Abstract

An apparatus to reverse the direction of fluid flow is provided. The apparatus can include a first channel and a second channel. The first channel and second channel can define a first position to provide a first fluid flow direction via the first channel and the second channel. The apparatus can include a third channel and a fourth channel. The third channel and the fourth channel can define a second position to provide a second fluid flow direction via the third channel and the fourth channel. The apparatus can be configured to actuate from the first position to the second position to reverse flow direction from the first fluid flow direction to the second fluid flow direction.

First claim

What is claimed is:

1 . An apparatus, comprising:
at least four separate channels having at least eight separate openings including:
a first channel having a first opening and a second opening and a second channel having a third opening and a fourth opening, the first channel and the second channel in a first position to provide a first fluid flow direction via the first channel and the second channel; and
a third channel having a fifth opening and a sixth opening and a fourth channel having a seventh opening and an eighth opening, the third channel and the fourth channel in a second position to provide a second fluid flow direction via the third channel and the fourth channel;
a first face having the first opening of the first channel, the third opening of the second channel, the fifth opening of the third channel, and the seventh opening of the fourth channel; a second face separate from the first face, the second face having the second opening of the first channel, the fourth opening of the second channel, the sixth opening of the third channel, and the eighth opening of the fourth channel; and the apparatus configured to actuate from the first position to the second position to reverse flow direction from the first fluid flow direction to the second fluid flow direction.

2 . The apparatus of claim 1 , wherein the first channel and third channel are ingress channels and wherein the second channel and fourth channel are egress channels.

3 . The apparatus of claim 1 , comprising:
the apparatus including a valve configured to actuate from the first position to the second position to reverse the flow direction in a thermal component from the first fluid flow direction to the second fluid flow direction.

4 . The apparatus of claim 1 , comprising:
the first channel and the fourth channel to couple with a first opening of a thermal component; and the second channel and the third channel to couple with a second opening of the thermal component, the first opening of the thermal component and the second opening of the thermal component in communication via a cooling line defined by the thermal component.

5 . The apparatus of claim 1 , comprising:
the first channel configured to provide fluid to a first opening of a thermal component with the apparatus in the first position, the second channel configured to receive fluid from a second opening of the thermal component with the apparatus in the first position; and the third channel configured to provide fluid to the second opening of the thermal component with the apparatus in the second position, and the fourth channel configured to receive fluid from the first opening of the thermal component with the apparatus in the second position.

6 . The apparatus of claim 1 , comprising:
the first channel and the fourth channel configured to couple with a first opening of a thermal component, the first opening of the thermal component configured as an inlet with the apparatus in the first position, and the first opening of the thermal component configured as an outlet with the apparatus in the second position; and the second channel and the third channel configured to couple with a second opening of the thermal component, the second opening of the thermal component configured as an outlet with the apparatus in the first position, and the second opening of the thermal component configured as an inlet with the apparatus in the second position.

7 . The apparatus of claim 1 , comprising:
the first channel configured to provide fluid in the first fluid flow direction to a first opening of a thermal component with the apparatus in the first position; the second channel configured to receive fluid in the first fluid flow direction from a second opening of the thermal component with the apparatus in the first position; the third channel configured to provide fluid in the second fluid flow direction to the second opening of the thermal component with the apparatus in the second position; the fourth channel configured to receive fluid in the second fluid flow direction from the first opening of the thermal component with the apparatus in the second position; and the first opening and the second opening of the thermal component are in communication via a cooling line defined by the thermal component, the first fluid flow direction in the cooling line configured to be opposite the second fluid flow direction in the cooling line.

8 . The apparatus of claim 1 , comprising:
the apparatus including a valve to actuate from the first position to the second position at a threshold temperature of an at least one battery module.

9 . The apparatus of claim 1 , comprising:
the apparatus includes a valve to actuate from the second position to the first position at a threshold temperature of an at least one battery module.

10 . The apparatus of claim 1 , comprising:
the apparatus includes a valve to actuate from the first position to the second position via a motor and from the second position to the first position via the motor.

11 . The apparatus of claim 1 , comprising:
the first channel and the fourth channel configured to couple with a first opening of a thermal component via a first connector; and the second channel and the third channel configured to couple with a second opening of the thermal component via a second connector.

12 . The apparatus of claim 1 , comprising:
the first channel and the fourth channel configured to couple with a first opening of a thermal component via a first connector; and the second channel and the third channel configured to couple with a second opening of the thermal component via a second connector, the first channel, the second channel, the third channel, and the fourth channel each comprising channel port seal members in contact with the first connector and the second connector.

13 . The apparatus of claim 1 , comprising:
the first channel and the fourth channel configured to couple with a first connector tube; and the second channel and the third channel configured to couple with a second connector tube.

14 . The apparatus of claim 1 , comprising:
the apparatus positioned between a heat exchanger and a thermal component, the heat exchanger configured to provide fluid to the first channel and the third channel, the first channel and the third channel configured to provide fluid to the thermal component, the thermal component configured to provide fluid to the second channel and the fourth channel.

15 . A system, comprising:
a first submodule having a bottom surface; a second submodule having a top surface; a thermal component positioned between the top surface of the second submodule and the bottom surface of the first submodule, the thermal component having a cooling line, the thermal component defining a first opening and a second opening, the first opening and the second opening connected by the cooling line; and a valve configured to actuate from a first position to a second position, the valve comprising at least four separate channels having at least eight separate openings including:
a first ingress channel having a first opening and a second opening, the first ingress channel in communication with the first opening of the thermal component with the valve in the first position;
a first egress channel having a third opening and a fourth opening, the first egress channel in communication with the second opening of the thermal component with the valve in the first position;
