Abstract

The utility model relates to the technical field of solar heating, in particular to a heat collector water storage tank. The heat collector water storage tank comprises a phase-change material layer which is arranged between an inner container and a heat preservation layer. When the water storage tank is in the process of heat storage, the phase-change material layer arranged on the inner container is in the process of heat absorption, and due to the fact that a cold water inlet pipe is arranged on a lower end cover, in the actual process of water flowing out, water temperature in the whole inner container is distributed step by step in an top-hot and bottom-cold mode. When hot water needs to be used, a water outlet pipe on an upper end cover is opened, hot water on the upper layer reaching set usage temperature can flow out from the water outlet pipe, water on the lower layer rushes to the upper layer, temperature is reduced step by step, when the water temperature can not reach the set usage temperature, the water can not flow out from the water outlet pipe, and then the phase-change material layer begins to sent heat so that the temperature of the water on the lower layer rises to achieve the set usage temperature, according to the heat collector water storage tank, actual available hot water amount is increased, and a utilization rate is improved.

Description

The heat collector storage tank
Technical field:
The utility model relates to a kind of solar energy heating technical field, relates in particular to a kind of heat collector storage tank.
Background technology:
Along with the raising of living standards of the people, water heater application in daily life is more and more extensive.
Existing water heater is divided into combustion gas according to energy source, coal-fired, several large classes such as fuel-oil water heater and electric heater, above-mentioned combustion gas, coal-fired, fuel-oil water heater consumption all are non-renewable energy resources, can cause the pollution of environment, simultaneously, continue surging today in energy prices, above-mentioned combustion gas, coal-fired, the cost of use of fuel-oil water heater is high, bring larger financial burden to the user, because power consumption is large, electricity price also has the trend of sustainable growth, also there is no small obstacle in the extensive use of above-mentioned electric heater, under this background, solar water heater is with its energy clean environment firendly, cost of use is lower, the advantage such as easy to use is widely used, this brings significant impact to Chinese national economy and environmental protection cause, simultaneously, because solar water heater uses limitation when not having sunlight, the two-in-one water heater of a kind of solar energy-electric energy has just appearred, and it is well-known, the part of most critical is storage tank in the water heater, a kind of storage tank of the prior art, it comprises shell, inner bag, be arranged at the heat-insulation layer between shell and inner bag, upper end cover, bottom end cover, the magnesium rod, heating tube, water inlet pipe and outlet pipe, described upper end cover and bottom end cover are installed on respectively up and down two ends of shell, one end of described magnesium rod and heating tube is installed on bottom end cover, the other end is free end and is built in inner bag, described water inlet pipe is installed on bottom end cover, described delivery port is installed on upper end cover, adopt the heat collector of above structure, scientific structure design is reasonable, the heating water effect is remarkable, but still there is following shortcoming: because cold water inlet is arranged at bottom end cover, therefore under actual conditions, water temperature in the whole inner bag is upper heat and lower cold and distributes step by step, in the situation of setting serviceability temperature, actual available hot water only accounts for the part of whole storage tank capacity, the remaining energy of failing to reach in the water of setting serviceability temperature also can only be wasted, utilization rate is not high, limited the service efficiency of this kind of heat collector, be unfavorable for promoting.
The utility model content:
The technical problems to be solved in the utility model is, provides a kind of capacity usage ratio higher, can utilize the more heat collector storage tank of hot water amount.
For solving the problems of the technologies described above, the utility model has adopted a kind of like this heat collector storage tank: it comprises shell, inner bag, be arranged at the heat-insulation layer between shell and inner bag, upper end cover, bottom end cover, the magnesium rod, heating tube, water inlet pipe and outlet pipe, described upper end cover and bottom end cover are installed on respectively up and down two ends of shell, one end of described magnesium rod and heating tube is installed on bottom end cover, the other end is free end and is built in inner bag, described water inlet pipe is installed on bottom end cover, described delivery port is installed on upper end cover, it also comprises phase-change material layers, and described phase-change material layers is arranged between inner bag and the heat-insulation layer.
Described phase-change material layer height is the 1/2-1/3 of inner bag height.
Described phase-change material layer height is 1/3 of inner bag height.
Described phase-change material layers is the phase-change material layers that is comprised of solid phase change material.
After adopting above structure, the utility model compared with prior art, have the following advantages: when in the process of storage tank in accumulation of heat, the phase-change material layers that is arranged on the inner bag also is in the endothermic process, again because cold water inlet is arranged at bottom end cover, in actual exiting water process, water temperature in the whole inner bag is upper heat and lower cold and distributes step by step, when needs use hot water, open the outlet pipe that is arranged at upper end cover, be in the hot water upper strata and that reach the setting serviceability temperature, just emitted from outlet pipe, the water of lower floor is just poured into the upper strata, temperature descends step by step, in case water temperature can not reach the setting serviceability temperature, water just can not be released outlet pipe, this moment, phase-change material layers just began heat release, so that the temperature of lower layer of water rises a bit to reach the setting serviceability temperature again, increased the actual available heat water yield, improved utilization rate, also improved the service efficiency of this kind of heat collector, be conducive to promote.
As preferably, described phase-change material layer height is the 1/2-1/3 of inner bag height, having under the identical effect, and economical with materials, and utilization rate is higher.
As another preferred, described phase-change material layer height is 1/3 of inner bag height, having under the identical effect, and economical with materials, and utilization rate is the highest.
