摘要: A heat transfer surface for use in conjunction with a heat exchanger is disclosed. The heat transfer surface a corrugated member where rows of corrugations that are offset relative to each other forming at least an alternating series of first and second rows or first, second and third rows. In some embodiments the heat transfer surface includes a heat transfer enhancement feature disposed within individual corrugations of the corrugated member to provide a more turbulent or tortuous fluid flow path through the heat transfer surface. In some example embodiments the heat transfer enhancement feature is a ridge disposed in the planar portions of at least some of the rows of corrugations. In other example embodiments the planar fin portions are porous fin surfaces. In other embodiments, the corrugated member cooperates with heat transfer enhancement features in the form of triangular protuberances disposed on their inner surfaces of spaced apart plates.

摘要: There is provided an electronic apparatus that includes a heat radiation unit capable of radiating heat efficiently from a heat pipe. The electronic apparatus includes: a blower fan that blows air toward an exhaust port formed in a main body chassis; a heat radiation fin provided in an air-blowing outlet of the blower fan; and a heat pipe fixed to the heat radiation fin. In a region in contact with the heat pipe, the heat radiation fin is of a partial connection structure in which multiple fin members are partially fixed and connected to one another, and in a region with no contact with the heat pipe, the heat radiation fin is a structure of continuous fins.

摘要: A heat exchanger has a turbulating insert arranged between a pair of plates. The turbulating insert is permeable to fluid flow in both a high-pressure-drop direction and a low-pressure drop direction. One portion of the turbulating insert has the high-pressure-drop direction oriented at a non-zero angle to the high-pressure-drop direction of another portion. A method of making the heat exchanger includes forming a turbulating insert, removing a portion of the turbulating insert to create a cavity within the turbulating insert, placing the remaining turbulating insert into a stamped first plate, and placing the removed portion of the turbulating insert into the cavity at a non-zero angle of rotation relative to the remaining turbulating insert.

摘要: An air cooled condenser fin comprises flow channel walls defining an air flow channel. The flow channel walls include planar sections separated by intermittent flow interruptions which are spaced apart along the air flow channel. The intermittent flow interruptions are defined by the flow channel walls. The intermittent flow interruptions may for example comprise splits formed by a staggered arrangement in which the planar sections of the flow channel walls before and after each split are staggered; or intermittent sinusoidal waves formed into the flow channel walls; or louvers formed into the flow channel walls to create openings passing through the flow channel walls at the louvers. The intermittent flow interruptions may be spaced apart along the air flow channel by at least 5 hydraulic diameters, and in some embodiments by 5-10 hydraulic diameters. A plurality of such air cooled condenser fins are suitably employed with the air flow channels arranged in parallel.

摘要: A heat dissipating module with micro-passages includes a heat dissipating cavity connecting to a top of a heat absorbing cavity to form a distance from a heat source. When a working fluid in the heat absorbing cavity absorbs the thermal energy and is vaporized, the vapor would flow up to a vapor guiding space due to thermosyphon effect and principles of Boyle's Law, and then the vapor is projected and spread rapidly and evenly to the heat dissipating cavity through a projecting exit. Then the vapor is condensed into liquid and become the working fluid again by heat exchange. The condensed liquid then drips down and flows back to the heat absorbing cavity via micro-passages, forming a cycle of phase change of the working fluid for operation of heat dissipation.

摘要: A heat exchanger includes one or more hot medium flow regions and one or more cooling medium flow regions. Hot medium bars border the one or more hot medium flow regions and cooling medium bars border the one or more cooling medium flow regions. At least one cooling medium bar of the cooling medium bars is joined to a pair of partition sheets. The at least one cooling medium bar includes a base, a first leg, and a second leg. The first leg and the second leg each extend from the base. A cavity is provided between the first leg and the second leg. The cavity is in fluid communication with a first cooling medium flow region of the one or more cooling medium flow regions via an opening provided between the first leg and the second leg.

摘要: The present invention provides a plate-fin heat exchanger core and a fin structure thereof. The plate-fin heat exchanger core includes: a plurality of partition plates and a fin, where the fin is supported and fixed between two adjacent partition plates; the two adjacent partition plates are sealed to form a fluid channel unit; the fluid channel unit forms a plurality of heat exchange channels for a medium to flow between the adjacent partition plates; the fin is provided with a plurality of dimples/protrusions; the dimple/protrusion is provided with a perforated hole to form a perforated dimple/protrusion. The fin increases the heat exchange area, and the dimple/protrusion structure improves the pressure-bearing capacity of the plate-fin structure and improves fluid turbulence, thinning a flow boundary layer and a hot boundary layer.

摘要: A heat exchanger may include a perforated plate having a plurality of openings sandwiched between a first plate and a second plate. The first plate may have a first plate central planar surface, a first plate peripheral wall extending from an internal face of the first plate central planar surface towards the second plate, and an inlet permitting fluid flow on to the internal face of the central planar surface. The second plate may have a second plate central planar surface, a second plate peripheral wall extending from an internal face of the second plate central planar surface towards the first plate, and an outlet permitting fluid to exit the heat exchanger. The first plate, the second plate and the perforated may be coupled and define a fluid passage for flow of a heat exchanger fluid from the inlet to the outlet.
