The present invention relates to a plate heat exchanger comprising a plate package and a manifold both made of metal. The plate package comprises a plurality of heat exchanger plates stacked between end plates. The heat exchanger plates being sealed to each other and form alternating first plate interspaces for a first medium and second plate interspaces for a second medium. The plate package defines at least two port channels communicating with the first plate interspaces. At least one of the end plates define connection ports communicating with a respective port channel. The manifold defines a port opening, a distant opening and a flow passage extending between the port opening and the distant opening. The manifold being fixedly attached to one of the end plates such that the port opening of the manifold covers one of the connection ports. The manifold being made by additive manufacturing, moulding or casting.

The first and second media are coupled via evanescent waves generated by surface phonon polaritons thermally excited on surfaces of the first and second media. First and second media made of the same material are disposed with a gap formed between for cutting off thermal conduction and the heat transfer between them is performed via the thermally excited evanescent waves. A third medium is provided on a surface of the first medium on a side toward the second medium. Heat flux flows from the second medium to the first medium in a first state wherein the second medium has a first temperature T.sub.H and the first medium has a second temperature T.sub.L lower than the T.sub.H differ in intensity from heat flux which flows from the first to the second medium in a second state wherein the first medium has the T.sub.H and the second medium has the T.sub.L.

A heat exchange device has a heat transfer member having thermal conductivity and a fin that is provided integrally with the heat transfer member. A heat transfer is performed between the heat transfer member and the fin. The fin is configured by more than one of a carbon nanotube aggregate that is configured by carbon nanotubes assembled together. The carbon nanotube aggregates are arranged on the heat transfer member and distanced from each other, and protrude from the heat transfer member in an axial direction of the carbon nanotubes.

A thermal interface material (TIM) using high thermal conductivity nano-particles, particularly ones with large aspect ratios, for enhancing thermal transport across boundary or interfacial layers that exist at bulk material interfaces is disclosed. The nanoparticles do not need to be used in a fluid carrier or as filler material within a bonding adhesive to enhance thermal transport, but simply in a dry solid state. The nanoparticles may be equiaxed or acicular in shape with large aspect ratios like nanorods and nanowires.

According to an aspect, a flow path component includes a flow path component body having a flow surface. The flow path component also includes a plurality of antimicrobial nanoparticles embedded in the flow surface and at least partially exposed external to the flow surface to provide an antimicrobial surface.
