PHOTOVOLTAIC PHOTO-THERMAL HYBRID MODULE FOR COMBINED HEAT AND POWER
Technical Field
The present invention relates to the technical field of multi-purpose therapy apparatuses for
dentistry, and more particularly to a photovoltaic photo-thermal hybrid module for combined
heat and power.
Background
With the increasing maturity of photo-thermal utilization and photovoltaic utilization of
solar energy, there are more and more solar water heaters, heat collectors and photovoltaic
stations installed on roofs of various buildings. Since a lot of buildings are limited in roof area, if
the solar heat collector or water heater is installed, the photovoltaic station cannot be installed. In
view of this, the two systems are combined into one to form a hybrid system which can generate
both heat and electricity. This is the reason why the existing hybrid module is produced. The
existing hybrid module is currently under trial production and trial use in China and abroad, and
has not been actually popularized on the market. The technology is still under exploration and
has many disadvantages.
The existing technical solution is to directly lay photovoltaic cells on the surface of the
original heat absorption layer on the basis of traditional flat plate collectors. In the known
products, the ordinary photovoltaic cells are fully laid on the heat absorption layer, and there is
no thermal conducting material between the heat absorption layer and the photovoltaic cells. A
thermal insulation layer of the heat collector still uses the traditional heat absorption material. In
the formed system, water is used as a heat storage medium, and the obtained hot water is
relatively low in temperature and needs to be heated again sometimes. This system may freeze at
low temperature and cannot be used in winter. Therefore, a photovoltaic photo-thermal hybrid
module for combined heat and power is urgently needed.
Description
Summary The objective of the present invention is to solve the existing problems and provide a
photovoltaic photo-thermal hybrid module for combined heat and power.
To realize the above objective, the present invention adopts the following technical
solutions:
A photovoltaic photo-thermal hybrid module for combined heat and power includes a
photovoltaic module and a rear sealing cover plate. Two layers of alloy rims are encapsulated
and fixed between the photovoltaic module and the rear sealing cover plate. A first thermal
insulation material is filled between the alloy rims. One side of the photovoltaic module close to
the rear sealing cover plate is provided with a secondary heat exchanging structure located at the
inner side of the alloy rim. The secondary heat exchanging structure includes a first red copper
collecting pipe and a second red copper collecting pipe fixed at the inner sides of the alloy rims.
The first red copper collecting pipe and the second red copper collecting pipe are parallel to each
other, and the first red copper collecting pipe and the second red copper collecting pipe are
integrally provided with a red copper branch pipe along a length direction. One end of the red
copper branch pipe is communicated with the interior of the first red copper collecting pipe, and
the other end of the red copper branch pipe is communicated with the interior of the second red
copper collecting pipe. A second thermal conductor is filled between the red copper collecting
pipe and the red copper branch pipe and tightly bonded to the back of the aluminum-based
photovoltaic module. A second thermal insulation material is arranged between the second
thermal conductor and the rear sealing cover plate. The photovoltaic aluminum-based module
includes a heat absorption plate, a first thermal conducting colloid, a first encapsulation layer, a
large grille black silicon battery main body, a second encapsulation layer and a glass plate, which
are laminated and encapsulated. The heat absorption plate, the first thermal conducting colloid, a
first encapsulation plate, the large grille black silicon battery main body, a second encapsulation
plate and the glass plate are arranged in sequence. The large grille black silicon battery main
body includes grilles and black silicon battery pieces, which are distributed uniformly, and the
grilles and the black silicone battery pieces are arranged at intervals.
Description
Preferably, one end of the second red copper collecting pipe is integrally provided with a
liquid inlet pipe communicated with the interior of the second red copper collecting pipe. One
end of the first red copper collecting pipe is integrally provided with a liquid outlet pipe
communicated with the interior of the first red copper collecting pipe. A heat exchanging
working medium is arranged in the red copper branch pipe. The working medium is non-freezing
liquid.
Preferably, the heat absorption plate is a metal aluminum plate plated with black chrome at
intervals. The first encapsulation layer is a high-temperature-resistant EVA material. The second
encapsulation layer is a transparent membrane. The glass plate is low-carbon tempered embossed
glass.
Preferably, the second thermal conductor and the first thermal conducting colloid are
graphene-containing thermal conducting materials. The second thermal insulation material and
the first thermal insulation material are special thermal insulation materials.
Preferably, black chrome heat absorption material is arranged among the grilles. The
surface of the heat absorption material is passivated.
Preferably, the quantity of the black silicon PERC battery pieces is 60.
The present invention has the beneficial effects:
1. The secondary heat exchanging structure formed by the first red copper collecting pipe,
the second red copper collecting pipe and the red copper branch pipe is connected to the
secondary heat exchanging box for use, and then a water pump is used for circulation, so that the
high temperature generated when the photovoltaic module works can be carried away, thereby
realizing the heat radiation purpose, and the temperature of the photovoltaic module is always
kept at the required working state of 55C-60°C. The power generation efficiency can be
improved, the battery pieces can be prevented from being continuously heated up (greater than
°C), and the cycling non-freezing liquid can exchange heat with the application water in the
secondary heat exchanging box to realize the secondary heat utilization, so that the application
Description
effect is good, and the icing is prevented. The heat transfer speed can be increased by the second thermal conductor, thereby improving the heat exchanging efficiency.
2. The grilles are added among the black silicon battery pieces, and the surface of the heat absorption material is passivated, so that the absorption of the photo-thermal energy can be increased. Through the heat absorption plate, the first thermal conducting colloid and the first encapsulation plate, on the basis of guaranteeing the photovoltaic power generation, the heat can be fully absorbed and transferred, so that the idle sunning temperature on the surface of the module can be increased to 120°C from the maximum 85C of the ordinary photovoltaic module, and the normal working temperature can be stabilized at 55C -60°C for a long term.
3. By using the black silicon PERC battery pieces, the full spectral characteristics of a black silicon battery and particularly the high absorption capacity thereof for the light at the infrared band can be used, so that the absorption for the optical radiation energy can be increased, the problem that the traditional photovoltaic battery piece cannot convert about 1/4 of the sunlight composed of infrared radiation into electric energy can be avoided, and the photovoltaic conversion efficiency can be improved. Furthermore, a PERC annealing process reduces the temperature attenuation effect of the battery pieces, so that a solar module can work normally for a long term at 55C-60°C.

Description
is communicated with the interior of the second red copper collecting pipe 8. Each of the red
copper collecting pipe 4 and the red copper branch pipe 5 are filled with a second thermal
conductor 7, which is tightly bonded to the aluminum-based photovoltaic module. A second

communicated with the interior of the first red copper collecting pipe 4. A heat exchanging
working medium is arranged in the red copper branch pipe 5. The working medium is

exchanging efficiency can be improved. The non-freezing liquid is used as the thermal
conducting medium, and the secondary heat exchanging technology is used, so that system
pipelines do not freeze even in winter, and the system can be used all year round. The grilles 241

the light at the infrared band can be used, so that the absorption for the optical radiation energy
can be increased, the problem that the traditional photovoltaic battery piece cannot convert about
1/4 of sunlight composed of infrared radiation into electric energy can be avoided, and the
photovoltaic conversion efficiency can be improved.
