Patent ID: 8496048

Claim:
A convective cooling cell, that being in good contact with a heated surface, providing an intake of heat from this surface and transport of it into an appropriate refrigerator by the fluid coolant that is passing through said cell, comprising: a heat intake box, the top and bottom inner surfaces of which are shaped in the form of triangular lattice of segmental spherical dimples; an inlet (diffuser) and outlet (confuser) coolant transporting channel; wherein: inlet channel is shaped as a diffuser, which provides a laminar uniform non-broken stream of coolant all over the entrance of the heat intake box; the coolant transporting channel into the heat intake box provides a straight-forward flow of coolant's core everywhere into said heat intake box from the entrance to the exit of said box; the triangular lattice of segmental spherical dimples on the top and bottom inner surfaces of the heat intake box is oriented in respect to the direction of the coolant's core flow so, that the distance between any two neighbor dimples, that are laying along the same straight streamline of coolant's core flow, is square root of 3 times longer than the parameter of said lattice; the triangular lattices of segmental spherical dimples on the top and bottom inner surfaces of the heat intake box are oriented in respect to each other so, that dimple of the top inner surface of the heat intake box is suited over a corresponding dimple on the bottom inner surface of said box; outlet channel is shaped as a confuser, which provides collection of a laminar non-broken stream of coolant all over the entrance of outlet channel and till its exit; dimples in the triangular lattice of segmental spherical dimples on the top and bottom inner surfaces of the heat intake box are grinded with a sandpaper along direction under 30 degrees in respect to the direction of stream of coolant's core into the heat intake box, in order to provide saddle-like path between dimples along direction of said grinding.
