Problems solved by technology

At present, most radiators use passive heat dissipation to dissipate heat. Most passive radiators have a large volume, and the volume of the radiator restricts the development of related products to a certain extent. If a radiator can be provided to reduce the volume of the radiator Small, the products in related fields will no longer be restricted by radiators and wait for rapid development

Abstract

The invention discloses a synthetic jet radiator which comprises a heat source, wherein the upper side of the heat source is provided with a heat radiating sheet, wherein the upper side of the heat radiating sheet is provided with a plurality of fins, a plurality of synthetic jet devices are installed between the fins, each synthetic jet device comprises a shell body with a cavity, the upper side of the shell body is provided with a nozzle, the lower end of the shell body is provided with a vibrating film, the lower side of the vibrating film is provided with a piezoelectric sheet. The radiator is characterized in that the radiator has the advantages of being reasonable in structure, simple in structure and use, convenient to use, high in reliability, small in occupied area, light in weight, high in durability, big in heat dissipating capability, free from any noise, low in production cost and be popularized conveniently and achieving active heat dissipation.

Description

technical field [0001] The invention belongs to radiators, in particular to a synthetic jet radiator capable of realizing active heat dissipation. Background technique [0002] A radiator is a device used to conduct and release heat. Depending on the object of heat dissipation, the heat dissipation methods are also different. Some use heat sinks for natural cooling, and some use fans for air cooling. For different application fields, the requirements for heat dissipation are different, and the structure of the heat sink also has very high requirements for the application occasions. At present, most radiators use passive heat dissipation to dissipate heat. Most passive radiators have a large volume, and the volume of the radiator restricts the development of related products to a certain extent. If a radiator can be provided to reduce the volume of the radiator Small, the products in related fields will no longer be restricted by radiators and wait for rapid development. ...
