Apparatus and methods for jet impingement cooling are provided. In one arrangement, a fluid channelling structure engages against a target surface to define a flow volume. Fluid is jetted onto the target surface from inlets and is removed via outlets. Flow directing features form a plurality of channels with no straight paths between inlets and outlets. A time averaged flow direction of fluid in contact with each flow directing feature is more nearly perpendicular to a direction of jetting of the fluid from a nearest inlet than parallel to the direction of jetting One or more pairs of the inlets and outlets are such that a majority of fluid jetted onto the target surface from the inlet of the pair will be removed from the flow volume through the outlet of the same pair.

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.

A drying device for processing a gas to be dried, in particular air, comprises an air/air exchanger which includes an inlet for the gas to be dried and an outlet for the dried gas, an evaporator which receives the gas to be dried from the air/air exchanger, the evaporator being formed by means of a plurality of adjacent layers. The layers comprise at least a first layer configured for the passage of a refrigerating fluid, at least a second layer configured to receive the gas to be dried from the air/air exchanger and a plurality of third layers configured to receive a phase change material. The layers are arranged in a sequence which comprises in alternation a first layer, a third layer, a second layer and a further third layer.

A heat exchanger, including at least one flat pipe, each flat pipe is provided with a refrigerant cavity, an inlet, an outlet and two through holes, the inlet and the outlet are located at two ends of the refrigerant cavity, respectively, and both the inlet and the outlet communicate with the refrigerant cavity; the two through holes are respectively located at two ends of the refrigerant cavity, and the two through holes do not communicate with the refrigerant cavity. The flat pipe is provided with the inlet, the outlet and two through holes, when the plurality of flat pipes are matched with liquid collecting pipes (liquid inlet pipes or liquid outlet pipes) of the heat exchanger, different flat pipes can choose to use the inlets or outlets to communicate with the liquid collecting pipes, and the through holes are able to be used to avoid the liquid collecting pipes.

A heat exchanger has at least one inlet and outlet to permit circulation of refrigerant therethrough. Each heat exchanger includes a plurality of thin sections of material arranged between a pair of thin flat outer plates. Each of the thin sections of material is comprised of parallel flow paths, allowing for the refrigerant to flow through the inlet, then from one section to the next, and finally out the outlet. The arrangement of the sections of parallel flow paths allows for the refrigerant to come into contact with the majority of the inside wall of the outer plates, allowing for maximum heat exchange. In use for cooling liquids, the heat exchangers are arranged within a frame and brought into contact with the liquid to be cooled. When the heat exchangers are used to cool liquid sufficiently to produce ice crystals, a rotating scraping device sweeps across the surface of the heat exchanger, removing any ice crystals that have formed.

The invention relates to a heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates (14a, 14b) and fins (16a, 16b) of the heat exchanger, the fluids flowing in a multitude of passage channels (10) each consisting of a closed space (12) delimited by two adjacent plates and two adjacent fins, characterized in that each plate extends along a non-planar surface following at least a first oscillating curve, and each fin further following at least one second oscillating curve along at least one second main direction, in such a way that each passage path allows the fluid to flow in the closed space along a fluid direction defined by a generatrix that is a combination at least of the first oscillating curve and the second oscillating curve.
