DEVICE FOR COOLING RADIO-ELECTRONIC DEVICE Russian patent published in 2009 - IPC H05K7/20 

FIELD: electrical engineering.

SUBSTANCE: present invention relates to electrical engineering, to cooling components of a radio-electronic device. The said cooling device has a cooling system, consisting of an evaporator, filled with a heat carrier, and a condenser, joined to each other. The evaporator is attached to the cooled component of the radio-electronic device. The evaporator and the condenser are made in form of containers. The surface area of the evaporator is larger than the surface area of the cooled component. The surface of the evaporator except the walls, which are in contact with the cooled component, is coated with heat insulating material. The evaporator and the condenser are also made in form of flat containers with wide and narrow walls and joined together by two flexible metal pipes. One of the pipes is a steam pipe, and the other is a condensate pipe. The volume of the heat carrier, filled in the evaporator, is defined by the expression V_h ⁼V₁+V₂+V₃, where V₁=(0.1-0.15)V_e - is volume of heat carrier in the evaporator during operation, V_e is the inner volume of the cavity of the evaporator, V₂ is the volume of heat carrier, forming a film on the inner surface of the condenser and condensate pipe, V₃ - is the volume of heat carrier, converted to vapour phase during operation. The evaporator is attached to the cooled component without a gap using an adhesive highly heat-conductive material.

EFFECT: increased efficiency and reliability of cooling radio-electronic components, as well as increased safety of operation and service life of the device.
