Modular solar heat collector

Abstract

The invention discloses a modular solar heat collector, relates to the technical field of solar photothermal application, and solves the technical problems of weak roof utilization rate and low heat collecting efficiency in an existing heat collector. The heat collector comprises at least one heat collecting component, wherein the heat collecting components comprise heat collector brackets, and heat collector modules fixed on the heat collector brackets; the heat collector brackets are square frame bodies; a plurality of front support feet are pivoted at the bottom ends of the front sides of the heat collector brackets, and a plurality of length-adjustable back support feet are arranged at the bottom ends of the back sides of the heat collector brackets; house connecting pieces are fixed at the lower ends of all the front support feet and all the back support feet; the heat collector modules comprise heat absorbing plates, and two water access pipes and multiple heat collecting pipes respectively mounted on the heat absorbing plates; three-way pipes are connected to the two ends of the two water access pipes; and the heat collector modules in the adjacent heat collecting components are interconnected through the three-way pipes at the ends of the water access pipes. The heat collector, provided by the invention, is specifically suitable for transforming a solar water heating system of an existing residential building.

Description

technical field [0001] The invention relates to solar photothermal application technology, in particular to a technology of modularized solar thermal collectors. Background technique [0002] The common solar collectors on the market are relatively large in size, and the hot water production capacity of a single block is mostly 80-120L. At present, building integration of solar water heating systems mostly occurs in new buildings. The installation of heat collectors is considered during the construction period of houses. Usually, embedded parts are embedded or heat collectors are embedded in roofing materials. [0003] With the continuous advancement of energy conservation and emission reduction, the demand for energy-saving renovation of existing residential buildings is increasing. The prominent problems in the solar water heating system renovation projects of existing residential buildings are: the roof area of ​​existing residential buildings is limited, and there are ma...

Problems solved by technology

[0003] With the continuous advancement of energy conservation and emission reduction, the demand for energy-saving renovation of existing residential buildings is increasing. The prominent problems in the solar water heating system renovation projects of existing residential buildings are: the roof area of ​​existing residential buildings is limited, and there are many tigers. Windows and other roof shapes, larger collectors cannot make good use of the roof space

If the installation type is inlaid, it will cause great damage to the existing roof waterproof layer and other structures, and the slope of the building roof is often different. If a unified collector bracket is used, the actual installation heat collection angle will be different from the design heat collection angle. Inconsistent, unable to achieve the best heat collection efficiency
