Abstract
Elements and tube-type heat exchanger employing such elements include a hollow core and a spiral baffle formed integrally with the core and extending axially thereof. The spiral baffle includes openings for receiving pipe bundles extending axially of the core. The core of each of the elements is stepped and recessed such that a plurality of the elements may be fitted together to form the heat exchanger.
Claims14
An element for use in a tube-type heat exchanger comprising:
- hollow core means;
- spiral baffle means formed integrally with said core means and extending axially thereof, said spiral baffle means being formed on said core means in the form of a spiral which comprises at least part of a coil in said element;
- and
- at least one opening in said spiral baffle means for receiving a pipe extending axially of said core means,
- at least one of said core means and baffle means of said element including aligning means adjacent one end thereof for cooperating with complementary aligning means on another element to align said elements and the pipe receiving openings of the elements with each other, said aligning means comprising the ends of said spiral baffle means in each said element being located in a plane radial to the axis of said core means and one said end projects over the end of said core means.
2 more elements
An element for use in a tube-type heat exchanger comprising:
- hollow core means comprising a substantially hollow cylinder the internal diameter of which, at one end, is widened in steps by an inner annular recess in the cylinder, and the external diameter of said cylinder, at the other end thereof, is reduced in steps complementary to said first mentioned steps, by an outer annular recess in said cylinder;
- spiral baffle means formed integrally with said core means and extending axially thereof;
- and
- at least one opening in said spiral baffle means for receiving a pipe extending of said core means;
- at least one of said core means and baffle means of said element including aligning means adjacent one end thereof for cooperating with complementary aligning means on another element to align said elements and the pipe receiving openings of the elements with each other, said aligning means comprising the ends of said spiral baffle means in said element being located in a plane radial to the axis of said core means and one said end projects over the end of said core means.
2 more elements
An element for use in a tube-type heat exchanger comprising:
- hollow core means;
- at least one axially extending molded rib on the outer surface of the core means of said element, said rib passing through said spiral baffle means in portions thereof spaced from said pipe bundle;
- spiral baffle means formed integrally with said core means and extending axially thereof;
- and
- at least one opening in said spiral baffle means for receiving a pipe extending axially of said core means;
- at least one of said core means and baffle means of said element including aligning means adjacent one end thereof for cooperating with complementary aligning means on another element to align said elements and the pipe receiving openings of the elements with each other.
