きる。2. Description of the Related Art As a conventional reduced pressure evaporative cooling device, for example, there is one shown in Japanese Utility Model Laid-Open No. 3-48683. This is to reduce the pressure in the evaporative cooling chamber with a vacuum pump, supply cooling water to the cooling chamber to evaporatively cool the object to be cooled, and suck the vaporized vapor from the upper part of the evaporative cooling chamber with a vacuum pump. .. By sucking the vaporized vapor also from the upper part of the vaporization cooling chamber, new vaporization easily occurs without the vapor remaining in the vaporization cooling chamber, and efficient vaporization cooling can be performed.

この原因は、気化冷却室の下部に滞留した冷却水がその
水頭圧により真空ポンプへ優先的に吸引されるために、
ジャケット上部の蒸気あるいは残留空気を必ずしも効果
的に吸引することができないためである。In the above conventional reduced pressure evaporative cooling apparatus, the degree of reduced pressure becomes unstable, so that the degree of evaporation and vaporization becomes unstable, and uneven cooling occurs. There was a problem that it was difficult to keep the quality constant.
The reason for this is that the cooling water that has accumulated in the lower part of the evaporative cooling chamber is preferentially sucked into the vacuum pump by its head pressure,
This is because vapor or residual air in the upper part of the jacket cannot be effectively sucked.
【０００４】従って本発明の技術的課題は、気化冷却に
より生じた蒸気を確実に真空ポンプで吸引して、気化冷
却室の減圧度合の低下を防止することである。Therefore, a technical object of the present invention is to reliably suck the vapor generated by the evaporative cooling with a vacuum pump to prevent the degree of decompression of the evaporative cooling chamber from being lowered.

The evaporative cooling chamber is decompressed by a vacuum pump, cooling water is supplied to the evaporative cooling chamber to evaporatively cool an object to be cooled, and a suction pipe for sucking vaporized vapor is provided in the upper part of the evaporative cooling chamber. The suction pipe is connected to a vacuum pump via a heat exchanger and a falling portion.

The vaporized steam is heat-exchanged, that is, cooled in the heat exchanger to become condensed water, which flows down and accumulates in the falling portion. Condensed water accumulated in the falling portion has a head pressure acting according to the accumulated water level, and is reliably sucked into the vacuum pump.

The vaporized vapor that has reached the communication passage 17 is cooled by the heat exchanger 10 to become condensed water, reaches the falling portion 11, and is sucked by the ejector 32. In this case, the falling unit 1
By the action of the head pressure according to the water level accumulated in 1,
The condensed water is surely sucked into the ejector 32, and as a result, no vaporized vapor is accumulated. The cooling water that has reached the communication passage 16 is
Similarly, the ejector 32 is sucked.

When the water level of the tank 31 reaches a predetermined amount, the valve 71 is opened by the water level sensor 60 to remove it as excess water outside the system. Since the degree of vacuum of the vacuum pump device 22, that is, the degree of decompression of the ejector 32 becomes a saturated pressure with respect to the temperature of the fluid passing through the nozzle 33, the tank 3
If the temperature of the water in 1 is adjusted by supplying cooling water, it can be controlled almost arbitrarily.
