Fluid dynamic rain-making apparatus

A fluid dynamic rain-making apparatus, comprising:

• a first tubular member (10), comprising a fluid channel (11), the fluid channel (11) comprising a first opening (12) and a second opening (13) defined on two ends thereof respectively, and an axial cross section of the fluid channel (11) decreasing along a direction from the first opening (12) toward the second opening (13);
• and
• a thermal conductor (20), comprising a second tubular member (21) and a plurality of heat sinks (22) circumferentially arranged on an outer surface of the second tubular member (21), the second tubular member (21) attached to the second opening (13) of the first tubular member (10);
• wherein a fluid (A) enters the fluid channel (11) from the first opening (12) to be a cooled fluid (A1) after acceleratedly flowing through the fluid channel (11), and the cooled fluid (A1) cools the second tubular member (21) while flowing through the second tubular member (21) to make a temperature of each one of the heat sinks (22) be lower than a temperature of the fluid (A) at an external of the thermal conductor (20).
