Heat pipe type wall-mounted double-effect flat plate heat collector

Abstract

The invention discloses a heat pipe type wall-mounted double-effect flat plate heat collector which comprises a box. The front side of the box is provided with a glass cover plate. The box is internally provided with a heat absorption plate and a water collection and heating tank which is provided with a water inlet and a water outlet. The rear side of the box is provided with an air inlet and an air outlet. The box is internally provided with an air flow channel attached to the rear side face of the heat absorption plate and a plurality of heat pipes. The evaporation sections of the heat pipes are embedded into the air flow channel, and the condensation sections of the heat pipes are embedded into the water collection and heating tank. A heat preservation layer is formed in the box by filling a heat preservation material. The heat pipe type wall-mounted double-effect flat plate heat collector can achieve the double-effect functions of water collection and heating and air collection and heating, and the solar heat utilization rate is greatly increased; by using the heat pipes, the problem that the temperature is too low in winter, and water freezes to cause copper pipe burst can be solved, maintenance cost is greatly reduced, and the service life is prolonged; and the condensation sections of the heat pipes directly heat the water, and heat transmission efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of solar thermal application, in particular to a heat pipe type wall-mounted double-effect flat plate heat collector. Background technique [0002] With the increasingly severe energy and environmental issues, the use, research and development of renewable energy is urgent. Solar energy has attracted much attention due to its wide range, cleanliness and ease of use. my country’s solar energy resources are very rich, the annual solar radiation energy that can be received throughout the country is about 5*10 22 J. How to effectively and fully utilize my country's abundant solar energy resources, reduce the consumption of traditional fossil energy, alleviate environmental pollution, and promote sustainable development is an important topic and has far-reaching significance. [0003] At present, in the field of solar thermal application technology, in the existing related patents, the multifunctional flat panel heat c...
