The utility model relates to the technical field of ultrapure water machines, and discloses a water temperature adjusting device of an ultrapure water machine, which comprises a shell, a normal-temperature water tank is mounted on the inner side of the shell, a water inlet pipe is mounted at the upper end of the normal-temperature water tank, and the water inlet pipe is communicated with an ultrapure water outlet of the ultrapure water machine; a heating unit and a cooling unit are installed below the normal-temperature water tank, and a distribution assembly is installed between the bottoms of the normal-temperature water tank. Through cooperative use of the heating unit, the cooling unit, the distribution assembly and the flow mixing assembly, heating and cooling of ultrapure water are achieved, precise mixing of high-temperature ultrapure water, low-temperature ultrapure water and normal-temperature ultrapure water is controlled, ultrapure water at the required temperature is obtained, the temperature adjusting precision is improved, the temperature and liquid level are monitored in real time, and the temperature adjusting precision is improved. The temperature of the ultrapure water is automatically controlled, the energy consumption required by temperature regulation is reduced, and the ultrapure water temperature regulation device has the effects of high temperature regulation precision and low working energy consumption.

This invention provides a constant temperature device, comprising: a flow guide, a temperature regulating device, and a heat exchanger. The flow guide has a liquid flow channel for flowing liquid; the temperature regulating device includes a Peltier element, a first substrate, and a second substrate, wherein the Peltier element is disposed between the first substrate and the second substrate and is respectively bonded and connected to the first substrate and the second substrate; the first substrate is disposed over the opening end of the liquid flow channel and cooperates with the liquid flow channel to form a liquid flow channel for flowing liquid; the Peltier element cools or heats the liquid flowing through the liquid flow channel through the first substrate; the design of this invention simplifies the structure of the constant temperature device, eliminates the heat-conducting plate in the prior art, and allows the temperature regulating device to directly contact the flow guide, thereby allowing the liquid in the liquid flow channel to directly contact the temperature regulating device and exchange heat, effectively reducing the thermal resistance during the heat exchange process and improving the heat exchange efficiency.
