Abstract
The utility model relates to a high-efficiency heat exchange corrugated inner sleeve underground pipe, which comprises an outer pipe, an inner pipe, underseals, a water inlet pipe joint, a water outlet joint, a corrugated pipe and a guide ring, wherein the inner pipe is arranged in the outer pipe; the underseals are arranged at the lower ends of the outer pipe and the inner pipe; the upper end of the inner pipe is connected with the water inlet pipe joint; the water outlet pipe joint is arranged on the outer wall of the outer pipe and is communicated with jackets of the inner pipe and the outer pipe; the corrugated pipe is arranged on the outer wall of the inner pipe; and the guide ring is fixedly arranged between the corrugated pipe and the outer pipe. One corrugated pipe is additionally sleeved outside the inner pipe of a common sleeve and a pearlite layer is filled between the corrugated pipe and the outer pipe to insulate heat so as to reduce heat short circuit of a medium in the jackets of the inner pipe and the outer pipe and improve heat exchange capability of the sleeve. As the medium flows through the surface of the corrugated pipe in the process of carrying out heat exchange with underground soil to generate turbulence in the flowing process so as to greatly increase heat transfer coefficient and also improve heat exchange capability of the sleeve. A normal space for fluid to flow between the corrugated pipe and the outer pipe is guaranteed by the guide ring.
Description
Technical field
The utility model relates to a kind of heat exchanger tube equipment, relates in particular to a kind of high-efficiency heat-exchange corrugated inner sleeve pipe type underground pipe.
Background technology
Ground buried pipe of ground source heat pump generally has two kinds of forms, i.e. perpendicularly buried pipe and horizontal coiled pipe.Because the horizontal coiled pipe floor space is bigger, and the heat exchange index is less than vertical tube, therefore, on engineering based on perpendicularly buried pipe.Perpendicularly buried pipe is commonly used two kinds of U type pipe and sleeve pipes, and through facts have proved, under the identical situation of equivalent caliber, the comprehensive exchange capability of heat of sleeve pipe and construction all are better than U type pipe, and therefore, more employing sleeve pipe is as underground buried tube on the engineering.At present, the inner and outer pipes of sleeve pipe great majority adopt the PVC plain tube, and the flow direction of heat transferring medium has two kinds.The one, medium interior (little) pipe from top to down, to the pipe end after again back in the chuck of interior pipe and outer tube from bottom to top, in this process from bottom to top, finish the heat exchange of medium and underground.Another is that medium is from top to bottom finished heat exchange in the chuck of interior pipe and outer tube, to the pipe end after in interior pipe from bottom to top.Though the sleeve pipe result is simple, easy construction, because there is hot short circuit phenomenon in medium in interior pipe and chuck, therefore, common double-tube heat exchanger has influenced the ability of its heat exchange because of hot short circuit phenomenon.
Summary of the invention
The technical problem that solves
The utility model provides a kind of high-efficiency heat-exchange corrugated inner sleeve pipe type underground pipe, solved the above in heat transfer process, the hot short circuit phenomenon of generation is to the exchange capability of heat of equipment problem such as exert an influence.
The utility model is the technical solution problem by the following technical programs
High-efficiency heat-exchange corrugated inner sleeve pipe type underground pipe comprises outer tube, interior pipe, underseal, water inlet pipe interface, outlet pipe interface; Pipe is arranged in the outer tube in described, and underseal is installed in the lower end of outer tube and interior pipe, the upper end of interior pipe connection water inlet pipe interface, outlet pipe interface be installed in outer tube outer wall and with its in manage and communicate with the chuck of outer tube; Also comprise bellows, the outer wall of pipe fixedly mounted guider ring between bellows and the outer tube in guider ring, described bellows were arranged in.
High-efficiency heat-exchange corrugated inner sleeve pipe type underground pipe described in the utility model also comprises thermal insulation layer, and described thermal insulation layer is filled between bellows and the interior pipe.
High-efficiency heat-exchange corrugated inner sleeve pipe type underground pipe described in the utility model, described thermal insulation layer are the perlite thermal insulation layers.
Beneficial effect
Add cover one bellows in the interior tube outside of ordinary casing, filling pearl rock stratum has been reduced medium and had hot short circuit phenomenon in interior pipe and outer tube chuck with thermal insulation between bellows and the interior pipe, has improved the exchange capability of heat of sleeve pipe.Since medium with the heat transfer process of underground in, the bellows surface of flowing through makes medium produce turbulent phenomenon in flow process, heat transfer coefficient increases greatly, the while has also been improved the exchange capability of heat of sleeve pipe.Guarantee the proper space that fluid flows by " guider ring " between bellows and the outer tube.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
High-efficiency heat-exchange corrugated inner sleeve pipe type underground pipe comprises outer tube 1, interior pipe 2, underseal 3, water inlet pipe interface 4, outlet pipe interface 5; Pipe 2 is arranged in the outer tube 1 in described, and underseal 3 is installed in the lower end of outer tube 1 and interior pipe 2, the upper end of interior pipe 2 connect water inlet pipe interface 4, outlet pipe interface 5 be installed in outer tube 1 outer wall and with its in pipe 2 communicate with the chuck of outer tube 1; Also comprise bellows 6, the outer wall of pipe 2 in guider ring 7, described bellows 6 are arranged in, fixed installation guider ring 7 between bellows 6 and the outer tube 1, thermal insulation layer 8 is filled between bellows 6 and the interior pipe 2.
As shown in Figure 3: thermal insulation layer 8 is pearl rock stratum.
The operation principle of sleeve pipe: winter is during heating operation, the medium that temperature is lower (generally being water or anti-icing fluid) by interior pipe arrive at the pipe end after from bottom to top, in the chuck of interior pipe and outer tube, absorb the heat in the underground, temperature raises, after the evaporimeter of getting back to air-conditioner host discharges heat, return the ground pipe laying and absorb heat again, circulation so repeatedly.Summer is during refrigerating operaton, the higher medium (generally being water) of temperature by interior pipe arrive at pipe at the end from bottom to top, in the chuck of interior pipe and outer tube, discharge heat and give underground, temperature descends, after getting back to the condenser absorption heat of air-conditioner host, return the ground pipe laying and relay heat, circulation so repeatedly.
