Abstract
The utility model discloses a heat exchange tube internally provided with spiral spoilers. The heat exchange tube comprises a heat exchange tube wall, wherein a plurality of spiral spoilers are arranged in an inner cavity of the heat exchange tube wall and are distributed according to same angle intervals by using an axial line of the heat exchange tube as a center line; each spiral spoiler is formed by vertically crossing of four spiral sheets with completely same shapes together; the spiral spoilers have thicknesses of 0.5-2mm; the distance from the diameter of the periphery of each spiral spoiler to the inner wall of the heat exchange tube is 0.5-1mm; and the spiral spoilers are fixed on the heat exchange tube wall. The heat exchange tube has the advantages of simple structure, easiness in manufacture and high heat exchange efficiency.
Description
Technical field
The utility model relates to technical field of heat exchangers, relates in particular to a kind of heat exchanger tube of built-in spiral spoiler.
Background technology
Heat exchanger is a visual plant of realizing the cold fluid and hot fluid exchange heat in the practical applications, in fields such as electric power, chemical industry, the energy, uses extensively.Wherein shell-and-tube heat exchanger separates hot and cold two kinds of fluids through wall, passes through the exchange that unified heat exchange wall is realized heat with extratubal fluid in the pipe.In recent years, in order to satisfy the reduction production and the use cost of heat exchange requirement and maximum possible, people begin that a large amount of use costs are cheap, insert the flow-disturbing thing in the pipe of easy accessibility comes augmentation of heat transfer, comprises various informative lap-ups silk, helix, tie and rotor.The defective of prior art existence at present is: owing to receive processing technology and effect on structure, the complex structure of many flow-disturbing things, actual manufacturing is difficulty relatively, and the augmentation of heat transfer DeGrain, influences the heat exchanger effectiveness of heat exchanger tube.
Summary of the invention
The object of the invention is exactly for the complex structure of the heat exchanger tube flow-disturbing thing that solves prior art, makes difficulty, and the augmentation of heat transfer DeGrain influences the problem of the heat exchanger effectiveness of heat exchanger tube; A kind of heat exchanger tube of built-in spiral spoiler is provided; Have simple in structurely, be easy to make the advantage that heat exchanger effectiveness is high.
To achieve these goals, the present invention adopts following technical scheme:
A kind of heat exchanger tube of built-in spiral spoiler comprises the heat exchange tube wall, and the inner chamber of heat exchange tube wall is provided with a plurality of flights, and said flight is a center line with the heat exchanger tube axis, distributes at interval by equal angular.
Said flight is made up of four identical flight square crossings of shape together.
Said flight thickness is 0.5-2mm.
The peripheral diameter of said flight is 0.5-1mm apart from the inwall distance of heat exchanger tube.
Said flight is fixed on the heat exchange tube wall.Flight can be fixed on the heat exchange tube wall through welding or other modes.
Use of the utility model and operation principle: through the spiral spoiler is set tube fluid is carried out disturbance and water conservancy diversion in the pipe, make fluid in pipe, produce strong turbulent flow, break tube wall place velocity boundary layer, thus the augmentation of heat transfer effect.Built-in double helix sheet heat exchanger tube described in the utility model can suitably increase and decrease the quantity of flight according to actual requirement, and pitch also can be adjusted.The spoiler material can be the material that metal, plastics etc. can meet the practical application condition.
The beneficial effect of the utility model: simple in structure, making and use cost are low, and easy accessibility improves the coefficient of heat transfer and heat exchange efficiency, and the heat exchange effect is obvious.
Description of drawings
Fig. 1 is the structural representation of the heat exchanger tube of the built-in spiral spoiler of utility model.
Among the figure, 1-heat exchange tube wall, 2-flight, 3-fixing hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
A kind of heat exchanger tube of built-in spiral spoiler, like Fig. 1, among the figure, 1-heat exchange tube wall, the 2-flight, 3-fixing hole, the inner chamber of heat exchange tube wall 1 are provided with a plurality of flights 2, and said flight 2 is a center line with the heat exchanger tube axis, distributes at interval by equal angular; Said flight 2 is made up of four identical flight square crossings of shape together; Said flight 2 thickness are 0.5-2mm; The peripheral diameter of said flight 2 is 0.5-1mm apart from the inwall distance of heat exchange tube wall; Flight 2 is fixed on heat exchange tube wall 1 through fixing hole 3.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
