PURPOSE: A geothermal exchange apparatus is provided to increase the heat contact area and time of a heat exchange medium with geotherm by expanding a flow channel through which the heat exchange medium flows, thereby improving heat exchange efficiency. CONSTITUTION: A geothermal exchange apparatus includes an inlet pipe(120), a heat exchange unit(130), and a discharge pipe(140). The heat exchange unit is connected to the inlet pipe, and inserted into the earth for a heat exchange medium to exchange heat with geotherm. The heat exchange units all interconnect, and comprise unit pipes(131) which are circularly arranged to form a space which is extended vertically from the center. The discharge pipe is connected to the heat exchange unit, and discharges the heat exchange medium which is finished with exchanging heat through the heat exchange unit with geotherm.
