Abstract
The cooling device comprises a heat exchange unit provided in a cooling water flow path. The heat exchange unit has a plate part in the form of a plate and multiple fins erected on the plate face of the plate part, and provided in the manner that the plate face of the plate part extends along the cooling water flow path and the cooling water runs through the space between the fins. The multiple fins are each in the form of a rhombic column and provided on the plate part in a lattice pattern in the manner that the longer diagonal of the rhombic column extends along the cooling water flow path.
Claims9
A cooler provided in a cooling water flow path for heat exchange with cooling water, comprising:
- a plate configured to have a plate face facing the cooling water;
- and
- fins coupled to the plate face in a lattice pattern and provided in the cooling water flow path,
- wherein the fins are in the form of a rhombic column with a longer diagonal of a rhombus of the rhombic column extending in the direction of the cooling water flow path.
A cooler provided in a cooling water flow path for heat exchange with cooling water, comprising:
- a stacked structure that comprises heat exchange plates, wherein the heat exchange plates are stacked in a direction perpendicular to a direction of the cooling water flow path, an each plate of the heat exchange plates comprises slits formed through the thickness of the each plate, and the slits are formed in an overall direction parallel to the direction of the cooling water flow path so that the cooling water circulates through the slits,
- wherein the slits are at least partially zigzagged and have a successive angled pattern in which adjacent slits of adjacent heat exchange plates are in opposite phases with each other when viewed from a direction perpendicular to the plate faces.
A cooling device, comprising:
- a cooler within a cooling water flow path for heat exchange with cooling water, comprising:
- a stacked structure that comprises heat exchange plates, wherein the heat exchange plates are stacked in a direction perpendicular to a direction of the cooling water flow path, an each plate of the heat exchange plates comprises slits formed through the thickness of the each plate, and the slits are formed in an overall direction parallel to the direction of the cooling water flow path so that the cooling water circulates through the slits,
- wherein the slits are at least partially zigzagged and have a successive angled pattern in which adjacent slits of adjacent heat exchange plates are in opposite phases with each other when viewed from a direction perpendicular to the plate faces,
- wherein widened parts that are widened in the stacking direction of the stacked structure are formed at the cooling water inlet and outlet to the cooler in the flow path, and the cooling water flows in/out perpendicularly to the plate faces of the heat exchange plates via the widened parts.
