Abstract:
1. A server system, comprising: a server cabinet defining a space therein; a plurality of racks received in the space of the server cabinet, a channel defined between the racks; a plurality of servers mounted in the racks, each of the servers comprising a drawing fan; and a heat dissipation apparatus arranged under the racks, the heat dissipation apparatus comprising a fan module and two heat exchangers respectively arranged at opposite sides of the fan module, the fan module aligned with the channel for generating a flow of cooling air upward to the channel; wherein during operation of the server system, the cooling air is drawn across the servers by the drawing fans to evacuate heat from the servers and become heated air, and the heated air flows down to the heat exchangers where the heat is dissipated from the heated air such that the heated air becomes the cooling air again, wherein each heat exchanger comprises an inlet pipe adapted for injecting cold water, a plurality of absorbing fins formed around the inlet pipe, and an outlet pipe connected to the inlet pipe, and wherein during operation of the servers, the heated air flows through the absorbing fins of the heat exchangers and dissipates the heat to the absorbing fins and thus cools, while the cold water flows through the inlet pipes and absorbs the heat of the absorbing fins and warms, flowing to the outlet pipes for dissipating the heat to the exterior, wherein each of the heat exchangers further comprises a plurality of dissipating fins mounted around the outlet pipe, whereby the heat of the warm water is transferred to the dissipating fins at the outlet pipe and finally dissipated to the exterior by the dissipating fins, wherein each of the heat exchangers further comprises a heat insulating plate disposed between the absorbing fins and the dissipating fins, the absorbing fins closer to the fan module.
