Description

Technical Field

[0001] The utility model relates to the technical field of solar panel waste heat utilization, in particular to a solar photovoltaic power generation waste heat utilization device. Background Art

[0002] Solar panels generate a lot of heat during operation. If the heat is not effectively dissipated, the temperature of the solar panels will be too high, which will affect their working efficiency and service life.

[0003] In the prior art, three methods are commonly used: air convection heat dissipation, water cooling and heat pipe heat dissipation. Air convection heat dissipation mainly uses a fan to blow air to the backlight side of the solar panel, and uses air convection to cool the solar panel, but the heat dissipation effect is average. Water cooling and heat pipe heat dissipation have better heat dissipation effects on solar panels, but require the layout of a more complex piping system and regular maintenance, resulting in increased costs for solar panels.

[0004] Based on the above situation, air convection cooling uses a fan to blow air to cool the back of the solar panel, and the heat dissipation effect is poor; water cooling and heat pipe cooling require complex pipelines and maintenance, and these three methods cannot effectively utilize the waste heat generated during the operation of the solar panel. Therefore, the present application provides a solar photovoltaic power generation waste heat utilization device. Utility Model Content

[0005] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a solar photovoltaic power generation waste heat utilization device, which can dissipate the heat generated during the operation of the solar panels, and use the waste heat for indoor heating. When the outdoor temperature is too low, it can also heat the solar panels to avoid damage caused by too low temperature of the solar panels, thereby adapting to year-round use in plateau areas.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A solar photovoltaic power generation waste heat utilization device is provided, comprising a solar panel and an air chamber, wherein a plurality of legs are connected to the backlight side of the solar panel, the other ends of the legs are fixedly connected to the ground, the air chamber is fixedly connected to the backlight side of the solar panel, an air inlet pipe and an air outlet pipe are respectively connected to the top and bottom of the air chamber, an air supply device is connected to the air inlet pipe, and the other end of the air outlet pipe extends into the room.

[0008] Furthermore, a plurality of heat-conducting pins are arranged on the backlight side of the solar panel, and two ends of the heat-conducting pins extend toward the inside of the air chamber and the inside of the solar panel respectively.

[0009] Furthermore, a heat conducting plate is fixedly mounted on the backlight side of the solar panel, and the heat conducting pins are fixedly mounted on the heat conducting plate.

[0010] Furthermore, a purge pipe is connected to the side of the air inlet pipe, and a plurality of purge bronchial pipes are connected to the purge pipe. The purge bronchial pipes extend toward the middle of the light-facing side of the solar panel, and valves are respectively provided on the air inlet pipe and the purge pipe.

[0011] Furthermore, a filter cartridge is provided on the air inlet pipe.

[0012] Furthermore, the air inlet pipe and the air outlet pipe are respectively connected to the air chamber through a plurality of air inlet bronchial pipes and air outlet bronchial pipes.

[0013] Furthermore, the legs include a first leg and a second leg, the first leg is rotatably mounted on the backlight side of the solar panel, the second leg is slidably connected to the first leg, and the second leg is rotatably connected to a base on the ground.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The solar photovoltaic power generation waste heat utilization device of the utility model uses air supply equipment to send outdoor air with lower temperature into the air chamber, removes the accumulated heat on the backlight side surface of the solar panel, and continuously operates the air supply equipment to transport the air with increased temperature into the room through the air outlet pipe. In this way, while dissipating the heat generated during the operation of the solar panel, the waste heat is used to heat the room, which is suitable for summer use in plateau areas with lower temperatures throughout the year.

[0016] 2. The solar photovoltaic power generation waste heat utilization device of the utility model example has the other end of the outlet pipe extending into the room. Therefore, when the outdoor temperature is too low, the temperature generated by the indoor boiler is used to increase the indoor temperature. The hot air enters the air chamber from the outlet pipe, thus avoiding damage to the solar panel at low temperature and adapting to winter use in plateau areas.

[0017] 3. The solar photovoltaic power generation waste heat utilization device of the utility model example uses heat-conducting needles to conduct the heat generated during the operation of the solar panel to the backlight side of the solar panel, so as to fully dissipate the heat of the solar panel and utilize the waste heat, thereby increasing the use effect of the equipment.

[0018] 4. The solar photovoltaic power generation waste heat utilization device of the utility model switches the opening and closing states of the air intake pipe and the purge pipe, so that in rainy and snowy weather conditions, the residual rainwater on the light-facing side of the solar panel can be purged, avoiding manual cleaning operations and being convenient to use.

[0019] 5. The solar photovoltaic power generation waste heat utilization device of the utility model example uses a filter cartridge to filter the air entering the air chamber from the air inlet pipe to prevent dust and other debris from entering the interior of the device, thereby improving the cleanliness of the interior of the device and extending the service life of the device.

[0020] 6. The solar photovoltaic power generation waste heat utilization device of the utility model example utilizes multiple air inlet bronchus and air outlet bronchus, so that air passes into the air chamber and is discharged from the air chamber through the air inlet bronchus and the air outlet bronchus, thereby increasing the contact effect between the air and the heat conductive needles.

[0034] The light intensity in plateau areas is high. Being exposed to high-intensity light for a long time will have an impact on human health. Therefore, it is necessary to isolate the light. Usually, walls and other objects are used to block the light and reduce the intensity of light entering the room. However, this also results in the inability of light radiation to effectively increase the indoor temperature.

[0035] Start the air supply device 24, such as a booster duct fan, to deliver the air with lower outdoor temperature into the air chamber 21 to remove the accumulated heat on the backlight side surface of the solar panel 1; then, continue to operate the air supply device 24 to deliver the air with increased temperature to the room through the outlet pipe 23, so as to dissipate the heat generated during the operation of the solar panel 1 and use the residual heat to heat the room, so as to adapt to the summer use in plateau areas with lower temperature throughout the year.

[0036] In addition, since the other end of the air outlet pipe 23 extends indoors, when the outdoor temperature is too low, the temperature generated by the indoor boiler can be used to increase the indoor temperature, and the hot air enters the air chamber 21 from the air outlet pipe 23 to avoid damage to the solar panel 1 due to low temperature, which is suitable for winter use in plateau areas. At this time, the air supply device 24 is in a closed state, and a small amount of air can be discharged to the outside from the air inlet pipe 22 to maintain normal air circulation.

[0040] In order to improve the thermal conductivity of the heat conducting needle 31, Figure 2 As shown, the air inlet pipe 22 and the air outlet pipe 23 are connected to the air chamber 21 through multiple air inlet bronchus and air outlet bronchus respectively, and the air is passed into the air chamber 21 and discharged from the air chamber 21 through the air inlet bronchus and the air outlet bronchus, thereby increasing the contact effect between the air and the heat conductive needle 31, thereby improving the thermal conductivity of the heat conductive needle 31.

The difference between this embodiment and the first embodiment is that: Figure 1 As shown, in this embodiment, the legs include a first leg 11 and a second leg 12. The first leg 11 is rotatably mounted on the backlight side of the solar panel 1, the second leg 12 is slidably connected to the first leg 11, and the second leg 12 is rotatably connected to a base 13 on the ground.
