Solar heat collector with welding-free fins

Abstract

The invention discloses a solar heat collector with welding-free fins. The solar heat collector comprises a heat collector frame, a heat collector back plate, a heat preservation layer, working medium pipelines and a light transmitting layer, wherein the heat collector back plate, the heat preservation layer, the working medium pipelines and the light transmitting layer are sequentially arranged in the heat collector frame from bottom to top. The solar heat collector further comprises a junction box installed outside the heat collector frame. The heat collector frame comprises a frame main body and a pressing strip connected with the frame main body in a clamped mode. The frame main body comprises a vertical frame, a first transverse frame, a second transverse frame and a third transverse frame. The light transmitting layer comprises a lower tempered glass layer and an upper ultra white tempered glass layer, and a plurality of batteries and a plurality of flow concentration belts are arranged between the tempered glass layer and the ultra white tempered glass layer. The batteries are connected in series and / or connected in parallel into a plurality of battery packs through the flow concentration belts. All the battery packs are connected in series or in parallel through the flow concentration belts and are further electrically connected with the junction box. The solar heat collector with the welding-free fins is simple in structure, reasonable in design, good in sealing performance and high in heat collecting efficiency.

Description

technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a solar heat collector provided with welding-free fins. Background technique [0002] In the heat utilization of solar energy, the key is to convert the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. Heat collectors are generally divided into flat plate heat collectors, concentrating heat collectors and flat reflectors. [0003] Judging from the current state of world economic development, construction, transportation and industry have always been the three major energy-consuming industries, especially the construction industry. In developed countries, building energy consumption has accounted for 25-40% of the total energy consumption. In building energy consumption, heating, cooling, air conditioning and domestic hot water can ...
