Abstract
Heat exchangers machined form a thermally oriented block of composite material is provided. First and second arrays of fins can be machined into opposite sides of the block. Composite plates can be disposed over the machined fins to form passageways. The composite plates and fins are specially constructed to maximize heat transfer between adjacent passageways formed by the plates and the fluids flowing in these passageways.
Claims15
A heat exchanger comprising:
- a block of anisotropic fibrous carbon composite material specially aligned to provide a structure having a predominant axis of thermal conductivity specially oriented in a first direction whereby significant heat is transferred along the predominant axis than is transferred along any other orthogonal axis;
- first and second arrays of substantially parallel planar fins extending in said first direction and machined along the predominant axis on opposite sides of the block respectively;
- said fins having tips positioned at their ends projecting in said first direction and
- a first composite plate bonded to the tips of the array of composite fins to form a passageway.
