Description
- The present invention generally relates to a heat exchanger, more particularly, to a header-tank assembly of a heat exchanger provided with a groove-protrusion setup to retain the tank within the header while assembling the tank with the header of the heat exchanger.
- Generally, heat exchanger are provided with a pair of tanks to enable introduction or reception of fluid to or from the heat exchanger. The heat exchanger may include a core provided with a pair of headers at both side of the core. The pair of headers is adapted to be coupled with the pair of tanks, thereby enabling the fluid circulation to the core of the heat exchanger. Further, a gasket is introduced to provide proper sealing between the pair of tanks and the pair of headers. The pair of headers is brazed with the core and it is provided with any connecting means to couple it with the pair of tanks. The connecting means may be tabs formed on the periphery of the pair of headers and adapted to be crimped on the tanks to enable connection between the pair of tanks and the pair of headers. To connect the pair of tanks with the pair of headers, a series of steps are to be performed. Initially, the gasket is provided on the pair of headers, followed by placing the pair of tanks on the respective headers of the core. Upon placing the pair of tanks on the respective headers, the assembly is moved to a machine in which the tabs formed on the headers are crimped/bent on the foot portion of the respective tanks. In order to enable optimal crimping between the pair of tanks and respective headers, the pair of tanks have to lie flat on the gasket provided on the respective headers without any inclination of the tank. Such a header and tank assembly is known from
US 2002/144808 A1 . - In case the pair of tanks has its centre of gravity distant from a symmetric plane of the pair of tanks, the pair of tanks may pop from the respective header while assembling the tank on the respective header. Further, the pair of tanks may not lie flat on the gasket provided on the respective header, which may lead to improper connection between the pair of tanks and respective headers. Further, any inclination of the tank with respect to the respective header prevents the tabs formed on the header from being crimped on the tanks, and it may lead to damaging the gasket e.g., by pinching. In case the pair of tanks having centre of gravity distant from symmetry plane of the tanks, the pair of tanks may experience topping out of tank on one side from the respective header and results in falling out of the tank from the respective header.
- Accordingly, there remains a need for an assembly that retains the tanks in the respective header while assembling. Further, there remains another need for the assembly that avoid topping out of the tanks from one side of the respective header while crimping the tank onto the header.
- In the present description, some elements or parameters may be indexed, such as a first element and a second element. In this case, unless stated otherwise, this indexation is only meant to differentiate and name elements which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.

- In one embodiment, the protrusion is formed on the outer wall of the foot portion of the tank on a side opposite to the first side of the tank, and the groove is formed on inner wall of the header, complementary to the protrusion.
- In another embodiment, the protrusion is formed on the inner wall of the header, and the groove is formed on the outer wall of the foot portion of the tank on a side opposite to the first side of the tank.
- In one example, the protrusion is formed throughout any one of the outer wall of the foot portion of the tank, and the inner wall of the header.
- In another example, the groove is formed throughout any one of the outer wall of the foot portion of the tank, and the inner wall of the header.
- Further, the protrusion comprises a slope adapted to slide into the groove when the tank is positioned on the header.
- Further, a gasket disposed on a gasket recess formed on the header is adapted to provide sealing between the header and the tank when the tank is positioned on the header.

Theheat exchanger 100 includes aheat exchanger core 10 having a pair ofheaders 102 to receive heat exchange elements (not shown in figures). The pair ofheaders 102 may be brazed with theheat exchanger core 10 and fluidically connected to the heat exchange elements. Theheat exchanger 100 further includes a pair oftanks 104 adapted to be coupled with the pair ofheaders 102 provided with theheat exchanger core 10. The pair oftanks 104 enables fluid communication with theheat exchanger core 10. In one example, onetank 104 may provide the fluid to theheat exchanger core 10, and other may receive the fluid from theheat exchanger core 10. For the sake of brevity and clarity, one header and one tank are shown in the figures and accordingly explained in the description. Further, theheader 102 and thetank 104 are collectively referred to as a header-tank assembly 100A. Thetank 104 has afoot portion 106 adapted to be in-contact with theheader 102. Further,tabs 114 defined on theheader 102 are adapted to be crimpled on thefoot portion 106 of thetank 104 to enable a rigid connected between thetank 104 and theheader 102. - Further, the
tank 104 may include aconduit 112 to introduce or receive the fluid to or from theheat exchanger core 10. Further, theheader 102 is provided with a gasket (not shown inFigs. 1 and2 ) to enable fluid-tight connection between theheader 102 and thetank 104. In one embodiment, theheader 102 is provided with thetabs 114 formed on the periphery/edges of theheader 102. Thetabs 114 are adapted to bend on thefoot portion 106 of thetank 104, once thetank 104 is placed on theheader 102. In one embodiment, thetank 104 may have its centre of gravity outside of the symmetric plane of thetank 104 with respect to centre of theheader 102, since thetank 104 is asymmetrical in shape and have unbalanced mass in one side of thetank 104. In one example, the symmetric plane of thetank 104 is defined on a point on which both sides of thetank 104 have equal mass. In such cases, thetank 104 may pop-out from theheader 102 at one side, while crimping thetank 104 on theheader 102. In one embodiment, theconduit 112 is formed on afirst side 104A of thetank 104, so the centre of gravity is moved out of the symmetric plane of the tank, thereby thetank 104 may not lie flat on theheader 102 and there may be an inclination between thetank 104 and theheader 102. Such inclination may lead to toppling of thetank 104 while assembling thetank 104 on theheader 102 and to damaging of the gasket as pinching, provided in theheader 102. As theconduit 112 is connected from thefirst side 104A of thetank 104, the centre of gravity of tank is shifted towards thefirst side 104A of thetank 104. To overcome such issues, protrusions and grooves (not shown inFigs. 1 and2 ) are provided on theheader 102 and thetank 104 respectively. Further, placement of theprotrusions 108 and thegrooves 110 are explained in forthcoming figures. -

