Abstract
The utility model relates to a microwave energy output of a magnetron, comprising of an A side tube, an insulating ring and an antenna cap connected successively on a pipe core energy output end. The utility model is characterized in that nickel coating is positioned on the inner and outer wall of the A side tube; copper layer is positioned on nickel coating of the inner wall and/or the outer wall. Nickel coating and copper layer is positioned respectively on the inner and outer wall of the A side tube in proportion. First of all, the nickel coating is in the proportion of 1Mum to 3Mum; then the copper layer is in the proportion of 5Mum to 8Mum in order to prevent oxidation and reduce high-frequency loss and improve the output power of the magnetron, then eventually improve the work efficiency of the microwave oven. The utility model has the advantages that for in the same frequency the skin efficiency of different metal is the same, while the resistivity of copper is smaller than the resistivity of nickel and the antioxidation of nickel is stronger than the antioxidation of copper, therefore the nickel coating and copper layer in the proportion can reduce high-frequency loss effectively and improve the output power of the magnetron and at the same time prevent oxidation.
Description
Technical field
The utility model relates to the microwave energy follower of a kind of magnetron, particularly a kind of magnetron.
Background technology
In the design of magnetron, the output of microwave energy is very important, the size design of transmission line is most important in the energy follower, under the rational prerequisite of size design, also to consider the high-frequency loss of material, in the former specification requirement, people are provided with 5 μ m～8 μ m on the inside and outside wall of A side pipe of magnetron energy output nickel dam reaches anti-oxidation purpose.
As everyone knows, alternating current has skin effect, and skin effect makes the resistance of conductor increase indirectly, and its energy thermal losses also increases thereupon.In the wave band of high bands such as microwave, skin effect is very obvious, much higher (resistivity of copper is 1.678 Ω .m 20 ℃ the time and the resistivity of nickel is than conventional conductive copper, the resistivity of nickel is 6.84 Ω .m), the energy thermal losses that skin effect causes is very big, temperature rise is also increased thereupon, has directly influenced the power output and the heat dispersion of magnetron.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of microwave energy follower of simple and reasonable, cost of manufacture is low, the energy thermal losses is low, limit of temperature rise is low, output rating is high magnetron, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of microwave energy follower of magnetron, be included in A side pipe, dead ring and antenna cap that tube core energy output connects successively, the inside and outside wall of A side pipe is provided with nickel coating, its architectural feature is that the nickel coating of inwall is provided with copper plate, and/or the nickel coating of outer wall is provided with copper plate.
Nickel coating and copper plate are set respectively on the inside and outside wall of the A side pipe in the utility model in proportion, nickel coating 1 μ m～3 μ m at first, follow copper plate 5 μ m～8 μ m again, reach anti-oxidation and reduce high-frequency loss, improve the power output of magnetron, reach the purpose that improves the microwave oven operating efficiency at last.
Because under same frequency, the skin effect of different metal is consistent, but the resistivity of copper is more much smaller than nickel, the non-oxidizability of nickel is stronger than copper simultaneously, nickel plating in proportion, copper layer can effectively reduce high-frequency loss, improve the power output of magnetron, and reach the purpose of anti-oxidation simultaneously.
