A heat exchanger includes: a hollow pillar shaped honeycomb structure, a first cylindrical member, a second cylindrical member, a cylindrical guide member, and an upstream cylindrical member. A communication port is provided between the downstream end portion of the guide member and the second cylindrical member or at the guide member. The second cylindrical member has a horn shape in which a diameter of the upstream end portion of the second cylindrical member is increased radially outward. The upstream cylindrical member has a flange portion, and a rising position of the flange portion is located on a more downstream side than the upstream end portion of the first cylindrical member.

A heat exchanger module comprises several U-tubes for a first fluid flow, the U-tubes having two straight sections connected by a U-shaped portion. Inlet ends of the several U-tubes are connected with an inlet collector tube and outlet ends of the several U-tubes are connected with an outlet collector tube. The two straight sections of the U-tubes have a different length such that a longitudinal axis of the inlet collector tube and a longitudinal axis of the outlet collector tube are arranged at different heights with respect to a height of the heat exchanger module. Also provided is a method for manufacturing the heat exchanger modules and a tubular heat exchanger comprising a plurality of heat exchanger modules.

A heat exchanger includes front and rear walls forming a flue gas space such that a fluid flowing through a channel formed in the front and rear walls can exchange heat with flue gas in the flue gas space, in use. An entirety of the back wall extends along a first plane, and the back wall is provided with a back fin. The front wall includes a lower portion extending upwardly along the back wall, and an upper portion extending upwardly from an upper end of the lower portion and outwardly away from the back wall to form a combustion space of a flammable gas between the upper portion and the back wall. The upper portion is provided with a front fin. The front and back fins are arranged symmetrically with respect to a virtual line along which the flammable gas is to be injected into the combustion space.

A heat exchanger unit according to the present invention includes a sensible heat exchanger including a sensible heat exchange pipe disposed in a sensible heat exchange area for heating water used for heating by receiving sensible heat generated by a combustion reaction, wherein the sensible heat exchange pipe receives the water used for heating and flows same through the interior, and a sensible heat fin disposed in the sensible heat exchange area. The sensible heat fin is formed in a plate shape across the sensible heat exchange pipe and penetrated by the sensible heat exchange pipe; and a latent heat exchanger positioned downstream from the sensible heat exchange area on the basis of a reference direction, which is a flow direction of combustion gas generated during the combustion reaction, the latent heat exchanger including a latent heat exchange pipe disposed in a latent heat exchange area.
