Problems solved by technology

However, in this combination method, due to the poor heat conductor in the solar cell module, the combined heat transfer area between the heating body and the solar cell backplane is small, the heat transfer efficiency is low, and the cost is high.
The current liquid immersion cooling method, due to the problem of liquid flow control, the heat transfer effect of the battery is not very good, and the uneven temperature distribution has an impact on the battery efficiency

Abstract

This invention discloses a light-gathering solar light-electricity-heat on-line device, which is connected with a solar condenser by a connecting bar, the electricity-heat on-line of the solar cell includes a liquid container with heat-collection working fluid, hot tubes are set on the side walls of the container and includes phase-change heat working fluid, the cell is connected with the hot tubes in the container fixedly, an inlet is set at the bottom and an outlet at the top, and the bottom face is transmissive, the outsides of the top face and the side walls are set with heat preservation material, which dips solar cells in a heat-collection working fluid and hot tube can carry solar heat not changed to electricity away quickly and guarantee uniform temperature of the cell surface to increase the photo-electric conversion rate.

Description

technical field [0001] The invention relates to a cascaded utilization device of solar energy under the condition of concentrating light, in particular to a solar photoelectric thermal combination device in the form of concentrating. Background technique [0002] At present, the main obstacle to the large-scale popularization and application of solar cell power generation is the high cost. One of the effective ways to reduce the cost of solar cell power generation is to use concentrating solar cells. Usually if the concentrating ratio exceeds 10, the system can only use direct sunlight Hj, so a tracking system must be used. When the concentration rate is high, the increase of the operating temperature of the solar cell under high concentration and high current will lead to a decrease in efficiency. Therefore, effective heat dissipation equipment is required. If the economy of the system is considered, the active type of electric heating can be used. Heat dissipation. [0...
