Third channel, the medium larger for the flow that circulates, so as to when cold and hot both sides flow differs larger, not influence pressure-bearing energy
On the premise of power, heat transfer efficiency can be improved, reduces the overall cost of heat exchanger.For example, during steam-water heat exchanging operating mode, vapour sidles
Triple channel, beneficial to condensation, water walks first passage and/or second channel, and flow velocity is high, so that overall heat transfer coefficient improves.
With reference in a first aspect, in a kind of possible implementation of first aspect, the shell-and-plate plate is using unidirectional
Oblique ripple structure, ripple and horizontal direction angle are 25 degree.
In this programme, angle is that both 25 degree of resistance drops and heat transfer efficiency can reach preferable balance；Angle angle
Excessive, although heat-transfer effect is preferable, resistance drop is big；And angle angle too small, although resistance drop is small, heat-transfer effect phase
To poor.
Second aspect provides a kind of shell-and-plate plate beam, including multiple plates being mutually inverted in the above-mentioned technical proposal stacked
Shell-type plate, adjacent shell-and-plate plate upset stacking form three kinds of passages of various cross-sectional areas after being welded to each other：First passage,
Second channel and third channel.Further, the area of section of third channel is more than first passage, the area of section of first passage
More than second channel.
With reference to second aspect, in a kind of possible implementation of second aspect, the flow cross-section areas of third channel
For 2-4 times of first passage and the flow cross-section areas sum of second channel.
In this programme, area of section and the first passage and second channel area of section sum of third channel are in 2-4
Times when, its applicability is preferable, and heat transfer efficiency is high；During more than 4 times, preferable sealing is not easily accomplished between adjacent plate；It is and low
When 2 times, its heat transfer efficiency is relatively low under the operating mode that heat exchanger both sides flow differs larger.
With reference to second aspect or above-mentioned some possible embodiments, in a kind of possible implementation of second aspect
In, it is described to be tightly connected as welding.
The third aspect provides a kind of lamella heat exchanger, including the shell-and-plate plate beam described in any of the above-described scheme, institute
State first passage and second channel is used for the low discharge medium that circulates, third channel is used for the big flow medium that circulates.
In this programme, the heat transfer efficiency of lamella heat exchanger is high, and overall cost is low, and less scaling, and flow resistance is small,
Heat resisting and pressure resisting performance is good, saves the energy.
