Embodiment

[0025] refer to Figure 1-4 , a cooling method for an automatic cooling system for photovoltaic panels, mainly comprising the following operating steps:

[0026] S1. Panel installation: fix the bracket 2 stably, ensure that the photovoltaic panel 1 is in a horizontal state in the initial state, check the state of the evaporating liquid inside the heat-absorbing tube 3, and ensure effective heat absorption and gasification;

[0027] S2. Heat absorption imbalance: When the light irradiates the photovoltaic panel 1 from one side, the evaporating liquid will absorb heat and vaporize, so as to cool down the photovoltaic panel 1, so as to avoid the high temperature of the photovoltaic panel 1 from affecting the life, while the light is biased to the side The evaporation efficiency of the evaporating liquid is significantly higher, which causes the balance block 8 on this side to move a greater distance by the air pressure, causing the two ends of the photovoltaic panel 1 to be unbal...

Abstract

The invention discloses a cooling method of an automatic cooling system of a photovoltaic cell panel, and the cooling method mainly comprises the following operation steps: installation of a panel, heat absorption imbalance, and backflow deashing. Operation equipment used in the implementation process of the cooling method of the automatic cooling system of the photovoltaic cell panel comprises a photovoltaic panel. Supports are rotationally connected to the two sides of the photovoltaic panel, a plurality of heat dissipation mechanisms are fixed to the bottom of the photovoltaic panel, and each heat dissipation mechanism comprises two balance mechanisms which are symmetrically arranged. The method has the advantages that by arranging the heat dissipation pipe, when the temperature of the photovoltaic panel is too high and evaporated liquor is excessively gasified, the evaporated liquor can be discharged into the heat dissipation pipe in time, so that heat is diffused into surrounding low-temperature air to recover the liquid state, the evaporated liquor flows back into the heat absorption pipe through the backflow hole, and therefore external heat exchange is completed; continuous heat absorption and heat dissipation are achieved, it is guaranteed that the photovoltaic panel can work at the effective temperature, and the overall service life is prolonged.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a cooling method for an automatic cooling system for photovoltaic panels. Background technique [0002] Photovoltaic panels are devices that directly or indirectly convert solar radiation energy into electrical energy through photoelectric or photochemical effects by absorbing sunlight. Compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly; [0003] The conversion efficiency of photovoltaic cells is closely related to their own operating temperature, the higher the temperature, the lower the efficiency. The research data shows that the photoelectric conversion efficiency of the crystalline silicon battery will decrease to a certain extent when the battery temperature rises. In addition, after the battery reaches the upper limit of its operating temperature, the battery t...
