Description

Thermosyphon heat exchanger

This creation is related to a thermosiphon heat exchanger, especially a thermosiphon heat exchanger with asymmetric internal and external heat exchange efficiency.

Heat exchangers are often used for heat dissipation in sub-equipment cabinets. This creation is about thermosiphon heat exchangers. A general thermosiphon heat exchanger is divided into an inner circulation side and an outer circulation side by partitions. The inner circulation side is connected to the internal space of the cabinet, and the outer circulation side is connected to the external environment. There is no air flow between the inner circulation side and the outer circulation side. The inner circulation side and the outer circulation side are respectively provided with heat exchangers, and the heat exchangers on both sides are connected through the baffle through pipes. The working fluid is injected into the heat exchanger, and the heat exchanger on the inner circulation side exchanges heat with the hot air in the cabinet to take away heat energy. The heat energy vaporizes the working fluid and flows through the pipeline to the heat exchanger on the outer circulation side. The gaseous working fluid passes through the heat exchanger on the outer circulation side to exchange heat with the environment to cool and condense. The liquid working fluid in the heat exchanger on the outer circulation side passes through the pipeline to return to the heat exchanger on the inner circulation side to perform the next heat exchange cycle.

Existing thermosiphon heat exchangers are generally equipped with the same symmetrical heat exchanger and fan on the inner and outer circulation sides, respectively, so the heat exchange capacity on the inner and outer circulation sides is the same. However, generally speaking, the heat exchange efficiency of evaporation and condensation is not the same.
