Description

A kind of solar water heater circulation attemperater

The utility model relates to solar utilizing equipment, the circulation attemperater that can be incubated for a long time that is specifically related to use on a kind of solar water heater.

Solar energy is one of the cleanest energy of generally acknowledging in the world, people in the long-term production of using conventional energy resource (as coal, oil etc.), practical experience of life, when enjoying their " grace " for the human light and heat that brings, also tasted varieties of the disaster that these non-clear energy sources cause to the mankind, the most outstanding is exactly the environmental pollution that is caused in the process of using these energy or its product.Atmosphere pollution is the most outstanding example, and the formation of " mist is all " has one by one beaten alarm bell for human using energy source structure---must the new more clean energy of development and use.Solar energy is exactly one of human use's energy the earliest, but owing to technical reason, no matter human utilization to solar energy from quantity or on quality (efficient), all reaches the desired and real available level of people far away.The efficient of solar energy when being converted into the energy form that can directly utilize is lower, and high-level utilization also is difficult to industrialization, and the easiest utilizes mode with regard to solar water heater.Existing solar water heater structure all is made up of a solar heat-collection plate and a water storage box basically.The insulating power of the water storage box of the solar water heater of this structure is poor, generally only can be incubated one day or the shorter time, therefore it only to be suitable for the sunshine-duration long, use in the area of the few and lasting weak point of rainy weather, and just be difficult to bring into play its cleaning, effect easily for the more area of those cloudy weather for several days running weather.The popularization that has also influenced solar water heater thus greatly is with universal.The design people has developed a kind of solar water heater that can be incubated for a long time circulation attemperater through long-term putting into practice, study, and its heat insulation effect of evidence is good.

It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, the solar water heater that can be incubated for a long time circulation attemperater.

The utility model is achieved in that it is provided with cyclic water tank and main boiler, reach the outside between the two and be covered with heat-insulation layer, cyclic water tank is provided with the water inlet pipe and water outlet pipe that is connected with the hot-water line and the cold water pipe of solar heat-collection plate respectively, the circulation pipe of hot water between cyclic water tank and main boiler enters main boiler, draws through the hot water outlet on main boiler top again.

Because the utility model adopts two groups of water tank thermal cycles and insulation construction design, hot and cold water is difficult for mixing, and has reduced thermal loss, strengthens the temperature difference of the cold and hot end of solar heat-collection plate, has improved the utilization ratio of solar energy, can satisfy the requirement of the long-time insulation of hot water.

Below in conjunction with accompanying drawing and embodiment the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.
