U-shaped heating water channel suitable for region with rich light-heat resources

Abstract

The invention provides a U-shaped heating water channel. The U-shaped heating water channel consists of a U-shaped concrete water channel, a silver light-reflecting film, a colourless light transmitting plate and a black heat-absorbing plastic film, wherein the long-distance U-shaped curved-surface light-reflecting film reflects and gathers light for heating dynamic water flow gradually; and the black plastic film is utilized for absorbing solar energy and reducing heat loss of heated water. Compared with a conventional solar water heater, the U-shaped heating water channel has advantages on agricultural irrigation water temperature, is simpler in principle and structure, adopts easily available materials, adopts cheap apparatuses, is low in maintenance cost, is high in efficiency, is accepted by vast farmers and people more easily, and is convenient for popularization.

Description

technical field [0001] The invention relates to the technical field of solar heating, in particular to a U-shaped heating channel suitable for areas rich in light and heat resources. Background technique [0002] Since the rural revitalization strategy was put forward, agricultural development has once again attracted the attention of all walks of life. Agricultural research has gradually expanded from alkali control and insecticide to the influence of soil water and heat on crop growth, so temperature-appropriate irrigation has become an important task in agricultural irrigation. However, the temperature of snow water and groundwater in northern regions such as Xinjiang is far lower than the suitable temperature for crop growth. Such a temperature is not suitable for crop growth. Faced with this situation, many researchers have proposed that solar water heaters be used to heat low-temperature cold water and Use heated warm water for irrigation, but using solar water heater...

However, the temperature of snow water and groundwater in northern regions such as Xinjiang is far lower than the suitable temperature for crop growth. Such a temperature is not suitable for crop growth. Faced with this situation, many researchers have proposed that solar water heaters be used to heat low-temperature cold water and Use heated warm water for irrigation, but using solar water heaters to heat irrigation water is uneconomical, difficult to control the appropriate water temperature, and even causes a waste of resources. It can only be used in small fields and cannot be promoted in large fields. At the same time, the light area is not enough. Large, the influence of factors such as low utilization of light and heat
