Referring to fig. 1 to 2, a cooling device of a liquid cooling energy storage system includes a water chiller 2, a wind-water heat exchanger 3, a plurality of liquid cooling plates 4, a liquid cooling pipeline between the water chiller and the wind-cooling heat exchanger, and a blower 5;
wherein the energy storage system is arranged on the energy storage cabinet 1, the energy storage cabinet 1 comprises a battery compartment 11, a water chilling unit compartment 12 and a PCS (energy storage converter, power Control System) power distribution compartment 13, the energy storage system comprises a battery and a PCS, the battery comprises a plurality of PACKs, the battery and the wind-water heat exchanger 3 are configured in the battery compartment 11, the water chilling unit 2 is configured in the water chilling unit compartment 12,
each liquid cooling plate is configured on each PACK, the air blowing device is configured on the air-water heat exchanger and/or the PCS and is used for guiding hot air around the PCS to the air-water heat exchanger, the air-water heat exchanger absorbs heat in the hot air and outputs cold air to be led into the PCS, so that the PCS cooling is realized,
the wind-water heat exchanger 3 is connected with the water chilling unit through the liquid cooling pipeline and connected with the liquid cooling plate 4 on each PACK, so that cold water in the water chilling unit flows into the liquid cooling plate on each PACK from the wind-water heat exchanger through the cold pipeline, and the temperature of each PACK is reduced.
The battery compartment and the PCS power distribution compartment have sealing characteristics, and sealing strips are arranged on the cabinet doors of the battery compartment and the PCS power distribution compartment, so that the battery compartment, the water chilling unit compartment and the PCS power distribution compartment can intercept the invasion of moisture outside the energy storage cabinet.
The pipeline and the circuit between the water chilling unit cabin and the battery cabin are of a sealing design, so that the moisture in the water chilling unit cabin is reduced from immersing into the battery cabin, and a distribution cable leading-out position in the PCS cabin is provided with fire-proof mud for sealing.
The cooling water unit cabin is provided with a ventilation shutter which is of a semi-sealing design.
The battery compartment is configured at the upper left side of the energy storage cabinet, the water chilling unit compartment is configured at the right side of the battery compartment, the PCS power distribution compartment is configured at the lower side of the energy storage cabinet and is positioned below the battery compartment and the water chilling unit compartment, the wind-water heat exchanger is configured at the PCS power distribution compartment and is positioned below the PCS, and the wind-water heat exchanger is connected with the condensation collecting device, so that condensation generated by the wind-water heat exchanger can be directly gathered by the condensation collecting device and then discharged out of the energy storage cabinet through the drain hole.
Firstly, introducing heat generated by PCS into a wind-water heat exchanger through an air cooling channel, namely, firstly cooling the PCS, wherein the wind-water heat exchanger can cause the temperature of the liquid of the heat exchanger to rise through heat exchange, and the generation of condensation is also transferred to the wind-water heat exchanger (because the temperature difference is the largest), namely, the water outlet temperature of the wind-water heat exchanger is slightly raised relative to the water outlet temperature of a water chilling unit (assumed to rise from 18 ℃ to 20 ℃);
then, we cool the PACK in the battery compartment again, thereby reducing the temperature difference relative to the PACK, and thus reducing the generation of condensation at the PACK.
The cold liquid output by the cold water machine set through the liquid cooling pipeline passes through the wind-water heat exchanger, so that in the wind-water heat exchanger, heat exchange cooling is carried out on hot air led in from the PCS, then, cold night current output in the wind-water heat exchanger enters the plurality of liquid cooling plates to carry out heat exchange with each PACK, and the cold liquid returns to the cold water machine set after converging. (so that the condensation occurs with a greater probability at the wind-water heat exchanger than at the battery PACK, combined with a location design to facilitate collection of the condensation and reduce the likelihood of the condensation contaminating other equipment).
As shown in fig. 2, the water exiting the chiller (assuming 18 degrees celsius) passes through the PCS and then through the battery compartment (specifically, the parallel cold plates passing through each PACK in the battery compartment). The advantage of doing so has changed the position that the condensation produced, shifts the position that the condensation produced by each PACK department to wind water heat exchanger department, and is further, on combining structural design, put wind water heat exchanger in the rack below to the condensation of easily collecting the production and in time discharge the rack, the effectual possibility of avoiding the condensation to drip on other electrical equipment on the rack has effectively promoted system security.
