Abstract
The invention discloses a novel casing type heat exchanger. A distributor is arranged in the novel casing type heat exchanger and is used for communicating a tube pass medium inlet with a plurality of U-shaped heat exchange tube inlets and uniformly distributing tube pass media entering from the tube pass medium inlet to each U-shaped heat exchange tube. The U-shaped heat exchange tubes are two or more U-shaped heat exchange tubes which are serially connected through U-shaped bends. By changing the serial-connection number of the U-shaped heat exchange tubes, tube pass length of the heat exchange tubes is increased doubly, so that the tube pass media flowing out of the U-shaped heat exchange tubes can enter the other U-shaped heat exchange tubes again, and can repeatedly circulate and return in the two or more U-shaped heat exchange tubes, and the defect of insufficient tube pass is overcome. Further, the distributor and the U-shaped heat exchange tubes are welded connectively. The novel casing type heat exchanger is good in reliability, high in heat exchange efficiency, simple in structure, easy to manufacture and convenient to mount.
Description
Technical field

In described shell and tube exchanger, medium 1 outlet 2 is communicated with by collector 7 and 9 outlets of a plurality of U-shaped heat exchanger tube.
Novel shell tubular type heat exchanger of the present invention, by medium 1 import 1, medium 1 outlet is all arranged on a cover plate, pass through distributor, collector respectively with U-shaped heat exchanger tube import, outlet is communicated with, adopt an end to coordinate a sealing gasket to seal, reduced sealing, processing and assembly difficulty, adopt distributor to carry out uniform distribution to tube side medium, especially when the tube side medium of vapour-liquid two-phase complexity, more can embody its incomparable superiority, because a lot of tube side media are when for example freon enters from the import of tube side medium, it is the liquid state that contains gas, when adopting bobbin carriage to distribute in the past, the tube side medium entering in each heat exchanger tube is inhomogeneous, but also in the U-shaped heat exchanger tube that can cause, tube side medium air content is many, in the U-shaped heat exchanger tube having, tube side medium air content is few, flow velocity is unreasonable, and the present invention distributes tube side medium by distributor, make to enter the tube side homogeneous media in U-shaped heat exchanger tube, flow velocity is reasonable, significantly improve heat exchange efficiency.
Described distributor 6 comprises the distributor body 601 with through flow hole 601a, is provided with tube side medium restriction that tube side medium to entering from tube side medium import 1 carries out throttling speed-raising, the tube side medium throttling speed-raising is broken up to the mixing portion of breaing up of mixing and by the tube side medium dispenser of breaing up mixed tube side medium and dispensing in described distributor body 601.
Described tube side medium restriction comprises the throttling stopple 601b being arranged in described through flow hole; The described mixing portion of breaing up comprises by described throttling stopple 601b and described through flow hole bottom surface and forms hybrid chamber 601c and be arranged on described through flow hole bottom surface along with the bullet 601d diminishing gradually near described throttling stopple diameter; Described tube side medium dispenser comprises the dispensing orifice 601e that a plurality of and described hybrid chamber 601c communicates, and the air line distance between described dispensing orifice 601e axis and described throttling stopple 601b axis is along with the linear or non-linear increase away from described throttling stopple 601b.
Described U-shaped heat exchanger tube 9 in described housing 10 repeatedly roundabout formation comprise " U " shape heat exchanger tube of line part and U-shaped portion.
Described collector 7 and the connection of 906 " U " type heat exchanger tube, 906 " U " type heat exchanger tube and 904 " U " type heat exchanger tube are communicated with by 905 " U " type elbow, 904 " U " type heat exchanger tube and 902 " U " type heat exchanger tube are communicated with by 903 " U " type elbow, and 902 " U " type heat exchanger tube and distributor 6 are communicated with by 901 straight tubes; Described 902,904 and 906 " U " type heat exchanger tube is connected in series by 903 and 905 " U " type elbow, forms the loop of 3 bafflings.By increasing or reduce the quantity of " U " type heat exchanger tube and " U " type elbow, change baffling number of times and tube side; Or/can, by changing caliber and the length of " U " type heat exchanger tube, adjust exchange capability of heat size.
The caliber of described 901 straight tubes and 902 " U " type heat exchanger tube is minimum, is positioned at after distributor 6, and " U " type heat exchanger tube of other serial connections is isometrical or reducing with 902 " U " type heat exchanger tube, with " U " type elbow being applicable to, is communicated with.
Because the tube side medium of vapour-liquid two-phase complexity exists phase transformation in heat transfer process, single tube side latus rectum cannot meet giving full play to of its best heat exchange property, and above-mentioned setting can effectively address this problem.(cold-producing medium is that liquid is main vapour-liquid two-phase mixture to tube side medium, in heat transfer process, continuous heat absorption evaporation due to liquid, volume expands rapidly, and tube side medium 1 is inadequate at the heat exchanger tube first half place of single latus rectum flow velocity, but too fast at the latter half of place of heat exchanger tube flow velocity, resistance increment, affected heat exchanger effectiveness, above-mentioned measure has well solved this difficult problem, has improved heat exchange efficiency.
Described deflection plate 11 is helical baffles or segmental baffle, and described deflection plate edge is provided with the shirt rim that thickness is less than described deflection plate.Shirt rim can overcome housing 10 with deflection plate due to the gap that dimensional tolerance coordinates, avoided the incidental by-pass flow of medium 2, leakage current; Guarantee that deflection plate is unlikely to unsettled in housing 10 simultaneously, avoid the vibration of " U " type heat exchanger tube, improve heat exchanger product reliability and service life, improve heat exchange efficiency.
More than explanation is only explanation of the invention, make those of ordinary skills' can completely implement this programme, but be not limitation of the present invention, those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this description, and these are all not creative modifications.But as long as within the scope of claim of the present invention, be all subject to the protection of Patent Law.
