Water-cooling condenser

The invention relates to a water-cooling condenser. The water-cooling condenser comprises a water inlet pipe, a water inlet branch pipe, a cooling pipe, a water outlet branch pipe, an annular gathering pipe, a water outlet pipe and a separating plate; the periphery of the water inlet pipe is surrounded by the annular gathering pipe coaxially arranged with the vertical water inlet pipe, the water inlet pipe and the annular gathering pipe are communicated through a plurality of radially-radiated circular pipes, and a plurality of cooling pipes are vertically arranged at proper positions between the circular pipes; a separating plate is arranged in the middle portion of the cooling pipe, the upper end portion of the separating plate is connected with the upper end portion of the cooling pipe, and a gap is reserved between the lower end of the separating plate and a base plate of the cooling pipe; and a plurality of inclined spoilers are arranged on the inner wall of the cooling pipe and the two sides of the separating plate respectively. Radially-radiated circular pipe passages are divided into two parts through the separating plate, the circular pipe communicated with the water inlet pipe is the water inlet branch pipe, and the circular pipe communicated with the annular gathering pipe is the water outlet branch pipe; and the water outlet pipe arranged on the outer side of the annular gathering pipe is communicated with a pipe of the annular gathering pipe. The water-cooling condenser has the beneficial effects that the interior of a component which is complex in structure and narrow in cooling space can be cooled.
