Air conditioning system having cylindrical heat exchangers

1. An air conditioning system comprising:

an evaporator having a cylindrical body and defining a cavity;

a heater core having a cylindrical body and positioned within the cavity of the evaporator, wherein the evaporator and the heater core are coaxially positioned with each other about a center axis; and

a motor coupled to the heater core, wherein the motor rotates the heater core about the center axis.

2. The air conditioning system of claim 1 wherein the heater core includes multiple tubes and scroll shaped fins attached to an outer surface of the tubes.

3. The air conditioning system of claim 2 wherein the heater core is fluidly coupled to an air duct and draws in air from the air duct by way of the scroll shaped fins.

4. The air conditioning system of claim 1 further comprising:

a climate control module controlling the motor to adjust a rotational speed of the heater core.

5. The air conditioning system of claim 1 further comprising:

a first valve controlling flow of a first fluid to the evaporator, wherein the evaporator transfers heat from air flowing through the evaporator to the first fluid; and

a second valve controlling flow of a second fluid to the heater core, wherein the heater core transfers heat from the second fluid to air flowing through the heater core.

6. The air conditioning system of claim 1 further comprising:

a climate control module controlling flow of air through the heater core and the evaporator by controlling a rotational speed of the heater core by way of the motor.

7. The air conditioning system of claim 1 wherein the heater core includes an inlet conduit and an outlet conduit that partially extend along the center axis.

8. The air conditioning system of claim 1 wherein the heater core includes an inlet conduit and an outlet conduit configured to attach to an inlet hose and an outlet hose along the center axis, respectively.

9. An air conditioning system for a vehicle comprising:

an evaporator having a cylindrical body and defining a cavity;

a heater core having a cylindrical body and positioned within the cavity of the evaporator and defining a bore, wherein the evaporator and the heater core are coaxially positioned with each other about a center axis, and the heater core draws in air through the bore and directs the air outward toward the evaporator;

a motor operable for rotating the heater core about the center axis; and

a climate control module controlling a rotational movement outputted by the motor such that the climate control modules controls a rotational speed of the heater core by way of the motor, wherein the climate control module regulates air flow through the heater core and the evaporator via the motor.

10. The air conditioning system of claim 9 wherein the heater core is a heat exchanger that includes scroll shaped fins to draw in air through the bore as the heater core rotates.

11. The air conditioning system of claim 9 wherein the heater core is fluidly coupled to an air duct such that air flows through the air duct to the bore and outward toward the evaporator as the heater core rotates.

12. The air conditioning system of claim 9 further comprising;

a first valve controlling flow of a first fluid to the evaporator, wherein the evaporator transfers heat from air flowing through the evaporator to the first fluid; and

a second valve controlling flow of a second fluid to the heater core, wherein the heater core is a heat exchanger that transfers heat from the second fluid to air flowing from the bore through the heater core.

13. The air conditioning system of claim 12 wherein:

the climate control module controls the second valve in a heating mode and a cooling mode,

in the heating mode, an amount of the second fluid flowing to the heater core is greater than an amount of the first fluid flowing to the evaporator, and

in the cooling mode, the amount of the first fluid flowing to the evaporator is greater than the amount of the second fluid flowing to the heater core.
