Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single cooling method (natural convection or cooling liquid circulation) is used, then the cooling system is simple, but the heat removal efficiency is insufficient
Solution Approach 1:
The patent combines two cooling methods (natural convection through heat-conducting walls and forced convection through cooling liquid circulation) into a single integrated cooling system. The connecting duct serves as both a gas passage and a heat transfer path for natural convection, while simultaneously accommodating cooling liquid flow for enhanced heat removal, thereby achieving efficient heat dissipation without significantly increasing system complexity
Solution Approach 2:
The connecting duct is designed to serve multiple functions: it acts as a gas passage between pumping chambers, a heat-conducting wall for natural convection cooling, and a conduit for cooling liquid circulation. This multi-functionality allows the same structural element to participate in both cooling mechanisms, improving heat removal efficiency without adding separate dedicated components
2Temperature
If cooling efficiency is improved by adding more cooling components, then heat removal is more effective, but the device complexity increases
Solution Approach 1:
The patent merges the connecting duct structure with the cooling system components, so that the duct itself serves as both the gas passage and the heat transfer path. The cooling liquid conduit is integrated within or alongside the connecting duct, eliminating the need for separate external cooling components and reducing overall system complexity while maintaining effective heat removal

AI summary
A multistage pump body comprises a first pumping chamber (20) and a second pumping chamber (21). A connecting duct (26a) puts an outlet (27) of the first pumping chamber (20) into communication with an inlet (28) of the second pumping chamber (21). A leak-tight conduit (40) is provided for the circulation of a cooling liquid. The connecting duct (26a) is a lateral duct of the multistage pump body. A heat-conducting wall (33) partially delimits the connecting duct (26a) and has an external surface (34) on the outside. At least a portion of the connecting duct (26a) passes between this external surface (34) of the heat-conducting wall (33) and the leak-tight conduit (40).
