DETAILED DESCRIPTION OF THE INVENTION The present invention provides heat transfer V7tw by solid, gaseous reversible reactants.
Concerning the change of faith.

In this conventional device, the alloy powder, which is an endothermic and exothermic substance, does not flow, and by switching the heat exchange mechanism, a reverse reaction occurs between the two Hashira alloys by combining with hydrogen, absorbing heat through decomposition, and dissipating heat. was.

However, according to this MIIK, the temperature of the alloy filled container changes periodically, so the temperature obtained is unstable and difficult to control, and sensible heat loss is large, and heat conduction and

An upper heat exchanger 'a61, a first lower heat exchanger 62, a second upper heat exchanger -08, and a second lower heat exchanger 64 are provided. The first upper hopper 1 on the low-temperature side stores a low-temperature-side alloy powder MA serving as a reverse melonization material, such as L4, FeTi, and the second upper hopper 8 on the high-temperature side stores a Vi island am alloy powder MB. For example, C

Upper Autosigian Mizumoto Gas Passage 81. The lower hydrogen gas passages 82 are provided with filters 81m and 82m, respectively, to allow gas to flow through them.

Next, I will explain the work @utat.

In the figure, MA gold alloy second upper hopper 8 (K MB) 1m alloy is put into the first upper hopper 1, and the first upper heat exchanger 611

The pulp from the upper hopper 1.8 of the ij 84 passes through the upper rotary pulp 61 and 68, and is then dropped into the lower hopper 2.4. Then, when the rotary pulp 61, 58 is closed and a temperature Tm is supplied to the first lower hopper 2 and the second lower hopper 4, respectively, MAR, →MA+)1. reaction takes place. Then, this dissociated ratio enters the second hopper 4' through the lower hydrogen gas passage 82, where M B +H*-M
A BH* reaction occurs. Then, the heat medium of the first lower heat exchanger 62 is cooled and flows out, and the heat gFi supplied to the second lower heat exchanger 15i64 rises to the temperature "rh" and is taken out.

By supplying a low-temperature heat medium, the high-temperature heat of Th is underestimated. (Here, the temperature is in the relationship T l (Tm (T h )) According to the above, since the alloy powder is circulated in the hopper, an exothermic endothermic reaction occurs in the hopper, and heat loss due to heat is caused. The resulting temperature Th is maintained at a stable temperature.Therefore, the reckless switching such as the conventional heat pump V stem is not done in a horizontal position69, but the heat transfer is improved by flowing the alloy powder. can be expected.

At this time, hydrogen gas flows through the passages 81 and 82 under a reverse pressure.

In addition to heat pumps, this V-stem can also be used for side heat boilers, air conditioners, and refrigerators.

Note that the present invention is also applicable to other solid gas reversible reactants.

The present invention enables exothermic and endothermic reactions to occur in the same container by circulating and flowing the alloy powder configured as described above, and the temperature of the container does not change, reducing the amount of heat lost as heat from the container. temperature is stable. This device not only simplifies the V-can and makes it possible to use the rounded contaminated gas and waste liquid, but also improves heat transfer through the flow of alloy powder. It became a privilege to gain.
