Abstract
The utility model relates to a spiral ripple heat exchange tube used for a heat exchanger; a heat exchange tube is a spiral ripple tube; the tube openings at two ends are the connection ends fixedly connected with the supporting structure of the heat exchanger and are necking mouth structures. A multi-head spiral ripple is arranged on the body of the heat exchange tube; a drop pit the surface of which is sprayed by sand is arranged on the spiral ripple; a thread pitch is 20 to 100mm.The utility model has novel design, effectively increases the heat exchange area through the spiral ripple arranged on the heat exchange tube to lead the liquids participated in the heat exchange to be fully stirred and improves the heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of heat exchanger component, especially a kind of heat exchanger tube of heat exchanger.
Background technology
Heat exchanger is widely used in fields such as refrigeration, air-conditioning, chemical industry.Heat exchanger tube is as the vitals in the heat exchanger, and common heat exchanger tube is the smooth pipe of inside and outside wall, and fluid is usually with the inside and outside wall of laminar flow pattern by heat exchanger tube.Fluid at contact heat-exchanging pipe inside and outside wall forms the boundary layer, and the boundary layer can suppress the heat transmission of whole fluid, reduces the heat exchange efficiency of heat exchanger.And along with the development of society, metals resources is more and more in short supply, and the cost of metal material is more and more higher, and therefore, the service efficiency of metal material must improve.
Summary of the invention
In order to overcome the above-mentioned inside and outside smooth low deficiency of heat exchanger tube heat exchange efficiency of tube wall, the utility model provides a kind of heat exchanger corrugated spiral heat-exchange tube that can effectively improve heat exchange efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of heat exchanger corrugated spiral heat-exchange tube, the heat exchanger tube two ends mouth of pipe is the link of fixedlying connected with the heat exchanger supporting construction, between two links, be the heat exchange body, the described exchange body that changes is provided with helical corrugation, the pitch B of described helical corrugation is 20～100mm, and groove depth A is 2～10mm, and groove width C is 1～7mm, helical corrugation is provided with blasting treatment, forms pit.By helical corrugation is set, increased heat exchange area on the one hand, on the other hand, changed the inside and outside fluid direct of travel of heat exchanger tube, fluid is flowed along the helical corrugation of helical bellows, increased the contact area and the mobile flow process of fluid heat exchange.The setting of surface sand-blasting, when further increasing heat exchange area, staggered mixed flow can fully be stirred fluid and is closed when making a part of fluid flow through helical corrugation, has effectively eliminated the boundary layer, makes fluid obtain abundant heat exchange.
In order to guarantee control certain heat exchanger time when increasing heat exchange area, further: the pitch B of described helical corrugation is 20-100mm, and pitch B is big more, and flow through time on heat exchanger tube surface of fluid is just short more, and the speed of fluid is fast more.
In order to guarantee to have bigger heat exchange area in certain pitch B, further: described helical corrugation has 2～12, and concrete several according to heat exchange caliber and the decision of heat exchange amount.
Fixedly connected with the heat exchanger supporting construction for the ease of heat exchanger tube, guarantee that heat exchanger tube and supporting construction junction have excellent sealing performance, further: described link is a throat structure.
The utility model modern design is provided with helical corrugation by being arranged on the tube wall, effectively increased heat exchange area, by handling at the helical corrugation surface sand-blasting, fluid is fully mixed again, has improved heat exchange efficiency.

Among the figure: 1. link 2. heat exchange bodys 3. helical corrugations 4. pits
The specific embodiment
A kind of heat exchanger corrugated spiral heat-exchange tube as shown in Figure 1 and Figure 2, the heat exchanger tube two ends mouth of pipe are the link 1 of fixedlying connected with the heat exchanger supporting construction, and described link 1 is a throat structure.Be heat exchange body 2 between two links 1, the described exchange body 2 that changes is provided with helical corrugation 3, the pit 4 that has surface sand-blasting to handle on helical corrugation 3.Described helical corrugation 3 has 2～12, and pitch is 20-100mm.Groove depth A is 2～10mm, and groove width C is 1～7mm.
Heat exchanger described in the utility model adopts the pipe material to process by special equipment with corrugated spiral heat-exchange tube, pipe can adopt high thermal conductivity material, as copper, brass, aluminium or corrosion-resistant material, as various Heat Conduction Material pipes such as stainless steel, corronil, titanium, titanium alloys, for being easier to make helical corrugation, pipe more trends towards thin-walled.Its manufacturing procedure is: process helical corrugation by special equipment on selected pipe, again by reducing equipment, the link of heat exchanger tube is pressed into throat structure, link can have certain tapering, so that heat exchanger tube is connected with supporting construction, do blasting treatment on its surface then.
