technical field

The utility model relates to the technical field of power generation equipment, in particular to a photovoltaic power generation device.

Background technique

In today's world, the problem of environmental pollution is becoming more and more serious, and energy is gradually in short supply. Solar energy is attracting more and more global attention and recognition due to its unique advantages such as abundant reserves, wide distribution, and green environmental protection. In a photovoltaic power generation system, solar energy is converted into electrical energy through photovoltaic modules, and electrical energy is an advanced energy source that is easier to utilize, transmit and distribute. Usually, the solar cell components are combined according to the local climate conditions, geographical environment, light resources and other factors, and the photovoltaic components in the photovoltaic power generation system are combined in a specific arrangement and orientation. The most typical ones are square arrays and circular arrays. There are generally two types of support structures for the arrangement of photovoltaic modules and fixed spacing: steel structure and aluminum alloy structure. It is also common to mix the two, so as to better collect light energy for power generation, so that the entire photovoltaic power generation system can work at maximum power point.

However, the photovoltaic power generation device is always in the outdoor environment, and the light-receiving surface of the photovoltaic cell panel is exposed to wind and rain, which seriously affects the service life, and at night, the existing photovoltaic power generation device will not put away the photovoltaic cell panel, so the increase The probability of damage to the photovoltaic panel is reduced, which affects the service life of the device.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present utility model, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the relative positional relationship, movement conditions, etc. between the components shown in the figure below are changed, if the specific posture changes, the directional indication will also change accordingly.

In addition, the technical solutions of the various embodiments can be combined with each other, but it must be based on the realization of those skilled in the art. When the combination of technical solutions is contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist , also not within the scope of protection required by the utility model.

As shown in Figure 1, a photovoltaic power generation device includes a solar cell panel 1, and also includes a heat dissipation support 2, the main body of the heat dissipation support 2 is flat, and the solar cell panel 1 is fixed on the heat dissipation plate; at the same time Fixing bolts are arranged around the solar panel to strengthen the close contact between the solar panel 1 and the cooling plate.

Since the ideal operating temperature of the solar panel is 25°C, the power of the solar panel will decrease as the temperature rises, and if the temperature is too high, it will also affect the life of the battery.

Therefore, this device adds a heat dissipation support 2 on the back of the battery board 1, especially the contact of the battery board 1 is a heat dissipation plate structure. The heat is dissipated, reducing heat accumulation on the battery board 1 and relatively prolonging its service life.

The heat dissipation support 2 and the back of the solar cell panel 1 are bonded together with heat-conducting adhesive to improve the heat transfer effect between the two, and to conduct the heat on the solar cell panel 1 as soon as possible.

The back side of the heat dissipation plate of the heat dissipation support 2 is provided with a heat dissipation fin 21 to enhance the heat dissipation effect.

The device also includes a water-cooling channel 3, the heat sink 21 is buried in the water-cooling channel 3, and the heat on the heat sink is quickly exported through the water cooling method. As shown in Figure 1, cold water is injected from the water inlet 31 at the bottom , gradually exchanges heat with the cooling fins 21 in the water cooling channel 3 , and then leads out from the water outlet 32 .

The device has simple structure and good heat dissipation effect, reduces the temperature of the battery board 1 during operation, improves its working efficiency and prolongs its service life.
