Novel efficient solar photovoltaic/ photo-thermal heat collection/ evaporator

Abstract

The invention relates to a novel efficient solar photovoltaic / photo-thermal heat collection / evaporator. The novel efficient solar photovoltaic / photo-thermal heat collection / evaporator comprises aphotovoltaic cell glass coating film, a photovoltaic cell, an EVA adhesive film, an electric insulation layer, a blowing-up plate and a heat preservation material. The novel efficient solar photovoltaic / photo-thermal heat collection / evaporator has the beneficial effects that the assembly adopts a novel blowing-up plate runner structure design, namely, the blowing-up plate with the runner designoptimized is adopted, compared with a PV / T assembly with air or water as a heat collection medium and a blowing-up plate which is not subjected to runner design optimization, the heat collection efficiency is high, and more efficient heat collection and photovoltaic cell cooling are achieved; and in addition, a blowing-up plate runner formed by combining a hexagonal runner and a grid type runner can achieve more uniform temperature distribution, and therefore the stability of photovoltaic cell current output is improved, and the service life is prolonged. The assembly is compact in structure,efficient, light and attractive, the occupied area of the assembly is reduced, the power generation and heat pump efficiency is improved, and the assembly has important significance in the field of renewable energy utilization and green buildings.

Description

technical field [0001] The invention relates to photovoltaic / photothermal coupling technology, which realizes efficient thermoelectric conversion of components through the optimized design of the flow channel, and particularly relates to a new type of high-efficiency solar photovoltaic / photothermal heat collector / evaporator. Background technique [0002] Nowadays, the world's energy consumption is increasing year by year, and China, as a country with the largest energy consumption and the largest carbon emission, is under increasing pressure for energy transformation and energy conservation and emission reduction. With the emergence of energy crisis and environmental crisis, the development and utilization of new energy is imminent. Solar energy has become the first choice among renewable energy due to its permanence, universality and environmental friendliness. There are two main ways to use solar energy: photovoltaic utilization and photothermal utilization. In the field o...

Problems solved by technology

Nowadays, common PV / T modules on the market are mainly promoted with water and air as the heat-collecting medium. Because they use the sensible heat of water and air for energy storage, the heat storage efficiency is far lower than that of refrigerants that use latent heat for energy storage. , so water-based or air-based PV / T modules require a larger installation area
