Abstract
An apparatus for achieving heat exchange between a liquid medium and the earth for insertion into a borehole in the earth, the apparatus having a casing, a cap closing the casing lower end, a dip tube of external diameter smaller than the interior diameter of the casing and positioned within the casing providing an annular area between the dip tube and the interior of the casing and a top manifold cap providing a first port connected to the upper end of casing and a second port connected to the upper end of the dip tube and flow channels within the manifold cap connecting the casing and dip tube to flow lines so that fluid may flow downward in the dip tube and upwardly within the annular area in the casing to exchange heat with the earth. A vent hole is provided to communicate with the upper end of the dip tube to prevent air lock.
