Device for Mixing and Heat Exchange

Method for the manufacture of a device for mixing and heat exchange which contains a mixer insert (3) and a cladding element (2) which is manufactured at least partially segmented as a monolithic structure from the mixer insert and the cladding element by a casting method, whereby the monolithic structure comprises a first and second group (5, 6) of web elements (9, 10) which are arranged in an angle not equal to zero with respect to the main direction of flow and a cladding element (2) which is fixedly connected to at least a portion of the web elements, whereby the web elements comprise at least partially channels, which are used in the operative state by a heat exchange fluid, which is not in connection with the flowable medium, said flowable medium flows around the web elements, whereby the channels extend from a first end (13) of the web element (11) to a second end (14) of the web element (11), whereby the cladding element (2) comprises a corresponding channel which is in connection with the first end (13) and the second end (14) of the web element (11) whereby the transition from at least one of the first (13) and second ends (14) of the web element to the corresponding channel in the cladding element (2) is free from gaps, whereby the length of the channel is greater than the mean diameter of the cladding element (2), if the web element (9, 10) contains the longitudinal axis (4), whereby a casting mold is produced during the casting method by means of a wax body, a ceramic shell is applied onto the wax body and subsequently the wax is removed, the ceramic shell is manufactured by a burning process and the ceramic shell is filled with casting material and the casting material is hardened by cooling and the ceramic shell is removed after the casting material has hardened.
