In one aspect, a self-powered pump for heated liquid is provided. The pump includes an airtight container for containing the heated liquid. A heated liquid inlet pipe extends upwardly into the container such that its end is within the container. A heated liquid outlet is lower than the end of the inlet pipe. A breathing pipe extends upwardly into the container such that its end is within the container and is higher than both of the outlet and the end of the inlet pipe but lower than an interior side of the container top. An opposite end of the breathing pipe is outside the container, lower than the container base, and is received by an open container such that the opposite end can become submerged in heated liquid accumulated within the open container during pump operation. A fluid or liquid heating system incorporating the self-powered pump may operate without external power for the pump. In another aspect, a fluid heating and storage tank is provided. The tank includes a storage tank for a primary fluid having a primary fluid inlet and a primary fluid outlet and an apparatus for flowing a secondary fluid through the storage tank in isolation from the primary fluid. The apparatus includes first and second pipes and a heat exchanger. The first pipe extends through the storage tank and is mounted at its ends to first and second fittings in the wall of the storage tank. The second pipe also extends through the storage tank and is mounted at its ends to third and fourth fittings in the wall of the storage tank. The heat exchanger is disposed within the storage tank and fluidly interconnects the first and second pipes. The tank may be capable of standing in more than one orientation. A fluid heating system including the fluid heating and storage tank and a heater may or may not, in different embodiments, use a pump to circulate secondary fluid through the heater, which may be a solar heater.

A solar chimney includes a solar collector which heats air in the chimney, producing updrafts which can be harnessed to perform useful work. The solar collector may be located inside or outside the chimney. The device may include a reservoir for storing a heat transfer fluid, thus enabling the device to be used during both day and night. The solar chimney may be equipped with both internal and external solar collectors, operating in parallel. The solar chimney may also be equipped with multiple external solar collectors, connected in parallel to a reservoir. The solar chimney of the invention provides a convenient and practical way to convert solar energy into electrical power.
摘要:
A heat exchanger is comprised of a plurality of chambers, wherein each of the plurality of chambers having a repeating pattern of shapes wherein each of the plurality of chambers consists in a pair of deflectors wherein each one is a mirror image of its opposite deflector but shifted approximately half a the wall length and all of the plurality of chambers causing multiple passes by the same air through multiple sections of a coil consisting in a long winding pipe, containing a heat transfer liquid, wherein the coil is passing through all the plurality of chambers. Each of the deflector redirecting the air stream and causing a uniform redistribution of air molecules along the coil section. Each of the wall length being defined by a specific sequence of components starting with a rounded wall from which extends a shear barrier and the wall terminated by a diverter.
