Spiral flow hot water air heating water tank

Abstract

The invention provides a spiral flow hot water air heating water tank, and belongs to the technical field of solar energy. The spiral flow hot water air heating water tank can use waster hot water such as solar energy hot water and recycled shower water to heat air, obtain hot air flow with sufficiently high temperature and high speed and be widely used in occasions such as heating, ventilation, warming, drying and pushing. Heat exchange and flow of the hot water and the air are both in a fully natural passive mode. The water tank can be applied in a unit mode and a scale combined mode. The unit and combined water tank comprises a heating speed increasing section and an introduction and eduction section. The heating speed increasing section comprises an inner ring water tank, an outer ring water tank and an air interlayer which are all formed by enclosing cylinder wall faces which are arranged inside and outside according to a common center axis. Due to the fact that laminated hole staggered horizontal pore plates are arranged on the inner ring water tank and the outer ring water tank, a channel of the air interlayer is narrow and small, staggered hole transverse cylinder pore wall is arranged in the channel of the air interlayer, natural spiral flow of the hot water and the air is formed, and strong heat exchange and strong speed increasing which are attached to the wall and spirally convective are achieved. An inner ring wall and an outer ring wall of the air interlayer adopt metal materials with good heat-conducting property, and other enclosing wall surfaces can adopt materials which are cheap and easy to machine such as plastics.

Description

technical field [0001] The invention relates to an air heating device using solar hot water, belonging to the technical field of solar energy. Background technique [0002] In the occasions where a certain high temperature or high-speed flowing air is required, the air heating of the general technology uses forced flow to enhance heat exchange and flow, the system is complex, and the energy consumption, cost and pollution are high. With the solar system, the system is not too complicated, it can operate in an all-natural passive manner, without pollution, and the investment and operation are economical. If practical, it is the preferred system. [0003] Air-heating solar thermal technology includes air heat collection and hot water heat collection. Generally, air heat collection is used to directly provide hot air for heating, heating, drying, ventilation, and promotion. It is widely used. The air system can directly collect heat to heat the air, but compared with hot wate...
