Description
- This Application is a Continuation application of International Application PCT/RU2012/001122, filed on Dec. 27, 2012, which in turn claims priority to Russian Patent Applications No. RU2012105559, filed Feb. 17, 2012, both of which are incorporated herein by reference in their entirety.
- The claimed heat exchanging device is a device that can be used for thermal and cool treatment of media, namely, liquids, gases, suspensions and slurries.
- It is known a multi-channel heat exchanging apparatus, comprising a package of at least three pipes arranged coaxially to form annular channels, two installed toward each other collector rings with outer coaxial stepped cylindrical surfaces, introduced into the channels and contacting with their walls, wherein each of the collectors has two longitudinal deaf channels communicated with the respective annular grooved channels (Patent of the Russian Federation No. 54731, IPC 6 F 28
D 7/10). - Disadvantage of this construction is the complexity of manufacture, as it consists of a large number of parts, as well as insufficient contact with the surface of heat exchanging device, which reduces the heat exchange efficiency.
- There are heat transfer tubes that have inserts in the form of longitudinal ribs in the central part and radial transversal ribs on the outer surface of the heat transfer tube (See U.S. Pat. No. 4,031,602, IPC F28F 11/00, published on 28 Jun. 1977). The shape of the insert increases the area of the inner surface of the tube, as well as heat transfer characteristics designed to increase the efficiency of heat transfer, i.e. increases the heat transfer performance of the tube.
- These heat exchange tubes have fewer parts than the previous analogue, but still are complicated to manufacture.
- The most similar technical essence has the “Heat exchanger for fuel heating device” made by extrusion, comprising a tubular round shaped body and numerous radial branches inside and outside. At that there are much more internal branches than the external ones. The branches are located at a certain equal distance from each other (see U.S. Pat. No. 4,657,074, IPC F28F 1/42, published 19 Feb. 1986). Selected by the authors as the closest analogue). Such heat exchanger is also complicated to manufacture.
- The device is intended to increase the area of contact of medium with the heat exchanging device, increase the amount of cooled or heated medium, decrease the operating costs and provide manufacturing simplicity.
- The proposed heat exchanging device is made in the form of profile product manufactured by extrusion that comprises pushing high viscosity material through a profiling tool and molding this product with formation of specified forms. The profile product is made of a ductile metal such as aluminum.
- The problem is solved by the fact that the heat exchanging device is designed as follows. It consists of a single part made by extrusion in the form of a tubular body with external and internal radial branches, at that the tubular body in a circumferential direction has identical longitudinal round holes, and on the outer surface of the tubular body there is at least one mount. Internal and external radial branches taper from the base to the edge of branches and are made sinusoidal with constant step and amplitude in one of the solutions. They can be made of the same width from the base to the edge of branches. The sinusoids of external radial branches can be made with variable amplitude and step from the base to the edge of branches. The external radial sinusoidal branches can be made of different length relative to each other and at different distances from each other. The external and internal radial branches can be made with complementary undulating projections. The longitudinal round holes are made along the entire circumference of the tubular body at equal distances from each other. On the walls of the longitudinal round holes additional radial undulating projections directed inside the holes can be made. The mounts can be made in the form of projections with round bulge on the top and different length and may be located in different places on the outer surface of the tubular body. The height of radial branches made on the outer surface of the tubular body can be equal to zero. Simultaneously in the heat exchanging apparatus two or more devices can be used.
- The specified location and specified length of radial sinusoidal external and internal branches provide the maximum necessary contact with the surface of the heat exchanging device and medium moving inside and heat exchange medium or coolant moving outside. At that the heat exchanging device can be used to move various media that require cooling or heating over a long distance.

- FIG. 10—view of eight heat exchanging devices with radial, sinusoidal branches of different length in relation to each other, fixed in the round case.
- FIG. 11—heat exchanging device with external radial branches equal to zero.
- The heat exchanging device consists of one piece 1 (
FIG. 1 ). It is made by extrusion. The device hastechnological gaps 2 and 3, which are subsequently welded (FIG. 2 ). The heat exchanging device is made as atubular body 4 with the external 5 and internal 6 radial branches. The geometry of the radial external 5 and internal 6 branches is determined by calculation, depending of the thermal balance of the specified device. The tubular body in a circumferential direction has identical longitudinal round holes 7 (FIG. 3 ). The device is designed to be mounted inside thecase 8 and is fixed inside thecase 8 in theprotruding parts 9 withapertures 10 by means of a fastener located on the external surface of the tubular body. The fastener is made in the form ofprojections 11 at the edges 12 (FIG. 4 ). The fastener can be of different length and is made in various places on the external surface of the tubular body (FIG. 11 ). The number of fasteners is chosen by calculation and depends on the type of the case in which the heat exchanging device is used. The device provides for the passage through the heat exchanging apparatus at least three media, for example,cooling medium 13, operating media that require cooling 14 and 15, orheat carrier 13, operating media that requireheating medium 13 and can be different in various formed channels. Internalradial branches 6 and externalradial branches 5 can be made tapered from the base to the edge of branches. They can be made sinusoidal with aconstant step 16 andamplitude 17. They can have the same width from the base to the edge ofbranches 18. The heat exchanging device can be installed in the round case 8 (FIG. 3 ) or in the square case (FIG. 5 ). The sinusoids of externalradial branches 5 can be made with variable amplitude and step form the base to the edge of branches. The external radial sinusoidal branches can be made ofdifferent length 19 relative to each other and at different distances from each other, for example, in the heat exchange device fixed secured in a square case (FIG. 6 ). The externalradial branches 5 and internalradial branches 6 can be made with complementaryundulating projections FIG. 7 , 8). The longitudinal round holes 15 are made along the entire circumference of the tubular body at equal distances from each other. On the walls of the longitudinal round holes 15 additional radialundulating projections 22 directed inside theholes 15 in order to increase the area of contact of media with the heat exchanging device can be made. The height of radialexternal branches 5 made on the outer surface of the tubular body can be equal to zero (FIG. 11 ). Simultaneously two or more devices can be used. For example, four heat exchanging devices with external sinusoidalradial branches 5 of different length in relation to each other, fixed in the square case (FIG. 9 ), or eight heat exchanging devices with external sinusoidalradial branches 5 of different length in relation to each other, fixed in the round case (FIG. 10 ). - Depending on the length of the heat exchanging device, the media can be moved over long distances.
- The heat exchanging device is manufactured, for example, of aluminum by extrusion, consisting in constant pushing of melted high viscosity material through a forming tool—drawing nozzle, in order to obtain the product with a desired cross-sectional form.
- The device operates as follows.
- The heat exchanging device is installed in the
case 8 and fixed byfastener radial branches 5 of the device cools or heats them throughout their length. The cooling or heating taken by the outer walls of the externalradial branches 5 of the device is passed to the inner walls of the internalradial branches 6 of the device. Being heated or cooled the inner walls of the internalradial branches 6 of the device transfer cold or heat tomedia - The design of the heat exchanging device is simple, economical and effective due to the increased amount of cooled or heated media and increased area of contact of media with the heat exchanging device. The product is made as a single piece, which simplifies the assembly of the heat exchanging device and results in a reduction of operating costs.
- Thus, the formulated problem is solved.
