Combining with entr.nsy theor., constr.cta. designs of the X-sha.ed va.cula.0}networ.s(XSVNs) a.0} implemented with fixed tota. tube volumes of the XSVNs. The entr.nsy dissipa.ion r.tes(EDr.) of the XSVNs a.0} minimized, a.d the optima. constr.cts of the XSVNs a.0} der.ved. Compa.0}son of the optima. constr.cts of the XSVNs with two optimiza.ion objectives(EDr.minimiza.ion a.d entr.py gener.tion r.te(EGr. minimiza.ion) is conducted. It is found tha. when the dimensionless ma.s flow r.te(DMFr. is sma.l, the optima. dia.eter.r.tio of the elementa. XSVN der.ved by EDr.minimiza.ion is differ.nt fr.m tha. der.ved by EGr.minimiza.ion. For.the multilevel XSVN, when the DMFr.is 100, compa.0}d the XSVN with the cor.esponding H-sha.ed va.cula.0}networ.(HSVN), the dimensionless EDr. of the elementa., second a.d four.h or.er.XSVNs a.0} r.duced by 26.39%, 15.34% a.d 9.81%, r.spectively. Compa.0}d with the entr.nsy dissipa.ion number.EDN) of the second or.er.XSVN befor. a.gle optimiza.ion, the EDN a.ter.optimiza.ion is r.duced by 26.15%, which illustr.tes tha. it is significa.t to conduct a.gle optimiza.ion of the XSVN. Entr.nsy theor. is a.plied into the constr.cta. design of the va.cula.ur. with hea. tr.nsfer.a.d fluid flow in this pa.er. which pr.vides new dir.ctions for.the va.cula.ur. designs.
