A plurality of heat exchange blades 12 are arranged in a uniformly spaced manner around the cylindrical portion 11 and extend radially from the outer peripheral surface of the cylindrical portion 11, preferably extending through a spirally curved trajectory toward the radial direction.

The plurality of heat exchange blades 12 extend through a spiral curved path, and if based on one heat exchange blade 12, the spiral extension may enlarge a contact area with air compared to a straight extension.

An air flow passage 12a extending in the axial direction of the cylindrical portion 11 is formed between the plurality of heat exchange blades 12, and the plurality of heat exchange blades 12 are arranged in an evenly spaced manner around the cylindrical portion 11.

In order to form the air flow passage 12a as a passage extending in the axial direction of the cylindrical portion 11, a cylindrical sleeve 20 surrounding the heat exchange blades 12 is mounted along the outer edges of the plurality of heat exchange blades 12.

That is, the cylindrical tube 10 is fitted into the cylindrical sleeve 20, and the cylindrical sleeve 20 is configured to surround the heat exchange blades 12, so that the air flow passage 12a between the heat exchange blades 12 in the radial direction of the cylindrical portion 11 is blocked, thereby allowing the air to flow in the axial direction of the cylindrical portion 11.

The cylindrical portion 11 of the cylindrical barrel 10 has an accommodation space 11a so that the water 81 and the cooling body 82 can be accommodated in the accommodation space 11 a.

The rotary body 71 may be a bar magnet connected to the middle of the rotation shaft of the motor 72, or may be a bar magnet connected to both ends of a metal or synthetic resin material rod.

The stirring member 60 is structured to include a stirring body 61 having a rod shape, and an annular protrusion 62 located on the outer surface at the center of the stirring body 61.

The stirring body 61 has a rod shape with a short length, and the annular protrusion 62 is provided at the center of the stirring body 61 and contacts the upper surface of the bottom seal 50.

Therefore, the stirring body 61 is in contact with the bottom seal 50 through the annular protrusion 62, so that the contact area is small and the friction loss is small, and the stirring body can be easily rotated under the guidance of the stirring driver 70.

The horizontal annular protrusion 62 is located at the center of the upper surface of the bottom seal 50, and the annular protrusion 62 contacts the upper surface of the bottom seal 50, and the rotating body 71 of the stirring driver 70 rotates to rotate the stirring member 60 by magnetic force.

A rotating shaft pin 66 is inserted into the rotating shaft hole 64a, and the rotating shaft pin 66 is screwed into a coupling projection 68 on the upper surface of the bottom seal 50.

Therefore, the center body 64 and the inclined blades 65 can freely rotate about the rotating shaft pin 66 on the upper surface of the bottom seal 50.

Considering that the stirring member 60 is rotated at a low rotation speed in the water 81 having a great resistance, it is necessary to coordinate the stirring driver 70 by adjusting the speed of the rotating body 71 using a decelerator.
