Storage tank for e.g. aqueous urea solution of exhaust gas purification device for internal-combustion engine of vehicle, has housing exhibiting highest heat conductivity and/or lowest heat capacity in refrigerant passage region
Storage tank for e.g. aqueous urea solution of exhaust gas purification device for internal-combustion engine of vehicle, has housing exhibiting highest heat conductivity and/or lowest heat capacity in refrigerant passage region
The tank (1) has a housing (4) with balancing volume (3) for expanding a fluidic operating medium e.g. AdBlue(RTM: aqueous urea solution). The housing has highest heat conductivity and/or lowest heat capacity in a refrigerant passage region (5) that is removably arranged in the balancing volume. The housing has larger wall thickness and/or a material with smaller heat conductivity and/or higher heat capacity within the region of the balancing volume than within the refrigerant passage region, and/or has a hollow chamber (10).
