According to one embodiment, a cooling device includes a heat releasing element including a surface configured to contact a heat generating element and an internal fluid channel configured to flow a cooling medium. The cooling device also includes a plurality of cooling fins within the fluid channel, each of which extends in a direction crossing a flow direction of the cooling medium and has a zigzag, corrugated shape defined by multiple bent portions.

A tank for a heat exchanger includes an extruded tank section having a generally constant extrusion profile extending in a longitudinal direction from a first tank end to a second tank end. A first planar end cap is joined to the extruded tank section near the first tank end, and a second planar end cap is joined to the extruded tank section near the second tank end. Together, the extruded tank section and first and second end caps can at least partially define an internal tank volume. The first and second planar end caps are both arranged at non-perpendicular angles to the longitudinal direction.

A hydronic panel and system for heating and/or cooling a room is disclosed. The hydronic panel includes a plurality of contiguous channels. A first chamber is located at a first end, preferably the upper end, of the panel and includes an inlet and communicates with a first subset of the channels. A second chamber is located at an opposite end of the panel and communicates with the first subset and also with a second subset of the channels. A third chamber is located at the first end of the panel, the third chamber communicates with the second subset of the channels and includes an outlet. In this configuration, heated or cooled water flows from the inlet into the first chamber, through the first subset of the channels, to the second chamber, through the second subset of the channels, into the third chamber and out the outlet. Consequently, the heated or cooled water can heat or cool the space. In addition to at least one hydronic panel, the system includes a source of heated and/or cooled water under sufficient pressure to cause the water to flow through the panel. The system also includes a controller to control one or both of the temperature of the water and the flow rate of the water through the panel.

A dual heat transfer assembly includes upper and lower heat transfer elements received in a separator channel of a port separator of a receptacle cage. The upper heat transfer element includes an upper thermal interface extending into an upper module channel to interface with an upper pluggable module. The lower heat transfer element includes a lower thermal interface extending into a lower module channel of the receptacle cage to interface with a lower pluggable module. The heat transfer elements include inner ends located in the separator channel. The heat transfer elements include biasing members engaging the heat transfer elements and biasing the heat transfer elements into thermal engagement with the pluggable modules.

Disclosed herein is a distributor comprising a first conduit; where the first conduit has an inlet port for charging a heating fluid into the distributor; a second conduit; where the first conduit lies inside the second conduit to define a first annular space therebetween; where the second conduit has an exit port for removing the heating fluid from the distributor; a plurality of plate stacks disposed around the second conduit to define a narrowing second annular space from top to bottom of the distributor; where each successive plate stack has smaller inner diameter than the plate stack located above it; where each plate stack comprises a plurality of plates; where the plurality of plates further define a plurality of conduits, each conduit having a varying width over its length and extending radially outwards from the central passage.

A core arrangement for a heat exchanger includes a first core layer. The first core layer includes first upstream and downstream ends, first and second parting sheets parallel to one another, and a plurality of adjacent fins disposed between the first and second parting sheets. Each of the plurality of fins extends from a surface of the first parting sheet to a surface of the second parting sheet, and longitudinally between the first upstream end and the first downstream end. The plurality of fins are further laterally arranged to define a plurality of first fluid passages. Each of a subset of the plurality of fins includes an internal slot positioned away from the first upstream end and the first downstream end.

A heat exchanger suitable to be used as a recuperator in a micro gas turbine including a stack of cells. Each of the cells includes a pair of mutually spaced-apart plates and layers including heat exchange elements arranged at the outer surfaces of the plates and between the plates. Each of the layers including heat exchange elements can include at least one discrete spatial component incorporating a number of elements. Both a supply header and a discharge header of the heat exchanger can be made of only two components at the position of the stack of cells. Compensating for heat expansion effects can be via a bellows-shaped pipe portion of a supply conduit.

A boiling cooler includes a boiling part, a condensing part arranged in a substantially horizontal direction with respect to the boiling part, and a connecting pipe that connects the boiling part to the condensing part. The condensing part includes a plurality of stages of refrigerant passages, a first external passage provided between the refrigerant passages, and a second external passage provided on an outer surface of at least one of an uppermost refrigerant passage and a lowermost refrigerant passage.
