Abstract

A reservoir tank includes first and second chambers separated by partitions. The first chamber is configured such that coolant circulates through the first chamber. The second chamber is provided on a side and spaced apart from the first chamber and is configured such that coolant having a different temperature from the coolant stored in the first chamber circulates through the second chamber. A first partition and a second partition are provided so as to separate the first chamber and the second chamber from each other, and are spaced apart from and facing each other. A middle chamber is defined in a space between the first partition and the second partition and configured such that the coolant from the first chamber or the second chamber circulates through the middle chamber, thereby providing a heat buffer between the first chamber and the second chamber.

First claim

What is claimed is:

1. A reservoir tank, comprising:
a first chamber configured such that coolant circulates through the first chamber or is stored in the first chamber;
a second chamber provided on a side and spaced apart from the first chamber and configured such that coolant having a different temperature from the coolant stored in the first chamber circulates through the second chamber or is stored in the second chamber;
a first partition and a second partition provided in a space between the first chamber and the second chamber to separate the first chamber and the second chamber from each other, and spaced apart from and facing each other; and
a middle chamber defined in a space between the first partition and the second partition and configured such that the coolant from the first chamber or the second chamber circulates through the middle chamber or is stored in the middle chamber, thereby providing a heat buffer between the first chamber and the second chamber,
wherein a baffle plate covering an upper end of the first chamber, the middle chamber, or the second chamber is provided on top of the first partition and the second partition, and gas within the first chamber, the middle chamber, or the second chamber is discharged above the first chamber, the middle chamber, or the second chamber through the baffle plate.

2. The reservoir tank according to claim 1 , wherein a circulation hole is provided in a lower end of the first partition or the second partition,
such that if the circulation hole is provided in the first partition, heat exchange occurs between the coolant in the first chamber and the coolant in the middle chamber, or
if the circulation hole is provided in the second partition, heat exchange occurs between the coolant in the second chamber and the coolant in the middle chamber.

3. The reservoir tank according to claim 1 , wherein the middle chamber performs heat exchange with the first chamber and the second chamber through the first partition and the second partition, such that a temperature of the coolant circulating or stored in the middle chamber is between a temperature of the coolant in the first chamber and a temperature of the coolant in the second chamber.

4. The reservoir tank according to claim 2 , wherein an input channel through which the coolant is introduced to the first chamber or the second chamber and an output channel through which the coolant is discharged from the first chamber or the second chamber are provided outside the first chamber or the second chamber, the input channel and the output channel being provided integrally with the first chamber or the second chamber.

5. The reservoir tank according to claim 4 , wherein the circulation hole is narrower than either the input channel or the output channel of the first chamber or the second chamber, and a flow rate of the coolant flowing through the circulation hole is less than a flow rate of the coolant flowing through either the input channel or the output channel.

6. The reservoir tank according to claim 4 , wherein the input channel is provided above the output channel, and the coolant introduced to the first chamber or the second chamber through the input channel is introduced to the middle chamber through the circulation hole or is discharged from the first chamber or the second chamber through the output channel.

7. The reservoir tank according to claim 4 , wherein a coupling recess to which a pump is coupled is provided integrally with the first chamber or the second chamber, in a position outside a lower portion of the first chamber or the second chamber, and when the output channel is connected to the coupling recess and the pump coupled to the coupling recess operates, the coolant circulates through the input channel or the output channel.

8. The reservoir tank according to claim 7 , wherein when the pump is coupled to the coupling recess, an impeller or a pump housing of the pump is located in the coupling recess and a coolant nozzle is provided on a sidewall of the coupling recess.

9. The reservoir tank according to claim 1 , wherein open holes are provided in upper ends of the first partition and the second partition, and the coolant is exchanged among the first chamber, the middle chamber, and the second chamber through the open holes.

10. The reservoir tank according to claim 1 , wherein one or more tank caps are provided on top of the first chamber, the middle chamber, or the second chamber,
the coolant is supplied to the first chamber, the middle chamber, or the second chamber through the tank caps, or gas is discharged from inside the first chamber, the middle chamber, or the second chamber through the tank caps.

11. A reservoir tank, comprising:
a first chamber configured such that coolant circulates through the first chamber or is stored in the first chamber;
a second chamber provided on a side and spaced apart from the first chamber and configured such that coolant having a different temperature from the coolant stored in the first chamber circulates through the second chamber or is stored in the second chamber;
a first partition and a second partition provided in a space between the first chamber and the second chamber to separate the first chamber and the second chamber from each other, and spaced apart from and facing each other; and
a middle chamber defined in a space between the first partition and the second partition and configured such that the coolant from the first chamber or the second chamber circulates through the middle chamber or is stored in the middle chamber, thereby providing a heat buffer between the first chamber and the second chamber,
wherein an input channel through which the coolant is introduced to the first chamber or the second chamber and an output channel through which the coolant is discharged from the first chamber or the second chamber are provided outside the first chamber or the second chamber, the input channel and the output channel being provided integrally with the first chamber or the second chamber, and
wherein a coupling recess to which a pump is coupled is provided integrally with the first chamber or the second chamber, in a position outside a lower portion of the first chamber or the second chamber, and when the output channel is connected to the coupling recess and the pump coupled to the coupling recess operates, the coolant circulates through the input channel or the output channel.
