Abstract
A cooling device for cooling a component comprising a heat sink, a housing having an inner chamber, wherein a volume-changing device is formed to withdraw a fluid into the chamber and to expel the fluid from the chamber, the withdrawal causing a first flow and the expulsion causing cortices which form a second flow. A preheating device is also provided and is configured to convey the first flow and the second flow, and to increase the temperature of the first fluid quantity entrained by the first flow during the withdrawal from an initial temperature to a first temperature, and to increase the second fluid quantity entrained by the second flow, from the first temperature to a second temperature.
Claims25
A cooling device for cooling a component, comprising:
- a heat sink,
- a housing having an inner chamber, a volume-changing device formed to withdraw a fluid into the chamber and to expel the fluid from the chamber, the withdrawal causing a first flow and the expulsion causing vortices which form a second flow;
- and
- a preheating device configured to convey the first and second flows, to increase a temperature of a first quantity of fluid entrained by the first flow during the withdrawal from an initial temperature to a first temperature, and to increase the temperature of a second quantity of fluid entrained by the second flow, from the first temperature to a second temperature.
A method for operating a cooling device in which a volume-changing device is movably arranged in a housing having an inner chamber, comprising:
- moving the volume-charging device in the housing so that a fluid is withdrawn into the chamber in a first movement direction to cause a first flow of the fluid and so that the fluid is expelled from the chamber in a second movement direction to form vortices which cause a second flow;
- conveying the first flow through a preheating device, a temperature of a first quantity of fluid entrained by the first flow being increased from an initial temperature to a first temperature by the preheating device during the withdrawal;
- and
- conveying the second flow through the preheating device, a temperature of a second quantity of fluid entrained by the second flow being increased from the first temperature to a second temperature by the preheating device during the expulsion.
