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.

Exfoliated graphite materials, and composite materials including exfoliated graphite, having enhanced through-plane thermal conductivity can be used in thermal management applications and devices. Methods for making such materials and devices involve processing exfoliated graphite materials such as flexible graphite to orient or re-orient the graphite flakes in one or more regions of the material.

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.

A heat sink includes: a base plate; and at least one fin secured to the base plate; wherein the base plate has at least one through hole that extends in a first direction parallel to a surface of the base plate, wherein the at least one fin has a projection inserted into the at least one through hole, and wherein, in a second direction that is parallel to the surface of the base plate and that is perpendicular to the first direction, both end surfaces of the projection are in contact with inner wall surfaces of the at least one through hole entirely in a third direction parallel to a thickness direction of the base plate.

A water cooling radiator includes a water pump assembly and a water drain assembly. The water pump assembly includes a base and a housing spliced with the base to form an accommodating cavity. A water inlet portion and a water outlet portion in the accommodating cavity are formed on the base. The water inlet portion includes a water inlet tank provided on the base, a water inlet pump arranged in the water inlet tank and connected with the base, and a water inlet nozzle connected to the base and communicated with the water inlet tank, The water inlet tank is communicated with the water drain assembly. The water outlet portion includes a water outlet tank provided on the base, a water outlet pump arranged in the water outlet tank and connected with the base, and a water outlet nozzle connected to the base and communicated with the water outlet tank.

A method for manufacturing a counter flow total heat exchanger is disclosed. The method for manufacturing a counter flow total heat exchanger, according to the present invention, comprises the steps of: inserting, between a pair of rollers (210, 210a) having protrusions formed on the surface thereof, a first paper having a first width, so as to form same into a single face corrugated cardboard sheet (T) having flow paths (111c, 121c); attaching the corrugated cardboard sheet (T) to a middle region of a second paper having a second width that is wider than the first width; cutting, into a length corresponding to guide corrugated cardboards (111, 121), the second paper to which the corrugated cardboard sheet (T) is attached; and cutting the second paper by means of a liner (130) having triangular resin tube coupling surfaces (133) formed on both sides of the cut guide corrugated cardboards (111, 121).

A shape-morphing fin includes a fixed portion, a multistable portion, a coupling portion, and a vibration source. The multistable portion functions as a negative stiffness element. The multistable portion is selectively movable between a first position and a second position. The movement between first position and the second position is configured to remove the ice formation from the structure. The coupling portion couples the fixed portion to the multistable portion. The vibration source is configured to produce a resonant vibration to engage the movement of the multistable portion from the first position to the second position.
