For achieving the above object, the technical solution adopted in the utility model is as follows:
The utility model is used for the underground bellows heat exchanger device of earth source heat pump heat-exchange system, be connected water jacket by underground pipe casing with well head to form, described well head connects water jacket and is provided with the mouth of a river, upper end and upper and lower connector, described underground pipe casing is set with forms by being incubated interior pipe and heat transfer corrugated outer tube, the upper and lower end of this underground pipe casing heat transfer corrugated outer tube is communicated with respectively by clip to be connected water jacket lower connector with well head connects, with bore elliposoidal sealing cap and be connected and bottom end closure; The upper connector that in the insulation of this underground pipe casing, pipe upper port is connected water jacket with well head connects; The mouth of a river, upper end that the upper port of pipe in the insulation of described underground pipe casing, well head connect water jacket respectively with outdoor circulatory system pipeline connection, realize the recuperated cycle of earth source heat pump heat-exchange system.
Described well head connects the geometric center of the upper and lower connector that water jacket is arranged on same vertical line.
In the insulation of described underground pipe casing, comparatively the conduct heat lower end of ripple heat transfer corrugated outer tube, the lower end of pipe is short, deposits blocking to prevent dirt.
In the insulation of described underground pipe casing, comparatively the conduct heat upper end of corrugated outer tube, the upper end of pipe is long, and stretches out the top of well head connection water jacket.
In described insulation, pipe is straight insulating tube.
The utility model adopts bellows underground heat-exchanger device, and water is by ripple heat transfer corrugated outer tube and surrounding soil heat exchange, and its heat transfer coefficient is far above prior art ground heat exchanger; In its insulation, pipe has relatively high heat-proof quality, has both ensured to a certain degree heat insulation, and has reduced the Heat Transfer Influence of hot short circuit, and emphasized again heat insulation not too much, and significantly improved earth source heat pump heat-exchange system underground heat exchange efficiency; The heat exchange property of the utility model bellows underground heat-exchanger device is much better than prior art ground heat exchanger, heat exchange well magnitude setting can be reduced, thus the floor space of earth source heat pump heat-exchange system can be saved, reduce initial outlay and the operating cost of earth source heat pump heat-exchange system.
