Since this is an open matter, no full text was included.

1 is a longitudinal sectional view of an embodiment of a heat pipe according to the present invention;

2 and 3 are explanatory views of the manufacturing method of the heat exchanger tube shown in FIG.

Claims (11)

In the falling film type heat transfer tube, a fin is formed on the surface of the heat transfer tube, and the pitch and height of the fin are set such that the tip of at least one of the fins adjacent to each other and one point of the surface of the heat transfer tube form an arc. Heat pipe. The heat transfer pipe according to claim 1, wherein the pitch p and the height h of the fin are set in a relationship of p = h (1.6 to 2.4). The heat exchanger tube according to claim 1, wherein a bent portion is formed at the tip of the fin. 4. The heat exchanger tube according to claim 3, wherein fine projections are formed on a surface of the bent portion. In the falling film type heat transfer tube, a plurality of fins are formed on the surface of the heat transfer tube, and the pitch and height of the fins are set so that an edge formed by one end of the fins and the surface of the heat transfer tube forms an arc. Heat pipe. In the falling film type heat transfer tube, a fin is formed on the surface of the heat transfer tube, and the pitch and height of the fin are set so that the tip of at least one of the fins adjacent to each other and the surface of the solution attached to the heat transfer tube form an arc. Heat pipes characterized in that. In the falling film type heat transfer tube, a fin is formed on the surface of the heat transfer tube, and the pitch (p) and the height (h) of the fin are formed such that the tip of at least one fin adjacent to each other and one point of the heat transfer tube form an arc. Heat exchanger tube characterized in that the setting so as to be. p = h (1.6-2.4) In the falling film type heat transfer tube, a fin is formed on the surface of the heat transfer tube, the pitch and height of the fin are set such that the tip of the at least one fin and the surface of the heat transfer tube that are mutually formed form an arc. A heat transfer pipe, characterized by forming a bent portion at the tip. In a heat exchanger in which a heat exchanger tube is configured to exchange heat between heat pipes flowing inside and outside a tube, the heat transfer tube forms fins on the surface of the heat transfer tube, and one end of at least one of the fins adjacent to each other and the surface of the heat transfer tube form an arc. And a pitch and a height of the fins are set. In a heat exchanger incorporating a heat exchanger tube for heat exchange between a heat medium flowing inside and outside a tube, the heat transfer tube forms fins on the surface of the heat transfer tube, and the fins formed at one end of the fins and the surface of the heat transfer tube form an arc. Heat exchanger, characterized in that the pitch and height of the set. In a heat exchanger incorporating a heat exchanger tube for heat exchange between a heat medium flowing inside and outside a tube, the heat transfer tube forms fins on the surface of the heat transfer tube, and the end of at least one of the fins adjacent to each other and the solution attached to the heat transfer tube surface. The heat exchanger characterized in that the pitch and height of the fin is set so that the surface forms an arc. ※ Note: The disclosure is based on the initial application.
