Description

201111729. VI. Description of the Invention · Technical Field of the Invention The present invention relates to a heat exchanger for exchanging heat with a fluid circulating in a pipe, and more particularly, it relates to a flow by A heat exchanger in which multiple tubes are circulated and heat exchange is performed efficiently. [Prior Art], °° Previously, as a heat exchanger, for example, a heat exchanger having a micro-channel structure as shown in Fig. 13 is known as Fig. 13, and the symbol 7 is a thin plate. The plate has a plurality of cleaved grooves 70 formed on the surface thereof. The plate 7 has a plurality of sheets having the same structure in the vertical direction. In this case, the upper and lower grooves 7 are arranged alternately and orthogonally. When the heating fluid A is cooled using the microchannels thus laminated, the heating fluid A is caused to flow into the grooves 70 arranged in either direction, and the fluid B having a temperature lower than that of the heating fluid A is orthogonal thereto. The tanks of the upper and lower layers are circulated, whereby the fluid A is cooled by depriving the heat by the fluid B flowing in the upper and lower layers of the fluid A. Further, in addition to the structure shown in Fig. 13, a structure in which a cooling medium flows through the outer peripheral portion of the tubular flow path to cool the heating fluid is known. For example, Patent Document 1 to Patent Document 4 and the like disclose a heat exchanger 83 having a multiple tube as shown in Fig. 14 . The heat exchanger 83 is provided with an inner tube 85 coaxially inside the outer tube 84 to exchange heat between the fluid flowing through the inner tube and the fluid flowing between the outer tube 84. Further, as such a multi-tube, for example, a multi-tube in which a short-shaped fin of the 201111729 is provided in the inner tube is known, and a spiral turn is known between the inner tube and the outer tube. Multiple tubes of sheets, etc. (Patent Document 1 to Patent Document 3, etc.). When such a coaxial tube is used to cool the heating fluid, the heating fluid is circulated in the inner tube 85, and the cooling fluid is circulated in the gap with the outer tube 84, whereby heating is performed from the outer circumference of the inner tube 85. The fluid is cooled. CITATION LIST Patent Literature Patent Literature 1: Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei.

That is, when the microchannel having the positive AC path as shown in FIG. 13 is observed from the axial direction of the groove 70, as shown in FIG. 15, it can be between the upper and lower fluids orthogonal to the groove 70a through which the heating fluid flows. Although heat exchange is performed, since a heating fluid of the same temperature flows from a flow path parallel to the flow path through which the heating fluid flows, there is a disadvantage that heat exchange cannot be performed. That is, in the upper and lower layers of the groove 7〇a in Fig. 15, a fluid having a relatively low temperature (shown as "Low" is shown as "L") flows, and the fluid of the groove 70a can be made by the fluid. Although it is cooled, since the temperature of the fluid adjacent to this tank 7〇a is high (it is shown by the high (High), it is shown as rH"), there exists a problem that it cannot carry out the cooling by the fluid of this "Η". On the other hand, in the multi-tube type heat exchanger shown in FIG. 14, it is possible to use 201111729. In the heating flow, the heating fluid is cooled outside the inner tube, so that the heat efficiency can be changed. . However, in such a coaxial tube, it is necessary to thicken the inner tube in consideration of the flow of a large amount of fluid, but if so, the thick inner tube will only be able to exchange heat on the outer surface of the inner tube due to exchange efficiency. Will get worse. That is, if the inner tube is thickened, there is a disadvantage that the heating fluid can be cooled only in the vicinity of the surface of the watch. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a heat exchanger which can efficiently perform heat exchange even when a plurality of tubes are used.

In addition, it is assumed that the same reference numerals as in the first embodiment have the same configuration as the first embodiment. As shown in FIGS. 5 and 6, the heat exchanger 1 of the second embodiment passes the first fluid U from the first inflow portion 12 through the small tube and bypasses the second between the heat transfer tubes 4 arranged in a line. The inflow portion 24 flows to the outer peripheral heat exchange chamber 38 which is the outer gap of the outer tube c. As shown in Fig. 6, the heat transfer pipe 4 of the second embodiment has a plurality of (two in the drawings) inner tubes connected to the inner side of the circular outer portion 42 in the same manner as in the first embodiment. The inner tube 41 is formed by coming out from the outer tube 42 and the mountain. And, the two-way extension-inflow portion 12' of the extended inner tube 41 is also connected to the other end portion, and the first portion is connected to the first portion, and the first inflow portion 12 or the first discharge portion 3 = ^. This member forms a confined space. Q is independent and, for the end of the outer tube 42, an independent first inflow portion 15 201111729 22 is provided and connected to the end portion 'the second fluid 21 flows from the end portion into the outer tube 42 and the gap of the inner portion 41 . Further, for the end of the outer tube 42 on the opposite side, a separate second discharge portion 25 is also provided and connected to the end portion, so that the second fluid 21 is discharged from the end portion. Here, in the case where the fluid is caused to flow into/out of the first inflow portion 12 or the first discharge portion 15, and the second inflow portion 22 or the second discharge portion 25, the inflow connection portion 14 is connected to the inflow.

