Various embodiments of the present invention relate to an electronic device including a stacked circuit board. The electronic device comprises: a first circuit board; a second circuit board; one or more circuit elements disposed on the second circuit board; and a connecting member disposed between the first circuit board and the second circuit board facing the first circuit board to form an internal space surrounding at least some of the one or more circuit elements, and to electrically connect the first and second circuit boards, wherein the internal space may be filled with a phase change material (PCM) that absorbs heat generated by the at least some circuit elements to change the state of the material. Various other embodiments of the present invention may be additionally provided.

Electronic device filled with phase change material between plurality of circuit boards connected by connecting members

A method of an electronic device are provided in which current consumption for one or more components of the electronic device is compared with a predetermined current. A first surface temperature of the electronic device is determined based on the comparison and power consumption of the one or more components. A location is detected where heat corresponding to the first surface temperature is generated. A second surface temperature of the electronic device is obtained based on power consumption of a component disposed in the electronic device corresponding to the location where the heat is generated. A target temperature is set based on the obtained second surface temperature. The component is controlled to reduce the power consumption of the component based on the target temperature.
