With the valves 4 and 48 closed, the first and second on-off valves 3
Open 8,40. In this state, the cooling water from the cooling water supply source (not shown) is passed through the first cooling water pipe 34 from the cooling water inlet 18C to the fourth collecting pipe 80 and the fifth connecting pipe 78 in this order. Then, it is introduced into the second pipe 54 and flows therein. On the other hand, by driving the feed pump 24, the heat medium flowing in the first pipe 52 located in the second pipe 54 is cooled by exchanging heat with the cooling water flowing in the second pipe 54. The heat medium cooled in this way is transferred from the heat medium outlet 18A to the first
The heat medium is introduced into the hot plate 12 of the hot press body 14 from the heat medium introducing port 14 </ b> A through the heat medium pipe 20 of FIG. In this way, the hot plate 12 is cooled. The second pipe 5

Among these, with only the third on-off valve 44 closed, each electric heater 30 is energized to generate heat. Then, by this, the feed pump 24 is driven to bring it from the second heat medium conduit 22 to the second collecting pipe 70 via the heat medium return port 18B and to the second collecting pipe 70 via the second connecting pipe 68. The heat medium introduced into the first pipe 52 is heated by the electric heater 30 and flows up to a predetermined temperature while flowing through the first pipe 52.

る。In the above heating operation of the heat medium, as described above, in the first pipe 52 through which the heat medium flows,
The electric heater 30 is disposed except for the arc-shaped elbow portion 52c. As a result, the heat transfer area as a heat exchanger has a sufficient amount, and while a reliable heating operation is achieved,
Since the electric heater 30 is present in the first pipe 52, the cross-sectional area of the first pipe 52 through which the heat medium passes is narrowed. Volume) becomes smaller. As a result, thermal efficiency is increased and energy consumption is reduced. In addition, this will reduce the electricity bill and improve the economic efficiency.

になる。Further, as described above, in the heating operation and the cooling operation, the heat medium circulates through the same pipe lines 20 and 22, so that the flow of the heat medium for heating and cooling the heating plate 12 is performed. There is no need to switch the path, which simplifies the configuration.

し、設計状の自由度が増すことになる。Further, the electric heater 30 is arranged in a state of being divided into two in each first pipe 52. For this reason, even if it expands during heat generation, its tip is set as a free end, so expansion movement of this is allowed without problems, and the tolerance for expansion during heat generation is improved. The degree of freedom of the situation will increase.

る。For example, in the above-described embodiment, each first pipe 52 has a first straight line portion 52 and a second straight line portion 52.
Although it has been described that the two electric heaters 30 are provided corresponding to a and 52b, respectively, the present invention is not limited to such a configuration and is shown as a modified example in FIGS. 5 and 6, for example. Similarly, it may be configured by the substantially U-shaped sheathed heater 84 set coaxially with the first pipe 52. With this configuration, the amount of the heat medium contained in the first pipe 52 is smaller than that in the above-described embodiment, and the energy saving effect and the economical efficiency are further improved.

少なくて済む事になる。As described above in detail, according to the present invention,
The cross-sectional area of the first pipe through which the heat medium passes is set narrow by the heating means. As a result, the volume of the heat medium passed through the first pipe is set to be small, and therefore, the energy consumption for heating the heat medium having such a small volume can be reduced, and The electricity bill will be small.
