1. A cooling system, comprising:
- a cooling device including a plurality of cooling elements each including a thermoelectric cooler and an internal fluid chamber configured to hold liquid in thermal communication with the thermoelectric cooler, wherein the plurality of cooling elements includesat least one central cooling element, andtwo end cooling elements, wherein each end cooling element is hingedly coupled to the at least one central cooling element;
a cooling unit configured to cool liquid; and
a supply line and a return line between the cooling unit and the cooling device such that liquid cooled by the cooling unit flows through each of the cooling elements, the supply line, and the return line while the cooling device cools subcutaneous lipid-rich cells of a subject to a low temperature for selectively disrupting the subcutaneous lipid-rich cells of the subject.

Abstract
A cooling device for removing heat from subcutaneous lipid-rich cells of a subject having skin is provided. The cooling device includes a plurality of cooling elements movable relative to each other to conform to the contour'"'"'s of the subject'"'"'s skin. The cooling elements have a plurality of controllable thermoelectric coolers. The cooling elements can be controlled to provide a time-varying cooling profile in a predetermined sequence, can be controlled to provide a spatial cooling profile in a selected pattern, or can be adjusted to maintain constant process parameters, or can be controlled to provide a combination thereof.
