The top being welded in housing 8, and opening is being offered around the one end of flowing plate 18 away from its breach, the opening, which runs through, to stream
Plate 18, the effect of opening are that it can avoid gas from hovering here and form flow dead.
In this way, deflection plate 19 and around flowing plate 18 be collectively forming wriggle extension runner for air flow.
It should be noted that when the quantity of deflection plate 19 is even number, around the bearing of trend of flowing plate 18 and adjacent two
The bearing of trend of deflection plate 19 is on the contrary, when the quantity of deflection plate 19 is odd number, around the bearing of trend of flowing plate 18 and one of them
The bearing of trend of deflection plate 19 is identical, and the bearing of trend with another deflection plate 19 this manner it is also possible to form and wriggle on the contrary, prolong
The runner stretched.
To sum up, the tandem U-tube heat exchanger is rational in infrastructure, and its heat exchange efficiency is high, and the heat exchange energy consumption of system is relatively low, favorably
In cost and the floor space of reducing investment outlay.
