Abstract
The utility model relates to a transformer of a microwave oven. The iron core comprises an iron core (1), wherein a plurality of heat dissipation devices are arranged on the iron core (1). The heat dissipation device is a heat dissipation fin. The utility model discloses owing to adopt and be equipped with a plurality of heat abstractor at the iron core facial make-up, the radiating effect is good, can reduce the temperature rise, does not need the iron core volume of increase transformer moreover to increase heat radiating area, the cost of transformer that has so significantly reduced.
Description
Technical field
The utility model is a kind of micro-wave oven transformer, belongs to the improvement technology of micro-wave oven transformer.
Background technology
At present, the high voltage source in the microwave oven product generally is made of high-tension transformer, high-voltage capacitance, high-voltage diode coupling, and this structure has guaranteed that high voltage source has bigger internal resistance, thereby has stablized the operating voltage of magnetron.To be microwave system be converted to the first step of electromagnetic energy by electric energy with high-tension transformer, the structure of high-tension transformer and with the matching status of high-voltage capacitor, directly have influence on the efficient of whole power-supply system.The high-tension transformer iron core mostly is the shell-type structure of " I " type, be formed by stacking by the high-quality cold-reduced silicon sheet, and iron core has the magnetic shunt structure that makes the micro-wave oven transformer secondary output voltage stable, and elementary, secondary and three coils of filament of winding part are respectively in center pinch.High-tension transformer owing to the existence of copper loss and iron loss, can produce higher temperature rise when work, usually, even if under the condition that adopts forced air cooling, still need increase the core volume of transformer, to increase area of dissipation, reduce temperature rise, but meanwhile increased the cost of transformer greatly.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of good heat dissipation effect, the micro-wave oven transformer that can reduce temperature rise, reduces cost.
The utility model structural representation comprises iron core (1) as shown in Figure 1, 2, wherein is equiped with some heat abstractors on the iron core (1).
Above-mentioned heat abstractor is a fin.
Above-mentioned iron core (1) top is equiped with fin (2), and both sides are equiped with fin (3), (4).
Above-mentioned fin (3), (4) lower end are packed on the micro-wave oven baseboard by connector respectively.
Above-mentioned fin (3), (4) upper end are provided with grab (31), (41), and fin (3), (4) tightly are stuck in the two ends of fin (2) by grab (31), (41).
Above-mentioned fin (3), (4) upper end are packed in the two ends of fin (2) respectively by connector.
Above-mentioned connector is screw or screw.
