A data plate assembly for installation with a plate heat exchanger. The data plate assembly includes a monitoring device assembled with a spacer plate. The spacer plate includes inlet and/or outlet holes, and a port that extends from an outer edge of the spacer plate to one of the inlet and/or outlet holes. The port retains the monitoring device therein such that the monitoring device extends into the inlet and/or outlet holes to monitor characteristics of the process and cooling fluids flowing through the holes and the plate heat exchanger. As the performance of the plate heat exchanger degrades, the characteristics accumulated over a period of time may provide an indication that the performance of the plate heat exchanger is degrading and/or the rate in which the performance of the plate heat exchanger degrades.

A thermal diffusion unit is fluidly connected to a combustion engine via a flue line. The thermal diffusion unit has a plurality of plates assembled in a parallel configuration, including a pair of heating plates having a heating fluid gap extending therebetween and a pair of cooling plates having a cooling fluid gap extending therebetween. A diffusion sheet is positioned between the pair of heating plates and the pair of cooling plates, such that the diffusion sheet interfaces on a first side with one of the heating plates and interfaces on an opposite side with one of the cooling plates. The diffusion sheet includes a plurality of interconnected thermal diffusion cells arranged in a repeating pattern, at least one heated passage fluidly connecting adjacent thermal diffusion cells, and at least one cooled passage fluidly connecting adjacent thermal diffusion cells.

Potentially off-grid grain conditioners that can be operably connected to an aeration grain bin or silo to blow heated air through the crop to dry the crop or to blow ambient temperature air through the crop to cool it are disclosed. A fan is powered by a motor that may be mounted inside the air stream to allow the heat from the motor to be collected and forced into the airstream that is blown into the grain bin. The engine exhaust may be routed through an air exchanger to remove heat from the exhaust and direct heat into the grain bin, or the exhaust may be put into the atmosphere without capturing any of the heat, which allows the fan to operate in a cooling mode. The motor may be mounted inline or mounted to the side for a centrifugal aeration fan.

A heat exchanger includes a body having an inlet header through which a fluid is introduced, and an outlet header through which the fluid is discharged; and one or more plates accommodated in the body and provided with flow path modules providing flow paths for the fluid introduced through the inlet header to flow to the outlet header. The heat exchanger further includes at least one flow path adjuster each having at least a portion thereof accommodated in the body and being movable or rotatable to open or close a part or all of the flow paths or to change directions of the flow paths so that a flow of the fluid is adjusted.

A two-pass heat exchanger with calibrated bypass is disclosed for cooling heat-generating substrates and/or for heating a heat transfer fluid. The heat exchanger has first and second outer plate walls and an intermediate plate wall located between and spaced from the outer plate walls in the thickness dimension of the heat exchanger, and with inlet and outlet ports at the same end. An input flow passage is defined between the first outer plate wall and the intermediate plate wall, and a return flow passage is defined between the second outer plate wall and the intermediate plate wall. The first and second fluid flow passages are in a U-flow, stacked arrangement. At least one bypass opening extends through the intermediate plate wall between the input and return flow passages, and configured to permit a portion of the heat transfer fluid to bypass portions of the input and return flow passages.

A flow path tube of a heat exchanger includes an inner fin having a meander shape in which a one-side top part and an other-side top part are alternately arranged via an intermediate part. The intermediate part includes a communication part with a communication port that communicates the adjacent fine flow paths. A one-side wall part is extended from the one-side top part, which is adjacent on one side, to the communication part and separates the adjacent fine flow paths. An other-side wall part is extended from the other-side top part, which is adjacent on the other side, to the communication part and separates the adjacent fine flow paths. An edge of the one-side wall part is formed such that an edge of the other-side wall part is shifted in parallel in the longitudinal direction of the flat cross sectional shape of the flow path tube.

A heat exchanger includes: a first layer including first flow channels that are microchannels and arranged to extend side by side; and a second layer that is laminated on the first layer and that includes second flow channels that are microchannels and arranged to extend side by side. A first one end-side collective flow channel is in fluid communication with first ends of the first flow channels. A first other end-side collective flow channel is in fluid communication with second ends of the first flow channels. A second one end-side collective flow channel is in fluid communication with first ends of the second flow channels. A second other end-side collective flow channel is in fluid communication with second ends of the second flow channels.

The present disclosure relates to the technical field of heat exchange devices, and in particular, to a plate, a plate assembly and a heat exchanger. The plate comprises a plate body and a first through hole and a second through hole provided on the plate body; the plate body forms a pipe segment around the first through hole, and the second through hole is arranged close to the outer periphery of the pipe segment.

A plate heat exchanger comprising a top head, a bottom head, four side panels and four corner girders. The side panels and the corner girders extend along a longitudinal direction from the bottom head to the top head, and each side panel is associated with two corner girders. The top head, the bottom head, the four side panels and the four corner girders are joined together to form a sealed enclosure for housing a plate pack of stacked heat-exchanging plates. A continuous gasket assembly is arranged in a contact region between at least one side panel and two corner girders, the top head and the bottom head. The gasket assembly is located in a groove. Moreover, the gasket assembly is a segmented gasket assembly composed of plural gasket segments, and each gasket segment is made of graphite material. Also disclosed is a method for assembling such a plate heat exchanger.

A plate for a heat exchanger has a longitudinal centerline, a reference plane parallel to the longitudinal centerline, and multiple corrugations provided in the plate that define flow channels through which fluid flows. The corrugations extend at an angle to the reference plane and at least some of the corrugations are intersected by the reference plane, wherein over at least a portion of a surface area of the plate the corrugations are arranged in sub-regions that have a longitudinal length and the corrugations of each sub region are at the same angle relative to the longitudinal centerline, and the corrugations of adjacent sub-regions are at different angles from each other, and wherein the corrugations in adjacent sub-regions meet at junctions and the junctions are not longitudinally aligned.
