Abstract

Methods and apparatus for de-gasification of vehicle cooling system using a coolant bottle are disclosed. The coolant bottle may include a coolant entrance port configured to be in fluid communication with the vehicle cooling system, and a coolant egress port configured to be in fluid communication with the vehicle cooling system. The coolant egress port is directly connected to the vehicle cooling system. The coolant bottle may further include a plurality of baffle plates placed to divide an interior of the coolant bottle into a plurality of coolant channels. Each baffle plate may include a plurality of apertures configured to provide fluid communication between the plurality of coolant channels.

First claim

What is claimed is:

1. A method of de-gasifying a coolant fluid using a coolant bottle, the coolant bottle including at least a first opening and a second opening, the first opening comprising a coolant entrance port located on a top of the coolant bottle, the second opening comprising a coolant egress port located at a bottom of the coolant bottle, the coolant bottle further comprising a plurality of baffle plates, the baffle plates positioned to divide an interior of the coolant bottle into a plurality of coolant channels, each of the plurality of baffle plates including a plurality of apertures configured to provide fluid communication between the plurality of coolant channels, the method comprising:
feeding a coolant fluid to be degassed through the coolant entrance port into a top portion of the coolant bottle;
substantially degassing the coolant fluid while inside the coolant bottle; and
directing the degassed coolant fluid to exit the coolant bottle and directly reenter a vehicle cooling system through the coolant egress port that is directly connected to the vehicle cooling system;
wherein the plurality of baffle plates comprises a first set of baffle plates and a second set of baffle plates, the first set of baffle plates each including a plurality of first apertures in a first configuration, wherein each aperture in the first configuration is located at an equidistance from adjacent apertures and edges of the respective baffle plate, and the second set of baffle plates each including a plurality of second apertures in a second configuration,
wherein the first apertures do not align with any of the second apertures;
wherein the first set of baffle plates are placed in parallel with the second set of baffle plates; and
wherein substantially degassing the coolant fluid while inside the coolant bottle further comprises directing the coolant fluid to flow in a nonlinear fashion by a differentiation in horizontal locations of first and second apertures.

2. The method of claim 1 ,
wherein the coolant bottle further includes a first set of baffle plates each including a plurality of first apertures in a first configuration;
a second set of baffle plates each including a plurality of second apertures in a second configuration, wherein the first apertures do not align with any of the second apertures when the first set of baffle plates are placed in parallel with the second set of baffle plates,
the method further comprising: directing the coolant fluid to flow across the coolant channels through the first apertures and second apertures.

3. The method of claim 1 , wherein each baffle plate is scored and pitted to create bubble nucleation sites.

4. The method of claim 1 , further comprising: opening a pressure relief valve located within a cap on the top of the coolant bottle at a pressure of about 1 atm.-5 atm.

5. The method of claim 1 , further comprising distributing wave energy flowing through the coolant bottle among the plurality of coolant channels and limiting turbulence in the coolant bottle.
