Abstract

The invention relates to a wall-hanging-type heat collector adopting half-edge compound parabolic concentrating devices. The wall-hanging-type heat collector comprises a flat glass plate (2), an outer frame (3) and a plurality of half-edge compound parabolic concentrating devices (1), wherein the flat glass plate (2) with a south-facing surface is vertically arranged and connected with the outer frame (3), the half-edge compound parabolic concentrating devices (1) are vertically distributed in the east-west direction, arranged in a space enclosed by the flat glass plate (2) and the outer frame (3) and fixed on the outer frame (3), and each half-edge compound parabolic concentrating device (1) comprises a half-edge compound parabolic reflecting plate (1-2) and a glass vacuum heat-collecting tube (1-1) which is arranged at the lower end of the half-edge compound parabolic reflecting plate (1-2). The wall-hanging-type heat collector has attractive appearance, convenient mounting, low cost, high solar energy utilization rate and heat-collecting temperature.

Description

technical field [0001] The invention relates to a solar energy concentrating and heat collecting device, in particular to a non-tracking light concentrating and heat collecting device, which belongs to the technical field of solar energy concentrating and heat collecting. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. [0003] Compound parabolic concentrator (CPC for short) is a non-imaging concentrator designed according to the principle of edge optics. In theory, the incident light within the acceptance angle range will reach the receiver directly or after reflection. For a given acceptance angle range, it can achieve the maximum concentration ratio, so it is applied in solar thermal and photovoltaic systems. In non-tracking, tracking (secondary reflector) systems. The establishment and development of the CPC model began in th...
