Abstract

A vehicle heating system supplied with coolant from the engine and in the case of which there is a bypass connecting limbs of the heating circuit extending downstream from the engine and, respectively, upstream therefrom, is provided in the heating circuit with a heat storage means, which is arranged on the heating side separately from the bypass and preferably in series with the vehicle heating system.

Claims

1. A motor vehicle heating device comprising a heat exchanger adapted to be supplied with coolant from an engine, the engine including a desired predetermined amount of coolant representing all of the coolant in said engine, a heating circuit defining means for providing a flow of said predetermined amount of coolant, said heat circuit comprising outlet conduit means disposed upstream of said heat exchanger for providing passage of all of the predetermined amount of coolant to pass from the engine to the heat exchanger and a return conduit means disposed downstream of said heat exchanger for providing passage of all of the predetermined amount of coolant to pass from the heat exchanger back to the engine representing a full coolant cycle, a pair of bypass duct means connected to said outlet conduit means and return conduit means such that a portion of said predetermined amount of coolant may enter said bypass duct means bypassing said heat exchanger;

and a latent heat storage means coupled with one of said outlet or return conduit means and positioned in said outlet conduit means between said pair of bypass duct means such that during each full cycle all of the predetermined amount of coolant from the engine passes through said latent heat storage means transferring heat between said latent heat storage means and said coolant such that said latent heat storage means is charged and its charge dissipated only by transfer of heat between the coolant and latent heat storage means.

2. The motor vehicle heating device as claimed in claim 1 wherein the heat storage means is placed in series with the heat exchanger.
