Cooler

Abstract

The invention provides a cooler, which comprises a frame, an upper cover plate, a lower cover plate and a single cooling unit, wherein the upper cover plate, the lower cover plate and the frame surround to form a holding space jointly, and the single cooling unit is arranged in the holding space and comprises a vibration system and a magnetic circuit system. The vibration system comprises a first vibration film and a second vibration film. The magnetic circuit system comprises a magnetic bowl and magnets attached on the magnetic bowl. The magnets include a first magnet and a second magnet, the holding space is divided into a first outer cavity, a first inner cavity, a second inner cavity and a second outer cavity sequentially by the first vibration film, the magnetic bowl and the second vibration film, the frame is provided with a plurality of outer cavity through holes and inner cavity through holes, the outer cavity through holes and the inner cavity through holes run through the frame, the outer cavity through holes are communicated with the first outer cavity and the second outer cavity respectively, and the inner cavity through holes are communicated with the first inner cavity and the second inner cavity respectively. Compared with the prior art, the cooler is small in size, silent and power-saving, more excellent in performance and long in service life.

Description

【Technical field】 [0001] The invention relates to a cooler, in particular to a cooler used in small electronic equipment for cooling. 【Background technique】 [0002] Along with the development of society, the integration degree of modern electronic equipment is getting higher and higher, and its volume is also getting smaller and smaller, and especially small-sized portable electronic equipment is more and more subject to people's favor, as handheld computer, PSP game machine etc. However, all electronic equipment will have the problem of temperature rise after long-term operation. When the temperature of the components in the electronic equipment is too high, its working performance and service life will be affected. [0003] Therefore, general electronic equipment will be equipped with a cooler for cooling its components. The most common cooler is a cooling fan. The cooling fan blows air into the electronic equipment to reduce the temperature of the electronic equipment wh...

Problems solved by technology

[0004] However, the cooling fan in the related art has a large volume and high power consumption, and is not suitable for use in small or micro electronic devices.

Moreover, if the cooling fan of the related art works for a long time, it is easy to attach a lot of dust, so that the cooling fan emits noise when it works, resulting in a short service life.
