摘要： A heat exchanger for the thermal coupling of two fluids may include an inflow pipe defining a pipe longitudinal centre axis. A fluid inlet may be arranged on the inflow pipe. A plurality of flat tubes leading into the inflow pipe may be arranged on the inflow pipe adjacent to the fluid inlet. The first fluid stream may be flowable along a first fluid path extending from the fluid inlet through the inflow pipe and the plurality of flat tubes. The flat tubes may extend through a second fluid path for a second fluid stream of fluid and may be flowed about by the second fluid stream during operation. The heat exchanger may further include passage screen aperture interacting with the heat exchanger fluid and through which the first fluid stream is flowable. The passage screen aperture may be fluidically connected in series with the flat tubes.

摘要： Enhancing condensation heat transfer performance in applications including power generation, thermal management of high-performance electronics, water purification, distillation, natural gas processing, and air conditioning can be achieved with heat transfer devices. Condensation heat transfer can be enhanced via a hierarchical structure attached on a condenser surface. This novel hierarchical structure is composed of a thin, highly permeable, thermally conductive porous wick and a highly porous, robust, intrinsically hydrophobic membrane bonded or attached on top of the wick.

摘要： A heat exchanger (10) of heat pipe configuration for transferring heat between a first and second process streams via a heat transfer fluid comprises: at least one first process stream passage (19); at least one second process stream passage (29); and a shell (11) enclosing the first and second process stream passages (19, 29) within a volume (55). The volume (55), as a result of a heat transfer process, is fully filled with both vapour and liquid phases of the heat transfer fluid. The first and second process stream passages (19, 29) are spaced by a disengagement zone (50) enabling gravitational separation of said vapour and liquid phases and limiting accumulation of liquid phase heat transfer fluid about the first process stream passage(s) (19). Such heat exchangers can be used, among other applications, to replace a flash cooling stage in a Bayer process plant.

摘要： The invention relates to a method for exchanging heat contained at a fluid. A gas which is heated indirectly and emits infrared radiation is used as the fluid, said fluid being guided to the heat exchanger via an inlet and through art absorber chamber in the heat exchanger, and at least one surface, which absorbs the infrared radiation of the gas in order to use the heat of the gas, is provided in the absorber chamber. The mass flow and the temperature of she gas are additionally adjusted and the at least one surface which is absorbent for the heat exchange is designed such that the ratio Ψ of the heat flowing through the surface as a result of absorption to the total heat flowing through the surface is ≥0.6 during operation. Thus, a simpler and less expensive heat exchanger can be implemented.

摘要： A sealing mechanism is used to seal a sink of a case via a cover of a two-phase water-cooling heat dissipation device. The sealing mechanism includes a driving module and a guiding module. The driving module is disposed on the cover. The guiding module is linked with the driving module and includes a first connection component, a second connection component and a third connection component. The first connection component is driven by the driving module and includes a first constraining structure used to engage with and disengage from a restraining component for constraint of the cover. The second connection component is crossed by the first connection component. The third connection component is rotatably disposed on the cover. An end of the third connection component is connected to the second connection component, and the other end of the third connection component is connected to the first connection component.
