Abstract
The utility model discloses an anticorrosive high-efficiency heat exchange tube, which comprises a tube body. The tube body is an anticorrosive tube body. A group of anticorrosive fins are arranged on the outer wall of the tube body. A group of anticorrosive fins are arranged on the outer wall of the anticorrosive tube body, and an internal thread is arranged on the inner wall of the anticorrosive tube body, so that the heat transfer areas of the outer wall and inner wall of the tube body are enlarged, and the heat exchange efficiency of the tube body is effectively improved; and moreover, the anticorrosive tube body and the anticorrosive fins are have anticorrosive effects, so that the service life of the heat exchange tube cannot be shortened when used for a high-concentration high-corrosion chemical fluid environment. The heat exchange tube is rational and simple in structure, low in cost and convenient to use, and an ideal heat exchange effect can be achieved by a small number of heat exchange tubes when the heat exchange tube is used.
Description
Technical field
The utility model relates to a kind of heat exchange element, especially a kind of anticorrosion efficient heat-exchanging pipe.
Background technology
Heat exchanger tube is a kind of heat exchange element, places during use within the cylindrical shell, is used for the exchange of heat between two media.The cooling of need lowering the temperature of the chemical fluid of a lot of high concentrations, highly corrosive is arranged in industrial refrigeration; And prior art generally adds middle anticorrosion plate type heat exchanger in handpiece Water Chilling Units; Or adding anticorrosion light pipe formula heat exchanger at the direct-cooling type cooling-water machine, anticorrosion plate type heat exchanger is big at loss of refrigeration capacity and the wastage that this heat transfer process produces in the middle of using; And it is little to adopt light pipe to make the corrosion-proof heat exchanger heat exchange area, and heat exchange property is poor, and the heat exchanger tube use amount is big; Simultaneously because the plain tube inner wall smooth, easy scale formation in use is once fouling will produce very big thermal resistance by the heat exchanging device; Influence the heat exchange effect, not only increased cost heat exchanger volume is increased, when this heat exchanger tube is used for the handpiece Water Chilling Units heat exchange; The heat exchange efficiency of handpiece Water Chilling Units is very low, has caused very big the source ability and the wasting of resources.At present, copper material high efficient heat exchanging Manifold technology is very ripe with warp in the efficient heat-exchanging pipe, but antiseptic effect is poor.Therefore be badly in need of occurring that a kind of cost is lower, the anticorrosion efficient heat-exchanging pipe of good effect of heat exchange and long service life.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides that a kind of cost is lower, the anticorrosion efficient heat-exchanging pipe of good effect of heat exchange and long service life, satisfies the demand of industrial refrigeration.
The utility model solves the technical scheme that its technical problem adopts: this anticorrosion efficient heat-exchanging pipe, comprise body, and body is anticorrosion body, tube wall is provided with one group of anticorrosion fin.Heat=the heat flow density of the heat exchanger tube * heat transfer area * logarithm temperature difference (Q=K*A* △ t); From following formula, can find out and to improve heat (Q); Have only three approach, the logarithm temperature difference (△ t) is because of the applying working condition decision, and the parameter that can change has only heat flow density (K) and heat transfer area (A); And will change heat flow density (K) also is a very difficult thing; From the last visible parameter that changes heat transfer area (A) is to improve the main path of heat, and smooth wall pipe unit length heat exchange area is few, and the number of tubes of unit heat is many; Answer the heat exchange tube sheet of heat exchanger just must strengthen the terrible corresponding increasing of heat exchanger shell simultaneously if the stringing of pipe is heterogeneous, the increase that so consumed cost will be at double.One group of anticorrosion fin is set on anticorrosion tube wall, can reduces quantity, the minimizing heat exchanger volume of heat exchanger tube in the heat exchanger when being applied in the heat exchanger tube device and can not reduce the heat exchanger heat exchange efficiency again, effectively avoid many drawbacks of traditional smooth wall pipe.
Further, body is the anticorrosion body of titanium alloy.The anticorrosion body of titanium alloy has antisepsis preferably, and service life is longer.
Inboard wall of tube body is provided with internal thread.Internal thread the heat transfer area that can increase inboard wall of tube body is set, thereby improved the heat of heat exchanger tube.
Anticorrosion fin sidewall is provided with anticorrosion heat exchange ring.Can increase the heat transfer area of tube wall so once more, improve thermal conversion efficiency.
Further, anticorrosion fin is the screw thread linear structure.Be convenient to processing like this, also be convenient to fluid and flow.
The effect that the utility model is useful is: the utility model rational in infrastructure, simple; Through one group of anticorrosion fin being set on the anticorrosion tube wall and on anticorrosion inboard wall of tube body, establishing internal thread; Improve the heat transfer area of tube wall, inboard wall of tube body, thereby effectively improve the heat exchange efficiency of body; And anticorrosion body, anticorrosion fin all have corrosion-resisting function preferably, and in the chemical fluid environment of high concentration, highly corrosive, using can reduction of service life.The utility model cost is low, only needs a small amount of heat exchanger tube just can reach desirable heat exchange effect during use, and is easy to use.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: this anticorrosion efficient heat-exchanging pipe in the present embodiment, comprise body 1, body 1 is anticorrosion body, and body 1 outer wall is provided with one group of anticorrosion fin 2, and anticorrosion fin 2 sidewalls are provided with anticorrosion heat exchange ring 4, and anticorrosion fin 2 is the screw thread linear structure.Body 1 is the anticorrosion body of titanium alloy.Body 1 inwall is provided with internal thread 3.
The utility model can be through titanium alloy plain tube rail system extrusion modling processing fin, internal thread, and the smooth thickness of pipe 1.2 ㎜ are squeezed into rib shape with titanium alloy, and fin becomes the screw thread linear structure, forms fin end face, fin bottom surface and fin side.Fin height is 0.5 ㎜, and the fin top width is 0.3 ㎜, and spacing of fins is 0.7 ㎜.The heat exchange area that makes the utility model is 3 times more than of smooth wall pipe heat exchange area, improves the heat exchange efficiency of heat exchanger tube.
The utility model has increased the heat exchange area of unit length and weight, is processed into fin end face, fin bottom surface and fin side to original plain tube outer wall.So plain tube will have more two fin sides; And be processed into 30 fins to the inwall of plain tube; Making the utility model unit length heat exchange external surface area is about 3 times of smooth wall pipe heat exchange area; Thereby internal surface area has increased about the 1.5 times heat exchanger tube quantity that realized that the unit heat exchanger tube uses and has reduced about 2.5 times, and the utility model has not only reduced the consumption of heat exchanger heat-exchanging tube, has also reduced volume, the weight of equipment simultaneously.The consumptive material of the equipment of practicing thrift, the efficiency of raising also greatly reduces the cost of equipment.The utility model is applicable in the heat exchangers such as efficient corrosion resisting flooded evaporator, anticorrosion heat regenerator, can effectively improve the exchange capability of heat of heat exchanger, thereby the material usage that reduces heat exchanger has reduced volume and material cost.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
