Flat water cooling block

Abstract

A flat convective cooling cell is providing the vortical boiling regime of flow of coolant inside it what allows exploiting important advantages of the vortical boiling phenomenon: highest coefficient of heat transfer at very small increasing of hydro-resistance, unchangeable or even increasing performance (thermo-resistance) at increasing of the coolant's discharge, and anti-adhesive action of stream inside cooling cell. The cell comprises a heat intake box and coolant entrance and exit channels with couplers on their ends. The triangular lattice of hemi-spherical dimples on the top and bottom sides of cell provides generation of coherent system of vortical tubes that effectively sucks heat from the dimple into the core of the coolant's stream. Essentially, the cell allows many technologies of manufacturing: milling, stamping, melting, and/or their combinations.

1 . A convective cooling cell, that being in good thermo-mechanical contact with a heated surface, providing an intake of heat from this surface and transport of it into an appropriate refrigerator due to fluid coolant that is passing through said cell, comprising:
 a heat intake box, the top and bottom inner surfaces, both or one of which is shaped in the form of triangular lattice of sectored spherical dimples that do not allow a potential streamlining by the coolant at any its velocity, so that the vortical boiling regime of streamlining has to develop;   an inlet and outlet coolant transporting channels, the normal cross-section of which is kept with a constant or even narrowing total square area;   
       and
 couplers on the ends of each channel to connect said cell with the external coolant transporting communications; 
 
       wherein:
 inlet channel is shaped in such a way, which provides non-broken stream of coolant on the entrance of the heat intake box; 
 the coolant transporting channel into the heat intake box is organized in such a way that provides a straight-forward core flow of coolant from entrance to exit of said box; 
 the triangular lattice of sectored spherical dimples on the top and bottom inner surfaces of the heat intake box is oriented in such a way that the distance between any two neighbor dimples, that are laying along the same straight streamline of coolant, is square root of 3 times longer than the parameter of said lattice; 
 the triangular lattice of sectored spherical dimples on the top and bottom inner surfaces of the heat intake box is organized in such a way that provides the regime of vortical boiling flow of coolant into said box; 
 dimples in the triangular lattice of sectored spherical dimples on the top and bottom inner surfaces of the heat intake box are grinded along 30 degrees in both side in respect to the direction of stream of coolant into the heat intake box, in order to provide saddle-like path between dimples along grinded directions; 
 and all constructive elements of described device are placed in flat lain that all device appears as a flat construction, thickness of which everywhere does not exceeds the thickness of its central part—heat intake box. 
 
     
     
         2 . The apparatus of  claim 1 , further comprising two parts—an upper part and a lower part that, being soldered or welded one on top of other, accomplish said convective cooling cell.
