Abstract
An undulating prismoid module made of relatively rigid material. The prismoids may have bases of any number of sides, and preferably a plane passing through the centers of the prismoid bases in any row of prismoid bases is nonparallel to the sides of the module. The modules may be stacked and fluid inlets and outlets provided in the void volume between modules so that the modules may be used as a heat exchanger, an extraction tower, absorption towers, distillation towers, an adsorption tower, chemical or bilogical reactors, and water cooling towers. The modules are disposed in repeating patterns of four in the stack, each module in the stack being rotated 180.degree. about a first or second horizontal axis with respect to the previous model.
Claims7
A stack of substantially identical undulating prismoid modules, each undulating prismoid module having a polygon shape in plan, and made of relatively rigid material;
- the stack having at least first and second modules, and means for providing confined flow of fluid between the modules, including inlet and outlet means;
- wherein the improvement comprises
- for each module a plane passing through the centers of the prismoid bases in any row of prismoid bases being nonparallel to the sides of the module;
- and
- the first module in the stack having a first orientation, and being disposed in a horizontal plane, and the second module having a second orientation which is said first orientation rotated 180.degree. about a first horizontal axis, so that some, but not all, prismoid projecting bases of each module abut those of the other module.
A stack of substantially identical undulating prismoid modules, each module being quadrate and made of relatively rigid material;
- the stack having at least first and second modules, and means for confining a flow of fluid between the modules, including inlet and outlet means, wherein the improvement comprises:
- each module formed so that the prismoids forming the module have quadrate bases, and wherein a plane passing through the diagonals of a plurality of prismoids of the module makes a first actue angle of greater than 45.degree. with a module edge that it intersects, or a second acute angle which is the complement of the first acute angle;
- and
- the first module in the stack having a first orientation, and being disposed in a horizontal plane, and the second module having a second orientation which is said first orientation rotated 180.degree. about a first horizontal axis, so that some, but not all, prismoid projecting bases of each module abut those of the other module.
A stack of substantially identical undulating prismoid modules, each module being quadrate and made of relatively rigid material, and at least four modules being provided in the stack;
- and including means for confining fluid flow between modules in the stack including inlet and outlet means:
- wherein the improvement comprises
- each module being constructed so that a plane passing through the diagonals of a plurality of prismoids of the module makes a first acute angle of greater than 45.degree. with the module edge that it intersects, or a second acute angle which is the complement of the first acute angle;
- and
- wherein the first module in the stack has a first orientation, and is disposed in a horizontal plane;
- and the second module in the stack has a second orientation which is said first orientation rotated 180.degree. about a first horizontal axis;
- and the third module in the stack has a third orientation which is said second orientation rotated 180.degree. about a second horizontal axis perpendicular to said first horizontal axis;
- and the fourth module in the stack has a fourth orientation which is said third orientation rotated 180.degree. about said first horizontal axis;
- and wherein subsequent modules in the stack repeat said first, second, third, and fourth orientations in order;
- so that some, but not all, prismoid projecting bases of each module abut those of the modules adjacent thereto.
A stack of of substantially identical undulating prismoid modules, each module having a polygon shape in plan and made of relatively rigid material;
- at least four modules being provided in the stack;
- and means for confining the flow of fluid between the modules in the stack, including inlet and outlet means, wherein the improvement comprises
- each of said undulating prismoid modules being polygon shaped in plan, and a plane passing through the centers of the prismoid bases in any row of prismoid bases being nonparallel to the sides of the modules;
- and
- wherein the first module in the stack has a first orientation, and is disposed in a horizontal plane;
- and the second module in the stack has a second orientation which is said first orientation rotated 180.degree. about a first horizontal axis;
- and the third module in the stack has a third orientation which is said second orientation rotated 180.degree. about a second horizontal axis perpendicular to said first horizontal axis;
- and the fourth module in the stack has a fourth orientation which is said third orientation rotated 180.degree. about said first horizontal axis;
- and wherein subsequent modules in the stack repeat said first, second, third, and fourth orientations in order;
- so that some, but not all, prismoid projecting bases of each module abut those of the modules adjacent thereto.
