Um einen Latentwärmespeicher (3) in einem Fahrzeug möglichst platzsparend und an einem gegen unfallbedingte Verformungen gesicherten Platz unterzubringen, wird erfindungsgemäss vorgeschlagen, den Latentwärmespeicher (3) in der Fahrgastzelle im Bereich des Fussraumes des Beifahrers einzubauen.
Abstract:
Thermomechanical regulating valve comprising a valve housing (4) provided with a first and second fluid inlet (10; 12) and a fluid outlet (14), with a chamber (6) which is connected to the inlets and outlet, in which chamber a valve closing body (8) is displaceably arranged for regulating the connection between the inlets and outlet. For comparing the temperatures of the fluid flows fed to the chamber (6) via the inlets, a temperature sensing adjusting device (16; 18) is inserted in each inlet, with a motion transmitting element (20; 22) articulated to the valve closing body, the movement of which elements, caused by the respective adjusting devices, gives rise to displacement and rotation of the valve closing body in the chamber to a position in contact with a seat, in which position the respective inlet is closed.
Abstract:
An internal combustion engine has a cooling system with a closed coolant circuit which comprises coolant passages in the cylinder head (22), the block (20) of the engine, a radiator (26) connected in parallel with the engine, a circulation pump (10) for circulating the coolant around the engine and the radiator, and a reservoir (30) connected in parallel with the engine and disposed below the level of the cylinder head (22). The coolant is transferred between the reservoir (30) and the engine by gravity and by the pressure head of the circulation pump (10). The cooling system is only partially filled with coolant so that the coolant from the cylinder head (22) is drained to the reservoir (30) by the action of gravity when the engine is at a standstill while leaving coolant in the cylinder block (20) and the circulation pump (10). The cylinder head (22) is gradually refilled with coolant from the reservoir (30) after engine startup as a pressure head is built up by the circulation pump (10).
Abstract:
In a heat accumulator, in particular a latent heat accumulator for motor vehicle heating systems which store waste engine heat, inlet and outlet pipes (12, 14) traverse an insulating space (30, 30a) which serves as a heat insulator located between a heat accumulator housing (10) surrounding the accumulator core and an outer heat accumulator housing (28). Inside the insulating space (30, 30a), these pipes have an at least approximately vertical section (26) the upper end of which is connected to the internal heat accumulator housing (10) and the vertical length of which, derived from the temperature gradient between the accumulator core and the surroundings and from the thermal conductivity of the transmission medium conveyed in the pipes, corresponds to the vertical extension of a barrier layer which provides the required degree of insulation. This barrier layer extends between the upper end of the approximately vertical section of the pipes, which is connected to the accumulator core and is therefore hotter, and the lower end which is in communication with the surroundings and is therefore cooler.
