Abstract
The utility model discloses an inner groove structure high-efficiency heat exchanging pipe with high heat exchanging efficiency. The utility model is characterized in that rectilinear or rectilinear figure grooves are arranged on the inner wall of the pipe in the direction of the axis; the shape of each of the grooves is a rectangle, a square or a sawtooth shape. The utility model has the advantage of simple structure. The hydromechanical properties of a heat exchanging medium are improved by the improvement of the inner structure of the heat exchanging pipe so that the utility model realizes the optimum assembly. The utility model can be used for various heat exchangers which are used in the industries of chemical industry, petroleum, metallurgy, medicine, alkali manufacture, light industry, electric power, etc.
Description
Technical field
The utility model relates to a kind of heat exchanger tube of using in solution-air, liquid-gas, gas-gas or the liquid-liquid heat exchanger of industries such as chemical industry, oil, metallurgy, medicine, system alkali, light industry, electric power, Thermal Power Engineering of being used for.
Background technology
At present, heat exchanger tube is widely used in as a kind of common heat exchanger heat exchange element in the devices such as heat exchanger that industries such as chemical industry, oil, metallurgy and Thermal Power Engineering use, reboiler, carry out the exchange and the transmission of heat, it is a kind of crucial heat exchange element, in order to improve its thermal efficiency, guarantee heat exchange amount, people have carried out a large amount of tests from each side such as material, size, profiles, attempt to search out heat exchanger tube form efficiently, wherein the shape of heat exchanger tube inside and outside wall directly has influence on speed, resistance, the heat exchange efficiency that heat transferring medium flows.The inner wall shape of existing heat exchanger tube is based on light pipe, and along with all trades and professions are more and more higher to energy-conservation important understanding, the height of heat exchange efficiency has become the important indicator of heat exchanger, and it is extremely urgent therefore to design the higher heat exchanger tube of a kind of efficient.
Summary of the invention
The purpose of this utility model provides the higher inner groovy structure efficient heat-exchanging pipe of a kind of heat exchange efficiency.
The technical solution of the utility model is:
A kind of inner groovy structure efficient heat-exchanging pipe is characterized in that its inside pipe wall is provided with linear or spiral groove along axis direction, and the cross sectional shape of this groove is rectangle, square or zigzag.
Meanwhile, the surface of exchange heat pipe is carried out a series of processing and is also had tangible effect to improving heat exchange efficiency, and therefore, the pipe outer wall of above-mentioned heat exchanger tube is except that can be light pipe, also can be ripple struction or helicitic texture, or pipe outer wall and inside pipe wall there is the same grooves structure.
The beneficial effects of the utility model:
1, simple in structure, improvement by exchange heat pipe internal structure, improve the hydrodynamic performance of heat transferring medium, make it to realize best combination, friction along the linear straight trough or the helicla flute of heat exchanger tube axis direction can guarantee heat transferring medium and inside pipe wall produces turbulent flow at inside pipe wall, helps improving contact area again, easily form the nucleus of boiling, thereby improve heat exchange efficiency.
2, applied range is in all kinds of heat exchangers that can be applicable to use in the industries such as chemical industry, oil, metallurgy, medicine, system alkali, light industry, electric power, Thermal Power Engineering.
Description of drawings
Fig. 1 is one of cross section partial structurtes schematic diagram of heat exchanger tube of the present utility model.
Fig. 2 be heat exchanger tube of the present utility model cross section partial structurtes schematic diagram two.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one.
As shown in Figure 1.
A kind of inner groovy structure efficient heat-exchanging pipe, its inside pipe wall is provided with some linear grooves 1 that are adjacent layout along axis direction, and the cross sectional shape of this groove 1 is rectangle (also can be square or zigzag).Groove 1 removes the straight trough shape structure that can be along axis direction, also can be the helical structure along axis direction.Pipe outer wall or be the light wall also can be wave structure, also can be the groove structure identical shaped with inwall.
Embodiment two.
As shown in Figure 2.
A kind of inner groovy structure efficient heat-exchanging pipe, its inside pipe wall is provided with some linear grooves 2 that are adjacent layout along axis direction, and the cross sectional shape of this groove 2 is a zigzag.Groove 2 removes the straight trough shape structure that can be along axis direction, also can be the helical structure along axis direction.
Among the embodiment one and two, the shape of the pipe outer wall (outer surface) of heat exchanger tube is identical with existing structure, can adopt arbitrary shape, both can be light pipe, also can be bellows, also can be the groove structure identical with inside pipe wall.Its material can be selected carbon steel, stainless steel, monel etc. for use, and wherein stainless steel, monel have the good advantage of antiseptic property, but its cost is a little more than carbon steel material.
Claims (3)
1, a kind of inner groovy structure efficient heat-exchanging pipe is characterized in that its inside pipe wall is provided with linear or spiral groove along axis direction, and the cross sectional shape of this groove is rectangle, square or zigzag.
2, inner groovy structure efficient heat-exchanging pipe according to claim 1 is characterized in that its pipe outer wall or for light pipe or for ripple struction or for helicitic texture.
3, inner groovy structure efficient heat-exchanging pipe according to claim 1 is characterized in that its pipe outer wall and inside pipe wall have the same grooves structure.
