Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Heat flux, also known as heat flux, refers to the amount of heat passing through a unit cross-sectional area of ​​an object per unit time. Heat flux is usually used as a physical quantity to measure solar energy.

[0032] see figure 1 A structural schematic diagram of an embodiment of a concentrating solar heat flux detection device of the present invention is shown.

[0033] In this embodiment, the heat flux detection device includes: a heat sink mat...

Abstract

The invention discloses a device for detecting the density of heat flow of focused solar energy. According to the device, a heat sink material part provided with a heat absorbing cavity and a light collecting hole absorbs solar energy, the heat absorbed by the heat sink material part within a period of time is calculated through the change of the temperature of the heat sink material part within the period of time, and further the unit area of the light collecting hole and the heat of the solar energy absorbed within unit time, namely, the density of heat flow of the solar energy, are further calculated.

Description

technical field [0001] The invention relates to the application field of solar energy, in particular to a heat flux detection device for concentrated solar energy. Background technique [0002] At present, under the double pressure of energy depletion and environmental pollution, people's social life has been severely challenged. People have to devote all their resources to find new renewable energy sources, such as wind energy, solar energy, and biomass energy, which have been successively developed on a large scale. Among them, solar energy is generally favored due to its characteristics of unlimited reserves, universal distribution, clean utilization and economical efficiency, and has received widespread attention from all countries in the world. It has become one of the new energy sources that replace conventional energy sources. [0003] At present, scientists from various countries have carried out in-depth research in various fields of solar thermal applications, suc...
