Liquid Cooling TRIZ Cases
- Cylinder Head EGR Cooler Integration for Compact Diesel Layout
Coupling an EGR cooler directly to a cylinder head with integrated passages reduces thermal deformation while maintaining rigidity in compact diesel engines.
- Marine Engine Cooling Jacket Core Stability During Casting
Monolithic cooling jacket core with bridged portions prevents movement and breakage of split-flow paths during marine engine casting.
- Coolant Flow Control via Stored Energy Estimation
Estimating material temperature from restored coolant power delays water pump activation, reducing energy consumption while maintaining thermal reliability.
- Exhaust Side Block Insert for Cylinder Block Cooling
An exhaust side block insert divides the water jacket into upper and lower coolant flow passages to manage cylinder block temperatures.
- Marine Engine Cooling Jacket with Exhaust Conduit Heat Recovery
Parallel cooling branches and bypass circuits maintain uniform cylinder temperatures while preventing oil dilution in marine engines.
- Turbocharger Engine Structure with Integrated Fluid Channels
An engine structure integrates attachment means and curvilinear fluid channels to secure a turbocharger unit while supplying lubrication and coolant.
- Engine Cooling Control Preventing Local Boiling
A control unit adjusts circulation flow rate to maintain engine outlet water temperature near target levels.
- Motor Vehicle Engine Cooling Circuit Cylinder Head Design
Upper and lower water chambers in the cylinder head reduce pressure drops while improving cooling efficiency around combustion chambers.
- Asymmetric Air Supply Manifold for Compact Engine Width
An asymmetric air supply manifold reduces engine width by shortening its cross-section along the row direction.
- Piston Cooling Conduit via Gudgeon Pin Locking
Lockable gudgeon pins create closed conduits for cooling oil, reducing surface pressure and fatigue resistance in large diesel engines.
- Marine Fuel Module Cooling via External Sprayer
External cooling fluid sprayer targets the outer housing surface to lower fuel temperature, eliminating internal heat exchanger leakage risks.
- Water Jacket Diverter Curved Rail Flow Control
A water jacket diverter with a curved upper rail directs coolant flow to reduce hydraulic losses and improve cooling efficiency.
- Integrated Cooling Section for Hybrid Power Apparatus
An integrated cooling section divides inhaled fluid to cool a driving section and generator, reducing weight compared to multiple separate devices.
- Cylinder Cooling Apparatus with Integrated Intake Manifold Water Injection
An integrated water supply line in the intake manifold distributes coolant to individual cylinders, preventing wall wetting and improving combustion stability.
- Hybrid Vehicle Fuel Tank Cooling Circuit
Cooling circuit passes through fuel tank to reduce pressure from outgassing without reinforcements.
- Integrated Thermal Management Unit for Vehicle Powertrain Fluids
A thermal management unit integrates a transmission oil heater and cooler within a single cast housing to regulate fluid temperature.
