Abstract
A spiral flat-fin oil cooler belongs to the technical field of design and manufacturing of oil cooer and is used for cooling hydraulic oil and lubricating oil. It comprises housing and heat exchange fin disposed inside the housing. The heat exchange fin is spiral and flab and is entwined to allow the cooled hydraulic oil in roller flow state within the fin, increase the turbulence and reduce laminar layer, so that the oil heat is rapidly absorbed by the cooling water. The utility model overcomes the problem of lower heat transfer efficiency due to irrational fin structure, which may exist in the conventional plain fin oil cooler, corrugated fin oil cooler and screwed fin oil cooler.
Description
Technical field
This reality has the design and the manufacturing technology field of novel genus oil cooler.
Background technology
At present in production reality to the cooling device of hydraulic oil or lubricating oil, all be to adopt the shell-and-tube oil cooler, be divided into light pipe oil cooler, screwed pipe oil cooler and bellows oil cooler according to the difference of heat exchanger tube shape and structure.But the oil cooler of these different tubular types is owing to shape and structural reason, and its heat exchange effect is all undesirable.The effect that wants to reach required just must strengthen cooling water flow.Also do not use in practice at present with the utility model like products.
Summary of the invention
The purpose of this utility model provides a kind of spiral flat tube formula oil cooler, increases intraductal heat exchange oil turbulent extent.To solve the unfavorable problem of heat exchange effect that existing equipment exists.
Structure of the present utility model is as shown in drawings: constitute by cooler casing with as the spiral flat tube of heat exchange oil pipe.At the housing two ends tube sheet is arranged.Have spiral flat tube between the tube sheet, respectively there is an end socket in the tube sheet outside in two ends.The outlet of hydraulic oil import and hydraulic oil is arranged on the end socket.Housing top has cooling water inlet and coolant outlet.Using method of the present utility model is identical with existing product.Cooling water flows to outlet from import, and hydraulic oil flows to outlet from import.But because the heat exchange oil pipe of this product is a spiral flat tube, spiral flat tube is twisted shape.Will make hydraulic oil increase oily turbulent extent when the spiral flat tube like this, make that whelk is rotating in the pipe flows, the attenuated layer fluid layer makes institute's heat content water that in time is cooled apace absorb, and has improved the heat exchange effect.The utility model design is ingenious, has only changed the shape of hydraulic oil heat exchanger tube, both can improve the heat exchange effect, saves electric energy again.It is a kind of comparatively desirable oil cooler.

The specific embodiment
Structure of the present utility model is as shown in drawings: be made of housing (9) and its inner heat exchange oil pipe.Have tube sheet (7) at the two ends of housing, tube sheet is fixed on the housing two ends by the mode of welding.Have plurality of tube holes on the tube sheet.Heat exchange oil pipe between two tube sheets is spiral flat tube (8), and spiral flat tube is twisted shape.The two ends hydraulic oil of spiral flat tube is imported and exported to circular.Insert in the heat exchange pore at the two ends of spiral flat tube, fixes with the expanded joint method.Have end socket (7) in the outside of two tube sheets.Have sealing gasket (6) between end socket and the tube sheet.Housing connects fixing with end socket by coupling bolt mutually.On the end socket of left side, have hydraulic oil import (1), on the end socket of right side, have hydraulic oil outlet (4).Have coolant outlet (2) and cooling water inlet (3) on housing top.
Claims (1)
- The spiral flat tube oil cooler is made of housing (9) and its inner heat exchange oil pipe, it is characterized in that said heat exchange oil pipe is spiral flat tube (8), and spiral flat tube is twisted shape.
