Example 1:
the embodiment provides a liquid cooling energy storage battery heat management device with environment dehumidification function, which comprises a shell, wherein a refrigeration assembly, a battery cooling liquid circulation pipeline and an environment dehumidification assembly are arranged in the shell. The refrigeration assembly can generate a cold source during working, and supplies the cold source to the battery cooling liquid circulation pipeline and the environment dehumidification assembly to cool the battery cooling liquid and cool and dehumidify the air in the cabin outside the battery in the energy storage container.
Specifically, the refrigeration assembly includes a condenser, a compressor, and a heat exchanger. The air inlet end of the condenser is connected with the air outlet end of the compressor through a pipeline, the air inlet end of the compressor is connected with the first fluid outlet end of the heat exchanger through a pipeline, and the first fluid inlet end of the heat exchanger is connected with the liquid outlet end of the condenser through a pipeline. And a first throttling valve for controlling the on-off of the pipeline is arranged on the pipeline between the liquid outlet end of the condenser and the first fluid inlet end of the heat exchanger. In the present embodiment, the heat exchanger is a plate heat exchanger.
The battery cooling liquid circulation pipeline comprises a water pump and a first heater. The entry end of water pump passes through the return liquid mouth of pipeline and liquid cooling energy storage battery heat management device. The outlet end of the water pump is connected with the second fluid inlet end of the heat exchanger through a pipeline, the second fluid outlet end of the heat exchanger is connected with the inlet end of the first heater through a pipeline, and the outlet end of the first heater is connected with the liquid supply port of the liquid cooling energy storage battery heat management device through a pipeline.
In this embodiment, the energy storage container is used as a device connected to the liquid cooling energy storage battery heat management device, and then the liquid return port of the liquid cooling energy storage battery heat management device is connected to the battery liquid return port of the energy storage container through a pipeline, and the liquid supply port of the liquid cooling energy storage battery heat management device is connected to the battery liquid supply port of the energy storage container.
The environment dehumidification assembly comprises a blower, an evaporation coil, a second heater and a temperature and humidity sensor. The air outlet end of the evaporation coil is connected with the air inlet end of the compressor, and the air inlet end of the evaporation coil is connected with the liquid outlet end of the condenser. And a second throttle valve for controlling the on-off of the pipeline is arranged on the pipeline between the liquid outlet end of the condenser and the air inlet end of the evaporation coil. An air inlet of the air feeder is connected with an air return inlet of the liquid cooling energy storage battery heat management device through an air flow channel, an air outlet of the air feeder is connected with an inlet end of the second heater through the air flow channel, and an outlet end of the second heater is connected with an air supply outlet of the liquid cooling energy storage battery heat management device through the air flow channel. An air flow channel between the air outlet of the blower and the inlet end of the second heater penetrates through the evaporation coil. The temperature and humidity sensor is arranged in an air flow channel between the outlet end of the second heater and an air supply outlet of the liquid cooling energy storage battery heat management device.
In this embodiment, the air return port of the liquid-cooled energy storage battery thermal management device is connected with the in-cabin air return port of the energy storage container through a pipeline, and the air supply port of the liquid-cooled energy storage battery thermal management device is connected with the in-cabin air supply port of the energy storage container through a pipeline.
When the external environment temperature is higher or the internal temperature of the energy storage battery is higher, the refrigeration assembly works, the first throttle valve and the second throttle valve are opened, and the cold energy generated by mechanical refrigeration of the compressor exchanges heat with the battery cooling liquid in the battery cooling liquid circulation pipeline at the heat exchanger, so that the battery cooling liquid returns to the energy storage container after being cooled. Meanwhile, cold energy generated by mechanical refrigeration of the compressor can enter the evaporation coil, and when the air in the cabin of the energy storage container passes through the evaporation coil through the pipeline, the air exchanges heat with the evaporation coil, so that the air in the cabin of the energy storage container is cooled and dehumidified, and then returns to the inside of the energy storage container. It should be noted that, the temperature and humidity sensor can detect the temperature and humidity of the air going back to the energy storage container, if the temperature and humidity reach the preset range, the device can operate normally, and if the temperature and humidity do not reach the preset range, the condenser needs to be correspondingly subjected to parameter adjustment.
When the external environment temperature is lower, the first heater and the second heater can work, and the battery cooling liquid in the energy storage container is conveyed to the first heater through the water pump and returns to the energy storage container after being heated by the first heater. And air in the energy storage container is conveyed to the second heater through the blower, heated by the second heater and returned to the energy storage container.
It will be appreciated that if it is only necessary to cool the battery coolant, the second throttle valve may be closed and the first throttle valve may be opened. If the air in the cabin of the energy storage container only needs to be cooled, the first throttle valve can be closed, and the second throttle valve can be opened.
In addition, an outdoor air inlet and an outdoor air outlet are also arranged on the shell, and a condensing fan is arranged in the shell. Outdoor environment fresh air enters the air pipe through the outdoor air inlet, moves to the condenser along with the air pipe, exchanges heat with the condenser and then is discharged through the outdoor air outlet, and therefore the outdoor environment fresh air can bring the heat of the condenser out of the shell.
