Description

Waterproof optimizer suitable for outdoor environment

Technical Field

The utility model belongs to the field of photovoltaic energy, and particularly relates to a waterproof optimizer suitable for an outdoor environment.

Background

A photovoltaic optimizer is a device specifically designed for use in a solar power generation system and has the main task of dynamically adjusting the operating point of a solar module so that it always operates near the maximum power point. This helps to maximize the output power of each cell assembly and reduces the effect of shadowing, fouling or temperature differences, etc. on overall system performance.

Existing photovoltaic optimizers have at least the following drawbacks in use:

1. insufficient heat dissipation capacity: photovoltaic optimizers are typically installed in confined spaces below solar panels, restricting the circulation of heat dissipating air, resulting in optimizing their temperature rise beyond the passive heat dissipating capacity. The overheating can cause the working efficiency of the electronic component to be reduced, so that the optimizer cannot achieve maximum power point tracking, and the power generation efficiency of the whole solar energy system is reduced. And the component failure and faults can be caused by the overhigh temperature, so that the stability and the reliability of the system are reduced; in extreme cases, overheat and fire hazards can also be caused, and safety threat is formed to personnel and equipment; therefore, a novel photovoltaic optimizer with an active heat dissipation function is urgently needed.

2. Without remote monitoring capability: the working state and performance of the optimizer cannot be monitored in real time by staff, and the data needs to be checked on site and manually read periodically, so that the labor and time cost are increased, delay response measures can be caused under emergency conditions (such as extreme weather, equipment faults and the like), loss and risk are increased, and therefore, a novel photovoltaic optimizer capable of being controlled remotely is urgently needed.

In this embodiment, the cooling fan 3 is an adjustable speed fan, and the rotation speed of the fan can be adjusted according to the temperature of the optimizer main body 1. The utility model introduces an active heat dissipation system in design, and comprises a heat dissipation fin made of aluminum alloy with high heat conductivity coefficient (205W/mK) and a speed-adjustable heat dissipation fan. The heat conduction performance of the aluminum alloy is more than 5 times that of many other common materials, so that the heat dissipation efficiency is greatly improved. In addition, when the temperature of the optimizer main body rises to 60 ℃, the cooling fan can automatically increase the rotating speed to 2000 rpm so as to enhance the cooling effect; when the temperature is reduced to below 40 ℃, the rotating speed of the fan is reduced to 1000 revolutions per minute, so that the energy consumption is saved. The design ensures that the working temperature of the optimizer is kept at about 50 ℃ lower than the traditional design (the normal working temperature can reach 75 ℃) under the high-temperature environment (for example, the outdoor temperature can reach 35 ℃ in summer), thereby avoiding performance reduction and fault risk caused by overheating.
