    摘要： A casting includes a heat transfer surface having a plurality of cavities. The plurality of cavities include a density of at least about 25 cavities per square centimeter to about 1,100 cavities per square centimeter resulting in increased surface area and therefore enhanced heat transfer capability. Also disclosed is a mold for forming a pattern for molding the casting. The mold includes a surface defining a portion of a chamber to which are attached a plurality of particles having an average particle size in a range of about 300 microns to about 2,000 microns.

    摘要翻译： 铸件包括具有多个空腔的传热表面。 多个空腔包括每平方厘米至少约25个腔体至每平方厘米约1,100个空腔的密度，导致增加的表面积并因此提高传热能力。 还公开了一种用于形成用于模制铸件的图案的模具。 模具包括限定室的一部分的表面，其中连接有平均粒度在约300微米至约2,000微米范围内的多个颗粒。

    摘要： A casting includes a heat tranfer surface having a pluality of cavities. The plurality of cavities includes a density of at least about 25 cavities per square centimeter to about 1,100 cavities per square centimeter resulting in increased surface area and therefore enhanced heat transfer capability. Also disclosed is a mold for forming a pattern for molding the casting. The mold includes a surface defining a portion of a chamber to which are attached a plurality of particles having an average particle size in a range of about 300 microns to about 2,000 microns.
