A heat exchanger for battery cooling is provided to improve an efficiency of cooling of the current heat exchangers. The heat exchanger for battery cooling comprises an upper housing with a fluid inlet and a fluid outlet, a lower housing capable of hermetically connecting with the upper housing to form a chamber for accommodating fluid. The fluid flows into the chamber through the fluid inlet and then exits through the fluid outlet. The fluid chamber is provided with at least one S-shaped fluid directing element with several through holes. With the S-shape directing elements within the fluid chamber and the through holes formed on the directing elements, fluid can flow in an injecting manner within the chamber to realize effective cooling of the upper housing.

The invention relates to a battery housing (1) for a vehicle driven by an electric motor, which is to be installed in the floor region of a vehicle, having a frame (2), which encloses at least one battery module, and a floor (3), which is connected to the frame (2), The floor (3) takes the form of a sandwich construction and forms hollow chambers (18, 18′), which can be used as temperature-control channels for guiding through a fluid by virtue of end-side openings in adjacent hollow chambers (18, 18′) being connected to one another at their two ends.

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.

A heat exchange structure includes a primary heat exchange body with a first fluid channel fluidly separated from a second fluid channel by a barrier channel, an inlet manifold in fluid communication with the first fluid channel, and a secondary heat exchange body. The secondary heat exchange body is in fluid communication with the barrier channel, is arranged within the inlet manifold, and fluidly couples the barrier channel to the external environment. Fluid systems and heat exchange methods are also described.

A multi-component fluid delivery system includes a heater system. The heater system includes an improved fluid preheating system based on a high conductivity fluid heat exchange manifold that is coupled to external heater elements (e.g., powered via electricity). These techniques can provide more surface area for heating fluid and is external to the fluid passages, making service or replacement much easier. These techniques can utilize etched foil or wire wound heater elements that operate at a lower internal temperature than cartridge heaters, and thus can be inherently more reliable.

A falling film of liquid desiccant in direct contact with a gas stream is formed, which allows water vapor transfer between a gas stream (air) and the desiccant, enabling dehumidification and/or humidification of air. Thin films are created in one way by a wettable layer that is in contact with a support structure and in another way directly on the support structure. The devices can be installed on an absorber (conditioner) side or a desorber (regenerator) side or both of air conditioning systems; for example, liquid desiccant air conditioning (LDAC) applications.

A heat exchanger for an aircraft engine that allows improvement in heat exchange ratio is provided. The heat exchanger (1) includes a plurality of heat dissipating fins (20, 30). The plurality of heat dissipating fins (20, 30) are arranged on at least one of a surface (2) and a surface (3). Each of the heat dissipating fins (20, 30) has a plate-like shape and has an inlet-side upper edge disposed on the side where a swirl flow (AF1) flows in and an outlet-side upper edge disposed on the side opposite the inlet-side upper edge and on the side where the swirl flow (AF1) flows out, and the inlet-side upper edge intersects the axis of rotation of a fan and extends along the direction in which the swirl flow (AF1) flows at the inlet-side upper edge.

A pin for a heat exchanger. The pin includes: a monolithic top section; a monolithic bottom section; and a middle section comprising a plurality of spaced apart sub-pins extending between the top section and the bottom section, wherein the plurality of sub-pins define one or more windows for allowing fluid flow through the middle section. Also disclosed is a layer of a heat exchanger including the pin, as well as a heat exchanger including the layer, and a method of making a layer for a heat exchanger.

A surface type air to oil cooler enables oil to flow from an inlet and down a first pass of an oil passageway. A first bypass, before the end of the first pass, allows oil to flow from the first pass to a second pass of the oil passageway. A second bypass may exist toward the end of the second pass to allow the oil to flow from the second pass to an outlet before the end of the second pass.

A plate heat exchanger and methods of construction and use which allow the plate assemblies used in the exchanger to be easily cleaned and maintained and which allow the plate assemblies to be individually and separately removed from the exchanger for cleaning or maintenance while the exchanger remains online and while the other plate assemblies in the plate heat exchanger continue to operate.
