Abstract

A seat climate control system includes a seat body having a first body surface and a second body surface opposite and spaced apart from the first body surface. The seat body defines an interior volume. The seat climate control system further includes at least one thermoelectric module at least partially disposed within the interior volume of the seat body. The thermoelectric module is configured to facilitate heat transfer upon receipt of electrical energy. The seat climate control system further includes at least one thermally conductive member disposed along the first body surface. The thermally conductive member is thermally coupled to the thermoelectric module. The thermally conductive member is configured to transfer heat between the thermoelectric module and a surface in contact with the thermally conductive member.

First claim

The invention claimed is:

1. A seat climate control system, comprising:
a seat body defining an inlet opening, at least one outlet opening, and at least one fluid conduit establishing fluid communication between the inlet opening and the at least one outlet opening, the seat body including a first body surface and a second body surface opposite and spaced apart from the first body surface, wherein the seat body defines an interior volume;
at least one thermoelectric module at least partially disposed within the interior volume, the at least one thermoelectric module being configured to facilitate heat transfer upon receipt of electrical energy;
at least one thermally conductive member disposed along the first body surface, the at least one thermally conductive member being thermally coupled to the at least one thermoelectric module;
at least one fan disposed in the at least one fluid conduit, the at least one fan being configured to direct flow of gas from the inlet opening to the at least one outlet opening; and
wherein the at least one thermally conductive member is configured to transfer heat between the at least one thermoelectric module and a surface in direct contact with the at least one thermally conductive member.

2. The seat climate control system of claim 1 , wherein the at least one thermoelectric module is a Peltier module.

3. The seat climate control system of claim 1 , wherein the seat body is configured as a seat back.

4. The seat climate control system of claim 1 , wherein the seat body is configured to be coupled to a vehicle seat.

5. The seat climate control system of claim 1 , further comprising at least one heat sink configured to dissipate heat, the at least one heat sink being thermally coupled to the at least one thermoelectric module.

6. The seat climate control system of claim 5 , wherein the at least one fan is coupled to the at least one heat sink.

7. A vehicle, comprising:
a seat body defining an inlet opening, at least one outlet opening, at least one fluid conduit establishing fluid communication between the inlet opening and the at least one outlet opening, the seat body including a first body surface and a second body surface opposite and spaced apart from the first body surface, wherein the seat body defines an interior volume;
a power source configured to supply electrical energy;
at least one thermoelectric module electrically connected to the power source, the at least one thermoelectric module being at least partially disposed within the interior volume, the at least one thermoelectric module being configured to facilitate heat transfer upon receipt of electrical energy from the power source;
at least one thermally conductive plate exposed along the first body surface, the at least one thermally conductive plate being thermally coupled to the at least one thermoelectric module;
at least one fan disposed in the at least one fluid conduit, the at least one fan being configured to direct flow of gas from the inlet opening to the at least one outlet opening;
at least one heat sink attached to the at least one fan, the at least one heat sink being configured to dissipate heat; and
wherein the at least one thermoelectric module is configured to transfer heat between a surface in contact with the at least one thermally conductive plate and the at least one thermoelectric module.

8. The vehicle of claim 7 , wherein the at least one thermoelectric module is a Peltier module.

9. The vehicle of claim 7 , wherein the seat body includes a third body surface and a fourth body surface opposite and spaced apart from the third body surface, the third body surface being disposed between the first and second body surfaces, and the at least one outlet opening is disposed along the third body surface and the fourth body surface.

10. The vehicle of claim 9 , wherein the seat body includes a fifth body surface and a sixth body surface opposite and spaced apart from the fifth body surface, the fifth body surface being disposed between the first body surface and the second body surface, and the inlet opening being disposed at the sixth body surface.

11. The vehicle of claim 10 , wherein the first body surface, the second body surface, the third body surface, the fourth body surface, the fifth body surface, and the sixth body surface define an entire outer perimeter of the seat body.

12. The vehicle of claim 11 , wherein the seat body is shaped as a seat back.

13. The vehicle of claim 12 , wherein the vehicle includes a vehicle seat, and the seat body is not an integral part of the vehicle seat.

14. The vehicle of claim 13 , wherein the seat body is configured to be coupled to the vehicle seat.

15. The vehicle of claim 7 , wherein the at least one fan is a first fan, and the vehicle further comprises a second fan that is not attached to the at least one heat sink.

16. The vehicle of claim 7 , further comprising a pressure switch disposed along the front body surface and being configured to detect pressure exerted against the front body surface, the pressure switch being electrically connected between the at least one thermoelectric module and the power source in order to establish an electrical connection between the power source and the at least one thermoelectric module when pressure is exerted against the front body surface.

17. The vehicle of claim 7 , wherein the seat body is elongated along a seat axis, and the at least one fluid conduit includes is a main conduit elongated along the seat axis, the main conduit being in direct fluid communication with the inlet opening.

18. The vehicle of claim 17 , further comprising a plurality of branch conduits perpendicularly angled relative to the main conduit, each of the branch conduits being disposed in fluid communication with the main conduit.
