Abstract
The utility model relates to a cooling device of a power system, in particular to a gearbox oil cooling bundle for ships, which mainly solves problems that a front end plate and a rear end plate of a gearbox cooler are welded with copper pipes, which is high in fixed resource consumption and low in shearing force, and further lead in welding flux pollutes environment seriously. The cooling device of a power system further solves technical problems that surfaces of copper pipes of some coolers are extruded into fins, resulting in low height of the fins and small heat transfer area due to material factors, inner surfaces are extruded by the fins into helical grooves which are easy to generate stress, and pressure resistance is relatively poor and the like. The cooling device of a power system comprises a large pipe plate (1) and a small pipe plate (2), a plurality of copper pipes (3) are connected between the large pipe plate (1) and the small pipe plate (2), the cooling device of a power system is characterized in that aluminum pipes (4) are coated on the outside of the copper pipes (3), outer surfaces of the aluminum pipes are equipped with fins (5), and a distance between the adjacent fins (5) is 1-2mm.
Description
Technical field
The utility model relates to a kind of cooling unit of power system, especially relates to a kind of to the isostructural improvement of gear-box machine oil cooling tube bundle peculiar to vessel.
Background technique
Boats and ships such as motorboat, steamer often need at the surface navigation that contains a large amount of silts, pasture and water and drift.Compound cooling is generally all adopted in the cooling of its power system, promptly utilizes the outboard water pump with in the river lake water suction ship, and realizes the cooling of power system circulating water through filter, inboard heat exchanger.Chinese patent discloses a kind of cooler that is used for gear-box (notice of authorization number: CN 2094009U), it comprises shell, is fixed on the protecgulum of shell left end, is fixed on the bonnet of shell right-hand member, filler opening, oil outlet and purge cock are arranged on the shell, water intake and water outlet are arranged on the protecgulum.Be fixed with front end-plate between protecgulum and the shell, upside-down mounting has end plate alive in the shell right-hand member, between front end-plate and end plate, be fixed with one group of parallel copper pipe, be socketed in the partition on the copper pipe, the fuse lid is housed at the outer side surface of end plate. between partition and the shell, leave the gap respectively between fuse lid and the bonnet.In the fuse lid spelter is housed, partition is 3～5mm with outer gap between bright, fuse cover and bonnet between the gap be 10～15mm.But the front end-plate of this gear-box cooler, end plate pass through welding and the consumption of copper pipe fixed resource is big, shearing force is little, and plumbous big for environment pollution in the scolder.And the copper pipe surface extrusion moulding of some cooler has fin, and because of material factors, fin height is low, and heat transfer area is little, and internal surface is subjected to fin to be squeezed into spiral chute, easily produces stress, and is withstand voltage relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of gear-box machine oil cooling tube bundle, it mainly is the front end-plate that solves existing in prior technology gear-box cooler, end plate is big by welding and the consumption of copper pipe fixed resource, shearing force is little, and plumbous problem big for environment pollution in the scolder; The copper pipe surface extrusion moulding that the utility model has also solved some cooler has fin, and because of material factors, fin height is low, and heat transfer area is little, and internal surface is subjected to fin to be squeezed into spiral chute, easily produces stress, the technical problem of withstand voltage relatively poor grade.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Gear-box machine oil cooling tube bundle of the present utility model, comprise large tubesheet and little tube sheet, be connected with some copper pipes between large tubesheet and the little tube sheet, it is characterized in that described copper pipe outer cover is connected to aluminum pipe, the outer surface of aluminum pipe is provided with fin, and the spacing h between adjacent fins is 1～2mm.Aluminum pipe can be that rustproof aluminum alloy is made, and it can be squeezed into the higher fin of spacing, increases heat diffusion area.Sturdy between aluminum pipe and the copper pipe, avoid the space and produce thermal resistance.Copper pipe can be 50～80 of be arrangeding in parallel, and it is arranged in cylindric.
As preferably, the aluminum pipe end is stretched out at the two ends of described copper pipe, and is plugged on respectively on large tubesheet and the little tube sheet.The mouth of pipe at copper pipe two ends is taked expansion tube process, and is affixed with large tubesheet, little tube sheet, improved compressive strength like this, free from environmental pollution again.
As preferably, be provided with deflection plate between described large tubesheet and the little tube sheet, the vertical cross-under of aluminum pipe is on deflection plate.A plurality of deflection plates form " S " type passage, and it can guide oil circuit.
As preferably, the wall thickness d of described copper pipe is 0.8～1.2mm.Wall thickness d the best of copper pipe can be 1mm.
As preferably, described little tube sheet also is connected with sleeve pipe and spacing bar between large tubesheet and the little tube sheet.Casing pipe sleeve is at the spacing rod outer surface, and it can determine the distance between large tubesheet and the little tube sheet, and can determine the spacing between the deflection plate.
Therefore, the front end-plate, the end plate that the utlity model has the gear-box cooling tube bundle pass through to be connected with heat dissipating pipe by expansion tube process, avoided plumbous in the scolder environment is produced pollution characteristics; The utility model also has in the copper pipe outer cover and is connected to aluminum pipe, and the aluminum pipe outer surface is provided with fin, thereby makes the fin height height, and heat transfer area is big, is difficult for producing stress, withstand voltage better, characteristics such as simple and reasonable for structure.
