AI Technical Summary

Technical Problem

In fuel cell engines, the intercooler needs to bear increasingly large heat exchange and coolant flow, resulting in increased power consumption of the water pump and poor energy recovery efficiency of the expander.

Method used

An intercooler is designed, and its cooling path is divided into two parts: one part of the outlet gas passing through the low-temperature gas inlet is pre-cooled, and the other part of the coolant passing through the cooling pipeline is deeply cooled. This design allows high-temperature gas to be pre-cooled by the outflow gas first, and then deeply cooled by the coolant, reducing the heat exchange of the coolant, thereby reducing the intercooler's demand for coolant flow and reducing the power consumption of the water pump.

Benefits of technology

Through this design, the power consumption of the water pump is reduced, the energy recovery efficiency of the expander is improved, and the overall engine efficiency is improved.

Abstract

The utility model relates to the technical field of fuel cells, and discloses an intercooler and a fuel cell engine system applying the intercooler, the intercooler is suitable for an engine, the intercooler comprises an intercooler body, and the intercooler body is provided with a high-temperature gas inlet and a high-temperature gas outlet; the intercooler body is provided with a low-temperature gas inlet and a low-temperature gas outlet, and pile outlet gas introduced through the low-temperature gas inlet is used for precooling high-temperature gas in the intercooler body. According to the intercooler, a cooling path of an intercooler body is divided into two parts, a cooling medium of one part is out-of-pile gas introduced through a low-temperature gas inlet, the cooling medium of the other part is cooling liquid introduced through a cooling pipeline, high-temperature gas entering the intercooler body is pre-cooled through the out-of-pile gas and then is deeply cooled by the cooling liquid, and the high-temperature gas enters the intercooler body. The heat exchange amount of the cooling liquid is reduced, the demand of the intercooler for the flow of the cooling liquid is reduced, and therefore the power consumption of the water pump is reduced.
