Abstract
A heat exchange pipe used for a heat exchanger has a network shape groove on the outer wall and reticulated cog whose angle is in the direction of fluid flow. Such a structure has the following advantages: firstly, the heat exchange area and roughness of the pipe are increased to improve heat exchange performance; secondly, multidirectional cross grooves and cog and the diamond angle tear apart the laminar layer of pipe wall fluid in normal and tangential directions to further enhance heat exchange performance; thirdly, reticulated cog on the pipe inner wall functions as a support to increase mechanical intensity of the pipe.
Description
Affiliated technical field
The utility model relates to the heat exchanger tube that a kind of heat exchanger is used.
Background technology
At present, known heat exchanger tube has fin, spiral, ripple and interpolation disturbing flow device etc. in order to the version of enhanced heat exchange effect, these versions can be destroyed the laminar sublayer of fluid in certain degree, reach the purpose of enhanced heat exchange, also have different drawbacks simultaneously.As the gilled tube complex structure, the manufacturing cost height, helix tube, bellows can only produce unidirectional flow-disturbing effect, and have weakened the mechanical strength of heat exchanger tube, and the interpolation disturbing flow device is safeguarded complicated, is not easy to clean etc.
Summary of the invention
In order when improving heat exchange efficiency, to reduce manufacturing cost, increase the mechanical strength of heat exchanger tube, convenient installation, O﹠M, the enhanced heat exchange structure that the utility model heat exchanger tube is adopted is: heat exchanger tube 1. outer wall have by left-handed groove 2. with the dextrorotation groove 3. intersect constitute have a diamond-mesh meshed grooves 4., inwall has by left-handed fin and 6. has a diamond-mesh netted fin 8. with 7. the dextrorotation fin constitutes, the direction that 5. water caltrop of outer wall rhombus flows over against horizontal fluid of plunderring tube wall, the direction that 9. water caltrop of inwall rhombus flows over against tube fluid.Adopt the advantage of this version to have: on the one hand, the heat exchange area of pipe and roughness obtain increasing, and the heat exchange effect is improved; On the other hand since groove that intersects and fin with and the water caltrop that forms can tear the laminar sublayer of tube wall fluid from tube wall face normal direction and tangential both direction, thereby improve the heat exchange effect further; Again on the one hand, because tube wall has netted fin to play the support reinforcing effect, the mechanical strength of pipe is strengthened.
Beneficial effect
The utility model heat exchanger tube can be realized by simple technology in the process of making, can reduce manufacturing cost, when improving heat exchange efficiency, improved the mechanical strength of pipe, be convenient to installation, operation and maintenance, solved the contradiction between raising heat exchange efficiency and reduction manufacturing cost, enhance mechanical strength and convenient installation, operation, the maintenance well, compare with common heat exchanger tube, heat exchange efficiency is the highest to improve 30%, for energy savings, cut down the consumption of energy significant.
Description of drawings
Fig. 1 is the outer tube surface front view.
Fig. 2 is the pipe profilograph.
Fig. 3 is the pipe cross-sectional view.
The specific embodiment
The utility model heat exchanger tube forms fin at inwall by from outer wall roll extrusion groove the time during fabrication simultaneously, and manufacture craft is simple, and tubing is not had specific (special) requirements, can be used for steel pipe, stainless steel tube, copper pipe, aluminum pipe etc.According to different installation requirements, the light pipe of suitable length can be reserved in the pipe two ends, so that with tube plate expanded-connecting or welding, its installation, O﹠M are very simple, can be applicable in the widely used heat exchangers of industry such as the energy, chemical industry, as the heater of thermal power generation station-service, oil cooler, condenser, air cooler etc.
