The present invention relates to a plate heat exchanger for treatment of a feed. The plate heat exchanger includes a plate package comprising a plurality of heat exchanging plates and defining a heating volume, a cooling volume and a plurality of process volumes. Each of the process volumes includes an evaporation section for evaporation of a part of the feed, a separation section for separating a non-evaporated part from an evaporated part of the feed, and a condensation section being arranged to condense the evaporated part of the feed. Each heat exchanging plate defines a first thermal interface between the heating volume and the evaporation section of a first process volume, a second thermal interface between the cooling volume and the condensation section of a second process volume, and at least one further thermal interface between an evaporation section and a condensation section of two adjacent process volumes.

A heat sink includes a threaded rod. The threaded rod includes a first portion and a second portion. The first portion may engage with a first heat sink fin and a second portion may engage with a second heat sink fin. The first portion includes a first external thread of a first diameter. The second portion includes a second external thread also of the first diameter and of different pitch than the first external thread. For example, the pitch of a first knurl of the threaded rod may be smaller than the pitch of a second threaded knurl of the threaded rod. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.

The present disclosure relates to a fin heat exchanger, including a header, a set of tubes fluidly coupled to the header, and a mount configured to engage with and disengage from the set of tubes. The mount includes a fin section configured to extend between adjacent tubes of the set of tubes in an engaged mount configuration, and configured to be separated from the set of tubes in an unengaged mount configuration.

A gasket for a plate heat exchanger, the gasket comprising a body in the form of a loop for fitting to a plate of the plate heat exchanger, the body including one or more peripheral connection areas spaced along at least one side of the loop, and a plurality of tabs for securing the gasket in position on the plate, each tab being discrete from the body, and each tab including connection means which is receivable by or engageable with one of the connection areas to connect the tabs and body together.

A heat exchanger includes an inlet for receiving bulk solids, a plurality of heat transfer plate assemblies, a plurality of spacers disposed between adjacent heat transfer plate assemblies, and supports for supporting the heat transfer plate assemblies. The heat transfer plate assemblies include a first plate having a first pair of holes extending therethrough, the first plate having channels extending along a surface thereof, for the flow of fluid through the channels, and a second plate bonded to the first plate to enclose the channels, the second plate including a second pair of holes generally aligned with the first pair of holes to form through holes to facilitate flow of the fluid through the through holes and the channels.

Lining to be positioned in a frame plate of heat exchanger comprising a stack of heat transfer plates, where the lining comprises a tubular part with a first end formed with a first flange and second flange positioned at a distance to the second end, where the second flange is adapted to form a platform to accommodate a sealing element is positioned on the platform of the second flange and this confined between the edge of the recess, the second flange and the outer section and the neighbouring heat transfer plate in the stack of heat transfer plates.

A cooling element system (100), for use within a cooling device (590) of a closed-circuit respirator (691), includes a plurality of cooling elements and a collar (120). The cooling elements each have an element housing (112), having a liquid-tight closure (114), filled or fillable with a coolant. The element housings allow for a common mounting arrangement of the number of cooling elements within the cooling device. The collar encloses the cooling elements in the common mounting arrangement and has a carrying area (122), which is configured to carry the number of cooling elements in the common mounting arrangement at the carrying area. A removal of the number of cooling elements, in the common mounting arrangement, from the cooling device and an insertion into the cooling device, are possible by means of the carrying area.

A heat exchanger plate (2) is described comprising an edge (7), a groove (8) running along the edge (7), a gasket arranged in the groove (8), and a corrugated area (10) having tops (12) and valleys (11) between the groove (8) and the edge (7), wherein tops (12) run substantially perpendicular to the edge (7). In such a heat exchanger plate the gasket should be reliably fixed without affecting the stability of the heat exchanger. To this end, in at least one valley (11) a raised section (14) extends from a bottom area (13) of the valley (11) and the gasket comprises a click-on extension arranged in the valley (11) and having a recess adapted to the raised section (14).

A heat sink includes a first fin and a second fin. The spacing between the first fin and the second fin may be adjusted by a threaded rod. The threaded rod may include a first portion that is engaged with the first fin and a second portion that is engaged with the second fin. The thread pitch of the first portion and the second portion may differ. For example, the pitch of a first internal thread of the first fin may be smaller than the pitch of a second internal thread of the second fin. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.

A heat exchanger stack includes a rack structure and heat exchangers disposed above one another and supported thereby. Each heat exchanger includes: a frame; a tubing arrangement configured to circulate fluid therein; a plurality of fins; and a plurality of wheels mounted to the frame for guided mounting of the heat exchanger panel on the rack structure including first and second upper wheels spaced apart from one another and first and second lower wheels spaced apart from one another. Each upper wheel engages a corresponding upper wheel guiding member of the rack structure, and each lower wheel engages a horizontal portion of a corresponding lower wheel guiding member of the rack structure so that the heat exchanger panel is translatable horizontally. A method for mounting a heat exchanger panel to a rack structure is also provided.
