Transmission-type solar light condensing heat collection system

Abstract

The invention discloses a transmission-type solar light condensing heat collection system which comprises a condensing lens, a heat absorption part and a moving part. Light passing through the condensing lens is focused to form a focus area; and the moving part is connected with the heat absorption part and used for driving the heat absorption part to move to the focus area. According to the transmission-type solar light condensing heat collection system, the position of the heat absorption part is changed through the moving part so that the heat absorption part can be always in the focus area, and then light can be always gathered to the heat absorption part even if the focus area deviates due to the change of the solar altitude and the solar azimuth. As the size of the heat absorption part is far smaller than that of the condensing lens, compared with one-dimensional or two-dimensional rotation of a traditional condensing lens, moving parts in the whole transmission-type solar lightcondensing heat collection system can be greatly reduced, and the overall structure of the transmission-type solar light condensing heat collection system is simplified. As the light is directly gathered to the heat absorption part, light spots have a higher energy flow density and a higher condensation ratio, the condensation effect is good, and the utilization rate of solar energy is high.

Description

technical field [0001] The invention belongs to the field of solar energy concentration, in particular to a transmission type solar energy concentration and heat collection system. Background technique [0002] Solar energy is a clean and widely available renewable energy, and the utilization of solar energy has been extensively studied around the world. However, due to the low energy flux density of solar energy reaching the earth's surface, it is generally less than 1000W / m 2 , not suitable for high temperature heat utilization. Therefore, in order to increase the radiant energy flow density of solar energy, technicians have designed solar concentrators to gather and collect sunlight. [0003] The solar concentrator is generally a large glass reflector, and the sunlight can be transmitted through the solar concentrator for focusing. The technician installs a heat absorbing device at the focus to collect the heat of the sunlight. However, the incident angle of sunlight w...
