The invention relates to a device, comprising at least one flow chamber (20′) having an inlet opening and an outlet opening, said flow chamber being provided for the flow of a medium therethrough. The flow chamber (20′) is arranged in a single-piece block element (2) and is at least partly delimited by a diathermal wall in order to effect absorption or release of thermal energy through the wall by means of the medium. The at least one flow chamber (20′) is formed in the block element (2) from a plurality of first channels (22) spaced apart from each other, which extend straight and parallel to each other, and a plurality of second channels (23) spaced apart from each other, which extend straight and parallel to each other, the first and the second channels (22, 23) each having two ends and being closed at least at one (27) of the two ends. The second channels (23) are arranged at an angle to the first channels (22), the first channels and the second channels thus crossing. Support pillars (21) having a parallelogram-shaped cross-section are present within each flow chamber (20′) between the crossing points of two adjacent first channels (22) and two adjacent second channels (23). A turbulent flow of the medium can be produced very effectively in the device according to the invention.

Two ends of the first mounting shell are hermetically connected to the mounting end plates by brazing. The first mounting shell encloses part of the heat exchange core in a circumferential direction. Two ends of the cover are hermetically connected to the mounting end plates by bonding. The cover and the first mounting shell are arranged in an enclosing manner in the circumferential direction. The heat exchanger improves stability and reliability. A manufacture method of the heat exchanger is also disclosed.

An end-piece for a plate heat exchanger comprises a frame part having an inner portion, an outer portion and an intermediate portion arranged between the inner and outer portions. An outer wall surface of the inner portion faces a first surface of a package of heat transfer plates comprised in the plate heat exchanger. The first surface has a center portion and a peripheral portion encircling the center portion. The frame part is extruded and the intermediate portion of the frame part comprises a first number of cavities extending in an extrusion direction of the frame part. The extrusion direction is parallel to an axis of the frame part. Further, outer dimensions of the outer wall surface of the inner portion are at least as large as outer dimensions of the center portion of the first surface of the package of heat transfer plates.

Systems and methods for using spring force based compliance to minimize the bypass liquid flow gaps between the tops of chip microfins and bottom side of manifold ports are disclosed herein. A fluid delivery and exhaust manifold structure provides direct liquid cooling of a module. The manifold sits on top of a chip with flow channels. Inlet and outlet channels of the manifold in contact with flow channels of the chip creates an intricate crossflow path for the coolant resulting in improved heat transfer between the chip and the working fluid. The module is also designed with pressure reduction features using internal leakage flow openings to account for pressure differential between fluid entering and being expelled from the module.

Heat exchanger (1) for a refrigerant fluid loop, the heat exchanger (1) comprising at least one outlet (6) configured to allow a refrigerant fluid (100) to exit the heat exchanger (1), the heat exchanger comprising a core (34) and a tank (7), that comprises said outlet (6), and the heat exchanger (1) comprising at least one filter (2), characterized in that the filter is adapted to filter (2) the refrigerant fluid (100) that exits the tank (7) and in that said filter (2) is flat. The present invention proposes various arrangements in order to integrate the filter (2) within the heat exchanger (1), including and not limited to the attachment of a connection block (3), housing the filter (2), to the heat exchanger (1).

A liquid-cooling heat dissipation structure includes a substrate and a cover body mated with the substrate to define a heat exchange chamber therebetween. A radiating fin unit and a stop section are disposed in the heat exchange chamber. The stop section serves to first divide a cooling liquid entering the heat exchange chamber, whereby the cooling liquid first flows through the periphery of the radiating fin unit and then flow into the middle of the radiating fin unit so that the cooling liquid is prevented from straightly passing through the radiating fin unit. Multiple cooperative flow-stopping protrusions are disposed in the periphery of the radiating fin unit to help the cooling liquid to uniformly flow through the radiating fin unit. By means of the structural design of the liquid-cooling heat dissipation structure, the heat exchange efficiency is greatly enhanced.
