Abstract

A cooling device includes a cooler disposed inside a shell main body formed in a cylindrical shape, and having a first surface facing an inlet nozzle and an outlet nozzle, and a partition member fixed to the first surface, and partitioning a portion between the cooler and an inner peripheral surface of the shell main body into a first space communicating with the inlet nozzle and a second space communicating with the outlet nozzle. The partition member includes a main partition plate disposed between the inlet nozzle and the outlet nozzle in an axial direction, a first guide portion extending from an end portion of the main partition plate toward a first end surface of the shell main body, and a second guide portion extending from an end portion of the main partition plate toward a second end surface of the shell main body.

First claim

What is claimed is:

1. A cooling device comprising:
a shell having a shell main body formed in a cylindrical shape extending around an axis, an inlet nozzle configured to feed a fluid into the shell main body, and an outlet nozzle disposed away from the inlet nozzle in an axial direction in which the axis extends and configured to feed the fluid inside the shell main body to an outside of the shell main body;
a cooler disposed inside the shell main body, configured to cool the fluid flowing from the inlet nozzle toward the outlet nozzle by internally circulating the fluid, and having a first surface extending in the axial direction to face the inlet nozzle and the outlet nozzle; and
a partition member fixed to the first surface, and partitioning a space portion between the cooler and an inner peripheral surface of the shell main body into a first space communicating with the inlet nozzle and a second space communicating with the outlet nozzle,
wherein the partition member includes
a main partition plate disposed between the inlet nozzle and the outlet nozzle in the axial direction, and extending from the first surface to the inner peripheral surface of the shell main body to spread in a direction intersecting with the axis,
a first guide portion extending from an end portion on a first side of the main partition plate in the direction intersecting with the axis toward a first end surface of the shell main body close to the inlet nozzle in the axial direction, and
a second guide portion extending from an end portion on a second side of the main partition plate in the direction intersecting with the axis toward a second end surface of the shell main body close to the outlet nozzle in the axial direction.

2. The cooling device according to claim 1 ,
wherein the main partition plate is disposed at a position close to the second end surface of the shell main body with respect to a central portion of the first surface in the axial direction.

3. The cooling device according to claim 1 ,
wherein the second guide portion has a second guide surface extending from the first surface to the inner peripheral surface of the shell main body and inclined to face the outlet nozzle.

4. The cooling device according to claim 1 ,
wherein the first guide portion has a first guide surface extending from the first surface to the inner peripheral surface of the shell main body and inclined to face the inlet nozzle.

5. The cooling device according to claim 1 ,
wherein the main partition plate is disposed at a position away from an end portion of the first surface in a width direction orthogonal to the axis, and
the second guide portion extends in the axial direction at a position away from the end portion of the first surface in the width direction.

6. The cooling device according to claim 1 , further comprising:
a perforated plate disposed to cover a side surface into which the fluid flows in the cooler, and having a plurality of holes.

7. The cooling device according to claim 1 ,
wherein the cooler includes
a plurality of cooling tubes extending in the axial direction, and which a cooling medium configured to flow therein, and
a plurality of fin plates having a plate shape orthogonal to the axial direction, disposed at a distance in the axial direction, and having a plurality of tube insertion holes for fixing the plurality of cooling tubes in a state where the plurality of cooling tubes are inserted in the axial direction, and

each of the plurality of fin plates has a turbulent flow portion configured to disturb a flow of the fluid between the plurality of tube insertion holes.

8. The cooling device according to claim 7 ,
wherein the turbulent flow portion has a protrusion portion having a cylindrical shape to have a through-hole penetrating in the axial direction, and protruding in the axial direction.

9. The cooling device according to claim 8 ,
wherein the protrusion portion protrudes to be in contact with another fin plate adjacent in the axial direction among the plurality of fin plates.

10. The cooling device according to claim 7 ,
wherein the plurality of the tube insertion holes are disposed so that a center lines of three tube insertion holes closest to one another form a triangle when viewed in the axial direction, and
the turbulent flow portion is disposed to be located at a center of the triangle.
