Abstract: The purpose of the present invention is to provide a tube assembly for a tubular heat exchanger and a tubular heat exchanger comprising the same, the tube assembly for a tubular heat exchanger being capable of enhancing efficiency in heat exchange between a heat medium and a combustion gas and also preventing high-temperature oxidation and the burn-out of a turbulator caused by the combustion heat of the combustion gas and preventing the deformation or damage of a tube which may occur in an environment with a high water pressure, thereby improving the durability thereof. The tube assembly for a tubular heat exchanger of the present invention, for achieving the purpose, comprises: a tube which is formed in a flat shape and enables a combustion gas generated in a combustion chamber to flow along the inside thereof and exchange heat with a heat medium which flows outside thereof; and a turbulator which is coupled to the inside of the tube and induces the generation of turbulence in the flow of the combustion gas.

Abstract: A vapor cycle heat exchanger has a plurality of heat exchanger lines and a distributor. The distributor comprises a distributor housing, a swirl vane, an atomizing nozzle, a plurality of nozzles, and a fluid line intersection. The distributor housing defines a main distributor line configured to receive a non-homogenous flow of the two-phase refrigerant fluid. The swirl vane is disposed within the main distributor line and configured to distribute the non-homogeneous flow into a symmetric fluid distribution. The atomizing nozzle is disposed downstream of the swirl vane. The routing lines each lead to one of the plurality of heat exchanger lines. The main distributor line branches into the routing lines at the fluid line intersection, which is situated downstream of the nozzle.
