The heat exchanger is usually made of metal materials, and it transfers the heat generated by the combustion of gas to water or other fluids flowing through its pipes. According to the utility model with the patent authorization announcement number CN203928413U, a gas boiler cast aluminum heat exchanger is disclosed, including a front module, a middle module and a back module, each module is provided with a water channel inside, and a flue is formed between adjacent modules. The front module, the middle module and the back module are all die-cast, and the water channel consists of a total water inlet channel, a heat exchange channel and a total water outlet channel. The heat exchange channel in each module is connected with the total water inlet channel and the total water outlet channel, and the total water inlet channels of adjacent modules are connected, and the total water outlet channels of adjacent modules are connected. Since the cast aluminum heat exchanger adopts a die-casting process instead of a sand casting process, the production efficiency is improved and the manufacturing cost is reduced.
