US 2002/0173264 A1 · Rear ventilation system for vehicle

Abstract

A rear ventilation system for a vehicle includes an air intake pump having a blower disposed within the housing to generate a forced flow of air into a thermal control. The thermal control includes a set of passages which direct air toward a heating and cooling core. The heating and cooling core includes a plurality of thermoelectric element units in communication with a direct current (DC) power supply disposed between a pair of heat exchangers. The plurality of thermoelectric element units absorb or generate heat employing the Peltier effect. The tempered air is delivered to at least one duct extending from the thermal control into the interior of the rear portion of the passenger compartment. A vent outlet in communication with the at least one duct extends into the rear passenger compartment to distribute air from the rear ventilation system.

Dependent claims

A rear ventilation system for a vehicle, the ventilation system comprising:

an air pump disposed in a trunk of the vehicle, the air intake pump having an air intake passage and a pump housing including a blower mounted within a cavity of the housing to generate a forced air flow through an air outlet;
a thermal control in communication with the air outlet of the air intake pump via an air inlet portion connected to the air outlet of the intake pump, the thermal control including at least one passage that receives the forced air flow from the blower, and an outlet passage;
and
a heating and cooling core disposed within the thermal control conditioning the forced air flow from the air intake pump, the heating and cooling core including at least two heat exchangers and a plurality of thermoelectric element units disposed between the heat exchangers, wherein the plurality of thermoelectric element units condition the air based on polarity of current flowing through the elements.
