Description
Technical field
The utility model relates to a kind of water heater, especially a kind of non-water tank solar water heater.
Background technology
Solar water heater is the big industry of one in the solar energy application of result; It provides the New-type water heater product of environmental protection, energy-saving safe, health for the common people; Solar water heater is exactly the radiant heat energy that absorbs solar energy, and heating cold water offers the energy-saving equipment that people use in life, production.
The set of systems of solar water heater commonly used becomes at present:
One, heat collector:
Heat collecting element in the system.Its function is equivalent to the electrothermal tube in the electric heater.Different with electric heater, gas heater is, the solar thermal collector utilization be the radiations heat energy of the sun, so can only have the daytime that shines upon heat time heating time.
Two, attemperater:
The same with the attemperater of electric heater, be the container of stored hot water.Because solar water heater can only work by day, and people generally just use hot water at night, thus must through attemperater heat collector by day the hot water storage of output get up.Volume is the summation of every night with the hot water amount, generally adopts happy together enamel inner container pressure-bearing attemperater.
Three, connect pipeline:
Hot water is transported to attemperater, cold water is transported to the passage of heat collector from attemperater from heat collector, make whole system form the loop of a closure.Reasonable in design, connecting correct circulating line, whether to reach optimum Working to solar energy system most important.Hot water pipeline must be done insulation and handle.Pipeline must have very high quality, guarantees to have the service life more than 20 years.
The shortcoming of solar water heater commonly used is at present: 1, and in order to guarantee the urbanite water consumption amount, so water tank will have certain volume, otherwise reservoir storage is not enough.But volume is big inconvenience is installed, and takies more space.2, in high-rise residential quarter, urban district, have only the resident on upper strata that solar water heater can be installed, the resident of middle lower floor just can't install (because of its volume must be placed in roof greatly).3, the heat storage capacity of water is general, and the thermal efficiency is not high.4, water tank needs regularly to clean incrustation scale, and is cumbersome.
Summary of the invention
The purpose of the utility model is to provide a kind of easy for installation, and heat storage capacity is good, the non-water tank solar water heater that volume is little.
The utility model is achieved in that a kind of non-water tank solar water heater, comprises water inlet, delivery port, heat collector, is provided with metallic water pipe in the heat collector, it is characterized in that also being provided with in the heat collector heat-storing material and electric thermophore.
Said heat-storing material is a phase-change material, and phase-change material has the ability that in certain temperature range, changes its physical state.With the solid-liquid phase change is example, when being heated to fusion temperature, just produces the phase transformation from solid-state to liquid state, and in the process of fusing, the phase-change material absorption also stores a large amount of latent heat; When phase-change material cooled off, the heat of storage will be dispersed in the environment in certain temperature range and go, and carries out from liquid state to solid-state reverse transformation; In these two kinds of phase transition process, energy stored or that discharge is called latent heat of phase change, when physical state changes; The temperature of material self almost remains unchanged before phase transformation is accomplished; Form a wide temperature platform, though temperature-resistant, the latent heat that absorbs or discharge is quite big.Phase-change material is a kind of material of developing in recent years; Utilize certain this material under specified temp; Absorb or release heat through phase transformation, the design of its latent heat, fusing point and thermal conductivity factor meets the demand of solar water heater, as long as it is filled in the heat collector cavity and encircles metallic water pipe; Metallic water pipe is set to spiral-shaped, to contact with heat-storing material better more fully.One end of metallic water pipe is communicated with water inlet, and the other end is communicated with delivery port.Holding heat accumulation in a large number when utilizing phase-change material more sunny by day than the characteristic of big several times of the heat storage capacity of water can; See through heat transfer device in the time of need be with hot water and be discharged into the running water of coming in, emit the running water heating through hot water outlet again from cold water inlet holding the heat energy of storage in phase-change material.
Electric thermophore is a kind of electrically heated rod of auto-control temperature; Its effect is to guarantee that heat-storing material can remain in the phase transition temperature scope (to be generally 68 degree Celsius when the not enough the moon of long-time sunlight, rainy day; To guarantee to have the leaving water temperature of 50 degree Celsius, the higher position has been wasted again).When the sun was sufficient, phase-change material can both reach more than 68 degree, so electric thermophore can not worked.
The workflow of the utility model is: when sunlight shines on the heat collector; The thermal energy conduction of its generation is to heat-storing material, and phase-change material absorbs through physical change and stores a large amount of heat energy, and is transmitted in the metallic water pipe; Cold water is come in to become hot water through heating and is gone out constantly circulation.
The present invention can be installed in roof, simultaneously because volume is little, also can be directly installed on the directly use of window outer (can accept the one side of Exposure to Sunlight) of each household as outdoor machine of air-conditioner.
Special, if bigger, also can several above-mentioned heat collector combinations be merged with the hot water amount, with the metallic water pipe polyphone, can produce a large amount of hot water.
In sum, the utility model has improved heat storage capacity greatly, and has saved these huge parts of water tank owing to adopted phase-change material as heat-storing material; Simultaneously because the existence of electric thermophore, can the auto-control temperature, so can there be sufficient hot water supply fine rainy day no matter.So the utility model is a kind of easy for installation, heat storage capacity is good, and volume is little, non-water tank solar water heater simple in structure.
