Abstract
A light source device includes: a first light emitting element; a second light emitting element; and a heat sink configured to dissipate heat of the first light emitting element and heat of the second light emitting element. The heat sink includes: a first heat dissipation portion that is disposed on a flow path of a fluid, the first heat dissipation portion being configured to radiate the heat of the first light emitting element and the heat of the second light emitting element to the fluid; and a second heat dissipation portion that is disposed on the flow path, the second heat dissipation portion being configured to radiate the heat of the second light emitting element to the fluid.

A light source device comprising:
- a first light emitting element;
- a second light emitting element disposed adjacent to the first light emitting element;
- a heat sink disposed within a flow path of a fluid and comprising a first heat dissipation portion and a second heat dissipation portion configured to transfer heat generated by the first light emitting element and heat of the second light emitting element to the fluid
- a first heat pipe thermally connecting the first light emitting element to only the first heat dissipation portion from among the first heat dissipation portion and the second heat dissipation portion;
- and
- a second heat pipe thermally connecting the second light emitting element to the first heat dissipation portion and to the second heat dissipation portion.
A heat exchanger for a light source device comprising:
- a heat sink configured to be disposed within a flow path of a fluid and comprising a first heat dissipation portion and a second heat dissipation portion that are adjacent to one another
- a first heat pipe thermally connected to only the first heat dissipation portion from among the first heat dissipation portion and the second heat dissipation portion and configured to be thermally connected to a first light emitting element;
- and
- a second heat pipe thermally connected to the first heat dissipation portion and the second heat dissipation portion and configured to be thermally connected to a second light emitting element.
A method of cooling a first light emitting element and a second light emitting element that is disposed adjacent to the first light emitting element which are both thermally connected to a heat sink that includes a first heat dissipation portion and a second heat dissipation portion disposed within a flow path of a fluid, the method comprising:
- transferring heat from the first light emitting element to a first heat pipe;
- transferring heat from the second light emitting element to a second heat pipe;
- transferring heat from the first heat pipe to only the first heat dissipation portion from among the first heat dissipation portion and the second heat dissipation portion;
- and
- transferring heat from the second heat pipe to the first heat dissipation portion and to the second heat dissipation portion.
