Description

Technical Field

[0001] The utility model relates to the technical field of heat collectors, in particular to a concentrating solar PVT heat collector. Background Art

[0002] ‌PVT collector‌, full name Photovoltaic Thermal Collector, is a technology that combines photovoltaic power generation and photothermal utilization. The PVT collector generates electricity through the photovoltaic effect, and at the same time uses the thermal effect of sunlight to heat the heat transfer medium, thereby improving the heat collection efficiency‌. The concentrating PVT collector mainly uses high-efficiency solar cells (such as gallium arsenide solar cells), and realizes efficient energy conversion through the concentrating part, the solar cell part and the backplane cooling part. The collector can be divided into liquid collector and air collector according to the type of heat transfer medium: the liquid collector uses liquid as the heat transfer medium, while the air collector uses air as the heat transfer medium. Depending on the applicable scenario, people can choose a liquid collector or an air collector. However, with the continuous diversification of people's needs, a single collector can no longer meet people's needs. Based on this, the utility model proposes a concentrating solar PVT collector.‌‌ Utility Model Content

[0006] Furthermore, the light-concentrating component is composed of a plurality of photovoltaic panels, and the shape of the plurality of photovoltaic panels is a trough parabolic shape.

[0007] Furthermore, the second supporting component includes a plurality of supporting assemblies, one end of each supporting assembly is circumferentially distributed around the outer periphery of the focusing component, and the other end thereof converges at a point.

[0010] Furthermore, air holes are symmetrically arranged on the heat exchange component, and the air holes are used for connecting pipelines to air sources.

[0011] Furthermore, the liquid collector pipeline is connected to liquid supply and liquid discharge equipment.

[0012] Compared with the prior art, the beneficial technical effects of the present invention are:

[0022] like Figure 1-3 As shown, a concentrating solar PVT collector includes a base 1, a support component 2 is installed on the upper end of the base 1, a concentrating component 3 is installed on the upper end of the support component 2, and a collector is installed in the vertical direction of the concentrating component 3 through a support component 2 4, and the collector includes a liquid collector 5 and an air collector 6 connected in series.

[0023] The focusing component 3 is composed of a plurality of photovoltaic panels, and the shape of the plurality of photovoltaic panels is a trough parabolic shape. This design can keep the sunlight incident on the photovoltaic panel at a roughly vertical angle, so as to concentrate the energy and reduce heat loss.

[0024] The support member 2 4 comprises a plurality of support assemblies, one end of which is circumferentially distributed around the outer periphery of the focusing member 3 and the other end of which converges at a point. When assembled, the entire assembly forms a tripod structure that stably secures the focusing member 3, offering advantages such as easy installation, simple structure, safety, and high reliability.

[0025] A plurality of limiting protrusions 601 are installed on the outer periphery of the air collector 6, and a heat dissipation component 7 is slidably installed on the outer periphery of the air collector 6. A limiting groove 704 matching the limiting protrusion 601 is installed on the inner side wall of the heat dissipation component 7. The protrusion 601 and the groove 701 cooperate with each other to achieve quick installation and convenient disassembly. The outer cover of the heat dissipation component 7 is provided with a heat exchange component 8, and the pipeline of the heat exchange component 8 is connected to the air source. The heat dissipation component 7 includes a heat dissipation body 701, and a plurality of first-level heat dissipation fins 702 are equidistantly installed on the outer periphery of the heat dissipation body 701. The ends of the first-level heat dissipation fins 702 are symmetrically distributed second-level heat dissipation fins 703. The first-level heat dissipation and then the second-level heat dissipation can effectively improve the heat dissipation efficiency, thereby avoiding the problem of low air heat exchange efficiency.

[0026] Specifically, the first-level heat sink 702 and the second-level heat sink 703 are both distributed in a spiral shape. Such a design can increase the air flow speed, improve the heat dissipation efficiency, and thus increase the heat exchange efficiency of the heat exchange component 8.

[0027] The heat exchange component 8 is symmetrically provided with air holes 801 , which are used for connecting pipelines to air sources. After heat exchange, the air holes 801 are used in areas such as building heating and product drying.

[0028] The liquid heat collector 5 pipeline is connected to the liquid supply and liquid discharge equipment. After heat exchange, it is suitable for scenes requiring a large amount of hot water.

[0029] The action process of this utility model is as follows:

[0030] First, the sunlight enters the focusing component 3 at a roughly vertical angle, concentrating the energy and converting the solar energy into thermal energy. The heat is then exchanged through the liquid collector 5 and applied to scenarios requiring a large amount of hot water. Finally, after efficient heat dissipation through the heat dissipation component 7 and heat exchange through the heat exchange component 8, the air collector 6 heats the air and uses it in areas such as building heating and product drying.

[0031] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
