Fig. 9 is the cross-sectional view vertical with length direction of the ice-making disc 11 of the ice maker 10 of Fig. 4.Fig. 9, which is shown, includes
The section of upper pipe 13a, side ducts 14a and driving portion 12.According to the short transverse ruler in the section of upper pipe 13a
Very little h1With width direction size W1, the equivalent diameter d of upper pipe 13a1Pass through d1=(h1×W1)/(2h1+2W1) and find out.Together
Sample, the equivalent diameter d of side ducts 14a2Also according to the short transverse size h of side ducts 14a2With width direction size W2, lead to
Cross d2=(h2×W2)/(2h2+2W2) and find out.The pressure loss and equivalent diameter d of fluid in usual pipeline1It is inversely proportional.I.e.
The pressure reduction of the fluid flowed in pipeline if equivalent diameter d1 becomes smaller.If the pressure of the fluid in pipeline is because of the pressure loss
And reduce, then the flow of the fluid in pipeline is reduced.In addition, equivalent diameter d is in upper pipe 13a and side ducts 14a
The area of the section vertical with the direction that cold air is flowed become the smallest part and calculate.
In the ice maker 10 of embodiment 1, the equivalent diameter d of upper pipe 13a1It is more equivalent than side ducts 14a
Diameter d2It is small.Thus to the amount Q of the side ducts 14a cold air flowed2Become the amount Q of the cold air than flowing to upper pipe 13a1
It is more.Therefore, in the case where generating the heat exchange of cold air and surrounding air, compared with the cold air flowed in side ducts 14a,
The temperature rising of the cold air flowed in the small upper pipe 13a of thermal capacity becomes faster.If air themperature is set as t, using e as water
Vapour pressure and using P as atmospheric pressure then finds out air by ρ=1.293 × P/ (1+t/273.15) × (1-0.378e/P)
