Abstract
The utility model discloses a needle rib votator, including heat exchanger shell, set up shell side fluid inlet in the heat exchanger shell upper end, set up the shell side fluid issuing at the heat exchanger shell lower extreme, and shell side fluid inlet, shell side fluid issuing pass through heat exchanger shell inner chamber intercommunication, spiral heat exchange tube places in heat exchanger shell, and spiral heat exchange tube 's tube side fluid inlet stretches out the heat exchanger shell lower extreme, and spiral heat exchange tube 's tube side fluid inlet stretches out the heat exchanger shell upper end, the utility model discloses it is great effectively to overcome traditional heat exchanger volume, the lower shortcoming of coefficient of heat transfer to because the spiral pipe has the needle rib outward, can make the shell side fluid produce strong torrent effect, and then increase the heat transfer efficiency of wall, the utility model discloses simple structure, the preparation is convenient, and the practicality is strong.
Description
Technical field
This utility model relates to heat-transfer equipment technical field, especially a kind of pin rib votator.
Background technology
Heat exchanger, also known as heat exchanger, is a kind of equipment that heat passes to cryogenic object from high temp objects.No matter heat exchanger all plays an important role in commercial production or daily life.
Traditional heat exchangers is generally shell-and-tube heat exchanger and plate type heat exchanger, and the housing of shell-and-tube heat exchanger mostly is cylindrical shape, and inside is parallel heating surface bank, and the two ends of heat-transfer pipe are fixed and on tube sheet.Need the fluid flowing in pipe and outside pipe respectively of heat exchange.Plate type heat exchanger is by a kind of heat exchanger of a series of sheet metal closed assemblies with certain bellows-shaped.Form thin rectangular shape passage between various plates, carry out heat exchange by plate.
Traditional heat exchanger volume is relatively big, and heat transfer coefficient is relatively low, and in runner, the nowed forming of fluid is simple, it is difficult to form strong turbulence effects so that the heat transfer efficiency of wall is very low.
Summary of the invention
Technical problem to be solved in the utility model is: providing a kind of pin rib votator, this device volume is less, and fluid produces strong turbulent flow in flowing so that heat transfer efficiency increases, to overcome the deficiencies in the prior art.
This utility model is achieved in that
A kind of pin rib votator, including heat exchanger shell, in heat exchanger shell upper end, shell-side fluid import is set, in heat exchanger shell lower end, shell side fluid outlet is set, and shell-side fluid import, shell side fluid outlet are by heat exchanger shell inner space, spiral heat exchange tube is placed in heat exchanger shell, and heat exchanger shell lower end is stretched out in the tube side fluid import of spiral heat exchange tube, and heat exchanger shell upper end is stretched out in the tube side fluid import of spiral heat exchange tube.
In aforesaid a kind of pin rib votator, described spiral heat exchange tube is distributed in heat exchanger shell in the shape of a spiral, and the centerline parallel of spiral heat exchange tube centrage and heat exchanger shell or overlap.
In aforesaid a kind of pin rib votator, uniform pin rib on the outer surface of spiral heat exchange tube, by arranging pin rib on spiral heat exchanger, when the pin rib having fluid outside heat exchanger tube, pin rib has slight vibration, unsuitable fouling；Needle tubing outside heat exchanger tube adds heat transfer area, improves heat transfer efficiency；When fluid is by heat exchanger tube, adds the disturbance of tube side fluid, further increase heat transfer efficiency.
In aforesaid a kind of pin rib votator, the two ends of described heat exchanger shell are tapered structure, and this structure is conducive to the collection of tube side fluid to flow out.
Owing to have employed technique scheme, compared with prior art, this utility model can effectively overcome traditional heat exchangers volume bigger, heat transfer coefficient is relatively low, and in runner, the nowed forming of fluid is simple, it is difficult to form strong turbulence effects, the heat transfer efficiency making wall is very low, this utility model simple in construction, easy to make, practical.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is of the present utility model partly to cut open schematic diagram.
Detailed description of the invention
Embodiment of the present utility model: a kind of pin rib votator, as shown in drawings, including heat exchanger shell 3, the two ends of this heat exchanger shell 3 are tapered structure, in heat exchanger shell 3 upper end, shell-side fluid import 2 is set, in heat exchanger shell 3 lower end, shell side fluid outlet 7 is set, and shell-side fluid import 2, shell side fluid outlet 7 is by heat exchanger shell 3 inner space, spiral heat exchange tube 4 is placed in heat exchanger shell 3, and the tube side fluid import 6 of spiral heat exchange tube 4 stretches out heat exchanger shell 3 lower end, heat exchanger shell 3 upper end is stretched out in the tube side fluid import 1 of spiral heat exchange tube 4.
Wherein spiral heat exchange tube 4 is distributed in heat exchanger shell 3 in the shape of a spiral, and the centerline parallel of spiral heat exchange tube 4 centrage and heat exchanger shell 3 or overlap, and on the outer surface of spiral heat exchange tube 4 uniform pin rib 5.
Time specifically used
A kind of fluid enters heat exchanger tube from the import 6 of tube side fluid, flow along the spiral heat exchange tube 4 with pin rib 5, simultaneously, one other fluid enters heat exchanger from shell-side fluid import 2, tube side fluid fluid generation disturbance when the pin rib 5 flowed through outside spiral heat exchange tube 4, add heat exchange efficiency, tube side fluid and shell-side fluid complete the transmission of heat in the process of flowing, reach the purpose of heat exchange, then tube side fluid exports 1 outflow heat exchanger from tube side fluid, shell-side fluid passes through shell side fluid outlet 7 outflow heat exchanger, and heat exchange completes.
Above-described embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to be carried out; can not as limiting protection domain of the present utility model; all equivalent variations made according to this utility model spirit or modification, all should be encompassed in protection domain of the present utility model.
