Abstract

The invention discloses an MPPT control device based on heat pipe heat dissipation, which belongs to the technical field of near-space aircraft, and comprises an MPPT circuit module and a housing module; the side wall of the housing module is provided with several holes for installing plug-ins; the inner wall of the housing module is provided with There are installation holes for installing the MPPT circuit module; the bottom of the housing module is provided with mounting lugs; the outer wall of the housing module is provided with heat dissipation fins; copper heat pipes are fixed on the heat dissipation fins, and the upper and lower ends of the copper heat pipes are sealed Structure, the sealed cavity of the copper heat pipe is filled with methanol. The invention uses aluminum alloy as the structural material, and the side is provided with a weight-reducing groove, which reduces the overall strength of the device while reducing the structural weight; adopts a copper heat pipe as a means of temperature uniformity, and when the local components of the device heat up, the heat pipe can The heat is quickly transported to the cooling fins to achieve the purpose of uniform temperature, and the heat is radiated to the environment through the cooling fins.

Description

technical field [0001] The invention belongs to the technical field of near-space vehicles, and in particular relates to an MPPT control device based on heat pipe heat dissipation. Background technique [0002] In the field of near-space vehicles, stratospheric airship technology has been a hot spot in recent years, and its energy source mainly depends on photovoltaic cells. In order to use photovoltaic energy with maximum efficiency, an MPPT control device must be connected in series at the output end of the photovoltaic array. Used to track the maximum power point of a photovoltaic array. Due to the obvious advantages of the MPPT control device, it has been used in near-space vehicles, especially in stratospheric airships, and is the best choice for power tracking and conversion. [0003] Since it is essentially a power electronic power conversion device, there must be a conversion efficiency problem. At present, the conversion efficiency of the MPPT control device is abo...
