Abstract
The invention provides an anti-freezing type water-tank-free efficient flat plate solar water heater. A phase-change material is used as a heat storage medium for the solar water heater, and the problems that an existing phase-change heat storage solar water heater is high in cost and low in heat conducting efficiency are solved. The anti-freezing type water-tank-free efficient flat plate solar water heater comprises full-glass evacuated solar collector tubes, a header and a support. The header is provided with a water inlet and a water outlet and is further provided with a phase-change material injection port. The full-glass evacuated solar collector tubes contain the phase-change material. Finned tube exchangers are arranged in the full-glass evacuated solar collector tubes. Each whole evacuated solar collector tube is almost filled with the corresponding finned tube exchangers, and the finned tube exchangers make tight contact with the inner walls of the evacuated solar collector tubes. A small amount of space for expansion of the phase-change material is reserved in the upper portion of each evacuated solar collector tube. By the adoption of the anti-freezing type water-tank-free efficient flat plate solar water heater, due to the fact that the phase-change material is used as the heat storage medium, the characteristic that the heat storage capacity of the phase-change material is multiple times that of water or even higher, and consequently more heat can be stored is utilized. Due to the fact that a heat storage tank is removed, and the phase-change material is directly arranged in the evacuated solar collector tubes, cost is greatly reduced. The full-glass evacuated solar collector tubes directly transmit converted heat energy to the heat storage medium, and the heat efficiency is high. The evacuated solar collector tubes do not bear pressure, and hot water still flows out in a pressure-bearing manner.
Description
Technical field
The present invention relates to a kind of anti-freezing type cistern free high-efficient flat-plate solar water heater, belong to solar water heater field.
Background technology
Existing panel solar hot water, by flat plate collector, heat storage water tank, support, connects pipeline, controls the compositions such as parts.Wherein heat storage water tank is relatively costly, account for most of totle drilling cost.Additionally there are following shortcoming: one is that complexity installed by water tank, and volume takes up space more greatly.Two be flat plate collector be connected with water tank, water tank more with user's use water connecting line, pipeline heat waste is more.Three is system maintenance trouble.Four is that various parts installation is in disorder unsightly.
