Abstract
The utility model relates to a snakelike spring turbulent device which is a novel internally heating inner insertion body of a reinforced pipe, composed of a core wire and one or a plurality of springs. The utility model is characterized in that the springs form curved snake shapes. When more than two springs are used, in order to prevent the springs from being stacked, the springs have different spiral directions or the springs with different spiral directions are mutually sheathed. The snakelike spring turbulent device has the advantages of good reinforced heating effect, easy fabrication, convenient installation and disassembly, low price, etc., and is an ideal inner insertion body.
Description
The utility model belongs to a kind of interpolation thing of giving heat in the enhanced tube.
With the heat-transfer pipe is in the heat transmission equipment of heat exchange element, less when the heat transfer coefficient of tube side, when becoming the restraining factors of heat transfer, should manage to give in the enhanced tube heat.Because the interpolation thing has and need not pipe is carried out special processing, both has been applicable to that the new system heat transmission equipment also is applicable to the transformation of the heat transmission equipment that has moved, has smail investments and quick rerurn, be easy to advantages such as assembling maintenance.In the last thirty years, to having carried out a large amount of research and developments in the enhanced tube interpolation thing of heat, many achievements have been obtained both at home and abroad.
Single helix (also claiming spring) is the interpolation thing that uses the earliest.It has advantages such as processing is simple, installation is easy.But owing to it has reduced the flow velocity at nearly wall place in the pipe, the inhomogeneities of speed in the enlarged tube, the thickness of increase boundary film, in pitch and relative altitude one timing relatively, along with the increase of fluid Reynolds number, heat transfer coefficient only has increase slightly in the pipe, and sharply increase falls in the pressure of fluid.But fried dough twist sheet, static mixer and flight are all given heat in the enhanced tube, but owing to strengthen and just rely on turbulent flow to cause what eddy current effect realized, so that their pressure falls is very big.Porous body lap-ups silk is because dispersion effect promotes the little local crossing current of fluid to give heat in the enhanced tube.But because it is more with silk, coiling complexity particularly fluid lacks the zone crossing current.And we know that making the zone crossing current from reinforcement dynamics fluid is greater than little local crossing current.
The purpose of this utility model aims to provide the little local crossing current of fluid that a kind of existing because dispersion effect causes, has again because interpolation thing---the snakelike spring turbulator of the fluid mass crossing current that turbulent flow causes.It is made up of core silk and one or more spring.It is characterized in that spring all is the snakelike of bending, when using more than two many springs, folded for preventing that edge takes place between spring, spring should have different rotation directions, or adopt the different spring of rotation direction to be nested, the core silk is convenient to install or is extracted out and insert thing, and when using hard thicker material to make the core silk, snakelike spring can curl on it; When using softer thinner material to make the core silk, the core silk with snakelike spring turn round mutually around.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is by hard thick core silk 2 and the snakelike spring turbulator that spring 3 is formed.It inserts the inwall of heat-transfer pipe 1.Contact for point on snakelike as seen from the figure spring and the inside pipe wall, when passing spring body, fluid under the effect of spring line, produces dispersion effect, and in by the formed spiral of snakelike spring road, produce the zone crossing current, for strengthening dispersion effect, can form by the snakelike spring that two diameters do not wait as Fig. 2.
Fig. 3 is that soft and thin core silk 2 two piece springs different with rotation direction tussle mutually and form.Fig. 4 is an identical spring and less being placed in the different big spring of rotation direction of diameter of three diameters that soft and thin core silk 2 is different with rotation direction, and they and core silk are woven together forms again.
This snakelike spring turbulator only a bit contacts with inside pipe wall, produces the line contact unlike single helix, and boundary film is thickened.This existing fried dough twist sheet, static mixer and flight etc. have the function of promotion zone crossing current, porous body lap-ups line are arranged by the little local function of flowing over that dispersion effect causes again, have advantages such as easy to manufacture, that the installation demolition is convenient, cheap in addition.It is a kind of desirable interpolation thing.
Claims (3)
1. a snakelike spring turbulator is made up of core silk and one or more spring, it is characterized in that spring all is the snakelike of bending.
2. a snakelike spring turbulator as claimed in claim 1 is characterized in that having different rotation directions between spring.
3. one kind as claim 1 and the described snakelike spring turbulator of claim 2, is characterised in that altogether to adopt to curl, tussle and way such as braiding, and spring and core silk are formed a whole.
