6 Claims. (Cl. 257-133) This invention relates to radiators for space heating and more specifically to a novel and improved heat radiator for heating homes, oiiices and the like that is particularly useful as a so-called base-board radiator.
Many types of radiators for Yspace heating have been proposed and known structures have not been found entirely satisfactory for a number of reasons, among them being the relatively high cost of manufacture and installation. While base-board radiators are generally fabricated in sections, each section is generally formed of a number of individual components for assembly when the equipment is installed. This greatly complicates installation procedures and adds materially to the cost of the heating plant. Other disadvantages of prior known radiators of the base-board type include the relatively inefficient utilization of space to obtain maximum transfer of heat to the ambient air, `the relatively complicated mounting procedure and the requirement of special tools and equipment for assembly and joinder of the sections.
The above and other disadvantages of prior radiators are overcome with this invention which is characterized by its simplicity, ease of installation, and improved etliciency and appearance.
Another object of this invention is to provide a basic heat exchanger section of utility especially in and for sectional base-board radiators and incorporating on one attractive die cast part a channel for a heat carrying fluid, a channel for directing air being heated across the heated surface, sturdy and damage-resistant heat conducting tins, and a mounting therefor which will enable substantially unrestricted expansion and contraction of the section or sections due to temperature changes.
Another object of the invention resides in the provision of a sectional base-board radiator employing such basic sections that affords etiicient utilization of space for maximum transfer of heat to the air and whose sections are provided with improved telescopic connectors which greatly facilitate coupling the sections one' to the other so that they may be joined together using a drive't joint with suitable adhesive sealant'and desired lengths achieved without cutting, iitting,v threading, welding or soldering.
Still another object of the invention is the provision of au improved sectional base-board radiator wherein each section constitutes a complete, substantially unitary structure that can be readily attached to adjoining sections and to a supporting wall and is soV constructed and arranged as todirect heat away from the wall to prevent wall streaking.
A further object of the invention resides in the provision of novel input and output terminal sections for such improved basic heat exchanger sections, which are die cast and permit easy and quick connection to such sections and which make possible easy and quick con nections to fluid conducting tubes or pipes either from below through the oor or from the back through the wall, whichever is more convenient, with minimum labor and structural changes.
A still further object of the invention resides in the provision of a simple and inexpensive valve as a part of one terminal.
The above and other objects and advantages of the invention will become more evident from the following description and accompanying drawings forming part of this application.

Figure 15 is a cross sectional view taken along the line 15-15 of Figure 13; and
Figure 16 is a cross sectional view of Figure 14, taken along the line 3.6-16 thereof.
Referring to Figure l, the base-board radiator in accordance with the invention is denoted by lthe numeral 20 and includes a heat exchanger having a plurality of similar heat exchanger sections 24a to 24d, an input terminal 26 for connecting the heat exchanger to a fluid inlet pipe 32, and an output terminal 28 for connecting the heat exchanger to a Huid return 34. 'l'lhe heat exchanger sections 246.' through 24d are coupled to each other by telescopic coupling means 30h, 30e and 30d. Similar coupling means 30a and 30e connect the heat exchanger sections to the input terminal 26 and to the output terminal 28. Since the heat exchanger sections 24a through 2li-d and the coupling means 30a .through 30e are substantially identical, it is possible to assemble a base-board radiator using any desired number of sections in series with the ends being terminated by the terminal members 26 and 28.
More specifically and with reference to Figures 2 through ll, each heat exchanger section 24a through 24d includes a conduit di?, a plurality of ns 42, a deector 44 and a mounting hole 46. Each section is pref; erably fabricated by die casting with the conduit 40 and the fins d2 formed integrally one with the other. The conduit 4t) for the heated fluid is tapered in plan as w-ill be observed from Fig. 4. it has its smallest section in the center and gradually increases in size toward both ends, thus permitting the core used in the die casting to be withdrawn. Notwithstanding this gradually increasing across-section, the front and rear walls of theV heat exchangerrsection are maintained at a substantially j ..1 'Y v y assegna form thickness over substantially the length of the'co'nduit, thus ensuring the preservation of maximum strength and most eicient utilization of the die casting material. it be-.Qbser-Yed ,from .Fig- 14 that the .heat radiating ii'ns'42` though co-planarL insofar as their tipsraregcon? cerne'dare 0f greatest 1f r1gtlf1` at the. tenter, Qf the Section in conformitr with the presen/ati@ ofthe urliformiwall thicknesspver thelength of the section.- `rl`he ns 42es;

The input terminal'section is preferably die-cast inthe same manner asj'the radiator sections. By reason of the `improved arrangement of valve elements in terminal 26, twoy or Ymore inlet openings 52 and 54 may be provided to facilitatejconnection of the radiator to the heating system.

The femalel connector part 38 isgin the form of a tapered opening 38 for telescopically receiving the male Aconnector part 36 of an` adjoining section in a drive -iit joint to form a water-'tight seal with ai continuous, uninterrupted passage through" both' sections.

In, either case theunused inlet would Vbe plugged as by'means of-,a suitable threaded plug(not shown), theinletrbeing usuitably threaded, as shown, to receive the plug.

The outlet terminal section 28 for returning heat'carrying uid from thje'terminal heat exchanger section to the uid return pip/e4 34includes a tapered opening 38a for acceptinga Vtapered male connecting member such as the'c'onnector part 36 offa radiator section124, an entry'port 70 for receiving fluid from the enclosed channel 40 ofthe 'adjoining radiator section, exit port 72 and 74 forV connecting the terminal to an'outlet pipe such as pipe 34 of FigureY 1 and ach'amber 76 Yinterconnecting the entry port 70 to the exit ports. Figures 6 and 8 illustrate the outlet terminal 28and show the right angular relationship between the exit ports.'V i
t A modified base-board radiator 20 is shown in Figure 12 andrincludes improved locking means 80 for holding radiator may, thus be" obtained by coupling the basic heat the sections24 and terminals'26 and 28 in position .one relative Vtothe other. VAs embodied inthe basic radiator sections, the locking means consists of a slot in one end of the basic section and a'lip on Vthe other end. When tw adjacent sections aretelescoped together. the lip can be `spru'ngor driven into the slot toV prevent the sections from being pulled apart. This willY relieve the adhesive sealant of any strainin tension. 'Figure to 16 show details of this/improved feature.

The elements of these 'figures corresponding to' elements of Figures 13 and 15 have been designated byY like primed'numerals. `It will be understood that the locking means rSilb, c` and d for connecting the successive radiator' 'sections one to the Aother are similarly yconstructed; 'j fif j `v With the` locking means as described above, the radiatorsectio'nsare firmly and postivelysecured oneto the otherand ,will not separate even when sulaje'zfzgtedf,to continud vibration Vof 4sudden' changesin ten'lperature -and the adhesive sealant is relieved of any strain in tension.
While only certain embodiments of the invention have been described, it is apparent that modications, alterations and changes may be made without departing from the true scope and spirit of the present invention as dened by the appended claims.
