The specific embodiment
Below by the specific embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of shell-and-tube heat exchanger, it comprises housing 1 and two groups of heat-exchanging tube bundles 2 that are arranged at respectively two ends in the described housing, wherein, described housing 1 two ends are respectively arranged with two tube side interfaces 5, the two ends of every group of described heat-exchanging tube bundle 2 are communicated with respectively wherein two described tube side interfaces 5 of an end of described housing 1, and described housing two ends are respectively arranged with a shell side interface 3.The benefit of doing like this is, described shell-and-tube heat exchanger can be realized segmentation heat-obtaining and cooling or the specific functions such as segmentation heat-obtaining or different medium segmentation cooling, and two heat exchangers of unnecessary use are saved the space, the simplification system, and also more convenient to use.
Be set with one section guide shell 4 in the described housing 1, the corresponding described shell side interface 3 of the barrel of described guide shell 4 arranges, and described guide shell 4 consists of the chuck flow-guiding structure with described housing 1.Described guide shell 4 is connected with described housing 1 inner wall sealing near an end at described housing 1 middle part, described guide shell 4 is angle away from an end port at described housing 1 middle part, described angle from described guide shell 4 near the described guide shell 4 of a side direction of described shell side interfaces 3 lopsidedness away from described shell side interface 3, that is, a side length of described guide shell 4 close described shell side interfaces 3 is less than the side length of described guide shell 4 away from described shell side interface 3.The diameter of described housing 1 and described guide shell 4 corresponding positions is greater than the diameter at described housing 1 other position, and the diameter at described housing 1 other position is identical with the diameter of described guide shell 4.The benefit of doing like this is: 1, guide shell 4 is set can prevents that not only the porch high-velocity fluid is to the direct impact of tube bank, and can make the shell side longitudinal stream fluid that enters housing reach even distribution, thereby the heat transfer area of shell side inducer tube bank is fully used, in addition, can reduce the heat transfer dead band, prevent the flow-induced vibration that inducer may occur; 2, gas enters housing before along the rotational flow of guide shell outer wall, under centrifugal action, partial impurities is separated, and then be got rid of, and has reached the effect of Purge gas; This structure along the different shortcoming of axial fluid resistance, makes most of medium enter interbank fluid resistance identical, thereby makes fluid can enter more uniformly shell side when 3, can also overcome the existing medium of isometric cylindrical shape guiding device and enters shell side.
The deflection bar type tube bank that described heat-exchanging tube bundle is comprised of the U-shaped pipe, described U-shaped tube outer surface is provided with polytetrafluorethylecoatings coatings.The advantage of polytetrafluorethylecoatings coatings is: 1, the thermal conductivity factor of this coating almost equates with stainless steel, and heat-transfer effect is good; 2, polytetrafluoroethylene (PTFE) has good hydrophobicity, thereby destroys the formation of moisture film, has improved heat transfer efficiency; 3, polytetrafluoroethylene (PTFE) character is highly stable and not perishable, and greasy dirt and dust also should not adhere to, and avoid coking; 4, PTFE anti-wear is good, is easy to clear up and can increase the service life, and technique is simple simultaneously, cost is also lower, heat-transfer effect is also relatively good, ripe theory analysis and application foundation has also been arranged, so the cost performance of this heat exchanger is higher in the research of heat exchanger coating.
Described housing 1 both ends are provided with respectively a tube sheet 6, described tube sheet 6 is slit into a bobbin carriage 7 with described housing 1 end parts, and the two ends of every group of described heat-exchanging tube bundle 2 are communicated with wherein two described tube side interfaces 5 of an end of described housing 1 by corresponding with it described bobbin carriage 7.Described heat-exchanging tube bundle 2 is connected on the described tube sheet 6, and described tube sheet 6 plays the effect of fixing described heat-exchanging tube bundle 2, makes its arrangement evenly not mixed and disorderly; Because the terminal aperture of described heat-exchanging tube bundle 2 is more, therefore adopt the end of described heat-exchanging tube bundle 2 to be communicated with the mode of described tube side interface 5 by described bobbin carriage 7, refrigerants in the described heat-exchanging tube bundle 2 converge and flow out through described tube side interface 5 after entering described bobbin carriage 7 again, install and use all convenient.
Be provided with main dividing plate 8 in the described housing 1, offer thermal hole or breach on the described main dividing plate 8, described main dividing plate 8 is arranged between two groups of described heat-exchanging tube bundles 2.Be provided with in the described housing 1 and be no less than two secondary dividing plates 9, offer through hole or breach on the described secondary dividing plate 9, be provided with on every group of described heat-exchanging tube bundle 2 and be no less than a described secondary dividing plate 9.Described main dividing plate 8 and described secondary dividing plate 9 play the effect of buffer fluid, so that fluid rests on the time of shell side 1 is more of a specified duration, with described heat-exchanging tube bundle 2 abundant heat exchange.
Make for the ease of installing, with described housing 1 piecemeal manufacturing, described housing 1 comprises left end socket, left shell, right shell body and the right end socket that is connected in turn by flange 10, in described left end socket and the described right end socket described bobbin carriage is set, described housing is divided into left shell and right shell body from the centre, two groups of described heat-exchanging tube bundles are arranged at respectively in the described left shell and in the described right shell body, described main dividing plate 8 is arranged at described left and right housing junction.
The course of work: in the system that needs heat-obtaining and cooling, described heat-obtaining medium enters from left tube side import, then enters described heat-exchanging tube bundle by described bobbin carriage, with the fluid heat transfer that flows into from the shell side import in the described left shell, flows out from left tube side outlet again; Flow to described right shell body behind the abundant heat-obtaining of described fluid process left shell, described cooling media enters from right tube side import, enter described heat-exchanging tube bundle by described bobbin carriage, with the fluid heat transfer in the described right shell body, flow out from right tube side outlet again, fluid through abundant heat-obtaining and cooling flows out by the shell side outlet, finishes the work.
In the system that needs the segmentation heat-obtaining, the described heat-exchanging tube bundle of the media flow of high temperature heat-obtaining in described left shell, the described heat-exchanging tube bundle of the media flow of low temperature heat-obtaining in described right shell body.
In the system of the different medium segmentation coolings of needs, the described heat-exchanging tube bundle of a kind of media flow in described left shell, the described heat-exchanging tube bundle of another kind of media flow in described right shell body.
Should be noted that the described fluid of the present embodiment flows from left to right for ease of the explanation workflow, each import and outlet can correspondingly be exchanged in other embodiments.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
