摘要:
Even with a plurality of heat exchange function surface units, a heat exchanger (1) can suppress an influence of the gravity exerted on refrigerant and suppress reduction of heat exchange performance in each of the surfaces. The heat exchanger (1) has the plurality of heat exchange function surface units (3), and includes an upper header pipe (5), a lower header pipe (7), and a plurality of heat exchange pipes (9) provided between the pair of upper and lower header pipes in each of the heat exchange function surface units. The plurality of heat exchange function surface units have a parallel connection relationship, and a plurality of the lower header pipes are connected to a lower collection pipe (19) through a branch current adjusting section (17).

A heater core includes a plurality of plate pairs. Each plate pair defines a respective fluid flow chamber. Each plate pair has a proximal plate defining a respective proximal plate plane and a distal plate defining a respective distal plate plane. Each of the proximal plate planes and the distal plate planes are parallel. Each plate pair has bilateral symmetry about a medial plane orthogonal to the proximal plate planes. A circular inlet aperture is defined in each respective proximal plate and each respective distal plate of the plurality of plate pairs. Each inlet aperture has a center on the medial plane. The inlet apertures are aligned on a common inlet aperture axis. A circular outlet aperture is defined in each respective proximal plate and each respective distal plate of the plurality of plate pairs. Each outlet aperture has a center on the medial plane.

A refrigerant distribution and supply section (89) includes: a refrigerant supply section (86) in which plural supply spaces (86A to 86L) are formed; a refrigerant introduction and distribution section (70) in which an introduction space (78) for introducing inflowing refrigerant from a lower end side surface and a distribution space (75) for distributing the refrigerant are formed; and plural connecting passages (88A to 88L) that guide the refrigerant to the plural supply spaces (86A to 86L). A first flat tube (63A1) communicating with a lowermost-tier supply space (86A) positioned on the lowermost side is disposed in a height position included in a height range of the introduction space (78), and a lowermost-tier connecting passage (88A) that guides the refrigerant to the lowermost-tier supply space (86A) is disposed in a position higher than the introduction space (78).

This heat exchanger (2) comprises: - parallel plates (11, 12) which define liquid-refrigerant passages (20) following a longitudinal direction (X), and - fins (21, 22, 23, 24) extending in each passage (20) in a lateral direction (Y) orthogonal to the longitudinal direction (X), each fin (21, 22, 23, 24) having orifices for the flow of the liquid refrigerant. At least one lower portion of at least one fin (21, 22, 23, 24) defines, with the plate secured to this lower portion, a distribution channel for channelling the liquid refrigerant in the lateral direction (Y). The orifices in said at least one fin (21, 22, 23, 24) are formed by overflow openings in the upper portion. The liquid refrigerant flows through the overflow openings when the or each distribution channel is full of liquid refrigerant.

Described is a radiant body (1) comprising a plurality of base modules (10) which are contiguous and with a mutual centre-to-centre distance (C), to form the radiant body (1) having a length (L) and a pair of monolithic junction bodies (20, 21), with a tubular cross-section, for the support, above and below, and for the connection in a sealed fashion of the base modules (10); each junction body (20, 21) engaging a corresponding first (14) or second (15) head of each module (10) at two upper paths (16, 17) of the base modules (10) arranged side by side; each junction body (20, 21) is hollow inside and provided with a plurality of radial openings (30) positioned along the relative cylindrical surface, at a distance (D) from each other equal to the centre-to-centre (C) of the base modules (10); the openings (30) are positioned, in use, facing the central lower third path (18).
摘要:
The present invention relates to a heat exchanger (50) comprising a plurality of plates (10, 20) provided with a planar peripheral area (19, 29), an internal area provided with sinusoidal undulations (13, 23, 14, 24) and two chimneys (11, 21, 12, 22) positioned at two opposing corners of said plates (10, 20). Modules (30) are formed by the assembly of two plates (10, 20) which are in engagement at the troughs (14, 24) of said undulations and at said peripheral areas (19, 29). The modules (30) are stacked such that the inlet (11, 21) and outlet (12, 22) chimneys are in engagement. Each module (30) may thus be deformed independently, in particular in the region of the troughs (14, 24) and peaks (13, 23) of said undulations, without transmitting stresses to the other modules (30) of said exchanger (50). In addition, said exchanger (50) may comprise a tie (40) in each inlet (53) and outlet (54) pipe in order to resist the static pressure of the fluids circulating in said pipes (53, 54).
