Abstract

The present invention relates to a device, which is composed of one or more parallel or quasi-parallel installed fluid piping by series or parallel connection, each piping is specifically distributed by one or more double-scroll arrangement for transmitting thermal conductive fluid, and the double-scroll fluid piping constitutes fluid flow uniformly distributed by temperature difference.
