Description
The utility model relates to a kind of vacuum heat collection pipe that is used for sun firing equipment.
The critical component of sun firing equipment is a vacuum heat collection pipe, and it has full glass type, heat pipe-type etc. a variety of.The main effect of vacuum heat collection pipe is to receive solar radiation and heat heat-carrying working medium.Heat-carrying working medium kind is a lot, and wherein modal is water, below mainly is that example describes with water, but is suitable for too for the heat-carrying working medium of other similar performance.All there is a shell outside of various vacuum heat collection pipes, the air pressure in the space that is closed by this shell is vacuum state, its effect is to allow solar radiation enter vacuum heat collection pipe, can form the insulating that stops outside convection current of vacuum heat collection pipe internal heat and conduction again.Hot pipe type vacuum heat collection pipe has the shell of an individual layer, and be equipped with as the heat pipe of heat-exchanger rig and fin thereof its inside, and the surface of heat pipe and fin thereof is heat-absorbent surface and is coated with the solar radiative absorption coating.The effect of this heat-exchanger rig is exactly the heat transferred water of being responsible for receiving.After heat pipe and fin thereof received the heat of solar radiation, heat pipe was derived vacuum heat collection pipe with heat immediately, passed to the water that stores in the solar hot-water equipment simultaneously.Water constantly absorbs and stores the heat that heat pipe is derived, and makes vacuum heat collection pipe keep thermal equilibrium state, and that guarantees that it can be safe and reliable carries out heat reception work.These water are stored in the outer tank and coupled pipeline of solar hot-water equipment.The shell of full glass type vacuum heat collection pipe is a double-layer glass structure, the middle interlayer state that is closed and is evacuated.The interior Guan Like holding portion water of shell, the outer surface of interior pipe is heat-absorbent surface and applies the solar radiative absorption coating, water is directly heated by solar radiation in the pipe in this, this part water ceaselessly carries out heat convection with the outer tank and the ducted cold water that links to each other in the heated while, so just can make vacuum heat collection pipe remain thermal equilibrium state, it is overheated to prevent.But water breakthrough not only has the effect that absorbs heat in full glass type vacuum heat collection pipe also is responsible for exchange heat simultaneously, has the effect of similar heat-exchanger rig.The operation principle of existing other kind vacuum heat collection pipe and structure are substantially all similar with above-mentioned two kinds of vacuum heat collection pipes.By existing vacuum heat-collecting tubular construction and operation principle as can be known: the necessary condition that existing vacuum heat collection pipe can operate as normal is must store abundant water in the solar hot-water equipment at its place all the time and cooperate its work.This characteristic of existing vacuum heat collection pipe has brought serious potential safety hazard for solar hot-water equipment: first if pipe leakage or cause unexpected dehydration by operate miss, to cause not having sufficient water and vacuum heat collection pipe cooperating in the solar hot-water equipment, make thermal balance destroyed, this moment dry combustion method takes place very easily or make remaining water boiling vaporization.The solar radiation meeting is heated to very high temperature to the parts in the vacuum heat collection pipe when dry combustion method takes place.Existing vacuum heat collection pipe very easily causes performance degradation, the lost of life even scraps after being surpassed certain hour by dry combustion method, also may burn out other parts of solar hot-water equipment.Because the probability that pipe leakage or operate miss take place is very high, particularly in the domestic consumer, so these characteristics of existing vacuum heat collection pipe will constitute potential threat to service life, safety in operation and the reliability of solar hot-water equipment.The second, when bad weather, threaten bigger to safe operation for cooperating existing vacuum heat collection pipe work long-time water that stores in solar hot-water equipment.This is because solar hot-water equipment need work long hours through being everlasting to wait in the bad weather in freezing winter and in sultry summer, at this moment the also inevitable atrocious weather that experience simultaneously of water that is used to cooperate vacuum heat collection pipe work of its internal reservoir.If the time that bad weather continues is longer, the danger frozen or boiling of the water in the solar hot-water equipment is just very big, and it is badly damaged that solar hot-water equipment is subjected to.The accident of bursting by freezing pipeline for example often takes place the winter of severe cold, reason be exactly since for a long time not enough the and severe cold of solar radiation make due to the water of long-time delay in the solar hot-water equipment freezes in the part, even the solar hot-water device external uses preferably insulation material can not avoid this type of problem fully.At present, ensure solar hot-water equipment trouble free service in bad weather, can only on solar hot-water equipment, install the servicing unit of the round-the-clock safe operation of various guarantees additional, as ribbon heater etc., complexity, reliability decrease, equipment initial investment and operating cost all are difficult to bear but can cause whole solar hot-water equipment to become very like this.
