Abstract

The utility model relates to a flow-guiding cooling apparatus which comprises an inner barrel body (3), an outer barrel body (2), a cover plate (7) and a spiral coil pipe (4) positioned between the inner and the outer barrel bodies (3), (2), wherein the upper end of the outer barrel body (2) is fixedly connected with a flange (5), and the lower end of the outer barrel body (2) is fixedly provided with a bottom plate (1) on which a cooling water inlet (13) is arranged; the cover plate (7) is installed on the upper end surface of the flange (5), and a cooling water outlet (9) is arranged on the cover plate (7) which is also provided with a sample inlet pipe (11) and a sample outlet pipe (10) which are both communicated with the spiral coil pipe (4); the outer wall of the inner barrel body (3) or the inner wall of the outer barrel body (2) forms a spiral groove shape. The utility model has the advantages of convenient disassembly, long flowing line of cooling water, high heat exchanging efficiency, long service life, good sealing performance, wide application range and no scale formation.

Description

The flow-guiding type cooler

Technical field

The utility model relates to a kind of heat-exchange device of therrmodynamic system, particularly a kind of flow-guiding type cooler.

Background technology

Working media that circulates in thermal power generation or heating system such as water, vapor (steam) temperature are very high, for these working medias of online detection, need cool off by sample water, the steam of analysis meter being about to, thereby adopt cooler.People have adopted the laminar flow formula cooler of being made up of inner barrel, outer cylinder body and coil pipe in the prior art, there is the gap in this cooler between outer cylinder body, inner barrel and coil pipe, therefore in the clearance channel of this cooler, form laminar flow, the cooling-water flow path is short, film-cooled heat is little, and heat exchange efficiency is low.

Summary of the invention

The purpose of this utility model provides the high flow-guiding type cooler of a kind of heat exchange efficiency.

The technical scheme that realizes above-mentioned purpose is: a kind of flow-guiding type cooler, comprise inner barrel, outer cylinder body, cover plate and the spiral coil between inside and outside cylindrical shell, the upper end of outer cylinder body is fixedly connected with flange, the lower end of outer cylinder body is fixed with base plate, has cooling water inlet on the base plate, cover plate is installed in the upper surface of flange, cover plate is provided with coolant outlet, and sample inlet pipe and sample are housed pipe, and sample inlet pipe and sample go out the Guan Junyu spiral coil and communicate, and the outer wall of inner barrel or the inwall of outer cylinder body be flute profile in the shape of a spiral.

After adopting technique scheme, because the inwall of outer cylinder body or the outer wall of inner barrel be flute profile in the shape of a spiral, coil pipe can place in the helicla flute, after cooling water enters cooler, can only flow along the helicla flute of outer cylinder body inwall or inner barrel outer wall, increased flow path, do not increasing the cold fluid flow and do not reducing under the prerequisite of cooling fluid temperature, improve the utilization ratio of cooling water greatly, thereby improved the heat exchanger effectiveness of cooler.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～3, a kind of flow-guiding type cooler, comprise inner barrel 3, outer cylinder body 2, cover plate 7 and being positioned at, outer cylinder body 3, spiral coil 4 between 2, enclosed baffle is equipped with in the inside of inner barrel 3, the upper end of outer cylinder body 2 is fixedly connected with flange 5, the lower end of outer cylinder body 2 is fixed with base plate 1, has cooling water inlet 13 on the base plate 1, cover plate 7 is installed in the upper surface of flange 5, cover plate 7 is provided with coolant outlet 9, and sample inlet pipe 11 and sample are housed pipe 10, and sample inlet pipe 11 and sample go out pipe 10 and all communicate with spiral coil 4, and the outer wall of inner barrel 3 is flute profile in the shape of a spiral.Also can shown in Fig. 4,5, the inwall of outer cylinder body 2 be made the spiral flute profile, and the outer wall of inner barrel 3 is made the light wall, also can reach same effect.

As shown in Figure 1, outer cylinder body 2 and adpting flange 5 welding are provided with the sealing gasket 6 of high temperature high voltage resistant between adpting flange 5 and the cover plate 7, and with bolt 8 adpting flanges 5 and cover plates 7.Unclamp set bolt 8, outer cylinder body 2 can be for convenience detach, so that clean the dirt in the cooling cylinder.

As shown in Figure 1, base plate 1 is provided with a drain screw 12, so that when stopping using, can put the water in the clean cooler.

As shown in Figure 1, during the utility model work, cooling water enters in the outer cylinder body 2 from water inlet 13, and is mobile from bottom to top along the helicla flute 14 of inner barrel 3 outer walls, coolant outlet from the cover plate 79 flows out at last, and sample goes out pipe 10 from sample from sample inlet pipe 11 again through spiral coil 4 and flows out.

The utility model flow of cooling water circuit is long, the heat exchange efficiency height, and the life-span is long, and good seal performance is less scaling, applied range.
