Definitions

  • the present invention relates to an annular heat exchanger having a plurality of annular heat exchanging units through which different fluids are circulated to make heat exchange with air blown by a centrifugal blower around which the heat exchanging units are arranged.
  • Construction vehicles and machineries are provided with a heat exchanger for cooling different kinds of fluids such as cooling water for cooling the engine, working fluid of hydraulic equipments mounted on the vehicle or machinery, lubricating oil of the engine and so forth.
  • Typical conventional heat exchanger for the purpose described above incorporates a combination of a plurality of heat exchanging units for different fluids and an axial blower.
  • This conventional heat exchanger generates noise of high level to cause annoyance.
  • annular heat exchanger in which annular heat exchanging units are combined with a centrifugal blower.
  • the heat exchanging units are arrayed in the axial direction of the centrifugal blower such that each heat exchanging unit surrounds the centrifugal blower.
  • the US-A-2 171 817 relates to a heat exchanger having an axial flow fan which axially introduces air thereinto and axial discharges it therefrom. Because of this type of the fan, inner and outer heat exchanging units which are disposed concentrically with the axis of the fan and are superposed one over the other are disposed axially adjacent to the fan.
  • the heat exchanging units in the citation are arranged in parallel to the flow of air discharged from the fan, and therefore the heat exchanger would suffer from the drawbacks that the discharged air flows through the heat exchanging units such that a portion of the air flow applies to one of the heat exchanging units and the other portion of the air flow applies to the other heat exchanging units such that, if one of the heat exchanging units is used for the liquid having the highest demand for cooling, the entire air discharged from the blower cannot be utilized for cooling the liquid and the air flow portion applied to the other heat exchanging unit will be discharged out of the heat exchanger as it is even if the air would still have the temperature sufficient to cool the liquid of the highest demand for cooling. Therefore, the arrangement of said prior art could not provide a heat exchanging unit which can operate at high cooling power, nor could provide the heat exchanger having the entire cooling efficiency which is high. Moreover, the heat exchanger using an axial flow fan could not have the size made compact.
  • US-A-2 260 504 discloses a heat exchanger having an axial flow fan and a single heat exchanging unit disposed axially adjacent to the fan.
  • US-A-1 390 899 relates to a heat exchanger having a centrifugal fan and a single heat exchanging unit disposed concentrically with the axis of the fan and arranged to radially surround and cover the fan. Because of the single heat exchanging unit, the heat exchanger has no concern with the problems of cooling different fluids which may have different levels of demand for cooling while improving the entire cooling efficiency.
  • the heat exchanger described therein comprises two or more tank chambers including a tank chamber connected to the fluid inlet of each heat exchanging unit and a tank chamber connected to the fluid outlet of each heat exchanging unit, tubes being connected between said tank chambers and disposed in parallel with the axis of the blower.
  • a heat exchanger comprising a centrifugal blower and a plurality of heat exchanging units for different fluids to be cooled disposed concentrically with the axis of said blower and arranged to radially surround and cover said blower, characterized in that said heat exchanging units are radially superposed one over the other so that the flow of air discharged from the blower passes through the heat exchanging units in series.
  • Fig. 1 is an end view of the known annular heat exchanger
  • Fig. 2 which is a sectional view taken along the line II-II of Fig. 1.
  • a heat exchanger of the prior art has sector columnar tank chambers 1 to 4.
  • the tank chambers 1 and 4 are separated from each other by a partition wall 5, while the tank chambers 2 and 3 are separated from each other by a partition wall 6.
  • the tank chambers 1 and 2 are provided with inlet pipes 7 and 8, respectively, while the tank chambers 3 and 4 are provided with outlet pipes 9 and 10, respectively.
  • a cap 11 is provided on the tank chamber 1.
  • the tank chambers 1 and 3 are connected to each other by annular tubes 12.
  • the tank chambers 2 and 4 are connected to each other by annular tubes 13.
  • Fin plates 14 are attached to the annular tubes 12, 13 and are arranged radially.
  • the annular tubes 12 and the fin plates 14 in combination constitute a first heat exchanging unit 15 while the annular tubes 13 in co-operation with the fin plates 14 constitute a second heat exchanging unit 16.
  • the first and the second heat exchanging units 15 and 16 are arrayed in the axial direction.
  • Side walls 17 and 18 are secured by means of bolts 19 to both sides of the tank chambers 1 to 4.
  • a reference numeral 20 designates a shaft extending through the side wall 17 and connected to a prime mover (not shown).
  • a seal member 21 is secured to the side wall 17 to provide a seal between the shaft 20 and the side wall 17.
  • the shaft 20 is connected at its other end to a centrifugal blower 22 which is surrounded by the heat exchanging units 15 and 16.
  • a reference numeral 23 denotes a bell mouth provided in the side wall 18.
  • annular heat exchanger two kinds of liquids are circulated through respective heat exchanging units 15, 16 to make heat exchange with air which is blown by the centrifugal blower 22 driven by the prime mover through the shaft 20.
  • a first and a second fluids to be cooled is supplied into the tank chambers 1 and 2 through the inlet pipes 7 and 8, respectively.
  • the fluids then flow toward the tank chambers 3 and 4 through respective annular tubes 12 and 13, so that the heat possessed by the fluids are radiated from the plate fins 14 attached to the annular tubes 12 and 13.
  • the cooling air is induced through the bell mouth 23 and is deflected orthogonally toward the heat exchanging units 15, 16 to flow through the latter. Therefore, the velocity of air flowing through the axial end portion adjacent to the side wall 18 is smaller than that flowing through the axial end adjacent to the sidewall 17. Namely, since the cooling air flows through the heat exchanging units 15, 16 at different velocities, it is not possible to equalize the cooling efficiencies of both heat exchanging units. In addition, each of the heat exchanging units 15 and 16 cannot receive whole part of the air induced through the bell mouth 23.
  • the heat exchanger has three or more heat exchanging units, it is not possible to arrange the inlet pipe and outlet pipe of the central heat exchanging unit in parallel with the shaft 20, unless the tank chamber of the central heat exchanging unit solely is projected radially outwardly or the inlet and outlet pipes are bent at 90°. In such a case, the maximum diameter of the annular heat exchanger is increased impractically.
  • the present invention provides an annular heat exchanger in which the cooling efficiencies of all heat exchanging units are equalized and the heat radiation efficiency of each heat exchanging unit is improved, without being accompanied by an increase of the maximum outside diameter of the annular heat exchanging unit, as will be understood from the following description of the preferred embodiments.

