The refrigerant vapor condenses on the outer surface of the pipe, and the cooling water flows in the pipe under the action of the pump. The refrigerant vapor enters the person from the upper intake pipe, condenses into liquid, and flows into the reservoir through the outlet pipe at the lower part of the cylinder. Both ends of the barrel of the condenser are sealed with an end cover, and a water separation partition is used in the end cover to realize the multi-pipe flow of the cooling water. The number of tube bundles of the condenser is even, so that the inlet and outlet of the cooling water can be arranged on the same end cover, and the lower inlet and the upper outlet.

The vertical shell and tube condenser is installed upright and has no end cover at both ends. The refrigerant vapor enters the outer tube space in the cylinder from the upper inlet pipe in the middle of the condenser shell. The condensed liquid flows from the top down along the outer wall of the tube, gathers at the bottom of the condenser, and enters the liquid reservoir through the outlet pipe. The cooling water enters the heat exchange tube of the condenser from the upper part, flows down the tube wall in a film shape, and is discharged into the pool below the condenser for recycling.

The spiral body of the ladybird condenser consists of a spiral baffle and a baffle tip lap. The spiral baffle is fixed by the distance tube, and the condensing tube passes through the spiral baffle one by one. The spiral baffle and the tube plate together serve as the support of the condensing tube bundle. The spiral baffle is fan-shaped, and each baffle forms a certain Angle with the axis of the shell, and the adjacent baffle is connected at the periphery, so that the outer circle forms a continuous helix. This device mode changes the flow state of the shell path fluid, thereby improving the heat transfer efficiency of the shell path and reducing the pressure drop of the shell path fluid.
