Cyclone heat exchange device and filtering system having the same

A cyclone heat exchange device comprising:

• a barrel member having two opposite end portions along an axis;
• an end cap unit including two end caps that are respectively and removably coupled to said opposite end portions, each of said end caps having two openings;
• a tube unit surrounded by said barrel member and extending along the axis, said tube unit including a first tube member and a second tube member that are respectively connected to said end caps, and an adjustment tube member that is disposed between said first tube member and said second tube member, each of said first tube member and said second tube member including a tube wall that surrounds the axis and that defines a tube space, said adjustment tube member being connected threadedly to one of said first tube member and said second tube member, being spaced apart from another one of said first tube member and said second tube member along the axis, and cooperating with said another one of said first tube member and said second tube member to define a gap therebetween, said tube unit and said barrel member cooperatively defining a vortex space therebetween,
• one of said openings of one of said end caps, said tube spaces of said first tube member and said second tube member, an inner space of said adjustment tube member, and one of said openings of another one of said end caps cooperatively defining a first flow channel,
• another one of said openings of said one of said end caps, said vortex space, and another one of said openings of said another one of said end caps cooperatively defining a second flow channel,
• said gap interconnecting said tube spaces of said first tube member and said second tube member and said vortex space;
• a ring member including a main body that surrounds the axis and that is disposed between said end cap unit and said tube unit, and a plurality of blades that are connected to an outer surface of said main body for guiding a fluid in said second flow channel to form a vortex;
• and
• a drive unit including a rotary shaft that extends rotatably along the axis through said one of said end caps, and a connecting rod that is perpendicular to the axis and that is connected to said rotary shaft and said adjustment tube member such that rotation of said rotary shaft about the axis drives said adjustment tube member to rotate about the axis relative to said another one of said first tube member and said second tube member, thereby expanding or shrinking said gap;
• wherein said barrel member, said end caps, said tube unit, said ring member, said rotary shaft and said connecting rod are made of metal.
