Abstract: A variable heatable radiator for use in a fluid circuit containing coolant therein, and which can generate substantial amounts of heat to heat larger spaces, such as in a home or business, while utilizing minimal power to run, and which can be utilized in various implementations and configurations. The radiator can be selectively activated or de-activated by, for example, a cell phone or the like whereby the fluid circuit in the radiator can be monitored for time of use, temperature and cost of use. The circuit possesses at least one opening defined therein on sides of the radiator and top and bottom thereof which is in communication with the circuit, whereby a heating element can be inserted to heat the fluid.

Abstract: A composite resin part is fabricated by laying up a composite part on the mandrel mounted on a portable cart. The cart is used to transport the part layup as it is being cured by a heating and air circulation system on-board the cart.

Abstract: A mobile device for heating rooms, comprising radiant elements, each provided with two heat-conductor plates associated with each other to define a central portion and connected fluid-dynamically with each other by means of connection elements. A heated heat-carrying fluid is able to flow in the central portions and, through the connection elements, from one to the other of the radiant elements in order to heat the surrounding room. Each pair of heat-conductor plates comprises lateral walls which are distanced from the corresponding central portion so as to define respective peripheral zones. The mobile device also comprises heat-insulating elements able to be applied due to having substantially the same shape so as to cover at least a part of the peripheral zones of the lateral walls.

Abstract: An electrothermal oil radiator includes a radiating body (1), an electric-control box (2) mounted on the radiating body (1) and a heating body (3) located inside the radiating body (1). The radiating body (1) includes a plurality of radiating fins (11) linked in turn. Each radiating fin (11) is hollow and sheet-like and has at least two oil leading grooves (12) inside thereof. Hollow connecting sleeves (13) extending horizontally are formed or mounted on upper and lower ends of each radiating fin (11). An oil leading hole in communication with the oil leading grooves (12) is formed in each connecting sleeve (13). The sleeves (13) on each radiating fin (11) are connected together to form a sealed oil cavity in which heat conducting oil is filled. A reinforcing radiating fin (4) is mounted between two adjacent radiating fins (11).

Abstract: A home heating radiator using a heat transfer fluid operating in phase change form, includes a reservoir of heat transfer fluid, and electric resistance heat source, for raising the temperature of the heat transfer fluid to a temperature such as to cause a phase change of the fluid, and a heating body where heat transfer takes place with the ambient air, the heating body including a number, n, of channels, communicating in the lowermost part of the reservoir, where n may be equal to 1.

Abstract: A portable radiator has a radiator body whose radiating members are defined by first and second metal plates which together define central portions in which a heating fluid is displaced convectively, the radiating members communicating with each other through passages in the central body. A heating unit is provided in the central body for heating the fluid and an additional heating member is provided in seats formed by the heating members outwardly of the central body for heating air.

Abstract: The independently operating and mobile radiator including a body having a plurality of radiating members each defined by a first metal plate and a second metal plate mutually associated and by a central portion wherein heated fluid circulates at a temperature preset by a resistance, the radiating members are mutually connected through passage hubs for circulating the heated fluid inside said body, each radiating member has one region of its surface, external to the central portion, having a wall thickness equal to the thickness of the first and second metal plates.

Abstract: A space heater is disclosed, comprising a housing, a heat source within the housing and a plurality of openings to allow the convection of air through the housing, in which: the heat source comprises a pair of panels defining between them a closed compartment, a liquid within and partially filling the compartment and an electrical heating element extending within the compartment, substantially parallel to the panels and in thermal contact with the liquid; the compartment is sub-divided into a lower liquid chamber and an upper expansion chamber and the cross-sectional area of the liquid chamber where it meets the expansion chamber is less than that of the expansion chamber; and the openings in the housing allow radiant heat from the heat source to escape from the housing. In further embodiments, the lower liquid chamber contains liquid at room temperature, but the upper expansion chamber does not.

Abstract: A thermosyphon radiator comprising a sealed panel is formed into two or more discrete chambers, each containing a reservoir of vaporising liquid in a lowermost part of the panel and a heating member extending with clearance through the lowermost part of the panel, the member being at least partially immersed in the vaporising liquid.

Abstract: Radiator, particularly for heating rooms, including a main body defined by several radiating elements (3) having hot fluid flowing therein, each of the radiating elements being defined by at least a first and second sheet elements (6,7) having a plurality of apertures (9) for reducing the temperature on the external perimetric surface of the radiating elements; at least one of the apertures (10), besides the reduction of the temperature on said external surface, prevents the deformation of the sheet of the radiating elements while welding together the first and second sheet elements.

Abstract: An oil radiator, particularly for heating rooms, includes a main body defined by a plurality of mutually associated radiating elements in which a diathermic oil heated by an electric resistor circulates. Each radiating element includes a pair of mating shaped plate-like elements joined together by welding to form an oil receiving space therebetween and each having lateral surfaces provided with a series of folds which mate with the corresponding folds of the other plate-like element to define a channel-shaped air flow compartment capable of lowering the surface temperature of the oil radiator below that of the oil contained in the radiator, thus reducing burn injuries caused by inadvertent contact with the radiator. The folds also cooperate to provide the radiator with planar lateral outer surfaces to minimize impact injuries caused by collision with the radiator.

Abstract: A stove with pyrolytic self-cleaning includes an oven having a cooking chamber to be heated and pyrolytically self-cleaned. An automatic pyrolysis system recognizes a limit value for soiling and controls pyrolytic self-cleaning. The automatic pyrolysis system includes a limit value comparator and a pyrolysis trigger connected to the limit value comparator.

Abstract: A plate heat exchanger designed as a heat tube in the form of a multi-layer expanded partly laminated body has an integrated, fluidically continuous large-surface channel structure. Formed in the vicinity of the outer edge is a condensate-collecting channel which is fluidically connected unobstructedly to the channel structure. A heating bar or a heating channel is arranged near the edge separately but connected heat-conductively. To prevent condensate from flowing off on one side within the condensate-collecting channel as a result of gravity and/or horizontal acceleration and thereby to ensure the best possible heating effect, the condensate-collecting channel is subdivided into condensate pockets by a plurality of flow obstacles.
