Installation Requirements for the Water-Cooled Module
- Installation environment: Enclosed indoor environment in which the temperature and humidity can be controlled within the ranges of 4°C to 45°C and 5% RH to 90% RH respectively. If the indoor installation position is ventilated, it should be more than 3.7 km away from the sea or pollution sources (such as salt lakes, chemical plants, mineral plants, thermal power plants, and coal mines).
- Take antifreezing measures for cooling water pipes if the water-cooled module is installed in low temperature environments (4°C). To prevent ethylene glycol solution from corroding pipes, corrosion inhibitor should be mixed into the glycol solution. For details about the mixing scheme, consult the ethylene glycol vendor.
- Wrap thermal insulation layers for pipes connecting the water-cooled module.
- The upstream supply water pressure for the water-cooled module shall be greater than or equal to 0.35 MPa.
- The water quality of the water-cooled module shall meet the following requirements.

- A maximum of four water-cooled modules can be stacked, as shown in the following figure.Figure 4-18 Stacking scenario
(1) Water strainer
A water strainer with 20 meshes and pressure resistance of 1.6 MPa or higher is recommended onsite. Pressure resistance of the water strainer is determined by site requirements. The water strainer should be installed on the external water inlet pipe and close to the smart cooling product.
- The water-cooled module should be installed on a concrete base. The base requirements are as follows.Figure 4-19 Concrete base dimensions (unit: mm)
(1) Mounting hole: 4 x M12
