Abstract

Systems and methods are provided for thermal control using vascular channels. Vascular channels are incorporated in a network within a component. The component is a part of a manufactured environment configured for occupants. A fluid circuit is connected with the vascular channels and circulates a fluid through the component to alter a thermal state of the component.

First claim

What is claimed is:

1. A thermal control system for a vehicle comprising:
a component comprising an interior panel of the vehicle, wherein the component defines an interior part of a cabin of the vehicle that has an inner layer comprising a class A appearance surface visible when the component is assembled in the vehicle;
vascular channels incorporated in a network within the component, wherein the vascular channels are open to the inner layer;
a fluid circuit connected with the vascular channels and configured to circulate a fluid through the component;
wherein the fluid alters a thermal state of the component by direct contact with the inner layer so that the component changes a heat load within the cabin.

2. The thermal control system of claim 1 wherein the component is an interior panel of the vehicle that defines a surrounding of at least a part of the cabin wherein the class A appearance surface is exposed to the cabin with an aesthetic appearance, and wherein the fluid circuit is configured to alter the thermal state by internally changing a temperature of the component.

3. The thermal control system of claim 1 comprising:
a heat exchanger, wherein the fluid circuit includes the heat exchanger; and
a heating-ventilation and air conditioning (HVAC) system configured to circulate a second fluid, wherein the second fluid is circulated through the heat exchanger.

4. The thermal control system of claim 1 wherein the component comprises a vehicle dashboard, wherein the packaging space and functional requirements are dictated the component as a vehicle dashboard, and wherein the vascular channels extend through the vehicle dashboard.

5. A thermal control system for a cabin of a vehicle comprising:
a component of the vehicle, wherein the component comprises a size and shape that defines an interior part of the cabin, wherein the component is configured to fit packaging space and functional requirements of an interior occupant facing panel of the vehicle, wherein the size, shape and functional requirements are unrelated to thermal control, the component including a layer comprising an appearance surface visible when the component is assembled in the vehicle, wherein the component includes a layer of material that defines the appearance surface;
a fluid circuit configured to circulate a fluid;
a vascular channel in the layer of material and connected with the fluid circuit, wherein the vascular channel is configured to channel the fluid through the component, wherein the component includes contours dictated by the packaging space and functional requirements, and wherein the vascular channels follow the contours; and
a heat exchanger carried by the vehicle, wherein the fluid circuit includes the heat exchanger;
wherein the fluid is configured to alter a thermal state of the component to increase or decrease a temperature of the cabin.

6. The thermal control system of claim 5 wherein the component comprises a vehicle windshield, wherein the vascular channels are defined by tubes of a transparent polymer and extend through the vehicle windshield.

7. The thermal control system of claim 1 comprising a second layer selective bonded to the inner layer at localized bonding areas, wherein the vascular channels are defined by the inner layer and the second layer and between the localized bonding areas.

8. The thermal control system of claim 1 wherein the vascular channels comprise tubes embedded in the component, wherein the tubes follow a shape and a contour of the component within constraints of the shape and features of the component including extending around openings of the component.

9. The thermal control system of claim 1 wherein the network comprises a manifold embedded in the component and connected with the vascular channels, wherein the manifold is embedded in the component.

10. The thermal control system of claim 1 wherein the component comprises a fiber material incorporated in a polymer matrix, and wherein the component defines openings wherein the vascular channels are arranged in a network in the component, the network including a number of channels running between a pair of manifolds positioned at edges of the component, wherein the manifolds that are laid out to avoid the openings.

11. The thermal control system of claim 1 comprising:
a first heat exchanger, wherein the fluid circuit includes the heat exchanger;
a heating-ventilation and air conditioning (HVAC) system configured to circulate air in the cabin, wherein the air is circulated through the first heat exchanger, a second heat exchanger and a third heat exchanger;
a coolant circuit of the HVAC system containing engine coolant and configured to circulate the engine coolant through the second heat exchanger;
an air conditioning system configured to circulate a refrigerant including through the third heat exchanger;
wherein the first heat exchanger is downstream from the second and third heat exchangers for air circulation.
