Abstract
The utility model provides a kind of thermoexcell, comprises body, and body cross section presents ellipticity, is to flatten to obtain on the basis of pipe; It is curved that the outer surface of body presents spiral torsional, is that screw twisted obtains on the basis that pipe flattens; It is curved that the inner surface of body presents internal-rib spiral torsional, is to obtain with body screw twisted on the basis that pipe adds internal-rib; The material of body is metal material; Its main structure parameters feature comprises: major semiaxis a, helical pitch s, rib height e, angle of rib β, rib number n; Special construction of the present utility model, can improve heat exchange area, strengthens the mixability between heat transferring medium, reduces resistance during fluid flowing, effectively improves heat exchange efficiency, makes heat transfer effect be 2 ~ 3 times of benchmark pipe.
Description
Technical field
The utility model relates to petrochemical industry energy industry technical field of heat exchange, refers more particularly to a kind of thermoexcell.
Background technology
Destroy in face of two large challenges in energy shortage waste and environmental pollution, for realizing scientific and technological progress and social sustainable development, except tapping a new source of energy, also need to improve the clean utilization efficiency of the energy, and be exactly important channel and the method for the efficiency utilization energy to the strengthening of diabatic process and optimization.A kind of thermoexcell described in the utility model is exactly the fine embodiment that heat exchanging process intensification and exchange heat pipe are optimized, make heat transferring medium while longitudinal flow by the special construction of body surfaces externally and internally, produce rotational flow and secondary flow, mixability between enhance fluid and flow-disturbing degree, heat exchange between strengthening fluid, makes heat transfer effect strengthen.Simultaneously between heat-exchanging tube bundle because helically twisted structure can realize restraining self-supporting, save conventional shell-and-tube heat exchanger and fix required deflection plate or rod baffle, reduce flow resistance between fluid, make comprehensive heat transfer effect obviously efficient, there are higher Prospect of R & D and engineer applied potentiality.
Summary of the invention
The utility model provides a kind of thermoexcell, can effectively solve the problems such as heat transfer process efficiency is low, fluid flow resistance is large, longitudinal flow and rotational flow and Secondary Flow that both cause is produced when pipe structure feature makes fluid flow, enhance the disturbance in boundary layer, mixability between enhance fluid, strengthens heat exchange efficiency.
The utility model provides a kind of thermoexcell, comprises body, and its architectural feature is: major semiaxis (semi-minor axis), helical pitch, rib are high, the angle of rib, rib number, and material is metal material.
The utility model provides a kind of thermoexcell, and its body shape of cross section is rendered as ellipticity, and concrete flattening degree depends on the value of major semiaxis (semi-minor axis).
The utility model provides a kind of thermoexcell, and its outer surface of tube body presents screw twisted shape, and concrete screw twisted degree depends on the value of major semiaxis (semi-minor axis), helical pitch.
The utility model provides a kind of thermoexcell, and its inner surface of tube body presents internal-rib screw twisted shape, and concrete screw twisted degree depends on that major semiaxis (semi-minor axis), helical pitch, rib are high, the value of the angle of rib, rib number.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Fig. 2 is cross-sectional structure schematic diagram of the present utility model; Fig. 3 is outer surface structure schematic diagram of the present utility model; Fig. 4 is inner surface structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is done and further describes in detail.
Refer to Fig. 1, it comprises Fig. 2 body cross-sectional structure schematic diagram, Fig. 3 outer surface of tube body structural representation and Fig. 4 inner surface of tube body structural representation, the utility model provides a kind of thermoexcell, comprise body, key structural feature is: major semiaxis (semi-minor axis), helical pitch, rib are high, the angle of rib, rib number.The larger semi-minor axis of major semiaxis is less, and body flattening degree is higher, and body shape of cross section is more flat; Helical pitch is less, and outer surface of tube body structure is compacter, and screw twisted degree is higher; Rib Gao Yuegao, the angle of rib is less, and rib number is more, and inner surface of tube body structure is more complicated.The ellipticity flattening degree of body cross section is higher, and during fluid flowing, boundary layer flow-disturbing degree is higher, and fluid chemical field degree is higher, and heat exchange is more abundant.Outer surface of tube body structure is compacter, goes out the rotational flow that longitudinal flow produces outward stronger during extratubal fluid flowing, more long more abundant with the comes into heat transferring contact time of tube fluid.Tubular body structure is more complicated, longitudinal direction stream, rotating flow and Secondary Flow that tube fluid flowing produces are stronger, near boundary layer, flow-disturbing intensity increases, mixability is more even, the effect that the coefficient of heat transfer increases is better than the effect that resistance increases, comprehensive heat transfer effect is strengthened, and the 2-3 that can reach common heat exchanger tube doubly, has very high research and development potentiality and future in engineering applications.
