摘要：An apparatus for achieving heat exchange between a liquid medium and theearth for insertion into a borehole in the earth, the apparatus having a casing, a capclosing the casing lower end, a dip tube of external diameter smaller than the interiordiameter of the casing and positioned within the casing providing an annular areabetween the dip tube and the interior of the casing and a top manifold cap providing afirst port connected to the upper end of casing and a second port connected to theupper end of the dip tube and flow channels within the manifold cap connecting thecasing and dip tube to flow lines so that fluid may flow downward in the dip tube andupwardly within the annular area in the casing to exchange heat with the earth. A venthole is provided to communicate with the upper end of the dip tube to prevent air lock.
