Title:
【発明の名称】マグネトロンの放熱フィン構造
Document Type and Number:
Japanese Patent JP2812846
Kind Code:
B2
Abstract:
This invention relates to a radiation fin structure of a magnetron and a magnetron which includes such a structure. The fin structure is capable of effectively radiating heat at a high temperature produced during oscillation of the magnetron. The magnetron can be used to generate microwaves which can be emitted into a cavity of a microwave oven. The radiation fin is capable of reducing a separation region in the rear of an anode of the magnetron by guiding cold air which passes through a cooling section of the magnetron to the back side of the anode to generate turbulence within the cooling section. The radiation fin structure incorporated in this invention includes a plurality of pairs of confronting protrusions formed at opposite side portions of the radiation fin. The fins are arranged externally of the magnetron anode equally spaced-apart from one another to guide cold air to the back side of the anode.
