Description
Technical field
The utility model belongs to heat transfer technology field, source, ground, particularly about a kind of earth source heat pump heat exchanger.
Background technology
But ground source heat pump technology is a kind of not only heat supply of geothermal using resource but also energy-efficient air-conditioning technical that can freeze of utilizing.The theoretical foundation of heat pump comes from Carnot cycle, and is identical with refrigeration machine, according to contrary periodic duty.Because the fluctuation of annual ground temperature is little, cool in summer and warm in winter, so underground heat can distinguish in the winter time as the thermal source of heat pump heating and the low-temperature receiver of summer air-conditioning, promptly gathers heat winter from soil, supplies with indoor heating after improving temperature; From soil, gather cold summer, indoor unnecessary heat is taken out to be discharged in the ground energy go.Common earth source heat pump heat exchanger tube mounting means is divided into two kinds: a kind of is horizontal coiled pipe, promptly at the ground trench digging, imbeds heat exchanger tube, and advantage is comparatively convenient for construction, and shortcoming is that floor space is big; Another kind is a perpendicularly buried pipe, promptly imbeds heat exchanger tube at surface drilling, and advantage is that floor space is little, and shortcoming is that difficulty of construction is big slightly.Vertically the geothermal heat exchanger of pipe laying can be saved a lot of land areas than horizontal coiled pipe, therefore is more suitable for the national conditions that China has a large population in a small area.And all be to utilize single " U " shape pipe as ground heat exchanger usually in ground source heat pump technology, as shown in Figure 1, comprise input pipe, efferent duct and single " U " shape heat exchanger tube, but in actual motion, heat exchanger is buried underground, and the maintenance difficulty is big, and heat transfer rate is low and occur heat exchanger easily and stop up, in case heat exchanger stops up, entirely the heat exchange effect of source heat pump system all will be had a strong impact on.
The utility model content
It is low and occur the defective that heat exchanger stops up easily that the purpose of this utility model is to overcome in the existing earth source heat pump heat exchanger single " U " shape pipe heat transfer rate.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of earth source heat pump heat exchanger, described heat exchanger comprises input pipe 1, efferent duct 2 and heat exchanger tube, input pipe 1 and efferent duct 2 are respectively arranged with interface 7 and interface 8 at parallel position, the heat exchanger tube two ends are connected input pipe 1 and efferent duct 2 respectively by described interface 7 and interface 8, described heat exchanger tube is folded into " U " shape in the pipe laying passage 5 of soil layer 3, described heat exchanger tube adopts two " U " shape heat exchanger tubes, described two " U " shape heat exchanger tube comprises first " U " shape heat exchanger tube 4 and second " U " shape heat exchanger tube 6, and described first " U " shape heat exchanger tube 4 and second " U " shape heat exchanger tube 6 are connected in parallel between input pipe 1 and the efferent duct 2.
Described earth source heat pump heat exchanger, it is characterized in that, described input pipe 1 and input pipe 2 are provided with interface 9 and interface 10 respectively at described interface 7 and 1 meter-0.2 meter of interface 8 level intervals, and described second " U " shape heat exchanger tube is connected input pipe 1 and efferent duct 2 by interface 9 with interface 10.
Described earth source heat pump heat exchanger, level interval is 0.5 meter between described interface 7 and interface 8 and interface 9 and the interface 10.
Described earth source heat pump heat exchanger, described first " U " shape heat exchanger tube 4 and second " U " shape heat exchanger tube 6 are perpendicular to horizontal plane.
The use the beneficial effects of the utility model are:
Two " U " shapes pipe earth source heat pump heat exchangers that the utility model proposes have overcome phenomenon such as the obstruction of single " U " type heat exchanger in system, construction destructions and have caused the influence that system is moved.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Shown in figure one, a kind of earth source heat pump heat exchanger, described heat exchanger comprises input pipe (1), efferent duct (2) and heat exchanger tube, input pipe (1) and efferent duct (2) are respectively arranged with interface (7) and interface (8) at parallel position, the heat exchanger tube two ends are connected input pipe (1) and efferent duct (2) respectively by described interface (7) and interface (8), described heat exchanger tube is folded into " U " shape in the pipe laying passage (5) of soil layer (3), described heat exchanger tube adopts two " U " shape heat exchanger tubes, described two " U " shape heat exchanger tube comprises first " U " shape heat exchanger tube (4) and second " U " shape heat exchanger tube (6), and described first " U " shape heat exchanger tube (4) and second " U " shape heat exchanger tube (6) are connected in parallel between input pipe (1) and the efferent duct (2).
During construction, after soil layer (3) digs out pipe laying passage (5), perpendicular to horizontal plane, be 0.5 meter with spacing and imbed first " U " shape heat exchanger tube (4) and second " U " shape heat exchanger tube (6) abreast, when level was installed input pipe (1) and efferent duct (2), first " U " shape heat exchanger tube (4) was connected input pipe (1) and efferent duct (2) by interface (7) with interface (8); Second " U " shape heat exchanger tube is connected input pipe (1) and efferent duct (2) by interface (9) with interface (10).
Two " U " heat exchanger tubes that the utility model uses are much smaller by the probability that all stops up and destroy, and two " U " heat exchanger tube will improve about 25% than the heat exchange amount of single " U " heat exchanger tube, can improve the operational effect and the service life of earth-source hot-pump system.
The utility model is not limited to embodiment structure shown in Figure 1.As long as adopt the earth source heat pump construction and device of many " U " shape heat pipe, all drop in the protection domain of the present utility model.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
