Embodiment Construction

[0052] Figure 1A An air circulation duct of a car is shown. This duct comprises a housing 2 delimiting a ventilation channel 3 for the air to be heated to circulate. The air passing through the air duct has to pass through the heating openings and defogging / defrosting openings 4 and 5 before being dispersed into the cabin by mixing and distributing vanes 6 .

[0053] The air flow in the air duct 3 is generated by a fan 7 or a pulseur using the external air flow or the recirculation air flow generated in the cabin. Air reheating, if necessary, can be achieved by means of a heat exchanger 8 utilizing engine coolant and an electric heating device 8'. The heat exchanger 8 is installed in the ventilation channel 3 upstream of the heating device 8'. Another option is that the air reheating can only be realized by a single electric heating device 8'.

[0054] The electric heating device can occupy the entire cross-section of the air duct 3 . Alternatively, it can occupy a part o...

Abstract

The device has a case (15) circulated with air to be heated and delimiting a heat space that comprises of electrical heating modules (14). Each heating module has two metallic ribbons and resistive units with positive temperature coefficient. The case has supply compartments (20) for housing supply modules (200). The supply compartments constitute an active zone in the delimited heat space. - Independent claims are also included for the following: - (a) a heating and conditioning apparatus including a heating device for motor vehicle - (b) a method of mounting a heating device.

Description

technical field [0001] The invention relates to an air heating and heating device especially suitable for automobiles. Background technique [0002] In the present embodiment, air reheating and also defogging or defrosting processes in a motor vehicle compartment is effected by a heat exchange between air flow and engine coolant in air reheating circuit ducts. However, when the car is started, the heat transferred by the engine coolant may appear to be insufficient for a period of time to ensure rapid and efficient heating of the cabin. [0003] In other embodiments, an electric heating device can also be installed on the airflow duct leading to the compartment, so that the airflow can flow to the lower air outlet of the heat exchanger immediately. [0004] The heating is only active temporarily until the heat exchanger is able to perform the task of heating the air on its own. [0005] Such a heating system usually includes resistive elements of the positive temperature c...
