Claim 6

The support of claim 1, wherein the projection of each element includes two arms diverging from an apex of the projection, each arm being connected to a leg section of the element.

Claim 7

The support of claim 1, wherein the means for securing the elements together includes spot welds located between end portions of the leg sections of adjacent elements.

Claim 8

The support of claim 1, wherein each channel is adapted to receive at least one heat exchanger tube and the projection and leg sections of each element are adapted to separate heat exchanger tubes in adjacent channels.

Claim 9

A heat exchanger tube support for supporting a plurality of heat exchanger tubes within a conduit of a heat exchanger, comprising: three metal elements having identical configurations, each of said elements defining a generally concave side and a generally convex side and including a radially extending projection defined in a central area of the element, the projection including two arms diverging from an apex of the projection and extending into an area partially encompassed by the concave side, a leg section extending from each diverging arm, the leg section including an intermediate portion and an end portion, the intermediate portion extending from a diverging arm to the end portion, the end portion extending at an angle from the intermediate portion to an inside wall of the conduit, a channel defined between each diverging arm of the projection and each intermediate portion of each leg section, each channel being adaped to receive a heat exchanger tube with adjacent heat exchanger tubes being separated by at least one of the projections and leg sections; means for securing an end portion of each element to an end portion of an adjacent element with each end portion extending radially outward, with each channel opening radially outward, and with the three elements enclosing an interior area within the heat exchanger tube support, the interior area being adapted to receive a heat exchanger tube; and means for securing the heat exchanger tubes within the channels.

Claim 10

A heat exchanger tube support for supporting a plurality of heat exchanger tubes within a conduit of a heat exchanger, comprising: three metal elements having identical configurations, each of said elements defining a generally concave side and a generally convex side and including a radially extending projection defined in a central area of the element, the projection including two arms diverging from an apex of the projection and extending into an area partially encompassed by the concave side, a leg section extending from each diverging arm, the leg section including an intermediate portion and an end portion, the intermediate portion extending from a diverging arm to the end portion, the end portion extending at an angle from the intermediate portion to an inside wall of the conduit, a channel defined between each diverging arm of the projection and each intermediate portion of each leg section, each channel being adaped to receive a heat exchanger tube with adjacent heat exchanger tubes being separated by at least one of the projections and leg sections; means for securing an end portion of each element to an end portion of an adjacent element with each end portion extending radially outward, with each channel opening radially outward, and with the three elements enclosing an interior area within the heat exchanger tube support, the interior area being adapted to receive a heat exchanger tube; and means for securing the heat exchanger tubes within the channels.

Claim 11

A heat exchager having a heat exchanger tube support, comprising: a conduit, a plurality of heat exchanger tubes arranged within the conduit; a heat exchanger tube support which supports said plurality of tubes within the conduit, each of said tubes being spaced from one another and from an inside wall of the conduit, the heat exchanger tube support including three identical elements, each element being a strip of material defining a projection at a mid-section of the element, two leg sections extending from the projection and a channel being defined between each leg section and the projection, the three elements being connected together at the leg sections of adjacent elements, with each element being connected to an adjacent element, each channel receiving at least one heat exchanger tube and the projection and leg sections of each element separating the heat exchanger tubes in adjacent channels.

Claim 12

A heat exchager having a heat exchanger tube support, comprising: a conduit, a plurality of heat exchanger tubes arranged within the conduit; a heat exchanger tube support which supports said plurality of tubes within the conduit, each of said tubes being spaced from one another and from an inside wall of the conduit, the heat exchanger tube support including three identical elements, each element being a strip of material defining a projection at a mid-section of the element, two leg sections extending from the projection and a channel being defined between each leg section and the projection, the three elements being connected together at the leg sections of adjacent elements, with each element being connected to an adjacent element, each channel receiving at least one heat exchanger tube and the projection and leg sections of each element separating the heat exchanger tubes in adjacent channels.

Claim 13

The heat exchanger of claim 9, further comprising means for securing the heat exchanger tubes within the channels.

Claim 14

The heat exchanger of claim 10, wherein the means for securing the heat exchanger tubes includes a band which surrounds the tubes.

Claim 15

The heat exchanger of claim 10, further comprising means for spacing the heat exchanger tubes from an inside wall of the conduit.

Claim 16

The heat exchanger of claim 12, wherein the leg sections of adjacent elements extend radially to the inside wall of the conduit, each leg section having a length sufficient to space the tubes from the inside wall of the conduit.

Claim 17

The heat exchanger of claim 9, wherein at least one heat exchanger tube is arranged centrally within the three elements.
