Description

Technical Field

[0001] The present invention relates to the technical field of reactor heat dissipation, and in particular to a reactor cooling structure and method. Background Art

[0002] Reactors, also known as inductors, are widely used in circuits. Due to electromagnetic induction, they exhibit a certain degree of inductance, which acts to prevent current changes. The lifespan of a reactor is defined as the time it maintains normal operation under rated load. The lifespan of a reactor is determined by the materials used to manufacture it. Reactors are made of two main types of materials: metal and insulating. Metals are heat-resistant, while insulating materials, exposed to high temperatures, electric fields, and magnetic fields for long periods of time, gradually lose their mechanical and insulating properties, resulting in brittleness, reduced mechanical strength, and electrical breakdown. Higher temperatures accelerate the decline in the mechanical and insulating properties of insulating materials, and the higher the moisture content, the faster the aging of insulating materials. Reactors require timely heat dissipation during use.

[0003] The reactor cooling device disclosed in the existing patent publication number CN111033652B includes a shell, a reactor and a rotating body. The reactor is arranged in the shell, and the rotating body is rotatably arranged below the reactor in the shell. The rotating body and the reactor are arranged so that at least a portion overlaps in any direction of the rotation radius of the rotating body. A portion of the rotating body is immersed in the liquid refrigerant accumulated in the shell, and the liquid refrigerant splashed by the rotating rotating body contacts the reactor to cool the reactor. The reactor is arranged along a portion of the inner wall surface of the shell, and a refrigerant flow path is formed between the relative wall surface opposite to the reactor in the rotation radius direction of the rotating body and the side surface of the reactor opposite to the relative wall surface, that is, the relative side surface. The liquid refrigerant splashed by the rotating body flows in the refrigerant flow path.

[0004] The above cooling device can cool the reactor, but the refrigerant is splashed onto the reactor during cooling. In practical applications, this is not conducive to the installation and use of the reactor and needs to be improved. To address the above problems, a reactor cooling structure and method are proposed. Summary of the Invention
