Abstract

A deaeration device for deaerating coolant fluid flow in a recirculation cooling system, where the recirculation cooling system includes a cooling fluid reservoir adapted to receive the deaeration device submerged within cooling fluid therein, includes an elongated deaeration tube including a fluid outlet and a deaerating skimming shaped slot for skimming air bubbles and cooling fluid from cooling fluid flow flowing through the deaeration tube, and including a fluid inlet for allowing the same amount of fluid that is skimmed off and removed through the top fluid outlet to re-enter the deaeration tube to maintain mass balance in the cooling fluid flow.

Claims (18)

1. A deaeration device for deaerating coolant fluid flow in a recirculation cooling system, the recirculation cooling system including a cooling fluid reservoir adapted to receive the deaeration device submerged within cooling fluid therein, comprising: an elongated deaeration tube and a deaerating skimming shaped slot fluid outlet for skimming air bubbles and cooling fluid from cooling fluid flow flowing through the deaeration tube, and a fluid inlet for allowing the same amount of fluid that is skimmed off and removed through the fluid outlet to re-enter the deaeration tube to maintain mass balance in the cooling fluid flow.

2. The deaeration device of claim 1 , wherein the deaeration tube includes a top and a bottom, the top of the elongated deaeration tube including a top fluid outlet and the bottom including a fluid inlet.

3. The deaeration device of claim 1 , wherein the deaeration tube includes an incoming flow end where cooling fluid flows into the deaeration tube and an outgoing flow end where cooling flow flows out of the deaeration tube, and the fluid outlet is adjacent the incoming flow end and the fluid inlet is adjacent the outgoing flow end.

4. The deaeration device of claim 1 , wherein the deaerating skimming mechanism includes a deaeration plate declined at an angle relative to the outside diameter surface of the deaeration tube, and the angle is greater than zero degrees.

5. The deaeration device of claim 4 , wherein the deaeration plate has a substantially triangular configuration.

6. The deaeration device of claim 1 , wherein the deaeration device is part of a hybrid transit bus cooling package for both engine and electronics cooling loops.

7. The deaeration device of claim 1 , wherein the deaeration device is part of a complete rooftop cooling package for a hybrid transit bus.

8. A method of deaerating cooling fluid flow in a recirculation cooling system, the recirculation cooling system including a cooling fluid reservoir and a deaeration device submerged within cooling fluid, the deaeration device including an elongated deaeration tube having an incoming flow end where cooling fluid flows into the deaeration tube, an outgoing flow end where cooling flow flows out of the deaeration tube, including a fluid outlet and a deaerating skimming shaped slot, and a fluid inlet, comprising:

receiving fluid flow through the incoming flow end of the deaeration tube;

skimming air bubbles and cooling fluid from the cooling fluid flow through the deaeration tube with the deaerating skimming shaped slot so that the skimmed off air bubbles and cooling fluid enter cooling fluid in the cooling fluid reservoir;

receiving the same amount of cooling fluid that is skimmed off and removed through the fluid outlet into the deaeration tube through the fluid inlet to maintain mass balance in the cooling fluid flow; and

expelling the cooling fluid flow out of the outgoing flow end.

9. The method of claim 8 , wherein the deaeration tube includes a top and a bottom, the top of the elongated deaeration tube including a top fluid outlet and the bottom including a fluid inlet.

10. The method of claim 8 , wherein the fluid outlet is adjacent the incoming flow end and the fluid inlet is adjacent the outgoing flow end.

11. The method of claim 8 , wherein the deaerating skimming shaped slot includes a deaeration plate declined at an angle relative to the outside diameter surface of the deaeration tube, and the angle is greater than zero degrees.

12. The method of claim 11 , wherein the deaeration plate has a substantially triangular configuration.

13. The method of claim 8 , wherein the deaeration device is part of a hybrid transit bus cooling package for both engine and electronics cooling loops.

14. The method of claim 8 , wherein the deaeration device is part of a complete rooftop cooling package for a hybrid transit bus.
