Description

Passive energy storage and supply system with vibration enhanced heat transfer function

Technical Field

The utility model relates to a stride season energy storage technical field, in particular to passive form with vibration intensification heat transfer function strides season collection energy storage energy supply system.

Background

A traditional cross-season pipe laying energy storage system (BTES) comprises a large number of drilling holes, filling materials, pipe laying heat exchangers (single U pipes, double U pipes and other special pipes), circulating fluid, water collecting and distributing devices, water pumps and the like. In the whole operating year, the BTES needs to firstly drive a circulating fluid (water) to flow through a cold and heat source collecting device (energy collection) by a water pump in the energy storage season and flow through an underground energy storage body again to inject collected cold/heat energy (energy storage), and then extract the cold/heat energy collected in the energy storage season from the underground energy storage body by using the same heat exchange means in the energy utilization season and supply the cold/heat energy to a building for use (energy supply). Therefore, the traditional BTES essentially belongs to an active sensible heat exchange system, and not only consumes a large amount of water pump conveying power consumption in the energy collection, energy storage and energy supply stages, but also the energy collection, energy storage and energy supply efficiency of the whole system is low. Energy collection aspect: taking an energy collecting plate as an example of a cold/heat source, since the energy collecting efficiency of a source end is related to the installation angle, the ambient temperature, the wind speed and the sky radiation angle, and the energy collecting plate is usually fixedly installed, the heat collecting efficiency in summer and the cold collecting efficiency in winter of the traditional energy collecting plate can not be always kept optimal due to real-time changes of environmental factors. In contrast, although researchers propose a scheme that the relevant energy collecting plate can be adjusted along with the change of external factors ("pursuit best"), the system design is complex, the modularization degree is low, and meanwhile, large-scale popularization is difficult due to high construction cost and difficult maintenance. Energy storage and supply aspects: because the traditional BTES still belongs to the sensible heat exchange process in the energy storage and energy supply processes, the operation performance of the whole system has to be maintained by increasing the number of well groups in practical engineering, which further causes the high construction cost and seriously affects the popularization and application of the BTES. In addition, excessive well digging and unreasonable construction will also cause irreversible ecological damage to the underground soil and water environment. In order to improve the energy storage and supply efficiency, reduce the construction cost and influence the surrounding underground ecological environment, technicians mainly adopt double U pipes or other special pipes to replace single U pipes so as to improve the heat exchange capacity per linear meter. This approach helps to reduce the number of wells and the amount of ancillary equipment, but other problems follow. For example, double U-tubes/profile tubes are prone to deformation during drilling and tube lowering processes, so that the double U-tubes/profile tubes are attached to each other (commonly referred to as "short circuit"), and a buried tube part below the short circuit point or even all of the buried tube part fails, so that the actual available capacity of the whole BTES is greatly deviated from the designed value. In addition, the backfill of the filler can also cause the uneven backfill phenomenon due to different drilling conditions and random backfill operation, so that the heat diffusion coefficients and the heat exchange efficiency of the drill holes at different positions are different, and the fine management of the BTES heat storage/extraction process is not facilitated. Therefore, the above drawbacks of conventional active BTES have become a difficult engineering problem to be solved by those skilled in the art.

The utility model discloses passive energy collection energy storage energy supply system with vibration enhanced heat transfer function can be used for summer thermal-arrest heat accumulation and winter heat supply mode, perhaps is used for winter cold collection cold-storage and summer cold supply mode.

