Abstract

The present invention relates to a refrigerant module. In the refrigerant module, devices related to a vehicle cooling system can be coupled to one side of each of a first housing and a second housing which are coupled to each other while having a middle plate interposed therebetween, a first groove portion is formed in the first housing which is coupled with the second housing, a communication hole is formed in a middle plate, and a second groove portion is formed in the second housing, thereby forming a fluid channel for the refrigerant to flow inside the refrigerant module.

First claim

1 . A refrigerant manifold comprising:
a first housing in which at least one first connection part to be connected to one of devices related to a vehicle cooling system is formed on one surface thereof and a first groove part is formed to be engraved in the other surface; a second housing in which at least one second connection part to connected to one of the devices related to a vehicle cooling system is formed on one surface thereof and a second groove part is formed to be engraved in the other surface; and a middle plate of which one surface is coupled to the other surface of the first housing so that the first groove part forms a plurality of first flow paths and the other surface is coupled to the other surface of the second housing so that the second groove part forms a plurality of second flow paths, and in which a plurality of communication holes that allows the first flow path to communicate with the second flow path are formed.

2 . The refrigerant manifold of claim 1 , wherein refrigerant introduced through each of the first flow paths passes through the communication hole and flows into the second flow path that communicates with each of the first flow paths, and refrigerant introduced through each of the second flow paths passes through the communication hole and flows into the first flow path that communicates with each of the second flow paths.

3 . The refrigerant manifold of claim 2 , wherein a first connection hole is formed in the first connection part to communicate with the first flow path, and
a second connection hole is formed in the second connection part to communicate with the second flow path.

4 . The refrigerant manifold of claim 3 , wherein the first connection part includes a first valve connection part to which a first valve is connected, a second valve connection part to which a second valve is connected, and a third valve connection part to which a third valve is connected, and
the first connection hole includes a first valve connection hole, a second valve connection hole, and a third valve connection hole.

5 . The refrigerant manifold of claim 4 , wherein the second connection part includes a chiller connection part to which a chiller is connected, and the second connection hole includes a chiller inlet connection hole and a chiller outlet connection hole.

6 . The refrigerant manifold of claim 5 , wherein the second connection part includes a water-cooled condenser connection part to which a water-cooled condenser is connected, and the second connection hole includes a water-cooled condenser inlet connection hole and a water-cooled condenser outlet connection hole.

7 . The refrigerant manifold of claim 6 , wherein the second connection part includes a heat pump connection part, and the second connection hole includes a heat pump connection hole.

8 . The refrigerant manifold of claim 3 , wherein at least one third connection part to be connected to one of the devices related to the vehicle cooling system is formed on a side surface of the first housing, and
at least one fourth connection part to be connected to one of the devices related to the vehicle cooling system is formed on a side surface of the second housing.

9 . The refrigerant manifold of claim 8 , wherein a first side hole is formed in the third connection part to communicate with the first flow path, and
a second side hole is formed in the fourth connection part to communicate with the second flow path.

10 . The refrigerant manifold of claim 9 , wherein the middle plate is formed so that one surface and the other surface are formed flat, and
the other surface of the first housing in contact with the middle plate and the other surface of the second housing in contact with the middle plate are formed flat.

11 . The refrigerant manifold of claim 10 , wherein the middle plate has a shape that seals the first groove part so that the first groove part forms the first flow path and a shape that seals the second groove part so that the second groove part forms the second flow path.

12 . The refrigerant manifold of claim 11 , wherein the first groove part is formed as one or more first grooves, and each of the first grooves communicates with one or more first connection holes or one or more first side holes, and
the second groove part is formed as one or more second grooves, and each of the second grooves communicates with one or more second connection holes or one or more second side holes.

13 . The refrigerant manifold of claim 12 , wherein the first housing includes a flow path control part in which a predetermined portion of the first flow path is formed to control a moving path of a fluid flowing in the predetermined portion of the first flow path,
the predetermined portion of the first flow path communicates with the predetermined communication hole formed in the middle plate, and the predetermined communication hole communicates with a predetermined portion of the second flow path, and refrigerant flowing inside the predetermined portion of the second flow path passes through the predetermined communication hole and flows into the predetermined portion of the first flow path.

14 . The refrigerant manifold of claim 13 , wherein the flow path control part is formed as a ball valve.

15 . A refrigerant module of claim 14 , comprising:
the refrigerant manifold of claim 1 ; a water-cooled condenser coupled to the refrigerant manifold; a battery chiller coupled to the refrigerant manifold; and a plurality of multi-way valves coupled to the refrigerant manifold.
