Problems solved by technology

However, due to the complex manufacturing process of concentrated photovoltaics, high requirements for integrated systems, and high technical difficulties, there are not too many domestic enterprises involved in this field, and the production scale is still small.
[0005] The invention application with the application number CN201610143200 discloses a trough-type solar heat and power cogeneration receiver device. The defect of this design is that although power generation and heat collection are realized at the same time, the collected heat comes from the concentrated light collected by the condenser tube. The waste heat of the solar panels produces low-quality heat; and in this design, the position of the concentrating solar panels is fixed, and the ratio of the generated electricity to the collected heat is constant, and real-time regulation of electricity and heat cannot be realized. and flexible allocation

Abstract

The invention discloses a slot type solar combined heat and power generation device. The slot type solar combined heat and power generation device comprises a condensation heat collection module, a condensation photovoltaic power generation module and a function switching mechanism. The solar heat collection technology and the condensation photovoltaic power generation technology are combined well, and high-quality electric energy and heat energy can be produced; and meanwhile, the problem about the energy distribution ratio of solar energy of a certain area between condensation heat collection and condensation power generation and the problem about heat radiation of circuit boards of high condensation multiples are solved, and the utilization efficiency of solar energy of unit area can beimproved. According to the slot type solar combined heat and power generation device, operation of singly utilizing solar energy for power generation or heating is avoided, condensation heat collection and condensation power generation are integrated, and the device can flexibly adjust and control the thermoelectric ratio so as to meet the requirements of different application occasions for different ratios of heat energy and electric energy.

Description

technical field [0001] The invention belongs to the technical field of solar energy photothermal utilization in the field of new energy, and is a device capable of concentrating light and collecting heat and generating electricity simultaneously, and the ratio of collecting heat and generating electricity can be automatically adjusted in real time. Background technique [0002] In the field of solar concentrating light and heat utilization, the most commercialized is the trough concentrating heat collecting device. The trough type heat collector is to reflect and gather sunlight on the vacuum heat collector tube through the trough parabolic mirror, heat the medium, and send the generated steam to the steam turbine steering gear of the main powerhouse to realize solar thermal power generation. The outer part of the vacuum heat collector tube used in the trough thermal power station is a cylindrical glass tube shell, and the inner heat collector core tube runs through the vacu...
