The method for soldering components (5) such as heat exchanger or absorber module of solar collector, which partially consist of aluminum or aluminum alloy, comprises heating the component under use of a near-infrared (NIR) radiation source (3, 3') at soldering temperature. A soldering position arranged in the interior of the component is soldered, where the components are soldered or heated under use of the NIR-radiation source in vacuum or in controlled atmosphere. The NIR-radiation source is used only for heating the components to be soldered. The method for soldering components (5) such as heat exchanger or absorber module of solar collector, which partially consist of aluminum or aluminum alloy, comprises heating the component under use of a near-infrared (NIR) radiation source (3, 3') at soldering temperature. A soldering position arranged in the interior of the component is soldered, where the components are soldered or heated under use of the NIR-radiation source in vacuum or in controlled atmosphere. The NIR-radiation source is used only for heating the components to be soldered. The components partially consist of high temperature coating, which selectively absorbs in NIR-wavelength range. The exhaust heat of the NIR radiation source is used for conventional heating of the components to be soldered, where evacuatable solder gauges are used for carrying out a vacuum soldering. The temperature of the components is measured in heating area under use of a pyrometer (7). The heating of the component is carried out at soldering temperature in less than 5s. An independent claim is included for a component such as heat exchanger or absorber module of solar collector. |
