Abstract
The invention relates to a spring type efficient antifreezing sleeve heat exchanger which comprises a heat exchange pipe I, a heat exchange pipe II, a heat exchanger shell, a fluid I inlet, a fluid I outlet, a fluid II inlet and a fluid II outlet, wherein the heat exchange pipe I and the heat exchange pipe II form a sleeve, the heat exchange pipe I is an external pipe, the heat exchange pipe II is an internal pipe, the sleeve is of a helical structure with specific thread pitch, and the appearance of the sleeve is like a spiral spring to form a spiral hollow cylinder. According to the invention, structure improvement is realized on the basis of common sleeve heat exchangers, so that efficient heat exchange and freezing prevention can be achieved; and the heat exchanger is simple in structure, small in volume, light in weight, low in price and convenient to install.
Description
Technical field
The present invention relates to a kind of heat exchanger, be specifically related to a kind of spring double-tube heat exchanger, realize high efficient heat exchanging and antifreeze by spring sleeve structure.
Background technology
Heat exchanger is a kind of universal industrial equipment be widely used, but often makes place's bursting by freezing such as elbow, tube connector of heat exchanger winter because there is residual water inside, thus have impact on the use of whole device systems, even large accident can occur.
Screw shell is, by the method for rolling distortion processing, smooth straight is processed into various spirality special pipe, and screw shell, due to the architectural characteristic of its uniqueness, the efficiently feature such as heat transfer efficiency and Secondary Flow, is widely used in the industry such as chemical industry, power.
Summary of the invention
For the problems referred to above and technology, the object of the present invention is to provide a kind of spring casing tube high-efficiency freeze-proof heat exchanger, it can effectively utilize the unique texture of spring type spiral sleeve pipe, reaches antifreeze and object that is high efficient heat exchanging.
The technical solution used in the present invention is as follows:
A kind of spring casing tube high-efficiency freeze-proof heat exchanger, comprise draw together heat exchanger tube one, heat exchanger tube two, heat exchanger shell, fluid one import, fluid one export, fluid two import, fluid two outlet, heat exchanger tube one and heat exchanger tube two form sleeve pipe, heat exchanger tube one is outer tube, heat exchanger tube two is interior pipe, sleeve pipe is the helical structure of specific pitch, and profile, as the spring spiraled, forms the hollow cylinder spiraled.
In the hollow cylinder that described sleeve pipe is formed, between the outer tube tube gap of spring sleeve pipe, between sleeve pipe and the space of heat exchanger shell, be filled with elastic foam polyurethane.
Be respectively two kinds of fluids in described heat exchanger tube one and heat exchanger tube two, two kinds of fluids are reverse flow, and temperature is different, in double-cyclone, complete heat exchange.
Described two kinds of fluids can be fluids of different nature, as gas gas, gas-liquid, liquid liquid.
Operation principle of the present invention:
Spiral coil can make extratubal fluid and tube fluid do the flowing of reverse double-cyclone, fluid in helix tube and outside pipe is not stopping in rotation, because centrifugal action makes pipeline center's partial velocity higher, and the fluid at tube wall place is less due to centrifugal force, exacerbates mixing of near wall place fluid and core flow, increase turbulence intensity, greatly enhance the heat convection of fluid and tube wall, the heat transfer coefficient of heat exchanger is increased, achieves efficient heat transfer, antiscale.
When that there's a sudden fall in temperature is even lower to subzero, water now in heat exchange pipeline will freeze, namely water once can cause the volumetric expansion of water in body after freezing, when frozen water after expansion is enough large to tube wall thrust, because the spring pipeline that spirals has enough elastic space deposits, expansion thrust can cause spring spiral pipeline elastic force distortion, thus eliminate water in the volumetric expansion process being converted into ice to inner-walls of duct produce expansion pressure, avoid the bursting by freezing of pipeline to damage.
Advantage of the present invention:
The present invention improves through structure on ordinary casing heat exchanger basis, adopt the unique texture of spring type spiral sleeve pipe, achieve high efficient heat exchanging, low temperature is antifreeze, structure is simple simultaneously, volume is little, lightweight, corrosion-resistant, good antiscale property, low price, the scope of application are wide, easy for installation.
