Abstract
The utility model relates to a heat exchanger, in particular to an intensified heat exchanger comprising an outer pipe and an inner pipe which is arranged in the outer pipe. The utility model is characterized in that a straight pipe and a semi-circle bent pipe is connected with each other forming the outer pipe, and the inner pipe is sheathed in the straight pipe, then two ends of the inner pipe is sealed by a sealing structure, further the straight pipes are communicated with each other through pipe pieces. One end of the outer pipe is an inlet for a first medium, and the other end of the outer pipe is an outlet for the first medium, further an inlet and an outlet for a second medium are communicated with the straight pipe.
Description
Affiliated field: the utility model relates to a kind of heat exchanger, particularly a kind of enhanced heat exchange device.
Background technology: heat exchanger is widely used in various industrial departments, is the interchangeable heat construction equipment that guarantees technological process and condition.Common structure has shell-and-tube heat exchanger and double pipe heat exchanger.The shell-and-tube heat exchanger compact conformation, unit heat transfer area metal consumption is less.Shortcoming is a complex structure, the processing request height, and the manufacturing cost height generally needs professional plant produced.The double pipe heat exchanger advantage is a simple structure, easy to process, but unit heat exchange area metal consumption is big, the use cost height.
Summary of the invention: the purpose of this utility model is a kind of simple structure of design, low, the simple enhanced heat exchange device of processing technology of cost.
The purpose of this utility model is achieved in that a kind of enhanced heat exchange device of design, and it comprises an outer tube, interior pipe is arranged in the pipe of outer tube, it is characterized in that: outer tube is fixedlyed connected with the semicircle bend pipe by straight tube and is constituted, and is with interior pipe in the straight tube, and interior pipe two ends are sealed by sealing mechanism; Be interconnected by pipe fitting between the straight tube; Outer tube one end is the import of first kind of medium, and the other end is the outlet of first kind of medium; Be communicated with inlet and second kind of media outlet of second kind of medium on the straight tube.
Described outer tube is to be connected and composed by many straight tubes and Duo Gen semicircle bend pipe, is with pipe in the 2-10 root in the every straight tube.
Pipe can be a bellows in the described little caliber.
The utility model has the advantages that: place pipe in the many little calibers in the big caliber outer tube, a kind of heat transferring medium flows at interior pipe, and another kind of heat transferring medium flows between shell.This scheme combines the advantage of shell-and-tube heat exchanger, reduces unit heat exchange area metal consumption, and simultaneously interior pipe is selected novel reinforced heat exchanger tubes such as bellows for use, has improved the unit are coefficient of heat transfer.A plurality of tube sides are connected to each other by elbow, can increase and decrease heat transfer area by the increase and decrease flexible arrangement of casing length and number of passes,, realize countercurrent flow easily.The utility model combines the advantage of double pipe heat exchanger, and inner and outer pipe can be selected existing standard series tubing for use, has reduced the workload of design and processing.The pipe medium fully mixes in the elbow, helps the raising of the coefficient of heat transfer.Improved heat exchanger unit's heat exchange area coefficient of heat transfer, reduced unit heat exchange area metal consumption, reduced design and labor content, can be widely used in each row industrial production.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Description of drawings: Fig. 1 is the utility model example structure schematic diagram.
Among the figure, 1, outer tube; 2, interior pipe; 3, outer tube flat segments; 4, elbow; 5, sealing mechanism; 6, the outlet of first kind of medium; 7, the inlet of first kind of medium; 8, the outlet of second kind of medium; 9, the inlet of second kind of medium; 10, pipe fitting.
Embodiment: as shown in Figure 1, the sealing of 2 two will be managed by sealing mechanism 5 by every section outer tube flat segments 3 places in the crooked outer tube 1 in the many little calibers; The outer tube flat segments 3 of every section bending is communicated with by pipe fitting 10; Crooked outer tube 1 one ends are as the inlet 7 of first kind of medium, and the other end is the outlet 6 of first kind of medium; On the outer tube flat segments 3 of crooked outer tube 1, be connected with inlet 9 and second kind of media outlet 8 of second kind of medium in sealing mechanism 5 inboards.
Crooked outer tube 1 is for repeatedly crooked, and number of bends is decided because of heat exchange area.What of pipe 2 are decided because of the fluid media (medium) characteristic in the many little calibers at every section outer tube flat segments 3 places.Pipe 2 can be an expansion tube in the little caliber.
Sealing mechanism 5 operated by rotary motion that seal pipe 2 in the many little calibers are at elbow 4 and outer tube flat segments 3 seam crossings, such first kind of medium enters from the inlet 7 of first kind of medium, carry out heat exchange in outer tube flat segments and second kind of medium, first kind of medium mixes at first elbow 4, enter second section straight place of outer tube again, carry out heat exchange with second kind of medium and analogize in proper order, last first kind of medium discharged through the outlet 6 of first kind of medium, finishes whole heat exchanging process.
