Precipitation Rate | Ambient temperature cooling time: RT→ -50°C under the average no-load condition of the whole process ≧1°C/min Water temperature cooling rate: RT→1℃, average≧0.7℃/min About 25mm/h, raindrop size is adjustable |
Precipitation Cycle | 1min~99h can be set arbitrarily |
Precipitation Agency | The rainfall device is designed on the top of the box. In order to prevent the water pipes from freezing and the water pipes hidden in the insulation layer of the constant temperature room, a corresponding number of drip holes are made, and seamless welding is used around the holes and the water pipes to prevent water from flowing into the insulation layer. , There is a high-temperature water pump on the side to pump water through the water pipe to drip rain into the box. When the precipitation stops, the water in the water pipe will automatically flow back, and there will be no water in the water pipe, which can ensure that the nozzle of the water pipe will not freeze under the low temperature of -55 degrees. |
Ice Fog | The design of the ice fog is the same as the design principle of the precipitation structure, but the ice fog has an additional nozzle, and the high-pressure water pump is used to turn the water into a mist through the nozzle and fall into the box. (If it falls into the box in the form of mist at -55 degrees, it will affect the cooling of evaporation, which will cause ice on the evaporator, thereby affecting the cooling. Larger will affect the uniformity of temperature) |
