FIELD: refrigerating machines. ^ SUBSTANCE: refrigerator comprises basic printed circuit board provided with an assembly of integrated circuits, heat exchanging plate arranged in the vicinity of the surface of the basic printed circuit board and adopted for absorbing heat, which is generated by the integrated circuits, pipe provided with the inlet and outlet branch pipes, which are in communication with the inner space of the freezing chamber which is in a contact with a part of the bottom of the basic printed circuit board for permitting air to flow over it from the freezing chamber to the heat exchanging plate, temperature sensor mounted on the surface of the basic printed circuit board, and controllable valves mounted in the inlet and outlet branch pipes. The valves open the passage in pipes for flowing cold air from the freezing chamber, when the temperature measured by the sensor exceeds a given value, and close the passage in pipe, when the temperature underlies a given value. ^ EFFECT: reduced sizes and power consumption. ^ 5 cl, 5 dwg |
