The invention relates to a composition for producing a heat-insulating coating comprising at least one radiation-absorbing compound and at least one IR-reflector component, to a heat-insulating coating comprising this oriented, cured composition, and to a process for producing said coating.

The invention relates to an air-cooled combustion chamber wall for combustion furnaces. The combustion chamber wall comprises at least one masonry wall with a space in the middle for the passage of cooling air along the side of the wall away from the combustion chamber side. To create a simple, stable and effective structure, the invention proposes that the masonry be made of bricks, whose walls enclose at least one air duct.

A heat exchanger of a ventilating system includes: heat exchange plates having first air passage through which indoor air being discharged to outside of a building passes and a second air passage through which outdoor air being introduced to the interior of the building passes which are sequentially formed: first corrugation plates attached to the first air passage; and second corrugation plates attached to the second air passage, wherein the heat exchange plates are made of a paper material with numerous fine holes that are able to generate a capillary phenomenon and loess which radiates far infrared ray. Heat exchange and moisture exchange between the indoor air and the outdoor air are performed simultaneously, and a cleaning function of removing a harmful material contained in outdoor air can be carried out.

The present invention concerns a device for securing an insulation board within a cavity wall, comprising an inner wall, an outer wall and a cavity in between said inner and outer walls in which insulation boards are accommodated, said device comprising: wall anchor means (5) for securing the inner wall to the outer wall; retaining means (7,7') for fixating an insulation board in the cavity; said retaining means including projections (7) gripping an end portion of the insulation board; wherein the retaining means include a mounting element (6) adapted to be fastened to the inner wall; the anchor means comprises an elongated member (5) with holding means (13), which cooperate with corresponding receiving means (16) on the mounting element for securing the anchor member to the mounting element; and the projections (7) are formed in the mounting element. Hereby, a better insulation quality may be achieved as the insulation boards may be positioned against a smooth inner wall without any wall ties pre-mounted, on which the insulation panels otherwise could be damaged. The insulation mounting procedure becomes much simpler and easier by a device according to the present invention, saving a considerable amount of time and consequently labour costs.

The device (10) has at least one resistance heating element and a heat conducting flat envelope (20) enclosing the resistance heating element for outputting heat to the medium to be heated. At least one temperature detection element with electrical connections is arranged inside the envelope with its connections in a connection region (20c) of the envelope. The envelope edges are joined in a sealed manner.

The invention relates to a cooling device ( 1 ) for cooling an item to be cooled, especially for use in the examination, handling and processing of cryogenic samples. The device includes a cooling compartment ( 3 ) for receiving the item to be cooled, an inner wall defining the cooling compartment ( 3 ), an outer wall, a space between the outer wall and the inner wall, and a coolant feed line ( 11 ) for feeding a coolant. According to the invention, the coolant feed line ( 11 ) leads into the space between the inner wall and the outer wall and feeds the coolant into the space, the inner wall being permeable for the coolant.

The invention relates to a cooling system, with a cooler (1) taking up heat, for a permanently-energized synchronous motor, in particular, a motor for a locomotive. A first line (2) leads from the output of the cooler (1) to the input of a recirculation cooler (4), emitting heat to the environment. A second line (5) leads from the output of the recirculation cooler (4) to the input of the cooler (1). A first non-return valve (3), permitting flow towards the recirculation cooler (4), is arranged in the first line (2) and a second non-return valve (7), permitting flow towards the cooler (1), is arranged in the second line (5).

Thermal insulation of a metal structure used in cryogenics comprises applying a first epoxy resin coating to the surface, applying a 5 mm polyurethane (PU) foam layer, measuring the thickness and forming a further PU layer.
