1. A cooling system, comprising:
a heat exchange wall separating a primary air channel and a secondary air channel that are arranged in parallel;
a plate positioned on an end of the heat exchange wall, wherein valves are positioned on the plate and each valve is configured to open and close a respective primary air inlet; and
a partition wall separates the secondary air channel and working (wet) air channel that are arranged in parallel and connected at the plate,
a first side fluidly connected to a first space and a second side fluidly connected to a second space, wherein the plate is positioned at the second side, and the partition wall extends from the first side towards the second side and is spaced apart from the plate;
a silica gel layer directly adjacent to and continuous with the working air channel, the partition wall defines the secondary air channel along the working air channel from the first side to the second side and then along the working (wet) channel from the second side to the first side, the working (wet) air channel is positioned between the heat exchange wall and the partition wall, and the silica gel layer comprises a silica gel in particulate form and a continuous moisture-permeable polymer membrane layer on an outside surface of the silica gel layer;
wherein a plurality of the heat exchange walls is surrounded 360 degrees by the working (wet) air channel, and the plurality of the heat exchange walls each define a respective primary air channel surrounded 360 degrees by the working air channel;
a respective primary air inlet, for each primary air channel, positioned on the first side and configured to receive a primary air from the first space; and
a respective primary air outlet, for each primary air channel, positioned on the second side and configured to discharge the cooled primary air into the second space;
wherein the primary air channel is surrounded 360 degrees by the heat exchange wall which is surrounded by the working air channel by more than 350 degrees.
