になっていた。Generally, when cooling electronic devices with high heat generation density, liquid cooling is often used because air cooling lacks cooling capacity. This method includes a method in which a liquid refrigerant is poured onto a flat plate and a heating element is brought into close contact with the flat plate to transfer heat to water, and a method in which the heating element itself is directly immersed in the refrigerant to cool it. However, although this liquid cooling system has excellent cooling ability, it has the problem of condensation due to the relationship between the liquid temperature and the ambient temperature, and it is necessary to strictly control the temperature and humidity to prevent this condensation phenomenon. %vc Condensation, which causes serious damage to electronic components that dislike moisture, is a phenomenon that must be avoided at all costs. Generally, measures are taken such as placing restrictions on the temperature and humidity conditions of the room where the device is installed or limiting the water temperature to a narrow range. However, these methods are effective only when the device has reached a steady state after operation, and dew condensation often occurs during the preparation stage for starting operation of the device. In other words, this has been a problem immediately after the air conditioner starts operating in cold regions and in winter when the room temperature is low.

域が露点以下となり結露する時間帯である。Immediately after the air conditioner operation start time, the room temperature rises from T1 to the specified value T2, as shown by curve AK, but the slope is higher than curve B, which shows the temperature rise of piping and heat generating elements, which changes from TCI to Te3. big. Because the heat capacity of the piping and the refrigerant filled therein is large, and because the heating element is in close contact with the piping, it does not follow the rise in room temperature. On the other hand, the humidifier operates to maintain the specified relative humidity in order to prevent the damp air that causes malfunction of the device, and moisture is supplied to the room and the relative humidity becomes R as shown in curve C.
Changes from 1 to R2. Therefore, the dew point has a curved shape K
The temperature changes from TDI to TD2. However, the temperature of piping and heating elements does not follow the temperature of the above-mentioned temperature.
As a result, the temperature dropped below the dew point, causing condensation and causing serious damage to the equipment. The region between times C and d in FIG. 2A is a time period where the temperature is below the dew point and condensation occurs.
本発明の目的は、冷媒の温度を定められた温度まで上昇

装置を提供することにある。The purpose of the present invention is to raise the temperature of the refrigerant to a predetermined temperature, circulate it inside the device, and then start operating the air conditioner, and immediately after the air conditioner starts operating, control the air conditioner to maintain the temperature higher than the room temperature by a predetermined value. The object of the present invention is to provide a cooling device that solves the above-mentioned drawbacks.

The heater output is maintained by the controller so that the difference between the two temperatures mentioned above becomes the specified value at a specified time before and immediately after the operation of the air conditioner and humidifier at the equipment installation location. This is what I did.
次Ｋ、本発明を、図面を参照して実施例につき詳細に説

First, the cold water section consists of a pump 3 that sends cold water into the internal flow path of the cooling plate 2 that is in close contact with the heating element IVc, an expansion tank 4 that absorbs the body expansion of water, and a freon circulating through a freon cooling section that will be described later. 'fgD' is produced by evaporators 5 and K which dissipate liquid heat. Freon liquid is circulated in the Freon cooling section, and the compressor 9. Condenser 11. Evaporator 5.
In a so-called refrigeration cycle composed of an expansion valve 10,
The above-mentioned 1- removes heat from the water in the cold water section. Wind is blown onto the condenser 11 by a blower 12, and the heat in the fluorocarbon liquid is dissipated into the entire atmosphere. In this way, the heat of the heating element 1 is
The cooling plate 2 → water → evaporator 5 → fluorocarbon liquid → condenser 11 → is transferred to the air, and the heating element 1 is maintained at a predetermined temperature.

。Here, the temperature control section is composed of a water thermometer 8 and a controller 13, and the water temperature is detected by the water thermometer 8 and the output of the compressor 9 is controlled to maintain the water temperature at a predetermined value. Although such a configuration is well known in the past, the embodiment of the present invention further includes a heater 6 installed in the refrigerant (water) expansion tank 4.
Additionally, a room temperature meter (atmosphere thermometer) 7 for detecting room temperature and a heater controller 14 for controlling the output of the heater are added. With these configurations, it is possible to avoid the dew condensation phenomenon described above after the air conditioner starts operating. Figure 1(b) shows the changes in temperature and humidity in this case.
Then, the heater 6 provided inside the expansion tank 4 is energized.

The temperatures of the water and the heating element 1, which were equal to the room temperature T1 until time a, are controlled by the heater controller 14Yc so as to rise to the specified temperature TCI, as shown by a curve B.

による制御に移行すれば良い。It is safest to select a temperature slightly higher than the maximum value TD2 of the specified temperature 1-i dew point, but - if the room temperature is extremely low, it will take a long time to reach the specified value, so choose a value α higher than the room temperature. The standard redundancy value is TCI. The air conditioner starts operating at the time when the water temperature rises by α. Therefore, the time (b-a) during which the air conditioner can be operated is constant regardless of the room temperature, and even if a hot and humid condition occurs, there will be no condensation. After the air conditioner starts operating, the room temperature changes from T1 to T2 as shown in curve A and temperature/humidity curve WC. At the same time as R1-+R2 increases, the dew point also changes from TDI to TD2 like a curve, but the water temperature is α below room temperature as before the air conditioner operation.
Continue to control the temperature to keep it high. The water temperature exhibits a curve B variation and is never below the dew point at any time, so there is no conventional condensation. The control from time a to e is the same, and the water temperature is kept at α from room temperature.
The controller 13 maintains the water temperature at a predetermined value T03 at time e when the steady state trap is reached.
All you have to do is shift to control.

By maintaining this value at a high value, the surface of the heating element in the piping section does not fall below the dew point, which has the effect of preventing dew condensation.
