Abstract

The invention discloses a magnetron. The magnetron is characterized in that a heat dissipation channel extending in a first direction is arranged in a heat dissipation bracket; a tube core is arranged in the heat dissipation bracket and extends in a second direction; magnets are arranged in the heat dissipation support and located at the two ends of the tube core in the second direction, wherein the width size of the magnets in the third direction is larger than the width size of the tube core in the third direction; radiating fins are provided with central holes, wherein the tube cores penetrate through the central holes, the radiating fins are arranged in the second direction, gaps are reserved between the adjacent radiating fins, notches are formed in at least one of the two opposite side edges of the radiating fins in the third direction, and at least one part of the notches in the radiating fins are opposite in the second direction, so that the air flow circulates from the two ends of the heat dissipation support to the middle in the second direction; the notches are opposite to the central holes in the third direction, wherein the first direction, the second direction and the third direction are perpendicular to one another. According to the magnetron provided by the invention, the overall heat dissipation effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of magnetrons, and in particular relates to a magnetron. Background technique [0002] The magnetron, the English name is Magnetron, was developed between 1936 and 1937 and was applied in the market in 1939. It is a device that can generate microwave energy. The "magnetic" in the magnetron refers to the magnetic field, and the "tube" refers to the diode. Therefore, the "magnetron" actually places the diode in the magnetic field. Under the combined action of the magnetic field and the generated electric field, the tube The process by which electrons convert energy acquired in an electric field into microwave energy. Magnetron has many characteristics such as low cost, small size, high power and high efficiency, and has been widely used. Magnetron is a vacuum electron tube that generates microwaves. Because of its high oscillation efficiency and high microwave output power, it is widely used as a microwave s...
