A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cast part including a cross-sectional circular area spanning at least a portion of each of four internal passages includes a ratio of interior empty space to inner wall space that improves heat transfer.

Cast plate heat exchanger and method of making using directional solidification

A casting core assembly is disclosed herein. The casting core assembly comprises a casting core and a bumper assembly. The bumper assembly is disposed on an outer surface of the casting core. The bumper assembly comprises a receptacle and a metal apparatus. The metal apparatus may be a pin, a sphere, or the like.

Integral core bumpers

A casting shell has: a part cavity shaped for casting the part; a starter/selector cavity below and connected to the part cavity; a connector cavity between the starter/selector cavity and the part cavity; and a support cavity. The support cavity has: a post section; a first linking section linking the post section to the starter section of the starter/selector cavity; and a second linking section linking the post section to the connector cavity, the second linking section having a portion descending from the post section toward the connector cavity.

Casting shell with grain selector support

A casting method includes forming a seed. The seed has a first end and a second end and an inner diameter (ID) surface and an outer diameter (OD) surface. The seed second end is placed in contact or spaced facing relation with a chill plate. The first end is contacted with molten material. The molten material is cooled and solidified so that a crystalline structure of the seed propagates into the solidifying material. At least a portion of the seed contacted with the molten material has a solidus higher than a solidus of at least an initial pour portion of the molten material.

Arcuate seed casting method

A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cooling fin includes a ratio of fin height to an average fin thickness that is greater than 2.0 and no more than 18.0. A method is also disclosed.

A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled where each hot core plate is directly interlocked to at least one cold core plate. A wax pattern is formed with the core assembly with an external shell formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material. Once the molten material has solidified, the external shell and the core are removed.

Stackable core system for producing cast plate heat exchanger

A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled wherein each hot core plate is directly interlocked to the at least one cold core plate. A wax pattern is formed with the core assembly. An external shell is formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material and cures the molten material. The external shell is removed. The core assembly is removed. A core assembly for a cast heat exchanger is also disclosed.

A heat exchanger is disclosed and includes a plate portion including a plurality of internal passages extending between an inlet and an outlet and at least one means for providing fluid communication between at least two of the plurality of internal passages.

Mixing between flow channels of cast plate heat exchanger

A method comprises: providing a spiral metallic workpiece having a cast structure associated with such spiral; and at least partially flattening the workpiece.

Cast components and manufacture and use methods

A die casting system includes a die including at least one die component that defines a die cavity, a spar received within a portion of said die cavity, a shot tube in fluid communication with the die cavity, and a shot tube plunger moveable within the shot tube to communicate a molten metal into the die cavity to cast a hybrid component. The spar establishes an internal structure of the hybrid component, and one of the internal structures and an outer structure of said hybrid component is an equiaxed structure.

Method and system for die casting a hybrid component

A method casts a plurality of alloy parts in a mold () having a plurality of part-forming cavities (). The method comprises pouring a first alloy into the mold causing: the first alloy to branch into respective flows along respective first flowpaths () to the respective cavities; and a surface of the first alloy in the part-forming cavities to equilibrate. The method further comprises pouring a second alloy into the mold causing: the second alloy to branch into respective flows along respective second flowpaths () to the respective cavities.

Method and apparatus for manufacturing a multi-alloy cast structure

A method for casting comprising: providing a seed, the seed characterized by: an arcuate form and a crystalline orientation progressively varying along an arc of the form; providing molten material; and cooling and solidifying the molten material so that a crystalline structure of the seed propagates into the solidifying material.
