Liquid Cooling TRIZ Cases

Heat-expandable rubber components expand against coolant passage walls to prevent displacement and maintain intimate thermal contact.

A cooling system uses a motor-operated valve to bypass the thermostat and control coolant flow between an engine and heat exchangers.

Flat surface port arrangement simplifies six-face machining while internal routing maintains compact structural geometry.

A cylinder head uses a tapered recess to direct coolant flow between partial cooling chambers.

A cooling device adjusts coolant flow paths based on cylinder head temperature to manage heat transfer rates.

Continuous coolant circulation prevents intercooler overheating and nitrogen oxide emissions during automatic engine stop cycles.

A piston ring gap and cylinder bore recess bridge to allow controlled gas leakage between the combustion chamber and crankcase.

Positioning the water discharge passage below the oil cooler and forward of the crankshaft center axis utilizes gravity to drain cooling water when tilted.

A piston cooling nozzle integrates a tubular guide sleeve to center the valve and direct fluid flow.

A control apparatus calculates required cooling water flow rate based on intercooler efficiency and gas flow parameters.

A segmented liquid cooling circuit directs coolant flow to engine heads or blocks using independent pumps and valves.

Separate cooling water passages in a twin entry turbocharger turbine housing maintain lower temperatures in specific scroll chambers to reduce thermal stress.

Segmented showerhead apertures spray cooling oil as multiple jets to distribute fluid uniformly, reducing hot spots without increasing pump energy expenditure.

A single circulation circuit with multiple pumps and switching valves manages heat medium flow between vehicle components.

Segmented cooling circuits and dynamic valves route heated coolant from an integrated exhaust manifold to maintain optimal engine temperatures under high loads.

Preheating the thermostat via controlled heater power eliminates wax response delays and prevents abnormal temperature rises during abrupt thermal load changes.

Cooling fan speed adapts to engine output mode, reducing fuel consumption and noise while maintaining radiator performance.

Dynamic rotary shutter and flaps modulate engine compartment airflow area, reducing vehicle drag at high speeds while maintaining radiator cooling capacity.

A monolithic opposed-piston cylinder block uses a 3D printed casting core to integrate coolant paths and turbulators directly into the structure.

A thermal management system uses an ECU to adjust a grille shutter and flow rate valve based on cooling water temperature.

Asymmetric cooling water passage design in boat transmission cases reduces forward expansion while maintaining thermal performance.
