As the engine downsizing technology progresses, small displacements produce ever greater power. In addition, the trend toward increasingly more powerful engines subjects other engine components to higher loads. To lower fuel consumption, engines must operate close to the temperature limit of their materials. As a result, heating and cooling modules will gain a growing significance in the future.
Heat exchangers for heating and cooling modules usually have a stacking disk design and ensure the optimized thermal economy balance of lubricants in the engine and transmission. Heat exchangers allow the lubricant to heat rapidly, which in turn considerably reduces fuel consumption during cold starts. At high oil temperatures, heat exchangers prevent overheating and consequently premature ageing of the oil. They also enable longer service intervals. Current MAHLE heating and cooling modules can moreover assume channel guiding and temperature control functions as well as the filtration of the coolant flow. Optimized channel guidance and distribution of the coolant flow supply the heat exchangers for the engine and transmission as well as for fuel with coolant as required.
MAHLE's expertise in heating and cooling modules and also in the layout and design of the interfaces between heat exchanger and the adjoining system components, ensures that none of the components fail prematurely.
