Abstract

A multi-port thermal module which includes a central housing, a plurality of flow cavities integrally formed as part of the central housing, at least one inner housing connected to a first side of the central housing, a first plurality of inner flow channels integrally formed as part of the first inner housing, each of the first plurality of inner flow channels in fluid communication with at least one of the flow cavities, and a first outer housing connected to the first inner housing. A portion of each of a first plurality of flow channels is integrally formed as part of the first inner housing, and another portion of each of the first plurality of flow channels is integrally formed as part of the first outer housing. A rotor located in the central housing is rotated to various orientations to direct fluid between the plurality of flow cavities.

First claim

What is claimed is:

1. An apparatus, comprising:
a multi-port thermal module, including:
a central housing;
a plurality of flow cavities integrally formed as part of the central housing;
a first inner housing portion connected to a first side of the central housing;
at least one inner flow channel integrally formed as part of the first inner housing portion and in fluid communication with at least one of the plurality of flow cavities;
at least one valve located in the central housing;
a first outer housing portion connected to the first inner housing portion;
at least one flow channel, a portion of the first inner housing portion being part of the at least one flow channel, and a portion of the first outer housing portion being part of the at least one flow channel such that the at least one flow channel is in fluid communication with the at least one inner flow channel;
wherein the at least one valve selectively directs fluid between two or more of the plurality of flow cavities.

2. The apparatus of claim 1 , further comprising a cavity integrally formed as part of the central housing and in fluid communication with one or more of the plurality of flow cavities, wherein the at least one valve is disposed in the cavity.

3. The apparatus of claim 1 , further comprising:
a pump housing connected to at least one of the central housing, the first inner housing portion, or the first outer housing portion;
at least one pump mounted to the pump housing;
at first pump housing channel integrally formed as part of the pump housing and in fluid communication with the at least one pump and at least one of the at least one channel flow channel or the at least one inner flow channel; and
a second pump housing channel integrally formed as part of the pump housing and in fluid communication with the at least one pump and the at least one valve;
wherein the at least one pump transfers fluid from either of the at least one flow channel or the at least one inner flow channel, through the first pump housing channel, through the second pump housing channel, and to the at least one valve.

4. The apparatus of claim 1 , further comprising:
a second inner housing portion connected to the central housing;
at least one inner flow channel integrally formed as part of the second housing portion;
wherein the at least one inner flow channel integrally formed as part of the second housing portion is in fluid communication with at least one of the plurality of flow cavities.

5. The apparatus of claim 4 , wherein the at least one inner flow channel integrally formed as part of the first inner housing portion and the at least one inner flow channel integrally formed as part of the second inner housing portion are in fluid communication with the same one of the plurality of flow cavities.

6. The apparatus of claim 4 , further comprising:
a second outer housing portion connected to the second inner housing portion; and
at least one flow channel, a portion of the second inner housing portion being part of the at least one channel, and a portion of the second outer housing portion being part of the at least one channel;
wherein the at least one flow channel is in fluid communication with the at least one inner flow channel integrally formed as part of the second inner housing portion.

7. A multi-port thermal module, comprising:
a central housing;
a plurality of flow cavities integrally formed as part of the central housing;
a first inner housing portion connected to a first side of the central housing;
a first plurality of inner flow channels integrally formed as part of the first inner housing portion, each of the first plurality of inner flow channels in fluid communication with at least one of the plurality of flow cavities;
a first outer housing portion connected to the first inner housing portion;
a first plurality of flow channels, a portion of each of the first plurality of flow channels being integrally formed as part of the first inner housing, and another portion of each of the first plurality of flow channels being integrally formed as part of the first outer housing;
at least one valve disposed in the central housing;
at least one pump in fluid communication with and operable for transferring fluid from one of the first plurality of flow channels to the at least one valve; and
at least one actuator mounted to the central housing and connected to the at least one valve, and the at least one actuator changes the orientation of the at least one valve to direct fluid between two or more of the plurality of flow cavities, or direct fluid from the valve to one or more of the plurality of flow cavities;
wherein each of the first plurality of flow channels is in fluid communication with at least one of the first plurality of inner flow channels.

8. The multi-port thermal module of claim 7 , further comprising:
the at least one valve further comprising a plurality of valves, each of the plurality of valves disposed in a corresponding cavity of the central housing; and
the at least one actuator further comprising a plurality of actuators mounted to the central housing and connected to a corresponding one of the plurality of valves;
wherein each of the plurality of actuators changes the orientation of a corresponding one of the plurality of valves to direct fluid between two or more of the plurality of flow cavities, or to direct fluid from a corresponding one of the plurality of valves to one or more of the plurality of flow cavities.

9. The multi-port thermal module of claim 8 , further comprising:
a pump housing connected to the first outer housing and the central housing; and
the at least one pump further comprising a plurality of pumps mounted to the pump housing;
wherein each of the plurality of pumps is operable for transferring fluid from one of the first plurality of flow channels to a corresponding one of the plurality of valves.

10. The multi-port thermal module of claim 7 , further comprising:
a second inner housing connected to a second side of the central housing; and
a second plurality of inner flow channels integrally formed as part of the second inner housing;
wherein each of the second plurality of inner flow channels is in fluid communication with at least one of the plurality of flow cavities.

11. The multi-port thermal module of claim 10 , further comprising:
a second outer housing connected to the second inner housing; and
a second plurality of flow channels, each of the second plurality of flow channels is in fluid communication with at least one of the second plurality of inner flow channels;
wherein a portion of each of the second plurality of flow channels is integrally formed as part of the second inner housing, and another portion of each of the second plurality of flow channels is integrally formed as part of the second outer housing.
