Definitions

  • This invention relates to a protective wrapping device for shielding a condenser tube of a heat exchanger, more particularly to a protective wrapping device adapted for shielding removably the condenser tube of the heat exchanger which is used in an air conditioning system.
  • a conventional condenser for an air conditioning system is shown to include a zigzag condenser tube 1 for flow of a refrigerant therethrough, and a cooling tower 3 and a water collecting tank 4 which are disposed above and below the tube 1. Water in the cooling tower 3 falls down for removal of heat of the tube 1 and is collected by the collecting tank 4. Then, the water can be pumped into the cooling tower 3 for circulation.
  • the object of the present invention is to provide a protective wrapping device which can be applied to shield a condenser tube of a heat exchanger and which can be removed therefrom for cleaning, thereby prolonging the service life of the condenser tube.
  • the protective wrapping device includes complementary first and second shell walls made of a heat conductive material.
  • the first shell wall has a first major wall portion which is elongated in an axial direction, which extends about an axis in the axial direction so as to be adapted to wrap around a first outer wall half of a condenser tube, and which terminates at two axially extending first edge surfaces that are spaced apart from each other in a transverse direction transverse to the axial direction.
  • the first major wall portion has first outer and inner wall surfaces which respectively extend about the axis and which are opposite to each other, and a plurality of first grooves which are formed in the first outer wall surface and which are spaced apart from each other in the axial direction.
  • Each first groove extends about the axis and towards the two first edge surfaces.
  • the second shell wall has a second major wall portion which is elongated in the axial direction, which extends about the axis so as to be adapted to wrap around a second outer wall half of the condenser tube, and which terminates at two axially extending second edge surfaces that are spaced apart from each other in the transverse direction.
  • Each second edge surface is configured to complementarily mate with a respective one of the first edge surfaces so as to define a receiving chamber between the first and second shell walls for receiving fittingly the condenser tube.
  • the second major wall portion has second outer and inner wall surfaces which respectively extend about the axis and which are opposite to each other, and a plurality of second grooves which are formed in the second outer wall surface and which are spaced apart from each other in the axial direction.
  • Each second groove extends about the axis and towards the second edge surfaces, and is registered with a respective one of the first grooves when the first and second shell walls mate with each other so as to bring the first and second grooves in a looped line.
  • Each of a plurality of tightening members is inserted into a registered pair of the first and second grooves along the looped line to tighten the first and second shell walls to each other so as to secure the first and second shell walls to the condenser tube.
  • the preferred embodiment of the protective wrapping device 100 is shown to comprise at least one shielding member 10 and a plurality of tightening members 20.
  • Each shielding member 10 includes complementary first and second shell walls 11,12 which are made of a heat conductive material, such as aluminum.
  • the first shell wall 11 has a first major wall portion 110 which is elongated in an axial direction, which extends about an axis in the axial direction so as to wrap around a first outer wall half of a condenser tube 200, and which terminates at two axially extending first edge surfaces 115 that are spaced apart from each other in a transverse direction transverse to the axial direction.
  • the first major wall portion 110 has first outer and inner wall surfaces 119, 111 which respectively extend about the axis and which are opposite to each other.
  • a plurality of first grooves 113 are formed in the first outer wall surface 119 and are spaced apart from each other in the axial direction.
  • Each first groove 113 is confined by two protrusions 112, and extends about the axis to reach the two first edge surfaces 115.
  • a plurality of first cutting notches 114 are formed in the first outer wall surface 119 and are disposed transverse to the first grooves 113, respectively.
  • the second shell wall 12 has a second major wall portion 120 which is elongated in the axial direction, which extends about the axis so as to wrap around a second outer wall half of the condenser tube 200, and which terminates at two axially extending second edge surfaces 125 that are spaced apart from each other in the transverse direction.
  • the second major wall portion 120 has second outer and inner wall surfaces 129,121 which respectively extend about the axis and which are opposite to each other.
  • a plurality of second grooves 123 are formed in the second outer wall surface 129 and are spaced apart from each other in the axial direction. Each second groove 123 is confined by two protrusions 122, and extends about the axis to reach the two second edge surfaces 125.
  • a plurality of second cutting notches 124 are formed in the second outer wall surface 129 and are disposed transverse to the second grooves 123, respectively.
  • Each second edge surface 125 is configured to complementarily mate with the respective first edge surface 115 so as to define a receiving chamber between the first and second shell walls 11,12 for receiving fittingly the condenser tube 200.
  • each second groove 123 is registered with the respective first groove 113 so as to bring the corresponding first and second grooves 113,123 in a looped line.
  • Each tightening member 20, in this preferred embodiment, is a plastic tightening band, and is inserted into a registered pair of the first and second grooves 113, 123 to surround the looped line. Two ends of the tightening band 20 can be tied to each other so as to tighten the first and second shell walls 11,12 to each other, thereby securing the same to the condenser tube 200.
  • first and second shell walls 11,12 can be wrapped around the condenser tube 200 for protecting the condenser tube 200 from dust and for heat removal purposes.
  • each first shell wall 11 has a first right end 116 in which one first groove 113 is formed, and a first left end 117 which is provided with a protrusion 118 that extends about the axis to reach the two first edge surfaces 115.
  • the protrusion 118 can be inserted into a corresponding first groove 113 in the first right end 116 of an adjacent first shell wall 11.
  • each second shell wall 12 has a second right end 126 in which one second groove 123 is formed, and a second left end 127 which is provided with a protrusion 128 that extends about the axis to reach the two second edge surfaces 125.
  • the protrusion 128 can be inserted into a corresponding second groove 123 in the second right end 126 of an adjacent second shell wall 12.
  • the first and second edge surfaces 115,125 are inclined from the first and second inner wall surfaces 111,121 toward the first and second outer wall surfaces 119,129, respectively, such that water condensate, which falls down due to gravity, can be prevented from penetrating between the first and second inner wall surfaces 111,121.
  • the tightening bands 20 can be cut by a cutting tool (not shown) extended through the cutting notches 114,124.
  • the first and second shell walls 11,12 can be easily removed and separated from each other.
  • New tightening bands 20 can be used to tighten the first and second shell walls 11,12 once again to each other in order to secure the shell walls 11,12 to the condenser tube 200.
  • an alternative construction of the tightening member 20' is shown to be in the form of a metal C-shaped ring which includes a jaw portion that is insertable into the respective first groove 113.
  • the jaw portion has two jaw ends 21',22' which are biased toward each other in the transverse direction.
  • the jaw ends 21',22' extend respectively beyond the first edge surfaces 115 and abut firmly against the second outer wall surface 129 in the respective second groove 123.
