きくなる欠点があった。(C) Problems to be Solved by the Invention The liquid cooling device described above cannot be used for loads that need to be maintained at a temperature higher than room temperature, such as a plastic molding die. Of course, if a heater is provided in the brine circulation path and the brine temperature is adjusted by using the heater and the evaporator together, it is possible to adjust the temperature in a wide range, but the refrigerator, liquid pump, and these control parts were housed. Since the electrical equipment box is built into the common outer case,
The inside of the outer case becomes hot, and the temperature may exceed the allowable temperature of the control parts such as thyristors for heater control that require cooling, which may adversely affect these parts. As described above, the outer case has to be large and horizontally long, which has a drawback of increasing the installation space.
