Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of heat exchanger 100, including bobbin carriage 10, tube sheet 20, more piece are mutual Shell-side cylinder 30, multiple heat exchanger tubes 40 and multiple tube side elbows 50 disposed in parallel.Every two sections shell-side cylinder 30 passes through one Tube side elbow 50, which is connected, makes multiple shell-side cylinders 30 successively join end to end.The quantity of bobbin carriage 10 is two and is individually fixed in more piece One end of the corresponding two sections shell-side cylinder 30 of the head end and tail end of shell-side cylinder 30.Each bobbin carriage 10 is equipped with tube side adapter tube 11, It is flowed in or out for tube side medium;It is additionally provided with positioned at the side of two section shell-side cylinders 30 of head end and tail end close to adjacent bobbin carriage 10 shell side adapter tube 31, flows in or out for shell side medium.
Specifically, tube sheet 20 includes the front tube sheet 21 and back tube sheet 22 for being individually fixed in every 30 both ends of section shell-side cylinder.Often By close to tube side elbow 50 and the connecting tube between front tube sheet 21 and back tube sheet 22 between two adjacent sections shell-side cylinder 30 60 connections, so as to form the flow channel of shell side medium in shell-side cylinder 30, connecting tube 60, and save arrangement space.
Multiple successively interval and the baffle plates between front tube sheet 21 and back tube sheet 22 are equipped in every section shell-side cylinder 30 32, multiple heat exchanger tubes 40 are respectively arranged in every section shell-side cylinder 30 and run through baffle plate 32, front tube sheet 21 and back tube sheet 22 and will Bobbin carriage 10 is connected to tube side elbow 50, so that the flowing for forming tube side medium in bobbin carriage 10, heat exchanger tube 40, tube side elbow 50 is logical Road.Specifically, one of bobbin carriage 10 is used to the tube side homogeneous media of inflow being distributed to each heat exchanger tube 40, another bobbin carriage 10 send out for the tube side medium in heat exchanger tube 40 to be collected another rise, and have sealing between usual tube sheet 20 and heat exchanger tube 40, prevent Only shell side medium and the mixing of tube side medium.
Further, every two sections shell-side cylinder 30 and the tube side elbow 50 between two section shell-side cylinders 30 form " U " Type structure;Multiple heat exchanger tubes 40 are parallel to each other and are multiple rows of arrangement in the short transverse of heat exchanger tube 40, adjacent two rows heat exchanger tube 40 interlaced arrangements offer the through-hole passed perpendicularly through for heat exchanger tube 40 on each baffle plate 32.
Preferably, baffle plate 32 has an arcuate indentation, the notch of multiple baffle plates 32 using single segmental baffle Short transverse along shell-side cylinder 30 is arranged in a staggered manner in upper and lower or left and right, is formed so that baffle plate 32 is mounted in shell-side cylinder 30 The flow channel of detour, to enhance heat transfer effect.
In present embodiment, the quantity of shell-side cylinder 30 is four sections, and shell-side cylinder 30 is in straight cylindrical and uses seamless steel Pipe is made, and manufacturing process is simple.Further, the quantity of tube side elbow 50 is three and is in hollow cylindrical, tube side elbow 50 Bending angle be 90 °, be conducive to reduce shell-side cylinder 30 thermal (temperature difference) stress;It is corresponding, the quantity of connecting tube 60 be three and In straight cylindrical, while connecting tube 60 can also be used to the shell-side cylinder 30 for supporting two sections to be connected, and make two section shell-side cylinders 30 Between be more uniformly stressed.
Preferably, bobbin carriage 10 is welded and fixed with tube sheet 20, and bobbin carriage 10 is close by channel flange 12 away from the side of tube sheet 20 Envelope.
Preferably, the by-pass damper 33 and pull rod 34 for baffle plate 32 to be fixedly mounted are additionally provided in shell-side cylinder 30.This In embodiment, pull rod 34 is set to the outer rim of multiple heat exchanger tubes 40 in pairs, and baffle plate 32 is welded on pull rod 34, therefore is not needed often Distance sink tube;By-pass damper 33 is made of thick steel plate or band steel, is then inserted into simultaneously spot welding in the slot that baffle plate 32 opens up On each baffle plate 32, the mistake to prevent shell side medium short circuit in shell-side cylinder 30 influences heat transfer effect.
Also referring to Fig. 3 and Fig. 4, the outside of shell-side cylinder 30 is provided with support frame 70, and support frame 30 is frame-type knot Structure and including fixing end 71 and sliding end 72.The support frame 70 is welded to form by fashioned iron to be fixed in ground or equipment, with enhancing Stability in operational process.In present embodiment, two bobbin carriages 20 are set to the same of more piece shell-side cylinder 30 arranged in parallel End, fixing end 71 are arranged close to bobbin carriage 20.
The heat exchanger 100 provided in present embodiment is horizontal heat exchanger, and shell side medium bottom in and top out, tube side medium is enterprising Lower through too long path transmission, the depth that can be realized between tube side medium and shell side medium exchanges heat out, changes compared to fixed tube sheet The heat transfer effect of hot device and U-tube heat exchanger is more preferable, and when one timing of flow, number of passes is more, and heat transfer coefficient is bigger, more has to heat transfer Benefit.
Heat exchanger 100 provided by the utility model is gone here and there more piece shell-side cylinder 30 by tube side elbow 50 and connecting tube 60 Connection realizes multitube distance muitishell function, while the flow direction of tube side medium can be realized in the whole complete phase of flow direction with shell side medium Instead, heat exchange efficiency with higher;And structure is simple, is conducive to the diameter for reducing shell-side cylinder 30, and then improve shell side medium Flow rate;Setting dividing plate is not needed, processing cost is reduced, is avoided because leakage failure brings heat exchange property to fail Risk, be conducive to enhance equipment stability and heat exchange property.
The utility model is not only in the description and the implementation described, therefore for the personnel of familiar field For other advantage and modification is easily implemented, therefore without departing substantially from universal defined by claim and equivalency range Spirit and scope in the case where, the utility model is not limited to specific details, representative equipment and shown here as with retouch The diagram example stated.
