Description
Technical Field
The invention belongs to the technical field of near space vehicles, and particularly relates to an MPPT control device based on heat pipe heat dissipation.
Background
In the field of near space aircrafts, stratospheric airship technology is a development hotspot in recent years, energy sources of the technology mainly depend on photovoltaic cells, and in order to utilize photovoltaic energy at the maximum efficiency, an MPPT control device is generally connected in series at the output end of a photovoltaic array and used for tracking the maximum power point of the photovoltaic array. Due to the obvious advantages of MPPT control devices, it has been applied in near space vehicles, particularly stratospheric airships, as a second choice for power tracking and conversion.
Since the MPPT control device is essentially a power electronic power conversion device, the conversion efficiency is inevitably problematic, and at present, the conversion efficiency of the MPPT control device is about 95%, so that 5% of power is lost, and the power is radiated to the environment in the form of heat. For stratospheric airship, the photovoltaic array is large in scale, and is generally realized by adopting a distributed design, namely, the photovoltaic array is divided into a plurality of sub-arrays, and each sub-array is independently connected with an MPPT control device in series. Even so, the processing power of each MPPT controller is about 2kw, and the heat generation power of each MPPT controller is about 100w or less calculated by 5% heat loss, which is fatal to the MPPT controller with concentrated power density if the heat dissipation measure is not proper. For special application environments such as adjacent space, not only the heat dissipation power but also the technical state and environmental parameters of the heat dissipation surface are considered, the heat dissipation design is a relatively complex process, has certain technical difficulty, and needs to consider unified design in the aspects of heat dissipation, light weight and the like.
