  The global solutions with large initial data for the isothermal compressible
fluid models of Korteweg type has been studied by many authors in recent years.
However, little is known of global large solutions to the nonisothermal
compressible fluid models of Korteweg type up to now. This paper is devoted to
this problem, and we are concerned with the global existence of smooth and
non-vacuum solutions with large initial data to the Cauchy problem of the
one-dimensional nonisothermal compressible fluid models of Korteweg type. The
case when the viscosity coefficient $\mu(\rho)=\rho^\alpha$, the capillarity
coefficient $\kappa(\rho)=\rho^\beta$, and the heat-conductivity coefficient
$\tilde{\alpha}(\theta)=\theta^\lambda$ for some parameters
$\alpha,\beta,\lambda\in \mathbb{R}$ is considered. Under some assumptions on
$\alpha,\beta$ and $\lambda$, we prove the global existence and time-asymptotic
behavior of large solutions around constant states. The proofs are given by the
elementary energy method combined with the technique developed by Y. Kanel'
\cite{Y. Kanel} and the maximum principle.
