The specific embodiment
Below explain the heat pipe that the absorption chilled and hot water apparatus of embodiment of the present invention is used with reference to the accompanying drawings.
Fig. 2 A is the oblique view that is provided with the heat pipe of using with the absorption chilled and hot water apparatus of 2 grades of step-like juts of expression one embodiment of the present invention.In addition, Fig. 2 B is the sectional view along the heat pipe of the A-A line of Fig. 2 A.Shown in Fig. 2 A and 2B, be provided with a plurality of step-like juts 10 along the length direction of heat pipe 20 at the outer surface of heat pipe 20 of the present invention.Described jut 10 is configured to row along the length direction of described heat pipe 20.The certain intervals that separates on every side that is listed in heat pipe 20 of this jut 10 disposes.Interval between the row of the jut 10 that separates the certain intervals configuration around the described heat pipe 20 becomes the passage that fluid flows.In addition, the interval between each jut 10 of the length direction of heat pipe 20 also becomes the passage that fluid flows in the row of jut 10.
Shown in Fig. 2 A and Fig. 2 B, the whole height t that is set to 2 grades of step-like described juts 10 is 0.30～0.36mm.Here, the height a of the first order is 0.20～0.24mm, and the 2nd grade height b is 0.10～0.12mm.In addition, the width w of the length direction of described jut 10 is 2.0～2.5mm, and the width e of the 2nd grade length direction is 1.0～1.5mm.The width d of described jut 10 and jut 10 is 0.5～1.0mm.
