Description

Condensing heat conducting oil boiler radiant heating plant of floor based on the pulsating heat pipe heat transfer

Technical field

The utility model relates to the new device in floor panel heating field.

Background technology

Floor panel heating adopts water as heating agent usually, and easily fouling, higher to water quality requirement after long-play.And general feed pipe hot water temperature is at 30 ℃-60 ℃, and when main frame was out of service, the water in coil pipe will freeze cold district (as the Northeast etc.), was easy to damage coil pipe in the winter time; As do insulation, will increase investment cost.After winter heating, recirculated water must be emitted coil pipe, and is cumbersome.These descend system effectiveness, operating cost increases, management difficulty strengthens.

The utility model content

In order to solve in existing floor heating with water as the easy fouling of medium, icing deficiency, and the investment of floor heating system, operating cost are reduced as much as possible, reach energy-conservation purpose, the utility model provides a kind of heat conduction rapider evenly, reliable radiant heating plant of floor, this device not only can solve existing with the above-mentioned subject matter of water as the floor heating appearance of medium, and its heat conduction is rapider evenly, desired installing space still less, management and maintenance is the aspect more.

Technical scheme

The technical scheme that its technical problem that solves the utility model adopts is: prepared the conduction oil 10 of uniform temperature by condensing heat conducting oil boiler 1, conduction oil 10 is delivered to double pipe heat exchanger 5 through circulating pump 7 again, and double pipe heat exchanger 5 carries out heat exchange with pulsating heat pipe 8; Last pulsating heat pipe 8 imports getting in return heat into indoor by radiation floor, complete the whole transmittance process of heat.

Concrete principle is seen Fig. 1,2,3, and pulsating heat pipe radiation floor pipe laying structure figure sees Fig. 4.

Beneficial effect

The beneficial effects of the utility model are mainly reflected in the following aspects (comparing with the general floorings heating plant):

(1) Heat stability is good does not exist icing, fouling and blocking pipe problem;

(2) heat transfer efficiency is high, and the device energy conservation effect is remarkable, can save energy 20%-30%;

(3) the heat pipe heat conduction velocity is fast, the temperature controllability is strong; The floor uniformity of temperature profile;

(4) need not water treatment facilities, compact conformation, volume is little, and the installation floor space is little.

(5) condensing heat conduction oil boiler furnace body communicates with atmosphere, and is without explosion danger, safe and reliable.

(6) without the blowdown heat loss, oxygenless corrosion and caustic cracking in pot.

(7) in heat exchanger, the height of conduction oil temperature can be realized at utmost satisfying different user to the requirement of indoor floor radiation temperature 330 ℃ of following step-less adjustment.

The specific embodiment

Below in conjunction with accompanying drawing, specific works principle of the present utility model and the course of work are described further:

Fig. 1 has provided heating system schematic diagram of the present utility model, and native system comprises 3 heat exchange circulations.The 1st heat exchange circulation: after conduction oil 10 heats through condensing heat conducting oil boiler 1, the conduction oil 10 that will be heated by circulating pump 7 is transported to double pipe heat exchanger 5, by carrying out heat exchange with the pulsating heat pipe 8 that is placed in double-tube heat exchanger 5, the conduction oil of low temperature returns to condensing heat conducting oil boiler 1; The 2nd heat exchange circulation: heat-pipe medium 9 is delivered to pulsating heat pipe 8 by carrying out heat exchange with conduction oil 10 with heat; The 3rd heat exchange circulation: indoor floor mainly is delivered to heat in room air with the form of radiation by carrying out with pulsating heat pipe 8 heat that heat exchange obtains, and reaches at last the purpose of heating; During this period, the temperature of room air is controlled, and is by temperature sensor 3, temperature signal to be fed back to Temperature Setting control device 2, and compares to complete with user's design temperature.

Fig. 2 is to Fig. 1 middle sleeve formula heat exchanger 5 and pulsating heat pipe 8 signal structurally.

Fig. 3 is the specific practice of the indoor heating part of an application example of the utility model.Indoor, pulsating heat pipe 8 levels are installed on the thick polyphenyl plate heat preserving layer of 25mm, fill with the 40mm pea gravel concrete between heat pipe and be fixed, simultaneously in order to prevent the impact of expanding with heat and contract with cold of radiation floor, add zone of swelling to guarantee not arch camber of floor in the middle of whole ground, then not spalling carries out levelling by the 20mm mortar, and laying ceramic tile surface layer is gone up on the floor most.Fig. 4 is to pulsating heat pipe embodiment of the plane in the pipe laying example in radiation floor.
