A tube sheet for a shell and tube heat exchanger. The tube sheet includes a substrate having a plurality of through holes; a plug made of a plug material located in each through hole, each plug having a through passage shaped to receive an end of a corresponding tube from the heat exchanger; and a lining made of a lining material, the lining encapsulates the substrate and fills a gap between each plug and the substrate.

A heat exchanger, comprising: a tube bundle having at least one tube for receiving a fluid medium, wherein the at least one tube is wound about a core tube which extends along a longitudinal axis, and a first tube section of the at least one tube rests against at least one web which extends along the tube core and at least one first bracket element for securing the first tube section to the at least one web, the at least one first bracket element having a lower face which faces the first tube section and rests against the first tube section. The invention additionally relates to a securing system and to a method.

The disclosure relates to fin inserts for heat and mass exchangers and corresponding methods. For instance, in some examples, a fin insert to a heat and mass exchanger includes a generally rigid, longitudinally-extending member that includes a top portion and side portions. The side portions may be disposed on opposite sides of the top portion, and may include a concave shape facing away from one another. The side portions may further are each be positioned around a portion of a respective heat transfer tube.

A heat exchange tube and a heat exchanger are provided. A tube wall of the heat exchange tube includes a first wall and a second wall, a first segment of the first wall includes one of a first groove or a first protrusion, a second segment of the first wall includes one of a second groove or a second protrusion, a first segment of the second wall includes the other one of the first groove or the first protrusion, the first protrusion is arranged in the first groove, the second segment of the second wall includes the other one of the second groove or the second protrusion, and the second protrusion is arranged in the second groove. At least part of each of the first segment and the second segment of the first wall is arranged between the first segment and the second segment of the second wall.

A heat dissipation structure has a heat dissipation base and at least one heat conduction assembly mounted in a through hole of the heat dissipation base. Each of the at least one heat conduction assembly includes a resilient clamp and a heat pipe. When a transceiver is inserted in the through hole of the heat dissipation base, two heat conducting sections of the heat pipe are pushed by the resilient clamp to abut against the transceiver and the heat dissipation base respectively. Heat generated while the transceiver is operating can be quickly and efficiently conducted through the heat pipe to the heat dissipation base and then dissipated. Temperature increase of the transceiver can be effectively avoided and performance and reliability of the transceiver during operation can be ensured.

A crimping frame or crimping base for a charge air cooler may include a circumferential raised rim including a plurality of crimping slots. The plurality of crimping slots may each include two longitudinal sides and two narrow sides. The two longitudinal sides may be disposed opposite one another and may extend parallel to the rim. The two narrow sides may be stiffened via a bent reinforcement. The bent reinforcement and the rim may be structured as a single piece.

A support assembly for attaching a heat exchanger to a frame of a machine. The support assembly includes a clip configured to at least partially surround a perimeter of a tube member of the heat exchanger. The clip includes a first end portion and a second end portion configured to engage the first end portion to hold the support assembly around the tube member in a closed position. The first end portion includes a laterally-extending projection and a laterally facing surface spaced apart from the projection by a recessed area. The second end portion defines a recess configured to receive a portion of the projection.

A heat exchanger system may have a base, a mounting apparatus for attaching the base to a device, a gasket shelf for placing a gasket, a dissipation member for dissipating heat, and heat generator attachment sites for absorbing heat. A mounting apparatus may have finger-like extensions which flex and draw the base into contact with an underlying electronic device from which the system conducts heat. A base may also have an integrated heat pipe clamp attachment forming an aperture in the base into which a heat pipe may extend and may be clamped in thermal communication. The dissipation device may be a series of fins and troughs and a fan may direct air over the dissipation device to cool the apparatus.

A header for a heat exchanger includes a header frame defining an opening and including a base portion circumscribing a perimeter thereof. A mounting tab extends from the base portion. The mounting tab is configured to bend inwardly with respect to the header frame. A deformation featured is formed on one of an inner surface and an outer surface of the header frame and is configured to facilitate bending of the mounting tab

A temperature plate includes a plate body and a supporting structure. The plate body has a first plate and a second plat, and a vacuum chamber is defined by the first plate and the second plate. The first plate has a first surface away from the vacuum chamber. The plate body is bent to form a bent portion with the first surface to be a compressive side, and the supporting structure is disposed corresponding to the bent portion. This configuration can prevent the deformation as bending the temperature plate and enhance the heat dissipation performance. In addition, a heat dissipation device adapting the temperature plate is also disclosed, and the heat dissipation device further includes a cooling fin assembly disposed on the first surface of the plate body.
