The invention discloses an automobile liquid heater. The automobile liquid heater comprises a shell, a bottom cover and a top cover, wherein the bottom cover and the top cover are arranged on the twosides of the shell. The side, close to the bottom cover, of the shell is provided with a first containing cavity, and the first containing cavity is internally provided with a circuit board. The side,close to the top cover, of the shell is provided with a second containing cavity, and the second containing cavity is internally provided with a heating assembly. The shell is further provided with awater inlet and a water outlet which communicate with the second containing cavity. The top of the open end of the first containing cavity is provided with a first stepped groove, and the top of theopen end of the second containing groove is provided with a second stepped groove. The bottom cover and the top cover are correspondingly fixed into the first stepped groove and the second stepped groove in an up-down lap joint friction welding manner. The automobile liquid heater is simple in structure, the airtight performance, the watertight performance and the lasting quality of a shell and cover plate connection structure can be effectively improved, and the machining cost is reduced.
