Techniques provide improved thermal interface material application in an assembly associated with an integrated circuit package. For example, an apparatus comprises an integrated circuit module, a printed circuit board, and a heat transfer device. The integrated circuit module is mounted on a first surface of the printed circuit board. The printed circuit board has at least one thermal interface material application via formed therein in alignment with the integrated circuit module. The heat transfer device is mounted on a second surface of the printed circuit board and is thermally coupled to the integrated circuit module. The second surface of the printed circuit board is opposite to the first surface of the printed circuit board.

A heat dissipation module includes an airflow generation device that generates airflow into an air channel in which a fin module is received and fixed. The fin module includes a plurality of fin plates substantially parallel to and spaced from each other to define air passages extending from an inlet to an outlet of the air channel. Each fin plate has a trailing section extending to the outlet and forming at least one inclined guide tab and an opening defined in the fin plate immediately close to the guide tab for switching at least a portion of the air between adjacent air passages on opposite sides of the fin plate. This increases the length of the path that the air flows through the air channel and thus raises the amount of heat exchanged between the fin plates and the air thereby enhancing efficiency of heat removal.

A cooling system and method that significantly improves spray evaporative cooling by using a mixture of cooling fluids having different boiling points. The cooling fluid mixture is sprayed onto a surface to be cooled. Efficient cooling with reduced cooling fluid volume is provided by both evaporation of the more volatile component of the mixture as well as heating of the less volatile component which remains in contact with the surface being cooled. More uniform temperatures across the surface being cooled and a reduced risk of potentially damaging critical heat flux is achieved.

A heat-removing device for a vehicle including: an interior part having a plate portion exposed to direct sunlight including a baseboard formed of a resin or a composite material containing a resin and a skin material which covers an outer surface of the baseboard; a heat conducting plate for collecting heat from the skin material, provided on an inner side of the skin material of the plate portion and inside of an inner surface of the baseboard in a direction of a thickness of the baseboard; and a heat pipe provided on an inner side of the inner surface of the baseboard and connected in heat-conductive relationship to the heat conducting plate, which transfers heat collected by the heat conducting plate to a heat releasing device.

The invention relates to the field of atomic energy, and specifically to systems which provide for the safety of nuclear power plants, and may be used in the event of serious accidents leading to the destruction of a reactor housing and of the hermetic containment structure of a nuclear power plant. A system for confining and cooling melt contains: a guide plate in the form of a funnel, installed under the bottom of a reactor housing; a cantilever truss, installed under the guide plate so that the plate rests on same; a melt catcher, installed under the cantilever truss and provided with a cooling casing in the form of a multi-layered vessel for protecting an outer heat-exchange wall against dynamic, thermal and chemical influences; and a filler for diluting the melt, located in said multi-layered vessel. Said multi-layered vessel contains a metal inner layer and a metal outer layer, between which is provided an intermediate layer in the form of a non-metal filler; wherein, reinforcing ribs are provided between the inner and outer layers, said ribs being installed with an azimuthal spacing (Spitch) which satisfies the condition: d<ext> / 15<(s<pitch>)<d<ext> / 5, where d<ext> is the outer diameter of the vessel. The technical result consists in increasing the effectiveness of removing heat from a melt and in increasing design reliability.

The invention relates to nuclear power industry, namely to systems providing safety of nuclear power plants (NPP), and can be used during severe accidents leading to reactor vessel and NPP containment failure. The melt cooling and confinement system includes a cone-shaped guide plate installed under the reactor vessel bottom, cantilever girder installed under the guide plate and supporting the same, core catcher installed under the cantilever girder and equipped with cooled cladding in form of a multi-layer vessel for protection of the external heat-exchange wall from dynamic, thermal and chemical impacts, and filler material for melt dilution inside the multi-layer vessel. The said multi-layer vessel has external and internal metal walls with a filler that is highly heat-conductive in relation to wall material in between, where filler material thickness hfil meets the following criterion: 1.2hext< hfil <2.4hext, where hext is vessel external wall thickness. The technical result of the invention is the increased efficiency of heat removal from the melt and improved structural reliability
