摘要： The present disclosure relates to a technical idea of reducing the surface temperature of a material or temperature under a material by emitting heat under a device to the outside by absorbing and emitting long-wavelength infrared light corresponding to the wavelength range of the atmospheric window while minimizing absorption of light of the solar spectrum. More particularly, the present disclosure relates to a technology for providing a radiative cooling device having a multilayer structure that is capable of increasing sunlight reflection through differences in the refractive indexes of the device-forming materials while performing selective emission over the wavelength range of the atmospheric window using a radiative cooling device having a multilayer structure composed of polymers and inorganic materials.

摘要： A heat exchanger includes a bag-like outer packaging material. A heat medium flows into an inside of the outer packaging material. An inner core material is arranged in the inside of the outer packaging material. The outer packaging material has an outer packaging laminate material including a metal heat transfer layer and a resin thermal fusion layer on a surface side of the heat transfer layer. The outer packaging laminate materials form a bag shape by integrally joining the thermal fusion layers along the peripheral edge portions. The inner core material includes the inner core laminate material with a metal heat transfer layer and resin thermal fusion layers on surface sides of the heat transfer layer. The thermal fusion layers of a concave portion bottom and a convex portion top of the inner core material and the thermal fusion layers of the outer packaging laminate material are integrally joined.

摘要： Provided is a radiative cooling device that provides coloration of the radiative surface while maximally avoiding reduction in its radiative cooling performance due to absorption of solar light. An infrared radiative layer for radiating infrared light from a radiative surface and a light reflective layer disposed on the side opposite to the presence side of the radiative surface of the infrared radiative layer are provided in a mutually stacked state. The light reflective layer is arranged such that a first metal layer made of silver or silver alloy and having a thickness equal to or greater than 10 nm and equal to or less than 100 nm, a transparent dielectric layer and a second metal layer reflecting light transmitted through the first metal layer and the transparent dielectric layer are stacked in this order on the side closer to the infrared radiative layer. The transparent dielectric layer has a thickness that causes a resonance wavelength of the light reflective layer to be a wavelength included in wavelengths equal to or greater than 400 nm and equal to or less than 800 nm.

摘要： A counterflow heat exchanger includes a first fluid inlet, a first fluid outlet fluidly coupled to the first fluid inlet via a core section, a second fluid inlet, and a second fluid outlet fluidly coupled to the second fluid inlet via the core section. The core section includes a plurality of first fluid passages configured to convey the first fluid flow from the first fluid inlet toward the first fluid outlet, and a plurality of second fluid passages configured to convey the second fluid flow from the second fluid inlet toward the second fluid outlet such that the first fluid flow exchanges thermal energy with the second fluid flow at the core section. One or more drains are operably connected to the plurality of first fluid passages configured to remove condensation from an interior of the first fluid passages prior to the condensation reaching the first fluid outlet.

摘要： An open mesh member for insertion into a cooling tower utilizing polluted or clean water and counterflow or crossflow airflow includes a plurality of corrugations including upper support frames, lower support frames and a wall strand. The upper and lower support frames extend at a corrugation angle relative to a height axis. The corrugations have a plurality of openings through a thickness of the mesh member. A planar edge positioned at a first end of the mesh member. A beveled edge positioned at a second end of the mesh member. The beveled edge includes a first bevel extending distally from one of the upper support frames. The bevel includes first and second legs and a distal end. The first and second legs extend substantially parallel relative to the associated upper support frame.
