1. A heat exchange device comprising:
a barrel including two end portions opposite along an axis;
a cap unit including two end caps detachably and respectively connected to said end portions, each of said end caps having two openings spaced apart from each other;
a heat exchanger disposed in said barrel and between said end caps, and including two conduit members spaced apart from each other along the axis by a gap, each of said conduit members including a surrounding wall that extends along the axis and that defines a passage therein, and a plurality of fins that extend radially from said surrounding wall, said heat exchanger cooperating with said barrel to define a vortex chamber therebetween, said passages of said conduit members cooperating with one of said openings of each of said end caps to define a first flow channel adapted to permit fluid to flow therethrough, said vortex chamber cooperating with the other one of said openings of each of said end caps to define a second flow channel adapted to permit fluid to flow therethrough, said fins being adapted to conduct heat exchange with the fluid flowing through said first flow channel and said second flow channel;
an annular vortex generating member surrounding the axis, mounted between said barrel and said heat exchanger, and including a plurality of blades that are formed at an outer surface thereof and that are adapted to guide the fluid in said second flow channel to generate a vortex;
a condensing unit mounted to one of said end caps of said cap unit and including a cooling chip module that includes a heat absorbing plate disposed at an end of said cooling chip module proximate to the one of said end caps and adapted for absorbing heat of the fluid, and a heat dissipating plate disposed at an end of said cooling chip module distal from the one of said end caps along the axis and adapted to dissipate heat absorbed by said heat absorbing plate; and
an electric unit mounted to the other one of said end caps of said cap unit and including a motor, an internal threaded sleeve that is driven by said motor to rotate, and an external threaded shaft that threadedly engages and is driven by said internal threaded sleeve to move along the axis when said internal threaded sleeve is rotated, and that is co-movable with at least a portion of one of said conduit members such that said portion of said one of said conduit members is movable relative to the other one of said conduit members along the axis to adjust a dimension of said gap along the axis.
