Abstract

The present invention relates to a water-cooling type condenser, and more specifically, to a water-cooling type condenser including a fixing plate for fixing a gas and liquid separator, wherein the fixing plate is formed to enable a refrigerant and cooling water to flow by means of coupling between first and second plate portions, and is integrally formed, by brazing, with remaining components (a plate, a first inlet pipe, a first outlet pipe, a second inlet pipe, and a second outlet pipe), so as to enhance assemblability and durability and enable size reduction.

First claim

The invention claimed is:

1. A water-cooling type condenser comprising:
a condensation area condensing a refrigerant by heat exchanging the refrigerant and cooling water;
a gas and liquid separator separating gas and liquid from the refrigerant condensed in the condensation area;
a supercooling area supercooling the refrigerant by heat exchanging the refrigerant passing through the gas and liquid separator and the cooling water; and
a fixing plate in which a first plate portion corresponding to the condensation area and a second plate portion corresponding to the supercooling area are combined to face each other, flowing the refrigerant and the cooling water and fixing a partial wall surface of the gas and liquid separator,
wherein a plurality of plates are stacked to alternately form a first flow portion and a second flow portion through which the refrigerant and the cooling water respectively flow and form the condensation area and the supercooling area,
wherein the first plate portion and the second plate portion have a shape corresponding to the plate,
wherein the gas and liquid separator includes a cylindrical body,
wherein the fixing plate includes an extension portion extending from each of the first plate portion and the second plate portion to surround an outer circumference surface of the body of the gas and liquid separator, and
wherein the fixing plate includes a protruding bonding portion in which certain areas of the first plate portion and the second plate portion protrude to be surface-bonded to each other.

2. The water-cooling type condenser of claim 1 , further including:
a first inlet pipe through which the refrigerant flows into and a first outlet pipe through which the refrigerant is discharged; and
a second inlet pipe through which the cooling water flows into and a second outlet pipe through which the cooling water is discharged.

3. The water-cooling type condenser of claim 2 ,
wherein the plate, the first inlet pipe, the first outlet pipe, the second inlet pipe, the second outlet pipe, the body of the gas and liquid separator, and the fixing plate are integrally formed by brazing.

4. The water-cooling type condenser of claim 1 ,
wherein the plate includes a first communication portion and a second communication portion having a hollow circumference protruding to one side or the other side of the plate to adjust a movement flow of the refrigerant, and a third communication portion and a fourth communication portion having a hollow circumference protruding opposite to the protruding direction of the first communication portion and the second communication portion to adjust a movement flow of the cooling water.

5. The water-cooling type condenser of claim 4 ,
wherein, in the plate, the first communication portion and the second communication portion are located at upper and lower sides in a longitudinal direction from one side in a width direction of the plate, and the third communication portion and the fourth communication portion are located at the upper and lower sides in the longitudinal direction from the other side in the width direction of the plate.

6. The water-cooling type condenser of claim 5 ,
wherein, in the fixing plate, a plurality of protruding bonding portions are formed in the longitudinal direction of the plate, some protruding bonding portions are formed at locations corresponding to the first communication portion to the fourth communication portion, and a certain area is hollow or closed.

7. The water-cooling type condenser of claim 6 ,
wherein the gas and liquid separator includes a first hollow hole and a second hollow hole, and
wherein the refrigerant is conveyed by a first connection pipe connecting the first hollow hole and one side of the protruding bonding portion formed on a location corresponding to the second communication portion and a second connection pipe connecting the second hollow hole and one side of the protruding bonding portion formed on a location corresponding to the first communication portion.

8. The water-cooling type condenser of claim 7 ,
wherein the fixing plate includes a seating groove so that certain areas of the first connection pipe and the second connection pipe are inserted into the protruding bonding portions on locations corresponding to the second communication portion and the first communication portion.

9. The water-cooling type condenser of claim 7 ,
wherein the first connection pipe and the second connection pipe include a step portion having a tubal shape and protruding along an outer circumferential surface to limit an insertion depth of both ends.

10. The water-cooling type condenser of claim 7 ,
wherein the pair of protruding bonding portions are fixed to each other so as to maintain a temporary assembly state of the gas and liquid separator, the first connection pipe, the second connection pipe, and the fixing plate.

11. The water-cooling type condenser of claim 10 ,
wherein a first fixing hole is formed in the protruding bonding portion, and a separate fixing means is coupled through a first fixing hole.

12. The water-cooling type condenser of claim 10 ,
wherein a convex portion having a certain protruding area is formed on one side of the pair of protruding bonding portions and a concave portion into which the convex portion is inserted is formed on the other side.

13. The water-cooling type condenser of claim 1 ,
wherein the fixing plate includes a first bending portion in which a circumference of the first plate portion is bent and extends toward the condensation area so that plates forming the condensation area are stacked and a second bending portion in which a circumference of the second plate portion is bent and extends toward the supercooling area so that plates forming the supercooling area are stacked.

14. The water-cooling type condenser of claim 4 ,
wherein a refrigerant is discharged through the first outlet pipe by passing through a condensation area in which the refrigerant flowing into through the first inlet pipe is condensed while passing through the first flow portion, a gas and liquid separation area in which the refrigerant flows into the gas and liquid separator through the first connection pipe and is separated into gas and liquid refrigerants, and a supercooling area in which only the separated liquid refrigerant moves through the second connection pipe and is supercooled while passing through the first flow portion.

15. The water-cooling type condenser of claim 2 ,
wherein cooling water flowing into through the second inlet pipe flows through the second flow portion and is discharged through the second outlet pipe.

16. The water-cooling type condenser of claim 1 , further including: a bracket having a certain area fixed between the first plate portion and the second plate portion,
wherein the fixing plate includes a bracket fixing portion from which a certain area of the first plate portion and the second plate portion protrudes to fix the bracket by forming spaced spaces apart from each other by a certain distance.

17. The water-cooling type condenser of claim 16 ,
wherein the bracket includes a contact portion closely fixed to the spaced spaces of the bracket fixing portion, and a mounting portion extending from the contact portion for vehicle mounting.

18. The water-cooling type condenser of claim 17 ,
wherein bracket fixing portions are formed on the upper and lower sides, respectively,
wherein the contact portion of the bracket from which the mounting portion protrudes to the upper side is f
