Heat exchanger

A method for tempering a fluid, flowable medium or fluid mixture, wherein the fluid is tempered by a heat exchanger, wherein the heat exchanger comprises a jacket element and an insert element, the fluid flowing in a fluid channel enclosed by the jacket element, wherein the insert element is arranged in the fluid channel, wherein the insert element contains a plurality of web elements, which are connected to the jacket element at different locations, wherein the web elements are arranged in at least two web element sets, the web elements of each web element set being arranged essentially parallel to one another, wherein angles which the web elements of different web element sets enclose with a longitudinal axis of the heat exchanger differ, wherein at least some of the web elements contain web element passages which are in fluid-conducting connection with the jacket element, so that in an operating state, a heat transfer fluid which is supplied to the jacket element can flow through the web elements, wherein the jacket element comprises a plurality of chambers for the heat transfer fluid, wherein at least one of the chambers has a plurality of inlet openings and outlet openings for the heat transfer fluid, and wherein at least one of the web elements is provided with a web element passage which does not lead into the chamber.

A heat exchanger comprising a jacket element and an insert element, the jacket element forming a fluid channel for a fluid, flowable medium or fluid mixture to be tempered, wherein the insert element is arranged in the fluid channel, wherein the insert element contains a plurality of web elements that are connected to the jacket element at different locations, wherein the web elements are arranged in at least two web element sets, the web elements of each web element set being arranged essentially parallel to one another, wherein angles which the web elements of different web element sets enclose with a longitudinal axis of the heat exchanger differ, wherein at least a portion of the web elements contains web element passages which are in fluid-conducting connection with the jacket element, so that in an operating state, a heat transfer fluid, which is fed to the jacket element, can flow through the web elements, wherein the jacket element contains a plurality of chambers for the heat transfer fluid, wherein at least one of the chambers is disposed with a plurality of inlet openings and at least two outlet openings or a plurality of outlet openings and at least two inlet openings for the heat transfer fluid, and wherein at least one of the web elements is provided with a web element passage which does not lead out of the chamber.
