Abstract

A temperature control equipment ( 3 ) for a vehicle, in particular an electric vehicle, enables an aerothermic adjustment of an airflow to be distributed in a passenger compartment (H) of the vehicle. The temperature control equipment ( 3 ) includes at least one heat treatment module ( 8 ), capable of heat-treating the airflow, and a distribution module ( 9 ), capable of distributing the airflow to the passenger compartment (H). The heat treatment module ( 8 ) comprises a single means ( 21 ) for heating the airflow to be distributed in the passenger compartment (H), which consists of an electric radiator ( 21 ).

First claim

The invention claimed is:

1. A thermal conditioning installation for allowing aerothermal adjustment of an airflow to be diffused into a passenger compartment (H) of a vehicle including a separating wall having a first side and a second side opposite the first side with a through-passage extending through the first side and the second side, the thermal conditioning installation comprising:
at least one heat treatment module configured to thermally treat the airflow and configured to mount to the first side of the separating wall;
a distribution module configured to distribute the airflow in the passenger compartment (H) and configured to mount to the second side of the separating wall;
wherein the heat treatment module comprises an electric radiator; and
a bypass duct comprising a downstream opening that opens into the distribution module and downstream of the electric radiator and an upstream opening disposed upstream of the electric radiator with the bypass duct comprising two regulating members for calibrating the amount of the airflow circulating in the bypass duct;
wherein the heat treatment module and the distribution module are separate assemblies and configured to be in aerial communication when mounted to the separating wall such that the airflow which is aerothermally adjusted by the heat treatment module circulates in the distribution module, through the through-passage, before being diffused into the passenger compartment (H).

2. The thermal conditioning installation of claim 1 , wherein a first regulating member is disposed at the downstream opening and a second regulating member is disposed at the upstream opening of the bypass duct, respectively.

3. The thermal conditioning installation of claim 1 , wherein the bypass duct extends in the heat treatment module and in the distribution module.

4. The thermal conditioning installation of claim 1 , wherein the heat treatment module comprises a heat treatment housing in which the electric radiator is housed.

5. The thermal conditioning installation of claim 4 , wherein the heat treatment housing comprises at least one engine fan configured to force the circulation of the airflow in the thermal conditioning installation.

6. The thermal conditioning installation of claim 5 , wherein the engine fan is located downstream of an inlet of the heat treatment module and upstream of both the electric radiator and the bypass duct.

7. The thermal conditioning installation of claim 1 , further comprising a footwell distribution canal, an aeration distribution canal, and a defrosting distribution canal for managing air flow.

8. The thermal condition installation of claim 1 , wherein the footwell distribution canal comprises a footwell flap, the aeration distribution canal comprises an aeration flap, and the defrosting distribution canal comprises a defrosting flap.

9. The thermal condition installation of claim 8 , wherein the downstream opening of the bypass duct opens into the aeration distribution canal.

10. The thermal conditioning installation of claim 1 , wherein the bypass duct is defined by a housing and an interior structure that is different than the two regulating members.

11. The thermal conditioning installation of claim 1 , further comprising at least one air distribution chamber arranged in the distribution module and disposed downstream of the electric radiator.

12. The thermal conditioning installation of claim 11 , wherein the distribution module comprises at least one footwell distribution canal and an aeration distribution canal, both disposed downstream of the air distribution chamber.

13. The thermal conditioning installation of claim 1 , wherein the electric radiator is the only heating means of the heat treatment module.

14. A vehicle comprising:
a separating wall having a first side facing an engine compartment and a second side opposite the first side and facing the passenger compartment (H) with the separating wall having a through- passage extending through the first side and the second side; and
a thermal conditioning installation comprising,
at least one heat treatment module configured to thermally treat an airflow and mounted to the first side of the separating wall,
a distribution module configured to distribute the airflow in the passenger compartment (H) of the vehicle and mounted to the second side of the separating wall, and
a bypass duct comprising a downstream opening that opens into the distribution module and downstream of the electric radiator and an upstream opening disposed upstream of the electric radiator with the bypass duct comprising two regulating members for calibrating the amount of the airflow circulating in the bypass duct,
wherein the heat treatment module comprises an electric radiator for heating the airflow intended to be diffused into the passenger compartment (H), and
wherein the heat treatment module and the distribution module are separate assemblies configured to be in aerial communication when mounted to the separating wall such that the airflow which is aerothermally adjusted by the heat treatment module circulates in the distribution module, through the through-passage, before being diffused into the passenger compartment (H).

15. The vehicle of claim 14 , wherein a first regulating member is disposed at the downstream opening and a second regulating member is disposed at the upstream opening of the bypass duct, respectively.

16. The vehicle of claim 14 , wherein the bypass duct extends in the heat treatment module and in the distribution module.

17. The vehicle of claim 14 , wherein the separating wall comprises a mating strip arranged around the through-passage and against which the thermal conditioning installation bears.

18. The vehicle of claim 17 , wherein the thermal conditioning installation comprises a means for securing the thermal conditioning installation to the separating wall.