Thegasket 202 can be of rubber or any flexible material, which can withstand high temperature. Further,Figs. 4 and5 , illustrate perspective views of theheader 102 having thegrooves 110. Further, thegrooves 110 may be formed on aninner wall 204 of lateral sides of theheader 102 as shown inFigs. 4 and5 . In one example,Fig. 4 illustrates thegrooves 110 formed on theinner wall 204 of a firstlateral side 206A of theheader 102, andFig. 5 shows thegrooves 110 formed on theinner wall 204 of a secondlateral side 206B ofheader 102. Thegrooves 110 are adapted to receive corresponding protrusions formed on thetank 104, to retain thetank 104 on theheader 102 while crimping thetabs 114 on thefoot portion 106 of thetank 104. In a preferred embodiment, at least onegroove 110 is optimal to retain thetank 104 on theheader 104 while crimping thetabs 114 on thefoot portion 106 of thetank 104. In such case, thegroove 110 is formed on a side of theheader 102, which is opposite side of the first side of thetank 104. For example, if thetank 104 has theconduit 112 in thefirst side 104A of thetank 104, the centre of gravity is on thefirst side 104A of thetank 104. In such case, thegroove 110 can be formed on, an opposite side to thefirst side 104A of thetank 104, on theheader 102. Further, placement of thegroove 110 clearly explained in the forthcoming figures. - In one embodiment, the
grooves 110 can be formed throughout the inner circumference of theinner wall 204 of theheader 102. In another embodiment, thegrooves 110 can be formed at regular intervals on theinner wall 204 of the both the first and secondlateral sides header 102. In another embodiment, thegrooves 110 can be formed on theinner wall 204 of the either of the firstlateral side 206A or the secondlateral side 206B of theheader 102. Further, thetank 104 is adapted to be received between both the firstlateral side 206A and the secondlateral side 206B of theheader 102. In one example, an outer wall of thetank 104 is in contact with theinner wall 204 of theheader 102 when thetank 104 is placed on theheader 102. -
FIGS. 6 and7 illustrate perspective views of thetank 104 of theheat exchanger 100 ofFIG. 1 . Thetank 104 includes thefoot portion 106 provided on the periphery of thetank 104, and theouter wall 302 is adjacent to thefoot portion 106. Further, theprotrusions 108 are provided on theouter wall 302 of thetank 104. In one embodiment, theprotrusions 108 are provided on theouter wall 302 of lateral sides of thetank 104. In one embodiment, theprotrusions 108 may be formed on theouter wall 302 of a first lateral side oftank 304A or a second lateral side oftank 304B. In another embodiment, theprotrusions 108 may be formed on theouter wall 302 of both the first and second laterals sides oftank protrusions 108 are formed a lateral side which is opposite to the centre of gravity of thetank 104 or thefirst side 104A of thetank 104. In this example, theconduit 112 is formed in a direction same as the first lateral side oftank 304A, so the centre of gravity may be oriented towards the first lateral side oftank 304A. Hence, there is possibility of topping of thetank 104 from theheader 102 at the second lateral side oftank 304B, so theprotrusions 108 are formed on the second lateral side oftank 304B as shown inFig. 6 . Theprotrusions 108 formed on theouter wall 302 of the second lateral side oftank 304B are complementary to thegroove 110 formed in theinner wall 204 of the secondlateral side 206B of theheader 102. Thereby, connection between thetank 104 and theheader 102 is formed which retains thetank 104 on theheader 102 while assembling thetank 104 on theheader 102. As shown inFigs. 6 and7 , theprotrusions 108 are formed on theouter wall 302 of the second lateral side oftank 304B, and theouter wall 302 of the first lateral side oftank 304A is protrusion-free side. In one example, thetank 104 requires at least oneprotrusion 108 to connect or to retain thetank 104 on theheader 102. Further, theprotrusions 108 include a slope adapted to slide into thegrooves 110 formed on theheader 102, when thetank 104 is positioned on theheader 102. Theheat exchanger 100 can be a water cooled condenser. -
FIG. 8 illustrates an exploded view of thetank 104 on theheader 102 of theheat exchanger 100 ofFig. 1 . In the shown exploded view of thetank 104 and theheader 102, theprotrusions 108 are formed on thetank 104 and thegrooves 110 are formed on theheader 102. Theprotrusions 108 are complimentary to thegrooves 110 to receive theprotrusions 108 in thegrooves 110, when thetank 104 is placed on theheader 102 of theheat exchange core 10. Although theprotrusions 108 are formed on thetank 104 and thegrooves 110 are formed on theheader 102, it is possible to configure theprotrusions 108 on theheader 102 and thegrooves 110 on thetank 104. In such configuration, theprotrusions 108 are formed on theheader 102 and thegrooves 110 are formed on thetank 104. In this embodiment, theprotrusions 108 are formed on theinner wall 204 of the first and secondlateral sides header 102. Further, thegrooves 110 are formed on theouter wall 302 of thefoot portion 106 of thetank 104. Theprotrusions 108 slide into thegrooves 110, when thetank 104 is placed on theheader 102. Then, thetabs 114 are bend over thefoot portion 106 of thetank 104 to enable a rigid connection between thetank 104 and theheader 102. As theprotrusions 108 and thegrooves 110 enables thetank 104 to retain on theheader 102, there is no toppling of tank while assembling thetank 104 on theheader 102, even though thetank 104 has its centre of gravity outside the symmetric plane of thetank 104. Thereby, the assembling time of thetank 104 on theheader 102 also reduced.
