Description

Light-gathering solar cell panel heat utilization device

Technical Field

Background

The solar cell panel is an rare green energy source due to environmental protection and energy conservation, and the application of the solar cell panel is more and more extensive. Solar panels are generally classified into general light-receiving types and light-collecting types. Wherein the light receiving surface of the light receiving type solar cell panel is positioned at the upper end in application, and sunlight directly acts on the light receiving surface to generate electric energy; the solar cell panel has a limited sunlight intensity per unit area of the light receiving surface due to the scattered sunlight, and thus the power generation capacity is not very high. As shown in fig. 1, the general structure of the concentrating solar cell panel includes a semi-arc-shaped collecting mirror 14 with a certain length in the transverse direction, a mounting bracket 15, a heat dissipation mechanism, etc., the solar cell panel 16 is mounted on the upper end of the bracket 15 and located at an upward focusing point of the collecting mirror 14, when in use, light irradiates on a light receiving surface of the collecting mirror 14, and the light is focused by the collecting mirror 14 and then is aligned with the solar cell panel 16 which is transversely distributed on the upper end of the bracket 15 and the light receiving surface is located at the lower part; because the light rays acting on the light receiving surface are strong, the concentrating solar cell panel has higher-density power generation capacity, and therefore the concentrating solar cell panel becomes the mainstream of solar cell application more and more.

As shown in fig. 1, when the concentrating solar panel is operated, the temperature of light rays focused on the solar panel 16 is high (up to hundreds degrees), and thus the service life of the solar panel is shortened if the solar panel is not cooled by a heat radiation mechanism (particularly in summer, if the surface temperature of the solar panel 16 is high, and if it suddenly rains, the solar panel may be rapidly contracted to cause a destructive crack or the like). The existing heat dissipation mechanism of the concentrating solar panel 16 generally installs a cooling pipe 2 (which is tightly attached to the upper end face of the solar panel 16 to absorb heat) in a serpentine distribution at the upper end of all the solar panels, and in application, a circulating pump 1 (the working of the circulating pump 1 is generally controlled by a time control switch or a light control circuit and works in a required daytime period or at a strong light) continuously pumps cooling liquid (generally antifreeze) in a cooling tank 3 of the heat dissipation mechanism out of a liquid outlet pipe, enters the cooling pipe 2 to absorb heat generated by the solar panel 16 when being illuminated, and then flows back into the cooling tank through a liquid inlet pipe of the cooling tank 3 of the heat dissipation mechanism, and after absorbing the heat in the process, the cooling liquid dissipates the heat to the outside through a radiator of the cooling tank to complete the heat dissipation circulation of the refrigerant liquid. In fact, the highest temperature of the cooling liquid can reach hundreds of degrees after absorbing the heat of the solar cell panel, so that the energy waste can be caused by the heat absorbed by the cooling liquid emitted by the existing heat dissipation mechanism, the energy waste is mainly embodied in that the heat dissipation fan or the electric condenser of the cooling tank 3 can use electric energy in the heat dissipation of the radiator, the heat contained in the cooling liquid is discharged in vain, and the heat energy is not effectively utilized. Based on the above, it is necessary to provide a device capable of effectively utilizing the heat energy absorbed by the cooling liquid of the heat dissipation mechanism to save energy.

