example 1

[0046] Example 1: The following calculation shows an example of the theoretical temperature of hydrogen and argon in a closed system with heat exchange at the periphery, and the peripheral velocity (vp) is 400m / s. 1 = entrance, 2 = periphery, 3 = exit. Since the flow rate in the fluid channel can be relatively low, the resistance, pressure, and temperature drop are in a small percentage, so they can be ignored.

[0047] T1-2=ΔT3-2 has the same cp (cp=heat capacity under constant pressure)

[0048] vp=400m / s, cp h2=14320J / kg K, cpAr=520J / kg K

[0049] ΔT h2(1-2)=vp 2 / (2×cp)=400 2 / m / s / (2×14320J / kgK)= 5.6K

[0050] ΔT Ar(1-2)=vp 2 / (2×cp)=400 2 / m / s / (2×520J / kgK)= 154K

[0051] Under the same quality cp, the maximum heat exchange T is equal to:

[0052] T=(((ΔAr-(ΔT h2×cp masse Ar) / (cp masse h2))) / 2=(154K-5.6K) / 2= 74.2K

[0053] This means h 2 The heat exchanger on one shaft end can provide 74.2K higher than the ambient temperature, while on the other shaft end, the argon gas is provided ...

example 2

[0054] Example 2: By using air as a heating fluid in an open system such as a heat exchanger, and using argon as a pressurized cooling fluid in a closed circuit, double the mass cp in the heat exchanger 106 = (1000×2kJ / kgK) / (520kJK)= 3.85 .

[0055] vp=400m / s, cp luft=1000J / kg K, cpAr=520J / kg K

[0056] ΔT Ar(1-2)=vp 2 / (2×cp)=400 2 / m / s / (2×520J / kgK)= 154K

[0057] ΔAir(1-2)=vp 2 / (2×cp)=400 2 / m / s / (2×1000J / kgK)= 80K

[0058] ±ΔT=(((ΔAr-(ΔT luff×cp mass air) / cp mass Ar)))) / 2

[0059] ±ΔT=(((154K-(80K×1000J / kgK) / 3.85×520J / kgK))) / 2= 57K

[0060] This means that at the outlet of the heat exchanger, the air is 57K higher than the ambient temperature, while the argon is 57K colder than the ambient temperature. The air must be pressurized and supplied to the periphery for heating.

[0061] But if the air under constant pressure is cooled by argon at the outlet or outside the outlet through its heat exchanger, both the air and argon will have a T slightly higher than the ambient temperature, a...

Abstract

It is a purpose for the invention to provide a rotating device (107) to generate heat, cold and pressure from the outlet at the rotation axis, by centrifugation pressurized fluid in that it include at least two under-supported U-channel structures (107) where one of the channels (104, 105) from each U-channel structure (107) toward the periphery (107) is in thermal contact, forming a heat exchanger (106) where one of the channels (105) contains a compressible cooling fluid which develops heat from the centrifugal compression in the channel (105), and the heat is transferred to a heating fluid with a lower temperature in the second channel (104) in heat exchanger (106) toward the periphery (107) where heat exchanging ceases, and the U-channels (107) is connected to its inlet - (101, 102) and outlet channels (111, 112 ) at the rotation axis for the transport of said fluid through the U-channels (104, 105, 108, 109) via the periphery (107), which after the outlet (111 ) for heating fluid is heat-exploited, and cooling fluid (112) is cold-exploited, and the heating fluid before the outlet(111) is pressurized by the heat received in the heat exchangers (106), and the cooling fluid is compressed with an adapted circulation pressure before inlet (102) to compensate against emitted heat in heat exchangers (106), and an expansion work of the heating fluid reduces the supplied energy to the compression work of the cooling fluid, and U-channel structures is rotated by appropriate means, and the U-channels are arranged radial and in balance around the rotation axis.

Description

Technical field [0001] The invention relates to the generation of heat in a pressurized fluid by means of centrifugal force. Background technique [0002] Various devices are known that rotate to compress a fluid using centrifugal force, and then the fluid is heated to deliver heat to another fluid or medium at the periphery of the device. [0003] What these devices have in common is that one of the fluid drives the device through a nozzle located at the periphery, and the fluid is transported through the device using only centrifugal force. [0004] Due to the large pressure difference between the inside and outside of the nozzle at the periphery, a high velocity is generated in the fluid, and there is corresponding friction and turbulence. If the nozzle rotates backwards in the direction of rotation, this movement also generates rotation resistance and friction. As a result of these trends, efficiency is reduced. [0005] When the fluid is a relatively humid gas, when the gas emi...
