A coolant pump of an internal combustion engine, with a pump housing and a hollow shaft rotatably mounted therein. Coolant is delivered via an impeller wheel from a suction connection. The flow is controlled by a guide plate on the impeller wheel that is variably displaceable axially between two end positions. The guide plate is adjustable by a push rod actuator guided in the pump shaft. The actuator has a radial piston pump integrated within the coolant pump with an intake piston and a counterpiston guided in the pump shaft, that are inserted lying opposite one another and delimit a pressure space. The pistons are enclosed outside by a linearly displaceable control element guided in the pump housing. Adjustment of the control element takes place as a function of a rotary angle of the pump shaft via an actuator unit having an electrically operated actuating element and a linear freewheel.

The tube pass tandem type tube and shell heat exchanger comprises a shell body, heat exchange tubes, baffle plates and tube plates. The tube plates are mounted at the two ends of the shell body separately, the multiple baffle plates are arranged in the shell body in the radial direction, mounting holes are formed in the tube plates and the baffle plates, and the multiple heat exchange tubes penetrate through the mounting holes of the baffle plates and are connected with the tube plates at the two ends of the shell body separately. The tube pass tandem type tube and shell heat exchanger further comprises water collecting chambers. The water collecting chambers are arranged on the outer sides of any tube plates. The water collecting chambers, the shell body, the heat exchange tubes, the baffle plates and the tube plates are combined to form sub heat exchangers, the adjacent sub heat exchangers are connected in series through barrel body connecting devices, and tube passes between the adjacent sub heat exchangers are connected into a whole. Sea water directly flows through the tube passes, so that the resistance loss of the sea water along the passes is reduced, the critical flow velocity point of self-flow circulation is reduced, and the self-flow circulation capacity is improved. The sub heat exchangers are connected in series through the barrel body connecting devices, and therefore the heat exchange function and the sealing reliability of the sub heat exchangers can be guaranteed.
