Heat exchanger with temperature adjusting function

The heat exchanger with the temperature adjusting function comprises an installation assembly, a temperature control assembly and a heat exchange assembly, the installation assembly is composed of an installation block, a first flow channel, a second flow channel and an installation shell, the installation shell is arranged in the center of the top of the installation block, and the first flow channel and the second flow channel are formed in the two sides of the bottom of the installation block respectively. According to the utility model, the installation assembly and the temperature control assembly are additionally arranged to form a medium circulation discharge structure, a hot side medium directly penetrates through the thermostat shell to be discharged from the hot side outlet when heat exchange is not needed, and the connection notch is blocked by the baffle plate when heat exchange is needed; a communication structure of the temperature control assembly is blocked, so that a hot-side medium flows int
