摘要： A heatsink includes: a base plate thermally connected to a heat-generating unit; a plurality of heat radiation fins erected on a surface of the base plate, and arranged with gaps in a first direction along the surface; and a partition member provided to intersect the plurality of heat radiation fins, and partitioning the plurality of heat radiation fins in a second direction along the surface and intersecting the first direction. The partition member partitions the plurality of heat radiation fins such that more air passes through in the second direction between the plurality of heat radiation fins on a base plate side than on a side opposite to the base plate side.

摘要： An active energy radiation unit includes a light source which radiates ultraviolet rays onto a target object, and a main gas supply mechanism which is disposed to be adjacent to the light source and ejects an inert gas. The main gas supply mechanism includes a receiving part which receives the inert gas, and a main ejection port which is provided at a position between the receiving part and the light source and closer to the target object than the receiving part. A flow path area from the receiving part to the main ejection port is constant.

摘要： A light source device includes a housing having a great length along a predetermined direction, a plurality of light emitting elements which are placed in the housing and are arranged along the predetermined direction, and one or more heat dissipation members which are placed in the housing and are thermally connected with the light emitting elements. A first intake port through which air is sucked into the housing is provided in one end in the housing. An exhaust port through which air is discharged to an outside is provided in the other end in the housing. A space where the other side in the predetermined direction faces the heat dissipation member is formed in the housing. A second intake port through which air is sucked into the space from the outside is provided in a side surface between the first intake port and the exhaust port in the housing.

摘要： A light emitting device includes a housing; a light source unit; and a cooling unit provided in the housing to discharge heat to an outside of the housing by means of a gas, the heat being generated by the light source unit. The cooling unit includes an introduction portion, a heat exchange portion, and a circulation portion that guides the gas from the introduction portion to the heat exchange portion. The circulation portion includes a first flow path receiving the gas from the introduction portion, and a second flow path receiving the gas from the first flow path, and being connected to the heat exchange portion. The first flow path includes a portion having a flow path area larger than a flow path area of the introduction portion.
