Abstract
A heat exchanger includes an outer shell enclosing an interior space. An inlet extends through the outer shell and is in fluidic communication with the interior space. An outlet extends through the outer shell and is in fluidic communication with the interior space. At least one phase change element is inside the interior space and includes a core comprising a phase change material.
Claims16
A heat exchanger comprising:
- an outer shell enclosing an interior space;
- an inlet extending through the outer shell and in fluidic communication with the interior space;
- an outlet extending through the outer shell and in fluidic communication with the interior space;
- and
- at least one phase change element inside the interior space, wherein the at least one phase change element comprises:
- a core comprising a phase change material and wherein the phase change material is tubular in shape;
- and
- a membrane that is tubular in shape and completely covering a surface area of the phase change material, and comprising an elastic material that is impermeable to the phase change material and a coolant fluid in the heat exchanger.
5 more elements
A heat exchanger comprising:
- a plurality of phase change elements, wherein each phase change element of the plurality of phase change elements comprises:
- a core comprising a phase change material;
- an outer housing surrounding the plurality of phase change elements and forming flow channels between the outer housing and the plurality of phase change elements, wherein the outer housing extends from a first end to a second end;
- an inlet formed in the outer housing and in fluidic communication with the flow channels;
- and
- an outlet formed in the outer housing and in fluidic communication with the flow channels, and
- wherein the plurality of phase change elements comprises:
- a plurality of spherical phase change elements;
- and
- a plurality of elongated phase change elements, wherein the plurality of elongated phase change elements extends between the first end and the second end of the outer housing, extends over the inlet and over the outlet within the outer housing, and holds the plurality of spherical phase change elements in place and prevents the plurality of spherical phase change elements from moving into the outlet or the inlet.
