Abstract
The utility model relates to an efficient heat exchanger with double tube passes and double independent shell passes, which is designed to adapt to the working condition with large temperature difference and small flow rate. The heat exchanger is provided with U-shaped heat exchange pipe bundles which operate side by side and are arranged at intervals and a U-shaped cavity designed to facilitate the intubation, and a distribution pipe and a collecting tube are respectively arranged at the inlets and outlets of the tube passes and the shell passes. Since the shell passes of the U-shaped pipe bundles of the heat exchanger adopt an independent structure design, so that the problem of the heat conduction of a partition board is solved, and by virtue of the double-tube pass structure, the heat exchanger can not be slender, and the slenderness ratio can be kept within a reasonable range. The distribution pipe and the collecting tube can enable the fluid body to be distributed uniformly. The heat exchanger has reasonable structure, compact layout, small manufacturing difficulty and convenient installation and maintenance, and can be widely applied to the working condition with large temperature difference and small flow rate of such industries as HAV, petrification, and chemical engineering.
Description
Technical field
The utility model relates to the heat transfer technology field, is a kind of two-tube-pass and two independent shell side high-performance heat exchanger specifically, is the big temperature difference that is applied to industries such as HVAC, petrochemical industry, chemical industry, a kind of heat exchanger under the low flow rate condition.
Background technology
Under the operating mode of the big temperature difference, low discharge, always be a difficult problem for selecting for use of heat exchanger.When selecting the minor diameter heat exchanger for use, can not reach the heat exchange requirement inadequately because of heat exchange area for the requirement of satisfying low discharge and low flow velocity; If increase heat exchanger tube length, can make heat exchanger too elongated again, the scene often can't be laid; If strengthen the heat exchanger tube diameter, flow velocity is too slowed down and significantly reduce heat transfer coefficient; If change two-tube-pass bivalve journey structure into, then can make the original just very little heat transfer temperature difference in both sides become littler because of problems such as dividing plate heat conduction and a small amount of leakage currents, cause heat exchanger outlet temperature not reach requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of two-tube-pass and two independent shell side high-performance heat exchanger, and it adopts two-tube-pass and two independent shell side structure, can solve the problems of the technologies described above well.
The technical solution of the utility model is as follows:
Two-tube-pass and two independent shell side high-performance heat exchanger are provided with the U-shaped heat-exchanging tube bundle of operation side by side, the straight length outside of tube bank is equipped with housing, one end of housing all is connected with the U-shaped chamber, and the curved section of the U of tube bank all is positioned at this chamber, is provided with the dividing plate of separating the curved section of tube bank U in the chamber.The porch of heat exchanger tube side and shell side is equipped with distributing pipe, and the exit is equipped with concetrated pipe.
The utility model adopts the shell side absolute construction, can get rid of problems such as dividing plate heat conduction, makes outlet temperature reach requirement.The two-tube-pass structure that adopts makes that heat exchanger can be too not elongated, and draw ratio remains in the reasonable range.Distributing pipe and concetrated pipe are set, fluid is more evenly distributed.This heat exchanger structure rationally, layout is compact, manufacture difficulty is little, be convenient to installation and maintenance, can be widely used in HVAC, under the big temperature difference of industries such as petrochemical industry, chemical industry, the operating mode of low discharge.

The specific embodiment
1-5 further specifies the utility model with reference to the accompanying drawings:
Two-tube-pass and two independent shell side high-performance heat exchangers have two U-shaped heat-exchanging tube bundles 15 that are arranged side by side operation, at barrel-type casing 11 of the equal suit in the outside of four straight lengths of two tube banks 15;
The end of each barrel-type casing 11 is welded on the large tubesheet 14, and is connected to the U-shaped chamber 13 that makes things convenient for poling to design by chamber flange 12.Connect finish after, each is restrained 15 the curved section of U and is accommodated in the chamber 13, and is separated each other by the dividing plates 17 in the chamber 13;
At the other end welding tubule plate 10 of four barrel-type casings 11, wherein two connect tube side inlet 1 and distributing pipe 3, and two connect tube side outlet 2 and concetrated pipe 4 in addition.Offer the shell side outlet 6 of the shell side inlet 5 and the articulation set pipe 8 of connection distributing pipe 7 in the side of barrel-type casing 11;
Can be for convenience detach and maintenance, heat exchanger is fixed on the bearing made from angle steel 16.
Tube side fluid enters tube side distributing pipe 3 by tube side inlet 1, and tube side distributing pipe 3 is divided into fluid in the U-shaped tube bank 15 that two-way enters two parallel runnings respectively.Through the curved section-straight length of straight length-U, the fluid of finally getting back in 4, two tube banks of tube side concetrated pipe converges in tube side concetrated pipe 4 tube side fluid, exports 2 outflow heat exchangers by tube side at last, realizes heat transfer process at heat exchanger tube.
Shell-side fluid enters shell side distributing pipe 7 by shell side inlet 5, shell side distributing pipe 7 is divided into fluid in the barrel-type casing 11 that two-way enters two parallel connections respectively, flow in the U-shaped chamber 13 along housing 11, enter in next piece housing 11 by chamber 13 again, get back to shell side concetrated pipe 8 at last, the two-way shell-side fluid is converged in shell side concetrated pipe 8, exports 6 outflow heat exchangers by shell side at last, realizes heat transfer process.