  • tank chambers 24 and 27 are constructed as a unit and are separated from each other by a partition wall.
  • the tank chambers 25 and 26 may be constructed as a unit and separated from each other by a partition wall.
  • Numerals 28 and 29 denote inlet pipes connected to the tank chambers 24, 25, while numerals 30 and 31 denote outlet pipes connected to the tank chambers 26, 27.
  • the tank chamber 24 is provided with a cap 32.
  • the tank chamber 24 and the tank chamber 26 are connected to each other by annular tubes 33, while the tank chambers 25 and 27 are connected to each other by annular tubes 34.
  • Fin plates 35 and 36 are attached to annular tubes 33 and 34 and are disposed radially.
  • the annular tubes 33 and the plate fins 35 in combination constitute a first heat exchanging unit 37, while a second heat exchanging unit .38 is constituted by annular tubes 34 and the fin plates 36.

  • the tank chambers 39 and 41 are connected to each other through straight tubes 48, while the tank chambers 40 and 42 are connected to each other by means of straight pipes 49.
  • Annular plate fins 50 and 51 are attached to the straight tubes 48, 49.
  • the straight tubes 48 and the plate fins 50 in combination constitute a first annular heat exchanging unit 52, while the straight tubes 49 and the plate fins 51 constitute a second heat exchanging unit 53.
  • the heat exchanging units 52 and 53 are arranged concentrically with each other.
  • Fig. 9 illustrates a still another embodiment of the invention while Fig. 10 is a sectional view taken along the line X-X of Fig. 9.
  • the heat exchanger of this embodiment has about semicircular columnar tank chambers 54 to 57 and circular columnar tank chambers 58, 59.
  • Inlet pipes 60 and 61 are connected to the tank chambers 54, 55, respectively, while outlet pipes 62, 63 are connected to the tank chambers 56, 57.
