High-condensation heat accumulating type solar water heater

Abstract

The invention provides a high-condensation heat accumulating type solar water heater which comprises a condenser, a heat collection component, a connecting line, a heat accumulator and a base; the base supports the condenser; the condenser comprises a reflective plate and two side plates; the reflective plate and the two side plate defines a condensation cavity provided with an opening; the condensation cavity faces the sun at a preset angle; the heat collection component is fixedly arranged in the condensation cavity, and comprises a plurality of transversely arranged heat collection pipes; a first reflective surface and a second reflective surface which can reflect sun rays are formed on the inner surface of the reflective plate; a curvature radius of the second reflective surface is greater than that of the first reflective surface; the sunny sides of the heat collection pipes receive direct light rays from the sun; the night sides of the heat collection pipes receive reflected light rays from the first reflective surface and the second reflective surface; the heat accumulator is arranged in the heat collection pipes or the heat accumulator and the heat collection pipes form a circulation loop; and heat energy generated by the heat collection pipes is stored in the heat accumulator.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and relates to a high concentration heat storage type solar water heater. Background technique [0002] Solar water heaters use solar radiation to collect heat and are widely used in daily life. Traditional solar water heaters consist of heat collecting tubes, heat preservation water tanks and connecting pipes. The insulated water tank is a container for storing hot water. The cold water in the insulated water tank is sent to the heat collecting pipe through the pipe, and the hot water generated in the heat collecting pipe is sent to the insulated water tank through the pipe. The insulated water tank and the connecting pipe form a closed loop. The water tank not only causes installation inconvenience, but also has poor water quality, so traditional solar water heaters are gradually being replaced by tankless water heaters. [0003] Existing solar water heaters use two methods of external co...

Problems solved by technology

[0004] The existing reflector can only play a relative reflection role, and cannot make the heat collecting tube receive light at 360°, and there is a dead angle of reflection, so the heat collecting area is small, the heat collecting speed is slow, the thermal efficiency is low, and it cannot well adapt to the angle of the sun. Variation, poor spotlight effect

[0005] In addition, the tankless solar water heater uses heat storage to store heat energy, which can store a large amount of heat, but when used at the user end, the hot water that is too high cannot be used directly, and more cold water needs to be mixed in to reduce the heat, which causes heat loss. waste of
