Heat exchanger and water heater with same

Abstract

The invention discloses a heat exchanger and a water heater with the heat exchanger. The heat exchanger comprises a shell, a heat exchange assembly, a water inlet pipe and a water outlet pipe. The shell is provided with a water inlet and a water outlet, the heat exchange assembly is arranged in the shell, and the heat exchange assembly is communicated with the water inlet and the water outlet. One end of the water inlet pipe is connected with the water inlet, and one end of the water outlet pipe is connected with the water outlet. Wherein the water inlet pipe and / or the water outlet pipe comprises a copper pipe section, a joint section and a stainless steel section, one end of the joint section is connected with the copper pipe section, the other end of the joint section is connected with the stainless steel section through brazing, and the copper pipe section is connected with the water inlet or the water outlet. According to the heat exchanger and the water heater with the heat exchanger, at least one of the water inlet pipe and the water outlet pipe is composed of the stainless steel section, the copper pipe section and the joint section, and the production cost is reduced. And good weldability is achieved between the joint section and the copper pipe section, and the connecting difficulty of the stainless steel section and the copper pipe section can be reduced.
