Server system with heat dissipation apparatus

A server system, comprising:

• a server cabinet comprising a top plate, a bottom plate, and two opposite end plates each extending between the top and bottom plates;
• a support plate connected between the end plates to divide an interior of the server cabinet into an upper portion over the support plate and a lower portion under the support plate, wherein a plurality of ventilation holes is defined in the support plate to intercommunicate the upper portion and the lower portion;
• two racks received in the upper portion between the end plates, a channel defined between the two racks, and a passage defined between each of the end plates and one corresponding neighboring rack;
• a plurality of servers mounted in the racks, each of the servers comprising a drawing fan;
• and a heat dissipation apparatus disposed in the lower portion, the heat dissipation apparatus comprising a fan module aligned with the channel and two heat exchangers respectively arranged under the two racks;
• wherein during operation of the server system and the servers, cooling air is drawn up from the lower portion to the channel by the fan module and moved across the servers by the drawing fans to exhaust heat from the servers such that the cooling air becomes heated, and the heated air flows down along the passages to the heat exchangers where the heat is dissipated from the heated air which thus 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 to absorb the heat of the absorbing fins and warms, flowing to the outlet pipes and dissipating heat thereat, wherein each heat exchanger further comprises a plurality of dissipating fins around the outlet pipe, the heat of the warm water is transferred to the dissipating fins at the outlet pipe and finally to the exterior by the dissipating fins, wherein each heat exchanger further comprises a heat insulating plate disposed between the absorbing fins and the dissipating fins, the absorbing fins closer to the fan module, the outlet pipe arranged below the inlet pipe. er to the fan module, the outlet pipe arranged below the inlet pipe.
