The utility model relates to a domestic electrical appliance, in particular to a multiple combined semiconductor cold-warm generator used for a cold-warm mattress, having the silent and quickly cold-warm generating functions. The utility model is characterized in that on the structure basis of the original cold-warm generator, a plurality of semiconductor refrigerating sheets (4) are arranged and installed on a cold-warm exchanging flat plate conductor (1) at a multiple combined rule and are tightly contacted with a radiator (5) which adopts a heat tube radiator and has a circulating pipeline in which a low-boiling point liquid working medium is arranged, the structure of the cold-warm exchanging flat plate conductor (1) is that the cavity of the inner part is provided with a sealed labyrinth type circuitous channel and is communicated with an inlet and an outlet (2), a fan (7) adopts the low speed, the rotation speed of the fan is less than 1000 rotation / minutes, and the noise of the fan is less than 40 decibels. The utility model has the effects of large cold-warm generating quantity and quick cold-warm generating speed, high radiating efficiency, good conducting performance, low noise and silence.
