A cold air blower for agricultural purpose

摘要

The present invention proposes a safe and efficient agricultural cooling fan. The cooling fan of the present invention includes a first heat exchange tube 28 and a second heat exchange tube 38 in which water, which is a refrigerant, is circulated and arranged in a zigzag manner, and a first cooling fin 22 installed in the first heat exchange tube to exchange heat with outside air. and the second cooling fin 32, and the first casing 20 and the second casing 30 having the first heat exchange tube and the first cooling fin installed therein, and installed on the front surface of the casing and formed on the rear surface. and a first heat exchange unit (A) and a second heat exchange unit (B) each including a first blowing fan (21) and a second blowing fan (31) capable of blowing air coming in through the vent hole to the front . The first blowing fan and the second blowing fan are connected and supported by a connecting frame 40 so as to be coaxially arranged, and both sides of the first and second casings are respectively first and second heat exchange tubes. It supports both sides of the, and the water circulated through the first heat exchange tube is characterized in that it circulates to the second heat exchange tube through the connection tube (40).
