Cooling case for computer cabinet
This is a 700~1000W air cooled water chiller, and compressor is used for production a large amount of cold capacity. It is small and light, and can be made into a 3U~4U computer case for putting into a cabinet.
This cooling system can be applied for portable low power rate laser machine, medical quick cooling system, scient test, vehicel-mounted/plane-mounted cooling.
1. Features
| ①Enerfy conservation: Using frequncy conversion dual system design, when the power rate is very low, only one system will work. So it can save energy and backup for each other. | ②High efficiency： The refrigeration efficiency of the small micro refrigeration system is about 2, which is 5 times of the semiconductor refrigeration efficiency, and is far higher than other refrigeration and cooling methods. |
| ③High pump head： Brushless variable frequency pump can provide high hydraulic head and big flow rate. | ④Precisely control temperature: Temperature can be set on the LCD, and temperature controlling error is ±1℃. |
| ⑤Design as 3U computer case, easy for install： The shape is same as a computer case, it can be installed on the cabinet directly. | ⑥Safe and reliabel: |
| ⑦Good environmental adaptability： It can work at 0.5 bar(high altitude) ~1 bar environment. |
