Abstract
In a header tank construction which includes a sheet metal tank 10 connected to a tube plate 14, and wherein sealing means such as a gasket 16 is located between the tank and the tube plate, the edge portion 11 of the tank is turned over so that the free edge of the turned- over portion is spaced from the wall of the tank to define therewith a slot 12, and a connection to secure the tank to the plate is formed either, as in Fig. 1, by a separate clip 18 which engages at one end thereof in the slot and at the other end thereof under the tube plate or, as in Fig. 2, by an integral portion 20 of the tube plate a hook- shaped portion of which is engaged in the slot by crimping. <IMAGE>
Description
SPECIFICATION
Header Tank Construction
This invention relates to a header tank construction and particularly, but not exclusively, to header tanks for use with heat exchangers. The invention is more particularly concerned with the connection between a header tank and a tube plate.
Header tanks have hitherto been made of plastics material and have been formed with an outwardly-directed flange. A tube plate has been connected to the tank by shaping the edge of the plate to fit around and engage the flange, a gasket being located between the flange and the plate for sealing purposes.
Sheet metal header tanks have also been made and these have either been formed with an outwardly-directed flange attached to the tube plate by bolts or the edge of the tank is located and soldered in a U-shape channel at the edge of the tube plate.
The invention is concerned with a header tank construction especially for tanks made from sheet metal whereby a joint between the tank and the tube plate can be simply and effectively made.
According to the invention a header tank construction comprises a sheet metal tank having a turned-over edge portion, the free end of said portion being spaced from the wall of the tank to define a slot, a tube plate, connected means integral with or engaging with the tube plate and engaging in the slot whereby the tank is connected to the plate, and sealing means located between the tank and the tube plate.
In the case where the connecting means is in engagement with the tube plate such means meay comprise resilient clips which fit under the tube plate, around the outer edge of the tube plate and into said slot. With this arrangement the tube plate may be flat except for the outer edge which is formed as an upwardly turned wall transverse to the plane of the plate.
In the case where the connecting means is integral with the tube plate the outer edge of the tube plate may be bent to extend around the turned-over edge of the tank and into said slot.
In both cases the connecting means forms a positive connection between the tube plate and tank due to the engagement of said means in the slot, without the need for bolts, solder or like means.
The sealing means may in each case be located under the turned-over edge of the tank against the upper surface of the tube plate.
Further features of the invention will appear from the following description of various embodiments of the invention given by way of example only and with reference to the accompanying drawings in which:
Fig. 1 is a sectioned scrap view of one embodiment employing clips,
Fig. 2 is a sectioned scrap view of another
embodiment,
Fig. 3 is a section showing an embodiment similar to that of Fig. 2, and
Fig. 4 is a section showing a further embodiment similar to that of Fig. 2.
Referring to the drawings in which the same reference numerals are used for similar parts in the various figures and firstly to Fig. 1, a header tank 10 for a radiator (not shown) is formed of sheet metal and has a lower edge formed with an integral turned-over portion 11 of generally Ushape to define a slot 12 between the free end of the portion and the outside surface of the wall 13 of the tank, that is between the limbs of the U.
A tube plate 14 is generally flat and located at a right angle to the wall 13, and the outer edge of the plate 14 has a bent-over edge portion 1 5 extending generally parallel to the wall 13 and located to the outer side of the portion 11 of the tank. A gasket 1 6 is located under the portion 11 and between the tank and the tube plate 14 to effect a seal between these parts.
The tank 10 is secured to the tube plate by one or more resilient clips 1 8 which engage under the plate 14 and into the slot 12. The clip 18, made for example of spring steel, is formed with a bowed central portion 1 8a located between a turned-over limb 1 8b and a right angle limb 1 sic, and the central part of the portion 1 8a engages the edge portion 1 5 of the plate, the limb 1 8b engages in the slot 12 and the limb 1 sic engages the underside of the plate 14.
The tank 10 and the plate 14 are assembled by locating the gasket 1 6 in position, bringing the tank and plate together and then clipping the clip 18 over the edge portions to the position described and shown.
It will be appreciated that the clip may be released from the assembled tank if it is desired to separate the tube plate from the tank. Clips 1 8 may be at spaced locations along the sides of the tank or there may be a continuous clip along each side of the tank.
Referring now to Fig. 2, a header tank 10 is formed with a turned-over portion 11 as for the previous embodiment. A tube plate 14 is generally flat and is formed at its outside edge with a hook-shaped integral connecting portion 20 having a limb 20a extending at a right angle to the plate 14 and a hook 20b contiguous with the limb 20a and engageable in a slot 12 defined by the portion 11.
A gasket 1 6 is located between the portion 11 and the tube plate 14 to effect a seal between these parts.
In assembling the embodiment of Fig. 2 the portion 20 is located over the turned-over portion 11 by crimping.
The Fig. 3 embodiment is similar to that of Fig.
2 except that the turned-over portion 11 of Fig. 2 is modified to provide a tapered slot 12 with the wider end facing outwardly. Such a turned-over portion may also be employed in the Fig. 1 embodiment.
Referring to Fig. 4 this embodiment is similar to that of Fig. 2 except that to accommodate the lower edge of the tank 10, the plate 14 is formed with a recess 22 of generally U-shape, a gasket 1 6 being located in the base of the U and the lower edge of the tank engaging with the gasket to effect a seal.
It will be appreciated that the recess 22 of Fig.
4 can be provided in the arrangement of Fig. 1 or
Fig. 3.
In each of the arrangements of Figs. 2, 3 and 4 the portion 20 may have the limb 20a and hook 20b of castellated form.
Each of the described embodiments allows the use of dissimilar metals for the tank and tube plate without the need for bolted joints and the joint may in certain cases be demountable. The
described embodiments have particular application where relatively large tanks are
required and the use of plastics tanks is uneconomic. The gasket 16 may be of rubber of
suitable cross-section.
