The shell tube heat exchanger is formed by parts of the same material through integral vacuum brazing, and has good airtightness, light mass; moreover, each part has identical thermal coefficient of expansion and low temperature resistance; meanwhile, the heat exchange flat pipe can be provided inside with different forms of heat exchange channels, and heat exchange area is greatly increased relative to round tubes under the same volume, thereby obtaining higher heat exchange density under the same volume and increasing heat exchange efficiency.
Description
Technical field
The utility model relates to the case tube heat exchanger that uses in a kind of refrigeration plant.
Background technology
Shell-tube type (or claiming shell-and-tube or shell and tube) heat exchanger is made up of cylindrical outer casing, tube sheet, tube bank and end cap.It carries out heat exchange to restrain inside and outside two kinds of fluid at differing temperatures.Settle a lot of minor diameter pipes in the shell of this traditional case tube heat exchanger, the package two ends are welded with tube sheet, and the pipe of minor diameter is welded on the tube sheet, and heat exchanger just has been divided into shell side and tube side like this.The case tube heat exchanger of some multitube journey also is provided with pass partition, and dividing plate is welded in the heat exchanger.In this case tube heat exchanger manufacture process a lot of pads are arranged, the manufacturing process complexity, so just there is the danger of leaking, and the material of weld generally is not a kind of material, because various material coefficient of thermal expansion coefficient differences, thermal stress will occur if heat exchanger is worked under big temperature fluctuation, the crack appears in weld when serious, makes heat exchanger failure.And such case tube heat exchanger is because of using the tube bank of larger cross-section on tube side, and the outer fluid contact-making surface is little in the pipe, so it is low to account for the conduction heat exchange efficiency of main heat transfer type, thereby heat transfer coefficient is lower, and volume and weight is also bigger.
Summary of the invention
The utility model purpose provides a kind of case tube heat exchanger, and it forms for each parts of commaterial carry out the overall vacuum soldering, and air-tightness is good, and each parts thermal coefficient of expansion is identical, low temperature resistant.The utility model flat heat exchange pipe is extrusion modling, and the heat exchanger channels of various ways can be arranged in the flat heat exchange pipe, under equal volume, increase with respect to the pipe heat exchange area a lot, so big, light weight of heat exchange density and heat exchange efficiency height under the equal volume.
The technical solution of the utility model is: a kind of case tube heat exchanger, comprise package, the end cap that the axial two ends of package are provided with, described package inside is provided with and a plurality of tube banks of package axially parallel and the tube sheet that is connected with described tube bank two ends, described end cap is provided with tube side import and tube side outlet, described shell is provided with shell side import and shell side outlet, also be provided with between the end cap of described homonymy and the tube sheet and be parallel to the axial baffle plate of package, described tube bank is a flat heat exchange pipe, described flat heat exchange pipe is extrusion modling, can be provided with a plurality of heat exchanger channels in it, described package is axially also arranged the axial vertical deflection plate of some roads and package.
The further technical scheme of the utility model is: a kind of case tube heat exchanger, comprise package, the end cap that the axial two ends of package are provided with, described package inside is provided with and a plurality of tube banks of package axially parallel and the tube sheet that is connected with described tube bank two ends, described end cap is provided with tube side import and tube side outlet, described shell is provided with shell side import and shell side outlet, also be provided with between the end cap of described homonymy and the tube sheet and be parallel to the axial baffle plate of package, described tube bank is a flat heat exchange pipe, described flat heat exchange pipe is extrusion modling, can be provided with a plurality of heat exchanger channels in it, described package is axially also arranged the axial vertical deflection plate of some roads and package; What each parts of described case tube heat exchanger adopted is with a kind of aluminum material.
The utility model advantage is:
1. this uses the structure of novel heat exchanging device to improve, and what each parts of described case tube heat exchanger used all is commaterial aluminium, and the place to be welded at each parts superscribes scolder, carries out the overall vacuum soldering after fixing the position, and air-tightness is good.
2. what this used novel use is that commaterial carries out the overall vacuum soldering, and thermal coefficient of expansion is identical, thus can be low temperature resistant, and prolong the service life under big temperature fluctuation environment.
3. the novel flat heat exchange pipe of this use is extrusion modling, and the heat exchanger channels of various ways can be arranged in the flat heat exchange pipe, increases much under equal volume with respect to the pipe heat exchange area, makes big, the light weight of the utility model heat exchange density under equal volume.
Description of drawings
Fig. 1 is the novel structural representation of this use;
Fig. 2 is the cutaway view of I-I direction among Fig. 1.
Wherein: the outlet of 1 tube side; 2 tube side imports; 3 end caps; 4 shell side imports; 5 packages; The outlet of 6 shell sides; 7 deflection plates; 8 tube banks; 9 baffle plates; 10 tube sheets.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as depicted in figs. 1 and 2, a kind of case tube heat exchanger, the end cap 3 that comprises package 5, package 5 axial two ends, described package 5 inside are provided with and a plurality of tube banks 8 of package 5 axially parallels and the tube sheet 10 that is connected with described tube bank 8 two ends, described end cap 3 is provided with tube side import 2 and tube side outlet 1, and described shell 5 is provided with shell side import 4 and shell side outlet 6.
Also be provided with baffle plate 9 between the end cap 3 of described homonymy and the tube sheet 10, it is divided into some compartments with the space between end cap 3 and the tube sheet 10, makes that the circulation of fluid has been divided into some tube sides in the flat heat exchange pipe, more helps heat exchange.
In order to make the fluid of shell side improve flow velocity, strengthen disturbance, on package 5 total lengths, arrange some roads deflection plate 7, baffling is carried out in the circulation of shell-side fluid, make the mobile turbulent flow that reaches of shell side, but also the length of flow of the shell side that can extend helps heat exchange, and it also plays the effect of fixing tube bank and damping well simultaneously.
Each parts of described case tube heat exchanger adopt commaterial aluminium, and the welding process of described case tube heat exchanger fixes the position then and carries out the overall vacuum soldering at first superscribing scolder at each parts place to be welded.
Described tube bank 8 is a flat heat exchange pipe, and described flat heat exchange pipe is extrusion modling, is provided with a plurality of heat exchanger channels in it and flows for fluid, so flat heat exchange pipe is bigger with respect to traditional pipe heat exchange area under equal volume, quality is lighter.
The novel air-tightness of this use is fine, and the channelling of tube side fluid and the pollution between tube side and the shell side can not take place.This use is novel to be that commaterial carries out the overall vacuum soldering owing to what use, and thermal coefficient of expansion is identical, when using under the big heat exchange environment of temperature change, very big thermal stress can not occur, has prolonged the service life of heat exchanger.Flat heat exchange pipe is extrusion modling, and the heat exchanger channels of various ways can be arranged in the flat heat exchange pipe, increase much with respect to the pipe heat exchange area under equal volume, so heat exchange density is big under the equal volume, has improved heat exchange efficiency.
