  • the thermal transfer unit functions to cool said thermal fluid. However, if the thermal fluid of the circulation system of said other equipment is at a temperature lower than that of ambient air, then the thermal transfer unit functions to heat said thermal fluid.
  • This invention relates to thermal transfer units of the type usable to cool or heat thermal fluids from other equipment.
  • the primary object of the instant invention is to provide a thermal transfer unit for thermal fluids from the cooling or heating fluid circulation systems of other equipment employing ambient air as the cooling or heating medium as the case may be, which heat transfer unit incorporates a pump and thermal transfer elements wherein the said thermal transfer elements are formed and oriented to increase their own effectiveness by providing circulation of ambient air thereover; the said ambient air may *be at ambient temperatures or it may be cooled or heated to meet the requirement of particular installations.
  • FIG.1 is a longitudinal elevational view of a thermal transfer unit embodying the invention.
  • FIG/2 is a longitudinal sectional view taken on the line 22 of FIG. 3.
  • FIG. 3 is an end elevational view taken from the left hand end of FIGS. 1 and 2.
  • FIG. 4 is a cross sectional view taken substantially on the line 4-4 of FIG. 2.
  • the embodiment of the thermal transfer unit 10 of the invention disclosed for illustrative purposes consists in general of a fixed or stationary mounting member 11 having an inlet 12 from and an outlet 13 to a thermal circulating system outlet and inlet 141 respectively of other equipment 14 such as, for example, but not limiting, engines, chemical process elements, machine tools, reactors, or other equipment requiring either the cooling or heating of fluids therefrom or from the thermal fluid of the cooling or heating system thereof.
  • equipment 14 such as, for example, but not limiting, engines, chemical process elements, machine tools, reactors, or other equipment requiring either the cooling or heating of fluids therefrom or from the thermal fluid of the cooling or heating system thereof.
  • the invention will be described as a thermal transfer unit for the cooling of thermal fluid of the cooling circulation system of any type of other equipment 14; however, it is obvious that the use of thermal transfer units of the invention need not be so limited.
  • ambient air at normal ambient air temperatures generally will be employed to cool thermal fluid from the said other equipment 14; however, pre-cooled ambient air or pre-heated ambient air may be employed when and as it is required to cool or heat the thermal fluid from other equipment 14.
  • the fixed or stationary mounting member 11 may he of any suitable design or detail.
  • the particular mounting member 11 shown in the drawings consists of a flange 15 having an integrally formed central hollow collar 16 extending therefrom into which is fixed a central shaft 17 extending axially outwardly from said hollow collar 16.
  • the said flange 15 of the stationary mounting member 11 abuts a complementary flange 142 of a housing 143 of said other equipment 14 with a gasket 18 therebetween, and is preferably secured to said flange 142 of said other equipment 14 by suitable studs 151.
  • the said thermal transfer assembly 20 is the rotating element of the thermal transfer unit 10 and broadly consists of a pump element 21 including an annular pump chamber 22, an annular cooled thermal fluid collection chamber 23, and a plurality of axially extending annularly arranged thermal transfer elements 24.
  • Each said thermal transfer element 24 has a U-shaped passage 240 therein which is connected at one end to and communicating with said annular pump element 21 preferably adjacent the outer periphery thereof, and the other end of said U-shaped passage 240 is connected to and communicates with the said annular cooled fluid collection chamber 23.
  • the said thermal transfer elements 24 are suitably finned at 241 whereby to provide effective thermal transfer from thermal fluid passing therethrough to ambient air.
  • the said pump element 21 is annularly formed to provide an annular pump chamber 22 having suitable passages 210 thereinto from the inlets 12 of the mounting member 11.
  • the pump element 21 is annularly formed with its annular pump chamber 22 defined by an annular outer wall 211 and end members 212 and 213, and rotates around the fixed central shaft 17 as an element of the thermal transfer assembly 20.
  • the said fixed central shaft 17 which extends axially outwardly from the central annular collar 16 of the mounting member 11 serves as the inner annular wall of the said pump element 21.
  • bafiies 216 Adjacent the radially spaced inner ends of each of the fixed vanes 214 of the pump element 21, but spaced in offset relationship thereto, are bafiies 216 radially extending from the said fixed central shaft 17. These battles 216 are preferably employed to interrupt the tendency for free flow of thermal fluid around the fixed central shaft 17 between the free inner ends of the fixed vanes 214 forming the pump sub-chambers 215 as the thermal transfer assembly 21), including the pump element 21, is rotated with respect to the said fixed central shaft 17. While the hereinbefore described type of pump element 21 is preferred, it is obvious that other pump means preferably forming a part of the thermal transfer assembly 20 may be employed.
  • the said fluid transfer assembly 20 is rotatably mounted on the fixed central shaft 17 extending axially outwardly from the central collar 16 of the said mounting member, preferably employing a suitable ball bearing 25 as anti-friction means.

  • the outer end of the said shaft extension 170 is supported preferably in a combine-d thrust and radial bearing 26 where the said outer end of the said shaft extension 170 is supported on a suitable supporting arm or the like 27 as best shown in FIG. 2.
  • a suitable annular thrust bearing plate 28 is disposed around the collar 16 of the mounting member 11 between the flange of the said mounting member 11 and an annular bearing face 29 provided on the inner end of an axially inwardly disposed annular hub 30 formed on the said thermal transfer assembly 20.
  • Suitable fiuid seals 202 are provided between the rotatably mounted fluid transfer assembly and the fixed mounting member 11 and its fixed central shaft 17.
  • the said fluid transfer assembly may be rotated by any suitable means, not shown, which may employ a V-belt drive having a V-belt 200 running over a V-belt pulley 201 formed integral with the outer wall of the annular pump element 21.
