HEAT EXCHANGER APPARATUS Filed Dec. 2, 1963 2 Sheets-Sheet 2 INVENTORS DONALD ANDREW HURTER GUNNAR GEORGE KARLSON RICHARD FRANCIS TALLINI ATT RNEY United States Patent 3,229,760 HEAT EXCHANGER APPARATUS Donald Andrew Hurter, Nor-wood, Gunnar George Karlson, Belmont, and Richard Francis Tallini, Sudbury,
Mass., assignors to Standard-Thomson Corporation,
Waltham, Mass, a corporation of Delaware Filed Dec. 2, 1963, Ser. No. 327,395 2 Claims. (Cl. 165-134) This invention relates to heat exchanger apparatus. The invention relates more particularly to radiator structure provided with cooling fins which are relatively easily damaged and means for protection thereof.
Radiator structures or heat exchangers normally comprise a plurality of fluid conduit members to which are firmly joined a multiplicity of fins or the like. Thus, heat from the conduit members readily flows into the fins.
Thus, air or other gas, at a lower temperature than the fins, cools the fins as the air engages the fins and receives heat therefrom. Thus, the conduit members are cooled and the fluid within the conduit members is cooled.
Radiator structures are used with many types of apparatus. Radiator or heat exchanger apparatus which is used in aircraft frequently has the fins thereof damaged by hail impingement if the aircraft encounters a hail storm. Also, in the use of radiators with various types of vehicles, stones or the like frequently strike the fins and cause damage thereto.
Attempts have been made to protect the fins. One method has been that of disposing bars or rods in the form of a grid or the like in front of the fins so that hail or stones or other objects will strike the bars or rods rather than the fins. However, it has been found that radiator structure which is so provided with bars or rods for protection of the fins thereof frequently becomes clogged with ice or snow when ambient temperatures are freezing temperatures. Icing conditions therefore result in blocking or restricting of airflow through the radiator. When such conditions exist, the proper amount of air does not flow through the radiator or heat exchanger.
Thus, it is an object of this invention to provide radiator or heat exchange structure which has protective means which prevents damage by hail or stones or the like and which protective means does not permit or cause blocking of airflow by ice or snow or the like.
Other objects and advantages reside in the construction of parts, the combination thereof, the method of manufacture and the mode of operation, as will become more apparent from the following description.
In the drawing:
FIGURE 1 is a perspective view of heat exchanger apparatus of this invention.
FIGURE 2 is an exploded perspective view of the apparatus of this invention.
FIGURE 3 is an enlarged fragmentary perspective view showing cooling fins and protective means therefor of the apparatus of this invention.
FIGURE 4 is an enlarged fragmentary perspective view showing protective means of the apparatus of this invention.
FIGURE 5 is a fragmentary enlarged perspective view of a modification of heat exchanger apparatus of this in- "ice disposed intermediate each pair of the pans 11 and are firmly secured thereto in good thermal conductive relationship therewith. Thus, the fins 12 receive heat from the fluid within the pans or tubes 11, as the pans or tubes 11 are heated by the fluid therewithin. Therefore, air or other gas which is lower in temperature than the fluid within the pans 11 and passing in engagement with the fins 12 receives heat from the fins 12.
A main inlet conduit 14 and a main outlet conduit 16 connect to or are in communication with the tubes or pans 11 so that fluid entering the inlet conduit 14 flows through the pans 11 and out through the outlet conduit 16.
The fins 12 are readily damaged if struck by objects such as hail or stone or the like.
A guard structure 20 of this invention protects the fins 1-2, as shown in FIGURE 2. The guard structure 20 comprises a frame or housing 22 within which are a plurality of protective fluid conductor members 24 which are larger and are of much stronger construction than the fins 12. The protective fluid conductor members 24 are shown herein in the form of strips which are preferably shaped in a wave formation as shown, but may be of any other desired shape or formation disposed in front of the fins 12. If desired, retainer rods 25 may be carried by the frame 22 between opposing side portions thereof.
The guard structure 20 has an inlet conduit 26 which connects to the main inlet conduit 14 so that a portion of the fluid flowing into the main inlet conduit 14 flows through the protective conductor members 24, rather than through the tubes or pans 11.
The guard structure 20 also has an outlet conduit 28 which is connected to the main outlet conduit 16 so that fluid flowing from the conductor members 24 flows outwardly through the conduit 28 and into the main outlet conduit 16. The strip conductor members 24 are thus joined to the conduit members 11 through the inlet conduit 26 and outlet conduit 28.
It is to be understood, however, that any suitable desired arrangement of inlet and outlet conduits and connections for the pans 12 and for the protective conductor members 24 may be employed. The protective conductor members 24 do not need to be joined to the conduit members 14 and 16 and the fluid flowing through the protective conductor members does not need to be a portion of the fluid which would otherwise flow through the fins 12.
Due to the fact that fluid which flows through the protective conductor members 24 is warmer than ambient temperatures, it is not possible for clogging conditions caused by ice or snow among the protective conductor members to occur. Any ice or snow becoming disposed among the protective conduct-or members 24 is melted by the heat of the fluid therewithin. Therefore, the protective conductor members 24 guard the fins 12 against damage by impingement thereupon without the possibility of adverse effects which might otherwise be caused by icing action.
FIGURES 5 and 6 show a modification of the heat exchanger apparatus of this invention. Conduit tube or pan members 50 extend beyond fin members 52. In other words, the front wall of the fin members 52 is recessed rearwardly from the leading edges of the conduit tubes or pan members 50. As stated above, the fin members 52 are secured to the conduit pan members 50 so that there is good thermal conductivity therebetween. Herein two rows or layers of fin members 52 are shown between two pans or tubes 54. A thin heat conductive sheet or strip 53 is shown between the two rows or layers of fin members 52 and attached thereto.
A solid protective strip 54 is disposed between each.
pair of adjacent fluid conduit pans 50. Each strip is shown as being in a wave shape and is firmly attached to the pans 50 which it engages so that there is good thermal conductivity therebetween.
The protective strips 54 are disposed in front of the fins 52 so as to protect the fins against damage from impingement by moving objects such as hail or stones or the like.
As warm fluid flows through the conduit tubes or pans 54 the fluid heats the pans 54. Heat from the pans 54 flows into the fins 52 and heat from the fins 52 flows into the air or gas which moves over the fins 52.
Due to the fact that the protective strips 54 are firmly secured to the pans 50, heat from the pans 50 also flows into the protective strips 54. Thus, the protective strips 54 are warmer than the ambient air or gas. Therefore, ice or snow or the like coming into contact with the protective strips 54 melts and does not prevent flow of air through the passages formed by the fins 52.
Thus, the heat exchanger structure of FIGURES 5 and 6 includes means for protecting the cooling fins 52 against damage. Furthermore, moisture does not accumulate among the protective strips to freeze and to clog the passages formed by the fins.
Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof, and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as dis-closed and defined by the appended claims.