The purpose of this utility model provides a kind of all-weather vacuum heat collecting pipe, during this all-weather vacuum heat collecting pipe work, do not need to store water in the solar hot-water equipment at its place and cooperate its work, thereby make the work of solar hot-water equipment more safe and reliable, and it can make solar hot-water simplified equipment structure reduce cost.
Technology contents of the present utility model is such: this all-weather vacuum heat collecting pipe comprises shell, the air pressure in the space of being sealed by this shell is vacuum state, heat-exchanger rig is arranged in the shell, apply the solar radiative absorption coating on the heat-absorbent surface, it is characterized in that: special-purpose heat storage is equipped with in the shell the inside, this special use heat storage portion at least within it has accumulation of heat working medium, and heat-exchanger rig and special-purpose heat storage are complementary.
Effect of the present utility model is such, the first, need in solar hot-water equipment, not store water during the work of this all-weather vacuum heat collecting pipe and keep the thermal balance of self, eliminate because of the solar hot-water equipment dry combustion method due to the unexpected dehydration or the remaining water hidden danger such as vaporization of seething with excitement.This is because special-purpose heat storage is housed in the shell of all-weather vacuum heat collecting pipe, the heat of solar radiation is absorbed by the solar radiative absorption coating later through shell, vacuum layer etc., the heat that the solar radiative absorption coating absorbs is heated special-purpose heat storage, heated special-purpose heat storage can utilize the accumulation of heat working medium of himself to absorb continuously and store these heats, can burn out other parts thereby these heats can only not accumulated in this special use heat storage gradually.As seen this all-weather vacuum heat collecting pipe is a thermal balance of keeping self with the accumulation of heat working medium of self, so can not take place because of the dry combustion method due to the unexpected dehydration again or make remaining accidents such as water boiling vaporization.And existing vacuum heat collection pipe is that the heat-carrying working-medium water is used as accumulation of heat working medium simultaneously, in case be used to after the unexpected dehydration absorb a large amount of minimizings of accumulation of heat working medium meeting of heat or disappear, so must cause thermal balance destroyed, safety is constituted a threat to.Need in solar hot-water equipment, not store water simultaneously when the second, this all-weather vacuum heat collecting pipe is worked and serve as accumulation of heat working medium, water only flows through solar hot-water equipment rapidly when needed as heat-carrying working medium to be taken away heat and gets final product, so the time that water exists in solar hot-water equipment is very short, can be safer when running into bad weather.This is because the vacuum of being pumped into after the shell sealing makes the special-purpose heat storage, heat-exchanger rig of shell the inside etc. all be in fabulous heat-insulation and heat-preservation state, after so all-weather vacuum heat collecting pipe receives solar radiation, can be directly carry out heat by the accumulation of heat working medium of special-purpose heat storage self and accumulate and store, prior art then need utilize the water that stores to finish this process in having the outer tank of insulation effect.Because all-weather vacuum heat collecting pipe self has the heat-exchanger rig that mates with special-purpose heat storage, can need heat and export hot water immediately again by the user.That is to say that all-weather vacuum heat collecting pipe has stored a lot of heats through after abundant sunshine, as long as the user needs, immediately just can be by heat-exchanger rig heating and output hot water; If temporarily need not export hot water, it is standby to allow heat be stored in the special-purpose heat storage.As seen this all-weather vacuum heat collecting pipe is that stored hot water is become direct store heat with the difference of prior art, and the reception of heat, accumulate, process such as storage can both independently be finished by all-weather vacuum heat collecting pipe, need in solar hot-water equipment, not store water and serve as accumulation of heat working medium.So use the solar hot-water equipment of this all-weather vacuum heat collecting pipe can not establish outer tank and relevant device, make that structure is simplified, reliability improves, cost descends; The more important thing is that it can make solar hot-water equipment all be in inner anhydrous state in the overwhelming majority working time, meets with the safe operation that bad weather influences solar hot-water equipment because of water during this period never again.Have only the of short duration moment that need export hot water as the user, extraneous water is heated after just can entering the heat-exchanger rig of the solar hot-water equipment and the all-weather vacuum heat collecting pipe of flowing through, and flows out solar hot-water equipment then rapidly and directly supplies the user, and water is detained hardly therein.As seen Wai Jie water flows through the time of the solar hot-water equipment that uses this all-weather vacuum heat collecting pipe, the time that stores water when working than the solar hot-water equipment that uses existing vacuum heat-collecting pipe manufacturer is short a lot, so when other condition is identical, this all-weather vacuum heat collecting pipe can make solar hot-water equipment influenced by bad weather to cause the possibility minimum of fault, and security is better.
