[0023] In this setting, the utility model adopts support between the pipes through heat-conducting supports, and at the same time, the pipes between the liquid water and the cooling oil adopt heat-conducting materials, which fix the internal structure and increase the heat conduction effect; the cooling oil passes through the oil inlet cavity 3 in the oil inlet pipe 8, enters the oil cavity 11 at the end, contacts the wire protection layer 6 outside the wire 7, and absorbs its heat. At the same time, the cooling oil will transfer the heat to the liquid water in the water-cooling cavity 2 through the heat-conducting pipe 10, and use the principle that the specific heat capacity of liquid water is greater than the specific heat capacity of cooling oil to reduce the temperature of the cooling oil and increase its heat absorption effect.

[0029] In this arrangement, the cooling oil will transfer heat to the liquid water in the water-cooling chamber 2 through the heat pipe 10, and use the principle that the specific heat capacity of liquid water is greater than the specific heat capacity of cooling oil to reduce the temperature of the cooling oil and increase its heat absorption effect. At the same time, because the liquid water is on the periphery, the heat dissipation effect is better.
