RADIATOR DEVICE Russian patent published in 2008 - IPC H05K7/20 F28D15/02 

FIELD: electronics.

SUBSTANCE: invention pertains to electronics and specifically to heat transfer and can be used in aircraft-borne equipment for increasing efficiency of heat transfer and protection from electromagnetic interference. The radiator device is in contact with a heat-loaded element and has several lamellar thermal plates, each of which has a heat absorption part, in contact with the surface of the heat loaded element, and a heat releasing surface, which is a continuation of the heat absorption part. The thermal plates are arranged in piles, in which the heat absorption part of the plates forms the centre of the pile of the thermal plates. The device also has a pair of squeezing blocks between the heat absorption parts of the pile of thermal plates and squeezing the heat absorption part of the plates. The heat releasing part of the plates is such that, after forming the plates, a structure is formed, in which the heat releasing parts of the plate are parallel to each other, and the heat absorption parts form a closed space on all sides, in which the heat loaded element is put. The plates have a current conducting coating. The radiator device has a ventilator, fitted such that, air streams pass through parallel thermal plates. Besides that, the radiator device is in electrical contact with the contact area of a printed circuit board, forming a single earthing contour.

EFFECT: design of a highly efficient heat transfer radiator and protection from electromagnetic interferences.
