Abstract:
1. An endoscope apparatus having a scope section which includes at least a front-end portion and a shaft portion, the endoscope apparatus comprising: a heat exchanger which is installed near the front-end portion, and which has a channel for a cooling liquid for cooling a functional component which generates heat, the functional component being disposed in the front-end portion; a first tube having one end connected to one end of the channel of the heat exchanger; a second tube having one end connected to an other end of the channel of the heat exchanger, and an actuator in fluid communication with one of the first and second tubes and disposed so as to be reciprocated in a first and second direction, wherein the front-end portion is cooled down by alternating reciprocations of the actuator in a repetitive manner to generate a first flow of the cooling liquid from the first tube through the heat exchanger to the second tube when the actuator is reciprocated in the first direction and to generate a second flow of the cooling liquid from the second tube through the heat exchanger to the first tube when the actuator is reciprocated in the second direction.
