Abstract
A jet impingement cooling device may include a jet structure and a target layer. The jet structure may include at least one fluid jet operable to produce an impingement jet of cooling fluid. The target layer may further include a heat receiving surface configured to be coupled to a heat generating device and a jet impingement target surface. The jet impingement target surface may further include at least one target structure having a wavy-fin topology with a fin peak, wherein the fluid jet and the target structure are arranged such that the fin peak of the target structure is aligned with a centerline of the impingement jet of cooling fluid during operation of the jet impingement cooling device.
Claims20
A jet impingement cooling device comprising:
- a jet structure comprising at least one fluid jet for producing an impingement jet of cooling fluid;
- and
- a target layer comprising a heat receiving surface configured to be coupled to a heat generating device, and a jet impingement target surface, the jet impingement target surface further comprising at least one target structure comprising a wavy-fin topology having a fin peak, wherein the fluid jet and the target structure are arranged such that the fin peak of the target structure is aligned with a centerline of the impingement jet of cooling fluid during operation of the jet impingement cooling device.
A power module comprising:
- a semiconductor module;
- and
- a jet impingement cooling device comprising:
- a jet structure comprising at least one fluid jet for producing an impingement jet of cooling fluid;
- a target layer further comprising:
- a heat receiving surface coupled to a first surface of the semiconductor module;
- and
- a jet impingement target surface, the jet impingement target surface comprising at least one target structure further comprising a wavy-fin topology having a fin peak, wherein the fluid jet and the target structure are arranged such that the fin peak of the target structure is aligned with a centerline of the impingement jet of cooling fluid during operation of the jet impingement cooling device;
- and
- a cooling fluid reservoir positioned between the jet structure and the jet impingement target surface, wherein the cooling fluid reservoir receives cooling fluid from the fluid jet and comprises an outlet for providing a cooling fluid exit flow.
A method of cooling a heat generating device comprising:
- providing a target layer comprising a heat receiving surface coupled to the heat generating device, and a jet impingement target surface, wherein the jet impingement target surface comprises an array of target structures, each target structure comprising a wavy-fin topology having a fin peak;
- providing an array of fluid jets;
- and
- directing impingement jets of cooling fluid from the array of fluid jets toward the array of target structures such that each impingement jet of cooling fluid directly impinges the fin peak of each target structure, wherein heat generated by the heat generating device is transferred to the cooling fluid to create a substantially uniform temperature distribution across the jet impingement target surface.
