Definitions

  • the invention relates to a latent heat store for the cooling water circuit of a motor vehicle internal combustion engine with an interior containing a storage medium that changes from a solid to a liquid state and vice versa and changes its volume.
  • the object of the invention is to detect the state of charge of the latent heat store in the simplest possible way and to control the devices belonging to the latent heat store, in particular a pump, according to the state of charge.
  • a sensor, switch or valve is connected to or in the interior of the latent heat accumulator, which sensor is controlled / influenced by the volume changes.
  • cooling water circuit can be controlled by the sensor, the switch or the valve.
  • a static latent heat store with, in particular a salt hydrate as a meltable storage medium has a receiving space (interior) for the storage medium which is traversed by channels, in particular pipes, which form heat exchange surfaces and through which cooling water flows.
  • a sensor, switch or valve In the receiving space (interior) of the storage medium, a sensor, switch or valve is fastened inside and / or on the wall of the space, which is controlled / influenced by the pressure in the interior.
  • the Pressure changes due to changes in volume of the storage medium during the change from the liquid to the solid state and vice versa are used.
  • the sensor, switch or valve are set in such a way that registration / switching always takes place when the state of aggregation changes.
  • the respective state of aggregation thus directly controls the cooling circuit precisely insofar as it influences the latent heat storage or the latent heat storage the cooling circuit.
  • the valve is preferably used directly in the cooling water circuit or in a bypass or a secondary line of the cooling water circuit and, if a sensor or switch is selected, the cooling water circuit, in particular a pump in the cooling water circuit or in the bypass / in the secondary line, is controlled directly or via an electronic control device.

Abstract

L'invention concerne un régulateur thermique à changement d'état pour le circuit d'eau de refroidissement d'un moteur à combustion interne d'automobile, comportant un espace intérieur qui contient un agent d'accumulation qui passe d'un état solide à un état liquide et inversement et change à cette occasion de volume. Un détecteur, un interrupteur ou un clapet est raccordé sur ou dans l'espace intérieur du régulateur thermique à changement d'état, l'un ou l'autre étant piloté par les modifications de volume ou en subissant l'influence.
