HEAT EXCHANGE ELEMENT WITH SPATIAL LATTICE ORDERED STRUCTURE AND CENTRAL BODY Russian patent published in 2025 - IPC H01L23/367 H05K7/20 

FIELD: heat exchange.

SUBSTANCE: proposed invention relates to heat exchange devices, for example, radiators containing spatial lattice ordered structure. Said devices have a universal nature, they can be used, for example, for cooling microprocessors and controllers, power transistors, elements of power plants, etc. Heat exchange element with spatial lattice ordered structure and central body, made by selective laser melting from metal, comprises housing surface with possibility of contact with heat generating device, cooling part containing spatial lattice ordered structure formed by layers of lattice elements arranged one above the other and connected to each other at connection points. In addition, it contains a central solid body in the form of a cone with a concave side surface, which is connected to the body surface by its base and made so that its upper part and the base do not extend beyond the boundary of the spatial lattice ordered structure of the heat exchange element. Cooling part is made around the central solid body and is connected to it and to the body surface; at that, the number of layers of lattice elements is equal to 2-100, and the size of one lattice element is 0.1-100 mm.

EFFECT: higher efficiency of heat release, smoother and more directed movement of air flow inside the heat exchange element, as well as more uniform distribution of heat over the entire area of the heat exchange element.
