When the fluid passes through the three-way valve 61, the fluid flows to the heater 31 without flowing through the second return pipe 43. At this time, the first control valve 62 is opened. To allow the fluid to flow from the heater 31 to the inflow communication tube 24, the second control valve 63 is closed to prevent the fluid from the cooler 41 to the second control valve 63 from flowing to the second contact point P2, as shown in FIG.

Thus, the second embodiment achieves a better thermal conductivity by providing two such copper foils 23.

Through the above description, the advantages of the present invention are summarized as follows:

1. In the conventional plate press, the fluid passes through the heater 31 in both the heating cycle state and the cooling cycle state, so that the temperature in the heater 31 has been lowered in the heating cycle state. Up to the cold pressing temperature, it takes extra time and energy to raise the temperature of the fluid and the inside of the heater 31 to the hot pressing temperature, and in the cooling cycle state, it takes extra time and energy to The temperature inside the heater 31 and the fluid is lowered to the cold pressing temperature. The present invention is connected to the first inlet pipe 32 by the second inlet pipe 32, and is matched with the three-way valve 61 so that the fluid is in the When the cooling cycle state is not passed through the heater 31, the temperature inside the heater 31 can be maintained at a high temperature, thereby saving time and reducing energy consumption.

2. By the first control valve 62 and the second control valve 63, the fluid between the heater 31 and the first control valve 62 does not flow into the first introduction pipe 32 in the cooling cycle state to cause a pipe The internal temperature rises, and in the heating cycle state, the fluid between the cooler 41 and the second control valve 63 does not flow into the first introduction pipe 32, causing the temperature inside the pipe to drop, further achieving the energy saving effect.

3. The expansion barrel 71 of the voltage stabilizing unit 7 enables the expansion barrel 71 to adjust the pressure inside the tube when the temperature is changed, thereby avoiding damage to the components due to pressure changes in the tube, thereby achieving safer use. .

4. The novel structure is simplified, and the effect of saving time and reducing energy consumption can be achieved.

In summary, in the energy-saving plate press of the present invention, since the second introduction pipe 42 communicates with the first introduction pipe 32 and is isolated from the first return pipe 33, when the cooling cycle state is performed, the cooled fluid does not pass through the The heater 31, therefore, does not require extra time and energy to cool the inside of the heater 31 in the state of the cooling cycle, and it does not take extra time to heat the fluid in the heater 31 in the heating cycle state. The cold pressing temperature starts to heat up, and the effect of saving time and reducing energy consumption is achieved, so that the purpose of the novel can be achieved.
