TH9517B - Heat exchanger for air conditioning and how to build a heat exchanger - Google Patents

Abstract

Heat exchanger for air conditioner Consisting of a transfer pipe A certain amount of heat They are arranged parallel to each other by specified spaced intervals and the heat transfer fins created by a number of small coils in place. Around a number of heat transfer pipes In the given alternative, the heat transfer tubes are divided. It is a group of two adjacent heat transfer pipes (1a, 1b), (1b, 1c), (1c, 1d) ........... And at the very least, one of the tiny fins is coiled around the adjacent heat exchanger tubes. The two tubes of each group are coiled around in such a way that the smaller wire fins do not cross through. Another of small wire fins With the direction of view perpendicular to the plane including the axis of the A number of heat transfer pipes While building the heat exchanger, at least part of the outer circumference of the heat exchanger tube. Or outer circumference Of the small wires are coated with a metal film created by plating And later the transfer pipe The heat is poured and the small wires are then rubbed together to form a structure. Heat exchanger And the heat exchanger structure is heated to the melting point of the metal film to make the metal film melt. And heat transfer pipes and small wires Will be welded together by a molten metal film.

Claims (8)

1. A heat exchanger consists of a number of heat transfer tubes that are arranged in parallel according to the distance Determined, heat transfer tubes are divided into groups of two adjacent heat exchanger tubes, each group having a common pipe with each of the adjacent groups and a number of smaller wire fins. Which serves as one or more heat transfer fins of the tiny wire fins. Will be wrapped in a spiral around the heat transfer pipe Near the two pipes of each group So that the tiny wire fins wrapped around a group of tubes It does not cross the part of another small wire fin that is wrapped around another group. And do not cross through the section Another of the same small wire fins wrapped around the same group. 2. Heat exchanger according to claim 1, where the part of the contour of the Small wire fins are polygonal. Including the concave polygon cross-section 3. Heat exchanger according to claim 1, where the axis of the pipe will Defined as a surface with a front and a tail. Each group of tubes is wound in a spiral with two flanges. Which will be intertwined on one corner and in the same direction And spaced from each other to make contact with pipes at different points 4. Heat exchanger according to claim 3, where the adjacent groups of The tubes have fins that are wound in different directions. So that no fins will come in contact with the pipes on the same point. 5. 3 heat exchangers where odd numbered groups have fins that are Wrapped around on the first corner And even numbered groups have fins that are wrapped around at a different angle from the first. 6. 1 heat exchanger where a number of heat transfer tubes will Including the first and second heat transfer pipes Each kit has a heat transfer surface that includes Axis of heat transfer tube The heat transfer surface of each unit is bent at the tube area. To form a zigzag with ridges and grooves The first set will be placed behind the second set. For the ridge of The first set extends into the groove of the second set. Where the heat transfer surface is perpendicular to the direction External fluid flow that flows through the heat transfer surface. Outside of the exchanger tube Change in heat 7. Heat exchanger according to claim 1, where the heat transfer tubes The number one includes the first and second heat transfer pipes. Each set of pipes has a transfer surface. The heat, which includes the axis of the pipe, the set of tubes is arranged so that their faces are parallel, the faces are perpendicular to the direction of the flow of external fluid passing through the outer surface of the tube. Heat exchanger A series of pipes are welded in succession so that Coolant flowing in the pipe Will flow from the first set of pipes The direction of the flow of fluid from the outside through the set of pipes in the middle to the last one installed on the upstream side when Compared with the direction of the external fluid flow 8. Heat exchanger according to claim 1, where the exchanger The heat will be used for air conditioning.
