Abstract:
1. A cooling plate structure of a cooling apparatus for cooling a plurality of heat generating elements, comprising: a cooling plate which has an excellent heat conductivity and an outer surface with which the plurality of heat generating elements make intimate contact; and at least one refrigerant circulating conduit which has an excellent heat conductivity, which extends in the cooling plate, and which includes a refrigerant introducing port and a refrigerant discharging port, both of the introducing and the discharging ports disposed adjacently side by side on the outer surface of the cooling plate in an exposed state, a flow-in part extending from the refrigerant introducing port to an intermediate position of the refrigerant circulating conduit and a flow-out part extending from the intermediate position to the refrigerant discharging port, wherein the intermediate position of the refrigerant circulating conduit is not located between the refrigerant introducing port and the refrigerant discharging port in the cooling plate, the flow-out part returns from the intermediate position toward the refrigerant introducing and discharging ports along the flow-in part while the flow-out part is adjacent the flow-in part with a gap therebetween, and the plurality of heat generating elements are disposed along both of the flow-in part and the flow-out part of the refrigerant circulating conduit at an intermediate portion between a flow-in part corresponding portion and a flow-out part corresponding portion which respectively correspond to the flow-in part and flow-out part of the refrigerant circulating conduit on the outer surface of the cooling plate.
