Description
Technical field
The present invention relates to the device feature of a kind of general heat exchange, specifically the finned tube of the heat abstractor of a kind of heat exchange.
Background technology
In gear-box, lubricating oil is when dispelling the heat by finned tubular radiator, owing to operative gear case lubricating oil caloric value is too high, existing gear box lubricating oil cools down at heat radiator fin Bottomhole pressure, only dispels the heat with removing the fin on finned tube by finned tube, and in cooling runs, heat transfer effect is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of finned tube strengthening lubricating oil radiating efficiency, and the technical program is by changing the structure of finned tube, effective improving radiating effect.
For solving above-mentioned technical problem, a kind of finned tube strengthening lubricating oil radiating efficiency of the present invention, including the finned tube with fin, it is provided with in finned tube in fin and manages, be additionally provided with in pipe in fin in one and manage；The length of interior pipe is more than the length of pipe in fin, and the two of interior pipe ends are exposed from pipe in fin；Two ends of interior pipe are provided with outlet and water inlet；Gap between inner tube outer surface and finned tube inner surface forms the Oil Guide passage of lubricating oil；
As the further improvement to the technical program, interior tube hub is provided with a zinc bar, and zinc bar fixes the one end being bolted to interior pipe by zinc bar, and zinc bar is fixing, and bolt is airtight with interior pipe is connected, the gap composition conduit pipe between zinc bar and interior pipe.
As the further improvement to the technical program, in fin, pipe can be connected with pipe in other fin by connecting plate and bumped head, forms the Oil Guide passage of series connection；Conduit pipe is connected with other conduit pipe by string water elbow, forms the conduit pipe of series connection.Multi-disc finned tube can be chained together use by bumped head and connecting plate and string water elbow.
A kind of finned tube strengthening lubricating oil radiating efficiency of the technical program, manages by being provided with in fin in finned tube, is additionally provided with in one and manages in fin in pipe；The length of interior pipe is more than the length of pipe in fin, and two ends of interior pipe are provided with outlet and water inlet.So, while the gap between inner tube outer surface and finned tube inner surface forms the Oil Guide passage of lubricating oil, the space in interior pipe is split into a conduit pipe, increases current to the cooling of lubricating oil in Oil Guide passage, is effectively improved cooling effect.
Reynolds is through great many of experiments, and adopts dimensional analysis and principle of similitude method, have found fluid and the critical flow velocity of laminar flow or turbulent flow occurs: the fluidised form Re < 2000 of circle tube fluid is laminar flow, or turbulent flow；Re>4000 is turbulent flow: 2000<Re<4000 or for laminar flow, or turbulent flow.For in non-circular section runner fluid flow state, Re<500 is laminar flow, Re>500 be turbulent.Zinc bar is fixed on one end of interior pipe by the fixing bolt of zinc bar, and zinc bar is fixing, and bolt is airtight with interior pipe is connected, the gap composition conduit pipe between zinc bar and interior pipe.Can making lubricating oil when by the gap of Oil Guide passage, change original flow regime, can effectively form Turbulence Flow, the fluid particle that lubricating oil is formed, in motor process, intermixed, interts, and effectively promotes heat transfer effect.While promoting cooling effect, cooling water when quitting work at gear-box, can also can be played antirust, anti-scaling action by zinc bar.
Cooling water circulating device contrast test tables of data is increased as follows in heat radiator fin pipe:
Comparison of test results: the more former common tube of the present invention adds interior pipe radiating efficiency and 1. improves 113.6% when natural cooling；2. improve 100.8% when additional fan coolling.

Detailed description of the invention
The present invention is further detailed explanation for connection with figures below.
Engage Fig. 1, Fig. 2, Fig. 3 it can be seen that a kind of finned tube 5 strengthening lubricating oil radiating efficiency of the present invention, including the finned tube 5 with fin, in finned tube 5, be provided with in fin pipe 4, in fin, in pipe 4, be additionally provided with in one pipe 2；The length of interior pipe 2 is more than the length of pipe in fin 4, and the two of interior pipe 2 ends are exposed from pipe in fin 4；Two ends of interior pipe 2 are provided with outlet and water inlet；Gap between interior pipe 2 outer surface and finned tube 5 inner surface forms the Oil Guide passage 9 of lubricating oil.
Interior pipe 2 center is provided with a zinc bar 3, and zinc bar 3 is fixed on one end of interior pipe 2 by the fixing bolt 1 of zinc bar, and zinc bar is fixing, and bolt 1 is airtight with interior pipe 2 is connected, the gap composition conduit pipe 10 between zinc bar 3 and interior pipe 2.
In fin, pipe 4 can be connected with pipe in other fin 4 by connecting plate 6 and bumped head 7, forms the Oil Guide passage 9 of series connection；Conduit pipe 10 is connected with other conduit pipe 10 by string water elbow 8, forms the conduit pipe 10 of series connection.
A kind of finned tube 5 strengthening lubricating oil radiating efficiency of this practicality honor, when the lubricating oil needing heat radiation passes through Oil Guide passage 9, having the stream water-heat exchange for heat dissipation in conduit pipe 10 in it, its outer finned tube 5 having with fin dispels the heat with air heat exchange, and radiating effect is better.
Inventive technique scheme is not done any pro forma restriction by above detailed description of the invention; if without departing within the scope of technical solution of the present invention; the equivalence enforcement utilizing the done technically local of technical solution of the present invention disclosure to change or modify, all still falls within the scope of protection of the invention.
