Abstract

The invention discloses a dissymmetrical radiator under compelling convection. It uses the feature that the temperature field is dissymmetrical while compelling convection. Cutting off a certain wideness of the main fan in existence at the wind entrance, and keep the original size at the wind exit. Thus, the magnetron anode is in the dissymmetrical location relative to the main fan. It is easy to produce and need not to change the product line and process. The invention can not only used for magnetron heat emission, but also used as the other radiator under compelling convection.

Description

Technical field:

[0001] The invention belongs to the fields of electronic technology and heat dissipation technology, and in particular relates to the technology that a magnetron utilizes heat dissipation fins to enhance heat dissipation. Background technique:

[0002] Magnetron is a high-power microwave source with the highest efficiency. It is characterized by high output power, high efficiency, small size, light weight and low cost. Therefore, it has been widely used not only in the military field, but also in the civilian field. has been well applied. With the development of radar, aerospace, electronic countermeasures, microwave heating and other technologies, higher requirements are put forward for magnetrons. When the magnetron is working, its anode temperature mainly comes from three aspects: the radiation from the hot cathode surface, the bombardment of electrons on the anode blades, and the eddy current generated by the high-frequency current flowing along the ano...
