Abstract
The utility model provides an inverter heat dissipation device of an external inductor, wherein the inverter heat dissipation device of the external inductor is provided with excellent heat dissipation performance. The inverter heat dissipation device of the external inductor comprises a plate. Two surfaces of the plate are respectively a connecting surface on which an IGBT module and an inductor module are arranged and fixed and a heat dissipation surface which is used for ventilation. The heat dissipation surface is provided with heat dissipation fins which extend in the same direction as the wind direction. The heat dissipation surface is provided with a high heat dissipation fin group which is located at the center and a low heat dissipation fin group which is located on both sides, wherein the heat dissipation fins in the high heat dissipation fin group are higher than the heat dissipation fins in the low heat dissipation fin group.
Description
Technical field
The utility model relates to the parts of photovoltaic DC-to-AC converter, especially the heat abstractor of its core parts IGBT module.
Background technology
IGBT module in the photovoltaic DC-to-AC converter is to small size, powerful future development, so heat dissipation problem become the bottleneck of restriction IGBT Module Reliability, and heat radiation is an important step of IGBT modular design.The operation principle of heat abstractor is mainly by convection current, if convection current is destroyed, the heat efficiency just reduces greatly.At present use maximum fin to be the aluminium section bar fin, its radiating principle is simple, and cost is low and effective.Yet in different radiator structures, the profile of the fin that design obtains differs greatly, and therefore must design the heat abstractor that can effectively solve IGBT module heat dissipating problem.
Summary of the invention
In order effectively to solve the heat dissipation problem of IGBT module, the utility model provides the inverter heat abstractor of the outstanding external inductance of heat dispersion.
The inverter heat abstractor of external inductance provided by the utility model, comprise plate, the radiating surface that two surfaces of this plate are respectively be used to the joint face that installs and fixes IGBT module and inductor module and are used for ventilating, radiating surface has the fin that extends setting with the wind direction equidirectional, radiating surface has the high groups of fins that is positioned at its central authorities and lays respectively at the low heat emission sheet group of both sides, and the fin in the high groups of fins is higher than the fin in the low heat emission sheet group.
The beneficial effect of the inverter heat abstractor of the external inductance of the utility model is: the space between the fin forms the gas channel of ventilation fan, the combination of height groups of fins has the area of dissipation of expansion and higher transverse teeth ratio, more traditional radiator has improved area of dissipation, can the fine heat dissipation problem that solves the IGBT module.
Below in conjunction with drawings and Examples the utility model is described in further detail.
