Embodiment Construction

[0032] The heater of the present invention mainly uses solar energy for heating, and the device is portable and movable, which can meet the individualized heating requirements of each household. The spheres made of temperature-changing phase-change materials are arranged in layers, and absorb or release heat through cascading layers, which greatly improves the heat exchange efficiency, improves the stability of the hot air outlet temperature, and increases energy utilization. In Northwest my country and the Qinghai-Tibet Plateau region, there is plenty of sunlight during the day, and the temperature is suitable, but it is cold at night, the temperature difference between day and night is large, and the heating demand is relatively high. The present invention combines the solar collector 33 with the phase change thermal storage heater to solve Solving the problems of insufficient utilization of solar energy in severe cold areas, periodicity and instability, shifting peaks to fill...

Abstract

The invention discloses a filled cascade phase change heat storage solar hot air heater, which adopts a solar hot air heat collector to collect solar energy as an energy supply device, and encapsulates phase change material balls made of three kinds of phase change materials into a spherical shell In the body, it is filled in the phase change box in steps, and natural layers are formed in the integrated structure. Using the gaps formed by the natural accumulation between the spheres, coupled with the cascaded structure, it is possible to achieve sufficient heat exchange between the phase change material and the air. , Improve energy utilization efficiency. The combination of air collectors and solar phase change heaters realizes personalized home heating, and has the advantages of simple operation, quick and light movement.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a solar hot air heater, in particular to a filling type cascade phase change thermal storage solar hot air heater. Background technique [0002] The western part of my country has a small population density, a vast territory, and abundant solar energy resources. However, local residents use solar energy for daily heating less, and solar energy resources are wasted. Compared with this, the products that use electricity, coal, and petroleum as energy sources that people often use in daily life pale in comparison. The traditional energy coal and petroleum are non-renewable and increasingly exhausted. Electricity is a high-grade secondary energy source. Household electricity products are plentiful, but safety is also insufficient. If things go on like this, peak and low peak periods of electricity consumption will form, causing power shortages in power plants. Generally speaking, f...
