Abstract
Provided is a heatsink, including a cooling zone to contact an object to be frozen and having microchannels formed therein to define a plurality of fluid pathways, an inlet through which a working fluid enters, a distributor, interposed between the inlet and the cooling zone, to uniformly distribute the working fluid introduced through the inlet to the microchannels, an outlet through which the working fluid, passing through the cooling zone, exits, and a collector, interposed between the cooling zone and the outlet, to collect the working fluid passing through the microchannels.
Claims20
A heatsink, comprising:
- a cooling zone to contact an object to be frozen and having microchannels formed therein to define a plurality of fluid pathways;
- an inlet through which a working fluid enters;
- a distributor, interposed between the inlet and the cooling zone, to uniformly distribute the working fluid introduced through the inlet to the microchannels;
- an outlet through which the working fluid, passing through the cooling zone, exits;
- and
- a collector, interposed between the cooling zone and the outlet, to collect the working fluid passing through the microchannels;
- wherein a width of the distributor gradually increases from an end of the inlet to a beginning of the cooling zone, and a width of the collector gradually decreases from an end of the cooling zone to a beginning of the outlet, and
- wherein a length of the distributor is given by the relationship,

- where L denotes the length of the distributor, De denotes a maximum width of the distributor, D denotes a minimum width of the distributor, and θ denotes an inclination angle of the distributor relative to longitudinal lengths of the inlet and the outlet.
A heatsink to cool a surface of an object to be frozen, comprising:
- a cooling zone to contact the object to be frozen, the cooling zone having a plurality of fluid pathways formed therein to substantially cover the object to be frozen;
- a distributor to distribute a fluid to the microchannels with a uniform pressure distribution to remove heat from the surface of the object to be frozen;
- and
- a collector to collect the fluid having passed through the microchannels without a substantial change in the pressure distribution thereof;
- and
- wherein a width of the distributor gradually increases from an end of the inlet to a beginning of the cooling zone, and a width of the collector gradually decreases from an end of the cooling zone to a beginning of the outlet, and
- wherein a length of the distributor is given by the relationship,
