The invention concerns a cooling device (21) extending circumferentially around a turbo machine housing, such as a turbine housing, having at least one cooling module (30a, 30b, 30c) comprising a tube holder (31, 32) having at least one plate, preferably a radially inner plate (31) and a radially outer plate (32) fixed to each other, the tube holder (31, 32) defining at least two axially spaced housings (34a), each housing (34a) receiving a tube (23) and a sleeve (38) mounted around each tube (23), each tube (23) extending circumferentially around the housing, each cooling module (30a, 30b, 30c) having first fastening means capable of firmly holding its tube holder (31, 32) with respect to the housing, the fixing means comprising at least one spacer (41) having a radially inner end intended to bear against the housing and a radially outer end bearing on the single or on one of the sheets of the tube support (31, 32).

In accordance with one aspect of the present disclosure, a tubular membrane heat exchanger module is provided that includes an inlet header and outlet header. The inlet header is configured to connect to an adjacent upstream tubular membrane heat exchanger module and from an upstream wetted compartment therewith. The outlet header is configured to connect to an adjacent downstream tubular membrane heat exchanger module and form a downstream wetted compartment therewith. The tubular membrane heat exchanger module further includes tubular membranes connecting the inlet header and the outlet header. The tubular membranes facilitate flow of process fluid from the upstream wetted compartment to the downstream wetted compartment. Further, the tubular membranes permit mass transfer between the process fluid in the tubular membranes and a fluid contacting outer surfaces of the tubular membranes.

A baffle for a fluid collection portion of a thermal transfer device can include a body having an inner perimeter, an outer perimeter, and an asymmetric feature, where the asymmetric feature is configured to create a pressure drop within the fluid collection portion of the thermal transfer device. The inner perimeter can be configured to be at least as large as an inner surface of a first wall that forms the fluid collection portion of the thermal transfer device. The outer perimeter can be configured to be no larger than an outer surface of a second wall that forms the fluid collection portion of the thermal transfer device.

A refrigeration unit having an evaporator tube, a heater tube in a spaced relationship with the evaporator tube, a wire that couples the evaporator tube to the heater tube, and a bracket having a first panel configured to contact the heater tube and a second panel that defines a recess configured to receive the heater tube therein.

A vehicle condenser in which a notch portion of each coupling part of a pair of supports installed at the outermost sides of radiation fins extends so as to have a certain length from the tip of a body part to the inside end of the notch portion, or a through-hole is formed so as to be spaced by a predetermined distance toward the inside of the body part from the tip thereof, thereby preventing the radiation fins from melting when the clad on a header of a header tank is melted during the brazing of the radiation fins and flows along an embossing part, regardless of a method for manufacturing the supports. Consequently, it is possible to reduce the failure rate of the condenser and increase the efficiency of the condenser by maintaining the original state of the radiation fins.

The present disclosure relates to a heat exchanger. The heat exchanger includes: a plurality of tube panels including a tube elongated in one direction; a pair of header modules coupled to both ends of the plurality of tube panels; and a pair of header cases having an open side, providing a space therein, and having the header module inserted in the space such that the tube panels communicate with the spaces, in which the header modules is composed of a plurality of header blocks stacked and coupled to each other, and an insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks. Accordingly, it is possible to increase the efficiency of manufacturing a heat exchanger, manufacture a heat exchanger flexibly in a custom-made type in accordance with the size of a product having the heat exchanger, reduce tolerance due to brazing, and improve stability of a product.

A heat exchanger assembly has a frame including first and second legs laterally spaced apart, a lower transversal member extending laterally and interconnecting the legs, first and second upstanding members laterally spaced apart and extending upwardly from the lower transversal member, an upper transversal member extending laterally and disposed above the lower transversal member and connected to the first and second upstanding members, and first and second upper retaining members laterally spaced apart and being connected to the upper transversal member and extending transversally to the upper transversal member. First and second heat exchanger panels are connected to the first and second upper retaining members. The heat exchanger panels are disposed in a V-configuration such that a distance between upper ends thereof is greater than a distance between lower ends thereof. A fan has a fan rotation axis extending generally parallel to the first and second upstanding members.

A heat exchanger having a first heat transfer tube with a first primary straight part and a first secondary straight part is provided. The heat exchanger includes a first primary bond part and a first secondary bond part. The first primary bond part is welded to the first secondary bond part to form a first primary bond that bonds the first primary straight part and the first secondary straight part of the first heat transfer tube. The first primary bond limits a first primary aperture and a first secondary aperture formed by the holes of the bond parts, wherein the straight parts of the first heat transfer tube extend through the first primary bond via the apertures.

A heat exchanger includes a shell to which a secondary heat medium is configured to be supplied and a plate fin coil body provided in the shell. The plate fin coil body includes a plurality of plate fins and a coil which passes through the plurality of plate fins and through which a primary heat medium is configured to flow.

In a method of manufacturing a heat exchanger for a rotating electrical machine, a pressing device is placed inside a tube with elastic members compressed so that a first pressing part and a second pressing part press the tube mutually oppositely in directions in which the diameter of at least a part of the tube located between two through holes of two supporting members expands. Pressure is built up in the tube and the tube is plastically deformed to form an inside large diameter part and inside connecting parts.
