  • the present invention generally relates to a heat exchanger, more particularly to, a heat exchanger having at least one manifold is a tube type manifold.
  • heat exchanger includes heat exchange elements extended between a pair of manifolds.
  • the pair of manifolds may include a header and a cover adapted to encapsulate the header.
  • the heat exchange elements may be fluidically connected to the header provided in the pair of manifolds.
  • the header is connected with the cover, to form a fluidal connection between the heat exchange elements and an external fluid circuit.
  • the cover has to be connected to conduits of the external circuit carrying the fluid.
  • a connecting member preferably a connector or a connecting block is connected to the cover of the manifold.
  • the connector is brazed to the manifold to enable rigid connection between the connector and the manifold. Thereafter, the conduits are connected to the connector, thereby enabling fluid connection to the heat exchange elements.
  • some elements or parameters may be indexed, such as a first element and a second element.
  • 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.
  • an embodiment of the invention herein provides a heat exchanger.
  • the heat exchanger includes a pair of spaced apart manifolds, and a plurality of heat exchange elements extended between the pair of spaced apart manifolds.
  • at least one manifold of the pair of spaced apart manifolds includes a first part and a second part integrally formed with the first part at an angle. Further, the first part and the second part are having same profile and same cross-section.
  • the first part is connected to the second part at an angle ranging from 2° to 180°.
  • first part and the second part are perpendicular to each other.
  • the first part is connected with the second part along an axis of the first part

  • the manifold is a tube having the first part and the second part.
  • an open end of the second part of the manifold is connected to a connector that adapted to enable connection to the external fluid circuit.
  • the present invention relates to a heat exchanger having a pair of tube-type manifold.
  • Conventional heat exchanger may include a pair of manifolds, and heat exchange elements extended between the pair of manifolds. Further, a connector is connected to any one of the manifold to fluidically connect the heat exchange elements with an external fluid circuit.
  • a tube type manifold is provided in the heat exchanger.
  • the proposed heat exchanger may include a pair of manifolds. At least one manifold amongst the pair of manifolds includes two parts integrally formed together. In other words, these two parts are made from one element, i.e. they are distinguishable within a single component.
  • one part of the manifold is connected to heat exchange elements, and other part is connected to conduits of external fluid circuit, thereby eliminating a need for a connector to enable fluid communication to the heat exchange elements.
  • Figs. 1 and 2 illustrate perspective views of a heat exchanger 100, in accordance with an embodiment of the present invention.
  • the heat exchanger 100 includes a pair of manifolds 102A, 102B and a plurality of heat exchange elements 104.

  • one end of the first part 202 is fluidically coupled to the second part 204, and other end of the first part 202 is sealed with a sealing cap 304.
  • the sealing cap 304 may seal the cross-section of the first part 202, so that the fluid entering into the first part 202 of the manifold 102A may flow into the heat exchange elements 104.
  • the second part 204 of the manifold 102A may include a connector 306 provided at an end of the second part 204 to couple with the external conduits of the external fluid circuit.
  • the connector 306 is provided with the second part 204 to couple with the external conduits having different cross-section from the second part 204.

  • one end of the second part 204 of the manifold 102A is bent at an angle and other end of the second part 204 of the manifold 102A is coupled to the external conduits.
  • the bent end of the second part 204 is fluidically connected to the first part 202 of the manifold 102A.
  • the sealing cap 304 is connected to the end of the first part 202, so that cross-section of the manifold 102A is sealed at one end, and another end of the manifold 102A is connected to the external conduits of the external fluid circuit.
  • the heat exchanger 100 can be connected to the external conduits routed at any angle.
  • the heat exchanger 100 can be positioned in a spaced constrained environment, since external parts are not connected to the heat exchanger 100. As the manifold 102A does not require any external connector to connect the heat exchanger 100 with the external fluid circuit, weight, size and cost of the heat exchanger 100 are reduced.
