The invention relates to a heat exchanger block 2 and to a heat recovery ventilation unit 1 comprising such a heat exchanger block. In the heat exchanger block 2, the individual flow cross-section (Q1) of flow passages of said plurality of first air flow passages (AFP1) in said parallel flow region (PF) and the individual flow cross-section (Q2) of flow passages of said plurality of second air flow passages (AFP2) in said parallel flow region (PF) gradually, preferably linearly, decrease along a straight line (x-perpendicular to the parallel air flow passages (AFP1 and AFP2) and from said first wall (W1) to said second wall (W2) of the block.

A heat exchanger having a first and second mixing devices having at least one lateral channel configured in order for a first phase of the first fluid to flow from at least one first inlet; a series of longitudinal channels extending in the longitudinal direction and each configured in order for a second phase of the first fluid to flow from a second inlet to a second outlet, the longitudinal channels succeeding each other in a lateral direction orthogonal to the longitudinal direction; and at least one opening fluidly connecting the at least one lateral channel to at least one longitudinal channel such that the first and second mixing devices are configured to distribute a mixture of the first phase and the second phase via the second outlets of their respective longitudinal channels.

A layer for a heat exchanger includes: an inlet; an outlet; an upper sheet; a lower sheet; a fluid flowpath defined between the upper sheet and lower sheet and from the inlet to the outlet; and at least one pin disposed in the flowpath and connecting the upper sheet to the lower sheet; wherein the lower sheet has a first undulating profile. The upper sheet has a second undulating profile different from the first undulating profile. Also disclosed is a heat exchanger including the layer, and a method of making a layer for a heat exchanger.

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 partition members, alternately stacked spacing members, and seals. The spacing members include first and second spacing members forming the first and second passages. The first and second spacing members each have a frame portion along a periphery of the partition members. The frame portion of the first and second spacing members have first and second communication sections having first and second communication openings allowing the first and second passages to communicate with outside of the frame portion, and first and second partition walls separating the first and second passages from the outside of the frame portion. The frame portions of the first and second spacing members further have first and second notches provided in portions of the first and second partition walls, and open on an outer side surface of the first and second partition walls. The seals cover surfaces of the first and second notches.

An additively manufactured heat exchanger configured to transfer heat between a first fluid and a second fluid includes a first channel with a first wall configured to port flow of a first fluid and a second channel with a second wall configured to port flow of a second fluid. The heat exchanger also includes a barrier channel containing unprocessed build powder provided by the additive manufacturing process and is located between the first wall and the second wall. The barrier channel is configured to prevent mixing of the first fluid and the second fluid when one of the first wall and the second wall ruptures.

A heat exchanger includes a heat exchanger body having a plurality of layer portions each having a plurality of flow paths, and having a configuration in which adjacent layer portions are joined to each other, an inflow header being configured that a fluid is introduced into the inflow header to flow into the plurality of flow paths, an outflow header being configured that a fluid flowing through the plurality of flow paths merges, a cover portion covering all joint portions of the adjacent layer portions or all joint portions of components of layer portions, the joint portions exposed on an outer surface of the heat exchanger body at a portion other than a portion where the inflow header and the outflow header are disposed, and a lead-out portion connected to the cover portion and forming an internal flow path communicating with a space between the cover portion and the heat exchanger body. The lead-out portion is configured to emit a fluid to a predetermined region set in advance.

A heat dissipator includes a plate-shaped base portion extending in a first direction along a refrigerant flowing direction and in a second direction orthogonal to the first direction and has a thickness in a third direction orthogonal to the first direction and the second direction, and fin groups including fins arranged in the second direction, protruding from the base portion to one side in the third direction and extending in the first direction. One of the fins includes a spoiler with an opposing surface that opposes one side in the first direction that is a downstream side in the refrigerant flowing direction. A number of the spoilers included in each of the fins in a same second direction position in the fin groups increases toward the one side in the first direction.

Planar element adapted to form, when stacked with a plurality of other such elements, a heat exchanger, comprising an inlet region, a first zone adapted to direct flow from the inlet region towards a second zone, a second zone comprising at least one cutout in the plane of the planar element, adapted to accommodate a cooling core, a third zone, adapted to direct flow from the second zone towards an outlet region and an outlet region, the planar element comprising a first blockage protrusion disposed along a first group of said side edges, the first group comprising at least a side edge adjacent to said outlet region, and a second blockage protrusion disposed along a second group of said side edges, the second group comprising at least a side edge adjacent to said inlet region.
