A wrapped heat sink and an inductance efficient heat dissipation structure

Abstract

The invention discloses a cladding type radiator and an inductive high-efficiency heat dissipation structure. The cladding type radiator comprises a heat dissipation main body, the heat dissipation main body comprises an accommodation cavity, and the bottom of the accommodation cavity is provided with an opening for placing an electrical appliance component therein. The cladding type radiator further comprises a plurality of first radiating fins, the heat dissipation main body comprises a first outer wall, the first radiating fins extend outwards in a mode of being vertical to the first outer wall, and along the direction vertical to the first radiating fins, the closer the first radiating fins are to the central portion of the direction, the heights extending outwards from the first outer wall are larger. The invention simultaneously provides an inductive high-efficiency heat dissipation structure using the cladding type radiator. The cladding type radiator and the inductive high-efficiency heat dissipation structure can be adapted to harsh environment, are high in protection grade and high in heat dissipation efficiency and can resist water accumulation and dust accumulation.

Description

technical field [0001] The invention relates to a heat sink and an inductor efficient heat dissipation structure, in particular to a wrap-type radiator with good heat dissipation performance and an inductor high-efficiency heat dissipation structure using the wrap-type radiator. Background technique [0002] With the rapid development of industrial technology, large-scale power electronic equipment is more and more widely used in various industries, and the power level and power density are also getting higher and higher, so the requirements for power electronic components are also getting higher and higher. For example, combiner boxes are used in solar photovoltaic power generation systems. In order to prevent the heat of power devices and inductors from interacting with each other, more and more combiner boxes change the inductance from built-in to external. However, combiner boxes are usually used in environments such as deserts. In relatively harsh places, the radiator n...

Problems solved by technology

For example, combiner boxes are used in solar photovoltaic power generation systems. In order to prevent the heat of power devices and inductors from interacting with each other, more and more combiner boxes change the inductance from built-in to external. However, combiner boxes are usually used in environments such as deserts. In relatively harsh places, the radiator needs to withstand the erosion of wind, sand and rain all year round. Due to the unreasonable structural design of the existing radiator, it is easy to accumulate water or dust on the surface of the radiator. Once the radiator fin is blocked, the heat dissipation effect will be reduced. Big discount

In addition, the radiator fins of the prior art radiators are unreasonably designed. The radiator fins located in the middle position, because the air flow will be blocked by the radiator fins on both sides, so it often cannot form convection well and becomes a blind area, and due to the heat accumulation problem , the heat sink in the middle tends to accumulate more heat; and the current heat sink cannot play a good guiding role in the airflow (natural wind or wind blown by the fan), resulting in that the airflow cannot circulate on the heat sink and bring The heat on the heat sink leads to low heat dissipation efficiency and cannot protect power devices such as inductors. The application of heat sinks has been greatly challenged.
