Description

A kind of spiral baffle heat exchanger
Technical field:The present invention relates to a kind of hot swapping.
Background technology:
Spiral baffle heat exchanger, generally comprises both ends and is fixedly connected with the heat exchanger shell of tube sheet, is installed in housing Helical form disc and donut, through being distributed in the heat-exchanging tube bundle of different size quantity in helical form disc and donut, be connected with water The water cover of mouth, oil inlet and outlet, hollow cylinder core pipe.During work, along the medium of heat exchanger helical pipe flow direction because of centrifugal force Effect make it that the velocity of medium close to intermediate region is slower, on the one hand can cause helical baffles and intermediate cylindrical core pipe or housing Gap location there is leakage current phenomenon, and local deposits may be caused dirt occur, on the other hand so that changing in intermediate region Adopting heat pipes for heat transfer efficiency is low.
The content of the invention:
It is basically identical, effectively that the goal of the invention of the present invention is to provide a kind of flow velocity of medium in heat exchanger shell everywhere Prevent medium from the spiral baffle heat exchanger of the gap of helical baffles and intermediate cylindrical core pipe or housing leakage.
The present invention, which is achieved in that, to be fixedly connected with the heat exchanger shell of tube sheet including both ends, is installed in heat exchanger shell Internal helical form disc and donut, through the several heat exchange for being distributed in helical form disc and donut and being connected with both ends tube sheet Manage, be arranged on the end cap at heat exchanger shell both ends, the liquid-inlet and liquid discharge that are arranged on the side wall of heat exchanger shell both ends Mouthful, be provided with and heat exchanger tube and core pipe in helical form disc and donut axle center and the core pipe that is connected with both ends tube sheet, end cap The inlet and outlet being connected, it is particular in that is provided with several piece along in the plate face of the helical form disc and donut hand of spiral Fin.
During work, into the medium in heat exchanger shell along helical form disc and donut helical flow, in the stop of fin Under, block the trend that medium is inclined to heat exchanger shell because of the effect of centrifugal force so that medium in heat exchanger shell everywhere Flow velocity tend to consistent, and then avoid the medium of prior art from helical baffles and intermediate cylindrical core pipe or the gap of housing The appearance of the phenomenon of leakage.
Here, helical form disc and donut by fan-shaped helical form baffling Slab element connection that several pieces helically bend and Into.
Fin is vertically fixed in the plate face of helical form disc and donut, on the surface of fin and helical form disc and donut The direction of the flowing of the medium of helical flow maintains an equal level.
The present invention is compared with the prior art, basically identical, effectively anti-with flow velocity of the medium in heat exchanger shell everywhere The advantages of only medium is revealed from the gap of helical baffles and intermediate cylindrical core pipe or housing.

Embodiment:
The present invention is described in further detail in conjunction with drawings and examples:
As shown in Figure 1, 2, the present invention is fixedly connected with the heat exchanger shell 7 of tube sheet 5 including both ends, is installed in heat exchanger shell Helical form disc and donut 9 in body 7, through being distributed in helical form disc and donut 9 and what is be connected with both ends tube sheet 5 several changes Heat pipe 8, the end cap 4 for being arranged on 7 both ends of heat exchanger shell, the liquid-inlet 6 being arranged on 7 both ends side wall of heat exchanger shell (heat source import) and liquid outlet 12 (thermal source outlet), be connected through 9 axle center of helical form disc and donut and with both ends tube sheet 5 Core pipe 10, several heat exchanger tubes 8 and core pipe 10 together, are divided into two groups of pipes, are connected respectively with two groups of pipes wherein being provided with an end cap 4 Logical import 2 (low-temperature receiver import) and 3 (low-temperature receiver outlets) of outlet(Wherein it is provided with two chambers in an end cap, two chambers are respectively with two Group pipe is connected, and set inlet and outlet is connected with two chambers respectively), it is particular in that along helical form annulus baffling Several piece fin a is provided with the plate face of 9 hand of spiral of plate.
The fan-shaped helical form baffling Slab element b that helical form disc and donut 9 are helically bent by several pieces is formed by connecting.
As shown in Fig. 2, fin a is vertically fixed in the plate face of helical form disc and donut 9, the surface of fin a with it is spiral The direction of the flowing of the medium of helical flow maintains an equal level on shape disc and donut 9.
As shown in Fig. 2, the fan-shaped helical form baffling Slab element b helically bent is fan-shaped for 90 degree, in this way, connecting Four fan-shaped helical form baffling Slab element b helically bent formed one it is complete spiral.
As shown in Fig. 2, the adjacent two fan-shaped helical form baffling Slab element b helically bent are fixed by rivet Come, the bottom of fin a is fixed on a riveted plating f, and riveted plating f then rivets the fan-shaped helical form folding for being fixed on and helically bending On the edge of flowing plate unit b(The riveting that riveting point is connected with the fan-shaped helical form baffling Slab element b that adjacent two helically bend Point is identical), so as to form a helical duct seamless and equipped with fin a;Helical form disc and donut 9 are wrapped in core pipe 10 On, between gap be no more than 0.5mm so that medium flows to heat source along this helical duct from heat source import 6 in tube side Outlet 12.The heat exchanger tube 8 being applied in helical form disc and donut 9 is fixedly connected with tube sheet 5, is realized by the effect of end cap 4 Flowed into low-temperature receiver import 2 and flow out the effect for reaching heat exchange from low-temperature receiver outlet 3 again.
As shown in Figure 2,3, the cross sectional shape of fin a is the fan-shaped combination that rectangle and the length of side do not wait.Fin a edge shapes For arc, it is to reduce flow resistance.
Fin a is located at the adjacent two fan-shaped helical form baffling Slab element b junctions helically bent and has two panels, and according to Secondary 1/3,5/6 punishment cloth, the effect of fin a radially on the inside of the annulus c in 9 axle center of helical form disc and donut are to disturb Stream, makes the big medium water conservancy diversion of edge flow velocity to intermediate region.
Specific fin a sizes, the height of the fin ah 11-3mm smaller than pitch or so, width between 6.5-8mm, ThicknessmBetween 2.75-3.25mm.
As shown in figure, 5,6,7, the heat exchanger tube 8 quantity on the fan-shaped helical form baffling Slab element b helically bent There are 4 kinds, be followed successively by 3,5,6 and 8.
Specifically, heat exchanger tube quantity is 3 in Fig. 4, as shown by arrows in FIG., wherein arrow is directed toward fin a arranged directions , there is arc side in the circumscribed circle center of circle of heat exchanger tube duct d centers of circle composition close to baffle plate intermediate region.Similar, other implementations The heat exchanger tube of number of cases amount, corresponding fin a arranged directions are as shown in arrow in Fig. 5,6,7.
Further, the fin a and phase radially on the inside of the annulus c in 9 axle center of helical form disc and donut 1/3 The fan-shaped helical form baffling Slab element b junctions e radial direction angles that neighbour two helically bends are between 65-72 °;It is described radially Fin a on the inside of the annulus c in 9 axle center of helical form disc and donut at 5/6 and baffle plate junction d radial directions angle between 49—61°。
As shown in Figure 4,5, 6, set at the outer ledge of the fan-shaped helical form baffling Slab element b helically bent There is pull rod to perforate g, connect steady brace to wear and fix the shape of whole helical form disc and donut 9.
