Abstract

A heat sink disclosed by the embodiment of the invention is used for a power supply device. The heat sink comprises a body and a cooling part, wherein the body comprises an installation surface, the installation surface is used for installing an electronic component, the cooling part is connected with the body and comprises a substrate and a plurality of first cooling fins, the plurality of firstcooling fins are arranged on the substrate, the substrate is connected with the body, and the plurality of first cooling fins are arranged at intervals and longitudinally extend along a direction, faraway from the body, of the substrate. The extension directions of the cooling fins of the heat sink is longitudinal, heat absorbed by the heat sink can be rapidly conducted to upper-layer air of theheat sink according to a principle that scattering hot air is conducted upwards to generate airflow, the air is blown to take away the heat by a fan, so that the purpose of temperature reduction is achieved; and when an electronic component generating a large amount of heat is arranged on the heat sink, the heat absorbed by the heat sink can be rapidly dissipated, so that the temperature of the component is controlled within a reasonable range.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a radiator, a power supply device and a microwave cooking appliance. Background technique [0002] In related technologies, frequency converters are gradually becoming a new power conversion equipment for upgrading microwave oven products, and the electronic components that make up the frequency converter are more sensitive to temperature. Excessively high temperatures will reduce the reliability of electronic components and affect the electronic components. lifespan. In order to maintain the normal operation of electronic components and ensure their service life, how to solve the heat dissipation of electronic components is a new problem. Contents of the invention [0003] The invention provides a radiator, a power supply device and a microwave cooking appliance. [0004] The radiator according to the embodiment of the present invention is used for a power supply device, ...
