Abstract
A kind of combined type heat exchanger tube, described heat exchanger tube is made up of inner and outer pipes, this outer tube to be connected to form by camber line by some sections of identical circular arcs and its cross sectional shape as the pipeline of plum blossom, and inner and outer tubes are by forming a kind of heat transfer medium channels between the inner surface of some sections of circular arcs of outer tube described after tight fit and the outer surface of interior pipe, and interior pipe center-aisle forms another kind of heat transfer medium channels.Because this structure inner and outer pipes is tolerance fit assembling, be compared to the vibration that existing mutually nested heat exchanger tube reduces heat exchanger to a certain extent, and be convenient to assembling.And heat exchange area also than mutually nested formula increase and strengthen heat exchange.
Description
Technical field
The utility model belongs to manufacture heat exchanger field, relates generally to a kind of combined type heat exchanger tube.
Background technology
Heat exchanger is a kind of device carrying out exchange heat for cold and hot medium, is widely used in various process industrial, as fields such as oil, chemical industry, the energy, metallurgy, Aero-Space.For a long time as the important spare part-heat exchanger tube of heat exchanger, its design shape is directly connected to the heat transfer effect of heat exchanger.The most general heat exchanger tube is used to be seamless steel pipe in prior art, except seamless steel pipe external heat exchanger mainly also adopts several intensify heat transfer pipe, seamless steel pipe because of its heat transfer area relatively little, the heat-transfer effect determining it is not very desirable, the intensify heat transfer pipe that later stage produces gradually, as finned tube, screwed pipe, spiral grooved tube etc., they are the heat-transfer effects that improve medium to a certain extent, but too increase manufacture difficulty.In addition, when two different-diameter seamless steel pipes when not supporting between two pipes, easily cause vibration in nested use.
Utility model content
The utility model provides a kind of combined type heat exchanger tube, is improved the heat transfer effect of heat exchanger by the heat exchange area increasing heat exchanger tube.
For this reason, the technical scheme that the utility model adopts is:
A kind of combined type heat exchanger tube, described heat exchanger tube is made up of inner and outer pipes, this outer tube be to be connected to form by camber line by some sections of identical circular arcs and its cross sectional shape as the pipeline of plum blossom, and inner and outer tubes are by forming a kind of heat transfer medium channels between the inner surface of some sections of circular arcs of outer tube described after tight fit and the outer surface of interior pipe, and interior pipe center-aisle forms another kind of heat transfer medium channels.
Described outer tube is made up of five sections of identical circular arcs.
The utility model provides a kind of new heat exchange tube structure form, because this structure inner and outer pipes is tolerance fit assembling, is compared to the vibration that existing mutually nested heat exchanger tube reduces heat exchanger to a certain extent, and is convenient to assembling.And heat exchange area also than mutually nested formula increase and strengthen heat exchange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of combined type heat exchanger tube is made up of inner and outer pipes, and interior pipe 2 is made for seamless steel pipe; Outer tube 1 be made up of some sections of identical circular arcs and its cross sectional shape as the pipeline of plum blossom, this outer tube by mould, adopts cold-drawn, cold rolling processing method obtains.Inner and outer pipes 1,2 assembles heat exchanger tube by tight fit, does not need other any additional process, such as the technique such as screw thread, welding.And inner and outer tubes are by forming a kind of heat transfer medium channels between the inner surface of some sections of circular arcs of outer tube described after tight fit and the outer surface of interior pipe, and interior pipe center-aisle forms another kind of heat transfer medium channels.Two media is adverse current, completes heat exchange.
Outer tube 1 can be made up of 5 sections or 6 sections or 8 sections of circular arcs, in the utility model, preferably 5 sections of circular arcs make outer tube, mainly from difform processing cost during pipe cold working, take into account simultaneously the area that different circular arc formed close with pipe runner sectional area, consider with the shell-side flow path sectional area also factor such as close the result optimized.
Claims (2)
1. a combined type heat exchanger tube, it is characterized in that: described heat exchanger tube is made up of inner and outer pipes, this outer tube to be connected to form by camber line by some sections of identical circular arcs and its cross sectional shape as the pipeline of plum blossom, and inner and outer tubes are by forming a kind of heat transfer medium channels between the inner surface of some sections of circular arcs of outer tube described after tight fit and the outer surface of interior pipe, and interior pipe center-aisle forms another kind of heat transfer medium channels.
2. a kind of combined type heat exchanger tube according to claim 1, is characterized in that: described outer tube is made up of five sections of identical circular arcs.
