Technical Field

[0001] The utility model relates to a high-efficiency heat exchanger which is easy to clean and belongs to the technical field of heat exchangers. Background Art

[0002] The shell and tube heat exchangers currently used on water-cooled units cannot be disassembled for cleaning. As the dirt inside the heat exchanger cannot be removed in time, the heat exchange capacity of the heat exchanger decreases year by year, increasing the operating power consumption of the unit and causing the operating costs to increase year by year. In the case of severe scaling of the heat exchanger, the unit cannot be used normally and has to be replaced with a new heat exchanger or the entire unit.

[0003] At the same time, the existing shell and tube heat exchanger has the problem of low heat exchange efficiency. This is because after the hot water enters the heat exchanger, it only flows to one side of the heat exchanger close to one end of the water inlet pipe, resulting in the other side of the heat exchanger far away from the water inlet pipe not being fully utilized, and the hot water and the cold medium pipe cannot be fully contacted.

[0004] Therefore, how to provide a high-efficiency heat exchanger that is easy to clean is the research purpose of the utility model. Utility Model Content

[0005] In view of the deficiencies of the above-mentioned technology, the utility model provides an efficient heat exchanger which is easy to clean. Hot water flows evenly to the inside of the heat exchanger through the water separator at the bottom of the heat exchanger, so that the hot water is in full contact with the refrigerant medium pipe, thereby improving the heat exchange efficiency of the heat exchanger.

[0008] Furthermore, the top end of the water outlet pipe contacts the top end inside the heat exchanger shell, and the bottom end passes through the water divider and extends to the outside of the heat exchanger shell. The top end of the water outlet pipe is provided with a plurality of groups of connected water inlet holes along its circumference.

[0009] Furthermore, the middle parts of the head bottom plate and the diverter plate are provided with through holes for the water outlet pipe to pass through.
