Abstract:
1. Heat exchanger of an auxiliary heater which includes an auxiliary burner for mobile applications, comprising: inner and outer annularly assembled cups, each cup having a hollow cylindrical wall section having an open end area that is mountable over the burner of the auxiliary heater, and a closed bottom end section attached to the hollow cylindrical wall section at an opposite end from said open end area, wherein a flow path for a flow of a fluid heat transfer medium is formed by an annular space between the assembled cups a heat transfer medium inlet for feeding the flow of fluid heat transfer medium into the flow path, a heat transfer medium outlet for withdrawing the flow of the fluid heat transfer medium from the flow path; and a heat transfer medium directing means positioned in the annular space between the hollow cylindrical wall sections which defines an inlet-side heat transfer medium flow path and an outlet-side heat transfer medium flow path between which the heat transfer medium flows via the annular space formed between the closed end sections of the inner and outer cups, and wherein both the heat transfer medium inlet and the heat transfer medium outlet are located adjacent to the open end of the heat exchanger and are in fluid flow connection with the inlet-side and outlet-side heat transfer medium flow paths, respectively.
