Coolant-water mixtures are used in vehicles to dissipate heat from diverse heat sources and supply it to other points, such as the interior heating system. Excess heat is conducted to the vehicle radiator, which is located in the front end. Via the radiator, through which the air flow passes, the cooled coolant is returned to the engine system.
The coolant is transported between the individual units and components by means of pipes which, depending on the application requirements, can be made of various material mixtures. Pipe parts are usually made of aluminium. For hotter applications, stainless steel pipes are used, and for lower temperatures, plastic pipes. Tolerance and movement compensation of the components is ensured either by hose components or by the geometry of the components. We also use different materials for the hoses (EPDM, VMQ, PTFE), depending on the pressure and temperature application. In addition, the components can be protected from heat radiation by heat protection hoses, heat protection mats or heat protection sheets, which are applied to the lines.
