Numerals 6 and 6 denote heater pipes, through which a heating medium can pass. 7 is a circulation pump, 8
Is a feed pump. These pumps are of the impeller type. Reference numeral 9 denotes a three-way switching valve, and reference numeral 10 denotes a three-way switching valve with a flow rate adjusting function which operates by detecting the temperature of a hot plate or a medium. The circulating pump 7, the three-way switching valve 9, the three-way switching valve 10 having a flow rate adjusting function, and the supply pump 8 are connected to a medium supply pipe connecting the heating heater pipe and a medium path provided on the hot plate to the heating heater pipe side. Are provided in series in this order. The three-way switching valve 10 with the flow rate adjusting function has two functions of switching the flow direction of the medium and adjusting the flow rate by the signal of the temperature controller 3 which operates by detecting the temperature of the hot plate or the medium. 11 is a three-way switching valve, and 12 is a two-way switching valve. 13 is a heat storage tank for storing a heating medium. 14 is a cooling tank. Reference numeral 15 denotes a pipe for supplying a nitrogen gas to the cooling tank 14. Next, the operation of the embodiment according to the hot plate temperature raising program shown in FIG. 2 will be described.
The plate to be processed is placed on the hot plate, the hot plate is closed, the circulating pump 7 and the supply pump 8 are driven, and the three-way switching valve 9 is switched to flow the medium in the AB direction. To AB
The two-way switching valve 12 is set so as not to flow the medium, and the three-way switching valve 11 is set so as to flow the medium in the BC direction. Then, the C port of the three-way switching valve 10 is first closed by the program set in the temperature controller 3. The heating medium is a circulation pump 7 and a supply pump 8
, The hot plate 1 is rapidly heated from the heat storage tank 13 stored at a high temperature, passes through the heater pipes 5 and 6, enters the medium passage in the hot plate 1, and rapidly heats the hot plate 1. C
After flowing back to the heat storage tank 13, it is heated in the heater lines 5 and 6 and heats the hot plate 1 again. When the temperature of the heating plate 1 rises above the set temperature, the C port of the three-way switching valve 10 opens according to the signal of the temperature controller 3, and a part of the heating medium is not circulated to the heating heater pipes 5 and 6, so that the supply pump 8 By circulating between the hot plate 1 and the three-way switching valve 10 by driving, it works to reduce the rate of temperature rise of the hot plate 1. In this way,
When the temperature of the hot plate is raised at a rate of 15 ° C. per minute according to the program and reaches 260 ° C., the three-way switching valve 11 is switched from the BC direction to the BA direction to switch the heating rate. The temperature is raised to a high temperature of 380 ° C at a heating rate of 4.7 ° C per minute.

れた媒体は冷却タンク14に送られ冷却される。Since the inside of the circuit of the heating medium is pressurized with nitrogen gas, the temperature of the hot plate can be raised to a high temperature of 380 ° C.
In this case, the temperature is controlled by turning on / off the heater. The time for performing the on / off control is determined by the operation of a timer (not shown). When the timer is activated, the three-way switching valve 9 is switched so that the medium flows in the C-B direction in order to gradually cool the hot plate as shown in FIG.
The three-way switching valve 10 is moved in the AB direction and the three-way switching valve 11 is closed to switch the two-way switching valve 12 so that the medium flows in the AB direction. By driving the supply pump 8, the heated medium in the hot plate is sent to the cooling tank 14 and cooled.
