Product Introduction：
This product is capable of both cooling and heating functions. The cooling function effectively addresses issues such as thermal runaway, severe capacity degradation, and product lifespan reduction caused by excessive temperature during battery charging and discharging. The heating function effectively resolves the problem of batteries not being conducive to charging and discharging in low-temperature environments and cold regions, ensuring normal battery charging and discharging, and allowing the battery to operate efficiently within an appropriate temperature range.
The product includes a refrigeration and heating circuit and a battery pack cooling water circuit, with the two circuits exchanging heat through a plate heat exchanger (Chiller). The refrigeration circuit generates low temperatures, and the battery pack cooling water circuit cools the battery pack, after which the cooling water is heated and then cooled again through the plate heat exchanger, achieving dynamic equilibrium and ultimately cooling the battery. The refrigeration system module consists of components such as a compressor, condenser, plate heat exchanger, and throttle valve; the water circuit module consists of components such as a water pump, PTC heater, and water pipes!
Core advantages:
Efficient heat dissipation: The specific heat capacity of liquid is much higher than that of air, allowing for more efficient transfer of large amounts of heat, making it particularly suitable for thermal loads at the 5kW level.
Compact layout: The "horizontal" design reduces the overall height, making it suitable for 19-inch standard cabinets, equipment bottom installation, or situations where space height is limited.
Low noise: Compared to large fans with equivalent cooling capacity, liquid cooling systems primarily generate noise from the water pump and a small number of fans, making them generally quieter.
Precise temperature control: It can achieve liquid temperature control with an accuracy of ±0.5°C or even higher, ensuring that the cooled equipment is maintained at its optimal operating temperature.
Long-distance heat transfer: The cooling liquid can be transported through pipelines over long distances, discharging the heat to a more suitable location (such as outdoors), thereby optimizing the environment of the computer room.