That is, if you use a heat exchanger for cooling and heating! Alternately, as shown in Fig. 7, when the second fluid 21 is cooled by the gap portion of a heat pipe (the heat conduction S in the center of the figure), the second pipe 21 can be cooled from the inner pipe to the second. The button 21 is cooled, and the adjacent heat exchanger 1 side is cooled by the cold second fluid 21 moving in the closed portion W of the heat transfer pipe 4. <Third Embodiment> Next, an application example of the third embodiment will be described. When the heat transfer pipe 4 is attached to the first inflow portion 12 (first discharge portion 15) and the second inflow portion 22 (second discharge portion 25) as in the above-described first embodiment, it is necessary to be in each inflow portion or discharge portion. The insertion hole i_ for passing the outer tube 42 or the inner tube 41 is troublesome. In particular, for the inner tube 41, since the outer tube 42 is covered by the outer tube 42, the insertion operation is more difficult. Therefore, in the second embodiment, the inner tube 41 or the outer tube 42 is simply attached to each header without performing the insertion work. 17 201111729 The structure of the inflow portion or the discharge portion of the present embodiment will be described with reference to Fig. 8f, but the first inflow portion 12 and the first discharge portion 15' of the heat exchanger 1 and the second flow person are described. The portion 22 and the second discharge portion 25 will be described in the same configuration.

An open opening 77. The first wall surface 73 is divided by a surface parallel to the axial surface of the heat transfer pipe 4. A plurality of first concave portions 78a are formed on the divided surface. The first recessed portion 78a has a shape in which the outer shape of the outer tube 42 is divided into a half by a surface parallel to the axial surface of the heat transfer tube 4 (in the present embodiment, the lower half of the outer tube 42 is divided into a semicircle of half). shape). The first concave portion 78a having such a shape formed by the boring tool is symmetrical with respect to the first wall portion on the first wall surface, whereby even when the unit separation body 逆 is reversed and the respective first concave portions 78a face each other, Each of the first recesses 78a is used to sandwich the circular outer tube 42. On the other hand, on the second wall surface (the rear surface 76) facing the magical direction of the outer tube with respect to the first wall surface 73, a second concave portion having a semicircular shape in which the outer shape of the 41 is divided into half is also formed. 7 places. The dividing surface of the second concave portion 78b is formed by the eight-chamber surface of the first wall surface 73. 201111729

The L &amp; 9 is placed in the opposite direction of the unit separation body 72, and the first recessed portion 78a is sandwiched between the outer peripheral portion of the outer tube 42 and the second recessed portion is inserted into the manifold 41. Thereby, the fluid flows from the inside of the header unit 71 to the gap between the outer s 42 and the inner tube 41.

Similarly, the recesses are reversely opposed to each other and sandwiched by the third recess 78c. 41. Here, the pair of unit splits 72 constitute the second inflow 22, etc., but may also surround all of the inner portions. A header cover at the end of the tube 41 constitutes the second inflow portion 22 and the like. As shown in Fig. 10, the official cover 8 is provided with a discharge port 82 through which the fluid inflow 81f allows the fluid to be discharged, so that it covers the outer periphery of the laminated header = 71, and is in the header unit. The opening portion of the opening portion 71 is attached to the gap portion S, and the fluid flows in and out of the heat transfer tube 4 through the opening portion 77 of the tube unit 71. ^ If so, even if When the heat-conducting member 4 composed of the inner tube 41 and the outer tube 42 is installed, it is not necessary to be aligned with the insertion hole and inserted into the heat-transfer tube 4 as before, and the heat-transfer tube 4 can be installed extremely efficiently. Further, the present invention is not limited thereto. The above embodiment can be implemented in various states. For example, in the above-described embodiment, a heated fluid is used as the second fluid 21, and the first fluid 11 or the third fluid 31, which is a cold fluid, is used.
