1. A method of treating a stroke patient suffering from stroke by cooling the stroke patient's head to alleviate damage caused by said stroke, the method comprising: providing a cooling device comprising a thermal exchange cap to be arranged on the stroke patient's head, an adjustable heat exchange surface and at least one flow passage system forming the heat exchange surface, wherein the at least one flow passage system comprises at least one inlet and at least one outlet forming a single flow path in a front section of the cooling device between one inlet and one outlet, and wherein the thermal exchange cap comprises an opening constructed to receive a syringe for injecting heat conducting material; applying the heat exchange surface directly against the stroke patient's head; injecting a heat conducting material through the opening into the cap to adjust the fit of the cap, wherein the heat conducting material is selected from the group consisting of a gel, a hydrogel, a liquid, and a paste; and flowing a cooling liquid in the at least one flow passage system, wherein the heat exchange surface separates the stroke patient's head from the cooling liquid so that the cooling liquid does not contact the stroke patient's head during the step of flowing the cooling liquid, and wherein the single flow path comprises a plurality of loops arranged to flow cooling liquid across the stroke patient's head in the front section of the cooling device.