Summer heat collection and storage and winter heat supply modes: in summer, when heat is collected and stored, firstly, the AC channel of the three-way valve 21 is opened, the BC channel is closed, the liquid absorption cores 13 positioned in the upper section and the lower section of the second fluid pipe 3 are connected into a whole, and then the vibration driving motor 15 is started, so that the lower cylinder 4-1 is driven by the rotation of the eccentric cam 16 to vibrate up and down. At the moment, the liquid phase-change working medium enters the heat exchanger 1 through the bent pipe 23 and the second fluid pipe 3 under the action of capillary force, absorbs heat energy from solar radiation and the environment to be subjected to phase-change evaporation to form a vapor phase-change working medium, then the vapor phase-change working medium enters the upper connecting sleeve 4-2 part of the inner cylinder 4 through the first fluid pipe 2 under the driving of phase-change force, is condensed into the liquid phase-change working medium under the cooling action, and finally quickly drops into the lower cylinder 4-1 through the sieve mesh partition plate 4-3 under the promoting action of vibration, so that the circulation process of the phase-change working medium 12 is completed. Meanwhile, the heat released to the wall surface of the inner cylinder 4 is gradually diffused to the peripheral energy storage body 25 under the transmission of the lubricating heat-conducting medium 5, and finally the heat collection and heat storage processes in summer are completed. In the process, the multifunctional weather station 17 calculates weather parameters such as a solar azimuth angle, an altitude angle, an ambient wind speed and temperature which are monitored in real time, and the intelligent controller 18 sends an optimal position instruction to the driving actuator 19 according to the weather parameters, and drives the heat exchanger 1 to rotate to a target position, so that the heat exchanger 1 works under the optimal heat collection efficiency. When heating in winter, the heat exchange fluid interface of the heat exchanger 1 is connected with a heating system. First, the BC channel of the three-way valve 21 is opened and the AC channel is closed, the wicks 13 located in the upper and lower sections of the second fluid pipe 3 are immediately disconnected from each other and cannot generate continuous capillary force, and then the vibration driving motor 15 is started, so that the lower cylinder 4-1 vibrates up and down by the rotation of the eccentric cam 16. At this time, under the promoting action of continuous heating and vibration of heat accumulated in the energy accumulator 25 in summer, the liquid phase change working medium at the bottom of the lower cylinder 4-1 quickly absorbs heat, changes phases and evaporates into a vapor phase change working medium, penetrates through the sieve hole partition plate 4-3 under the driving action of phase change force, enters the upper connecting sleeve 4-2, and enters the heat exchanger 1 through the first fluid pipe 2. Because the temperature at the heat exchange fluid inlet of the heat exchanger 1 is lower, the vapor phase change working medium is cooled and releases heat to the low-temperature fluid to be condensed into a liquid phase change working medium; under the action of gravity, the liquid phase-change working medium finally flows back to the lower cylinder 4-1 through the second fluid pipe 3, the bypass pipe 20 and the bent pipe 23 to complete the circulation process of the phase-change working medium 12; meanwhile, the heated heat exchange fluid working medium flows out from the heat exchange fluid outlet and is conveyed to the energy utilization side, and finally the heat supply process in winter is completed.

Winter cold collection and storage and summer cold supply modes: when cold collection and storage are carried out in winter, firstly, the BC channel of the three-way valve 21 is opened and the AC channel is closed, the liquid absorption cores 13 in the upper section and the lower section of the second fluid pipe 3 are immediately disconnected with each other and cannot generate continuous capillary force, and then the vibration driving motor 15 is started, so that the lower cylinder 4-1 is driven by the rotation of the eccentric cam 16 to vibrate up and down. At this time, because the ground temperature of the energy storage body 25 is obviously higher than the outdoor environment temperature, under the continuous heating action of the energy storage body 25 and the promotion of vibration enhancement of the vibration device, the liquid phase change working medium in the lower cylinder 4-1 continuously absorbs heat and changes phase to evaporate into a vapor phase change working medium, under the driving action of phase change force, penetrates through the sieve separator 4-3, enters the upper connecting sleeve 4-2, enters the heat exchanger 1 through the first fluid pipe 2, absorbs the cold energy from the environment to change phase and condense into the liquid phase change working medium, and enters the lower cylinder 4-1 through the second fluid pipe 3, the bypass pipe 20 and the elbow pipe 23 under the action of gravity, and finally the circulation process of the phase change working medium 12 is completed; meanwhile, the phase change working medium 12 continuously dissipates the heat in the energy storage body 25 to the environment, so that the environment cold energy is gradually diffused to the peripheral energy storage body 25, and finally the cold collection and storage processes in winter are completed; in the process, the multifunctional weather station 17 calculates weather parameters such as a solar azimuth angle, an altitude angle, an ambient wind speed and temperature which are monitored in real time, and the intelligent controller 18 sends an optimal position instruction to the driving actuator 19 according to the weather parameters, and drives the heat exchanger 1 to rotate to a target position, so that the heat exchanger 1 works under the optimal cooling efficiency. And when cooling is carried out in summer, the heat exchange fluid interface of the heat exchanger 1 is connected with a cooling system. Firstly, opening an AC channel of a three-way valve 21 and closing a BC channel, enabling the liquid absorption cores 13 in the upper section and the lower section of the second fluid pipe 3 to be communicated with each other, and then starting a vibration driving motor 15, so that the lower cylinder 4-1 vibrates up and down under the driving of the rotation of an eccentric cam 16; the liquid phase-change working medium enters the heat exchanger 1 through the bent pipe 23 and the second fluid pipe 3 under the action of capillary force; at the moment, because the temperature at the heat exchange fluid inlet is higher, the liquid phase-change working medium absorbs heat from the high-temperature fluid and is subjected to phase-change evaporation to become a vapor phase-change working medium; under the action of phase change force, the vapor phase change working medium finally enters the upper connecting sleeve 4-2 through the first fluid pipe 2, is condensed into liquid phase change working medium under the cooling action of the vapor phase change working medium, and finally quickly drops into the lower cylinder 4-1 through the sieve mesh partition 4-3 under the promotion action of vibration, so that the circulation process of the phase change working medium 12 is completed; meanwhile, the cooled heat exchange fluid working medium flows out from the heat exchange fluid outlet and is conveyed to the energy utilization side, and the summer cooling process is completed.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
