Abstract
The invention relates to a multistage semiconductor thermoelectric cooling assembly which comprises a ceramic substrate, current guide pieces, N type semiconductors, P type semiconductors and current guide strips. The multistage semiconductor thermoelectric cooling assembly is formed from a first stage of semiconductor thermoelectric cooling assembly to an Nth stage of semiconductor thermoelectric cooling assembly in a stacking manner, and ceramic substrate bodies are fixedly bonded between layers. The sizes of the ceramic substrate are gradually reduced from the lower layer to the upper layer to be in a pagoda shape. A double-side metallization design method is adopted in the ceramic substrate bodies between all the stages. The current guide pieces are fixedly bonded to the ceramic substrate reasonably and orderly. The N type semiconductors and the P type semiconductors are fixedly bonded to the current guide pieces respectively. The N type semiconductors and the P type semiconductors in each layer are sequentially connected in series through the current guide pieces. The semiconductors between the layers are connected through the current guide strips. The N type semiconductors and the P type semiconductors in the whole assembly are sequentially connected in series at intervals. The number of couple pairs of the last stage of the multistage semiconductor thermoelectric cooling assembly is not larger than 60% of that of couple pairs of the next stage of the multistage semiconductor thermoelectric cooling assembly. According to the scheme, a large temperature difference can be provided.
