<p>The present invention relates to a heat exchanger device comprising a coil (120) having an inlet (122) and an outlet (124) for connection to a primary heat-transfer fluid circuit (200) and a tank (150) in which this coil (120) is placed, which tank (150) is filled with a secondary heat-transfer fluid and comprises an inlet (152) and an outlet (154) for connection to a secondary circuit (300), the coil (120) in which the primary heat-transfer fluid circulates housing a secondary coil (130) so as to form a solenoid exchanger having coaxial tubes, and one of the connections (152, 154) to the secondary circuit (300) being coupled directly to one of the ends (132, 134) of the secondary coil (130), whereas the other connection (154, 152) to the secondary circuit along with the second end (134, 132) of the secondary coil (130) open into the tank (150), such that the exchanges between the primary heat-transfer fluid and the secondary heat-transfer fluid in the solenoid exchanger having co-axial tubes are performed both in the form of forced convection inside the said exchanger and in the form of natural convection outside said exchanger, characterized in that the start (154) for the secondary fluid is coupled directly to one end of the secondary coil (130), whereas the return (152) for the secondary fluid opens freely into the tank (150).</p> |
