摘要:
An element (1) of a heating radiator has a body (2), provided with an internal chamber (4) for water circulation and has a substantially tubular end part (10), which extends along an axis (A) and is closed by a plug (20); the end part (10) has a radially outer collar (18) around the opening (12) and a pair of flat and parallel opposite faces (19), substantially orthogonal to the axis (A) and at least partially overlapping in axial projection; the plug (20) is mechanically fastened to the collar via a pair of parallel, flat, opposite fixing surfaces (29), which face one another and are orthogonal to the axis (A) and are directly in contact and axially gripped and squeezed against respective faces (19) of the collar (18).

To prevent the heat exchange efficiency of a heat exchanger from being lowered by interstices between collection header pipes and fins adjacent to the collection header pipes. Seal members (51, 52, 53, 54) are adhered to a blower chamber-side front panel (25), an air blocking plate (60), a machine chamber-side side panel (24), and a partition panel (28). The seal members (51, 52, 53, 54) are pressed by the blower chamber-side front panel (25), the air blocking plate (60), the machine chamber-side side panel (24), and the partition panel (28) against collection header pipes (34, 35) and heat transfer fins (32) in the environs of interstices (IS1, IS2) facing the blower chamber-side front panel (25), the air blocking plate (60), the machine chamber-side side panel (24), and the partition panel (28), become deformed, and close the interstices (IS1, IS2).
摘要:
A heat exchanger with improved heat exchange performance is provided. An indoor heat exchanger (6) is a heat exchanger that allows supercritical CO2 refrigerant to radiate heat to the air, and includes a plurality of plate fins (11) and a plurality of heat transfer tubes (12). Four or more rows (61 to 72) of heat transfer tubes (12) arranged in the direction crossing the airflow are formed in the upstream-to-downstream direction of the airflow. Each plate fin (11) is divided between at least one pair of adjacent rows (61, 62). The refrigerant flows from the heat transfer tubes (12) in the row (72) on the downstream side of the airflow to the heat transfer tubes (12) in the row (61) on the upstream side of the airflow.
摘要:
This invention relates to a heating radiator (1, 10, 100) comprising at least two radiant elements (2, 20, 200) provided with a passage for a heat transfer fluid, in which the two elements (2, 20, 200) have a tubular structure and are installed in series with respect to the delivery of the heat transfer fluid, in which each element (2, 20, 200) is divided at least in a first (6, 60, 600) and a second communicating chamber (6A, 60A, 600A).
摘要:
The invention provides a modular element for composing heating radiators comprising a die-casting finned structure of aluminium, defining one, two or more vertical conduits extending between two horizontal conduits, namely an upper and a lower, in which in the or each vertical conduit a tubular insert is disposed, of a metal with a higher mechanical strength and chemical corrosion resistance than the material forming the finned structure. The inner surface of the upper and lower horizontal conduits in said structure is lined with a layer of anticorrosive material deposited thereon after casting the structure. The invention also relates to a process for manufacturing the modular radiator element.
