Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-cylinder air compressors used in high-demand applications, such as armored hull vehicles, face overheating issues due to high operational demands and hot environments, leading to reduced piston duty cycles before overheating and seizing occurs.
Innovation Solution
A cooling block system with two cooling nozzles on each block, connected to the crankcase of a dual cylinder air compressor, sprays coolant to ensure continuous cooling of pistons, preventing overheating and allowing continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-cylinder air compressors operate in high-demand applications with high compressed air demands, then productivity is improved, but pistons overheat and seize due to high operational demands and hot environments
Solution Approach 1:
The cooling system divides the cooling function into multiple nozzles (first cooling nozzle and second cooling nozzle) positioned at different locations within the crankcase. Each nozzle targets specific piston areas, segmenting the cooling coverage to ensure comprehensive heat dissipation across all pistons during various crankshaft rotation angles
Solution Approach 2:
The cooling blocks are positioned at the bottom of the crankcase, delivering coolant upward toward the pistons from a different spatial dimension. This bottom-up cooling approach complements traditional top-down cooling methods, creating multi-dimensional cooling coverage that ensures pistons are cooled regardless of their position in the compression cycle
2Temperature
If cooling blocks with multiple nozzles are used to cool pistons, then piston cooling effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple cooling nozzles are integrated into single cooling block assemblies that are mounted together at the bottom of the crankcase. The cooling blocks share common mounting structures and coolant delivery mechanisms, merging multiple cooling functions into unified components that reduce overall system complexity while maintaining effective multi-point cooling
Solution Approach 2:
The cooling blocks serve multiple functions simultaneously: they deliver coolant through multiple nozzles, provide structural mounting points, and can be positioned to cool multiple pistons at once. This multi-functionality reduces the need for separate cooling components for each piston, simplifying the overall cooling system design

Function Achieved in This Case
The cooling block system enables continuous operation of pistons without overheating, enhancing the duty cycle and meeting high compressed air demands by ensuring effective cooling across all rotation angles of the crankshaft.
Implementation Method 1
a first cooling nozzle near the first end having a first orifice through which the coolant is sprayed into a crankcase of the multi-cylinder air compressor. The cooling block may further comprise a second cooling nozzle near the second end having a second orifice through which the coolant is sprayed into the crankcase
