Abstract

The invention discloses a pin-fin spiral heat exchanger, which comprises a heat exchanger shell; a shell pass fluid inlet is formed in the upper end of the heat exchanger shell; a shell pass fluid outlet is formed in the lower end of the heat exchanger shell, and the shell pass fluid inlet and the shell pass fluid outlet communicate through an inner cavity of the heat exchanger shell; a spiral heat exchange tube is placed in the heat exchanger shell, and a tube pass fluid inlet of the spiral heat exchange tube extends out of the lower end of the heat exchanger shell; and a tube pass fluid inlet of the spiral heat exchange tube extends out of the upper end of the heat exchanger shell. The pin-fin spiral heat exchanger disclosed by the invention is capable of effectively overcoming the disadvantage that a traditional heat exchanger has a relatively big size and a relatively low heat transfer coefficient; moreover, as pin fins are arranged on the outside of the spiral tube, shell pass fluid can be enabled to generate a strong turbulence effect, and heat transfer efficiency of a wall surface is further increased; the pin-fin spiral heat exchanger disclosed by the invention is simple in structure, convenient to manufacture and high in practicability.

Description

A kind of pin rib votator
Technical field
The present invention 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 heat being passed to cryogenic object from high temp objects.No matter heat exchanger all plays an important role in industrial 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 fixing with on tube sheet.Need the fluid flowing in pipe and outside pipe respectively of heat exchange.Plate type heat exchanger is by a series of a kind of heat exchanger with the sheet metal closed assembly of certain bellows-shaped.Form thin rectangular shape passage between various plate, carry out exchange heat by plate.
Traditional heat exchanger volume is comparatively large, and heat transfer coefficient is lower, and in runner, the nowed forming of fluid is simple, is difficult to form strong turbulence effects, makes the heat transfer efficiency of wall very low.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of pin rib votator, this device volume is less, and fluid produces strong turbulent flow in flowing, and heat transfer efficiency is increased, to overcome the deficiencies in the prior art.
The present invention is achieved in that
A kind of pin rib votator, comprise 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 is 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 center line 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 the collection that this structure is conducive to tube side fluid is flowed out.
Owing to have employed technique scheme, compared with prior art, it is larger that the present invention can effectively overcome traditional heat exchangers volume, heat transfer coefficient is lower, and in runner, the nowed forming of fluid is simple, is difficult to form strong turbulence effects, make the heat transfer efficiency of wall very low, structure of the present invention is simple, easy to make, practical.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 of the present inventionly partly cuts open schematic diagram.
Detailed description of the invention
Embodiments of the invention: a kind of pin rib votator, as shown in drawings, comprise 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 heat exchanger shell 3 lower end is stretched out in the tube side fluid import 6 of spiral heat exchange tube 4, 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 center line and heat exchanger shell 3 or overlap, and on the outer surface of spiral heat exchange tube 4 uniform pin rib 5.
During concrete use
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 is fluid generation disturbance when flowing through the pin rib 5 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 object of heat exchange, then tube side fluid exports 1 outflow heat exchanger from tube side fluid, shell-side fluid is by shell side fluid outlet 7 outflow heat exchanger, and heat exchange completes.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not as limiting the scope of the invention; all equivalent variations of doing according to Spirit Essence of the present invention or modification, all should be encompassed in protection scope of the present invention.
