Functionalized textile materials are provided. At least a portion of a textile surface in includes a ceramic material, such as a binderless porous structured ceramic, and optionally, one or more functional layer is applied, resulting in a textile material with one or more desirable functional properties, such as hydrophilicity, hydrophobicity, flame retardancy, photocatalysis, anti-fouling, and/or deodorant properties.

A heat-dissipating substrate with a coating structure is provided. The heat-dissipating substrate includes at least two layers. A base layer is configured to dissipate heat, and one or more sputtered layers are formed on the base layer. The sputtered layer has a corrosion resistant property, a soldering ability, or a sintering ability. A thickness of the sputtered layer is less than 5 μm.

A heat exchanger includes a pipe made of aluminum, a thermistor, and an attaching portion with which the thermistor is attached to the pipe. The pipe carries a flow of refrigerant. The thermistor detects a temperature of the refrigerant. The pipe includes a sacrificial layer provided on a part of a surface of the pipe. The sacrificial layer is lower in potential than the aluminum of the pipe. The attaching portion is higher in potential than the sacrificial layer. At least one part of the attaching portion is attached to the surface of the pipe where the sacrificial layer is not provided. The attaching portion includes a brazed portion that is higher in potential than the sacrificial layer. The thermistor is attached to the pipe with the brazed portion.

A heat transfer unit for a motor vehicle may include a metallic heat transfer block and a base plate. The heat transfer block may include channels that are configured to be flowed through. The base plate may include an outer region and a material bonding region. The base plate may be exposed towards the outside and may be materially bonded to the heat transfer block in the material bonding region. The base plate may be formed out of an aluminium, an aluminium alloy, or a wrought aluminium alloy. The outer region of the base plate may comprise a protective coating produced by anodising at least in regions, and the material bonding region of the base plate may not have a protective coating produced by anodising.
