<p>A coolant supply device is disclosed. The coolant supply device comprises: an adapter block to and from which multiple radiators are selectively attached and detached, to inject a coolant to a radiator heat-exchanged with heat generated in a lighting unit provided with multiple light emitting members; a vacuum block which converts the inside of the radiators into a vacuum state; a coolant supply block which supplies a coolant to the radiators while keeping a vacuum degree for the radiators; and a purge block which is connected to remove an extra coolant remaining in the adaptor block after the coolant injection to the radiators is completed. A coolant injecting method of a coolant supply device comprises the steps of: simultaneously mounting multiple radiators separated from a lighting unit, to inject a coolant to a radiator heat-exchanged with heat generated in the lighting unit provided with multiple light emitting members; converting the inside of the radiators into a vacuum state; supplying a coolant to the radiators; while keeping a vacuum degree for the radiators; and performing a purge of the coolant remaining in a passage connected to the radiators in a state where the radiators are mounted on the coolant supply device.</p> |
