A method of cooling moist air through a heat exchange surface suppresses the formation of dew and frost on a heat exchange surface by preparing a carrier which has a heat conduction ratio higher than that of the moist air if the air temperature in a temperature boundary layer, is below the dew-point when the air temperature in the temperature boundary layer is above 0 C., or below the freezing-point when the air temperature in the temperature boundary layer is below 0 C., the carrier being arranged within the temperature boundary layer and on the heat exchange surface, which is in contact with moist air and is used for cooling; and removing moisture from the air by condensing or sublimating water vapor in the moist air on the surface of the carrier by arranging the carrier opposite of the heat exchange surface and within the temperature boundary layer.

A motor vehicle includes a radiator. A cover is arranged on the radiator and covers the radiator at a specific place to prevent damage to the radiator in the event of an impact or crash.

A protection element for vapor chamber includes a main body and a protection element. The main body is divided into a working zone and a sealing zone. The sealing zone is located around an outer periphery of the working zone and is provided with a notch area, to which a fluid-adding and air-evacuating pipe is connected. The protection element is correspondingly mounted to the notch area to contact with the sealing zone of the main body. With the arrangement of the protection element, the fluid-adding and air-evacuating pipe is protected against collision and impact and accordingly, the main body of the vapor chamber is protected against vacuum and working fluid leakage.

A container for a waste heat utilization circuit may include a housing that defines a housing interior such that the housing interior can be flowed through by a working medium. A sheath may be arranged in the housing interior for accommodating an auxiliary medium. The sheath may be fluid-tight and heat-conductive at least in certain areas. The sheath may define a sheath interior of variable volume.

The system and method for installing external corrosion guards of the present disclosure comprises a method of protecting tubing in tubular heat exchangers from external corrosion that includes the installation of protective collars or guards around the tube outer diameter at the tubsheet plate, anti-vibration baffle, and/or pass partition plate levels. The external corrosion guards can be installed using a ridge method, where a ridge sits on a plate level, using a mechanical expansion method, and using a mechanical rolling method.

Embodiments of the present disclosure relate to a fixing device for a double-sided heat sink and an associated heat dissipating system. There is exemplarily provided a fixing device for mounting the double-sided heat sink on a carrier, The fixing device comprises: a first holder including a first cylindrically-shaped rod, wherein the first cylindrically-shaped rod can pass through a first cooling portion of the double-sided heat sink and a mounting hole of the carrier to fix the first cooling portion to a first side of the carrier, and the first cylindrically-shaped rod comprises a through-hole extending along a longitudinal direction; and a second holder including a second cylindrically-shaped rod, wherein the second cylindrically-shaped rod can pass through a mounting hole of a second cooling portion of the double-sided heat sink and the through-hole of the first holder, such that the second holder is coupled with the first holder to fix the second cooling portion to a second side of the carrier opposite to the first side.

A heat exchanger for a fuel cell is disclosed. The heat exchanger includes at least two tube bodies that are arranged at a distance from one another and are in each case structured so that a fluid can flow through internally and so that air can flow around externally. A water channel, through which water can flow fluidically separated from the fluid, is arranged in or on at least one tube body. At least one opening, via which the water channel communicates fluidically with an external environment of the at least one tube body, is provided on the at least one tube body. The at least one opening is arranged in the at least one tube body so that at least one of the tube bodies can be wetter with water, which is guided through the water channel and escapes the water channel through the at least one opening.

A high corrosion resistance heat exchanger is disclosed, which has improved corrosion resistance. The improved corrosion resistance is achieved by controlling alloy components in a tube material and a fin material and inducing sacrificial corrosion of the fin material. The high corrosion resistance heat exchanger includes a tube having a channel formed therein to allow a refrigerant to flow, and a plurality of fins coupled to the outer circumferential surface of the tube. The fins may contain 0.1 wt % to 0.45 wt % of Mg, and 0.5 wt % to 0.8 wt % of Zn, a remainder wt % of Al.

Disclosed is a heat exchanger having heat exchange plates and a base plate that can help to mitigate the thermal stresses encountered by a heat exchanger, particularly, around the peripheral edge portions of the heat exchanger and the base of heat exchanger. This is achieved by providing a channel of coolant fluid near the peripheral edge portions which is in between the peripheral edge portions and the manifold permitting flow of hot fluid. In addition, the base plate of the heat exchanger is protected from the hot fluid flowing through the manifold by providing deflectors that shield the base plate from the hot fluid.

In an all-aluminum heat exchanger using aluminum as a material of a refrigerant pipe, a dissimilar metal contact with a bottom plate, which is made of iron, of an outdoor unit increases a risk of corrosion of the refrigerant pipe. An outdoor unit for an air-conditioning apparatus includes a placement plate, which is provided on a bottom plate of a casing and has a heat exchanger placement surface having a planar shape on which the heat exchanger is placed. With this configuration, water and dust generated in the casing can be caused to drop from the heat exchanger placement surface to the bottom plate and discharged to an outside of the casing. As a result, even when the all-aluminum heat exchanger is used as a heat exchanger of an air-conditioning apparatus, leakage of refrigerant can be prevented.
