Definitions

  • the cooling system comprises a pair of axially spaced fans, defining a chamber means therebetween, adapted to be rotated by drive means operatively connected thereto.
  • At least one fluid cooling means such as an air-cooled radiator, extends transversely between the two fan means to define one side of the chamber means whereby compressed air pumped into the chamber means will exit through the radiator.
  • a baffle plate is positioned between the two fan means to induce substantially uniform and non-turbulent air flow therethrough.
  • the cooling system is preferably mounted on the rearward end of a vehicle, such as a track-type loader, to aid in impelling dust laterally away from the vehicle during operation thereof.
  • FIG. 1 is a side elevational view of a track-type loader having the cooling system of this invention mounted on a rearward end thereof;
  • FIG. 2 is an enlarged, sectional view of the cooling system, taken in the direction of arrows 11- in FIG. 1;
  • FIG. 3 is an enlarged section of a fan blade depicting the chordal angle thereof.
  • FIG. 1 illustrates a track-type loader comprising a standard bucket arrangement 11 movably mounted on a forward end thereof.
  • the loader further comprises an operators station 12 and is mounted for movement on a pair of laterally spaced endless track assemblies 13 (one shown), driven by an engine 14.
  • the engine is adapted to selectively rotate a pair of drive sprockets 15 (one shown) via an intermediate drive train, including a transmission 16.
  • a cooling system 17 of this invention is mounted on a rearward end of the loader, preferably above transmission 16.
  • the cooling system comprises a pair of axially spaced first and second fan means 18 and 19 secured to opposite ends of a common drive shaft 20 of a drive means, further including a pair of drive belts 21 driven by a power take-off from engine 14.
  • the drive shaft is preferably disposed on the longitudinal axis of the loader and is rotatably mounted on bracing means, such as cross-braces 22 and 23 secured to the loaders main frame, by bearing means 24 and 25, respectively.
  • a first corner bracket 29 is secured to adjacent ends of cross-brace 22, radiator 26 and oil cooler 28.
  • cross-brace 22 is likewise secured to adjacent ends of radiator 27 and oil cooler 28 by a second corner bracket 30.
  • the forward ends of radiators 26 and 27 are secured to opposite ends of crossbrace 23 by third and fourth brackets 31 and 32, respectively.
  • Each of the four brackets is attached to the frame of the vehicle by releasable fastening means, such as bolts 33.
  • a baffle means or plate 34 detachably mounted between radiators 26 and 27, is preferably positioned intermediate first and second fan means 18 and 19 and in at least general parallel relationship therewith. It should be noted that an air-receiving chamber means, defined on three sides by cooling means 26, 27 and 28, is thus separated into first and second chambers 35 and 36 by the baffle plate which has a suitably sized aperture 37 formed therethrough to accommodate drive shaft 20.
  • the cooling system preferably further comprises a protective enclosure, including mesh screens or grills 38, 39 and 40, suitably integrated therein to facilitate unimpeded air flow therethrough.
  • fan means 18 and 19 function to pump air into chambers 35 and 36, respectively.
  • the area forward of fan 19 is open to ambient to insure a sufficient air supply thereto.
  • the air is compressed in the chambers and flows substantially uniformly through the cores of radiators 26 and 27 at a substantially increased pressure and density.
  • the noise level of the cooling system is held to an acceptable low level in that baffle plate 34 functions to deter undue air turbulence by inducing uniform air flow through the chambers.
  • the air pressure in chambers 35 and 36 may be uniformly balanced by providing different chordal angles for two or more blades 41 employed on fan means 18 and 19.
  • a first chordal angle a for the blades of fan means 18 may approximate 27 whereas a second and lesser chordal angle for the blades of forwardly disposed fan means 19 may approximate 24.
  • the two such fan means were found to circulate air at approximately I 1,800 cfm through the system, when rotated at 600 rpm, to provide the required cooling desiderata.
  • the present cooling module affords an additional advantage in that service can be accomplished without disturbing sound suppressing material now used to protectively line most operators stations. Such material must be carefully placed to seal all openings or avenues for possible transfer of noise toward the operator. It is for this reason forwardly disposed, relatively remote screens or grills 43 are provided for introducing cooling air at the forward end of the module.
  • a cooling system mounted on a frame, comprising a pair of axially spaced and rotatable first and second fan means for pumping air into chamber means defined therebetween,
  • baffle means comprised of a single plate disposed within said chamber
  • said drive means comprising a drive shaft extending through said baffle means and connected at opposite ends thereof to said first and second fan means,
  • first fluid cooling means extending traversely between said first and second fan means to define a first side of said chamber means whereby air pumped into said chamber means will exit through said first fluid cooling means
  • a second fluid cooling means extending traversely between said first and second fan means in at least generally parallel and laterally spaced relationship relative to said first fluid cooling means to define a second side of said chamber means
  • each of said first and second fan means comprising a plurality of fan blades, a first chordal angle of the fan blades of said first fan means being greater than a second chordal angle of the fan blades of said second fan means.
  • each of said first and second fluid cooling means constitutes a radiator.
  • the cooling system of claim 1 further comprising a pair of axially spaced first and second bracing means detachably connected to a support and extending traversely between and connected to said first and second fluid cooling means.
  • the cooling system of claim 4 further comprising a bracket secured to each end of each of said first and second fluid cooling means and further secured to each of said first and second bracing means, each of said brackets removably attached to said support by releasable fastening means.
  • baffle means extends transversely between and connects to said first and second fluid cooling means to separate said chamber means into first and second chambers.
