Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a so-called surface-type condensing device that cools a solid surface with a cold / hot refrigerant and indirectly exchanges heat through a solid wall. [Prior Art] In a surface-type condensing device, vapor is condensed on a solid surface cooled by a refrigerant. In this case, if the condensate stays on the surface of the solid, the heat exchange rate is deteriorated, and as a result, the condensation efficiency is lowered. Therefore, in the conventional condensing device, as shown in FIG. 4, the grooves 51, 51, ... Are formed on the outer surface of the condensing pipe 5 in the axial direction, and the liquid condensed at the tips of the fins 52, 52 ,. , Were collected in the grooves 51, 51, ... By surface tension and flowed down in the grooves 51, 51 ,. [Problems to be Solved by the Invention] By the way, in the conventional condensing device, since the condensate in the grooves 51, 51, ... Is caused to flow down by gravity, the gravity acting on the condensate causes the condensate to flow there. Until the surface tension to be stopped becomes larger than the condensate, the condensate is not absorbed by the grooves 51, 51, ...
There was a disadvantage that the condensation efficiency was inevitably lowered as a result of retention in the interior. (Structure of the Invention) [Means for Solving Problems] An object of the present invention is to eliminate the above-mentioned inconvenience. Further, this object is provided with a supply header and a discharge header through which a refrigerant flows, and a plurality of condensing pipes, one end of the condensing pipe is directly connected to the supply header, and the other end of the condensing pipe is directly connected to the discharge header. The condensing tubes are arranged substantially parallel to each other with a space therebetween, and a plurality of fine wires are brought into close contact with each other in a plain weave pattern in a direction intersecting with the condensing tubes so as to intersect with the condensing tubes. This is achieved by condensing the flowing gas by the refrigerant and at the same time diffusing the liquid that condenses and adheres to the outer peripheral surface of the condensing tube by the capillary phenomenon due to the fine wire of the plain weave shape. [Operation of the Invention] In the condensing device according to the present invention, since the plurality of fine wires are brought into contact with each other in a plain weave state in a dense state in a direction intersecting with the condensing pipe, the outer peripheral surface of the condensing pipe is provided with mutual thin wires. The minute spaces to be formed are formed innumerably in the direction intersecting the condensing tube. As a result, the liquid condensed on the outer peripheral surface of the condensing tube is diffused in the direction of the thin line due to the capillary phenomenon working in this minute space almost at the same time as the condensation, and the intersection of the thin lines formed between the condensing pipe and the condensing pipe. Is sucked into the club. Then, the sucked condensate is further diffused in the direction of the adjacent intersection, that is, in the direction of the condensing tube by the capillary phenomenon. Description of Embodiments An embodiment of the present invention will be described with reference to FIGS. 1 to 3. In FIG. 1, 1 is a supply header of the condenser C and 2 is a discharge header. These 1 and 2 are arranged substantially parallel to each other with a predetermined interval. .. are condensing pipes, one end of which is connected to the supply header 1 and the other end of which is connected to the discharge header 2. These condensing tubes 3, 3, ... Are arranged at equal intervals in a planar state. These condensing pipes 3, 3, ... Are parts through which the refrigerant passes, and the refrigerant divided by the supply header 1 into these condensing pipes 3, 3, .. It flows into header 2. 2 and 3, 4, 4, ... Are copper wires having a diameter of 0.3 to 0.4 mm, which correspond to the thin wires of the present invention.
It is plain woven in a dense state with respect to 3, ... (See FIGS. 2 and 3). 41, 41, ... Are minute gaps and are formed between a pair of copper wires 4, 4 adjacent to each other. This small gap 41,41, ...
Are opened on the outer peripheral surfaces of the condensation tubes 3, 3, ... And are formed innumerably in a direction intersecting with the condensation tubes 3 (see FIGS. 2 and 3). Therefore, the liquid condensed on the outer surface of the condensing tubes 3, 3, ...
Capacitor attraction of 1,41, ... Diffuses in the direction of the copper wires 4,4, ..., and moves toward the crossing portion 42 between the condensing tubes 3 and the thin wires formed between the condensing tubes 3. Therefore, the condensate does not always exist on the outer side surfaces of the condenser tubes 3, 3, .... Copper wire 4,4, ...
Condensation is also carried out on the surface of, but the liquid produced by this condensation is also collected at the intersection 42 by the capillary action of the minute gaps 41, 41, .... The condensate collected in the intersection 42 is further diffused in the direction of the intersection 42 (V direction in FIG. 1) of the adjacent thin wires by the capillary phenomenon. Although copper wire is used as the thin wire in this embodiment, any wire having corrosion resistance and heat resistance such as stainless wire, titanium wire, inconel wire, ceramic fiber, glass fiber and carbon fiber may be used. Further, in this embodiment, the thin wires which are adjacent to each other are woven so as to be in intimate contact with each other at the crossing portion, but it is not always necessary that they are in intimate contact. The point is to choose a distance between lines that can expect a capillary phenomenon. Further, although the condenser tube 3 is installed in the vertical direction in this embodiment, it does not hinder the installation in the horizontal direction. Further, in this embodiment, the thin wire 4 is plain-woven with respect to the condensing pipe 3, but the thin wire 3 is formed in a wave shape and arranged separately above and below the condensing pipe 3, and the condensing pipe 3 is sandwiched between the upper and lower thin wires 3. (In the state where the condensing pipe 3 is surrounded by the wavy portion), it may be installed like a plain weave. The condensing device according to the present invention includes not only a device for condensing gas 100% but also a device for removing water in the gas. (Effect of the Invention) In the condenser according to the present invention, a plurality of fine wires are contacted in a plain weave shape in a dense state in a direction intersecting with the condensing pipe. The minute space to be formed is formed innumerably in the direction crossing the condensing tube. As a result, the liquid condensed on the outer peripheral surface of the condensing pipe is diffused in the direction of the fine line due to the capillary phenomenon working in this minute space almost at the same time as the condensing, and the intersection of the fine lines formed between the condensing pipe and the condensing pipe. Is sucked into the club. Then, the sucked condensate is further diffused in the direction of the adjacent intersection, that is, in the direction of the condensing tube by the capillary phenomenon. Therefore, if this condensing device is used, the condensed liquid hardly stays on the outer surface of the condensing tube, and the condensing efficiency is improved.
