Abstract

Official abstract text for this publication.

The invention relates to a liquid heating device for an automobile that comprises two independent liquid flow paths ( 10 a, 10 b ) integrally formed in at least one part ( 1 a ) made of a heat-conducting material, each liquid flow path ( 10 a ) being capable of enabling a flow of liquid between a connection terminal defining an inlet and a connection terminal defining an outlet ( 12 a, 12 b ), each of the connection terminals being capable of sealingly receiving a liquid supply duct or tube, and a heating means ( 14 ) thermally coupled with said part ( 1 a ) and capable of heating said part ( 1 a ) so that the liquid flowing through said flow paths can absorb the heat of said part ( 1 a ). The invention advantageously enables the very flexible use thereof for one or more systems requiring heated liquid inside a single vehicle.

First claim

Opening claim text (preview).

The invention claimed is: 1. A liquid heating device for an automobile, comprising: two liquid flow paths integrally formed in at least one part made of a heat-conducting material, each liquid flow path being capable of enabling a flow of liquid between a connection terminal defining an inlet and a connection terminal defining an outlet, with each one of the connection terminals being capable of sealingly receiving a liquid supply duct or tube; and a heating means thermally coup…
