cooler that comprises housing, cooling water pipe, fin, branch water cover plate, form core body by cooling water pipe, fin, end plate and cover plate; Divide the water cover plate to be located at housing and core body one end, be used for cooling water is introduced in the cooling water pipe of core body, be drilled with the pore of arranging by designing requirement on the described thermofin, cooling water pipe all passes pore one by one, and thermofin distance in accordance with regulations is installed on outside the cooling water pipe with layered laminate; The end plate at fin and cooling water pipe and cooling water pipe two ends and fin cover plate up and down is an overall structure, by shell flange with its integral installation in housing.
The utility model thoroughly innovation and brand-new design the charge air cooler assembly, researched and developed supporting with it charge air cooler core body and the efficient aluminium matter of enhanced type thermofin synchronously, thereby the problem that makes in the background technology to be mentioned is solved.Particularly, when charge air cooler need overhaul, need only dismantle branch water cover plate, extract the charge air cooler core body out and can implement maintenance, simplify and made things convenient for operation greatly, reduce workload, the loss of significance of especially having avoided equipment to disintegrate and cause.The result that the utility model is tried out on the large centrifugal compressor, the inter-stage outlet temperature of unit has descended 5-8 ℃ than former machine, and compression end of a period pressure has improved 0.15MPa, and the raising rate has reached 29.4%.

The specific embodiment
By Fig. 1 to 4 as can be known, the utility model comprises housing 1, cooling water pipe 4, fin 5, divides water cover plate 3; Form core body 2 by cooling water pipe 4, fin 5, end plate 23 and cover plate 21; Divide water cover plate 3 to be located at housing 1 and core body 2 one ends, be used for cooling water is introduced in the cooling water pipe 4 of core body 2, be drilled with the pore of arranging by designing requirement 51 on the described thermofin 5, cooling water pipe 4 all passes pore 51 one by one, and thermofin 5 distance in accordance with regulations is installed on outside the cooling water pipe 4 with layered laminate; Fin 5 is an overall structure with the end plate 23 and the fin cover plate 21 up and down at cooling water pipe 4 and cooling water pipe 4 two ends, by shell flange with its integral installation in housing 1.
Be provided with horizontal concavo-convex rib 52 and vertical concavo-convex rib 53 around the pore 51 of fin 5 described in the utility model, be used to strengthen the intensity and the augmentation of heat transfer of fin 5; Described thermofin 5 is the aluminum metal structure.The upper and lower surface of the described core body of being made up of cooling water pipe 4 and fin 52 is provided with seal cover board 21, is used to make after core body 2 is contained in the housing 1, and high temperature compressed gas arrives opposite side by the gap of a side by fin 5, implements cooling and also discharges housing 1.Described housing 1 also comprises air inlet 11, exhaust outlet 12.Housing 1 is provided with two flanges 13 and 14, and flange 13 connects and divides water cover plate 3, and flange 14 connects compressor.Flange-interface 14 centers also are provided with a compressor intake interface 15.The outer face of described minute water cover plate 3 is provided with cooling water inlet 31 and coolant outlet 32, divides the big end plate 23 of water cover plate 3 connection core bodys 2, cooling water is introduced the cooling water pipe 4 of core body 2.
Process structure of the present utility model is: the utility model charge air cooler assembly is made up of three big part cases 1, charge air cooler core body 2, branch water cover plate 3, core body 2 is in inner orientation propelling, the location and installation of housing 1, by 20 fastening bolts the three is reinforced and to be integral, and air and cooling water strictness are separated, and guarantee sealing with two " O " shape sealing rings 18.Charge air cooler assembly end face A is connected with main frame, is tightened by 20 bolts.Add graphite gasket 19 between end face and the main frame joint face, in order to sealing and heat insulation.Cooling water enters branch water cover plate by water inlet, and is divided into the flow process of design code by minute water cover plate, gets back to circulation through outlet pipe then.Charge air cooler core body 2 and the thermofin 5 that is adopted thereof all are the present invention's new structure and products of research and development synchronously.
