Coordinate, unit mm) with heat exchange efficiency (right side ordinate) and fluid runner internal resistance (left side ordinate, unit Pa) it
Between relationship schematic diagram.Wherein, as shown in Figure 1, for the first basement membrane of (as symmetrical) hexagon, α can be 5*
10-5, β can be that 0.0849, γ can be 50.182.Therefore, curve B is to fit η=(α L2+ β L+ γ)/V curve, wherein V
For fluid flow rate, general range is in 0.5m/s~1.5m/s, preferably in 1m/s or so (V=1m/s under operating mode corresponding to Fig. 1
