Description
Technical field
The utility model relates to a kind of earth source heat pump dedicated pipe, the time a kind of underground heat (cold) source that is used for utilize system to imbed the underground device that carries out heat exchange.
Background technology
Earth source heat pump is energy-conservation. environmental protection. and efficiently be well known fact.But applying of this technology is subjected to the excessive and too much limitation of well-digging rice number of one-time investment.Source, the ground heat exchanger tube of prior art mainly adopts the U-shaped pipe, according to the difference of pipe laying form, single U-shaped pipe is generally arranged, forms such as dual U-shaped pipe; By depth of burying difference be divided into shallow embedding (≤30m), in bury (31～80m) and buried (＞80m).The U-shaped cast is that the U-shaped pipe is installed in the pipe well of boring, and general pipe well diameter is 100～150mm, and well depth 10～200m, U-shaped caliber be below φ 50mm (mainly being unsuitable excessive limit of flow) generally, and present application is maximum.
Buried pipe shortcoming is that investment is big, and the cost height needs to adopt high pressure-bearing (1.6～2.0MPa) plastic tubes, rig performance requirement height; Because influenced by surface temperature very little in deep layer ground temperature field, therefore must be noted that winter caloric receptivity and summer heat exhaust balance, otherwise will influence the long-term result of use of earth source heat pump.In pipe laying between shallow, between the two buried, what plastic tube can be with common pressure-bearing type.Prior art is ubiquitous, and to imbed when underground the diameter and the degree of depth of well-digging bigger, great in constructing amount and construction speed is slow, causes the cost problem of higher.
Summary of the invention
The purpose of this utility model is to provide a kind of earth source heat pump dedicated pipe, and the diameter and the degree of depth of well-digging is bigger when underground with imbedding of solving that prior art exists, and is great in constructing amount and construction speed is slow, causes the cost problem of higher.
The technical solution of the utility model is: comprise outer tube and interior pipe, the lower end of interior pipe is stretched in the upper end of outer tube, and apart from the bottom certain distance of outer tube, the sealing of the bottom of this outer tube is sealed between the outside of the upper end of this outer tube and described interior pipe; Top at this outer tube is provided with the medium inlet, and the upper end of pipe is provided with media outlet in described.
Be equipped with ring flange in described medium inlet and media outlet.
Described outer tube adopts the noncorroding metal pipe, comprises steel-plastics composite pipe, metal composite pipe, ductile iron pipe, cylinder concrete pipe, stainless steel tube, copper pipe and aluminum pipe.
Pipe adopts the anticorrosion plastic tube in described, comprises regenerated plastics pipe, pvc pipe, PE pipe, PPR pipe and glass reinforced plastic pipe.
The upper end of described outer tube with described in adopt between the outside of pipe and solidify adhesive curing and be connected.
The upper end of pipe connects one and falls L shaped elbow in described.
The utility model has the advantages that: the structure that adopts inner and outer pipes to be nested together, dwindled radial dimension greatly, greatly reduce difficulty of construction, improved operating efficiency, reduced construction cost; Earth source heat pump well-digging rice number is reduced more than 80 percent, and the earth source heat pump one-time investment descends about 40 percent; And the technical parameter that can guarantee source, original place heat pump is constant.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of an embodiment of the utility model (not having elbow);
Fig. 2 is the sectional structure schematic diagram of another embodiment of the utility model (elbow is arranged).
The specific embodiment
Referring to Fig. 1, the utility model comprises outer tube 1 and interior pipe 2, and the lower end of interior pipe 2 is stretched in the upper end of outer tube 1, leaves the gap of certain distance between the bottom of the lower end of interior pipe 2 and outer tube, is used to flow through liquid thermal conductivity media.The bottom sealing of this outer tube 1, seal between the outside of the upper end of this outer tube 1 and described interior pipe, be provided with medium inlet 5 on the top of this outer tube 1, the upper end of pipe 2 is provided with media outlet 6 in described, is equipped with ring flange in described medium inlet 5 and media outlet 6.
Described outer tube 1 adopts the noncorroding metal pipe, comprises steel-plastics composite pipe, metal composite pipe, ductile iron pipe, cylinder concrete pipe, stainless steel tube, copper pipe and aluminum pipe.
Adopt the curing adhesive curing to be tightly connected between the outside of the upper end of described outer tube 1 and described interior pipe 2.
Referring to Fig. 2, pipe 2 upper end connects one and falls L shaped elbow 7 in described, so that the connection of different modes.
The utility model can be connected with circulation line by after arm string or the parallel connection between its medium inlet 5 and the media outlet 6 when using again.Connected mode can connect, be welded to connect with silk or flange connects, only otherwise influence down pipe get final product.Because it is intrinsic 20 percent that well depth has only, so the withstand voltage restriction of well casing reduces greatly, the expense of well-digging also reduces greatly.
The utility model in use, with being slightly less than under the utility model of earth source heat pump well head in the well of former design 20 percent well depth rice number four U type heat exchanger tubes that replace prior art to adopt.In the ground source heat pump sump, the medium inlet 5 of the other end and media outlet 6 are received respectively on the transverse tube of earth source heat pump under the lower end of outer tube 1, link to each other with the heat exchange circulating pump again, guarantee the normal operation of earth source heat pump.
Because the exchange capability of heat of buried heat exchanger tube leans on is the capacity and the flow velocity of the liquid thermal conductivity media in heat exchange area, capacity of heat transmission and the heat exchanger tube of buried heat exchanger tube.Heat exchange area of the present utility model is 1/5th of a former U type pipe, but the coefficient of heat conduction is 100 times of former U type pipe, this is because present U type pipe all adopts plastic tube, its coefficient of heat transfer is one of percentage of metal material, and the outer tube 1 that this special-purpose tubing uses is exactly a metal pipe material, as everyone knows, heat is transmitted heat by radiation, convection current and conduction.What ground pipe laying heat exchange was mainly leaned on is conduction, and the main factor of decision conduction heat exchange is exactly: 1. different medium exchange capability of heat are coefficient of heat transfer difference, even differ hundreds of times, and for example the coefficient of heat transfer of steel is 58, and the coefficient of heat transfer of plastics is 0.48.2. heat exchange area is same is directly proportional with conduction heat energy.3. the flow of heat transferring medium.4. the flow rate of liquid in the heat transferring medium.They all are directly proportional with the conduction exchange capability of heat.The temperature and the character that also have liquid in the medium, since constant, so will not discuss.And the dielectric capacity in dielectric capacity in the heat exchanger tube and the former U type pipe equates.The heat-exchange capacity of the utility model earth source heat pump dedicated pipe is about 20 times of former U type pipe exchange capability of heat like this.
