Abstract:
La présente invention concerne un dispositif échangeur de chaleur comprenant un serpentin (120) comportant une entrée (122) et une sortie (124) de liaison avec un circuit de fluide caloporteur primaire (200) et un ballon (150) dans lequel est placé ce serpentin (120), lequel ballon (150) est rempli d'un fluide caloporteur secondaire et comporte une entrée (152) et une sortie (154) de liaison avec un circuit secondaire (300), le serpentin (120) dans lequel circule le fluide caloporteur primaire logeant un serpentin secondaire (130) pour former un échangeur solénoïde à tubes coaxiaux et l'une des liaisons (152, 154) avec le circuit secondaire (300) étant reliée directement avec l'une des extrémités (132, 134) du serpentin secondaire (130), tandis que l'autre liaison (154, 152) avec le circuit secondaire ainsi que la deuxième extrémité (134, 132) du serpentin secondaire (130) débouchent dans le ballon (150), de sorte que les échanges entre le fluide caloporteur primaire et le fluide caloporteur secondaire, dans l'échangeur solénoïde à tubes coaxiaux s'opèrent à la fois en convection forcée à l'intérieur de celui-ci et en convection naturelle à l'extérieur de celui-ci, caractérisé par le fait que le départ (154) du fluide secondaire est relié directement avec une extrémité du serpentin secondaire (130), tandis que le retour (152) du fluide secondaire débouche librement dans le ballon (150).
Abstract:
A multi-stage cooling system comprises a compressor, a condenser, a first heat exchanger, and a second heat exchanger. The exchangers comprise a vessel for containing a refrigerant, the vessel having an inner space bounded by a closed surface of a vessel wall, the vessel comprising an inlet and an outlet for transport of refrigerant into and out of the inner space through the vessel wall. A tube is disposed at least partly inside the inner space, wherein a first end of the tube is fixed to a first orifice of the vessel wall and a second end of the tube is fixed to a second orifice of the vessel wall to enable fluid communication into and/or out of the tube through the first orifice and the second orifice. A refrigeration cycle is formed.
Abstract:
A heat exchanger comprising: - a first pipe (2) for the passage of a first fluid; - a solidified metal porous foam (4); The first pipe (2) comprises a plurality of sections which: - develop inside the foam (4); - are in series; - are integrated into a first portion of the first pipe (2), said first portion defining a single block, said single block being a single and not an assembled piece and being serpentine-shaped.
Abstract:
Acclimatization system including at least a first circuit (1) inside of which flows a first fluid carrying heat or cold, coming from at least one heat pump (2), which cools or warms up the first fluid; the first circuit (1) is combined with a second circuit (3) wherein besides the serpentine of the first circuit (4) also flows a second fluid on a closed circuit with the same or opposite directions to the first circuit (1), which can include an inert body for control of the second fluid flux (3); and this second circuit (3) is mechanically powered by a circulating fluid pump (5), or similar mechanism. It also includes one serpentine of the second circuit, which at its beginning and end has temperature and relative pressure measure means (7) for controlling the mentioned heat pump (2) freezing or heating the second fluid which in contact with the serpentine of the first circuit (4) will heat up or cool down, depending on the desired effect, and flows to the thermo-ventilators (8) that dissipate the heat in the area to be acclimatized, reentering on the second circuit (3) repeating the whole process on a closed circuit. The present invention is applicable to the acclimatization of areas, such as houses, industries, warehouses, storehouses and offices, as well as on open circuit in acclimatization of fluids and sanitary waters.
