Abstract:
A thermoelectric module comprising:a case, P-type and N-type semiconductor tips having an exoergic side and an endoergic side, said P-type and N-type semiconductor tips being positioned in said case, an insulating base plate for the exoergic side positioned in said case, an insulating base plate for the endoergic side positioned in said case, a first soldering layer which joins the insulating base plate for the exoergic side to said case via first soldering material, and second soldering layers which respectively join the P-type and N-type semiconductor tips to the insulating base plate for the exoergic side and the insulating base plate for the endoergic side using a second soldering material, wherein a melting point temperature of first soldering material for the first soldering layer is higher than a melting point temperature of the second material for the second soldering layers.
