Magnetron drive power supply for industrial microwave equipment

Abstract

The invention discloses a magnetron drive power supply for industrial microwave equipment, which comprises a wire cable, a circuit board, components and an oil tank, wherein the wire cable is electrically connected with the circuit board; the components are fixed on the circuit board and comprise a transformer and a power component; the oil tank comprises a tank body and a cover board; the circuit board and the components are soaked in oil of the oil tank; and heat is transferred to the oil tank by the oil. The circuit board and the components are sealed in the oil tank and free from outside pollution; the heat-dissipation effect cannot be reduced due to dust accumulation; electrical potential safety hazards cannot be generated; the heat-dissipation effect of the cooling oil is good; and the power supply easily meets safety requirements.

Description

[technical field] [0001] The invention relates to a magnetron drive power supply for microwave equipment, in particular to a magnetron drive power supply for industrial microwave equipment. [Background technique] [0002] The existing industrial microwave equipment magnetron drive power uses high-frequency electronic transformers to replace traditional industrial frequency transformers. High-frequency electronic transformers have the characteristics of high efficiency, good reliability, and wide operating voltage. However, the high-frequency electronic transformers and semiconductor devices The high temperatures generated require efficient cooling. The traditional magnetron drive power supply for industrial microwave equipment adopts an open air-cooled heat dissipation method. The disadvantage is that dust is easy to accumulate on the electronic components, which not only reduces the heat dissipation effect, but also easily generates electrical safety hazards, resulting in e...

Problems solved by technology

The traditional magnetron drive power supply for industrial microwave equipment adopts an open air-cooled heat dissipation method. The disadvantage is that dust is easy to accumulate on the electronic components, which not only reduces the heat dissipation effect, but also easily generates electrical safety hazards, resulting in electrical accidents; In addition, Under the air-cooled heat dissipation method, the circuit board is arranged horizontally, which increases the projected area in the Z-axis direction, and the area occupied by the power supply is large.
