Abstract
The utility model relates to a phase change heat accumulation formula solar water heater, it includes compound phase change heat accumulation layer, hot and cold water business turn over water pipe, evacuated collector tube, parts such as stainless steel inner bag. The phase-change heat storage type solar water heater designed by utilizing the principle that when a substance is directly changed into a liquid state from a solid state, phase-change heat is absorbed, and when the reverse process is carried out, the phase-change heat storage type solar water heater is designed by compounding a layer of phase-change heat storage material on the surface of a water heater inner container to control the water temperature of the water heater within a set range, so that people can conveniently bath. The scale formation and corrosion of the water tank accelerated due to overhigh water temperature in summer are reduced, the service lives of the water heater and a pipeline system are prolonged, and the maintenance and replacement costs are reduced; the phase-change composite layer also has the functions of heat insulation and heat preservation.
Description
One, technical field:
The utility model relates to a kind of phase-change heat-storage solar energy water heater, is that a kind of conversion of solar energy is the device of heat energy, promptly a kind of solar water heater that supplies people's bathing to use.
Two, background technology:
The hot water temperature that the daily bathing of people is used gets final product about 45 ℃, and intensity of solar radiation is the strongest noon, and the water temperature of known solar water heater can reach more than 70 ℃, has strengthened the temperature difference with environment like this, and then heat waste increases.Summer or when sunny, we can say that known solar water heater is hot operation basically, so, to cause the fouling and the corrosion of water heater to strengthen, strengthen the thermal losses of water heater, the service life of shortening equipment and pipe-line system, and increase the maintenance and the expense of exchange device and management road system more, to the cold day in winter, or solar radiation when not enough, known solar water heater's water temperature and heat insulation effect are undesirable again.
Three, summary of the invention
The purpose of this utility model provides a kind of phase-change heat-storage solar energy water heater, utilize material by solid-state when directly changing liquid state into, to absorb the heat of transformation, when carrying out inverse process, the phase-change heat-storage solar energy water heater that then will discharge the principle design of the heat of transformation is to control the scope of the water temperature of water heater in setting at water heater liner surface recombination last layer phase change heat storage material, to be convenient for people to bathing, the water tank that reduces summer and bring because of water temperature is too high quickens fouling and corrosion, improve the service life of water heater and pipe-line system, reduce the cost of safeguarding and changing.
Fig. 1 is that utility model is formed structure chart, and it comprises composite phase-change heat-storage layer 1, hot and cold water water inlet pipe and water outlet pipe 2, vacuum heat collection pipe 3, electrical auxiliary heater 4, stainless steel inner container 5, blast pipe 6.Low temperature phase change recuperation layer 1 is that the phase change heat storage material after fusing is applied to the outer surface of stainless steel inner container and makes, hot and cold water water inlet pipe and water outlet pipe 2 is arranged on the stainless steel inner container side-lower and connects with it, vacuum heat collection pipe 3 is arranged on the below of stainless steel inner container and is communicated with it, electric heating device is arranged on the stainless steel inner container side-lower and is communicated with it, and blast pipe 6 is arranged on the top of stainless steel inner container and is communicated with it.
When the water temperature of water heater is higher than 50 ℃, be applied to stainless steel inner container outer surface phase change heat storage material and begin fusing, the heat energy that will be higher than 50 ℃ of water temperatures is accumulated, when the water temperature of water heater is lower than 50 ℃, phase change heat storage material begins crystallization again, the heat of accumulating is discharged, the water temperature of water heater is controlled at the scope of setting, to be convenient for people to bathing.
Compared with prior art have following advantage:
1, the utility model is that water temperature with water heater is controlled at suitable temperature range, avoided the water heater temperature too high, thereby reduced the temperature difference of water heater temperature and environment, not only can reduce the thermal losses of water-heater water tank, also reduced water heater to the heat waste of user, and then improved the thermal efficiency that gets of whole water-heater system with this section of penstock feed pipe.
2, the utility model can be avoided the disadvantage of the frequent hot operation of water heater, and the operation of water heater long term high temperature can be quickened fouling and corrosion, the service life of shortening heat hydrophone and pipe-line system, and increase the cost of safeguarding and changing.
3, the phase transformation composite bed on water heater liner surface, it also has the function of heat-insulation and heat-preservation simultaneously.
Four, description of drawings
Fig. 1 is that the utility model is formed structure chart, and 1 is the composite phase-change heat-storage layer among the figure, the 2nd, and hot and cold water water inlet pipe and water outlet pipe, the 3rd, vacuum heat collection pipe, the 4th, electrical auxiliary heater, the 5th, stainless steel inner container, the 6th, blast pipe.
Five, the specific embodiment
Press the described structure of Fig. 1, it comprises composite phase-change heat-storage layer 1, hot and cold water water inlet pipe and water outlet pipe 2, vacuum heat collection pipe 3, electrical auxiliary heater 4, stainless steel inner container 5, blast pipe 6.Low temperature phase change recuperation layer 1 is that the outer surface that the phase change heat storage material after fusing is applied to stainless steel inner container is formed, hot and cold water water inlet pipe and water outlet pipe 2 is arranged on the stainless steel inner container side-lower and connects with it, vacuum heat collection pipe 3 is arranged on the below of stainless steel inner container and is communicated with it, electric heating device is arranged on the stainless steel inner container side-lower and is communicated with it, and blast pipe 6 is arranged on the top of stainless steel inner container and is communicated with it.Low temperature composite phase change heat-accumulation material described in the utility model, be to be composited with a kind of matrix (support) material by a kind of material for storing heat of phase change in low temperature, under the temperature that is higher than the matrix material fusing point, phase change heat storage material and matrix material are melted, mix, then mixture is applied to solar water heater's inner water tank outer surface, thing cooling to be mixed, its temperature is controlled between the fusing point of the fusing point of base material and phase change heat storage material, at this moment, matrix material begins to solidify, and phase change heat storage material still is liquid and remains in the matrix material of tridimensional network.Treat to cool off fully, promptly make the phase-change heat-storage composite inner liner.
