The liquid pipe in the evaporator is disposed adjacent to the refrigerant conduit in the evaporator, so that the refrigerant in the refrigerant conduit in the evaporator cools or heats the liquid in the liquid pipe. It should be further noted that, the arrangement of the first check valve 1# can prevent the liquid in the first liquid guiding pipe from flowing back to the battery liquid cooling plate, so as to ensure that the liquid in the first liquid guiding pipe stably flows, and prevent the first water pump P1 from being damaged due to reverse impact of the liquid.

When the liquid in the battery liquid cooling plate needs to be heated, the refrigerant in the refrigerant conduit runs in the reverse direction, so that the heating of the liquid in the battery liquid cooling plate can be realized, and details are omitted here.