Fig. 1, 2 and 3 show that the storage battery G1 is charged while the solar cell panel 16 generates electric energy, so that the novel solar energy storage battery can be continuously used in rainy days and the like. During power generation of the light-gathering solar cell panel 16, after the circulating pump 1 works with electricity (the circulating pump 1 works generally under the control of a time control switch or a light control circuit and works in a required daytime period or under the control of strong light), cooling liquid (generally antifreeze) in the cooling tank 3 of the heat dissipation mechanism is continuously pumped out from the liquid outlet pipe 32 to enter the cooling pipe 2 to absorb heat generated by illumination of the solar cell panel 16, then the cooling liquid flows back into the cooling tank 3 through the liquid inlet pipe 31 of the cooling tank of the heat dissipation mechanism, and the cooling liquid absorbs the heat in the process and dissipates the heat to the outside through the radiator of the cooling tank 3, so that the cooling requirement of the solar cell panel 16 is met. When the temperature in the water tank 132 is lower than 55 ℃, the internal contact of the temperature control switch W is closed, so that a power supply output by the positive electrode of the storage battery G1 enters the positive power supply input end of the relay K through the temperature control switch W with the closed contact, the relay K is electrified to attract the control power supply input end and the normally open contact end to be closed, the electromagnetic valves DC2 and DC3 are electrified, the valve core in the electromagnetic valve DC2 is opened, and the valve core in the electromagnetic valve DC3 is closed; thus, after the circulation pump 1 continuously pumps the cooling liquid in the cooling tank 3 of the heat dissipation mechanism out of the liquid outlet pipe 32, the cooling liquid enters the heat release pipe 132 through the electromagnetic valve DC2 opened by the internal valve core via the cooling pipe 2, flows out of the left lower end of the water tank (the left lower end of the heat release pipe 132) and enters the liquid inlet end of the circulation pump 1 via the first one-way valve 51 (since the one-way valve 52 is reversely closed, the cooling liquid cannot flow back into the cooling tank 3), then enters the cooling pipe 1 from the liquid outlet end of the circulation pump 1, and then flows into the heat release pipe 131 via the electromagnetic valve DC2, after absorbing heat, the cooling liquid continuously flows into and flows out of the heat release pipe 131 located in the water tank 131, releases heat to the tap water in the water tank 131, heats the water, and a user can normally use the hot water after opening the water valve connected with the. Meanwhile, the temperature of the cooling liquid after heat release of the tap water is lower after the cooling liquid absorbs heat through the tap water and flows back into the cooling pipe 2, so that the heat dissipation requirement of the solar cell panel 16 is effectively met, and the solar cell panel 16 can achieve better power generation performance.

Fig. 1, 2 and 3 show, in the electricity generation of light-concentrating solar cell panel 11, when the temperature is higher than more than 55 ℃ in water tank 132, the inside contact of temperature detect switch W opens a way, like this, the anodal output's of battery G1 power no longer gets into relay K anodal power input end, relay K loses the electricity and no longer attracts the dress, its control power input end and normally open contact end open a way, and then solenoid valve DC2, DC3 loses the electricity, the inside case of solenoid valve DC2 is closed, the inside case of solenoid valve DC3 is opened. Like this, circulating pump 1 resumes constantly to take out the cooling liquid in cooling tank 3 with heat dissipation mechanism from drain pipe 32 and gets into the cooling tube 2 and absorb the heat that solar cell panel 16 produced by the illumination, then in the feed liquor pipe 31 backward flow income cooling tank 3 of solenoid valve DC3 and the heat dissipation mechanism cooling tank that the case was opened (because check valve 51 is reverse to ending, the cooling liquid can not get into heating tube 132), get into in the cooling tube from circulating pump 1 liquid outlet end again, the cooling liquid dispels the calorific capacity to the external world through the radiator of cooling tank 3 behind the in-process absorbed heat, the cooling needs of solar cell panel 16 have been satisfied. In this is novel, when the water is many in the water tank 131, two inside contacts of water level switch K are opened a way, and first solenoid valve DC1 can not be got into the electricity so, and the running water does not get into in the water tank. When the water in the water tank 131 is reduced to a certain level, the floating ball of the water level switch K moves to the bottom dead center, then, two contacts inside the water tank are closed, and then the 24V power enters the positive power input end of the electromagnetic valve DC1, and the electromagnetic valve DC1 is powered on, so that tap water enters the water tank 131 through the electromagnetic valve DC1 with the opened valve core, and water is filled into the water tank 131. When the water level in the water tank 131 is sufficient again, the two contacts inside the water level switch K are opened again, and then the first solenoid valve DC1 loses power, and the tap water does not enter the water tank 131 any more. Through the aforesaid, this novel can effectively guarantee to keep high water level (from water level about the upper end 5cm in the water tank) in the water tank 131, satisfy absorption coolant liquid heat energy to provide hot water needs as much as possible for the user. This novel relief valve 8 is closed when water tank 131 internal pressure is low, and the case can open discharge pressure automatically (be higher than 0.25MPa and open) behind the high water tank 131 internal pressure increase of temperature, prevents that the pressure is too high to lead to the water tank 131 to damage. This is novel under relevant equipment combined action, can fully guarantee under the solar cell panel working property prerequisite, can also reach the energy can be saved to convenient purpose has been brought for the user. Relay K is a DC36V relay.
