Heating device

Abstract

The chamber (23) containing the viscous fluid being sheared, is constructed directly in a cavity of the impeller rotor (7)

Description

technical field [0001] The invention relates to a heating device for a temperature-controlled fluid conveyed by means of a conveying rotor. Within the scope of the present invention, such fluids may generally be of a liquid form, and optionally also of a gaseous type. Fields of application of such heaters can also be used for particularly different purposes, like room temperature control, heating of cooling liquids for internal combustion engines, etc. [0002] The delivery rotor is mounted on a shaft which is rotated by a drive device, wherein the heating device generates heat for release to the temperature control fluid by shear forces in the chamber containing the viscous liquid by means of the rotating shear structure. Background technique [0003] Heating devices that work with shear forces are disclosed in very different embodiments. For example US Patents 5,778,843; 6,047,896 and 6,138,920. In this case, the latter introduces a rather complex control of the heating...

Problems solved by technology

[0005] Although the European patent EP-0 826 530 A2 has already proposed to combine the delivery device of the temperature-controlled fluid with the heating device working with shear force, but in this respect these two units are formed on separate components in themselves, they only act mutually. flange connections, where the controlled circulation of the temperature-regulating fluid from one component to another is as complex as the circulation of viscous liquids
