COOLING DEVICE USING INTERNAL ARTIFICIAL JETS

摘要

FIELD: heating.SUBSTANCE: invention relates to a cooling device that uses artificial jets. The device (1) of the artificial jet cooling for cooling an object (5) comprises a converter (10) adapted so as to produce the waves of speed and a chamber (4) adapted with the ability to receive the waves of speed through the actuated opening (8). The chamber (4) is sufficiently large in order to create at the actuated opening (8) the inner artificial jet inside the chamber (4). In addition, the chamber (4) is made with the ability to contain an object (5), thereby enabling cooling of the object (5) by the inner artificial jet. This arrangement generally allows the multipurpose use of existing chamber comprising the object to be cooled and for its original purpose (e.g. a reflector in a lamp or a LED backlight module) and as a chamber for producing internal artificial jets therefore the cooling device typically requires virtually no extra space and weight and can be provided at low cost.EFFECT: improved active cooling by forced convection.14 cl, 6 dwg
