Problems solved by technology

[0009] Since the heat collecting plate 13 in the above-mentioned prior art is mostly a flat plate, the light-receiving area is limited, and the light-to-heat conversion efficiency is low; , and then it can be transferred to the cold water to be heated, so the thermal resistance in this process is large, and the heat transfer efficiency of the system is also low

Abstract

The invention discloses a solar heat-collecting core which comprises a heat collecting plate and a bottom plate overlapped below the heat collecting plate. A water flowing channels is arranged between the heat collecting plate and the bottom plate; the peripheries of the heat collecting plate and the bottom plate are sealed; and the water flowing channel is formed between the heat collecting plate and the bottom plate to make cold water in the water flowing channel be directly heated by the heat collecting plate. Additionally, the heat collecting plate also comprises a plurality of protruding parts. The invention also provides a solar water heater and a heat collector of the solar water heater. The water flowing channel of the solar heat-collecting core is directly formed by the heat collecting plate and the bottom plate, cold water to be heated in the water flowing channel can be directly heated by the heat collecting plate, thus the heat transfer efficiency is remarkably improved. After the protruding parts are arranged on the heat collecting plate, the light area of the heat collecting plate is enlarged, so that the photo-thermal converting efficiency is improved; on the other hand, the arrangement of the protruding parts can enlarge the heat-exchanging area between the heat collecting plate and cold water, thereby the heat conducting efficiency can be further improved.

Description

technical field [0001] The invention relates to a heat collecting core for absorbing and transmitting solar energy. The present invention also relates to a heat collector comprising the above-mentioned heat-collecting core, and a solar water heater comprising the above-mentioned heat collector. Background technique [0002] Along with the raising of people's living standard, the application of water heater in daily life is more and more extensive. [0003] Existing water heaters are divided into gas, coal-fired, oil-fired water heaters, and several major categories such as electric water heaters according to energy sources. What the above-mentioned gas, coal-fired, and oil-fired water heaters consume are all non-renewable energy sources, and also cause environmental pollution; meanwhile, as energy prices continue to rise, the above-mentioned gas, coal-fired, and oil-fired water heaters are expensive to use, bringing users greater economic pressure. Because the electricity...
