Embodiment

The utility model utilizes the combination of linear generator systems and VM circulating heat pump technology to realize the purpose of this utility model.While the work of VM circulating heat pump, can generate electricity and memory.

Whole system is made up of VM circulating heat pump and linear generator.VM circulating heat pump system is made up of cold cylinder, cold pushing piston, cold regenerator, hot cylinder, hot pushing piston, hot regenerator, room temperature chamber, cryogenic heat exchanger, room temperature heat exchanger, high-temperature heat-exchanging, the drive link mechanism of pushing piston, drive motor.System utilizes the heats such as waste heat, combustion of natural gas heat as the energy, from hot chamber and the heat absorption of cold chamber, in the heat release of room temperature chamber.

System needs drive motor to provide a small amount of machine power when starting working, at system normal operation period, time near the top that cold pushing piston is in it, hot cylinder volume is comparatively large, and in system, mean temperature is higher, and pressure is also higher.On the contrary, when cold pushing piston be in it bottom time, the volume of hot cylinder close to 0, in machine average Temperature of Working and pressure all lower, like this, hot cylinder serves the effect of driving.

Linear generator working principle: using the making material of permanent magnet as cold pushing piston, be wound around copper coil outside cylinder wall, constitute basic electricity generating device.As shown in Figure 3, when magnet moves downward, coil and magnet generation relative movement, according to Faraday law of electromagnetic induction, coil cutting magnetic induction line moves, and magnetic flux changes, and therefore creates electric current in coil.When magnet moves upward, magnetic flux changes, generation current in coil.But magnet movement direction is contrary, and the current direction therefore produced there occurs change.

Between cold cylinder and pushing piston, add positioning work piece, when pushing piston moving direction changes, automatic straightening current direction, makes output current keep in the same way.

The process of linear generator as shown in Figure 4.

Process (a), cold pushing piston, in neutral position, cold chamber, moves downward.Now generation current in coil, by accumulators store.

Process (b), cold pushing piston, at cold chamber lower dead point position, moves upward.Now generation current in coil, direction there occurs change.Positioning work piece simultaneously bottom cold chamber is triggered, and positioning work piece connects electric current displacement apparatus, and replaced by the current direction that coil produces, therefore current direction there occurs 2 changes, still with process (a) in the same way, by accumulators store.

Process (c), cold pushing piston, in neutral position, cold chamber, moves upward.Now generation current in coil, same to process (b).

Process (d), cold pushing piston, at cold chamber upper dead center position, moves downward.Now current direction there occurs change.The positioning work piece on top, cold chamber is triggered, and current direction is corrected by electric current displacement apparatus.Current direction still with process (a) in the same way.The electric current produced is by accumulators store.

As shown in Figure 2, through the location of positioning work piece to cold pushing piston, current direction is constantly corrected.Therefore galvanic current can be obtained.

Reason electricity generating device being arranged on cold chamber instead of hot chamber be hot cavity temperature greatly about about 930K, beyond the temperature range of normal array material, therefore select cold chamber as the riding position of electricity generating device.Select neodymium iron boron (Ne ₂fe ₁₄b) permanent magnet material.

The magnetic of magnet can not be always constant, can decay in use for some time.Therefore permanent magnet piston to be regularly replaced to ensure the reliability of system.

For a VM circulating heat pump, compute dependent data, proves the feasibility of electricity generating device.

Now choose neodymium iron boron (Ne ₂fe ₁₄b) permanent magnet material, μ=1.5 μ ₀=4 π × 10 ^-7μ/m

B generally gets 1.1-1.52, now gets B=1.30T.Density p=7.5cm ^-3g.

The cold pushing piston diameter d of VM circulating heat pump ₁=3.48cm, cold pushing piston length l ₁=4.359cm,

The cold cavity length l of VM circulating heat pump ₂=50mm

Copper coil selected by coil, diameter d ₂=0.32mm

$H_m=\frac{B}{{\mathrm{\μ}}_0}=\frac{1.30T}{1.05\×4\mathrm{\π}{\×10}^{-7}\mathrm{\μ}/m}=0.0985\×{10}^{7}A/m$

I＝H _m·l ₁＝0.0985×10 ⁷×4.359×10 ^-2＝0.4285×10 ⁵A

$N=\frac{l_2}{d_2}=\frac{50}{0.32}=156.25\≈160$ Circle

$I_0=\frac{F}{N}=\frac{0.4285\×{10}^5}{160}=0.002678\×{10}^{5}A=2.678\×{10}^{2}A$

This patent is feasible.
