A temperature control device for temperature control of an electrical energy store for a motor vehicle includes a feed line element which is flushable by a temperature control fluid for the temperature control of the energy store, and which constitutes a first line element via which the temperature control fluid flowing in the feed line element can be admitted to the energy store, and includes a return line element which is flushable by the temperature control fluid, and which constitutes a second line element via which temperature control fluid flowing in the energy store can be evacuated from the energy store. The line elements are arranged in a housing which is common to the line elements, in which a housing bypass line element which is fluidically connected or connectable to the line elements is arranged, by way of which the energy store can be bypassed by the temperature control fluid.
