Double-air-channel solar hot air heater

Abstract

The invention discloses a double-air-channel solar hot air heater. The double-air-channel solar hot air heater comprises a heat insulation box, a first draught fan, a second draught fan, heat accumulation plates, an air mixing tank and an air port shell. The heat insulation box is internally provided with a cavity. A first air inlet channel is arranged at one end of the cavity. A hot air channel is arranged at the other end of the cavity. The first draught fan is mounted at the inlet end of the first air inlet channel. One end of the hot air channel communicates with the cavity. The other endof the hot air channel communicates with the air mixing tank. The bottom of the air mixing tank communicates with a second air inlet channel. The second draught fan is arranged at an inlet of the second air inlet channel. The upper end of the air mixing tank is connected with the air port shell. The heat accumulation plates are arranged in the cavity of the heat insulation box. The double-air-channel solar hot air heater conducts heat supply through the double air channels, namely, the hot air channel and a normal-temperature channel. Cold air and hot air flowing out form the double air channels are mixed in the air mixing tank, so that the air is mixed fully, and the stability of hot air of an air outlet is achieved.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a double-channel solar hot air heater. Background technique [0002] At present, my country's energy structure consumes a lot of conventional energy, causing serious pollution, especially in the design and use of buildings, the total energy consumption of buildings accounts for more than 1 / 3 of my country's total energy consumption. The development and utilization of solar energy in the process of building design and operation can adjust the structure of building energy consumption and realize clean heating. In recent years, the popularization and use of solar passive utilization technologies that benefit directly from windows, thermal storage walls, additional sunlight rooms and their combinations have greatly promoted the development of passive buildings and solved a series of building heating problems. A series of new problems such as the large te...
