Description
Technical field
The present invention relates to a kind of oil cooler.
Background technology
Oil cooler is a kind of visual plant commonly used in the fields such as power plant, ship, be widely used in power, nuclear energy,
The industrial circles such as chemical industry, refrigeration, machinery.Its task is cooling lubricating oil to proper temperature, to ensure the friction portion of main and auxiliary equipment
Part can normally be lubricated and be cooled down, without triggering accident because oil temperature is too high.
Because lubricating oil is by after these friction means, oil temperature typically has 20~30 DEG C of rising, even more high.Temperature
Raise, oil body reduction, now, lubricating oil cannot well meet lubricating requirement and cooling is required.If this kind of
In the case of lubricating oil directly gone again if lubrication friction part without supercooling, the lighter threaten equipment safety and stability fortune
OK, severe one triggering safety system action, or even damage friction means（Such as bearing）, cause interruption of service.
Current oil cooler peculiar to vessel typically uses light pipe or panel cooler, light pipe cooler to there is heat exchange efficiency
The huge shortcoming of low, complex structure, equipment volume, panel cooler efficiency improves, but because flow channel space is narrow and small, stream
Dynamic resistance resistance is big, and complex structure is high to power demand.This requires to carry out rational design studies, produces high-efficiency compact
Oil cooler, be allowed to the fund of saving, energy saving reduces metal consumption and the space shared by equipment.
In recent decades, various industry are developed rapidly, and the engineering equipment such as rocket, Aeronautics and Astronautics, navigation is because of space and power
It is limited, with greater need for using size is small, light weight compact heat exchanger.Especially in atomic marine plant, heat transmission equipment is accounted for
According to power set gross weight and size more than half, in the limited space in naval vessel, can be real using heat transfer enhancement technology
The miniaturization of existing heat transmission equipment, so as to can not only improve the working environment of ship's staff, can also improve equipment and install and tie up
The condition repaiied.
Used as novel heat exchange element, it is processed overall three-dimensional Needle fin tube using special method, by specific purpose tool
Pin wing is directly processed on plain tube, tiny and intensive pin wing spirally bends and with certain joint slope in base tube
On, pipe heat-transfer area extends 2~5 times, can destroy or thinning boundary layer, and effect is used to the less occasion of pipe outside heat transfer coefficient
It is high viscosity oil that fruit preferably, such as is managed outer, so as to reach the purpose of enhanced heat exchange.
The content of the invention
It is an object of the invention to provide a kind of longitudinal-flow visual oil cooler of full Needle fin tube, the cooler is all by entirety
On the one hand Needle fin tube so improves the compactedness of oil cooler as heat exchanger tube, improves heat transfer property, on the other hand makes
The processing and installation for obtaining heat exchanger become more to facilitate, and make cooler size more compact, and whole course visible oil flow is emotionally
Condition.
The purpose of the present invention is achieved through the following technical solutions：
A kind of visual oil cooler of full Needle fin tube of longitudinal-flow, including Needle fin tube beam, upper lubricating oil spoiler, lower lubricating oil spoiler,
Upper perforated plate, lower perforated plate, upper cover, low head, housing, upper perforated plate and lower perforated plate are separately fixed at two end faces up and down of housing
On, upper perforated plate outside is fixed with upper cover, and lower perforated plate outside is fixed with low head, is provided between upper perforated plate and lower perforated plate some
Row's Integral pin-fin tube beam, is provided with lubricating oil spoiler and lower lubricating oil spoiler on Integral pin-fin tube beam, shell side is opened up on housing
Import and shell-side outlet, upper cover and low head offer tube side import and tube side outlet, shell side import side body second row pin
The visual groove of internal greasy dirt is provided with finned tube, transparent plexiglass plate is covered on the internal visual groove of greasy dirt.
The invention has the advantages that：
1st, whole course visible, can be visually seen lubricating oil flowing live, lubricating oil color and pollution level, and sees and be easiest to fouling portion
Position scaling degree, determines scavenging period and gap periods.
2nd, heat exchange efficiency is increased substantially, reduces cooler volume, the limited occasion of especially suitable arrangement space.
3rd, vertical manifold formula is taken, flow resistance and tube bank itself vibration can be reduced, played and increase the service life and energy-conservation
Purpose.
4th, simple for structure, processing installs simple, using, it is easy to maintenance.
5th, space flexible arrangement, can flexibly change cooler height and stringing radical, it is also possible to will according to use condition
Housing cross-sectional is changed to the other shapes such as circle, rectangle, ellipse by square, will not increase processing, installation difficulty, and using changing
The thermal efficiency does not have larger change.
