Description

Technical Field

[0001] This utility model belongs to the field of water sample constant temperature technology, specifically a generator constant cooling water sample constant temperature and cabinet cooling device. Background Technology

[0002] Generators generate a large amount of heat during operation. At this time, the generator sample water is used to cool the generator sample water. As the temperature of the generator sample water increases, the cooling effect will become worse. Therefore, it is necessary to cool the generator sample water. Generally, the generator shut-off cooling water is used as the cooling water to cool the generator sample water. Since the generator shut-off cooling water return temperature is relatively high (about 60°C), and the cooling water temperature is also relatively high in summer (about 35°C) due to the influence of ambient temperature, and the temperature difference between day and night is large, the cooling effect is not good, the temperature of the shut-off cooling water sample cannot be kept constant, and the error in the dissolved hydrogen measurement data is also large.
