Embodiment
Refering to Fig. 1-Fig. 2, for a kind of modularization heat exchange monomer schematic diagram of one embodiment of the invention, it includes a heat exchange master
Body 10, heat exchange main body 10 are a cube, are preferably a square.The heat exchange main body 10 is provided with drilled in the form of machining
Multiple rows of first fluid through hole 20 and multiple rows of second fluid through hole 30, first fluid through hole and second fluid through hole are mutually perpendicular to and respectively
Row is staggered, in favor of fully heat exchange.The first fluid for connecting multiple first fluid through holes is additionally provided with heat exchange main body 10
Entrance bobbin carriage 21 and first fluid outlet bobbin carriage 22, the first fluid entrance bobbin carriage 21 and first fluid outlet bobbin carriage 22 can use
Approximate hemispherical bobbin carriage and it is respectively arranged with first fluid entrance 23 and first fluid outlet 24.Similarly, as second
The flow path of body, second fluid through hole 30 also have the identical structure design of a first fluid through hole, connect multiple second fluids and lead to
Second fluid entrance bobbin carriage 31 and first fluid the outlet bobbin carriage 32 in hole, the second fluid entrance bobbin carriage 31 and second fluid bobbin carriage
32 are respectively arranged with second fluid entrance 33 and second fluid outlet 34.
Refering to Fig. 3 A-3B, for the flow path schematic diagram of the heat exchange monomer of the embodiment of the present invention one, first fluid/second fluid
Respectively from first/second fluid inlet after first/second fluid inlet bobbin carriage enters multiple first/second fluid through-holes, then
Exported and flowed out by first fluid through first/second fluid outlet bobbin carriage.First fluid and second fluid carry out in heat exchange main body
Sufficient heat exchange.
The present invention cancels the tube sheet of traditional heat exchangers, ensures that first fluid through hole and second fluid through hole are thorough with machining
Isolation, solves the leakage problem of traditional heat exchangers tube sheet junction.
Refering to Fig. 4, for a kind of heat exchanger being composed in series by multiple heat exchange monomers 1 of the present invention, it is carrying out concatenation, it is preceding
The outlet of the first fluid of one heat exchange monomer is connected with the import of the first fluid of adjacent rear heat exchange monomer, second fluid
Flow path connection mode also in this way, calculate the quantity of required heat exchange monomer according to demand.
In the place that some places are restricted, can still freely form adaptation using the heat exchange monomer of the present invention makes
With the heat exchanger in place, refering to Fig. 5, Fig. 6, multiple rows of heat exchanger arranged side by side, bypass barrier can be combined into.
In fact, those skilled in the art can be according to the general knowledge of grasp, by the heat exchanger of the present invention and traditional fixation
Formula tubular sheet heat exchanger is contrasted.Assuming that both overall lengths are all 3960mm, cross-sectional shape size substantially 500mm*700mm, the
The bore size of one fluid flowing path is 19mm, both heat exchange areas calculate as follows：
The present invention heat exchange area be：19*π*14*7*2*360*10≈42.1 m2。
The heat exchange area of traditional heat exchangers is：According to maximum piping mode, tube spacing 25mm, the cloth in the cylinder of DN500
Pipe 307, its heat exchange area are：19*π*2851*307≈52.2 m2。
From data above, traditional heat exchangers only tube-to-tubesheet joint just has 307*2=614, and this very strong is changed
Hot device only needs to be mutually butted connector 9*2*2*4=144 between adapter, and the risk leaked reduces（614-144）/614
=76.5%, moreover, both simply slightly have gap on heat transfer area；Meanwhile without baffle plate, pull rod, gear pipe/bar, impingement baffle
Etc. various internals, also without issuable fluid vibration risk；Finally, due to new construction is simply by different loose patterns
Block and connecting flange are formed, also just without various parts such as the vessel flanges, end socket, tube sheet of traditional form, easy to purchase system
Make.
Further, modular heat exchange monomer of the invention is easy to repair.If traditional heat exchangers are let out using rear discovery
Leakage, generally takes the form of plugging, but if plugging repeatedly, will influence heat transfer efficiency.And modular heat exchange monomer, once
It was found that situations such as leakage, it is only necessary to replace single component.Modularization monomer is easy to manufacture, transport.Since monomer almost shapes
Product, needs Optional assembling by client.So will be significantly due to non-shaped product on the manufacturing cycle.Usually can also be according to production
Energy equilibrium condition production, once in need just can assemble delivery rapidly, reduces the manufacturing cycle.
Only as described above, be only the preferred embodiments of the invention, when cannot with restrictions the present invention implementation model
Enclose；The equivalent changes and modifications made generally according to the scope of the claims of the present invention, should all be still covered by the present invention within the scope of the patent.
