Abstract
An air conditioning system for automobile having a heater core capable of heating the interior in good efficiency is to be provided. Such a heater core is supplied with the coolant having bubbles removed, and thereby the efficiency of heat exchange is enhanced and the noise is reduced. On the internal combustion engine is mounted a water outlet (bubble separating means)having a receiving chamberthat the coolant after cooling the engine flows in. In the downstream position of the chamberis formed a communicating portionof narrowed sectional area and a feeding chamberof increased sectional area in turn. The flowing velocity of the coolant is increased in the communicating portionand decreased in the feeding chamberand thereby it is possible to make bubbles in the coolant float up and separate out. As a result, the coolant without bubbles may be fed to the heater corethrough a feeding portion
