3 Claims.
The present invention relates to cabinet convector heaters wherein the core is positioned horizontally in the cabinet.
My invention is especially adapted for use with hot water as the heating medium or cold water as the cooling medium.
An object of my invention is to provide a core of a simple design which will insure efficient operation with minimum attention.
Another object of my invention is to provide simpl means for trapping the vapor or air so they can be either automatically or manually discharged from the core without loosing any of, the heating or cooling medium.
A further object of the present invention is to provide end fastenings for the core to the side walls of the cabinet which do not require special screws or bolts and which are provided with means for optionally positioning the height of the individual core ends.
Generally stated, an object of my invention is to provide a core which is simple, light, easily manufactured at low cost and easily installed in the cabinet.
To these and other useful ends, my invention consists of parts, combinations or parts, or their equivalents, and mode of operation, as hereinafter set forth and claimed and shown in the accompanying drawing in which:
Fig. 1 is a perspective view of the preferred form of my improved heat transfer core comm plete and ready to be installed in a cabinet.
Fig. 2 is a side elevational fractional view of my improved core as illustrated in Figure 1,
showing a fraction of a cabinet and the fastenings of the core to the side walls of the cabinet.
Fig. 3 illustrates a modification of the core part of the fastening.
Fig. 4 is a fractional section of Figure 3, taken on line 5-4 of this figure.
As thus illustrated, my improved heat exchanger comprises a number of transversely spaced tubes l0 and a multiplicity of closely spaced fins H through which the tubes extend. I provide a header I! at one end of the core which is preferably'circular in cross section, as illustrated, and into which tubes ill extend and are bonded as is the custom in headers 0f the kind.
Header i2 is provided with an inlet or outlet connection I 3 which may be curved inwardly and having a suitable fitting for connection to the lead line as at it. Header i2 i provided with widely spaced plates l5, each being preferably bonded or brazed to the header as at it or these plates may be secured directly to some other part 7 of the core, preferably to the ends of members 2 I or as extensions to these members (see Figures 3 and 4). The outer edges of the plates I 5 are turned inwardly as at II for a short distance and then being turned outwardly as at l8, forming narrow vertical flanges l9 having spaced preferably angular elongated recesses 23 for a purpose which will hereinafter appear.
Fins H are provided with protecting shields 2| preferably similar to that shown in my Design Patent 128,514, July 29, 1941. I provide an elevated header 25 for the other end of the core similar to header I2. Tubes I II are preferably bent as illustrated in Figure 2 and extend upwardly as at 24 into header 25 and being bonded thereto similar to the other ends of the tubes.
In the figures, I illustrate the inlet and outlet tubes as being turned inwardly. The shape is optional. They may extend downwardly or at whatever positidn is most convenient for making connections to the lead lines.
In Figures 3 and 4 I illustrate a modification wherein the ends of members 2| are extended as at 33, each end being provided with upwardly extending spaced recesses 23 and downwardly extending spaced recesses 24 similar to recesses 20 in the other figures.
In this design, I provide open end headers 36 which are the exact length of the space between extensions 33 and I weld members 33 to the ends of members 36 as at 34 so as to make a strong and compact assembly. Clearly extensions 33 will answer as the closing means for the header ends.
In Figure 2 I illustrate a fraction of a cabinet having a rear wall 21 and side walls 28-28, the front wall being removed for convenience of iilustration. It will be noted that the cabinet is rectangular in cross section having front rear panels and side panels,
In cabinets of the class, means are provided for the inlet of air at the bottom and an outlet of the heated air at the top. The circulation of air is brought about either by natural draft or by means of a fan or fans (not shown).
In heat exchange cores of the class, air is always present in the heating or cooling medium when an up-feed, as illustrated, is used and it and is necessary, in order to secure the most eflicient operation, to provide means for trapping and releasing this accumulation. Whether header 25 is used for an outlet or an inlet header, it is preferably placed above the horizontal plane of tubes Hi so in the passage of the heating or cooling medium, the air or trapped fluid may accumulate in the top of the header.
For the purpose of draining the trapped air from header 25 either automatically or manually, I preferably provide a pipe 29 which extends upwardly and preferably outwardly through panel 28 and having at its end any standard means (not shown) for draining the air from the header either automatically or manually, the means being too well known to require illustration or description. Pipe 29 may be dispensed with and this draining means secured directly to header 25.
It will be seen that I have provided a heat transfer core having efficient and adequate means for trapping the fluid or air, the means having a large capacity so that if a manually controlled valve is provided, it need not be given attention oftener than once a week.
I provide means for mounting the core in the cabinet as follows:
U-shaped brackets 30-" are provided having inwardly and preferably upwardly extending flanges 3| of a thickness and position suit able for fitting into recesses 20 as clearly illustrated in Figure 2. Both brackets 30 may be permanently secured to the panel as the core can be moved into the cabinet drawer-like. That is, if there is an opening in the front of the cabinet for the purpose, otherwise one of the brackets may be removably secured to the panels by means of bolts as at 32.
It will be seen that the height of the core may be changed considerable and that the end of the core having header 25 may be positioned higher than header I! so as to facilitate trapping the fluid in header 25, or for that matter, the headers at both ends of the core may be connected to tubes l similar to header i2 and when the core is positioned in the cabinet, the header having the air vent, may be positioned one or more notches above the other header so as to assist in trapping the air or fluid.
When headers 36 are provided at both ends of the core as in Figures 3 and 4, then the outlet end of the core may be positioned a considerable distance above the inlet end in order to facilitate trapping the fluid in the outlet header. When a down-feed system is used in the design shown in Figure 2, there is no necessity for trapping fluid in either of the headers. For a down-feed, this core may be turned upside down by simply providing two sets of angled recesses as shown in Figure 3 and either end of the core may be placed higher than the other end.
Having thus shown and described my inven tion, I claim:
1. A device of the class described, comprising spaced circular in cross section substantially horizontally positioned headers, spaced tubes hav ing a multiplicity of closely spaced fins through which the tubes extend forming operating connections between said headers, said headers having widely spaced plates secured thereto, said plates having closely spaced recesses in the outer edges thereof, a cabinet, brackets secured to the end walls of the cabinet having intumed flanges adapted to extend into said recesses to thereby form supports for said core and provide means whereby the core ends may be optionally positioned.
2. A convector heater of the class described, comprising a cabinet, a heat exchange core adapted to be positioned transversely in said cabinet, spaced plates secured to the sides of said core, the ends extending past the ends of the core and having vertically spaced narrow relatively deep recesses therein, brackets secured to the side walls of said cabinet having inwardly projecting flanges adapted to optionally extend into said recesses and act to position and support the core.
3. A convector heater of the class described. comprising a cabinet, substantially horizontally positioned spaced open end header tubes having finned tubes forming an operating connection therebetween, plates secured to the front and rear ends of said fins and extending slightly past the outer edges of said headers and in contact with the ends thereof, vertically spaced narrow relatively deep recesses in the ends of said plates, brackets secured to the side walls of said cabinet having inwardly projecting flanges adapted to optionally extend into certain recesses and act as positioners and supports for the core, said header tube ends being welded to said plates to thereby form closures therefor.
