Abstract

An integrated thermal management module for a vehicle may include a chiller; a first reservoir portion through which electric part-cooling water passes, and a second reservoir portion through which high-voltage battery-cooling water passes; a first pump that circulates the electric part-cooling water through an electric portion, and a first valve that controls cooling water that has passed through the chiller or cooling water of the first reservoir portion to be selectively circulated through the electric portion by the first pump; and a second pump that circulates the high-voltage battery-cooling water through a high-voltage battery, and a second valve that controls the cooling water that has passed through the chiller or cooling water of the second reservoir portion to be selectively circulated through the high-voltage battery by the second pump.

First claim

What is claimed is:

1. An integrated thermal management module for a vehicle, the module comprising:
a chiller through which refrigerant and cooling water pass to exchange heat with each other;
a first reservoir portion through which electric part-cooling water passes;
a second reservoir portion through which battery-cooling water passes;
a first pump that circulates the electric part-cooling water through an electric portion;
a first valve that controls the cooling water that has passed through the chiller or cooling water of the first reservoir portion to be selectively circulated through the electric portion by the first pump; and
a second pump that circulates the battery-cooling water through a battery; and
a second valve that controls the cooling water that has passed through the chiller or cooling water of the second reservoir portion to be selectively circulated through the battery by the second pump,
wherein the first valve is a three-way valve and is fluidically connected to a lower portion of the first reservoir portion, a lower portion of the chiller, and an inlet of the first pump, and
wherein the second valve is a three-way valve and is fluidically connected to a lower portion of the second reservoir portion, a lower portion of the chiller, and an inlet of the second pump.

2. The integrated thermal management module of claim 1 ,
wherein the chiller, the first reservoir portion, and the second reservoir portion form one assembly by being directly or indirectly connected to one another.

3. The integrated thermal management module of claim 1 ,
wherein the first reservoir portion, the first pump, and the first valve form one assembly by being directly or indirectly connected to one another.

4. The integrated thermal management module of claim 1 ,
wherein the second reservoir portion, the second pump, and the second valve form one assembly by being directly or indirectly connected to one another.

5. The integrated thermal management module of claim 1 ,
wherein the first reservoir portion and the second reservoir portion are spaced a predetermined distance apart from each other and form one reservoir tank with upper portions of internal spaces connected to each other.

6. The integrated thermal management module of claim 1 ,
wherein the first valve controls the electric part-cooling water of the first reservoir portion or the cooling water of the chiller to be supplied to the first pump.

7. The integrated thermal management module of claim 1 ,
wherein the second valve controls the battery-cooling water of the second reservoir portion or the cooling water of the chiller to be supplied to the second pump.

8. The integrated thermal management module of claim 1 ,
wherein the chiller, the first reservoir portion, the second reservoir portion, the first valve, the second valve, the first pump, and the second pump are formed as one assembly by being directly or indirectly connected to one another, and the one assembly is mounted on a vehicle body by fastening the first reservoir portion or the second reservoir portion to the vehicle body through a damper.

9. The integrated thermal management module of claim 1 ,
wherein the first pump and the second pump are mounted so that axes of rotation shafts of the first pump and the second pump cross each other.

10. The integrated thermal management module of claim 1 ,
wherein the first reservoir portion and the second reservoir portion are spaced a predetermined distance apart from each other and form one reservoir tank with upper portions of internal spaces connected to each other, the first valve and the first pump are mounted under the first reservoir portion, and the second valve and the second pump are mounted under the second reservoir portion.

11. The integrated thermal management module of claim 1 ,
wherein an inlet of the first reservoir portion is connected to an electric portion radiator, an outlet of the first reservoir portion is connected to the first valve, and an outlet of the first pump is connected to the electric portion.

12. The integrated thermal management module of claim 1 ,
wherein an inlet of the second reservoir portion is connected to a battery radiator, an outlet of the second reservoir portion is connected to the second valve, and an outlet of the second pump is connected to the battery.

13. The integrated thermal management module of claim 1 ,
wherein the chiller has a first inlet, a second inlet, a first outlet, and a second outlet for flow of cooling water, the first inlet is connected to the electric portion, and the first outlet is connected to the first valve.

14. The integrated thermal management module of claim 13 ,
wherein the second inlet of the chiller is connected to the battery and the second outlet of the chiller is connected to the second valve.

15. The integrated thermal management module of claim 1 ,
wherein the first reservoir portion and the second reservoir portion are mounted adjacent to each other and the chiller is mounted adjacent to a side of the first reservoir portion and the second reservoir portion.
