Thermally conditioned container for a vehicle
View Patent ↗A thermo-electric device is disposed in series with the HVAC module for heating and cooling air T a from the HVAC module for delivery to seat passages of a seat assembly and/or to a thermal container. The thermoelectric device includes a thermoelectric module, a heat exchanger having cold and hot sides, ductwork, a divider that sends variable air flow to the cold or hot sides of the thermoelectric module, and thermal insulation between the cold and hot sides downstream of the heat exchanger. The fan of the HVAC module is the sole motivation for moving the conditioned air T a originating from the central HVAC module through the thermoelectric device and to the seat assembly and/or to a thermal container.
1. An automotive vehicle comprising;
a body defining a passenger cabin,
a thermal container defining a compartment disposed in said passenger cabin and for thermally conditioning articles in said compartment with air,
at least one cabin vent in said vehicle for conveying the air into said passenger cabin, an HVAC module for supplying heating and cooling air,
ductwork for conveying said heating and cooling air from said HVAC module to said cabin vent and to said thermal container, an auxiliary air-conditioning device in said ductwork for heating and cooling the air from said HVAC module for delivery to said compartment of said thermal container, and a seat assembly disposed in said passenger cabin and having seat passages for thermally conditioning a seat occupant with the air, wherein said auxiliary air-conditioning device includes a seat side and a cabin side and a heat exchanger disposed between said seat side and cabin side for transferring heat therebetween, and said ductwork includes a seat duct for conveying the air from said seat side to said seat passages and a cabin duct for conveying air from said cabin side to said cabin vent.
2. An automotive vehicle comprising;
a body defining a passenger cabin,
a comfort device disposed in said passenger cabin and for thermally conditioning the comfort device with air,
at least one cabin vent in said vehicle for conveying air into said passenger cabin, an HVAC module for supplying heating and cooling air,
ductwork for conveying said heating and cooling air from said HVAC module to said cabin vent and to said comfort device,
an auxiliary air-conditioning device in said ductwork for heating and cooling the air from said HVAC module for delivery to said comfort device, and a seat assembly disposed in said passenger cabin and having seat passages for thermally conditioning a seat occupant with the air, wherein said auxiliary air-conditioning device includes a seat side and a cabin side and a heat exchanger disposed between said seat side and cabin side for transferring heat therebetween, and said ductwork includes a seat duct for conveying the air from said seat side to said seat passages and a cabin duct for conveying the air from said cabin side to said cabin vent.
3. An auxiliary air-conditioning device as set forth in claim 2 wherein said auxiliary air-conditioning device comprises a thermo-electric device for receiving electrical power from the electrical system of the vehicle.
4. An auxiliary air-conditioning device as set forth in claim 2 wherein said comfort device includes a thermal container.
