A helmet was designed in this study using flexible thermoelectric modules for locally controlled cooling and heating of brain. Controller design of the cooler helmet was carried out under fuzzy logic control according to the data obtained in the previous tests on flexible thermoelectric modules used in the helmet. Test assembly was prepared for load and no load tests of the helmet in laboratory environment. A balloon with 6 liters of water was used to test the load operation of the helmet. These parameters were evaluated and discussed with respect to brain hypothermia. Power of the brain cooling system is 1.2 kW, cooling capacity is 140 w, coefficient of performance (COP) 0.6, load heating speed is 0.5 °C/minute and load cooling speed is 0.4 °C/minute. Magnetic field around the helmet was measured as 11 µT. Tests on the model showed that the helmet is one of the most important alternatives to cooling the brain locally, controlled heating when necessary as well as keeping it at the same temperature for long periods of time.
